[02:09:19] <tiwake> is there a good house floor design thing I can use in linux?
[02:09:32] <tiwake> sketchup is windows/OSX only
[02:10:00] <XXCoder> maybe solvespace
[02:10:02] <XXCoder> its new
[02:10:17] <tiwake> and sketchup didnt look like it worked very well in wine
[02:10:17] <XXCoder> probably not though
[02:11:18] <tiwake> well, I'm at the stage where I cant decide how I want a floor plan to be, or really what I want in a house
[02:11:48] <tiwake> no basement, three stories is too tall
[02:11:53] <tiwake> other than that...
[02:12:10] <XXCoder> hmm make it 4d cube
[02:12:14] <tiwake> I know what I want for building materials, more or less
[02:12:14] <XXCoder> kidding
[02:12:18] <Jymmm> plumbing is always a good thing
[02:12:26] <XXCoder> why?
[02:12:32] <XXCoder> just use tubes to bring it outside
[02:12:38] <XXCoder> oh thats plumbing lol
[02:12:44] <Jymmm> that's lumbing
[02:12:53] <Jymmm> plumbing*
[02:12:53] <tiwake> cut a hole in the concrete floor
[02:13:24] <tiwake> ah, anyway
[02:15:15] <tiwake> egh... that one looks like a screen shot from the sims
[02:15:22] <XXCoder> well
[02:15:33] <XXCoder> sims with cheats can be pretty decent planner
[02:15:44] <tiwake> (looking at random house designs online)
[02:16:19] <tiwake> there are a couple things
[02:17:48] <tiwake> using ICF for the outer walls (maybe for a wall or two for the master bedroom for sound-proofing.. hehe) so the walls would be pretty strong in general, which would allow for a flatter roof. really steep roofs are evil XD
[02:18:07] <XXCoder> is there trees near house?
[02:18:17] <XXCoder> if so, steep is bit better, less roof shoveling
[02:18:25] <XXCoder> same for heavy snows
[02:18:29] <tiwake> true too
[02:18:38] <tiwake> no snow around here, just lots of trees
[02:18:43] <tiwake> (oregon coast)
[02:18:51] <XXCoder> other way is metal roof
[02:18:58] <XXCoder> there is couple cons but easy clean
[02:19:00] <tiwake> metal roof is going to happen
[02:19:30] <XXCoder> thinking about sims
[02:19:35] <XXCoder> it really can work as designer.
[02:19:43] <XXCoder> it even has funtures
[02:19:50] <tiwake> heh
[02:20:19] <XXCoder> no idea if it supports multifloor though
[02:20:23] <tiwake> never played it, dont have a copy of it, and dont have a copy of windows to run it on
[02:20:52] <XXCoder> yea I guess it means you gonna use something
[02:21:09] <XXCoder> solvespace might work but it is awkward compiling it from what I read
[02:21:16] <tiwake> I was thinking about pencil and paper really
[02:21:28] <XXCoder> windows version would work in wine if hardware accercation enablked
[02:22:08] <tiwake> oh gosh so many things I could do
[02:22:14] <tiwake> for the house
[02:22:37] <XXCoder> just be sure you has a shop you'll be fine lol
[02:22:47] <tiwake> thats the other thing
[02:23:02] <tiwake> do I want a garage and shop to be the same building?
[02:23:08] <tiwake> should it be attached to the house?
[02:23:18] <XXCoder> well can be seperate by 3 feet or so
[02:23:28] <XXCoder> cheaper insurance and 3 feet is nothing even in heavy rain
[02:23:51] <XXCoder> well dunno about your insurance and state definitions
[02:23:58] <roycroft> in many places a detached garage increases property taxes by quite a bit more than the same size attached garage
[02:24:08] <tiwake> thats a good point
[02:24:25] <XXCoder> roy really? I would think it'd be cheaper since less fire risk
[02:24:33] <Jymmm> Insurance is higher on a detached garage too
[02:24:33] <XXCoder> propety tax ahh
[02:24:35] <tiwake> optimize house, garage, and shop design for tax purposes
[02:24:41] <roycroft> property taxes have nothing to do with fire risk
[02:24:43] <XXCoder> and insurance
[02:24:47] <roycroft> that's a matter for insurance
[02:24:58] <XXCoder> yeah I misread what you said roy
[02:25:17] <roycroft> i'd check into all of those things before deciding what to do
[02:25:25] <XXCoder> permissions too
[02:25:38] <roycroft> yes, zoning regulations are also important
[02:25:46] <XXCoder> seperate may mean he has to pay 2 permissions, house and garage vs one thing
[02:26:35] <roycroft> all other factors being equal i personally would prefer a detached shop with a covered walkway between it and the house
[02:26:55] <roycroft> i'd keep some things in the house though, such as my electronics workbench
[02:26:55] <XXCoder> careful with "covered" with laws definitions
[02:27:05] <tjtr33> sketchup ver 9 runs well under wine and ubuntu 10.04
[02:27:08] <tjtr33> i use it a lot
[02:27:24] <roycroft> i'm ignoring all those factors, xxcoder
[02:27:54] <roycroft> currently i use my attached garage as my main shop
[02:27:57] <XXCoder> yeah just need to be careful, for example connected roof may make it into one thing in eyes of law not house and garage for exampkle
[02:28:02] <tjtr33> make that ver 8, just checked
[02:28:03] <roycroft> i do woodworking, machining, and brewing in it
[02:28:06] <roycroft> as well as laundry
[02:28:16] <roycroft> i have a detached building that i use as a welding/grinding/painting shop
[02:28:31] <roycroft> my painting tent can be set up in the garage or the welding shop
[02:28:34] <Jymmm> bathroom (with shower) in shop/garage
[02:28:56] <XXCoder> living room spa room
[02:31:04] <XXCoder> heh I did read about people actually putting spa in living room
[02:31:06] <XXCoder> insane.
[02:31:13] <XXCoder> spa is heavy
[02:33:39] <Jymmm> un ground spa
[02:33:43] <Jymmm> in*
[02:33:59] <XXCoder> One I read about it was in second floor
[02:34:08] <XXCoder> I'm amazed house floor managed to hold
[02:34:17] <Jymmm> that's just dumb
[02:34:29] <XXCoder> indeed
[02:34:38] <Jymmm> unless it was like a split level
[02:35:32] <XXCoder> maybe it was that. been a long while
[02:46:12] <Jymmm> You could, but if there ever was a leak...
[02:46:27] <XXCoder> free house rot!
[02:46:35] <XXCoder> supply is limited
[02:46:58] <XXCoder> smart kid. https://i.chzbgr.com/maxW500/8461574144/h0DEC93EF/
[02:53:07] <Jymmm> lol or smartass, either works =)
[02:53:19] <XXCoder> yep
[02:55:44] <tiwake> hmm
[02:55:50] <tiwake> where can I get sketchup 9?
[02:56:01] <tiwake> or 8 :P
[02:56:02] <XXCoder> isnt sketchup google?
[02:56:16] <tiwake> used to be, I think they sold it recently
[02:56:33] <XXCoder> wonder if theres site for older versions
[02:56:46] <tiwake> tiz what I'm looking for
[02:58:09] <XXCoder> http://www.cracked.com/blog/8-stupid-kitchen-hacks-tested-usefulness/ the section on butter is funny
[02:59:30] <tiwake> http://filehippo.com/download_sketchup/9114/
[02:59:43] <tiwake> not sure I trust that source
[02:59:50] <XXCoder> dunno too
[03:00:08] <XXCoder> the egg hack is fine if its for yourself, definitely not reserant usable hack :P
[03:00:22] <XXCoder> (second page not suck yolk one)
[03:01:16] <Jymmm> easiest to just do it in your hand.
[03:01:35] <XXCoder> I remember this tip of putting eggs in vingear for a bit before boiling
[03:01:41] <XXCoder> 'so it peels off easier
[03:01:47] <XXCoder> may not be vingear
[03:01:58] <tiwake> nitric acid?
[03:01:59] <Jymmm> salt or baking soda
[03:02:14] <XXCoder> youre right
[03:02:38] <Jymmm> who's right?
[03:02:42] <XXCoder> you
[03:02:46] <XXCoder> http://www.thekitchn.com/are-hardboiled-eggs-easier-to-peel-if-you-add-baking-soda-to-the-water-putting-tips-to-the-test-in-the-kitchn-202522
[03:02:46] <tiwake> oh nice
[03:02:54] <tiwake> I'm right
[03:03:02] <XXCoder> lol
[03:03:07] <XXCoder> fine Jymmm
[03:03:11] <XXCoder> *is right
[03:03:12] <Jymmm> Eh, in actuality as long as the eggs are NOT fresh, they peel easily
[03:03:34] <XXCoder> its almost always "glued on" here
[03:03:49] <XXCoder> results are mixed apparently
[03:05:42] <tiwake> the garlic one is funny
[03:05:57] <XXCoder> yeah
[03:06:30] <Jymmm> garic is SUPER esasy to peel
[03:06:31] <tiwake> lol
[03:06:37] <tiwake> I love garlic so much
[03:06:48] <tiwake> screw you garlic haters
[03:06:49] <tiwake> haha
[03:07:45] <Jymmm> Place a whole head of garlic in a metal bowl, place another metal bowl on top, shake like hell. Garlic completely peeled. (seriously)
[03:09:26] <tiwake> step 1: buy peeled garlic in 5lb bags
[03:09:37] <Jymmm> https://www.youtube.com/watch?v=0d3oc24fD-c
[03:10:34] <tiwake> http://img.21food.com/20110609/product/1307482605239.jpg
[03:10:38] <tiwake> oh gosh
[03:10:45] <tiwake> garlic gasm
[03:10:52] <tiwake> I love garlic so much
[03:10:56] <XXCoder> :P
[03:11:19] <Jymmm> 4000 clove chicken, and a small diet soda.
[03:11:44] <tiwake> diet soda? blarf
[03:12:26] <XXCoder> oh I read bit ago that apparently scientists figured out how to unscamble egg
[03:12:33] <tiwake> yeah
[03:12:34] <XXCoder> cook and scamble it, they can undo it
[03:12:43] <tiwake> protein folding
[03:12:45] <tiwake> research
[03:12:58] <XXCoder> its bit odd but maybe something useful will be found.
[03:13:00] <tiwake> though its still not quite the same... heh
[03:13:25] <XXCoder> I had to laugh a bit. one of plots in thursday next book series has unscambled egg recipe thats basis of time travel
[03:13:41] <tiwake> it is rather useful... because of how proteins arrange themselves in dense clusters, like an egg or skin cells or w/e
[03:19:49] <renesis> eggs are neat
[03:20:29] <Jymmm> and tasty
[03:20:47] <renesis> ya
[03:22:39] <Deejay> moin
[04:07:56] <XXCoder> diy surface grinder dang
[04:08:24] <XXCoder> http://www.hossmachine.info/projects_4.html#surface%20grinder
[04:34:10] <XXCoder> http://kukuruku.co/hub/diy/usb-killer
[04:34:12] <XXCoder> insane
[05:52:34] <ReadError> hey guys
[05:52:41] <ReadError> whats the tool called that does this.. http://www.ahsystems.com/catalog/data/info/oc530.jpg
[05:52:48] <ReadError> camfer ?
[05:52:56] <ReadError> rounds the end of a tube
[05:53:25] <ReadError> er chamfer isnt it
[05:56:50] <archivist> it that started as tube then it has been formed rather than cut
[05:56:54] <archivist> if
[05:57:23] <ReadError> yea
[05:57:29] <ReadError> i want to round the end
[05:57:41] <ReadError> of brass/copper tube
[05:58:11] <archivist> cutaway drawing?
[06:00:16] <archivist> are you wanting http://en.wikipedia.org/wiki/Metal_spinning
[06:01:11] <ReadError> yea
[06:01:16] <ReadError> something i can chuck in a lathe
[06:01:25] <ReadError> and press a tube into to reduce it
[06:02:14] <archivist> other way round, tube in a collet on a former, tool leans on it
[06:02:50] <archivist> you want to upset the metal, may need annealing mid process
[06:03:03] <ReadError> its not structural
[06:03:21] <ReadError> is there a name for said device/tool?
[06:03:26] <archivist> it hardens then wrinkles or splits
[06:03:54] <archivist> hence need for the annealing, can only go so far
[06:04:54] <archivist> it may be sensible to start with flat sheet on a spinning lathe
[06:05:46] <ReadError> im only using 5mm tube
[06:05:58] <ReadError> and reducing it to 2-3 at the tip
[06:06:07] <archivist> want to leave a hole?
[06:06:12] <ReadError> yea
[06:06:50] <archivist> you may get away with a collet and a hand rest only
[06:08:03] <archivist> this guy has a roller https://www.youtube.com/watch?v=um-biLfru-c
[06:12:10] <archivist> so a ball race in a tool holder pressed against the tube to form the shape
[06:17:56] <ReadError> there has to be something easy for this
[06:18:04] <ReadError> like a bowl type thing
[06:18:07] <ReadError> jam tube in
[06:19:28] <archivist> not sure that will work but http://www.ebay.co.uk/itm/37-pc-Doming-Block-and-Punch-Set-made-of-Steel-Dapping-/290516481067
[06:19:54] <archivist> clockmakers use that for doming hand washers
[06:21:12] <archivist> your problem is other parts of the tube will deform as much as the end possibly
[06:21:38] <archivist> depends on grip, support etc
[06:22:26] <archivist> and how many you want to make
[07:34:56] <ketul> I am interested for New realtime kernels in LinuxCNC
[07:35:15] <ketul> can anyone help for getting started
[07:45:22] <SpeedEvil> What do you maen by that?
[07:47:51] <archivist> gsoc student
[08:17:48] <jthornton> anyone have a clue what this means on wheezy http://imgbin.org/index.php?page=image&id=22823
[08:19:14] <archivist> did you say yes to an OS upgrade
[08:19:36] <jthornton> not that I know of
[08:19:53] <jthornton> it shows up on both of my wheezy computers now
[08:20:20] <jthornton> kinda hard to answer two questions with a yes or no
[08:20:43] <archivist> I hate upgrades and the breakages
[08:23:04] <jthornton> it's a trick question... do you want to do a or b yes or no?
[08:24:09] <archivist> I suppose it is asking you have already said yes to upgrade now shall we chuck stuff or not
[08:28:36] <jthornton> now I get this http://postimg.org/image/7h0840vbn/
[08:30:36] <archivist> I suppose they are also admitting upgrading is not safe
[08:31:03] <jthornton> dunno, never had this problem before
[08:36:58] <SpeedEvil> Upgrading is never safe.
[08:37:05] <SpeedEvil> Downgrading is never safe.
[08:37:11] <SpeedEvil> Staying static is never safe.
[08:37:29] <jthornton> lol
[08:48:19] <pcw_home> Thats the standard upgrade message but in Debian its designed to make you queasy
[09:35:39] <Tom_itx> how is it an upgrade if it doesn't remove packages or install new ones?
[09:37:23] <pcw_home> its upgraded your confusion
[09:37:45] <Tom_itx> windows just does it and makes you regret it
[09:37:58] <pcw_home> :-)
[09:39:31] <archivist> a few months ago I did a win7 laptop that had no updates for years, took best part of a couple of days
[09:42:09] <pcw_home> Yeah my ebay laptop had a fresh (and relatively ancient) win7 installation, also took days to get up to date
[09:44:08] <archivist> reboot hell :)
[09:44:47] <pcw_home> then update-grub busted the MBR on the windows drive
[09:48:41] <archivist> the reason the upgrades had never been done was an original intel driver(not even needed) being incompatible after it went from win98 to win7
[09:56:18] <ssi> http://www.recilaser.com/en/newsInfo/ba9e706849167e770149177de8e00e86.htm
[09:56:18] <ssi> hah neat
[10:12:12] <ssi> thanks for the info, reci:
[10:12:12] <ssi> Do not clean the exterior surface of the output widow mirror with tools such as tampon; otherwise the output power will be seriously affected.
[10:12:35] <ssi> If the methods above don't work effectively, it is necessary to go after the professional workers to
[10:12:39] <ssi> use tampon with alcohol to clean the mirror surface from middle to edge. The best solution is to
[10:12:42] <ssi> prevent the window from being polluted.
[10:12:46] <ssi> apparently professional workers are the only ones qualified to wield a tampon
[10:13:49] <archivist> I have never wielded a tampon when cleaning a window
[10:15:49] <ssi> perhaps you should try it
[10:15:54] <ssi> but only if you are professional worker
[10:19:32] <archivist> I do odd jobs for a window company, does that make me a professional :)
[10:19:37] <ssi> yep
[10:20:36] <archivist> but we use elephant sized bog roll
[11:49:23] <furrywolf> I hate batteries.
[11:51:49] <_methods> only if you use a tampon
[11:53:07] <furrywolf> ... is that to me, or did I walk in on something? lol
[11:54:55] <furrywolf> one of my L16s has decided to become 4V instead of 6V, so now I can't run large loads or the inverter will trip on undervoltage.
[12:00:36] <_methods> yeah ssi is trying to become a professional worker
[12:02:52] <renesis> cant use tampon until pro
[12:05:17] <SpeedEvil> furrywolf: I occasionally wonder about simple lead-acid cells in jars, with a little reprocessor that takes the cell contents, melts, adds CO/... and out pops lead and acid, which go into a new battery
[12:06:08] <furrywolf> I have a feeling, though I've never done the math, that the energy input needed to make a lead-acid battery exceeds the energy it stores over its life...
[12:07:24] * furrywolf isn't sure how tampons relates, so goes back to posting a wanted ad on craigslist for batteries
[12:09:32] <renesis> because ur a girl and tampons are for girls
[12:10:17] <renesis> not enough tampons in STEM fields
[12:10:24] <SpeedEvil> It was following on from archivists comment that he uses elephant-sized bog-roll
[12:11:14] <renesis> which followed on cleaning lasers with tampons is only allowed by certified professions
[12:11:31] <renesis> do not try this, with tampons, at home
[12:11:47] <furrywolf> lol
[12:12:06] * furrywolf is soft and fluffy
[12:14:43] <furrywolf> I could re-arrange my batteries to not use this one, but it'll leave me with pretty crap capacity, and this battery does still store a decent Ah, it just self-discharges in a couple days... not sure which is worse.
[12:15:39] <archivist> dead batteries are dead, replace
[12:15:59] <furrywolf> do I want ~160Ah with a cell that self-discharges, or do I want ~100Ah that stores reliably? heh
[12:17:46] <furrywolf> I might be able to toss a couple semi-dead marine deepcycles in parallel with some of the re-arranged batteries to make up some of the capacity... probably the best option.
[12:18:46] <furrywolf> archivist: replacing with new batteries is expensive
[12:20:26] <Cromaglious> furry research high frequency battery rejuvenators... the cut the lead sulfication on the plates and get some of it to reconvert to klead and back to sulphuric acis and the rest sublimes to the bottom of the batter, so no internal shorts (self discharge)
[12:21:31] <furrywolf> sulfation doesn't cause internal shorts. the exact opposite, in fact. the sulfate is an insulator, which results in reduced capacity.
[12:22:06] <furrywolf> internal shorts are caused by too much crap at the bottom of the battery, or swollen, buckled, crumbling, disintegrated, or otherwise failed plates.
[12:24:12] <furrywolf> also, my experience is those things are all utterly useless, and the best cure for sulfation is an extended overcharge with a cheapo unregulated transformer+rectifier charger, keeping the water topped up.
[12:24:55] <furrywolf> if you read the instructions for many of them, you're supposed to use them while also charging the battery continually... and guess which part is actually being helpful? heh
[12:26:06] <SpeedEvil> furrywolf: I've heard simply opening them up, and actually properly soldering a shorting bar across them. (lead of course)
[12:26:40] <furrywolf> that would fix a bad contact... not going to do much for any other failure.
[12:26:42] <SpeedEvil> Sulphation can also cause plate geometry changes as I understand it, which can also flake bits off
[12:26:55] <SpeedEvil> furrywolf: Or a partially shorted cell. For some values of 'fix
[12:27:11] <Cromaglious> so if you automate the charge and discharge of a battery you can bring it back?
[12:27:32] <SpeedEvil> Cromaglious: In limited cases, yes
[12:27:43] <SpeedEvil> If there have not been certain classes of physical damage
[12:27:57] <SpeedEvil> - you're not going to remove sludge from the bottom of the battery, or ...
[12:28:33] <archivist> you can pressure wash and refill acid
[12:29:27] <furrywolf> hrmm, radio shack is apparantly selling their parts drawers. do I need a nice sliding drawer storage thingy?
[12:30:14] <SpeedEvil> You could always make one out of old batteries :)
[12:31:14] <SpeedEvil> Sounds worth checking out at least
[12:33:16] <CaptHindsight> sad that the best stuff at Radio Shack is their cabinetry and show cases
[12:34:34] <SpeedEvil> :/
[12:35:03] <SpeedEvil> Well - the internet prettty much killed the remnants of the electronics retail shop.
[12:35:21] <SpeedEvil> Those that hadn't gotten eaten by large catalog stores.
[12:35:49] <furrywolf> I think idiotic management killed them... like having 95% of the store be stupidly overpriced cell phone accessories that no one would ever buy. cigarette USB power adapters for $20, etc.
[12:35:49] <CaptHindsight> now i have to order a fuse, led or 4 pin molex rather than drive 20 minutes to get one
[12:36:02] <CaptHindsight> yes, I agree
[12:36:24] <SpeedEvil> Problem is at some point you lose thefootfall.
[12:36:25] <CaptHindsight> they should have sold the top 200 electronics items on alibaba or similar
[12:36:27] <furrywolf> they had a good idea with their maker-oriented remodel... but too late.
[12:37:00] <furrywolf> being able to take your stl file down to the local radio shack and print it would have brought a decent number of people in I suspect.
[12:37:06] <SpeedEvil> In principle radio shack could have had an awesome maker platform - but a couple of years too early
[12:37:16] <SpeedEvil> 3d hasn't properly hit yt
[12:37:17] <SpeedEvil> et
[12:37:31] <CaptHindsight> of like Fastenal, have several regional hubs and what they dont have today, it's at the store the next day
[12:37:38] <Cromaglious> I ordered resistors online, thursday, received them from Ohio Saturday
[12:37:38] <furrywolf> the one that's selling all the fixtures was starting their maker remodel... didn't get it finished.
[12:38:15] <CaptHindsight> they could have sold unlocked everythings
[12:38:17] <furrywolf> CaptHindsight: I have never ordered anything from fastenal. every time I go in there, the high prices, high shipping charges (even between stores), and crap service have always resulted in my leaving.
[12:38:23] <CaptHindsight> phones, tablets, netbooks etc
[12:39:16] <furrywolf> I wanted some little screws, I think they were 6-40 or something... they wanted something like 15 cents a screw, would only get me a bag of 50, and wanted $5 to ship it from the hub to the store, a week later.
[12:39:46] <CaptHindsight> my hub is ~300 miles away and it gets here the next day
[12:39:53] <furrywolf> they couldn't get the metric bolts I needed, period.
[12:39:56] <CaptHindsight> they run a truck every night
[12:40:01] <furrywolf> while a local store was able to
[12:40:20] <furrywolf> I can't remember all the times I've tried them, but I've never left with anything.
[12:40:27] <CaptHindsight> Radio shack could have had 10-20 regional warehouses with all the top selling China gadgets
[12:40:57] <CaptHindsight> the stores could have been for local pickup and warranty
[12:41:09] <CaptHindsight> also to demo new stuff
[12:41:38] <CaptHindsight> anti-apple products
[12:41:59] <CaptHindsight> the could have debunked the over priced iCrap
[12:42:44] <furrywolf> pissing apple off is bad when you're large enough to be worth suing.
[12:42:57] <CaptHindsight> but they wanted to make the majority of their income on cell plans
[12:43:31] <furrywolf> I think they could have done well with the maker stuff... trying to pretend to be a mini-hackerspace, etc...
[12:43:58] <CaptHindsight> with a chain of stores with overheads much higher than a kiosk at the mall
[12:44:23] <furrywolf> malls suck. anything in a mall I avoid.
[12:44:28] <SpeedEvil> Plus - with a one-man-band - staffing isn't an issue
[12:46:24] <furrywolf> the weather is being weird today... feels like a storm. it's getting windy, but the humidity is dropping to record lows... and 29.7 barometer isn't good either...
[12:46:51] * furrywolf checks what the nws has to say
[12:47:29] <CaptHindsight> dry heat is good for arthritis
[12:47:41] <furrywolf> "Models are in decent agreement indicating that this
[12:47:42] <furrywolf> band will be heavier (periods of moderate to locally heavy rain)"
[12:47:45] <furrywolf> yay.
[12:48:34] <furrywolf> "Gale Warning from 10 am this morning to 5 PM PDT this afternoon" redundancy, anyone?
[12:49:31] <furrywolf> meh, I can't run the microwave without firing up the genny. I hate batteries.
[12:49:35] * furrywolf eats bagels and lox instead
[12:50:41] <furrywolf> I need to make a trip to the dump today, go to the hardware store, and shuffle batteries around... probably eat, then dump, try to get it done before the rain hits.
[12:52:16] <SpeedEvil> Question is - can you pick up new batteries at the dump :)
[12:53:32] <furrywolf> no
[13:14:34] <furrywolf> wtf?! I've apparantly been blocked from craigslist, by IP.
[13:15:14] <SpeedEvil> Are you on a shared IP?
[13:19:53] <furrywolf> no
[13:20:31] <Jymmm> More than likely by subnet, not individual IP
[13:30:58] <furrywolf> why would you do a subnet block on static IPs?
[13:32:11] <CaptHindsight> maybe they think the spammers (or whatever they have a beef with) have a block of ip
[13:32:55] <SpeedEvil> Or a dynamic IP kill
[13:33:02] <SpeedEvil> asuming it's dynamic rather
[13:33:10] <SpeedEvil> maybe some pople on that subnet have dynami
[13:33:11] <SpeedEvil> c
[13:34:39] <CaptHindsight> some spammers are very hands on, I get requests from the same ip at times with captchas that I can hardly read in blocks of 10-100
[13:35:21] <CaptHindsight> same ip block, different username and different email address
[13:35:22] <FinboySlick> furrywolf: There's no way to know that your IP is static from the craiglist end.
[13:36:48] <renesis> also if someone on the same block hit from two IP, its safest
[13:36:55] <renesis> maybe someone just doesnt like you furrywolf
[13:37:36] <ReadError> mcmaster bans you
[13:37:40] <ReadError> if you browse too much ;/
[13:37:46] <ReadError> maybe similar ?
[13:37:47] <renesis> no shit?
[13:37:50] <ReadError> ya
[13:37:55] <renesis> without buying?
[13:37:57] <ReadError> had to call them and be like 'hey bro unban me'
[13:37:58] <renesis> what is too much
[13:38:03] <ReadError> nah dude i had shit in my cart
[13:38:08] <ReadError> and couldnt even checkout
[13:38:19] <renesis> how long were you browsing?
[13:38:24] <renesis> like two weeks? two hours?
[13:38:31] <ReadError> less than an hour
[13:38:54] <renesis> thats really weird ive worked on BOM shit and been there all day
[13:39:14] <ReadError> well i was sourcing a lot of various stuff
[13:39:17] <ReadError> and using the search
[13:39:52] <renesis> they they finally overhaul their site to make search useful and direct linking possible
[13:40:03] <renesis> and now they get mad when people use it?
[13:40:51] <renesis> maybe you searched to quick and they thought you were a DOS attack because stupid security script parameters
[13:42:56] <archivist> or thought it was a bot scraping the prices
[13:48:34] <renesis> yeahs its maybe how you were browsing not how much
[13:48:38] <renesis> but thats dumb
[13:51:12] <furrywolf> I did just do several quick searches in a row...
[13:51:38] <Jymmm> furrywolf: they have no idea whats static or dynamic, if they're gettng hit by multiple ips in the same subnet, block the subnet
[13:52:05] <Jymmm> and it's not viewing, it's posting they usually block on.
[13:52:47] <Jymmm> so look for posts in your area tha look like spam and you found the bastard
[13:59:33] <furrywolf> kinda hard to look for posts when you're blocked. :P
[14:00:06] <Jymmm> furrywolf: You're blocked from VIEWING or POSTING ?
[14:00:59] <XXCoder> furrywolf: got any vpn?
[14:03:08] <furrywolf> Jymmm: anything. loading craigslist.org.
[14:03:36] <furrywolf> yes, I do use a vpn... to a static IP. my isp doesn't let you use the web in a functional fashion.
[14:03:58] <alex4nder> you in prison?
[14:03:59] <XXCoder> heavy filters or what? not sure what you mean funcional way
[14:06:08] <Jymmm> furrywolf: Be nice and email help@craigslist.org with you IP letting them know you can't view
[14:08:37] <FinboySlick> furrywolf: Maybe craigslist blocked known VPN providers.
[14:09:25] <Jymmm> Aw fuck, the new thunderbird has poofiness bullshit.
[14:10:19] <Jymmm> Puts up a "please wiat" spinning icon every time you switch folders, even if you've already been to one.
[14:12:06] <furrywolf> XXCoder: virgin "improves my browsing experience" by downsampling all images to jpeg quality 10 or so, blocking random things, blocking video, fucking with DNS results, and injecting their javascript into anything that even resembles a html file.
[14:12:34] <furrywolf> they intercept and proxy anything that looks like a http connection.
[14:13:35] <furrywolf> most non-trivial websites stop working due to the various things they "improve", especially any sites that combine javascript and images. which is, you know, most of them these days.
[14:13:47] <furrywolf> for example, ebay stops working.
[14:14:56] <furrywolf> so, to have functional web browsing on virgin, you need to tunnel everything somewhere else... in my case, my linode. you can't even use virgin's dns, you have to use your own. and they like intercepting dns queries too, so you have to tunnel your own dns even...
[14:18:31] <SpeedEvil> Can't you turn that off?
[14:20:25] <furrywolf> no
[14:21:30] <skunkworks> http://www.machsupport.com/forum/index.php/topic,29442.msg205846.html#msg205846
[14:21:32] <furrywolf> bbl, off to the dump and the hardware store.
[14:23:49] <pcw_home> to the dump
[14:23:50] <pcw_home> to the dump
[14:23:52] <pcw_home> to the dump dump dump
[14:25:14] <Cromaglious_> weeee
[15:02:05] <Cromaglious_> ok, installing sketchup make 2014, then I can install phlatscript sketchUcam I think it's called now
[15:31:52] <t12> so i'm trying to find a cheap single phase 440hz 115v power supply
[15:31:54] <t12> er 400hz
[15:33:38] <t12> think i can just use 2 3phase vfd outputs
[15:34:07] <t12> maybe hard to actually get 115 out of that
[15:42:23] <zeeshan> what kind of load?
[15:51:56] <t12> little motor for a gyro
[15:52:01] <t12> from wwII aircraft junk
[15:52:12] <t12> i think its a 2ph motor, with phase shift caps next to the motor
[15:53:02] <t12> http://www.ebay.com/itm/Static-Inverter-12-VDC-400-VA-120-VAC-400-Hz-Fan-Cooled-/291407400431?pt=LH_DefaultDomain_0&hash=item43d93c0def maybe this
[15:53:48] <t12> the motors in these systems are crazy
[15:53:57] <t12> like a 3ph motor, with a built in 3ph synchro for analog servo i guess?
[15:54:07] <t12> but tiny tiny
[15:54:10] <t12> like half a coffee cup
[16:04:32] <XXCoder> damn
[16:04:45] <XXCoder> furry have really bad isp
[16:31:49] <XXCoder> hey fur
[16:31:56] <XXCoder> damn your isp sounds really bad
[16:32:00] <furrywolf> batteries shuffled so I have a 24V instead of 22V bank again... but at even less capacity.
[16:32:08] <XXCoder> makes comcast around here seem tame
[16:32:20] <XXCoder> heard of tor browser though?
[16:32:51] <furrywolf> ah, yes, tor... let's redirect my browsing through 20 hops all overloaded with people running bittorrent to an exit node that's probably blocked everywhere!
[16:33:09] <XXCoder> it's surpising effective
[16:34:42] <furrywolf> now I need to decide if I want to run the genny a bit to get the overall SOC up and try to equalize the now-very-mismatched strings...
[16:37:45] <XXCoder> plan to rebuild batteries or?
[16:37:55] <furrywolf> scrap.
[16:38:06] <furrywolf> there's no rebuilding pasted plate batteries.
[16:38:19] <XXCoder> make homebrew batteres? heh
[16:38:26] <XXCoder> one thats rebuildable
[16:38:34] <furrywolf> I do plan on trying to repair my NiFe one of these days, but that takes money.
[16:38:59] <furrywolf> I have 40 300Ah NiFe cells that need an electrolyte change.
[16:39:37] <XXCoder> yea need money
[16:40:32] <furrywolf> around $1000
[16:41:45] <XXCoder> https://www.youtube.com/watch?v=p0K41mQVMJw probably fake but jeez
[16:44:25] <furrywolf> 200lbs of KOH, 10lbs of LiOH, 60+ gallons of distilled water for final fill, another 60+ gallons to rinse the old crud out, vats suitable for mixing such chemicals in,...
[16:44:40] <XXCoder> wonder if you could distall water
[16:44:52] <XXCoder> cut that expense in least
[16:44:59] <furrywolf> I plan to RO+DI water.
[16:45:26] <XXCoder> ahh not too bad then
[16:45:51] <XXCoder> https://www.ehow.com/how_5700913_make-potassium-hydroxide.html
[16:46:27] <XXCoder> wood ashes -> KOH
[16:46:40] <furrywolf> yes, you do realize every one of those will cost a lot more than just buying it, right?
[16:46:54] <furrywolf> getting wood ashes to sufficient purity is not easy.
[16:47:12] <furrywolf> in particular, carbon is very bad for nife batteries. want to guess what a lot of ashes is?
[16:47:27] <XXCoder> oh dunno carbon? lol yeah
[16:47:57] <furrywolf> this isn't making soap. batteries are a little more picky about impurities. :P
[16:48:38] <furrywolf> also, interestingly, firefox is rejecting ehow's ssl cert.
[16:49:06] <XXCoder> probably due to man in middle attack by virgin
[16:49:09] <XXCoder> its fine here
[16:49:20] <furrywolf> no, I proxy everything to my linode, remember? heh
[16:49:33] <XXCoder> ahh yea somethings going on then
[16:49:36] <furrywolf> first time I've ever seen firefox bitch about anything other than small cites with self-signed certs.
[16:49:42] <furrywolf> sites
[16:52:12] <XXCoder> fuk that site. I hate sites that use billion domains scripts to work.
[16:52:27] <XXCoder> Found site that shows how make KOH from iodine and possium
[16:52:36] <furrywolf> "This website does not supply ownership information." seems to be firefox's main complaint
[16:52:45] <furrywolf> right, let's make something cheap from two more expensive things!
[16:52:58] <t12> lol
[16:53:04] <t12> stereo amp + stepup transformer appears to work well
[16:53:16] <XXCoder> just bit surpised it would be more money
[16:54:24] <furrywolf> t12: for what? for esex, just buy a real power box. :P
[16:54:33] <XXCoder> so you cant make those 2 chemicals without getting em cheaper as is?
[16:57:59] <furrywolf> potassium hydroxide is prepared directly from mined materials, and is relatively common, used in vast quantities, and is easy to store and transport. pure potassium metal is rare, dangerous, ... and produced by electrolysis of potassium hydroxide. :P
[16:58:55] <XXCoder> I guess any pure form of very reactive material is pretty rare
[16:59:16] <XXCoder> aluminium is bit strange as its really reactive but it protects itself with very hard oxide
[16:59:41] <XXCoder> odd that white powder is rust of alum rust. :P
[17:00:19] <furrywolf> potassium will try to protect itself with oxides too... just those oxides happen to be quite explosive. and catches fire on contact with water, and all sorts of other fun things.
[17:00:42] <XXCoder> yeah and iron oxide sucks lol
[17:00:50] <XXCoder> odd one is tin pest
[17:01:11] <XXCoder> tin pest helps make more of tin pest
[17:01:27] <XXCoder> so where do first tin pest come from lol
[17:01:33] <XXCoder> you know?
[17:02:13] * furrywolf re-reads earlier sentance... say small sites with self-signed ssl certs ten times real fast.
[17:02:46] <XXCoder> said it 10 times no problem, but then I didnt use togue or mouth in general lol]
[17:03:53] <furrywolf> hrmm, you're non-speaking, not just non-hearing? didn't know that. I'll wait for someone else to say it ten times real fast. :P
[17:04:06] <XXCoder> I could speak it if I knew how
[17:04:14] <XXCoder> voice works fine
[17:05:36] <XXCoder> there is such thing as handtwisters
[17:05:39] <XXCoder> but its rare
[17:05:58] <XXCoder> I found one word but forgot what word it was aw
[17:08:27] <XXCoder> It's toothbrush! It's drinking fountain! It's magical floating toothbrush! https://i.chzbgr.com/maxW500/6325196288/h622F5895/
[17:09:32] <furrywolf> it's a 3d rendering?
[17:09:37] <XXCoder> yeah
[17:09:52] <XXCoder> pretty good one, besides magic floating part
[17:10:02] <furrywolf> physics do not apply to renderings. :P
[17:10:11] <XXCoder> yup lol
[17:10:45] <furrywolf> also, while converting a large volume of water falling a short distance to a small volume of water shooting a high distance is quite possible, I don't think that device does it. :P
[17:11:12] <XXCoder> dunno
[17:11:19] <XXCoder> right shape funnel
[17:11:38] <XXCoder> likely real world it'd be shorter shoot up
[17:12:03] <furrywolf> for one, the waste percentage isn't nearly high enough - there's only a few dribbles falling off the bottom of the toothbrush, while twice the height would suggest at least half the input water would need to be dumped
[17:12:37] <XXCoder> good thing rendering dont need to worry about physics eh
[17:13:17] <furrywolf> these are basic things any redneck should know. :P
[17:13:40] <furrywolf> when you build a ram pump to get water up to your house from your stream, you need to know how much water you'll get vs how high you are...
[17:14:24] * SpeedEvil imagines a redneck ram pump to involve a wheel and a male sheep.
[17:14:55] <furrywolf> no, it involves leaky check valves and rusty pipe fittings
[17:14:59] <renesis> what did i just walk into
[17:15:10] <renesis> this is weirder than laser tampons
[17:15:19] <XXCoder> https://www.lhup.edu/~dsimanek/museum/gearcoil.gif another impossible animation
[17:15:24] <SpeedEvil> Ram pumps are rather cool.
[17:15:51] <SpeedEvil> I do like the spiral coil of pipe pump too
[17:16:10] <renesis> xxcoder: why is that impossible?
[17:16:17] <XXCoder> free energy
[17:16:32] <renesis> what
[17:16:40] <renesis> no
[17:16:49] <renesis> the spring gets hotter and the energy goes away
[17:17:00] <XXCoder> exactly, it would stop
[17:17:10] <XXCoder> its from site that says it will rotate forever
[17:17:16] <renesis> but its a cool animation that doesnt break reality
[17:17:22] <renesis> oh
[17:17:25] <renesis> well theyre dumb
[17:17:26] <SpeedEvil> Err
[17:17:32] <renesis> but they can make cool gifs
[17:17:33] <furrywolf> is it being advertised as a free energy device?
[17:17:33] <SpeedEvil> Surely it's nothing to do with hotter
[17:17:34] <furrywolf> ah
[17:17:39] <SpeedEvil> It's to do with balanced torque
[17:17:43] <SpeedEvil> It never moves
[17:17:49] <XXCoder> yup
[17:17:57] <zeeshan> lol it never moves
[17:17:58] <zeeshan> haha
[17:18:03] <furrywolf> I was assuming one of the shafts was being driven...
[17:18:05] <renesis> i figured the gears were driven
[17:18:20] <XXCoder> http://www.besslerrad.de/Bhask.GIF
[17:18:23] <renesis> and someone like, jumped the spring a few teeth
[17:18:24] <XXCoder> now thats fun
[17:18:46] <renesis> thats neat
[17:18:49] <XXCoder> "outbalanced" wheels used to vbe common
[17:18:54] <XXCoder> and still nonworking
[17:18:58] <renesis> friction, obviously
[17:19:07] <renesis> but yeah it looks cool
[17:19:14] <XXCoder> im sure you all has machinist handles that has 3 handles
[17:19:15] <renesis> needs more frames
[17:19:23] <renesis> or faster resolution
[17:19:38] <renesis> revolution
[17:19:40] <XXCoder> hang it and it will not "correct" balance (assuming connected to firctionless bearing exactly at center and balanced)
[17:19:49] <furrywolf> you can make one of those that appears to work well enough to fool laypeople if you fill it with propane or another gas that you can make do a phase change when one side is heated
[17:20:18] <XXCoder> furrywolf: theres real one that works, but it uses heat source to send fluid to other side
[17:20:27] <XXCoder> aka thristy bird method
[17:20:39] <XXCoder> (anyone ever seen one of those thristy bird toys? lol)
[17:20:45] <furrywolf> yes
[17:20:45] <renesis> ha ya
[17:23:03] <furrywolf> ... lol. the top news item on wikipedia is a penis transplant.
[17:23:14] <XXCoder> not surpised
[17:23:19] <XXCoder> there was recent first
[17:23:21] * furrywolf tries to decide if it's actual news or trolling by someone with admin access
[17:23:30] <XXCoder> and its done in africa
[17:24:52] <XXCoder> http://www.packratworkshop.com/pics/minto1a.jpg I cant find later version
[17:27:24] <XXCoder> nice article on wally wonder wheel http://www.motherearthnews.com/nature-and-environment/solar-wheel-zmaz76jaztak.aspx
[17:27:37] <XXCoder> not surpised its flawed but basically works
[17:28:31] <furrywolf> it's just a heat engine... no laws of thermodynamics broken.
[17:28:38] <XXCoder> yeah
[17:28:56] <XXCoder> it does look like one of those ricious "overbalance" wheels but actually works,
[17:29:33] <furrywolf> I've always wanted to build a fake perpetual motion machine as a garden water feature... have a chain bucket pump lifting water up and dumping it onto the top of a waterwheel on the same shaft... and a hidden electric pump to supply the extra water to make up for losses.
[17:29:59] <XXCoder> I just want magic floating facuet that pours water at full speed
[17:30:06] <XXCoder> trick is too simple
[17:30:34] <furrywolf> not sure what you mean
[17:30:57] <XXCoder> http://cdn.instructables.com/FME/87HY/H1JUHKVR/FME87HYH1JUHKVR.LARGE.jpg
[17:31:02] <XXCoder> its real
[17:31:42] <FinboySlick> Pretty clever fountain.
[17:32:03] <furrywolf> hrmm. it's very light, hollow, counterbalanced by a very dense weight on the very tip of the spout, and supported by a jet upwards in the middle of the falling water?
[17:32:20] <XXCoder> hard clear plastic tube inside
[17:32:24] <XXCoder> it pushes water up
[17:32:31] <XXCoder> and holds tap up
[17:32:35] <furrywolf> bah, that's cheating.
[17:32:50] <furrywolf> my design would actually be floating. :P
[17:33:08] <furrywolf> would need some fancy engineering to ensure dynamic stability though...
[17:33:09] <XXCoder> yeah. you cant see it flowing upwards since downwards is covering it lol
[17:33:27] <XXCoder> fancy indeed
[17:34:07] <furrywolf> I saw a picture of a firehose jetpack once...
[17:34:25] <XXCoder> hmm not unique enough http://3.lushome.com/wp-content/uploads/2013/03/water-fountains-design-ideas-floating-tap-fountain-1.jpg
[17:34:45] <XXCoder> it does not pump enough water so can see support
[17:34:58] <XXCoder> add 2x ore pumps stat!
[17:35:37] <furrywolf> I could design one with no hidden support...
[17:35:52] <XXCoder> that'd be hell of trick. do it :)
[17:35:59] <furrywolf> too much work. :P
[17:37:27] <Cromaglious_> ok 7 tooth 21" gear cut out
[17:37:42] <XXCoder> lol ok
[17:37:50] <XXCoder> probably be a issue if power went out
[17:38:05] <furrywolf> you'd need a strong jet upwards, and a very very light, balanced "tap". to make it stay centered and level, you'd need to design a funky shaped reaction surface... maybe aiming into a hollow cylinder, which will self-correct angular rotation, with a funnel shape so any horizontal error will result in a corrective force...
[17:38:21] <furrywolf> it'd probably still end up going up too high for the corrective forces to work, then tumbling.
[17:39:09] <FinboySlick> furrywolf: Not much to prevent it from spinning around the Z axis.
[17:39:21] <furrywolf> you'd might need to depend on surface tension around the outside of a cylinder, and other hydrodynamic effects...
[17:39:26] <furrywolf> FinboySlick: that's a feature.
[17:39:28] <XXCoder> that'd be extra surreal
[17:39:40] <moorbo> Do you guys know of a place where a person can read about fastening
[17:39:42] <XXCoder> though maybe fins inside that funnel
[17:39:59] <Nick001-shop> How do I get stepper-xyxa into the new debian Linuuxcnc? It doesn't seem to load up as many configurations as Ubuntu did.
[17:40:12] <FinboySlick> moorbo: Depending on the type of fastening you're talking about, 50 Shades of Grey might work.
[17:40:13] <moorbo> I hear most of machining is just keeping your piece in one place.
[17:40:22] <furrywolf> the obvious answer is to use the incoming water jet to spin a small turbine to run a small uC to activate a variety of hidden control surfaces and reaction control jets. :P
[17:40:25] <moorbo> FinboySlick: thanks for uselessness.
[17:41:33] <FinboySlick> moorbo: It's typically referred to as workholding.
[17:41:50] <furrywolf> I haven't read 50 shades of grey, but from everything I hear, it's fucking awful, both as a story and as an introduction to bondage.
[17:42:05] <XXCoder> yea it used to be twight fanfiction
[17:42:08] <Deejay> gn8
[17:42:09] <XXCoder> so not surpised
[17:42:51] <furrywolf> "Although we sincerely wish otherwise, we've just spent $12,000 proving that the Minto wheel isn't really a practical solar-powered engine" lol
[17:42:52] <FinboySlick> furrywolf: I needed an popular reference for the joke to work.
[17:44:08] <jdh> I have a rigid robot arm end effector. I want it to be not-so-rigid so that it can give a little when inserting something. What is the proper terminology for a wobbly joint for that?
[17:44:23] <iceberg303> Noob to the CNC and I have someone helping me but they use commercial software Mach3. I'm looking for controller that can be sued with both Mach3 and LinuxCNC. That said I'm having trouble understanding whic parallel port boards will work and Im looking at this setup: https://buildyourcnc.com/item/electronicsAndMotors-3axis-100-elcombo
[17:44:28] <furrywolf> jdf: erectile dysfunction
[17:44:49] <jdh> I'm sorry, have you consulted a urologist?
[17:45:12] <XXCoder> urologist would have issue with furrywolf heh
[17:45:14] <furrywolf> iceberg303: linuxcnc will work with all parallel breakout boards, as it's very configurable.
[17:45:21] <FinboySlick> jdh: I'd go for flexible coupling, though I don't think that's entirely accurate.
[17:45:30] <iceberg303> Thanks!
[17:46:14] <furrywolf> the one I'm using with linuxcnc was sold on ebay as a "mach3 breakout board"... linuxcnc lets you specify which pins are used for what, in any configuration.
[17:46:29] <XXCoder> http://www.thescienceforum.com/personal-theories-alternative-ideas/27356-why-i-wanst-taught-about-minto-wheel-thermodinamics.html
[17:46:40] <FinboySlick> iceberg303: You can have linuxcnc use the same pins for the same singals as mach3, the trickier part will be finding a pc with good realtime behavior.
[17:46:48] <furrywolf> what directions do you want give? how stiff? something like a rubber vibration isolation bushing might do the job...
[17:47:17] <jdh> I want it to give in YZ more or less
[17:47:33] <jdh> and a little X
[17:47:58] <jdh> inserting a rod into a hole. It needs to seat fairly firmly
[17:48:29] <iceberg303> will a core2 duo at 2.6Gha work my understanding was that it would
[17:48:34] <jdh> I'd like to be able to swap out the part with the hole without resetting teh arm
[17:48:51] <furrywolf> make a small metal box that's large in x and small in y and z, insert it into a cube, fill with 2-part rubber of appropriate density?
[17:49:08] <XXCoder> furrywolf: wonder if 3 of those, with 1/3 rotation offset, would help make rotation smoother
[17:49:27] <jdh> that might work. the rod is held with a pnuematic V gripper
[17:49:38] <furrywolf> iceberg303: it has more to do with the randomness of individual manufacturers, bios versions, on-board hardware, etc, than cpu speed. an old pentium 2 will run linuxcnc great.
[17:49:53] <iceberg303> ok
[17:52:12] <FinboySlick> iceberg303: You can boot off the linuxcnc livecd, run a latency test and use the machine havily.
[17:52:38] <FinboySlick> You want to keep your latency numbers below 15000 I'd say.
[17:53:46] <pcw_home> Core 2 Duos are normally quite good
[17:54:08] <Cromaglious_> furrywolf: home many relay's are on your board?
[17:54:29] <Cromaglious_> how many
[17:54:32] <furrywolf> one, and I'm not currently using it. (just turning the spindle on manually)
[17:54:44] <Cromaglious_> ahh you and I have the same board
[17:54:54] <Cromaglious_> i already fried on.. Got 2 more
[17:54:57] <Cromaglious_> one
[17:56:06] <XXCoder> https://www.youtube.com/watch?v=NhFKHTdNPt4 now thats interesting lol
[17:56:21] <XXCoder> design varation, I think works better and can pack even more in
[17:56:38] <furrywolf> my first one exploded.
[17:56:41] <FinboySlick> XXCoder: Shape memory alloys?
[17:57:01] <XXCoder> no, it has low temperate fluid inside
[17:57:07] <furrywolf> also, I don't see how you can conclude we have the same board based only on us both having boards with only one relay. I suspect there's more than one board with only one relay. :P
[17:57:08] <XXCoder> heat pumps it to other side
[17:57:21] <FinboySlick> OK.
[17:57:41] <XXCoder> its not best idea for power generating but I might do it for fun
[17:57:52] <XXCoder> its not like I actually need it
[17:59:10] <furrywolf> someone I know has a very neat device based on heating fluids... it's a tracker for a solar panel array. it has two tubes/tanks on the outside edges of the array, with some shades to only pick up sun from certain angles. as the sun moves, if it's not aimed centered, one cools and the other heats, causing the panel to tilt towards the sun until they're balanced again.
[17:59:39] <XXCoder> furrywolf: I saw another that literally use solar panels to center solar panels
[17:59:46] <zeeshan> http://i.imgur.com/xDVSBd9.png
[17:59:48] <zeeshan> lathe enclosure nightmares
[17:59:49] <zeeshan> lol
[17:59:51] <XXCoder> the controlling panels is small, enough to power motor
[18:00:05] <XXCoder> motor turns based on which side gets more power
[18:00:44] <furrywolf> http://www.motherearthnews.com/diy/solar-tracker-zmaz77ndzgoe.aspx similar to that
[18:01:01] <XXCoder> http://www.mdpub.com/suntracker/
[18:01:21] <XXCoder> wow thats nice
[18:01:29] <XXCoder> basically solid state and run forever
[18:01:39] <furrywolf> he says it works great, but takes about a half hour of cold morning sun before it aims into the sun from the nighttime neutral position
[18:02:12] <XXCoder> half hour hmm bit slow but decent
[18:02:29] <Cromaglious_> furrywolf: mine also is labeled Mach3 break out board
[18:02:42] <Cromaglious_> Mach3 battery Operated boyfriend
[18:02:58] <furrywolf> the "neutral" position is where a fixed non-tracking array would be, so for that half hour you're just getting the same output you would if you had no tracker.
[18:03:09] <XXCoder> yeah not bad
[18:03:57] <furrywolf> Cromaglious: does it look like http://fw.bushytails.net/bbcaps/bbcap01.jpg ?
[18:05:21] <furrywolf> XXCoder: it's certainly the most clever design I've seen. the only moving part is the fluid...
[18:05:45] <XXCoder> yep. while solar one I linked you uses sun to turn panel towards subn
[18:06:04] <XXCoder> so it doesnt even need to be plugged in, but it does use motor that evenually wears
[18:06:45] <Cromaglious_> furrywolf: exactly
[18:06:56] <furrywolf> I decided trackers weren't useful where I currently am... my morning sun is blocked by mountains and the evening sun by trees, so the benefits of tracking would be less.
[18:07:10] <furrywolf> Cromaglious: exactly? complete with the exploded capacitor? :)
[18:07:21] <XXCoder> and the chair too
[18:07:25] <XXCoder> heh
[18:07:57] <Cromaglious_> ok Very similar - the expolded cap
[18:08:11] <XXCoder> furrywolf: it would aim to most light whenever so not too bad actually
[18:08:26] <Cromaglious_> mine got zapped, now exploded caps
[18:08:37] <Cromaglious_> no boomed caps
[18:08:55] <XXCoder> http://www.mdpub.com/suntracker/images/headdim.jpg the sensor and power source lol
[18:09:20] <XXCoder> attached http://www.mdpub.com/suntracker/images/headmounted.jpg
[18:10:22] <XXCoder> field problem fixed hack http://www.mdpub.com/suntracker/images/1stbar.jpg
[18:10:58] <furrywolf> these days panels are so cheap I suspect we'll see a lot fewer trackers in PV systems
[18:11:14] <XXCoder> final version http://www.mdpub.com/suntracker/images/barworking.jpg
[18:11:36] <XXCoder> guess so if can just point in couple peak times
[18:12:12] <tiwake> finally got google sketchup version 8 working
[18:12:20] <XXCoder> tiwake: nice :)
[18:12:34] <Cromaglious_> that's so when there is output from the tracking panels it'll rotate until both panels are receiving identical amounts of light?
[18:12:45] <XXCoder> Cromaglious_: yeah
[18:12:57] <XXCoder> when equal there is no volt difference
[18:13:03] <tiwake> now I need to decide the shape of the house... heh
[18:13:03] <XXCoder> so motor dont rotate
[18:13:25] <Cromaglious_> and when output is < certain voltage it won't track like at night?
[18:13:26] <tiwake> meh, shape would depend on size of the property
[18:14:02] <XXCoder> it depends on difference not amount (well besides not enough difference to rotate in first place)
[18:14:11] <XXCoder> night it gets no power so it wont even move
[18:14:28] <XXCoder> morning one side would be well lit, making good voltage difference so it would start turning
[18:14:30] <Cromaglious_> ahh self powered kewlios
[18:14:56] <Cromaglious_> or is it getting power from the main panels?
[18:15:02] <XXCoder> nope
[18:15:07] <XXCoder> from what I see anyway
[18:15:56] <XXCoder> guy apparently figured how to waterproof it., http://www.mdpub.com/suntracker/images/weatherproof.jpg
[18:17:24] <XXCoder> love how guy updates stuff but dont remove old stuff
[18:17:25] <XXCoder> http://www.mdpub.com/suntracker/images/newsensors2.jpg
[18:17:32] <XXCoder> sensor version 2
[18:18:31] <XXCoder> Cromaglious_: http://www.mdpub.com/suntracker/images/newsensors.jpg amazing eh
[18:20:08] <furrywolf> let's say the tracker really does get the full 40% extra power output. when panels were $20/watt, you could spend lots of money on a tracker and still come out ahead. but at $0.70/watt, just adding 40% more panels is a lot easier...
[18:21:54] <XXCoder> furrywolf: yeah but then he probably spent few dollars
[18:22:02] <XXCoder> http://www.mdpub.com/images/125hexback2.jpg he also made this
[18:22:06] <furrywolf> and gives you a much more reliable system with no moving parts, and a 40% increase in power on overcast days too, not just clear ones.
[18:22:22] <XXCoder> he work out in sticks sometimes so he really needs ways to make power.
[18:26:58] <XXCoder> furrywolf: wonder if its worth it to have solar in washington state
[18:27:04] <XXCoder> summers maybe but rest of year
[18:33:11] <furrywolf> you should be able to find solar data for your area online
[18:33:28] <XXCoder> oh yeah
[18:33:42] <XXCoder> doubt will do solar for now, since dont own home here
[18:33:43] <SpeedEvil> XXCoder: It depends.
[18:33:59] <SpeedEvil> XXCoder: First step - can you feed back to the grid, or do you need to use it promplty
[18:34:28] <SpeedEvil> If you have to use it locally - then that sets the maximum practical solar typically at ~2* baseload or so probably
[18:34:44] <SpeedEvil> Unless you have a lot of sun correlated load.
[18:34:47] <SpeedEvil> AC for example
[18:35:01] <SpeedEvil> then going as large as your AC or even more can be worth it
[18:35:45] <XXCoder> http://www.nrel.gov/gis/images/map_pv_us_annual10km_dec2008.jpg
[18:35:54] <XXCoder> im at bad corner of usa
[18:36:13] <XXCoder> 303.5
[18:36:17] <XXCoder> er 3-3.5
[18:36:59] <XXCoder> http://www.nrel.gov/gis/images/map_csp_us_10km_july_feb2009.jpg 2009
[18:37:02] <XXCoder> july
[18:37:21] <XXCoder> its only NOT red area in washington lol place I live at sucks sun-wise
[18:37:52] <XXCoder> winter http://www.nrel.gov/gis/images/map_csp_us_10km_december_feb2009.jpg below 2 lol
[18:38:43] <SpeedEvil> What would you be wanting this for
[18:38:49] <SpeedEvil> Do you have AC?
[18:38:55] <XXCoder> nah just was mostly curious.
[18:39:07] <XXCoder> but yeah if I ever need it, I would use solars for AC
[18:39:12] <XXCoder> its BIG power use
[18:39:25] <SpeedEvil> I note as a datapoint - that in order to power a 1 watt load 24*7, I need a 250W solar panel and a 100Ah battery here
[18:39:38] <SpeedEvil> And it still may die if there is an unsunny dec/jan
[18:39:48] <SpeedEvil> (Scotland)
[18:39:53] <XXCoder> AC only solar is nice idea
[18:40:01] <XXCoder> covers bad times when its REALLY sunny
[18:40:14] <XXCoder> easy enough to build something like guy did
[18:41:14] <SpeedEvil> Of course, shading, insulation, ... are all reasonable things to approach first
[18:41:27] <XXCoder> yeah

[19:08:00] <Cromaglious_> Sunny and 92F here
[19:08:21] <Cromaglious_> Long sleeve weather
[19:08:39] <XXCoder> heavy rain and winds here
[19:08:43] <XXCoder> typical spring
[19:10:00] <furrywolf> ... 92F is naked in the pool weather, not long-sleeve weather
[19:12:27] <Cromaglious_> for me it's long sleeve weather... Keep the sun off me... and a wide brimmed had
[19:12:30] <Cromaglious_> hat
[19:14:29] <_methods> damn 92 where you at?
[19:14:42] <_methods> that's my kinda weather there
[19:14:57] <XXCoder> 92f comes up pretty often during summer but not any other time. usually only july
[19:15:15] <_methods> it was only about 75 today
[19:15:18] <SpeedEvil> furrywolf: AC is something I think I could really use one or two days a decade
[19:15:20] <XXCoder> too bad usa didn't sign paper on say sept 1776 lol
[19:15:27] <XXCoder> not july 4th :P
[19:15:51] <furrywolf> 92F is way too fucking hot
[19:21:01] <Cromaglious_> Almost warm enough
[19:21:56] <Cromaglious_> Temecula, CA on I15 2miles north of San Diego County 7 miles east of the Eastern side of Orange County
[19:22:16] <Cromaglious_> Riverside county
[19:22:37] <_methods> i'll take the weather but you can keep the state lol
[19:22:56] <Cromaglious_> hehe I'm warmer than Blythe, CA
[19:24:04] <Cromaglious_> Hehe Richmond California and Virginia are both 60F today
[19:25:48] <Cromaglious_> hehe SketchUcam is stuck in a loop.. 5.5MB and still growing
[19:27:28] <Cromaglious_> 10MB still going
[19:28:15] <Cromaglious_> ok sketchup really needs a ^c or Break handler...
[19:28:28] <Cromaglious_> or ESC
[19:29:52] <furrywolf> kill -9?
[19:30:50] <Cromaglious_> I don't have pstools on here yet
[19:31:07] <Cromaglious_> pskill -1 would be nice if the app knew what to do with it

[19:39:40] <furrywolf> http://www.guru3d.com/articles-pages/danamics-lmx-superleggera-review.html am I the only one who thinks NaK is just plain overkill for a cpu cooler?
[19:40:55] <alex4nder> sounds good to me
[19:42:12] * furrywolf waits for the inevitable spill, formation of potassium superoxide, and resulting wrongful death lawsuit...
[19:42:40] <furrywolf> or product safety lawsuit or something else expensive
[19:44:38] <furrywolf> as a general rule, all sealed systems eventually leak. and, as a general rule, NaK is nice and reactive...
[19:45:26] <malcom2073> But furrywolf, they simple don't believe it can leak!
[19:45:34] <malcom2073> "We simply don't believe it can!"
[19:46:06] <furrywolf> right, and fridges, a/c systems, nuclear reactors, oil pipelines, etc don't leak either. :P
[19:47:05] <furrywolf> maybe it won't even happen to the end-user. maybe it'll get disposed of with household waste, be crushed in the back of a garbage truck, in a puddle of garbage-glop with both water and organic compounds, both of which cause explosions...
[19:48:07] <malcom2073> Nah man, it's like the leaded stuff, and batteries. I'm SURE people follow the disposal instructions, don't they?
[19:48:36] <XXCoder> thats crazy
[19:48:56] <furrywolf> the good news is it's so expensive no one will actually buy one.
[19:49:44] <XXCoder> maybe people who thought monster cables meant better found at $200 per cable would buy that
[19:49:59] <furrywolf> lol
[19:50:07] <malcom2073> +1
[19:50:11] <malcom2073> Something to be said for buzzword
[19:50:12] <malcom2073> s
[19:51:12] <furrywolf> ohhhhh, that's a good idea. NaK speaker wires! "Our unique liquid metal conductors allow electrons to flow more freely than outdated copper conductors, give your sound clarity and nuance as you've never heard before! Starting at only $1499.99 for a pair of our premium 3-foot cables."
[19:51:34] <renesis> 00:28 < XXCoder> maybe people who thought monster cables meant better found at $200 per cable would buy that
[19:51:46] <renesis> theyre not bad cables if you can get an artist or distributor discount
[19:51:52] <renesis> they have lifetime warranty
[19:52:04] <XXCoder> NaK cables lol
[19:52:06] <renesis> but yeah @ full price theyre a joke
[19:52:17] <renesis> hosa cable ftw
[19:52:51] <renesis> except for the hosa cable with switchcraft ends, fuck all that dinosaur shit
[19:52:51] <furrywolf> they'd have to be made out of crystal-clear jacketing with some kind of inner texture so you can see the liquid metal squish as you flex the cables...
[19:53:23] <renesis> so normal crap 'audiophile' speaker cable
[19:53:39] <renesis> i do love how the lens effect of the cable makes the tiny conductors look huge
[19:54:07] <renesis> cable leaks would suck
[19:54:30] <furrywolf> I have some old monster cable that is legitimately 10AWG... but I bought it at yard sales, not retail.
[19:54:48] <renesis> the wire is usually fine, they redesign the ends all the time
[19:54:52] <furrywolf> I'm not using it, because it doesn't fit in the terminals on any of my speakers. :P
[19:55:03] <renesis> custom plastic overmolds, weird boots
[19:55:15] <renesis> most of the stuff ive used, the ends dont last more than a year or so
[19:55:23] <furrywolf> my stereos are both wired with a mix of lamp cord and 16/4 flat trailer wire. :P
[19:55:25] <renesis> hosa is about the quality of the cables that i make myself
[19:55:36] <renesis> using same quality parts
[19:56:06] <renesis> their mid grade (pro) uses rean XLR, which is neutriks consumer brand
[19:56:16] <furrywolf> lamp cord makes excellent speaker wire, as it has heavier, tougher insulation, and unlike speaker wire, they get sued if they invent their own gauge system, and sell undersized wire.
[19:56:33] <renesis> and the high grade (edge) use neutrik nc3, so basically cable full of awesome
[19:56:44] <XXCoder> Just use gauge 000 ;)
[19:56:53] <renesis> furrywolf: i dont like how it splits
[19:57:00] <renesis> sometimes the insulation will be thin on one side
[19:57:13] <furrywolf> only total crap... and speaker wire can do that too.
[19:57:21] <renesis> but yeah thats basically what consumer speaker cable is, lamp cable is usually better insulation
[19:57:29] <renesis> not pro speaker wire
[19:59:09] <furrywolf> 16/4 trailer wire is really nice for running stereo. :)
[19:59:11] <renesis> furrywolf: http://www.waytekwire.com/images/items/SERVICECORD2FL.gif
[19:59:21] <renesis> thats the best shit you can get
[19:59:45] <renesis> goes right into neutrik speakon, and itll fit through a Pomona MDP dual banana plug loop
[20:00:30] <renesis> you can get it 12/4 for biamp speakers, use all of the speakon posts
[20:00:33] <furrywolf> lol
[20:00:46] <renesis> whats lol
[20:00:48] <furrywolf> I don't have fancy terminations. I use consumer-grade speakers with binding posts.
[20:01:03] <furrywolf> lol is because that's just SO cord.
[20:01:03] <renesis> pomona banana plugs are not expensive
[20:01:19] <zeeshan> furrywolf: who you talkin to
[20:01:20] <furrywolf> some of them have binding posts, others have spring clips.
[20:01:23] <zeeshan> renesis?
[20:01:23] <renesis> and speakons and XLR are a few dollar each
[20:01:23] <zeeshan> :P
[20:01:38] <renesis> furrywolf: right i would just twist and insert
[20:01:52] * zeeshan unignores renesis
[20:01:56] <renesis> tho most those binding posts are made to accept banana plug
[20:01:58] <furrywolf> I'm not spending $50 on connectors when I most expensive speakers I have cost me $75. (the JBL 4311s)
[20:02:09] <furrywolf> s/I/the
[20:02:13] <renesis> theyre not always .75" spaced now because fuckin europeans
[20:02:43] <renesis> it would be like $10-15 on connections
[20:02:56] <renesis> and maybe $10-15 in cable, you can buy it at home depot or lowes
[20:03:06] <furrywolf> I'm happy with my flat-4 trailer wire. :P
[20:03:13] <XXCoder> make your own connectors
[20:03:15] <renesis> yeah that works
[20:03:19] <renesis> xxcoder: wot
[20:03:34] <zeeshan> whats wrong with speaker wire
[20:03:37] <renesis> http://www.mouser.com/ProductDetail/Pomona-Electronics/1825-2/?qs=BLrwpM7T1TlH45C7i3Or%252bA%3D%3D
[20:03:52] <renesis> why make them when pomona plugs are $2?
[20:04:01] <furrywolf> http://www.waytekwire.com/images/items/PARALLEL4FL.gif that kind
[20:04:02] <XXCoder> yea was mostly kidding :P
[20:04:23] <XXCoder> zeeshan: nothing a wire #000 would solve ;)
[20:04:29] <zeeshan> lol
[20:04:40] <renesis> furrywolf: yeah i dont like how the insulation doesnt always tear away even
[20:04:47] <renesis> same with standard speaker cable, tho
[20:05:33] <zeeshan> http://images.sonicelectronix.com/images/1310339/big/qw12150-1.jpg
[20:05:40] <zeeshan> thats what i used when i did my stereo in the old beater
[20:06:04] <renesis> for that i would prob used twisted teflon
[20:06:11] <furrywolf> I like it because it lets me run a single cable then easily split it to two speakers, it's color-coded so you don't have to try looking for tiny writing or feeling for a rib on one side, it's #16 which is plenty thick for full-range speakers, it has decently tough insulation (meant to survive in the open under a trailer), and it's cheap.
[20:06:38] <renesis> right thats why pro audio likes the type of cable i linked to
[20:06:55] <zeeshan> renesis is a pro audio expert
[20:07:00] <renesis> all the reasons you said, except outer insulation
[20:07:14] <furrywolf> and cheap.
[20:07:14] <zeeshan> he worked in an audio lab
[20:07:26] <renesis> i work in pro audio development, i dont believe in experts
[20:07:31] <furrywolf> cheap is not a property I apply to ANYTHING sold as "pro audio".
[20:07:52] <renesis> furrywolf its power cable sold at lowes and home depot
[20:07:54] <zeeshan> its wire guys.
[20:07:55] <zeeshan> :)
[20:08:12] <renesis> im telling you not to buy pro audio speaker cable
[20:08:19] <renesis> or shit audiophile speaker cable
[20:08:28] <renesis> just go to lowes and get the good shit
[20:08:41] <renesis> sometimes they will have to order it because they will only have 3 conductor
[20:08:47] <furrywolf> SO cable is round and harder to run, and can't be easily split in two without splices.
[20:08:48] <XXCoder> #000 wires, i'm telling you
[20:08:58] <zeeshan> ???
[20:08:59] <renesis> yes furry i know
[20:09:01] <XXCoder> electrons flow so fast you hear sounds before it sends signals :P
[20:09:09] <renesis> xxcoder: yeah you go to airgas for that
[20:09:14] <renesis> welding cables
[20:09:22] <renesis> car audio does this
[20:09:31] <furrywolf> bbl, housework
[20:09:36] <zeeshan> http://www.wihatools.com/images/PressMaster/strip_tools/Jacket_Strip/44217px350.jpg
[20:09:44] <zeeshan> tool for strippin cables like SO ;p
[20:09:45] <renesis> furrywolf: just saying, if you ever need speaker cable, and you dont have you cable anymore, that stuff works well
[20:10:00] <renesis> i just use an xactor
[20:10:35] <renesis> i dont even cut all the way through, go most the way and bend the other way and itll split
[20:11:03] <zeeshan> ^ unprofessional way
[20:11:08] <zeeshan> stressin copper for no reason :[
[20:12:23] <furrywolf> some places will fire you for using a knife to cut it, rather than using wire cutters in from the end of the cable.
[20:12:27] <jdh> I only use directional cables for my speakers
[20:12:35] <furrywolf> too high of chance of nicking the inner conductor insulation.
[20:13:18] <renesis> thats why you dont go through
[20:13:27] <zeeshan> furrywolf: yep most pro places will
[20:13:33] <renesis> and thats a prob with normal strippers, why i use an xacto
[20:13:47] <zeeshan> as you can see after working in the audio industry
[20:13:50] <zeeshan> renesis is still pro
[20:13:51] <zeeshan> :)
[20:14:13] <zeeshan> jdh: what are direction cables?
[20:14:15] <zeeshan> directional
[20:14:59] <renesis> jdh: people make fun of it on balanced cables, but if you have cables with shield connected on one end, it makes sense
[20:15:20] <renesis> on RCA cables built into balanced cables it would make sense
[20:15:38] <renesis> but on the consumer cables i took apart, we laughed because the shield wasnt connected on either side
[20:16:02] <renesis> cables are a huge scam
[20:16:06] <jdh> for a drain, it woudl actually make sense
[20:16:16] <zeeshan> oh its a shileded cable
[20:16:24] <zeeshan> my rca cable had that
[20:16:36] <renesis> right, so RCA cables sold a shielded that halve arrows could be legit
[20:16:51] <renesis> not the ones i got tho
[20:17:36] <renesis> shielded digital stuff, too
[20:18:03] <renesis> i dont see shielded speaker cables, but prob not a bad idea with some switching amps
[20:18:44] <renesis> also wtf @ firing someone in audio for stripping wire with a knife
[20:18:59] <renesis> mfkr if you do that shit with your teeth and it works well and we hit deadlines, im proud
[20:20:24] <jdh> I haven't used my teeth for that in a long time.
[20:21:06] <renesis> i try and just buy teflon for work so itd prob just fuck up your teeth and stretch the insulation
[20:22:06] <renesis> the silicone insulation would be pretty chewy
[20:22:22] <furrywolf> kenwood sold shielded cables with my amps, if I remember right.
[20:22:33] <renesis> little speakers, no?
[20:22:45] <furrywolf> renesis: stripping with a knife has the risk of nicking the inner conductor insulation.
[20:22:49] <furrywolf> no.
[20:22:53] <renesis> i know so i dont go through
[20:22:55] <furrywolf> monoblocks
[20:22:59] <renesis> and if it goes through, i redo it
[20:23:18] <furrywolf> right, you don't. but it's still a risk, and managers don't want to be inspecting everyone's strippings.
[20:23:27] <renesis> if i cut the outer insulation with anything, any method, im checking all the wires for nicks anyway
[20:23:36] <renesis> i pull apart the insulation with my fingers
[20:23:45] <XXCoder> just realized
[20:23:54] <renesis> wtf managers inspecting strippings
[20:24:07] <renesis> if that shit fucks up its my problem, so im inspecting strippings
[20:24:13] <XXCoder> nes guns dont work because of lcd is different from crt right? I wonder if rom could be calbrated to make it work
[20:24:16] <renesis> engineers not trying to do QA
[20:24:42] <renesis> xxcoder: yeah i dont get it really because i would think it would pick up the light
[20:24:54] <renesis> but i guess maybe LCD black is not black enough?
[20:24:58] <XXCoder> renesis: I suspect its color codes thats different
[20:25:19] <XXCoder> since lcds dont display same
[20:25:28] <renesis> you think it actually looks for white and not just light amplitude?
[20:25:34] <zeeshan> sometimes you cant see the nicks
[20:25:35] <zeeshan> lol
[20:25:47] <furrywolf> it has nothing to do with color.
[20:25:49] <furrywolf> just timing.
[20:25:56] <furrywolf> even I know that, and I don't even play games. lol
[20:25:57] <renesis> if you bend the wire youd see the nicks
[20:26:01] <zeeshan> you cant.
[20:26:05] <zeeshan> if its a small nick
[20:26:09] <renesis> furrywolf: so its refresh issue?
[20:26:14] <furrywolf> yes
[20:26:15] <XXCoder> furrywolf: possibke?
[20:26:32] <renesis> haha now im off ignore so he can argue more
[20:26:40] <zeeshan> at eaton
[20:26:45] <zeeshan> all the strippers were calibrated lol
[20:26:52] <zeeshan> same with crimpers
[20:26:56] <renesis> yeah because color awareness seems to complicated
[20:27:04] <renesis> i always assumed it was a photodiode and a lens
[20:27:19] <XXCoder> "You can't. The way the zapper works is that it's actually a photo sensor (I think that's the right name for it)... the zapper doesn't shoot anything. It actually RECEIVES a beam of light transmitted from the TV. When you pull the trigger while playing a game, you notice a flash on the screen where everything but the target area is black. This is the light being beamed from your TV. If the photosensor sees the light coming up the
[20:27:19] <XXCoder> tube of the gun, it's a hit. LCD TVs don't output light like CRT TVs do."
[20:27:21] <zeeshan> renesis: youre off unignore cause you're a source of entertainment
[20:27:32] <renesis> double negative
[20:27:39] <XXCoder> "off unignore" = ignored
[20:27:47] <zeeshan> XXCoder: it was on purpose
[20:27:49] <zeeshan> trollin
[20:27:50] <renesis> i wish that were actually the case
[20:27:53] <XXCoder> :P
[20:28:03] <renesis> yes he wanted to get bant from the other chan
[20:28:19] * zeeshan wanted to see the pro audio advice
[20:28:23] <zeeshan> so far i like what i see
[20:28:49] <zeeshan> has anyone closed the position loop with scales and steppers in linuxcnc?
[20:28:58] * zeeshan hasnt found any good links on google
[20:29:30] <zeeshan> i saw a youtube video on it
[20:29:43] <furrywolf> think about how analog tv works... the console is generating a raster image, and the tv is drawing it, at exactly the same time. if you aim a photosensor at a specific spot on the crt, when it's triggered, you just look at where you were drawing at the time.
[20:30:45] <renesis> okay so you would have to match latencies
[20:30:45] <furrywolf> there's no framebuffers, no delays other than speed-of-light and switching times of a few transistors.
[20:31:46] <renesis> i remember that white spot being there for a long time
[20:31:57] <renesis> prob like .1, .2 seconds, cant be that hard
[20:32:35] <furrywolf> hrmm. I just googled and found pages saying it works on simple light/dark, which isn't how I've always heard it was done.
[20:32:49] <renesis> its a photodiode
[20:32:54] <renesis> and a lens
[20:33:27] <renesis> it just looks for the white on black square, you could score hits by firing into the right kind of light
[20:33:37] <XXCoder> renesis: I really do wonder if it just needs is value adjustment
[20:33:45] <XXCoder> target #1, 2, so on
[20:33:49] <XXCoder> all has unique colors
[20:33:50] <furrywolf> ah, apparantly the SNES one works like I'm describing, using scanline timing, while the original NES one just used light/dark.
[20:34:03] <furrywolf> no, it has nothing to do with colors. they're all timing based.
[20:34:13] <renesis> SNES on used an IR sensor or something
[20:34:18] <renesis> the bazooka?
[20:34:23] <XXCoder> furrywolf: hmm ok
[20:34:26] <renesis> heh, superscope
[20:34:46] <XXCoder> https://en.wikipedia.org/wiki/NES_Zapper#/media/File:Zapperscope.jpg
[20:34:49] <zeeshan> pcw_home: i found this link: http://linuxcnc.org/index.php/english/forum/38-general-linuxcnc-questions/3916-closed-loop-with-steppers
[20:34:55] <XXCoder> didnt know there was that accessory
[20:35:06] <zeeshan> you say "2. Dont expect good results trying to compensate for backlash with encoder feedback." -- why??
[20:35:18] <renesis> orange gun is weird
[20:35:20] <furrywolf> apparantly the original NES would black the screen, then draw one target white on the next frame, the next target white on the second frame, etc, and time how many frames it took before the gun saw white (if it ever did).
[20:35:22] <renesis> i had the gray gun
[20:35:48] <furrywolf> while the SNES and other systems work like I said, using the beam timing, not needing any special frames or anything else.
[20:35:57] <renesis> yeah white squares happened every time you pulled the trigger
[20:36:15] <XXCoder> ohhh
[20:36:21] <renesis> yeah but they need external sensors
[20:36:24] <XXCoder> wonder if amoled would work
[20:36:31] <XXCoder> because when black, it dont emit light
[20:36:33] <furrywolf> this means the NES guns should work just fine on LCDs, while the SNES and other systems will not.
[20:36:38] <XXCoder> but size is tiny
[20:37:11] <XXCoder> 14 year old article http://www.straightdope.com/columns/read/2304/in-nintendos-duck-hunt-how-does-the-tv-know-when-youve-hit-a-duck
[20:37:18] <furrywolf> it can't have anything to do with black levels, as that's already designed for by compensating for ambient light.
[20:38:01] <furrywolf> it could be that all LCD tvs still have too much lag between when the console sends a frame and when the panel is actually updated for it to correctly time it - it's still working on timing after all.
[20:38:21] <renesis> Since the Super Scope depends on the short persistence and scan pattern of CRT pixels, it will not function with modern displays (such as plasma screens or LCDs) that continuously light each pixel
[20:38:51] <XXCoder> renesis: supercope may theorically work with amoled
[20:39:20] <furrywolf> no design based on scan timing will work on any device with a framebuffer, period.
[20:39:42] <furrywolf> the only one with any chance of working would be the original NES gun, and only if the tv design updated the panel really quickly.
[20:39:54] <zeeshan> http://www.aliexpress.com/store/product/SINO-Linear-Optical-Scale-KA300-Free-Shipping/817985_921420859.html
[20:39:58] <zeeshan> if i wonder if these are any good
[20:40:25] <renesis> xxcoder: i dont think i would burnmuch time trying
[20:40:31] <renesis> superscope was awesome tho
[20:40:35] <XXCoder> LOL https://www.youtube.com/watch?v=rKX9WXRKYGo

[20:43:18] <XXCoder> I noptice driver has own pack. good.
[20:44:10] <XXCoder> groan wish can watch more
[20:44:12] <XXCoder> handhelds
[20:45:27] <XXCoder> "First, it requires extremely precise timing between the trigger pull on the Zapper and the response on the screen."
[20:45:34] <XXCoder> furrywolf: yup youre right
[20:46:17] <furrywolf> this is how you design things with simple hardware. :)
[20:46:41] <furrywolf> sure, there's more robust designs... but they were impossible or impractical at the time.
[20:46:50] <XXCoder> wonder if rom can be hacked
[20:47:03] <XXCoder> so timing can be adjusted
[20:47:35] <furrywolf> probably, but it'd either need to be tuned per-tv, or would need to flash for a much longer period of time.
[20:48:08] <XXCoder> combation of slightly longer flash and adjustable timing
[20:48:12] <furrywolf> and would still only work for original NES guns, not any other system, as they used scan timing, which simply doesn't exist on anything with a framebuffer.
[20:48:49] <furrywolf> you could add a game start calibration screen, where you pulled the trigger to start the game, while it was displaying a test pattern that would time the tv.
[20:49:03] <XXCoder> thats pretty good
[20:49:34] <furrywolf> or you could emulate your games on some modern system with an lcd-compatible gun. :)
[20:49:43] <XXCoder> yeah
[20:50:04] <XXCoder> lol http://www.instructables.com/id/NES-ZAPPER!!!/
[20:50:58] <furrywolf> note how few parts are inside it.
[20:51:06] <XXCoder> yeah
[20:51:55] <furrywolf> it's not recognizing colors or any of the other theories people have come up with. :)
[20:52:15] <XXCoder> I remember reading about colors but may be for other device
[20:52:41] <furrywolf> that laser emitter is way too small. you need to be able to at least pop balloons or something.
[20:53:08] <XXCoder> in one silly comic one lady had her nes zapper converted so it would actually zap stuff
[20:53:22] <XXCoder> and has classic mode where it are to be used as normal zapper
[20:53:35] <XXCoder> she zapped tv by mistake :P
[20:58:20] <XXCoder> http://www.instructables.com/id/Concrete-Lightbulb-Wall-Hook/
[20:58:22] <XXCoder> interesting
[20:59:07] <zeeshan> lol im going through my machining notes for tomorrow's test
[20:59:12] <zeeshan> "variants of turning process"
[20:59:18] <zeeshan> facing parting threading.. and boring
[20:59:22] <zeeshan> boring has a sad face next to it
[20:59:25] <zeeshan> :-)
[20:59:32] <XXCoder> :(
[20:59:39] <zeeshan> poor thing always gets put down
[20:59:46] <zeeshan> yet its the most interesting operation
[20:59:54] <zeeshan> cause you dont know if your tools going to crash! :D
[21:00:38] <zeeshan> heres a quiz q
[21:00:55] <zeeshan> "what is the reason for reamers having an even number of teeth"
[21:01:31] <XXCoder> because odd may be prime and prime isnt good ;)
[21:01:35] <zeeshan> hehe
[21:01:38] <XXCoder> (2 is only even prime)
[21:01:41] <zeeshan> its actually a non technical reason
[21:01:50] <zeeshan> so you can measure the diameter of the reamer
[21:01:57] <XXCoder> makes sense
[21:01:57] <zeeshan> since it's used for precise holes.
[21:01:58] <zeeshan> haha
[21:02:30] <zeeshan> this course i was getting
[21:02:46] <zeeshan> and enjoying , till he started doing all the heat transfer partial differential equations
[21:02:52] <zeeshan> when we got to the thermal section of metal cutting
[21:03:00] <zeeshan> that stuff is intense
[21:03:11] <furrywolf> that seems like a poor process. a standard split mold would result in much faster production, not be full of voids, and wouldn't require carefully scraping off sharp glass, just a bit of flash removal.
[21:03:26] <furrywolf> you could make one mold with a dozen bulbs...
[21:03:51] <furrywolf> hell, the bulb shape is probably tapered enough you could just use a one-piece silicone mold and not even need to clean up the final product.
[21:03:52] <XXCoder> it keeps orginial metal socket at bottom
[21:04:03] <furrywolf> you can mold it into the metal socket. :P
[21:04:36] <XXCoder> Guess so lol
[21:05:10] <furrywolf> also, as a functional issue, the bulb shape is rounded enough it probably doesn't make a good hook, especially being mirror finish.
[21:06:53] <furrywolf> but, you know, art people. :P
[21:07:05] <XXCoder> Right on that article, "one question, how do i make it?"
[21:07:06] <XXCoder> uhhh
[21:07:13] <furrywolf> lol
[21:07:34] <furrywolf> my guess is they didn't realize it was multiple pages.
[21:07:49] <XXCoder> yeah. aloew menioned same thing as you did lol
[21:07:53] <XXCoder> multipart mold
[21:08:05] <furrywolf> because, presumably to show lots of ads I don't see due to having adblockplus installed, many websites like breaking things up into a bunch of small pages.
[21:08:30] <XXCoder> there is mod that combines into one page

[21:09:21] <XXCoder> what ya think http://www.instructables.com/id/How-to-Build-a-Polished-Concrete-Desk/
[21:09:43] <furrywolf> I think concrete sucks.
[21:10:41] <XXCoder> wtf guy added fiber cables into concerete
[21:10:52] <XXCoder> and glasses stuff like beads?
[21:11:32] <furrywolf> make it decorative
[21:12:04] <XXCoder> surface looks good. http://cdn.instructables.com/FQO/RN0H/FZG43SXN/FQORN0HFZG43SXN.MEDIUM.jpg
[21:17:09] <Cromaglious_> DAMN IT! Gumby! sketchUcam BLOZ!!!
[21:17:24] <XXCoder> reached on gb eh
[21:17:57] <Cromaglious_> you have to lie to it to get it to cut stuff small
[21:19:58] <XXCoder> furrywolf: you dont like concerete but do you like epoxy granite?
[21:20:42] <Cromaglious_> fiber reinforce corncrete rocks
[21:20:48] <t12> https://www.dropbox.com/sc/261gp0qrhnejlmm/AAAuAXbARHZOVRW6lWZwL4Xra
[21:20:50] <t12> success
[21:21:14] <Cromaglious_> though a layer of epoxy bonded granite looks better
[21:25:21] <furrywolf> bbl
[21:25:58] <XXCoder> time to convert some organics to human fuel. later
[21:49:13] <Cromaglious_> well I couldn't cut a gear so I cut a radiation signett inside
[22:34:31] <zeeshan> t12 what is that contraption!
[22:35:11] <Tom_itx> this damn board won't run in compatibility mode!
[22:36:49] <Cromaglious_> Just cut a better radiation signett
[22:36:59] <Cromaglious_> copper cuts nice
[22:38:44] <Cromaglious_> ok I just need to get smaller bits to cut smaller gears
[22:42:21] <Cromaglious_> sketchUcam still sucks with a 0.008 cutter even
[23:02:03] <XXCoder> bbbback
[23:04:13] <Cromaglious> ugh,,, sketchUcam It's almost better if I run metric and size scale up 100x then scale in Mach3 by 0.01
[23:07:14] <XXCoder> wow
[23:10:30] <Cromaglious> sketchucam doesn't like operating in 0.0001" range... probably better if I go to inch 1000x and scale by 0.0001 in mach3
[23:10:44] <Cromaglious> 0.001
[23:11:20] <XXCoder> wonder why
[23:12:09] <Cromaglious> probably using single pression internally
[23:12:50] <Cromaglious> so instead of 7 inches I tell it 7000inches
[23:13:18] <XXCoder> 7000 in now thats tiny lol
[23:13:42] <XXCoder> yo
[23:13:44] <Cromaglious> 45 tooth gear, 2" across
[23:14:14] <Cromaglious> using 1/16 microstep to get the steps
[23:14:36] <Cromaglious> 20320 per inch
[23:18:18] <XXCoder> pretty fine
[23:19:17] <furrywolf> microstepping doesn't translate directly into resolution... I have some drivers that'll do 256 microsteps, and I'm willing to bet there's absolutely no movement of the table between most of them...
[23:19:41] <zeeshan> yhep
[23:19:45] <zeeshan> and i checked this on my lathe too
[23:19:48] <zeeshan> microstepping is bs
[23:20:11] <Cromaglious> backlash counts too
[23:20:12] <zeeshan> im on 1/4 microstep and that works out to like .0001 resolution
[23:20:15] <zeeshan> it doesnt move
[23:20:26] <zeeshan> with 0 backlash (on my x-axis)
[23:20:35] <zeeshan> and if youre moving in the same direction, there is no backlash
[23:20:37] <zeeshan> and it doesnt mean
[23:20:45] <zeeshan> smallest itll move is 0.0005"
[23:21:03] <XXCoder> .0005 is pretty decent and work for most jobs
[23:21:51] <furrywolf> that said, when I turn up my microstepping, it runs much quieter and smoother...
[23:21:59] <Cromaglious> I see the stepper move, but if there is backlash it doesn't move and if it's going in the same direction I may see carriage movement
[23:22:02] <zeeshan> but you lose holding torque
[23:22:08] <zeeshan> i think 1/4 microstep is pretty good
[23:22:24] <zeeshan> you're at 77.77% holding torque i believe
[23:22:33] <furrywolf> I decided on 10 microsteps. it limits my top speed slightly, but 5 is a lot noisier.
[23:22:42] <furrywolf> right, and I have absolutely no shortage of holding torque.
[23:23:19] <furrywolf> I might actually reduce the motor current, as right now Z rips the bushings out if you run it all the way up...
[23:23:23] <Cromaglious> problem with sketchucam is if it's too small it will not see it and ignore it.
[23:23:34] <furrywolf> and they're a pain in the neck to readjust.
[23:23:36] <zeeshan> what kind of silly cam program is
[23:23:36] <zeeshan> haha
[23:23:41] <zeeshan> *is this
[23:25:31] <furrywolf> holding torque doesn't tend to be the limit... fast movement is the problem.
[23:26:05] <furrywolf> you don't actually need ANY holding torque on a mill with acme leadscrews. heh.
[23:26:19] <zeeshan> yea well i dont have that :p
[23:27:41] <furrywolf> I have enough low-end torque to damage my mill, so I'm not worried about microstepping losing some of it. heh.
[23:27:57] <zeeshan> what size steppers
[23:28:15] <furrywolf> I'd like more top speed, but too much work. I'd need to re-gear (it has a 2:1 belt reduction stock) or do expensive upgrades.
[23:28:20] <furrywolf> nema34, 944ozin.
[23:28:24] <zeeshan> pretty big :)
[23:28:33] <furrywolf> or maybe it was 960. I don't remember which spec sheet goes with what anymore
[23:28:40] <zeeshan> im gettin about 100 ipm out of the 1200 oz-in
[23:28:48] <zeeshan> i thought it was bad, but apparently thats where its supposed to be
[23:29:30] <XXCoder> 110 n.cm
[23:29:32] <furrywolf> I get 1.8in/s at reasonable acceleration, higher if I set the acceleration slow. linuxcnc needs some acceleration that depends on current velocity, rather than fixed.
[23:29:51] <furrywolf> I think I have the limit set at 1.2in/s now, due to hitting my step limit.
[23:30:28] <XXCoder> ah 155.773 oz/in
[23:30:40] <furrywolf> the stand the mill is on resonates badly around 1.5in/sec. I'd need to remove the handwheels or build perfectly balanced ones.
[23:30:40] <XXCoder> heh mines weak compared to your beasts
[23:30:54] <zeeshan> XXCoder: but i bet yours can move at 600 ipm
[23:30:56] <XXCoder> make base more beefy?
[23:30:57] <zeeshan> on the same setup :)
[23:31:05] <furrywolf> my motors weigh about ten pounds each, and are running at 8.5A/phase off a 56V supply.
[23:31:10] <Cromaglious> I can do .33"/s
[23:31:45] <zeeshan> furrywolf: think if i up the current
[23:31:48] <furrywolf> I might re-transformer the supply for 65ish volts.
[23:31:48] <zeeshan> i can get more speed out of it?
[23:31:50] <furrywolf> no
[23:32:09] <furrywolf> to get more speed, you up the voltage, not the current. it only ever sees the current limit at stop or near stop.
[23:32:23] <Cromaglious> then again I'm running a yoocnc piece of crap
[23:32:24] <zeeshan> i forget the torque formula
[23:32:27] <furrywolf> once you're moving, it never gets near the current limit.
[23:32:29] <zeeshan> that relates to vi
[23:32:57] <zeeshan> well im already maxed out then :p
[23:33:02] <zeeshan> the drives i think handle 80vdc
[23:33:05] <zeeshan> and im running a 65vdc supply
[23:33:09] <zeeshan> kinda near the limits
[23:33:15] <furrywolf> doubling voltage doubles torque at a given speed, or gives you more speed (how much more your motors have a little graph to show) at the same torque.
[23:33:40] <furrywolf> yeah, mine are rated for 80V too. I went with 56V because I found a transformer cheap, but I might go up to 65V.
[23:33:58] <furrywolf> my caps are 75V, so I need to stay below that with some margin for braking.
[23:34:09] <Cromaglious> well going from a tb6560 to a tb6600 I can go from 24v to 45v
[23:34:37] <furrywolf> Cromaglious: be warned many of those chinese boards fry above 24V, regardless of ratings. google the board first.
[23:34:55] <Cromaglious> they're suggesting 36v for the tb6600
[23:36:02] <furrywolf> don't google the toshiba chip. google the board.
[23:36:32] <XXCoder> chip may be fine but other stuff may not be
[23:36:54] <furrywolf> I've seen several mentions of those boards catastrophically failing even when they're rated for higher voltages.
[23:37:13] <Cromaglious> http://itslinux.org/cnc/0313.html
[23:38:12] <Cromaglious> last 2 pics.. tb6600 is the black heat sink
[23:38:18] <XXCoder> http://itslinux.org/cnc/touchSensor.jpg
[23:38:24] <XXCoder> cnc sensor?
[23:38:27] <zeeshan> theres gotta be a formula for maximum stepper speed
[23:38:28] <XXCoder> to find x,y so on?
[23:38:35] <zeeshan> based on voltage and inductance
[23:38:41] <zeeshan> and maybe resistance
[23:39:08] <furrywolf> zeeshan: no. there's a graph in the datasheet for the motor.
[23:39:17] <zeeshan> i dont believe you
[23:39:52] <furrywolf> Cromaglious: again, the CHIP is rated for higher voltage, and the board may be RATED for a higher voltage, but that doesn't mean it actually WORKS at a higher voltage, because the boards are CRAP.
[23:40:05] <Cromaglious> it's a induction youch probe, still figuring them out
[23:40:31] <furrywolf> showing me a picture of the heat sink won't change this. :P
[23:40:39] <toastydeath> induction probes are pretty simple devices
[23:40:43] <zeeshan> rev/s = [V/(L*2*I_max)] / (steps/rev)
[23:40:56] <zeeshan> so for my motor that works out to 4.17rev/s
[23:41:04] <Cromaglious> yeah, think I'm gonna have to get a ardunio to read them
[23:41:06] <toastydeath> http://www.efunda.com/designstandards/sensors/lvdt/images/lvdt_how.gif
[23:41:16] <zeeshan> 250 rpm
[23:41:25] <toastydeath> you can read them with an oscilloscope
[23:41:30] <toastydeath> as long as you have a driver signal
[23:41:47] <toastydeath> (100khz sine wave from a signal generator works)
[23:42:04] <XXCoder> I wonder if my board supports contact zero finding
[23:42:11] <XXCoder> like this http://cdn.instructables.com/FF6/KZD9/HL946T8F/FF6KZD9HL946T8F.LARGE.jpg
[23:42:32] <Cromaglious> well I want a touch sensor for the cnc, so I'll probably get a nano to read it and output a go/no go signal
[23:42:32] <zeeshan> haha
[23:43:52] <furrywolf> that's just a generic input, the board doesn't need to do anything special. (and that one isn't even an input - it just lights the LED!)
[23:43:57] <Cromaglious> it works, whatch laughing at?
[23:44:37] <XXCoder> Cromaglious: you can abuse touch sensor for this http://hackaday.com/2014/07/31/milling-curved-objects-with-a-g-code-ripper/
[23:44:42] <zeeshan> clearly this number is way off
[23:44:48] <zeeshan> 250 rpm * .196 in /rev
[23:44:58] <zeeshan> apparently im limited to a max of 49 ipm
[23:45:01] <zeeshan> im breaking physics
[23:45:15] <XXCoder> blinding fast lol
[23:45:20] <XXCoder> ya sure using right units?
[23:45:23] <zeeshan> i thinkso
[23:45:23] <furrywolf> what part of "no. there's a graph in the datasheet for the motor." is difficult?
[23:45:27] <zeeshan> 5mm pitch
[23:45:33] <zeeshan> which is .196 in / rev
[23:45:45] <zeeshan> furrywolf: there is actual graph
[23:45:47] <zeeshan> and theoretical
[23:45:57] <zeeshan> when there is no graph, you need to rely on theoretical to get you close
[23:46:04] <furrywolf> there's various rules of thumb and guesstimates, and they're not replacements for test results.
[23:46:08] <zeeshan> in this case its off by 50 ipm :)
[23:46:17] <zeeshan> obviously
[23:46:23] <zeeshan> but you need test results to begin with
[23:46:27] <furrywolf> what brand/model are your motors?
[23:46:33] <zeeshan> automation technologies 1200 oz-in
[23:46:47] <Cromaglious> XXCoder, that is seriously kewlness!
[23:47:05] <furrywolf> that's a torque rating, not a model. a model is generally a long ugly alphanumeric sequence.
[23:47:07] <XXCoder> yeah. I want to design something
[23:47:34] <XXCoder> did you see bat video?
[23:47:42] <zeeshan> KL34H2120-60-4B
[23:49:22] <Cromaglious> not yet
[23:49:38] <XXCoder> it dont seem to use probe so dunno why its there but cool
[23:49:56] <furrywolf> hrmm, look like rebranded chinese something, might need to figure out actual manufacturer...
[23:50:00] <Cromaglious> yeah, the engraving looked flat on the bottom of the bat
[23:50:14] <furrywolf> next time get motors from a brand. :)
[23:50:21] <zeeshan> http://www.kelinginc.net/KL34H2120-60-4AT.pdf
[23:50:23] <zeeshan> this might be it.
[23:52:13] <furrywolf> it's probably similar, yes.
[23:52:24] <furrywolf> note that's series wound, you've hopefully wired yours for parallel.
[23:52:26] <zeeshan> so i guess 6000 / 200
[23:52:31] <zeeshan> yea mine are paralle
[23:52:37] <furrywolf> which does change the curve slightly...
[23:53:02] <furrywolf> (well, it changes it substantially - two times I think - but it also tweaks the shape slightly)
[23:53:40] <zeeshan> a little bit less speed with bipolar parallel
[23:53:43] <zeeshan> but much more torque
[23:54:10] <furrywolf> but your limiting speed is where you run out of torque, so... :P
[23:54:46] <furrywolf> it may have a lower nothing-attached-to-the-shaft speed, but it will probably have a higher top speed with a load.
[23:55:23] <furrywolf> find a graph for another motor that shows both, and note how the parallel curve is above the series curve almost until it hits 0 torque.
[23:55:49] <zeeshan> 6000 pulse/s * 1/200 rev/pulse * 60 s/min
[23:56:04] <zeeshan> 1800 RPM
[23:56:25] <zeeshan> *.196 in/rev = 352.8 ipm
[23:56:31] <zeeshan> so im at 1/3 that almost.
[23:56:58] <furrywolf> first, your graph is at 100V, while you're not running 100V, so you have a factor there.
[23:57:05] <zeeshan> thats true
[23:57:44] <zeeshan> assuming linear relationship (doubt it)
[23:58:04] <zeeshan> 0.35 * 352.8ipm =123 ipm
[23:58:04] <zeeshan> wow
[23:58:07] <zeeshan> thats pretty AWESOME
[23:58:12] <furrywolf> also, you can't do that without knowing how much torque you need. both to overcome friction on the machine, and to accelerate the weight of the screws, table, vise, part, etc.
[23:58:18] <zeeshan> cause i can hit 120 ipm , but ive got it down to 100 ipm for a buffer
[23:58:28] <zeeshan> i cant believe voltage makes that much of a diff.
[23:58:38] <furrywolf> if you set your acceleration down reallllly slow, you can get the speed up a lot higher...
[23:58:43] <zeeshan> ive tried
[23:58:45] <zeeshan> it doesnt effect it really
[23:58:55] <zeeshan> its set to 10in/s^2
[23:58:58] <furrywolf> voltage is roughly linear. 65v is about .65 the torque of 100v.
[23:59:15] <zeeshan> whoops not .35
[23:59:15] <zeeshan> duh
[23:59:26] <zeeshan> okay thats 229 ipm then
[23:59:35] <zeeshan> so it drops by over 100 ipm
[23:59:50] <zeeshan> need 100vac drives!
[23:59:57] <furrywolf> also, those are half-step pulses, so you need 1/400 rev/pulse.
