[02:01:14] <DJ9DJ> hi Jymmm :D
[02:01:19] <Jymmm> hi
[02:29:22] <Loetmichel> mornin'
[06:32:31] <Loetmichel> *cleaning my mini CNC mill* ... WHAT a MESS! -> http://www.cyrom.org/palbum/main.php?g2_itemId=14034
[06:33:25] <Loetmichel> ... and now i know why the x axis has somtimes probnlems with ref move... *searching fpr a identicval microswitch* ... -> http://www.cyrom.org/palbum/main.php?g2_itemId=14037
[07:10:17] <jthornton> isn't that a normal microswitch?
[07:20:01] <archivist> normal switches are broken?
[07:24:01] <jthornton> for me they are
[07:38:54] <Loetmichel> jthornton: it is
[07:39:34] <Loetmichel> but i have only one size smaller in numbers. had to search a while for a normal sized one :-)
[07:46:20] <ReadError> in yalls controller boxes, do you use 120/220v fans?
[07:46:24] <ReadError> or a DC inverter ?
[07:48:39] <cpresser> ReadError: i use 220V fans
[08:02:37] <ReadError> yea i need to get 4
[08:02:47] <ReadError> ill have 2 boxes, so 1 intake, exhaust on each
[08:12:06] <r00t4rd3d> 12v
[09:52:47] <fragalot> SUCCESS
[09:53:06] <fragalot> I managed to fix my mill's bow issue on milled surfaces
[09:53:57] <fragalot> turns out it was because the X rods being held in place with bolts & a lock washer
[09:54:03] <fragalot> removed the lock washer, problem solved.
[09:55:50] <fragalot> table is still bowed though, and now it also appears to have issues with missing steps, but i'm blaming the super shitty chinese driver for that
[09:56:09] <r00t4rd3d> tb6560?
[09:57:18] <archivist> if your shafts are not parallel it will be stiff and need more force causing missed steps
[09:58:13] <fragalot> archivist: it's more due to heat issues
[09:58:34] <fragalot> I can move the carriage by blowing on it, so that's certainly notit
[09:58:47] <archivist> if it was not happening before...why blame heat
[09:59:01] <Tecan> http://www.richsoil.com/rocket-stove-mass-heater.jsp
[09:59:15] <fragalot> archivist: because i've never ran it this long because it never worked right
[09:59:31] <fragalot> this long being over 10 minutes continuously
[09:59:58] <fragalot> r00t4rd3d: dno, came in an unmarked aluminium box
[10:00:03] <archivist> add fan/heatsink to stepper drivers
[10:00:07] <fragalot> archivist: the missing steps also happen in random locations
[10:00:11] <fragalot> archivist: Aye
[10:00:43] <archivist> also reduce top speed and acceleration rate a bit
[10:01:28] <fragalot> did that
[10:01:56] <fragalot> waiting for it to cool down & see if i could turn down the current a little to help with heat
[10:02:18] <archivist> any alignment issues stepper to screw
[10:02:35] <archivist> or screw stiffness
[10:02:53] <fragalot> the screw is supported on both ends, later today I had planned to take the support bearing out
[10:15:58] <r00t4rd3d> you have a pic of your controller?
[10:16:20] <r00t4rd3d> how can you set it up right if you dont know what it is?
[10:16:53] <fragalot> r00t4rd3d: *shrug* it came with the machine & mostly worked
[10:17:05] <ReadError> r00t4rd3d
[10:17:06] <ReadError> http://www.reddit.com/r/pimpcats
[10:23:18] <fragalot> r00t4rd3d: LN298N's - I should be able to heatsink them nicely..
[10:23:52] <fragalot> or I could just use my own controller instead.. bit bulkier compared to this one, but much more potent
[10:25:25] <mrsun> or buy a better controler :P
[10:29:00] <fragalot> mrsun: yea :P
[10:29:18] <mrsun> those only go half step dont they ?
[10:29:30] <mrsun> or the LN298 isnt that jus the h-bridge ?
[10:29:42] <fragalot> that's just the H bridge
[10:29:54] <archivist> needs the 297 too
[10:29:56] <mrsun> paired with 297
[10:30:00] <mrsun> it does half step right ?
[10:30:58] <archivist> yes
[10:31:35] <archivist> just happened to be cataloguing the SGS databook today so on the pile on the desk
[10:31:41] <fragalot> I do have a pololu board laying about but using that one for my printer and I don't really want to cannibalize it :P
[10:31:56] <mrsun> but isnt the L298 "stackable" so you can make them handle more current? :)
[10:32:02] <mrsun> alas, less heat :P
[10:32:36] <fragalot> mrsun: *or* I could just lob on a small heatsink
[10:32:40] <fragalot> (atm they have none in the chinese controler)
[10:32:44] <mrsun> :P
[10:32:52] <mrsun> could do some good :P

[10:38:02] <Jymmm> Tecan: 7000 LBS ?!?!?!
[10:38:21] <fragalot> Jymmm: it's supposed to be heavy
[10:38:22] <fragalot> :P
[10:38:30] <fragalot> that's the whole idea behind the term "mass"
[10:38:41] <r00t4rd3d> I am about to tear down this brand new engine and match/port/polish all the things http://i.imgur.com/2Phhw6h.jpg
[10:38:44] <fragalot> That said, I love the simplicity, yet efficiency of a rocket stove
[10:38:54] <Jymmm> fragalot: My SUV is "mass", but still dont weight THAT much
[10:38:55] <fragalot> r00t4rd3d: enjoy!: :)
[10:38:59] <r00t4rd3d> clean the fins up also
[10:39:04] <fragalot> Jymmm: your SUV isn't made out of solid cob
[10:39:15] <Jymmm> fragalot: Not sure about that
[10:39:24] <fragalot> lol
[10:40:06] <fragalot> Jymmm: that said it's only as heavy as you want it
[10:40:20] <fragalot> the reason for the mass is so that it keeps giving off heat for a long period of time after it's run out of wood
[10:40:27] <fragalot> if you want instant response, don't use any cob
[10:40:37] <Jymmm> Tecan: http://www.ernieanderica.info/rocketmassheaterpermitting
[10:40:41] <fragalot> instant efficient heat, but once you run out of wood, it immediately stops heating
[10:41:07] <Tecan> no
[10:41:11] <Jymmm> fragalot: No
[10:41:30] <Jymmm> fragalot: 12+ hours later it's still radiating heat
[10:41:42] <fragalot> Jymmm: IF you use the cob to add mass, yes
[10:41:57] <fragalot> if you don't, and only use the pipes, then no.
[10:42:22] <Jymmm> fragalot: Go steal a controller already!
[10:42:32] <fragalot> xD
[10:43:38] <Jymmm> Tecan: Wood stove pellets
[10:44:40] <Tecan> yes that would work good too but it might be too dense to let air through you'd have to use a air compressor :)
[10:45:02] <Jymmm> slow fed the pellets
[10:45:29] <Tom_itx> pellet stoves aren't that cost effective are they?
[10:45:37] <Tom_itx> unless you're getting pellets for nothing
[10:45:40] <Jymmm> or a narrow pellet feed and 3x larger air feed with dampener
[10:45:58] <Tom_itx> $3-5 a bag costs more than natural gas doesn't it?
[10:46:14] <Jymmm> Tom_itx: they burn very sowly
[10:46:26] <Tom_itx> half bag a day?
[10:46:27] <Jymmm> almost 100% effeciant
[10:46:43] <Tom_itx> boils down to the bottom cost line
[10:47:10] <fragalot> I quite like gas for several very simple reasons
[10:47:14] <fragalot> a) no storage
[10:47:15] <Jymmm> Well, the biggest pellet producre I know of is in AZ
[10:47:16] <fragalot> b) no mess
[10:47:22] <Tecan> thats the whole idea of the rocket stove it burns more of the wood
[10:47:25] <fragalot> c) it's just there when you want it
[10:47:35] <fragalot> Tecan: it also burns the wood gas
[10:47:38] <fragalot> which is the important bit
[10:47:57] <Jymmm> fragalot: he knows that, now go steal a controller
[10:48:05] <fragalot> I have
[10:48:13] <Jymmm> fragalot: get caught this time
[10:48:18] <fragalot> :<
[10:49:15] <Jymmm> Tecan: I bet you you extended the intake/exhaust, and have them both on the same side, might get better effeciancy
[10:50:15] <archivist> as heat rises how are you supposed to light it and start it running, I see no exhaust fan
[10:50:16] <fragalot> why would the intake need to be extended?
[10:50:47] <Jymmm> fragalot: Just turn yourself into the police already
[10:50:49] <fragalot> archivist: you shove some paper down deep to get the flow going & build up your fire
[10:51:14] <Tecan> theres videos on the link i posted
[10:51:19] <Jymmm> archivist: convection
[10:51:21] <Tecan> lots of them
[10:51:34] <L84Supper> isn't the final exhaust temp supposed to be as close to the input temp as possible for maximum efficiency?
[10:51:35] <fragalot> Jymmm: I've built several rocket stoves - the intake length isn't as important as the exhaust one
[10:51:54] <Jymmm> fragalot: Go rob a bank
[10:51:56] <Tecan> fragalot have pics ?
[10:51:57] <fragalot> L84Supper: Yes.
[10:52:25] <fragalot> Tecan: not really, most of it was made out of scraps & rebuilt several times before I decided that gas was so much easier than hauling wood around, and a lot less messy :P
[10:52:59] <fragalot> I really should document the things i do a bit more :/
[10:53:26] <Tecan> where did you first readabout it ?
[10:53:47] <fragalot> stumbled on it when I was researching woodgas stoves
[10:54:57] <Tecan> ever seen a stirling engine made out of 2 45 gal drums ?
[10:55:24] <fragalot> Tecan: where the hell did you find that?
[10:55:25] <fragalot> :D
[10:55:57] <Tecan> never seen one always wanted to make one
[10:56:03] <Jymmm> fragalot: He saw it at a bank he robbed, you should too
[10:56:29] <fragalot> I started working on making a flame licker engine, then my friends' lathe broke and I've never really continued since then
[10:56:30] <L84Supper> http://phys.org/news/2013-02-fujifilm-thermoelectric-material.html they don't have a real spec (so it's BS)
[10:56:31] <fragalot> :/
[10:57:06] <fragalot> Jymmm: i've had plenty of opportunity to do so in the past, but i'm so rich that I don't see why I would bother
[10:57:24] <L84Supper> are there any natural gas powered stirling engines for sale?
[10:57:36] <Jymmm> fragalot: So you're a cheap bastard and bought a crappy controller instead?
[10:57:58] <fragalot> L84Supper: stirling engine is powered by any gas really - it's based on thermal expansion, not combustion
[10:58:12] <fragalot> Jymmm: I wasn't rich back then
[10:58:17] <Jymmm> lol
[10:58:20] <L84Supper> yes, I know, I'd just like to buy one ~5KW
[10:58:35] <fragalot> L84Supper: the specs they give are for a 234151 m² sheet
[10:58:41] <fragalot> L84Supper: 5kW stirling engine eh
[10:58:42] <fragalot> good luck
[10:58:43] <fragalot> :P
[10:59:50] <L84Supper> they are always a few months away
[11:01:09] <fragalot> L84Supper: quote from their source site: "The exhibited thermoelectric converter module has a power generation capacity of several milliwatts and is capable of generating electricity with a temperature difference of 1°C, the company said. "
[11:01:20] <fragalot> note the difference between mW and MW
[11:01:26] <L84Supper> did Dean Kamen have an engine that ran on just about any garbage you could burn?
[11:01:27] <Jymmm> 2
[11:01:52] <fragalot> hell not even that, the other site said kW
[11:01:58] <fragalot> how do you get things that wrong
[11:02:19] <Jymmm> fragalot: you rob a mobster
[11:02:32] <fragalot> Jymmm: i'm too much of a pansy to try and do that
[11:02:39] <Jymmm> heh
[11:02:56] <L84Supper> http://alfin2100.blogspot.com/2009/05/dean-kamens-magic-stirling-engine.html
[11:03:22] <FinboySlick> L84Supper: There's some success with plasma gasification. That's not a typical garage setup though.
[11:04:12] <fragalot> stirling engines do run on anything that produce heat, but what they neglect to mention is that they're terribly inefficient
[11:04:13] <Jymmm> Tecan: That's interesting. I'd like to see a smaller model (in a controlled test room, shed?) to be able to test different configs. Like lego rocket mass heater
[11:04:20] <fragalot> you're much better off with a small steam engine
[11:04:33] <FinboySlick> I think they just (or are about to) completed a project in florida. Japan has been doing it for a while.
[11:05:27] <L84Supper> whats the highest efficiency natural gas electric generator?
[11:06:11] <Jymmm> 8hours per gallon (gasoline) == Honda EU2000i
[11:06:22] <Jymmm> Can be setup as Tri-fuel
[11:06:55] <Jymmm> at 50% iirc
[11:07:48] <L84Supper> 8hours per gallon at what output load continuous?
[11:08:22] <Jymmm> Well, at 100% it's 2KW, so at 50% I'd say that would be 1KW
[11:08:46] <Jymmm> or slightly less
[11:09:09] <L84Supper> 8hours per gallon with a continuous 2000W load
[11:09:19] <Jymmm> I said at 50%
[11:09:30] <L84Supper> 1000w load then
[11:10:08] <L84Supper> 8KW/H per gallon
[11:10:31] <L84Supper> sorry 8kwh per gallon
[11:10:50] <Jymmm> Google it, there are real life test results otut there
[11:10:54] <fragalot> L84Supper: This is the one you want: http://www.youtube.com/watch?v=R9i8_CFZtfo
[11:11:02] <L84Supper> yeah, in the middle of that
[11:11:18] <fragalot> xD
[11:14:55] <Jymmm> L84Supper: http://www.rv.net/forum/index.cfm/fuseaction/thread/tid/24022161/gotomsg/24963199.cfm
[11:15:49] <fragalot> http://www.youtube.com/watch?v=ALFYm_6IlX8 this is literally the coolest lightbulb i've ever seen
[11:16:53] <Jymmm> fragalot: lick it!
[11:18:32] <L84Supper> gas here is $3.70/gal, so $0.46 per kwh
[11:18:51] <Jymmm> Tecan: Now, be sure to incorporate an array of T-Coolers into your rocket heater =)
[11:18:55] <Loetmichel> sooo, done, machine clean again and optimal adjusted... side effect: G0 is now 2100mm/min instead of 1500 mm/min ;-) -> http://www.cyrom.org/palbum/main.php?g2_itemId=14040
[11:19:04] <fragalot> Jymmm: :D
[11:19:25] <fragalot> Jymmm: been zapped with 60kV before, and that day I learned that I never, ever, want that to happen again.
[11:19:33] <Loetmichel> now i will make some new covers for the x, y and z linear ways and then do some work for the company. ;-)
[11:19:46] <Jymmm> fragalot: Ya think???
[11:20:42] <Jymmm> fragalot: Just goes to show that you shouldn't be sticking your tounge into places
[11:20:55] <L84Supper> http://jalopnik.com/dean-kamen-stirling-engine/ 4 years ago
[11:21:25] <Loetmichel> fragalot: 60kV? and still standing? what was the current limit? 2mA? ;-)
[11:21:37] <Tecan> jymmm whats a t-cooler ?
[11:21:44] <L84Supper> http://www.dekaresearch.com/stirling.shtml still can't buy one
[11:22:29] <Tecan> http://matteranenergy.com/
[11:23:07] <Jymmm> Tecan: It produces electricity from thermal differential. It can also general heat/cold from electricity. (Those 12V coolers you see in the sporting good store)
[11:23:11] <Tecan> the patent on that thing is amazing
[11:23:21] <Tecan> thermo syphon, its pumpless
[11:24:44] <fragalot> Loetmichel: 10mA, only went through my left arm thankfully
[11:24:49] <L33TG33KG34R> I don't remember who, but there was someone here that offered me some extrusion from canada for raising my CNC. Who was that? I just need some extrusion from Canada to raise my CNC. I am looking for 5' of 1545 extrusion. Could someone please help me out?
[11:25:06] <Jymmm> Tecan: http://www.tetech.com/Peltier-Thermoelectric-Cooler-Modules.html
[11:25:29] <Jymmm> Tecan: http://www.acktechnology.com/Thermoelectric%20Cooling%20Module.htm
[11:25:35] <Tecan> i found some peltier coolers on ebay 60 watt and bought 4 for 10 bux or something
[11:25:47] <Loetmichel> fragalot: that hurt, didnt it?
[11:26:16] <fragalot> Loetmichel: no kidding
[11:26:28] <Jymmm> Tecan: https://www.youtube.com/watch?v=Zl_AvKkCFQk
[11:26:30] <fragalot> I felt it for a week
[11:26:46] <Loetmichel> fragalot: hrhr, i know that feeling ;-)
[11:26:57] <L84Supper> matteranenergy.us is more BS, no specs
[11:27:44] <Loetmichel> was onl 8kV, but about 50mA... luckily i survived it despoite going from left to right arm... ;-)
[11:28:53] <fragalot> Loetmichel: ouch, got lucky there
[11:29:33] <Loetmichel> right
[11:29:59] <L84Supper> http://www.nextenergynews.com/news1/next-energy-news-toshiba-micro-nuclear-12.17b.html from '07
[11:32:33] <L84Supper> maybe you just have to threaten to sell an efficient low cost thorium reactor and you'll either have an accident or get bought out
[11:33:10] <Jymmm> Tecan: I mean, if you are going to go thru the trouble of building a rocket mass heater, incorporating TE Coolers if for nothing else free lighting or recharging a battery doesn't seem like a bad idea.
[11:33:34] <Tecan> no for sure not
[11:33:50] <Tecan> have them sitting on the top as a hotplate before the pot of water
[11:34:22] <Jymmm> Tecan: Well, they need a heatsink too on the cold side.
[11:35:02] <Jymmm> Tecan: cold water pipe maybe
[11:35:32] <Tecan> youd have more hot water than you know what to do with :)
[11:35:38] <Tecan> steam power
[11:36:28] <Jymmm> Well, drawing off too much from the rocket, would reduce it's effeciancy I think
[11:36:42] <Jymmm> it's just a balance between them
[11:37:44] <L84Supper> http://www.telegraph.co.uk/finance/comment/ambroseevans_pritchard/9784044/China-blazes-trail-for-clean-nuclear-power-from-thorium.html should be on Alibaba in few years :)
[11:38:13] <Jymmm> it already is, but min qty 100K units
[11:38:31] <Jymmm> and shipping is 100000000000000000X more
[11:39:12] <Jymmm> oh, it's Sunday.

[12:32:01] <L84Supper> http://www.use-enco.com/CGI/INPAGE?PMPAGE=/specials/319-9733 picked one up with a bad motor for $1k, the gears are about as soft as butter
[12:32:43] <L84Supper> and the included wiring diagram does not match the actual wiring
[12:34:52] <andypugh> At least you won't be throwing away nice parts if you CNC it :-)
[12:35:31] <L84Supper> I have to rewire it anyway
[12:37:22] <L84Supper> it looked like they used a forklift to move the lathe but forgot to unhook the wiring first

[12:41:28] <L84Supper> they used to store it all here but when the economy stalled they just broker from seller to buyer
[12:42:44] <tjtr33> i'd appreciate it if you lemme know of used cnc edm. a control-less machine might be nice.
[12:42:54] <tjtr33> thx
[12:43:24] <L84Supper> I came across 2 for free last summer, you just had to pay for removal and trucking
[12:44:22] <L84Supper> tjtr33: are you in the midwest?
[12:44:27] <tjtr33> elgin
[12:44:59] <L84Supper> I came across a few in Elk Grove as well
[12:45:12] <tjtr33> hehe worked in egv for years
[12:45:15] <L84Supper> with bad controls
[12:45:39] <tjtr33> oh like at gray machinery? just repaired 2 dead okomotos down in ky form them
[12:46:28] <L84Supper> in small shops, guys that use them/buy/sell but don't know how to fix
[12:46:28] <tjtr33> 3 axis edm sinkers
[12:46:59] <L84Supper> actually heading to Carpentersville in a few minutes
[12:47:05] <tjtr33> in small shops, guys keep them running anyway they can, and repairmen eat oatmeal 3x a day :(
[12:47:09] <L84Supper> small world
[12:47:10] <tjtr33> have fun
[12:48:28] <L84Supper> http://chicago.craigslist.org/chc/tls/3563737543.html a little pricey
[12:50:22] <tjtr33> handsvedt. will run on 110 if anyones interested, good, sturdy, but completely manual, worth about 1k on street
[12:50:58] <tjtr33> thx, not my stuff tho, if its was cnc then its ready to cnc, v&flat ways & bibs are ng
[12:51:07] <tjtr33> gibs
[12:52:19] <tjtr33> 10k! hahaha
[12:53:41] <L84Supper> machine tools are cheap in China, same for welders
[12:54:05] <L84Supper> 150A TIG for $100
[12:54:24] <L84Supper> 400 A stick, $160
[12:55:36] <L84Supper> if it lasts a year and buy a new one for 5 it's still less than new MIller
[12:56:15] <fragalot> they're cheap for a reason :P
[12:56:26] <fragalot> L84Supper: a miller should outlast you
[12:57:37] <L84Supper> over there they strap them on their cycle and go to work
[12:57:59] <fragalot> I've got a cheap Contimac TIG/stick combo 160A, and a 160A LasTek tig/stick combo
[12:58:15] <fragalot> the lastek one costed around 5x what the contimac one did, but i'll take the lastek with me any day
[12:58:30] <fragalot> it just works so much nicer
[12:59:03] <fragalot> (lastek is a Rehms rebrand)
[12:59:18] <L84Supper> if I need two pieces of metal stuck together I'll use just about anything, but if i want a nice pattern it's usually on a good welder blue/red or white
[12:59:47] <fragalot> it's not only the pattern, it's how stable and consistent the arc is
[12:59:55] <andypugh> I always liked the look of the Rehm Tiger, but not the price :-)
[12:59:55] <fragalot> and how tight it can keep it
[13:00:03] <fragalot> andypugh: yeah :P there's one thing I really dislike about it though
[13:00:14] <fragalot> andypugh: it's perfect, EXCEPT for the pulse setting not going faster than 10Hz
[13:00:24] <fragalot> so it's too fucking annoying to use and never gets used
[13:00:35] <andypugh> I like to have a welder that is motorbike portable :-)
[13:01:01] <L84Supper> it's crazy the stuff you see on bikes there
[13:01:29] <L84Supper> or a moped-like with a trailer piled with pipe 2 meters high
[13:01:29] <andypugh> fragalot: I'll give you £100 for the Tiger :-)
[13:01:31] <fragalot> I've got the old model of this thing that I take with me to places where I just KNOW it's going to take a beating: http://www.contimac.be/nl/product/412342232671457/tig/tig-dc-professional/tig-160-dc-lift
[13:02:01] <fragalot> it works, but it's a right bugger to keep a tight arc with it
[13:02:16] <fragalot> andypugh: lolno
[13:02:46] <tjtr33> andypugh, mount the welder in the side car of a Chiang Jiang ( chinese R75 )
[13:03:42] <fragalot> andypugh: I paid 2500 euro for the tiger, including a spare torch, full compact argon bottle (don't know the size, but it's about 1 meter tall), SMAW torch, 3M helmet, goat leather gloves, the box, and a stack of 1613, and 307 TIG rods
[13:03:48] <fragalot> andypugh: can't complain ^_^
[13:07:55] <andypugh> I ended up with a "Rehmann" welder from eBay. (I found that the Italians bid lowest ;-)
[13:08:27] <andypugh> It's fine. I have only actually used it a dozen times in the 3 years, so I am glad i didn't pay more.
[13:09:24] <tjtr33> andypugh, they were r71 copies from dies taken from the russians http://www.changjiangunlimited.com/03-0506-402.jpg
[13:09:39] <andypugh> Yes, I am aware of them.
[13:10:11] <andypugh> A rubbish copy of a rubbish bike..
[13:11:00] <andypugh> I have one of these in boxes. One day it might roll again: http://motorbike-search-engine.co.uk/classic_bikes/NERACAR_MODEL_B.jpg
[13:12:04] <archivist> I want a ride on it
[13:15:01] <andypugh> So do I :-)
[13:16:20] <tjtr33> neracar! museum stuff sit on it like on a sofa
[13:24:33] <mikegg> If I put two 12v fans in series with a 24v power supply, will I fry something?
[13:25:11] <archivist> depends if the fans are identical and some luck
[13:26:10] <mikegg> ok, they are the same. Not big or expensive. Just wondering if it was worth a shot...
[13:26:25] <mikegg> I seem to be frying a lot of things lately
[13:27:44] <gene77> Ok, wiki falls over again...
[13:28:02] <archivist> at initial turn on one may take more current than the other so the voltage will not be balanced, the other will be over voltage to an unknown extent
[13:28:07] <gene77> Max limit on a lathe, is in radius, or diameter?
[13:28:18] <pcw_home> I'd worry about what power was first applied but they should balance when running (they might need a bypass cap across each one)
[13:28:38] <pcw_home> s/what/when/
[13:29:48] <archivist> I suppose a couple of 12.something zeners could help
[13:29:55] <mikegg> whats the bypass cap do? dump some current to ground / next fan when you first cut power on?
[13:31:15] <pcw_home> The fans are designed to run from a low impedance supply, you lose this when you have another fan in series
[13:32:14] <archivist> here's hoping the caps are balanced better than the motors
[13:32:30] <pcw_home> But this is just guessing (where does the inductive energy go what a winding is turned off)
[13:32:56] <pcw_home> normally back into the power supply...
[13:33:10] <mikegg> argh? I thought impedance is an AC term. When working with DC it's just resistance
[13:33:23] <gene77> testing says radius
[13:33:45] <pcw_home> DC fans represent a dynamic load
[13:34:20] <pcw_home> They both absorb and dump energy back into the power supply
[13:34:33] <mikegg> gotcha
[13:34:54] <mikegg> but in this case that could be the other fan
[13:35:25] <mikegg> so if the phases align the wrong way you could get problems
[13:35:27] <pcw_home> And because they are usually very cheap I would not expect them to have much if any bypass capacitance
[13:37:07] <mikegg> what size bypass cap would be appropriate?
[13:37:15] <archivist> one could make a low impedance mid rail with an opamp and capacitors or something
[13:38:40] <pcw_home> Or if you have spares do the smoke experiment :)
[13:38:44] <mikegg> I'd have an easier time selling myself as a day laborer long enough to buy 24 volt fans
[13:39:54] <tjtr33> is the fpga on m5i20 Spartan 3? ( will Pong P Chu's book FPGA Programming by vhdl examples be useful? )
[13:41:03] <pcw_home> 5I20 is spartan2, 5I21,22,23, 7I43 are Spartan3, 5I25/6I25/7I80 are Spartan6
[13:41:11] <archivist> pnp and an npn two diodes and two resistors and a couple of caps
[13:41:58] <tjtr33> thx just found it was 2
[13:42:18] <pcw_home> or just try in series (I wonder what the absolute max the will take is?)
[13:42:51] <pcw_home> 5I20 is quite old (last of the 5V tolerant FPGAs)
[13:43:05] <archivist> if one fails short the other will go faster :)
[13:44:03] <pcw_home> Reminds me of when i put my lab supply on one of those barking puppy toys...
[13:45:21] <archivist> I have destroyed a few things trying "what if I do"
[13:46:50] <tjtr33> pcw_home, hehe m5i20's and D510's were all the rage not long ago. the 7i43 looks interesting, but i suppose the 5i25 is the new workhorse
[13:47:41] <fragalot> archivist: haven't we all?
[13:48:30] <archivist> starts when as a kid you take things apart :)
[13:50:59] <fragalot> I remember saying "I'll fix it for you!" as a kid... and then bricking it completely
[13:51:02] <fragalot> xD
[13:52:38] <mikegg> well, so far so good. Would it make a difference that it's on a regulated power supply? I'll leave em running for a bit....
[13:55:46] <pcw_home> tjtr33 yes 5I25/6I25 and 7I80 and variants when its supported
[13:59:16] <tjtr33> pcw_home, what might you recommend for studying fpga programming? i need special triggerable pulsers down to 2uS or less periods. and what i really need might change, so dev tool is needed.
[14:00:24] <tjtr33> maybe i should just use the 5i20 if its that much behind the new stuff
[14:00:28] <pcw_home> Well chose a language and get a good book
[14:00:43] <tjtr33> yah Cho & Vhdl
[14:00:50] <tjtr33> thx
[14:01:49] <fragalot> the only trick you need to keep in mind when it comes to FPGA's is that you're describing hardware, not programming software
[14:02:02] <fragalot> it might sound obvious but the way you do things is significantly different
[14:02:04] <pcw_home> I have designed guide to VHLD that pretty good
[14:02:10] <pcw_home> designers
[14:02:18] <fragalot> once you make that click, it's pretty easy :)
[14:02:46] <pcw_home> yes its parallel (but I started from a hardware perspective so it was easy for me)
[14:04:45] <pcw_home> The thing that was hard for me to grasp at first was the serial program structures in the HLL (like loops) were only compile time generators of parallel logic
[14:45:25] <gene77> Is there a way to clear all 'touch offs' without a shutdown and deletion of linuxcnc.var?
[14:45:36] <spiderdijon> hey, does anyone have a huanyang vfd here? I need some advice on grounding.
[14:46:12] <ReadError> is that the 300$ one they sell with the spindle on ebay?
[14:46:25] <spiderdijon> yus :)
[14:46:41] <ReadError> yea i saw in a vid, they arent actually grounded
[14:46:46] <ReadError> you have to do it manually
[14:47:28] <spiderdijon> ah I had come to the same conclusion, can you remember the vid link?
[14:49:15] <spiderdijon> sad thing is I'm still experiencing some nasty interference when the spindle is running, seems to stall my steppers frequently
[14:49:50] <spiderdijon> short, shielded spindle cable which is running separately from the stepper lines
[14:49:56] <ReadError> yea hold on
[14:50:52] <ReadError> http://www.youtube.com/watch?v=pBHMjJ7azzE
[14:54:59] <mrsun> unconnected ground
[14:55:03] <mrsun> how nice of them :P
[14:58:38] <Loetmichel> mrsun: normal. Was the same on mine
[15:00:09] <mrsun> well not very normal as its dangerous ...
[15:00:10] <mrsun> :P
[15:04:49] <Loetmichel> mrsun: even better: on mine the green one was a hase and the blu wire was open ;-)
[15:04:57] <Loetmichel> phase
[15:05:34] <mrsun> ... :P
[15:05:42] <mrsun> quality
[15:13:17] <spiderdijon> ah, the interference is flowing along the spindle trigger wires
[15:13:40] <spiderdijon> DCM and FOR if anyone is interested
[15:16:47] <spiderdijon> looks like im going to have to RS-485
[15:34:16] <Icekiller> its my birthday w00tw00t :P
[15:35:28] <L33TG33KG34R> HBD!
[15:36:27] <Icekiller> thx
[15:38:11] <spiderdijon> :D
[15:41:36] <spiderdijon> also turns out it is my water pump

[15:53:57] <fragalot> andypugh: ahaha
[15:55:35] <fragalot> I didn't know dilbert had animated stuff
[16:05:35] <L33TG33KG34R> hehehe
[16:06:42] <L84Supper> r00t4rd3d: and hp45 ink isn't the most expensive inkjet ink
[16:08:06] <skunkworks> sure not - We have some large format printers that the ink is quite expensive
[16:10:02] <L84Supper> I think that chart assumed the price of the hp45 ink sold in the cartridge ~40ml at list price
[16:10:35] <L84Supper> it only costs about $5 a liter to make
[16:14:34] <andypugh> What does squid ink cost?
[16:14:48] <toastyde2th> minecraft or irl
[16:15:08] <andypugh> Either, but please answe rhetorically :-)
[16:15:43] <andypugh> (Kraken's blood is the most valuable commodity in YPP Puzzle Pirates)
[16:16:01] <L84Supper> anything with pixie dust
[16:16:25] <toastyde2th> squid ink is pretty boring except it can be hard to find if you spawned nowhere near any large bodies of water
[16:16:43] <toastyde2th> the only thing that makes it semi-rare is that farming it is nearly impossible
[16:16:46] <L84Supper> same for faerie or fairy
[16:17:04] <toastyde2th> so you never really have an overabundance of it, it's always at the same level
[16:17:08] <andypugh> http://yppedia.puzzlepirates.com/Kraken's_blood
[16:18:37] <andypugh> I spent months getting enough together for a complete black outfit. I had forgotten all about that until I asked that question.
[16:18:58] <L84Supper> is that anything like having your underwear ride up your Kracken?
[16:19:21] <andypugh> In fact, I am going to log in to the game for the first time in months to see if it has been eaten by moths yet :-)
[16:36:43] <DJ9DJ> gn8
[16:38:13] <Jymmm> andypugh: WOW! You around on a weekend (or is it Monday there already?)

[16:46:28] <andypugh> Jymmm: Just got back from 14 days in Lapland
[16:47:26] <andypugh> skunkworks: Too much overhang! Why do they do that?
[16:48:44] <L84Supper> andypugh: how was the weather? besides cold
[16:48:52] <andypugh> Not cold enough
[16:49:33] <L84Supper> i thought you guys (norther europe) got buried in snow last month
[16:49:52] <andypugh> We wanted -30 and got -10 though.

[18:06:10] <tjb1> Look at that horrible posture
[18:06:19] <tjb1> uneven
[18:06:28] <tjb1> going to be painful landing
[18:06:31] <tjb1> what a noob
[18:06:45] <r00t4rd3d> soft sand
[18:07:26] <tjb1> still a bad way to land
[18:07:41] <ReadError> got me some 1/4" endmills too
[18:07:45] <ReadError> never cut with something so large
[18:07:50] <ReadError> should eat right through aluminum

[18:08:47] <r00t4rd3d> 660 has carb, 700 FI
[18:09:08] <alex4nder> who is racing 250 ninjas?
[18:09:12] <r00t4rd3d> lol
[18:09:19] <tjb1> Yeah I know 660 has 2 carbs...
[18:09:41] <tjb1> carbs > fi
[18:11:16] <tjb1> fi is for people like r00t4rd3d that dont know how to tune carbs ;)
[18:15:42] <Jymmm> Or those that don't like to stall when at 30+ degree incline
[18:16:19] <r00t4rd3d> roll it and keep on going instead of waiting
[18:16:34] <Jymmm> tjb1: And you know where you can put your float valve!
[18:17:09] <Jymmm> r00t4rd3d: No, no rolling =)
[18:17:49] <r00t4rd3d> i never crashed that 700 though, tried
[18:18:24] <r00t4rd3d> with the ethanol in the gas the fi took away a headache
[18:18:29] <Jymmm> tjb1: Can you tell I'm just not fond of carbs =)
[18:20:15] <r00t4rd3d> id rather have carbs on my toys
[18:20:57] <Jymmm> if ya can figure out how to run moonshine in the engine... NOW we're talking!
[18:21:55] <Jymmm> Make my own fuel and have drunken chicken all at the same time!
[18:27:33] <r00t4rd3d> im gonna dremel out my intake and exhaust ports
[18:27:44] <Jymmm> dremel?! lol
[18:28:21] <r00t4rd3d> just clean up the excess cast
[18:28:47] <r00t4rd3d> besides a small file its the only thing that will fit down in there
[18:28:58] <Jymmm> car?
[18:29:08] <r00t4rd3d> no a small engine
[18:29:13] <Jymmm> ah
[18:29:23] <r00t4rd3d> http://i.imgur.com/2Phhw6h.jpg
[18:29:58] <tjb1> You stall out on 30 degrees?
[18:30:04] <tjb1> you dont know hwo to tune a carb then
[18:31:06] <Jymmm> and dont care either
[18:33:42] <tjb1> I know you aren't fond of gas to begin with ;)

[18:34:41] <ReadError> how well do you suppose that would work with g10?
[18:34:44] <ReadError> (FR4)
[18:34:48] <ReadError> finish wise...
[18:39:52] <r00t4rd3d> those work good
[18:40:08] <r00t4rd3d> probably my most used
[18:40:43] <ReadError> probably not so much for aluminum though, i would think chip clearning would suck
[18:41:10] <r00t4rd3d> they grind more then chip
[18:42:14] <r00t4rd3d> a regular wood bit throughs chips all over but those make more of a powder

[18:45:27] <r00t4rd3d> stick to down cut bits
[18:45:55] <r00t4rd3d> if you get any fluted ones
[18:46:49] <ReadError> tjb1, i used to get those from amazon
[18:46:54] <r00t4rd3d> I got a up cut bit from lowes and that fucker makes a giant mess
[18:46:59] <ReadError> but g10 is an endmill killer
[18:47:25] <ReadError> so i spend 3$ on one, use it and toss it
[18:48:18] <r00t4rd3d> ive only got 2 .125 carbides like that and ive cut tons of oak with them
[18:49:53] <ReadError> yea i can do a bunch of aluminum
[18:49:59] <ReadError> g10/cf, murders em
[18:51:15] <r00t4rd3d> i got like 20 .0625 carbides

[18:59:02] <r00t4rd3d> thats nice
[19:00:27] <r00t4rd3d> oh thats the 1/2 shank one
[19:00:42] <r00t4rd3d> http://www.amazon.com/CMT-858-001-11-Cutting-Diameter-16-Inch/dp/B000P4NSYG/ref=sr_1_2?ie=UTF8&qid=1360543542&sr=8-2&keywords=cmt+router+60
[19:00:48] <r00t4rd3d> 1/4 shank :)
[19:00:48] <Jymmm> look at 120 degree
[19:01:32] <Icekiller> anyone here in europe have a cheap hf spindle for sale ^^ (its my birthday soo xD maybe i'll get lucky ehehe)
[19:02:02] <r00t4rd3d> no but i got a bridge ill sell ya
[19:02:34] <ReadError> weeeednesday plz hurry
[19:02:49] <ReadError> 4 days of ass busting to get this router together
[19:03:02] <r00t4rd3d> whats the rush
[19:03:14] <ReadError> i got people waiting ;)
[19:03:21] <ReadError> my 1st run is 300$
[19:03:34] <r00t4rd3d> in your cost cause you are gonna fuck up
[19:03:40] <ReadError> lol
[19:03:52] <ReadError> well im not going to put down the material until its tested and tuned
[19:04:10] <Valen> what acceleration do people have for their router style machines?
[19:04:19] <r00t4rd3d> i did test cuts in scrap on everything i sold for awhile
[19:05:07] <ReadError> plus things should be easier now that i have a better clue about what im doing ;)
[19:05:24] <ReadError> my biggest hurdle the 1st time was making gcode in cam software
[19:05:29] <ReadError> i got that down pretty good now
[19:06:23] <r00t4rd3d> http://www.ebay.com/itm/1-4-Shank-Engraving-Router-Bit-and-Inserts-In-Groove-/370518349411?pt=LH_DefaultDomain_0&hash=item56449d5663
[19:06:26] <r00t4rd3d> buy me that
[19:07:34] <ReadError> Valen, i have no idea ;/
[19:08:09] <Valen> I'm just trying to design the new mill
[19:08:20] <Valen> router rather
[19:08:21] <r00t4rd3d> my machine does 18ipm but thats cause i have a tb6560 controller
[19:08:30] <Valen> 18ipm?
[19:08:42] <r00t4rd3d> inch per min
[19:08:46] <Valen> yeah
[19:08:48] <Valen> but 18?
[19:09:03] <r00t4rd3d> tb6560 sucks
[19:09:09] <Valen> sails could outrun it in a james bond style escape sequence
[19:09:33] <r00t4rd3d> if anyone wants to donate me their old g540 ill take it
[19:10:07] <ReadError> awww
[19:10:12] <ReadError> you need the g540
[19:10:17] <r00t4rd3d> i know
[19:10:22] <Valen> I'm going servo drives
[19:10:27] <Valen> dmm-tech ftw
[19:11:04] <ReadError> servos seem complicated ;/
[19:11:20] <Valen> not really
[19:12:29] <r00t4rd3d> i could probably do 80-100ipm with a 540
[19:12:53] <r00t4rd3d> i couldnt even imagine it
[19:14:08] <Valen> heh, the motor I'm designing with at the moment is hitting 1574 IPM
[19:14:32] <Valen> though it should 2165IPM without too much stress
[19:15:11] <r00t4rd3d> https://www.sparkfun.com/products/10847
[19:15:15] <r00t4rd3d> those are the motors i have
[19:15:27] <r00t4rd3d> not sure how fast they would go
[19:15:28] <Valen> I'
[19:15:35] <Valen> I'm looking at 750W servos
[19:16:47] * skunkworks is running 4kw peak servos/drives ;)
[19:17:14] <Valen> nice skunkworks
[19:17:22] <Valen> what acceleration are you getting on what?
[19:17:40] <skunkworks> heh - big old machine - accelleration set pretty low
[19:17:47] <skunkworks> Make for cutting force - not speed
[19:17:51] <skunkworks> *made
[19:18:03] <skunkworks> 16 tons of peak cutting force
[19:20:10] <skunkworks> http://www.youtube.com/watch?v=pOHL_KlUdqw
[19:21:58] <Valen> I just keep coming up with accelerations like 3G
[20:37:12] <r00t4rd3d> tjb1, http://landoftechnology.com/2013/the-nexus-7-in-car-ui-guide-projectn7-by-mr_bridger/
[20:37:21] <r00t4rd3d> he has included the files at the bottom
[20:37:47] <tjb1> how does speedo work?
[20:37:53] <r00t4rd3d> obd
[20:38:10] <tjb1> :/
[20:38:25] <tjb1> aint nobody got time for that
[20:38:37] <tjb1> I use apex launcher also
[20:38:42] <tjb1> not turning dock off
[20:38:58] <r00t4rd3d> https://play.google.com/store/apps/details?id=com.binarytoys.speedometer&hl=en
[20:39:10] <r00t4rd3d> that is what he is using for speedo
[20:40:09] <r00t4rd3d> i guess its gps only
[20:42:36] <pcw_home> A good one could use the accelerometers for dead reckoning for better responsiveness
[20:43:16] <r00t4rd3d> https://play.google.com/store/apps/details?id=com.vinwap.kitt
[20:43:19] <r00t4rd3d> lol
[20:44:56] <Jymmm> pcw_home: accelerometers?! Please, what you think this is the 20th century or something??? WHERE'S MY HOVERCRAFT DAMNIT!!!!!
[20:46:12] <pcw_home> wheres my jet pack for commuting to work?
[20:46:38] <Jymmm> pcw_home: Commute?! You don't commute
[20:47:18] <pcw_home> Popular Science was wrong??? Oh No
[20:47:43] <L84Supper> maybe you left it in your flying car
[20:48:05] <Jymmm> pcw_home: No, I'm saying YOU don't travel far either from home/work to consider that a "commute".
[20:49:19] <pcw_home> Come on, it take 8 Minutes should be able to shorten that to 1 with a jet pack
[20:49:39] <L84Supper> are you near water?
[20:49:45] <Jymmm> when you get to 8 hours, we can talk
[20:49:53] <Jymmm> or even 80 minutes
[20:50:26] <L84Supper> http://www.youtube.com/watch?v=7-KczCp0OQ4 JetLev
[20:50:40] <Jymmm> L84Supper: land, not water.
[20:50:53] <Jymmm> or water AND land.
[20:51:24] <Jymmm> and air!
[20:51:42] <L84Supper> I though you guys walked or rode bikes to work while eating whole grains without gluten to work
[20:51:55] <Jymmm> Not me, that's pcw_home
[20:52:24] <pcw_home> Sometime I walk in the summer but its a lousy walk
[20:52:27] <Jymmm> I drive an SUV, eat dead flesh
[20:53:10] <L84Supper> http://www.youtube.com/watch?v=O7LyFtOj1k0 jet pack, but I guess it doesn't have enough lift for takeoff
[20:53:28] <Jymmm> AeroLight
[20:53:59] <Jymmm> Only issue is the FAA limits to 5 gallons of fuel
[20:54:17] <Jymmm> iirc
[20:54:28] <L84Supper> belly fat powered for the win
[20:55:24] <pcw_home> L84Supper: have you seen the ODROID SBCs ?
[20:55:59] <L84Supper> by hardkernel?
[20:56:26] <pcw_home> Yeah using the Samsung quad core 1.7 GHz CPU
[20:56:46] <L84Supper> they make 1k boards and then move on to the next design
[20:57:06] <pcw_home> Yeah looks like development boards
[20:57:29] <L84Supper> http://www.hardkernel.com/renewal_2011/products/prdt_info.php
[20:57:48] <L84Supper> that stacked connector should optional as a header
[20:58:11] <L84Supper> it's another board layout that could only be made worse by adding a seat or handlebars as a feature
[20:59:56] <L84Supper> pcw_home: how about using HDMI as an interface to a FPGA
[21:00:06] <pcw_home> I guess the CPU needs a heatsink (5W?)
[21:00:55] <L84Supper> hdmi ethernet
[21:01:24] <tjb1> r00t4rd3d: gps works on nexus without internet?
[21:01:40] <Jymmm> gps does, no maps
[21:01:59] <pcw_home> how man chipsets support it (HDMI 2.0?)
[21:03:06] <pcw_home> hdmi ethernet is fairly clever though (100mbit full duplex 1 wire)
[21:03:44] <L84Supper> or the digital audio channels
[21:04:03] <Jymmm> I know it's bad acting, but damn... How many mags do they have to go thru to kill a water jug? http://www.youtube.com/watch?v=wdjk_W8nTno
[21:06:45] <r00t4rd3d> tjb1, yeah
[21:07:04] <L84Supper> http://www.samsung.com/global/business/semiconductor/minisite/Exynos/data/Exynos4%20QUAD.pdf
[21:07:22] <r00t4rd3d> you can also use google maps offline but you have to predownload the area you want
[21:07:25] <L84Supper> http://www.samsung.com/global/business/semiconductor/file/product/Exynos_4_Quad_User_Manaul_Public_REV100-0.pdf
[21:07:50] <r00t4rd3d> some gps apps have satellite overlays also
[21:08:12] <L84Supper> HDMI 1.4
[21:08:22] <r00t4rd3d> fuck samsung
[21:08:55] <tjb1> what is wrong with samsung
[21:10:29] <r00t4rd3d> they are one of the main contributors to the fragmentation of Android.
[21:11:47] <r00t4rd3d> their update deal is horrible
[21:12:17] <L84Supper> http://www.ubergizmo.com/2013/01/samsung-exynos-5-octa-specs/
[21:12:26] <r00t4rd3d> 10 people in a room have samsung android device and they all on different versions of android
[21:13:16] <r00t4rd3d> you would think all Samsung Galaxy SII's are the same right?
[21:13:19] <r00t4rd3d> they are not
[21:13:32] <tjb1> piss on samsung updates
[21:13:37] <tjb1> root and CM10.1
[21:14:11] <r00t4rd3d> only reason i sold my s2 and got a nexus 7
[21:14:20] <r00t4rd3d> to stay uptodate
[21:15:12] <r00t4rd3d> Letting Tracfone decide when to update my phone cause samsung is a pussy who bends over to carries was a joke
[21:18:56] <pcw_home> the Exynos 4412 does say it has HDMI1.4 but of course it if it doe have Ethernet it uses the weird 1 pair PHY
[21:21:02] <tjtr33> on the http://cubieboard.org/buy/ page it says "* Taiwan is also part of China." thats gotta PO the Taiwanese!
[21:21:47] <pcw_home> I would think so
[21:22:25] <L84Supper> relations have been better the past few years but even people in China don't think of them as part of China
[21:23:00] <pcw_home> The 4412 is a 0.4MM BGA (I was looking for a SDIO level shifter and found they are only available in 0.4MM BGAs)
[21:23:02] <alex4nder> it's nice that they sell to iran
[21:23:02] <pcw_home> what a pain
[21:23:33] <pcw_home> Not something we can (or want to) do
[21:25:00] <L84Supper> you'll be able to print those boards yourself soon on the desktop
[21:27:49] <pcw_home> _That_ would be interesting
[21:31:18] <L84Supper> the printer also uses Linuxcnc
[21:33:52] <L84Supper> http://www.armbrix.com/
[21:51:26] <r00t4rd3d> 145?
[21:51:32] <tjb1> 215
[21:54:01] <r00t4rd3d> i would rather get a odroid
[21:54:08] <r00t4rd3d> http://www.hardkernel.com/renewal_2011/products/prdt_info.php?g_code=G135341370451
[21:54:12] <r00t4rd3d> $89
[21:54:23] <r00t4rd3d> and it has CyanogenMod support
[21:54:46] <r00t4rd3d> http://get.cm/?device=odroidu2
[22:09:17] <tjb1> what is that r00t4rd3d
[22:20:08] <Valen> lol at the size of the heatsink its mounted on
[22:21:03] <FinboySlick> I kind of like it.
[22:47:11] <r00t4rd3d> tjb1, its a arm board
[22:47:20] <r00t4rd3d> run android or ubuntu
[22:47:33] <r00t4rd3d> or any arm build
[22:48:49] <r00t4rd3d> http://www.ebay.com/itm/ODROID-Case-Laser-cut-Acrylic-for-Odroid-U2-/251221026455?pt=UK_Computing_DesktopComponents_RL&hash=item3a7df0a697
