[00:00:12] <Connor> zeeshan: You ever get your ballscrew figured out ?
[00:00:18] <Connor> why it was so hard to turn ?
[00:00:29] <zeeshan> connor too much preload on the fixed end
[00:01:02] <furrywolf> so 229/2 is 115ish...
[00:01:14] <zeeshan> furrywolf: pretty damn close to my actual number
[00:01:34] <furrywolf> now, you have it in parallel, which gives you double the torque, but a lower top speed... but they do tend to hit the axis around the same point.
[00:01:35] <zeeshan> so if i went to a 80v supply
[00:01:35] <Connor> Cool.. so you getting better speed now ?
[00:01:47] <zeeshan> Connor: back to what it was w/ the single ball nut
[00:01:54] <Connor> Good.
[00:01:57] <zeeshan> 120 ipm, but downgraded to 100
[00:01:59] <furrywolf> see, when you go by actual data, you get numbers that resemble what actually happens. :P
[00:02:01] <zeeshan> for safety
[00:02:09] <zeeshan> furrywolf: i know :P
[00:02:12] <zeeshan> test data ftw
[00:02:21] <zeeshan> theoretical should get you close though
[00:02:32] <zeeshan> but unfortunately i havent done much electrical theory
[00:02:36] <zeeshan> so i cant really comment on that
[00:02:39] <Cromaglious> http://www.youtube.com/watch?v=qGyMBkYgQsQ he really need to cnc this
[00:02:46] <furrywolf> there is no theoretical, there's only rough rules of thumb. the motor construction makes a huge difference.
[00:03:35] <furrywolf> there's steppers that'll spin tens of thousands of rpm...
[00:04:00] <zeeshan> man apparently that kl11078 took in ac
[00:04:04] <furrywolf> heh, my drivers even came with a warning that for certain models of stepper, the driver can drive them fast enough to burn the ball bearings.
[00:04:06] <zeeshan> so youdidnt need to run a seperate power supply
[00:04:07] <zeeshan> ~!!!
[00:04:43] <furrywolf> by running it in parallel, you get similar torque at 50V to what they measured in series at 100V.
[00:04:48] <zeeshan> this thing:
http://www.automationtechnologiesinc.com/products-page/kl-stepper-drivers/kl-11080-stepper-drive
[00:04:58] <furrywolf> you're getting more torque than the graph shows, not less
[00:05:19] <zeeshan> yea
[00:05:29] <zeeshan> i want moar speed though
[00:05:35] <zeeshan> need more voltage
[00:05:45] <zeeshan> fak if this thing ran 250 ipm
[00:05:47] <zeeshan> id be so happy
[00:05:54] <furrywolf> servos. :P
[00:06:00] <zeeshan> w/ steppers :P
[00:06:05] <furrywolf> steppers are not the technology of choice for high speed.
[00:06:09] <XXCoder> 16x gearing heh
[00:06:16] <XXCoder> much less precision :P
[00:06:21] <zeeshan> but we just saw at 6000 pps
[00:06:27] <zeeshan> it can do 350~ ipm
[00:06:34] <zeeshan> i should be able to do 250
[00:06:43] <furrywolf> gearing might not even help, unless you're gearing it down a lot, and want to undo that.
[00:06:45] <zeeshan> XXCoder: yea the damn tradeoff
[00:06:50] <furrywolf> <furrywolf> also, those are half-step pulses, so you need 1/400 rev/pulse.
[00:07:02] <furrywolf> note the graph explicitly says halfstep.
[00:07:09] <zeeshan> oh so 175 ipm max.
[00:07:16] <zeeshan> :-(
[00:07:22] * zeeshan goes back and sits in the corner
[00:07:38] <furrywolf> right. and that's max rpm with nothing on the shaft. you have a machine on the shaft, with friction and inertia.
[00:07:39] <zeeshan> honestly, if i were to go servo
[00:07:41] <zeeshan> id just buy another lathe
[00:07:43] <zeeshan> and sell this one
[00:08:05] <zeeshan> something with a spindle that can go to 6000 rpm at least
[00:08:18] <furrywolf> I got my steppers up to something like 5in/sec spinning a bit of electrical tape stuck to the end of the shaft. that doesn't mean the machine does that. :P
[00:08:28] <zeeshan> yes
[00:08:39] <XXCoder> heh yea it was real fast when I was testing
[00:09:14] <furrywolf> seems to me like your machine is operating about where you'd expect given the specs of the motors.
[00:09:43] <zeeshan> meh 100 ipm is ok
[00:09:46] <zeeshan> it gets the job done
[00:09:56] <zeeshan> ill finish making an enclosure for it
[00:09:57] <zeeshan> and be happy :)
[00:10:42] <zeeshan> its so hard to not always want more
[00:10:45] <zeeshan> damn human nature.
[00:11:30] <furrywolf> yeah, I have mine running around 100ipm too.
[00:11:58] <zeeshan> i think at speeds of 250 ipm
[00:12:04] <zeeshan> central lubrication becomes necessary
[00:12:27] <furrywolf> well, 80. need to deal with the non-balanced (doesn't even have a counterweight) handwheels making the machine walk around the floor problem to set it back higher.
[00:12:40] <zeeshan> bolt it down
[00:12:42] <zeeshan> :P
[00:12:49] <zeeshan> why do you still have handwheels?
[00:13:04] <furrywolf> it's on a rolling cart. I don't have enough space to have machines in fixed positions.
[00:13:11] <furrywolf> they're part of the bearings...
[00:13:13] <zeeshan> http://www.kijiji.ca/v-tool-other/st-catharines/leadwell-ltc-15-cnc-lathe/1057018854?enableSearchNavigationFlag=true
[00:13:15] <zeeshan> A LATHE
[00:13:16] <zeeshan> FOR CHEAP
[00:13:17] <zeeshan> !!!!!!!1
[00:13:46] <zeeshan> i bet i can lowball that
[00:14:00] <furrywolf> well,t he Y handwheel is at least. X and Z have independent bearings.
[00:14:19] <furrywolf> looks like a good toy.
[00:14:23] <XXCoder> pluse encoder issue
[00:14:28] <zeeshan> thats ok
[00:14:30] <furrywolf> also, I might do occasional manual machining too.
[00:14:33] <zeeshan> its a horoziontal bed lathe
[00:14:35] <zeeshan> with tool changer!
[00:14:38] <zeeshan> what ive been looking for
[00:14:44] <zeeshan> im looking up the center to center distance
[00:14:50] <XXCoder> finally, lots dilios lol
[00:15:05] <zeeshan> 4500 rpm spindle
[00:15:12] <zeeshan> 8000lb
[00:15:17] <zeeshan> 20hp spindle motor
[00:15:30] <zeeshan> 2.4" spindle bore, max machining length 20.47"
[00:15:33] <zeeshan> ok im buying this
[00:15:36] <furrywolf> dildos?
[00:15:43] <XXCoder> yea
[00:16:01] <XXCoder> man wish I can afford just buying $2000 lathe like so lol
[00:16:15] <furrywolf> I can't even afford a $200 mesa card for mine. :(
[00:16:36] <zeeshan> XXCoder: ive been saving money for one
[00:16:45] <zeeshan> i can only spend 1500
[00:16:47] <XXCoder> ahh yeah
[00:16:58] <zeeshan> imn really hoping he/she will take that.
[00:17:10] <zeeshan> its 30 min away too.
[00:17:16] <zeeshan> ill move my lathe to my dad's container
[00:17:18] <zeeshan> and put it for sale
[00:17:19] <furrywolf> point out you have cash and a way to transport it.
[00:17:44] <furrywolf> if they say no, say you'll give them the remaining amount when you sell your current lathe.
[00:18:00] <XXCoder> zeeshan: whats your current lathe
[00:18:04] <zeeshan> 12x36
[00:18:06] <furrywolf> bbl, wolfy bedtime. been jabbering on irc for an hour past when I should be asleep.
[00:18:09] <zeeshan> i bet i can sell it for 2k
[00:19:11] <zeeshan> fuck
[00:19:20] <zeeshan> if i get this, it will be another green machine
[00:19:28] <XXCoder> green power
[00:20:10] <Cromaglious> 10x44
[00:20:16] <tiwake> XXCoder:
http://en.wikipedia.org/wiki/List_of_house_styles
[00:20:42] <XXCoder> im telling ya, hypercube will do lol
[00:20:48] <furrywolf> that g-code ripper thing seems like it'd be better off as a kins module.
[00:20:48] <furrywolf> bbl
[00:21:03] <Cromaglious> but in modern speak it's about a 10x28
[00:21:22] <Jymmm> I dont' see freight container on the list
[00:21:49] <tiwake> list of... house styles?
[00:22:09] <tiwake> 'under the bridge' is not listed either
[00:22:14] <Jymmm> http://blog.builddirect.com/greenbuilding/wp-content/uploads/2011/08/container-house-quebec-2.png
[00:22:30] <XXCoder> http://www.countryliving.com/home-design/g1887/tiny-house/

[00:22:50] <XXCoder> http://earthship.com/
[00:22:58] <XXCoder> earthship is awesome, but lot work
[00:23:14] <tiwake> Jymmm: that looks like it would fall under post-modern :P
[00:23:22] <Jymmm> The "Tiny house" is all bullshit, just a design ptoject
[00:24:59] <Jymmm> I'm not even sure they wuld fit under two week vacation rental
[00:25:25] <zeeshan> man
[00:25:29] <zeeshan> im not going to be able to sleep now
[00:25:33] <zeeshan> i want this!
[00:25:44] <tiwake> there are a lot of wants
[00:25:45] <zeeshan> im so pissed i didnt catch it earlier
[00:25:58] <zeeshan> i usually search for "Cnc lathe" on my local classifieds
[00:26:09] <zeeshan> almost nightly. and i missed this by 2 days.
[00:26:15] <zeeshan> its gotten 98 views :(
[00:27:28] <tiwake> XXCoder: kinda interesting, I guess
[00:27:34] <tiwake> oh you know what isnt listed either
[00:27:41] <tiwake> missile silos... heh
[00:27:45] <XXCoder> yeah
[00:28:19] <tiwake> I've always wanted a missile silo
[00:28:51] <XXCoder> underground house if done properly at good locatuon means very stable house temperate so very low cooling/hgeating cost
[00:28:51] <Jymmm> tiwake: with fresh asbestos
[00:29:10] <tiwake> Jymmm: I can populate them if necessary...
[00:29:20] <Jymmm> ?
[00:29:31] <tiwake> populate the missile silo
[00:29:45] <Jymmm> with more toxicity than it already has?
[00:30:04] <tiwake> sure, assuming it has any
[00:30:14] <Jymmm> You're kidding, right?
[00:31:12] <Jymmm> an explortion proof, air tight, self contained, hole in the ground, with rocket fuel recipe made back int the 60/70's
[00:31:29] <Jymmm> Nooooooooo, no tocicity there ;)
[00:31:33] <tiwake> heh
[00:32:34] <Jymmm> tiwake: You could visit the one in Az, it's pretty cool
[00:32:53] <tiwake> there are a few around
[00:32:55] <Jymmm> http://digitalcartography.com/n0eq/discone.htm
[00:32:56] <tiwake> none in my area
[00:33:03] <tiwake> just some old bomb bunkers
[00:33:28] <Jymmm> and you can use the worlds largest discone antenna too (if your a ham)
[00:34:00] <Jymmm> http://www.titanmissilemuseum.org/
[00:34:48] <tiwake> http://www.missilebases.com/
[00:34:49] <Jymmm> top to bottom tour
http://www.titanmissilemuseum.org/view.php?pg=10
[00:35:10] <tiwake> how about an atlas E launch site
[00:35:24] <Jymmm> Yeah, I looked at a lot of the refits a ways back
[00:36:04] <Jymmm> I still think dropping a few continaers underground woul dbe more useful/realistic
[00:36:16] <Jymmm> and MUCH cheaper =)
[00:36:25] <tiwake> containers?
[00:36:39] <Jymmm> to make a silo livale would take at least $50k+++
[00:36:45] <Jymmm> shipping container
[00:36:47] <tiwake> oh yeah
[00:36:50] <Jymmm> shipping containers
[00:36:50] <tiwake> well
[00:37:08] <tiwake> there might be an off chance I would want to use it as intended
[00:37:21] <Jymmm> to launch a rocket?
[00:37:29] <tiwake> for example
[00:38:06] <Jymmm> eh, still old tech
[00:38:32] <tiwake> rockets havent changed though
[00:38:40] <tiwake> other than guidance systems
[00:38:47] <Jymmm> and fuel
[00:38:52] <tiwake> not really
[00:38:58] <tiwake> a little, but not really
[00:39:10] <Jymmm> solid vs liquid fuels
[00:39:25] <tiwake> since WW2?
[00:39:52] <tiwake> I mean there are hybrid engines these days... those are quite different in terms of fuel and how it works internally
[00:39:53] <Cromaglious> do they even have any thorium nuclear engines left? they have like .001 oz thrust but run for 100 years
[00:40:24] <Jymmm> hell, even rubber band propultion has changed, m'kay?!
[00:40:35] <tiwake> lol
[00:41:18] <Jymmm> Now, if you want to talk fire control (guidance systems), give me a moment....
[00:41:30] <tiwake> fuel/oxidizer pumps certainly changed with material and machining capabilities
[00:42:08] <tiwake> but none of that would change the launch site :)
[00:42:20] <Jymmm> tiwake: EXCELLENT video...
https://www.youtube.com/watch?v=s1i-dnAH9Y4
[00:43:44] <tiwake> "instantly solves these problems"
[00:44:29] <tiwake> hehe
[00:44:33] <tiwake> I want one of those computers
[00:44:46] <tiwake> that would be so fun to just have
[00:44:49] <Cromaglious> hmm I know there has to be a gcode to stop in the middle of a project and rezero the machine. any ideas
[00:44:57] <Jymmm> I'm just happy that I have a copy of the video =)
[00:48:14] <tiwake> Jymmm: this is strangely fun to watch
[00:48:50] <XXCoder> tiwake: old videos can be awesome
[00:48:55] <XXCoder> wish new ones is as good
[00:49:14] <tiwake> analog computing
[00:49:20] <XXCoder> wish someone would run those videos though new movement stabilizing rountine
[00:50:27] <tiwake> spyrograph
[00:53:54] <tiwake> oh gosh that part had to be expensive to make
[00:54:01] <tiwake> "barrel cam"
[00:58:28] <t12> zeeshan: gyro compass!
[00:58:31] <t12> that thing really moves
[00:58:47] <zeeshan> is there a motor stage below it?
[00:58:50] <zeeshan> thats moving it?
[00:59:03] <t12> nah its just floating on gimbals
[00:59:07] <zeeshan> ah
[00:59:08] <t12> the thing below it is the weird case they come in
[00:59:15] <t12> which is just easy to use as a stand
[00:59:26] <t12> usually they're all sealed up
[01:34:09] <Jymmm> tiwake: Not strange at all. applied math/physics in a very tangible and simplistic manner. Keep it simple stupid
[02:26:51] <Jymmm> hey Loetmichel
[02:28:55] <Jymmm> Loetmichel: I got one of these from 7-Eleven (a local chain of convenience stores open 24/7)
http://www.aironenow.com/vaporizer-starter-pack-premium-black/
[02:29:21] <Jymmm> err nation wide actually, not just local =)
[02:31:09] <XXCoder1> world-wise it is local lol
[02:31:15] <XXCoder1> no 7-11 outside usa so far I know
[03:01:08] <archivist> XXCoder1, world begs to differ
http://en.wikipedia.org/wiki/7-Eleven
[03:01:42] <XXCoder1> I stand corrected
[03:10:14] <Cromaglious> "
http://itslinux.org/cnc/Radiation Sign.tap"
[03:10:37] <XXCoder1> url isnt visitable. hexchat url dont support spaces apparently
[03:10:38] <Cromaglious> 1.5" radiation pendant
[03:10:50] <Cromaglious> "
http://itslinux.org/cnc/Radiation%20Sign.tap"
[03:11:01] <XXCoder1> already did it manually lol
[03:11:05] <archivist> and dont quote urls :)
[03:11:21] <XXCoder1> archivist: odd enough it knows enough to ignore "
[03:11:41] <Cromaglious> http://itslinux.org/cnc/Radiation%20Sign.tap
[03:12:14] <archivist> XXCoder1, I copied what was needed too :)
[03:12:20] <XXCoder1> so thats radation symbol
[03:12:42] <Cromaglious> except for the little hole for the necklace
[03:12:43] <XXCoder1> I just visited url, got 404 then added missing part to url
[03:12:50] <XXCoder1> dont even need to copy and paste
[03:13:28] <Jymmm> XXCoder1: what browser are you using?
[03:13:28] <Cromaglious> gonna cut that on Tuesday.. I forgot to add the center hole on the one I cut tonight
[03:13:34] <XXCoder1> firefox
[03:14:17] <Jymmm> ah, nm, I see what the issue was
[03:14:19] <archivist> best url of the day
https://www.youtube.com/watch?v=sFrVdoOhu1Q
[03:15:05] <XXCoder1> air bearing
[03:15:29] <XXCoder1> whatever thing it is, it sure spun a long while when he spin it
[03:16:27] <Cromaglious> http://itslinux.org/cnc/RadiationSign.tap
[03:24:28] <Deejay> moin
[03:24:36] <XXCoder1> hey
[03:24:43] <XXCoder1> 1 am. definitely morning heh
[03:24:53] <Deejay> 9am here ;)
[03:25:19] <Jymmm> archivist: Wow, new cnc porn =)
[03:25:43] <XXCoder1> What is guy making archivist
[03:25:50] <XXCoder1> some air bearing thingy he was holding?
[03:26:17] <Jymmm> a 1 micron cnc lathe/grinder
[03:26:47] <XXCoder1> dang
[03:27:02] <XXCoder1> .001 tol would be very rough compared to that
[03:28:11] <archivist> he mentioned other method of lapping, I did this on a piston and bore, not easy
[03:29:01] <XXCoder1> interesting, grinder on lathe
[03:29:13] <XXCoder1> I notice grinder tend to make VERY accurate parts
[03:31:45] <RifRaf> that lathe was awesome
[03:32:00] <Jymmm> Video downloaded =)
[03:32:23] <XXCoder1> wish autocaptions was better but I bet its awesome video
[03:32:38] <XXCoder1> very good teaching videos is worth more than gold
[03:32:50] <RifRaf> yep spent the last 40 hours watching them here :)
[03:33:08] <XXCoder1> Jymmm: using youtube center?
[03:33:20] <Jymmm> XXCoder1: He had a bit of a thick accent. Yep =)
[03:33:50] <XXCoder1> Jy, old videos tend to be very surpising good
[03:33:58] <XXCoder1> goverment ones expecially
[03:34:16] <XXCoder1> its almost normal caption quality other than weird wrong words for techinical words
[03:34:34] <Jymmm> XXCoder1: I don't trust bookmarks anymore, got burned too many times.
[03:34:50] <XXCoder1> bookmarks?
[03:35:12] <Jymmm> XXCoder1: where you bookmark urls (favorites)
[03:35:32] <XXCoder1> ahh yea thought it was direct reply to youtube center
[03:35:42] <XXCoder1> its addon that allow me to do stuff
[03:35:47] <XXCoder1> like no more ads and download
[03:35:57] <Jymmm> Well, that too. But I use google bookmarks for that.
[03:37:42] <Jymmm> Just be careful, it's case sensative
[03:38:49] <Jymmm> I DO like that he said he gets his shit cheap off ebay, even though in the background you see craploads of TE =)
[03:39:10] <XXCoder1> maybe he gets em cheap off ebay
[03:39:25] <Jymmm> ?¿
[03:39:38] <XXCoder1> TE heh
[03:41:02] <Jymmm> oh
[03:45:52] <archivist> I approve of cheap off fleabay
[03:48:22] <archivist> rubber hardness testing machine £1 same as
http://www.ebay.co.uk/itm/221358140353
[03:48:47] <archivist> mine was missing the two testing weights
[03:49:47] <XXCoder1> how do it work
[03:50:38] <archivist> it makes a small indentation, set 0, add second weight, measure amount deformed
[03:51:02] <XXCoder1> interesting
[03:51:22] <XXCoder1> I guess very hard metals need more weight
[03:51:37] <archivist> 20 years ago I needed one, but at that price it was worth fetching to play and learn
[03:52:05] <XXCoder1> 20 years ago I was 19 and still lost on what to do
[03:52:34] <archivist> I was the at the magic age of 42
[03:53:09] <XXCoder1> ah when it is the answer to life, universe, and everything
[03:53:23] <XXCoder1> I will be that age in less than 3 years lol
[03:59:00] <XXCoder1> ever read hitchhiker guide to universe?
[03:59:12] <alex_joni> that's the wrong question in here
[03:59:48] <alex_joni> it should be more like: how many times have you read..
[03:59:49] <alex_joni> :)
[03:59:52] <XXCoder1> lol
[04:00:03] <alex_joni> morning all
[04:00:16] <archivist> never read it :), but did see the TV series
[04:00:21] <Jymmm> 0.01 times
[04:00:23] <alex_joni> archivist: bugger that
[04:00:45] <archivist> I dont read fiction
[04:01:06] <alex_joni> it's only fiction for now..
[04:01:26] <Jymmm> archivist: You must not vote then =)
[04:06:27] <Jymmm> archivist: ... cause everything that comes out of their mouth is fiction

[04:11:44] <XXCoder1> focus, dammit
[04:12:06] <XXCoder1> some people dont know how to use camera
[04:12:13] <XXCoder1> cook nevertheless
[04:16:23] <XXCoder1> *cool
[04:26:19] <Cromaglious> durn it... sketchup + geargenerator + sketchUcam will not make a gcode for for the outside gear on a 21 tooth gear, it made one for the 13 tooth gear
[04:28:57] <Cromaglious> http://itslinux.org/cnc/gear13-21.skp
[04:29:32] <Cromaglious> http://itslinux.org/cnc/gear13-21.dxf is the source .dxf
[04:29:45] <XXCoder1> lemme try solevspace a sec
[04:30:02] <XXCoder1> not found
[04:30:15] <Cromaglious> oops lemme upload
[04:31:12] <Cromaglious> ok uploaded
[04:32:08] <Cromaglious> I had to clean up the dxf
[04:32:32] <Cromaglious> root radius are crappy on the gears
[04:32:56] <XXCoder1> cant import into solvespace
[04:33:33] <Cromaglious> it's a polyline dxf
[04:34:52] <XXCoder1> oh well
[04:36:55] <Cromaglious> http://itslinux.org/cnc/gear13-21basic.dxf
[04:37:47] <XXCoder1> solvespace is amazing but still too new sadly
[04:47:02] <XXCoder1> well night
[04:47:37] <Cromaglious> nite
[05:04:20] <Jymmm> https://www.fasttech.com/products/1005/10011738/2017504-dc-dc-10-32v-to-12-46v-car-laptop-power-supply
[05:10:45] <Cromaglious> that's pretty neat
[05:12:02] <Jymmm> cheap enough to have a higher DC voltage PS at hand if needed.
[05:37:04] <Cromaglious> they got a bunch of stuff on that site..
[05:41:55] <Cromaglious> Hmm thinking about putting some of these in the car

[09:04:16] <Swapper> anyone knows if its prohibitively expensive to get stuff laser/plasma cut ?
[09:04:31] <Swapper> plain sheetmetal 0.7mm
[09:05:41] <archivist> not that costly, mostly up against setup/minimum order
[09:06:38] <archivist> I have a local company and last time I went in the minimum order was £100
[09:07:27] <_methods> our minimum is $75
[09:08:05] <Swapper> _methods: and that would make it possible to get some parts cut in that price?
[09:08:19] <_methods> sure
[09:08:31] <_methods> especially if you have dxf/models
[09:08:39] <Swapper> im planning on cutting out some parts for a coolant tank and chip tray about 2 square meters of 0.7 sheetmetal
[09:08:48] <archivist> there is often a setup cost, read in your file, check it, load machine etc
[09:08:50] <Swapper> i have all in cad
[09:08:59] <_methods> you just want them cut?
[09:09:04] <Swapper> yea
[09:09:14] <_methods> .7 is thin
[09:09:17] <Swapper> i have sheet break and welder my self
[09:09:21] <_methods> k
[09:09:32] <Swapper> cant break more than that
[09:09:34] <_methods> yeah if you walk into any local shop with drawings
[09:09:35] <archivist> seems thin for the volume
[09:09:38] <_methods> they'll be happy
[09:09:56] <_methods> it's when you walk in with a napkin that it can get expensive
[09:09:57] <Swapper> i reccon it will be stiffer when i weld it up
[09:10:25] <Swapper> is a upgrade from a plastic container
[09:10:27] <Swapper> so...
[09:10:27] <archivist> its the wall bulging under the weight
[09:11:01] <archivist> we used to send in a dxf
[09:11:20] <_methods> if you go there with the material and the drawings in dxf format it will just be a time thing for them
[09:11:36] <_methods> you can get it done for probably around $100
[09:11:36] <Swapper> id like to get the mats from them
[09:11:47] <Swapper> that seems what i where thinking
[09:12:04] <_methods> yeah if it's steel that's dirt cheap anyways
[09:12:16] <_methods> a 5x10 sheet of that would probably be like $60
[09:12:22] <Swapper> yea plain un treeted sheet metal
[09:13:22] <_methods> how big are teh parts?
[09:13:53] <Swapper> the biggest is 600mm long and about 400mm wide
[09:14:13] <Swapper> think ill get it all in on a 2x1m sheet
[09:14:34] <Swapper> 0.7 is tig weldable right
[09:14:35] <Swapper> ?
[09:14:42] <Swapper> will it warp like crazy ?
[09:14:43] <_methods> yeah if you can tig
[09:15:07] <_methods> i wouldn't want to try and mig thin stuff like that
[09:15:17] <Swapper> nah only have tig
[09:15:51] <archivist> bit like gluing car body tin
[09:16:11] <_methods> yeah it should tig just fine and i'm sure a good welder could mig it
[09:16:24] <_methods> but i'd blow so many holes in it
[09:16:36] <_methods> i'm a hurrible welder
[09:16:55] <Swapper> atleast ill learn to tig better doin it :)
[09:17:06] <Swapper> as long as its not aluminum....
[09:17:07] <_methods> practice on coke cans hehe
[09:17:08] <Swapper> hate that
[09:17:47] <Swapper> stainless and normal sheet metal i have done some on and thats fine
[09:17:48] <archivist> rusty car tin sorts out the skilled from me
[09:18:07] <Swapper> stainless warps a lot and scales but that dosnt matter
[09:18:12] <_methods> yeah i tried to weld a rust muffler one time...........
[09:18:20] <_methods> i had to call my buddy who is a real welder lol
[09:18:50] <archivist> I am trained but on thick mig and stick
[09:18:52] <_methods> s/rust/rusty
[09:18:55] <Swapper> cleanlines is real differance when tig ing
[09:20:19] <Swapper> asked a local company and they take 64$ in "setup" for the laser
[09:20:29] <Swapper> + seconds / minutes per part
[09:20:31] <Swapper> in cutting time
[09:20:37] <Swapper> + materials
[09:21:00] <_methods> that sounds about right
[09:21:20] <_methods> we're pretty low at $75 min charge
[09:21:28] <_methods> most shops are $100+
[09:21:47] <Swapper> might get the parts for 200-250$
[09:21:49] <Swapper> humz
[09:22:13] <_methods> well with that thin of material you can lay it out and use tin snips
[09:22:24] <_methods> or a jig saw
[09:22:28] <Swapper> yea, i do have a plasma
[09:22:29] <archivist> or just get it cropped
[09:22:30] <Swapper> manual
[09:41:38] <ssi> morn
[09:43:10] <ssi> Swapper: plasma cuts thin steel like that pretty well
[09:43:29] <Swapper> yea its mostly the layoutwork and souch
[09:43:36] <ssi> just do what I did
[09:43:44] <ssi> build yourself a cnc table for your plasma cutter :D
[09:43:53] <Swapper> IF i had the space i would !
[09:44:08] <Swapper> it would be real nice
[09:44:27] <Swapper> but it seems dificult to do without the right plasma cutter type
[10:07:12] <ssi> _methods:
https://pbs.twimg.com/media/CAEjLTdUMAEM0RZ.jpg:large
[10:07:19] <ssi> that's where I'm at with the new laser design
[10:07:47] <Swapper> thats a lot of alu extrusion
[10:07:56] <ssi> yeah it's going to cost me a mint :(
[10:08:50] <Swapper> there are some nice belt in belt drives that would work good for that
[10:08:54] <Swapper> and a servo drive
[10:09:05] <ssi> belt in belt?
[10:10:23] <Swapper> https://www.youtube.com/watch?v=T9QU3YQe-Sc
[10:11:18] <ssi> ohh
[10:11:25] <ssi> I don't really need that though, since there's no cutting force
[10:11:29] <ssi> straight belt drive is fine
[10:11:45] <Swapper> quite low backlash is the advantage
[10:11:54] <Swapper> no belt stretch
[10:12:12] <ssi> timing belt doesn't really have significant issues with backlash or stretch though
[10:12:19] <Swapper> at high accel you might get flex at those distances?
[10:12:38] <Swapper> or my sens of scale might be off :)
[10:12:49] <Swapper> that table is maybe not as long as it looks
[10:12:53] <ssi> it's 10'
[10:12:53] <archivist> his belt is fraying
[10:18:57] <furrywolf> hey baby, want to come home and... fray my belt?
[10:48:01] <_methods> ssi: looking good
[10:48:14] <_methods> i know why those rollers in the middle won't work
[10:48:29] <_methods> i got to mess with some this weekend
[10:48:35] <ssi> oh?
[10:48:43] <_methods> they rock in the track
[10:48:51] <ssi> blah
[10:48:52] <_methods> there's a lot of play that way vs av
[10:48:56] <_methods> V
[10:49:08] <_methods> yeah
[10:49:43] <_methods> but i don't know if they had enough tension on them
[10:50:44] <ssi> that doesn't make me happy
[10:50:55] <_methods> no sorry i found out on friday
[10:50:58] <_methods> i forgot to tell you
[10:51:07] <furrywolf> I want to make a plasma table one of these days, but I'm going to use aircraft cable to move it, not belts.
[10:51:22] <_methods> or found out on saturday
[10:51:50] <_methods> i think if you added a couple more wheels it may fix it though
[10:51:57] <_methods> but then that adds to the bearing count
[10:52:07] <ssi> how many wheels did you use
[10:52:09] <_methods> or add a bearing that rides on the extrusion
[10:52:13] <ssi> bearings are cheap
[10:52:24] <_methods> the one i was messing with was using 4 wheels
[10:52:33] <_methods> like your current design
[10:52:48] <_methods> so i think if you add a bearing to stabilize
[10:52:51] <_methods> that would fix it
[10:53:19] <_methods> just add 1 on top and one on bottom to increase bearing surface
[10:53:34] <_methods> have it run on the flat of the extrusion
[10:54:16] <_methods> you could probably get away with block of uhmw also
[10:54:24] <ssi> that would be much easier
[10:54:26] <_methods> or something equally "slippery"
[10:54:37] <_methods> just something to keep it from rocking
[10:54:54] <ssi> adding a bearing perpendicular to the carriage plate is going to be a hassle
[10:54:58] <ssi> I assume that's what you mean
[10:55:00] <_methods> yeah
[10:55:35] <_methods> well i suggest you just make up a carriage and try it in the extrusion
[10:55:41] <_methods> just so you can see what i'm talkin about
[10:55:56] <ssi> yeah
[10:56:07] <ssi> that table is a LOT of money in extrusion
[10:56:10] <_methods> yeah
[10:56:10] <ssi> like $800 or so
[10:56:34] <_methods> that's why i just plan on doing mine out of tubing
[10:56:42] <_methods> i'm a cheap bastard
[10:56:46] <ssi> I thought about it
[10:56:50] <ssi> but tubing doesn't make it that much cheaper
[10:56:55] <ssi> and it's a lot more difficult to get it right
[10:56:55] <_methods> really?
[10:57:29] <ssi> I priced out 2x4" rect tube, 1/8" wall
[10:57:42] <ssi> 10' sticks are about $50 apiece
[10:57:54] <_methods> 10'?
[10:58:03] <_methods> normally they are 20'
[10:58:11] <ssi> yeah I know
[10:58:12] <_methods> are they charging you to cut them ?
[10:58:14] <ssi> I just quoted a lenght and qty
[10:58:15] <ssi> no
[10:58:29] <ssi> I could probably get it cheaper
[10:58:31] <_methods> yeah
[10:58:39] <_methods> i would think $50 for 20'
[10:58:43] <_methods> but i don't know
[10:58:48] <_methods> i'd have to get quotes
[10:59:07] <furrywolf> ssi: what're you building?
[10:59:16] <ssi> laser table
[10:59:32] <_methods> but i think the alum extrusion is perfect for laser
[10:59:37] <_methods> it's lighter weight
[10:59:43] <ssi> and easier to keep it square
[10:59:44] <_methods> and easier to work with
[10:59:46] <furrywolf> I think I'll stick with plasma.
[10:59:47] <_methods> yeah
[10:59:55] <furrywolf> I'll be using all angle iron, no fancy aluminum.
[11:00:06] <ssi> I built my plasma table out of 3/16" wall 2x4 steel
[11:00:42] <furrywolf> I could use box, but the scrapyard always has a much better selection of angle.
[11:02:13] <ssi> I haven't been able to find a good metal supplier in atlanta actually
[11:02:19] <ssi> I don't think anyone here makes anything
[11:02:29] <_methods> heheh
[11:02:40] <furrywolf> it's getting that way here too... there's only one place left to buy metal, the others closed.
[11:03:35] <_methods> hell no one wants to be around that damn atl traffic
[11:03:39] <_methods> i'd move the hell out too
[11:04:10] <ssi> if no one wanted to be here cause traffic, there wouldn't be anymore traffic! :D
[11:04:42] <furrywolf> my plan is to use angle or box pointy-side-up and gate wheels rolling on it, and move it around with aircraft cable. cheap, sturdy...
[11:05:02] <_methods> heheh
[11:05:08] <_methods> this is true
[11:07:17] <furrywolf> plasma is dirty and messy, and anything delicate will be destroyed...
[11:07:54] <_methods> hell traffic is so bad there you had to buy airplanes
[11:09:03] <ssi> I'm still trying to figure out a way to commute to work by air
[11:09:11] <_methods> cannon
[11:09:12] <_methods> lol
[11:09:45] <_methods> i was looking at making a gyrocopter
[11:09:58] <ssi> haha I would love to fly a gyrocopter
[11:10:06] <ssi> dan thinks I'm nuts for it, and he'll fly almost anything
[11:10:10] <_methods> hell yeah i'm suprised more people don't use them
[11:10:18] <_methods> are they that dangerous?
[11:10:26] <ssi> when I went down to fl to pick up that pitts on tuesday, this was there
[11:10:26] <ssi> https://pbs.twimg.com/media/B__IDpUWoAArLTz.jpg:large
[11:10:31] <ssi> yeah they're pretty damn dangerous
[11:10:34] <furrywolf> I've yet to see why they're better than a proper copter...
[11:10:44] <ssi> they're FAR cheaper
[11:10:57] <_methods> yeah money
[11:11:07] <_methods> short takeoff and land
[11:11:18] <ssi> haha last night he and I were driving up to kennesaw and there was a guy pulling a trailer with a gyro on it
[11:11:28] <furrywolf> why? a swashplate and some heim joints doesn't add much to the cost, and you already have a second prop anyway for a tail...
[11:11:29] <ssi> and we pulled up next to him and dan rolls down the window and yelss "HEY! NICE DEATHTRAP"
[11:11:47] <_methods> damn i had no idea that they were that dangerous
[11:12:07] <ssi> I don't think they're as bad as he makes them sound
[11:12:13] <_methods> i guess that is a lot of spinning shit right next to your unprotected body
[11:12:27] <ssi> honestly I've seen a lot of gyroplane wreck videos
[11:12:31] <ssi> and people tend to walk away from them
[11:12:33] <ssi> but they LOOK nasty
[11:12:55] <_methods> yeah i thought the great thinga bout them was that if the engine crapped out on you you just autorotated down
[11:13:00] <ssi> you do
[11:13:03] * furrywolf doesn't see why a helicopter involves significantly more money than a gyrocopter
[11:13:07] <_methods> since they're basically in an autorotating state already
[11:13:08] <ssi> furrywolf: go build one
[11:13:52] <furrywolf> I have an r/c one, does that count? :P
[11:14:08] <ssi> _methods: if you're not gentle on them in pitch, you can stall the rotor, and even stall it so bad that it goes negative and flops into the prop
[11:14:14] <furrywolf> (and a real one. made of aluminum, with an engine. none of this plastic and batteries stuff...)
[11:14:15] <ssi> that's a Bad Day
[11:14:44] <ssi> furrywolf: well I dunno about you, but I have a "real one" too, and mine cost as much to build as a gyroplane that you can put your ass in :)
[11:15:12] <furrywolf> you spent real money on r/c stuff? heh
[11:15:57] <ssi> you should go build yourself a homebuilt helicopter
[11:16:01] <ssi> subaru powered
[11:16:09] <ssi> and report back on the costs
[11:16:12] <furrywolf> lol, I've seen that done.
[11:16:16] <furrywolf> it had an EJ22
[11:16:18] <ssi> oh I'm sure
[11:16:27] <archivist> death wish 9
[11:16:27] <ssi> honestly I'd much rather have a subie in a helicopter than an airplane
[11:16:31] <ssi> it couples much better
[11:16:44] <ssi> helicopters need a drive train either way
[11:17:14] <furrywolf> hrmm, what's a good rpm for a heli rotor?
[11:17:21] <ssi> depends on the diameter
[11:17:27] <ssi> robinsons run around 200rpm I think
[11:17:45] <furrywolf> that's a lot of reduction.
[11:17:47] <ssi> I don't know a ton about rotor aerodynamics, but at first blush I'd guess you want an rpm to maintain something like mach .85-.90 at the tips
[11:18:59] <furrywolf> google suggests 450rpm is common on a light helicopter. (from two search results)
[11:19:15] <furrywolf> so figure you need 10:1..
[11:19:23] <ssi> you need a governor too
[11:19:39] <jdh> like wisconsin?
[11:19:57] <ssi> shoot for something like 650fps tip speed
[11:20:29] <furrywolf> so strip everything but 2nd gear out of a subaru transaxle, pin it in 2nd, rotate the bellhousing 90 degrees, replace the diff with a spool, and presto, you have 10:1 AND a shaft pointing upwards. :)
[11:20:46] <ssi> what's that all gonna weigh
[11:20:57] <furrywolf> dunno. :P
[11:21:23] <ssi> remember you probably want this whole aircraft to weigh somewhere around 700lb
[11:21:57] <furrywolf> I bet you can use the stock cruise control actuator as a governor, too - it gets its input signal from the tranny...
[11:22:18] <furrywolf> just get the rpm where you want it and hit cruise. :)
[11:22:59] <furrywolf> heh, and the 4x4 transaxle even has another shaft sticking out the back to run your tail rotor off...
[11:23:20] <skunkworks> isn't there big discussion about using automotive engines in airplanes? Like - you will probably crash.
[11:23:33] <ssi> skunkworks: yeah this is just a continuation of that discussion
[11:23:35] <furrywolf> 700lbs seems awfully light. not planning on anything that light, ever...
[11:23:37] <ssi> furry's flat set on it
[11:23:42] <skunkworks> ah
[11:23:53] <ssi> furrywolf: if you think that sounds light you have zero business trying to build aircraft :D
[11:23:56] <furrywolf> no, I'm not flat set on it. you just suggested it, so now I'm see how it'd work. :P
[11:24:25] <furrywolf> ssi: what can I say, I'm used to building things big and heavy. I've built bumpers that weigh more than an ultralight. :P
[11:24:29] <ssi> it takes power to carry weight; it takes fuel to make power; it takes power to carry fuel
[11:24:33] <ssi> rinse repeat
[11:24:42] <ssi> it's not quite as nefarious as tsoliovsky's rocket equation, but it's close
[11:25:01] <ssi> and it's worse in a heli, because the rotor has to carry the load directly
[11:25:25] <furrywolf> helis need a clutch to start, right? you'd even get that included.
[11:25:25] <JT-Shop> yep everything is a balancing act
[11:25:26] <ssi> I was just looking at the safari... chances are good you're not gonna be able to build anything bigger than a safari
[11:25:31] <ssi> it's 1000lb empty, 1650lb gross
[11:25:41] <ssi> has a 26'4" rotor disc
[11:25:46] <skunkworks> When I was a kid I wanted to build an altralight.. I am glad I didn't.
[11:25:57] <ssi> uses a lycoming 180
[11:26:05] <ssi> makes 180hp and close to 400lbft torque
[11:26:11] <ssi> so use those as starting "sanity" numbers
[11:26:20] <ssi> if you can't get close to that with your napkin design, it's probably not going to work out
[11:26:52] <furrywolf> 180hp isn't hard, but it's probably heavier.
[11:27:11] <ssi> the lyco only weighs 250lb
[11:28:03] <ssi> also for reference
[11:28:07] <ssi> a safari kit costs $74,400
[11:28:26] <ssi> and that's everything you need except an engine and avionics
[11:28:40] <furrywolf> 180lbs is about what an EJ22T weighs.
[11:28:43] <furrywolf> 280
[11:28:45] <furrywolf> 250
[11:28:46] <furrywolf> bleh
[11:28:50] <ssi> JT-Shop: what do you estimate your bensen would cost to build?
[11:29:34] <furrywolf> ej22 long block is 188lbs, with turbo and stuff probably about 250.
[11:31:29] <furrywolf> someone weighed one at a little under 250lbs. so the engine is actually not heavier. I'm surprised.
[11:34:18] <jthornton> ssi, I never did figure a cost on it...
[11:38:16] <furrywolf> bbl, time for work
[11:38:59] <jthornton> there's not a whole lot to the machine so I guess it depends on if you try and find a McCulloch drone motor or use the VW 1600cc motor
[11:40:07] <furrywolf> wow, the subaru sti motor has an impressive power/weight.
[11:40:07] <furrywolf> bbl.
[11:40:39] <Loetmichel> Jymmm: looks nice for a starter pack
[11:41:01] <Jymmm> Loetmichel: It hits pretty well too.
[11:43:14] <jthornton> looks like every possible option plans are in the box
[11:43:31] <Jymmm> Loetmichel: I have some VG on it's way; going to "thin out" the juice I have a bit.
[12:07:45] <zeeshan> fak
[12:07:47] <zeeshan> the lathe sold
[12:07:47] <zeeshan> :[
[12:11:57] <pcw_home> Did you see that home made precision lathe on the Linuxcnc users list? That was pretty impressive (even if it was not running linuxcnc)
[12:12:30] <archivist> I wonder what the control is based on though
[12:12:36] <zeeshan> no i didnt
[12:12:47] <zeeshan> man i cant believe i missed this slant bed lathe
[12:12:48] <zeeshan> !!!
[12:12:52] <pcw_home> https://www.youtube.com/watch?v=sFrVdoOhu1Q
[12:12:53] <zeeshan> 2 days and its sold
[12:13:01] <zeeshan> oh this one
[12:13:05] <zeeshan> dan gelbart -- the genious
[12:13:41] <zeeshan> those buttons look very windows like
[12:13:53] <pcw_home> all air bearing
[12:13:55] <zeeshan> pcw_home: did you see my q?
[12:14:01] <pcw_home> no
[12:14:19] <zeeshan> about why you said backlash with a stepper-glass scale position control through linuxcnc
[12:14:21] <zeeshan> is not good?
[12:16:01] <pcw_home> Yeah its not (well if the forces are unidirectional its not so bad like using a manual machine)
[12:16:05] <zeeshan> https://www.youtube.com/watch?v=ccjTMQwKWNs
[12:16:18] <zeeshan> his steam engine, last ~2 min are best. crazy valve design
[12:16:21] <zeeshan> (electrical part of it)
[12:16:41] <zeeshan> pcw_home: why is backlash okay on a servo-glass machine?
[12:16:47] <zeeshan> i'm trying to understand the difference
[12:17:02] <pcw_home> backlash is never good
[12:17:30] <zeeshan> lets say youre commanding 1" (reversal) and with backlash you hit .996"
[12:17:48] <zeeshan> wouldnt the position control be like 'there is an error of .004' -- i need to move the stepper another 0.004"
[12:18:19] <zeeshan> and continue to do that indefinitely?
[12:18:27] <pcw_home> right, now you want the servo to instantly step .004
[12:18:28] <zeeshan> eveyrtime there is a reversal
[12:18:53] <pcw_home> = big quadrant glitches
[12:20:49] <zeeshan> so when it tries to step 0.004" it'll overshoot?
[12:21:59] <pcw_home> well lots of bad things happen (one is inertial load is lower during backlash move)
[12:22:14] <pcw_home> so tuning is different
[12:25:49] <pcw_home> plus backlash simple makes it very difficult to tune
[12:25:51] <pcw_home> I suppose in the stepgen case and with dual (rotary and linear) encoders
[12:25:52] <pcw_home> you could have some very smart controller but the root of the problems is
[12:25:54] <pcw_home> you now have a relatively long response time to external forces of unknown direction
[12:26:41] <jdh> my router with lash digs in when reversing one way
[12:27:16] <pcw_home> yeah this is all without even worrying about tool issues
[12:27:28] <zeeshan> digs in?
[12:28:01] <archivist> climbing, a way to break tools
[12:29:09] <jdh> while it is moving enough to take out the lash, the bit bounces a little then digs in to the materual
[12:29:15] <zeeshan> ah
[12:29:37] <zeeshan> i was wondering if control could compensate for that :P
[12:30:01] <pcw_home> I suspect the tool can be pulled into the work faster than the servo can react and take up the backlash
[12:30:26] <jdh> fix mechamical problems with mechanics, not software
[12:30:50] <zeeshan> jdh: ofcourse :) this was a purely theoretical question
[12:30:55] <zeeshan> on why its not good for the control system
[12:33:24] <pcw_home> I the general case imagine how a system with backlash responds with random disturb inputs
[12:33:54] <zeeshan> i can imagine an oscillation
[12:34:33] <zeeshan> tool commands 0.004" movement, tool moves to error free position, the load builds up again causing backlash, and the cycle repeats
[12:34:56] <zeeshan> with a phase shift delay in response
[12:35:04] <pcw_home> Yes, with dual feedback you can eliminate most oscillation but the stiffness at important frequencies is poor
[12:37:10] <pcw_home> now if you have a lot of linear axis mass and small cutting forces backlash is more manageable
[12:37:42] <pcw_home> but thats is not a good machine design
[12:38:37] <pcw_home> (very mis-matched rotary/linear inertia is not good)
[12:39:16] <zeeshan> best is to eliminate it :)
[13:52:01] <ssi> zeeshan: what lathe
[13:52:26] <zeeshan> http://i.ebayimg.com/00/s/NjAwWDgwMA==/z/zc8AAOSweW5VAzPC/$_35.JPG
[13:52:29] <zeeshan> that thing
[13:52:40] <ssi> aha
[13:52:47] <zeeshan> was going for 2k
[13:52:50] <zeeshan> slant bed, tool changer etc
[13:52:54] <zeeshan> =/
[13:53:01] <XXCoder1> was it sold?
[13:53:11] <zeeshan> yea it got sold by the time i called
[13:53:15] <XXCoder1> drat
[13:53:23] <zeeshan> prolly a good thing
[13:53:26] <zeeshan> it has fanuc controls :p
[13:53:35] <zeeshan> which after ssi's experience looks like a pain in the ass to retrofit
[13:54:02] <ssi> eh
[13:56:39] <ssi> I'm fighting with solidworks
[13:56:44] <ssi> it can be a pain in the ass for certain things
[13:56:54] <zeeshan> like what
[13:57:35] <ssi> I'm trying to model a wing truss rib
[13:57:45] <ssi> so I started with a coordinate plot of a NACA 0012
[13:57:51] <ssi> imported it as a curve
[13:58:04] <ssi> then I had to scale that curve to the chord length, cause as imported it's 1" long
[13:58:13] <ssi> now I'm trying to use that as reference geometry for everything else
[13:58:35] <ssi> but annoying stuff like, I need to offset that curve by 1/16" inward to account for leading edge thickness and rib capstrip
[13:58:38] <ssi> and it won't do that reliably
[13:58:57] <ssi> like... if I cut the trailing edge off so that there's room for the new offset path to come to a sharp point, it will do it
[13:59:02] <ssi> but it's behaving oddly and annoyingly
[14:00:44] <ssi> so for instance... I start with the bare sketch of the scaled up curve
[14:01:04] <ssi> I drop a vertical construction line that is coincident with the top and bottom of the curve, and dimension it so that it's 0.15" tall
[14:01:11] <ssi> which positions it some distance from the trailing edge
[14:01:18] <ssi> then I use trim to cut off the trailing edge
[14:01:25] <ssi> then I do an offset entities inward by 0.0625"
[14:01:29] <ssi> and it draws it but says it's unsolvable
[14:01:31] <ssi> and I can't figure out why
[14:01:46] <zeeshan> is it a bunch of points?
[14:01:49] <zeeshan> screenshot? :D
[14:02:06] <ssi> hm
[14:02:06] <ssi> ok
[14:02:07] <ssi> sec
[14:03:23] <ssi> this is gonna be a step by step photojournal
[14:03:27] <ssi> it'll take a few
[14:03:35] <ssi> https://pbs.twimg.com/media/CAPV4pBXEAEEVy7.jpg:large
[14:03:41] <ssi> creating the curve from a coordinate file
[14:03:45] <ssi> https://pbs.twimg.com/media/CAPV8mEWAAI4IU3.jpg:large
[14:03:47] <ssi> the resultant curve
[14:05:05] <ssi> not I can't remember how I did the scale
[14:05:58] <ssi> https://pbs.twimg.com/media/CAPWiB2WMAEERDf.jpg:large
[14:06:00] <ssi> but there's the scaled curve
[14:06:11] <ssi> so now that's the dimension that I want to hold my finished product to
[14:06:37] <ssi> I need a reference line that's 1/16" smaller than that, so I'm going to try to do offset entities from that
[14:06:52] <zeeshan> the curve self interesects
[14:06:54] <zeeshan> in that image
[14:06:55] <ssi> as is, it'll let me go OUT, but not IN
[14:07:07] <zeeshan> on the left
[14:07:07] <ssi> you're seeing two different curves
[14:07:11] <zeeshan> oh
[14:07:13] <zeeshan> hahaha
[14:07:16] <zeeshan> thats a huge scale jump
[14:07:21] <ssi> the big one is a scaled spline from the small one
[14:07:34] <ssi> yes, cause the airfoil coordinates are scaled from 0 to 1 in units of chord
[14:07:41] <ssi> and it imports as 0 to 1 in units of inches
[14:07:46] <ssi> but I need a 36" chord
[14:07:49] <ssi> so I scale the spline by 36
[14:08:02] <ssi> I guess I could scale the coordinate file
[14:08:08] <ssi> but that's not really the issue
[14:08:11] <zeeshan> when you click on the curve
[14:08:18] <zeeshan> is it a bunch of points?
[14:08:25] <ssi> no it's a single spline
[14:08:27] <zeeshan> ok
[14:08:41] <ssi> it's actually a "curve" entity
[14:08:57] <ssi> Insert > Curve > Curve through XYZ points
[14:09:03] <ssi> give it a text file full of points and it creates the curve
[14:09:21] <ssi> wonder if you could open the part file
[14:09:37] <ssi> do you use dropbox?
[14:09:47] <ssi> I keep all my solidworks crap in dropbox, I could just share you the folder
[14:09:54] <zeeshan> yews
[14:14:16] <zeeshan> i see the problem
[14:14:26] <zeeshan> zoom in to the very right
[14:14:53] <ssi> yeah...
[14:15:04] <ssi> talking about the "knuckle" in the trailing edge?
[14:15:31] <ssi> maybe I should scale up the raw coordinates and see if it renders better
[14:15:38] <zeeshan> http://i.imgur.com/lDc7tDr.png
[14:15:49] <zeeshan> if you try to offset more than 0.02"
[14:15:59] <ssi> yeah
[14:16:02] <zeeshan> that radius wont hold anymore
[14:16:04] <ssi> that's why I've been cutting off the trailing edge
[14:16:05] <zeeshan> youre limited by that radius
[14:16:13] <ssi> I don't want a radius, I want a sharp trailing edge
[14:16:53] <Jymmm> Is it common for an SSD to draw 1.5A ?
[14:17:27] <renesis> thats seems like a lot but not totally unreasonable, its low voltage
[14:17:30] <ssi> lemme see if I can manually massage the coordinates
[14:17:49] <renesis> jymmm: is that measured or spec?
[14:18:02] <Jymmm> renesis: 5VDC @ 1.6A (rated)
[14:18:12] <renesis> yeah thats like 7W
[14:18:32] <ssi> zeeshan: I think solidworks is truncating the resolution of the original input coords
[14:18:33] <renesis> it prob doesnt use that all the time
[14:18:36] <ssi> I just need to scale them in text
[14:18:44] <Jymmm> renesis: Bummer, won't work in my external usb enclosure
[14:18:49] <Jymmm> renesis: thanks
[14:18:58] <renesis> np
[14:19:19] <Jymmm> renesis: 128GB Sandisk half-slim $25
[14:19:20] <zeeshan> lemme try somethin
[14:19:21] <renesis> jymmm: you already have the ssd?
[14:19:31] <Jymmm> renesis: In about an hour =)
[14:19:36] <renesis> nice
[14:19:49] <Jymmm> renesis: Surplus store
[14:19:53] <renesis> they prob have some lower power ones, i doubt theyll be cheap as that tho
[14:20:05] <renesis> electronics surplus?
[14:20:10] <zeeshan> i can hack it up
[14:20:12] <zeeshan> if you want
[14:20:14] <zeeshan> and make it work
[14:20:14] <zeeshan> lol
[14:20:25] <Jymmm> renesis: Yeah, I can try and use it in my netbook instead
[14:21:10] <renesis> wonder if the ssd in my eee4g is toast
[14:21:19] <renesis> its soldered onto the board =\
[14:21:30] <Jymmm> http://www.sandisk.com/products/ssd/sata/x110/
[14:21:43] <renesis> one of the rubber dome springs on the keyboard broke off, gotta get new one
[14:21:56] <Jymmm> renesis: ebay
[14:22:10] <renesis> Active Power (Typical): 120mW (@ 3.3V)
[14:22:11] <Jymmm> just replace the whole dman kybd =)
[14:22:17] <renesis> yeah thats the plan
[14:22:27] <renesis> but its low priority because its kind of just a neat toy
[14:22:33] <Jymmm> ah
[14:22:47] <renesis> 800x480 display
[14:23:01] <renesis> its literally the first netbook
[14:23:22] <renesis> and the ssd is only 4gb so getting xp on it is drama
[14:23:26] <XXCoder1> aspire one eh
[14:23:27] <Jymmm> I like the netbook cause I have a usb gps wifi, 10" screen and a real uart serial port via EC34 clot
[14:23:31] <renesis> it shipped with linux
[14:23:35] <XXCoder1> ssd yeah I own one, I love it
[14:23:43] <renesis> xxcoder1: asus eee
[14:23:49] <XXCoder1> ah yeah that one
[14:24:03] <Jymmm> Mines a ThinkPad S10 (original, 1st gen)
[14:24:05] <XXCoder1> I decided to go for aspire one, better design
[14:24:12] <renesis> like, within 6 months they released something that was literally scaled up 10%
[14:24:23] <renesis> with a 1024x600 display
[14:24:31] <XXCoder1> well gonna run laters
[14:24:38] <renesis> laters
[14:24:39] <zeeshan> ssi
[14:24:39] <zeeshan> wtf
[14:24:45] <zeeshan> give me upload permission
[14:24:55] <renesis> jymmm: thats an idea pad branded thing?
[14:25:01] <ssi> zeeshan: hm sec
[14:25:06] <zeeshan> actually dont
[14:25:07] <zeeshan> here
[14:25:08] <zeeshan> https://www.dropbox.com/s/b8x8lt4wyzawwpi/Full%20Truss%20Rib_v1.SLDPRT?dl=0
[14:25:13] <zeeshan> thats my work around to that curve nonsense
[14:25:14] <renesis> i think thats what i told my english teacher to get
[14:25:19] <Jymmm> renesis: Lenovo
[14:25:30] <renesis> right but its thinkpad or ideapad?
[14:25:56] <renesis> she got one of their first netbooks but it wasnt thinkpad branded, i forgot the model
[14:26:02] <ssi> zeeshan: what did you do exactly?
[14:26:09] <renesis> but she still uses, she got it prob 5 years ago, maybe longer
[14:26:19] <Jymmm> ah yeah, used to thinkpad, it's IdeaPad =)
[14:26:31] <Jymmm> lenovo S10-1 =)
[14:26:47] <renesis> yeah she dropped it and one of the hinge endcaps popped off
[14:27:05] <zeeshan> ssi use spline tool
[14:27:05] <renesis> years and years ago, besides that i think its been fine
[14:27:14] <zeeshan> start at the intiial point on the left
[14:27:18] <renesis> she uses it in class to push youtube videos to the projector
[14:27:27] <zeeshan> click on the curve a bunch of times especially where it changes radius of curvuture
[14:27:43] <zeeshan> end the spline, then make a line tangent to spline at the right side
[14:28:03] <ssi> k
[14:28:05] <zeeshan> mirror
[14:28:10] <ssi> lemme finish scaling up this naca file and see what it does
[14:28:14] <Jymmm> renesis: faster is nice and all, but I'm hoping it'll save battery life mostly
[14:28:21] <ssi> can't assume mirror, this is a symmetrical foil but most aren't
[14:28:29] <zeeshan> oh
[14:28:45] <zeeshan> thats true you want the top side
[14:28:48] <zeeshan> to be longer than bottom yea?
[14:28:50] <renesis> jymmm: yeah if replacing platter drive it should
[14:28:56] <renesis> its not gonna pull 7W all the time
[14:28:59] <ssi> depends
[14:29:24] <renesis> the link you gave for the product family says 120mW typical
[14:29:33] <Jymmm> renesis: I just con't know how much of a savings
[14:29:43] <renesis> gotta test!
[14:30:22] <Jymmm> yeah, I know. I COULD just read the spec for the hdd in it too =)
[14:30:28] <renesis> would do quick benchmark before swapping
[14:30:54] <zeeshan> lol im looking at one my assignments the prof marked
[14:30:56] <renesis> like, play movie and file copy after reboot, at the end check battery
[14:30:56] <zeeshan> i wrote kW
[14:30:58] <Jymmm> permoane wise?
[14:31:02] <zeeshan> but it looks like kw
[14:31:06] <Jymmm> performance wise?
[14:31:09] <zeeshan> he wrote a big note saying K is kelvin
[14:31:12] <zeeshan> k is kilo
[14:31:13] <zeeshan> lol
[14:31:16] <renesis> jymmm: battery
[14:31:22] <zeeshan> jeez!
[14:31:24] <Jymmm> renesis: ah
[14:31:43] <renesis> nothing to rigurous, just something you can repeat
[14:32:03] <renesis> tho you prob have to reinstall system so not great comparison unless you reinstall before swapping, too
[14:32:08] <renesis> which is drama
[14:32:36] <Jymmm> I was going to image the HDD to SSD
[14:32:44] <renesis> but itll give you an idea, itll likely look like better power savings than it actually is
[14:32:54] <renesis> yeah that might work
[14:33:17] <Jymmm> do you need wear leveling stuff instaled?
[14:33:23] <renesis> its built in
[14:33:47] <Jymmm> then why do I always see wear utilit/drivers and shit?
[14:33:53] <renesis> the hardware deals with it, its pretty transparent to the OS, besides checking SMART stuff
[14:34:13] <renesis> because people need to sell software, shrug
[14:34:21] <Jymmm> Yeahs, alwasy seemed dumb to me to have sdd utility/drivers
[14:34:25] <Jymmm> lol
[14:34:38] <renesis> ssd shouldnt need specific drivers
[14:34:45] <renesis> like, manufacturer/model specific
[14:34:49] <Jymmm> sata be sata damnit
[14:35:08] <renesis> right, all the wear leveling is handled in the drive firmware
[14:35:31] <Jymmm> I wonder where they pulled them from, they have 100+ in stock
[14:36:04] <renesis> sounds like initial production fuckup quantity
[14:36:11] <renesis> if they were in an electronics surplus shop
[14:36:53] <Jymmm> Not sure, U'll have to see how they are packaged if at all
[14:37:02] <renesis> not production of the ssd, like someone sourced them for a project and it didnt work
[14:37:49] <renesis> i dont think a computer shop going out of business explains 100+ for one model
[14:37:53] <Jymmm> yeah, I get it. I just hope it's not pulls.
[14:38:08] <renesis> did they look the same?
[14:38:16] <renesis> packaging
[14:38:44] <renesis> if the shit doesnt look all random and handled, would be less worried
[14:38:46] <Jymmm> I dont know, I shop their website first to see whats new, then spend hours in the isle as they dont list everything on the wbesite
[14:38:53] <renesis> oh its a website
[14:39:04] * JT-Shop tries to decide if I want to change bicycle tires or continue welding
[14:39:26] <Jymmm> IT's electronic compontent surplus, but if they have large qty of items, they toss them on the website too.
[14:39:27] <renesis> do you have those tire lever things?
[14:39:39] <renesis> if you dont have those little tire lever things, i would put it off
[14:39:53] <JT-Shop> yea, but you don't need them for a mountain bike tires
[14:40:17] <renesis> you dont, but omg its so much faster, easier, nice to the wheels
[14:40:39] <JT-Shop> you just pull the tire off, no tools needed
[14:40:57] <renesis> mountainbike is that loose?
[14:41:04] <JT-Shop> road bike may be different I don't know
[14:41:11] <JT-Shop> yea, they just fall off
[14:41:14] <renesis> i ride 24" bmx, i assumed 26" would be pretty much same
[14:41:19] <renesis> haha cool
[14:41:25] <JT-Shop> mine is a 29"
[14:41:30] <renesis> yeah i dont ride road bikes, i dont like the larger frames
[14:41:31] <renesis> oh
[14:41:39] <renesis> yeah i bet thats easy
[14:42:04] <JT-Shop> well I do have a 26" too but need to sell it
[14:42:28] * JT-Shop fell off a bmx once... backwards
[14:42:40] <renesis> but yeah road bike is almost same as what i ride (before stolen) except you cant wobble it and get youre arms into it
[14:42:59] <JT-Shop> last time I tried to do a wheelie
[14:43:10] <renesis> yeah i dont do tricks =\
[14:43:26] <ssi> zeeshan: open the new document in my dropbox called Rib Sketch Full Size
[14:43:40] <renesis> i just like the 24" race bikes, because theyre light and small and can get the cranks long
[14:43:51] <jdh> I have a pair of nice new tires to put on tonight!
[14:43:51] <ssi> I scaled it up to 36" in the coordinates file, imported the curve, it still has a TE radius, but I cut it off and just extended it tangent to the curve at the back and that looks pretty good
[14:44:31] <renesis> but the fact that you can lean a low profile bmx frame like 45 degrees while pedaling is huge
[14:45:07] <zeeshan> nice
[14:45:09] <zeeshan> looks good
[14:45:10] <renesis> you can basically use your arms to pull the bike up into your foot, is almost like an eliptical motion
[14:45:45] <ssi> I'm going to create the truss with weldments :P
[14:45:54] <renesis> cant even really do that on the smaller road/track bikes
[14:47:24] <renesis> heh, pretty much everyone has brakes and freewheel hubs on their hipster bikes
[14:48:00] <jdh> hipsters have no brake fixies
[14:48:08] <renesis> they mostly gave up
[14:48:33] <renesis> they have the fixie velodrome racers, but with brakes and freewheels
[14:48:47] <renesis> fuckin idiots cant stop
[14:48:55] <JT-Shop> ssi, what are you building now?
[14:49:11] <jdh> I have two Ti and one crabon road bikes now
[14:49:27] <renesis> fixies or sane bikes?
[14:49:29] <ssi> JT-Shop: I want to come up with really nice cad models of the pitts wings, so when I get the new laser running I can do laser cut wing kits
[14:51:20] <jdh> road bikes have gears and brakes
[14:51:55] <renesis> right see i know people who call single speed bike road bikes
[14:52:20] <renesis> like, same type of frame, brakes and freewheel hubs, just no gears
[14:52:22] <renesis> shrug
[14:52:40] <jdh> whatever works for them
[14:53:04] <renesis> want another 24" bmw with 180mm cranks and stupid long gearing
[14:54:03] <JT-Shop> cool
[14:54:10] <renesis> haha, someone was going to give me a beach cruiser, had coaster brakes and like, 165mm cranks or something
[14:54:18] <renesis> that shit was so scary
[14:55:20] <renesis> couldnt really stop, def couldnt get it moving quick, so high turning felt all slow and stupid
[14:55:36] <renesis> slow heavy bikes are dangerous
[14:56:58] <ssi> aw man, solidworks won't let me do a weldment on a curve?
[14:57:33] <_methods> only lines and arcs i think
[14:58:47] <ssi> I'll have to do it with a loft
[14:59:26] <_methods> what are you lofting? your wing profile?
[14:59:56] <ssi> nah, just the truss sticks
[14:59:59] <ssi> I'll show you in a few
[15:10:52] <JT-Shop> dang nice looking tires
[15:16:06] <_methods> http://www.affordaplane.com/
[15:16:18] <_methods> you don't have to worry about farts in that plane cabin
[15:16:41] <jdh> what tires?
[15:17:08] <ssi> bit too flimsy for my taste
[15:19:27] <_methods> you can buy one at ikea now hehe
[15:21:40] <ssi> heheh
[15:21:44] <ssi> you see the flatpack gokart?
[15:21:52] <ssi> http://www.gizmag.com/flatpack-go-kart-fly-ply-25-mph/36556/
[15:28:06] <_methods> oh damn that's brilliant
[15:28:18] <_methods> until your kid leaves it out in the rain lol
[15:28:22] <_methods> or you hit a mud puddle
[15:28:51] <Cromaglious_> mmmmm Ikea meatball Lunch
[15:29:16] <Cromaglious_> nice cool 94F in San Diego
[15:30:00] <_methods> termites ate my go kart
[15:30:12] <Cromaglious_> Ok, so we're on the I-15, it was cooler closer to the water
[15:30:14] <ssi> :D
[15:30:29] <renesis> meduza: left it out in the rain, now it needs strut towers
[15:30:33] <renesis> er
[15:30:35] <renesis> _methods: ^
[15:30:42] <_methods> hehe
[15:30:49] <renesis> oh, you said that already
[15:31:51] <Cromaglious_> well my Caddi either needs plugs, which got changed 20K ago or I need to repace the starter which is in the valley under the intake manifold
[15:32:22] <Cromaglious_> s/repace/replace
[15:33:36] <Cromaglious_> Escondido, 95f
[15:34:00] <_methods> yeah it's 80f today
[15:34:04] <_methods> lovin it
[15:34:10] <Cromaglious_> hehe 95f on one side of the hill and 91F on the other
[15:34:22] <_methods> ah man that's great
[15:34:29] <_methods> i'm happy with 80 though
[15:34:38] <_methods> better than freezin to death at 70 lol
[15:34:45] <Cromaglious_> gotta love marine layer
[15:35:10] <_methods> i started lookin at diy airplanes
[15:35:27] <_methods> now he got me all sidetracked on go karts
[15:35:30] <Cromaglious_> CX100 composite BD-5
[15:35:53] <_methods> my brain is sayin plane but my wallet is lookin go kart
[15:36:00] <_methods> hahah
[15:36:05] <Cromaglious_> NACA 2520 wing foil same as wing root of DC3, wing that doesn't know how to stall
[15:36:42] <ssi> _methods: :)
[15:37:02] <_methods> omg but the search led me to this krazee gem of a site
[15:37:06] <_methods> http://ubuilditplans.com/
[15:37:10] <Cromaglious_> I'm thinking getting a electric wheel for my felt 90
[15:37:12] <_methods> diy backhoe
[15:37:21] <ssi> _methods: I kinda want a powered paraglider
[15:37:36] <_methods> diy bulldozer
[15:37:40] <_methods> GTFO
[15:38:01] <_methods> http://ubuilditplans.com/BMDDozer.html
[15:38:06] <_methods> that is hilarious
[15:38:20] <Cromaglious_> _methods: those work really good!
[15:38:38] <_methods> i would have never thought to make my own dozer hehe
[15:38:52] <_methods> wait till my HOA get's a load of this
[15:39:18] <Cromaglious_> HOA's are evil! Pure Evil!
[15:39:22] <_methods> hehe
[15:40:35] <Cromaglious_> bean counters can become Prident and turn their HOA into little Naziland
[15:40:42] <Cromaglious_> president
[15:43:07] <ssi> gah sw is really really not working with me here
[15:45:11] <Cromaglious_> sw ? software, or Southwest Airlines
[15:45:16] <ssi> solidworks
[15:47:31] <Cromaglious_> can't afford it, don't have it, that's why I've been fighting Sketchup, Gear Generator, SketchUcam
[15:50:05] <Cromaglious_> though on SketchUcation I foud a gear generator that letting me produce gcode using sketchUcam, only thing it is make gears with depth,,,
[15:52:12] <Cromaglious_> now passing Fallbrook, the arse of Camp Pendleton, USMC
[15:52:21] <_methods> lofting can be an experience some times
[15:54:17] <_methods> ssi: what exactly are you doing?
[15:54:30] <_methods> i'm heading home now i'll see if i can help you out
[15:57:05] <ssi> I think I have it whipped into submission
[15:57:17] <ssi> the problem was that I'm trying to do several lofts along teh same guide curve
[15:57:23] <ssi> and I think it was "consuming" the sketch when I'd do the loft
[15:57:33] <ssi> so I have to make a new sketch and convert the curve over for each loft
[15:57:42] <ssi> this is all because I can't do weldments along a curve :)
[15:58:00] <ssi> so I have short tangent lines at every truss intersection, and weldments there so the trimming works,
[15:58:03] <ssi> then lofting between the tangent lines
[16:21:51] <ssi> https://pbs.twimg.com/media/CAP1n86XIAA6CAX.jpg:large
[16:21:56] <ssi> that took ENTIRELY too much effort to model
[16:22:59] <_methods> heheh
[16:23:35] <XXCoder1> crazy.
[16:23:44] <XXCoder1> way ti go though
[16:26:27] <ssi> it's fourteen weldment sections and eight lofts
[16:27:10] <_methods> you using the weldment pieces for cut list or something?
[16:27:12] <Cromaglious> DAM DAM DAM, Caddi looks like it blew a head gasket
[16:28:13] <furrywolf> water in oil?
[16:28:49] <Cromaglious> white smoke, steam blasting from between head and block
[16:29:11] <furrywolf> that's an odd way to fail, but I guess it's possible. heh.
[16:30:18] <furrywolf> sure it's head/block and not a nearby hose, intake gasket, etc?
[16:33:33] <furrywolf> ssi:
http://en.wikipedia.org/wiki/Aerokopter_AK1-3_Sanka apparantly you can buy complete helis with subaru motors. I did not know this. lol
[16:37:22] <furrywolf> " • Capable of Lifting it`s Own Weight" I'd hope it can do that, and some fuel and passengers too! :)
[16:37:43] <ssi> sounds like a desirable feature
[16:38:14] <furrywolf> I think what they actually mean is it has enough spare lift it could lift itself twice over.
[16:38:22] <ssi> also note that my weight, rotor diameter, and power numbers are pretty close to in line with what that thing is
[16:39:52] <furrywolf> I'm surprised they got something with an automotive engine type certified...
[16:40:55] <ssi> what makes you think it's certified? :P
[16:41:03] <furrywolf> lol
[16:41:19] <ssi> no telling what "designed to comply with ukrainian AP-27 rules" means
[16:41:22] <furrywolf> good point, that part of the world tends to do those things based on bribes, not standards. :)
[16:41:44] <ssi> I can design something that's "designed to comply with FAR Part 25 rules", but that won't make it certified
[16:43:01] <furrywolf> still, with all your complaining about subaru motors, there seems to be a remarkably large number of them in the air... and now I know of at least one commercial non-kit vehicle with them.
[16:43:26] <ssi> remarkably large compared to what?
[16:43:34] <ssi> there are a non-zero number of them flying
[16:43:50] <furrywolf> there seem to be thousands of them flying, from what I've found googling.
[16:45:35] <ssi> I'm not sure exactly how you arrived at "thousands"
[16:46:19] <furrywolf> extensive googling and mental counting?
[16:46:33] <ssi> you mentally counted thousands of examples of airworthy subaru installations?
[16:47:15] <ssi> or is this just more "I can't stand to be wrong" arguing for the sake of arguing
[16:49:02] <furrywolf> http://www.sdsefi.com/aircraft.html ten listed just on that page, using that manufacuter's efi equipment...
[16:49:52] <ssi> k, that's ten
[16:50:04] <ssi> you have somewhere between 1990 and 9990 left to account for
[16:50:33] <ssi> there's somewhere around 40k experimentals flying in the US total
[16:50:41] <furrywolf> that's left as an exercise for the reader.
[16:50:52] <ssi> oh no, I'm not disproving your wild claims for you
[16:53:33] * furrywolf notes experimental aircraft aren't limited to the US
[16:54:00] <ssi> so there's ten in the US and eight thousand in the ukraine
[16:54:00] <ssi> got it
[16:54:22] <furrywolf> lol
[16:54:40] <furrywolf> I'm not going to waste the time needed to compile a list of them.
[16:55:09] <ssi> that's good, because it doesn't matter
[16:55:16] <ssi> I'm not using one, neither are you
[16:55:49] <furrywolf> I'm tempted to make a flying subaru just to annoy you.
[16:55:58] <ssi> please do
[16:56:02] <ssi> it certainly won't annoy me
[16:56:11] <furrywolf> r/c. I wouldn't get in anything that I build just to annoy someone. lol
[16:56:14] <ssi> and I certainly won't endeavor to help you make better choices with your money
[16:56:43] * furrywolf knows plenty of people who always go "it'll be fine!", and they're all covered in scars and/or dead
[16:57:18] <ssi> there are plenty of those people who said that about auto conversions
[16:58:07] <ssi> but it's ok
[16:58:22] <ssi> you're willing to risk your anonymous internet tough-guy persona on it, but you won't risk your life on it
[16:58:27] <ssi> that's the smart money
[16:58:50] <furrywolf> I think they're safe if carefully designed and engineered. A quick hack job to prove a point is not carefully designed and engineered.
[16:59:13] <ssi> if it's not safe because it's a quick hack job, it hardly proves the point
[16:59:33] <furrywolf> maybe someday I'll have the time and money to build an actual airworthy craft, but not now.
[17:00:00] <furrywolf> I can see in my head how to build every part of it except the main rotor blades... they exceed my manufacturing skills.
[17:00:48] <ssi> they're actually pretty easy
[17:01:12] <furrywolf> at a quick pulled-from-my-ass guesstimate, there's several tons of force trying to pull them outwards, and they're continually getting a lot of nasty vibration and flexxing.
[17:01:20] <ssi> they have to be strong in tension
[17:01:27] <ssi> they actually get all their stiffness from centrifugal force
[17:02:10] * furrywolf wonders what the laws on building a 1000lb r/c heli are
[17:02:20] <ssi> they're pretty solidly against it :P
[17:03:04] <ssi> 55lb is the legal limit
[17:03:11] <furrywolf> they are? they seem to have no problem with using giant r/c craft to murder people in other countries...
[17:03:33] <ssi> hm, I can't imagine a situation where the government operated under rules different than that which it imposed upon its subjects
[17:03:58] <furrywolf> lol
[17:06:23] <furrywolf> the real fun challenge would be to make one fly using as many original automotive parts as you can.
[17:06:31] <furrywolf> from the same car
[17:07:55] * furrywolf wonders what the cycle life of steering tie rod ends is...
[17:08:22] <_methods> galaxy 500 ultraheavylight
[17:09:10] <ssi> sometimes I feel like the mayor of crazytown
[17:09:20] <furrywolf> lol
[17:10:02] <ssi> you know what you really should get into
[17:10:04] <ssi> designing flying cars
[17:10:07] <ssi> that's right up your alley
[17:10:09] <_methods> hah
[17:10:12] <furrywolf> too much work
[17:10:17] <ssi> can't imagine why
[17:10:21] <furrywolf> too many very different design requirements
[17:10:22] <_methods> omg i made a bunch of parts for terrafugia
[17:10:29] <ssi> it's almost like you're suggesting that cars aren't designed to be airplanes
[17:10:54] <furrywolf> easiest flying car would be an autogyro with big wheels. :P
[17:11:45] <_methods> and that was like 3 years ago
[17:11:58] <_methods> still haven't seen their carplane yet
[17:12:45] <furrywolf> they built working fixed-wing planes in 20 hours on scrapheap challenge, how hard can a heli be? :P
[17:13:01] <ssi> it'll take at least 21 hours
[17:13:22] <furrywolf> lol
[17:19:36] <furrywolf> bbl, back to housework
[17:20:05] <Cromaglious> looking for a short term rental w/ trailer hitch
[17:22:25] <Cromaglious> Enterprise pickup $180 a week
[17:23:09] <_methods> lowes or home depot?
[17:23:15] <_methods> don't they rent trucks
[17:23:48] <Cromaglious> short term
[17:24:02] <Cromaglious> I need something to get me thru the week
[17:24:10] <Cromaglious> and weekend
[17:24:20] <_methods> oh
[17:25:16] <_methods> maybe try like a equipment rental place instead
[17:25:27] <_methods> sunbelt or whatever you local rental places are
[17:27:41] <Cromaglious> I like sunbelt
[17:28:20] <Cromaglious> neighbor was a backup hyundia, I'm trying to borrow
[17:29:55] <adb> https://www.youtube.com/watch?v=QsSchOiN8bY Aerocopter AK1-3.
[17:29:57] <Cromaglious> Old neighbor from the other side of him has a caravan his thinking of replacing.. I might end up with
[17:30:01] <furrywolf> http://fw.bushytails.net/amf230wtf03162015.png http://fw.bushytails.net/amf230wtf03162015-02.png ah, the things you see on flightaware... how many circles does it take YOU to intercept a radial? :)
[17:30:09] <Cromaglious> and a hitch is like $150 locally
[17:30:26] <furrywolf> I'll need to give that pilot crap next time I see him.
[17:30:58] <Cromaglious> can't even turn a even circle
[17:31:30] <furrywolf> on the bottom, the two full circles before tracking the radial... got to/from backwards? heh
[17:36:47] <furrywolf> that flight path... just ugh. must be a new guy. I'll see tonight if he ever manages to make it here.
[17:44:11] <renesis> dunno looks fun
[17:44:35] <renesis> you dont think he spun around twice just because?
[17:44:51] <furrywolf> lol
[17:45:03] <renesis> man i dont want to do dishes
[17:49:55] <furrywolf> bbl
[17:52:19] <Deejay> gn8
[17:52:57] <Cromaglious> hitch installed is $300
[17:54:01] <Cromaglious> man and I just got the replacement rear bulbs for it too, they came today

[18:20:56] <_methods> hehe they got a knight rider ronald reagan one too
[18:32:21] <_methods> http://cockrum.net/cnc.html#microscope
[18:33:29] <_methods> oh nm ignore it's a machtard
[18:34:53] <_methods> i got duped by hackaday i thought he actually was using it to set work offset
[18:35:11] <_methods> http://hackaday.com/2015/03/16/microscope-camera-for-zeroing-cnc-machines/
[18:35:14] <_methods> they fooled me
[18:35:20] <_methods> i should have known better
[18:44:27] <SpeedEvil> Well - SMOP and it is
[18:45:32] <CaptHindsight> it's close enough for +/- 1mm zeroing
[18:46:20] <SpeedEvil> Much closer than that
[18:46:41] <SpeedEvil> If you set focal length low enough
[18:47:19] <CaptHindsight> I thought they used the camera body as a touch sensor
[18:49:08] <CaptHindsight> you can see the parallax as they zoom in and out
[18:50:51] <SpeedEvil> Or simply highpass and look for in-focus
[18:51:28] <SpeedEvil> If you do actual focal plane reconstruction, you can get stupidly accurate results
[18:53:22] <SpeedEvil> i forget what the proper term is
[18:54:28] <SpeedEvil> http://www.ncbi.nlm.nih.gov/pubmed/25401577
[18:54:34] <SpeedEvil> Light ray field capture using focal plane sweeping and its optical reconstruction using 3D displays.
[18:55:18] <SpeedEvil> ah

[18:56:25] <rootB> Hey linuxCNC, what's a good CNC simulator?
[18:58:10] <alex4nder> rootB: linuxCNC is an awesome CNC simulator
[18:58:28] <rootB> uhm i'm more windows..
[19:00:03] <Valen> what do you mean by "simulator"
[19:00:28] <Valen> we have a camera on our mill btw, its <<<< 1mm
[19:00:33] <rootB> a program where i can run my G-Code
[19:00:51] <rootB> since im taking a G-code class
[19:01:31] <Valen> we lined it up on axis by moving the head up and down until when we were zeroed on a spot we stayed zeroed on the same spot when we went up 50mm
[19:01:54] <Valen> we used a 1080P camera, and it focused onto an area about the size of your fingerprint,
[19:02:10] <Valen> so the pixels per mm is roughly "a whole bunch"
[19:02:33] <Valen> rootB: do you want to simulate running a machine, or simulate seeing what the shape of the part you are making is
[19:02:38] <Valen> because those are different things
[19:03:18] <Nick001-shop> Can the new Debian 2.6.4 be upgraded to 2.6.7 and how to do it. Also, how do I get the same configurations that were in the Ubuntu disk, Like Stepper-XYZA?
[19:07:43] <SpeedEvil> Valen: Doing it right, you don't focus onto a spot one pixel wide.
[19:08:23] <SpeedEvil> Valen: you can do superresolution - you focus blurrily onto a spot that makes a circle 20 pixels wide, and then you can interpolate to basically ridiculous levels of acccuracy
[19:08:29] <SpeedEvil> What Kepler did.
[19:08:34] <Valen> yeah, but I have this on my mill right now
[19:08:50] <SpeedEvil> Or you just use a ball bearing as a reference.
[19:08:59] <Valen> and I can line up on a hole better than I can measure by any other means ;->
[19:09:05] <Valen> probably about .005mm
[19:19:21] <_methods> lol comes to LINUXcnc room then says i'm more windows
[19:19:31] <_methods> troll much
[19:22:27] <renesis> _methods: my guess is the majority of users are on both platforms
[19:23:03] <alex4nder> yah, with the plethora of CAM packages for Linux, nobody is on Windows. : |
[19:23:04] <renesis> cad/cam in linux is pretty crappy comared to free and easy to pirate options for windows
[19:23:11] <renesis> haha
[19:24:36] <_methods> so why not go to one of those many windows help rooms...........
[19:31:30] <renesis> because people who use linux are more likely to be better at windows, too
[19:32:41] <Cromaglious> well got a 4 inch gear to gcode out

[19:49:12] <_methods> i need to mod my mirror for that
[19:49:51] <Cromaglious> stick a closet rod down the middle in the back and pull the sides back a bit
[19:49:54] <SpeedEvil> God that could get you killed.
[19:50:09] <SpeedEvil> Install a 'fun-fair' variable geometry mirror.
[19:51:26] <Cromaglious> most of those, were using Stainless steel instead of glass mirrors when I went through them
[19:59:42] <SpeedEvil> Oooh.
[19:59:58] * SpeedEvil wonders if doing that at a restaraunt bathroom could actually improve profits.
[20:00:10] <SpeedEvil> 'yes, you can order desert'
[20:00:47] <Cromaglious> heh
[20:04:58] <_methods> hahah
[20:09:23] <CaptHindsight> Valen: how was your summer?
[20:10:11] <Valen> not too bad,
[20:10:17] <Cromaglious> ok now it pockets then cuts the hole, then cuts it out
[20:10:18] <Valen> how was your winter? lol
[20:12:10] <CaptHindsight> cold, cold and cold :)
[20:12:38] <CaptHindsight> finally hit 70F today (~20C)
[20:13:43] <Cromaglious> 95 in Escondido
[20:13:47] <Cromaglious> today
[20:15:14] <Cromaglious> hmm
[20:15:36] <CaptHindsight> "yeah but that's a dry heat"
[20:15:47] <_methods> heheh
[20:16:02] <_methods> it's not the heat it's the humidity
[20:16:21] <Cromaglious> pretty much... It was only 90 in the marine layer other side of the hill
[20:31:03] <tjtr33> CaptHindsight, weather so nice i got in weed-n-feed before sundown :) i figger the cold snap tomorrow will make rain outta this warm southern air.
[20:34:10] <tjtr33> CaptHindsight, this came in from DE,
http://www.asus.com/us/Motherboards/M5A88V_EVO/ which processor would you reccommend?
[20:50:56] <Jymmm> renesis: The SSD's are brand new, but only come with a 30/30 warranty
[20:52:22] <Jymmm> renesis: As n 30 seconds or 30 feet, whichever happens soonest.
[21:15:44] <CaptHindsight> tjtr33: how fat do you need it?
http://www.amd.com/en-us/press-releases/Pages/amd-unleashes-2013jun11.aspx
[21:19:54] <tjtr33> CaptHindsight, thanks. isnt new = risky? i found 'AMD ATHLON II X2 250 3.00GHZ ADX2500CK23GM SOCKET AM2+/3 CPU PROCESSOR' .
[21:20:19] <tjtr33> i think i'll try that
[21:20:44] <CaptHindsight> what the price?
[21:21:05] <CaptHindsight> http://www.amd.com/en-us/products/processors/desktop/fx#
[21:23:37] <tjtr33> 22$ free shpg USA
[21:23:43] <CaptHindsight> sold
[21:24:02] <tjtr33> :) and a radeon card from tiger down in naperville
[21:26:17] <CaptHindsight> tjtr33: memleak fixed all the RTAI issues last year, so any APU works well (or we haven't found one yet that doesn't)
[21:29:05] <tjtr33> oh cool, is that a special branch for what memleak did? ( and Thx memleak!)
[21:29:44] <CaptHindsight> https://github.com/NTULINUX/RTAI
[21:32:27] <CaptHindsight> the next stable version of RTAI should have much reduced latencies, but it will require to be built for each type of x86 processor
[21:33:20] <Cromaglious> freqen heck... my "new" usb 3 card PCIe keeps dropping the external 1.5TB drive connection
[21:35:47] <CaptHindsight> tjtr33: what would be more useful to you on that i.mx6+fpga board, 50 pin anything IO connectors or the 26pin on the 6i25?
[21:36:32] <Cromaglious> OK... SketchUcam likes to cut gears over X pitch... anything smaller than .01 gives it massive heartburn
[21:36:40] <Cromaglious> 0.01"
[21:37:55] <tjtr33> CaptHindsight, 50pin and ethernet for me, i'll post on #openlunchbox thx
[21:39:32] <CaptHindsight> tjtr33: like the 6i24
[21:39:56] <CaptHindsight> 72 I/O bits available on three 50 pin
[21:43:18] <tjtr33> well, like the 5i20 ( i been here too long :) & thx ( i was off ordering from Tiger, dummies wouldnt let me order online and pickup at store :p
[21:43:59] <tjtr33> and next day comes friday ? they on another planet?

[22:24:14] <ssi> hi
[22:35:21] <ssi> holy crap on my 5k imac if I set retina mode resolution for windows
[22:35:26] <ssi> solidworks gets crazy tiny icons :(
[22:35:30] <ssi> but looks amazing otherwise
[23:08:20] <Cromaglious> http://hackaday.com/2015/03/12/new-reprap-with-integrated-case-oddly-called-case-rap/
[23:08:25] <Cromaglious> nice idea
[23:09:15] <furrywolf> I think that falls into "clever, but useless".
[23:09:41] <CaptHindsight> reminds me of the 45rpm record players of the 60's with built in speakers and tube amp
[23:10:25] <Cromaglious> actually case rap would be nice to demo... laptop and case rap
[23:11:00] <furrywolf> you should build one that prints extensions to the axis and builds itself larger as long as you keep supplying plastic to it.
[23:11:36] <furrywolf> like tower cranes that assemble themselves
[23:12:15] <furrywolf> bonus points if it includes some mechanism to move itself about and consume found plastic objects
[23:12:46] <CaptHindsight> I want one that is self aware so it can tell people to stop hyping glue guns
[23:13:11] <furrywolf> lol
[23:13:30] <furrywolf> you want the hipster model. it'll print "don't buy 3d printers" in a very ironic typeface.
[23:14:02] <CaptHindsight> "3D printers are not just glue guns"
[23:15:38] <furrywolf> I wonder how much accuracy you could get arc-fusing mig wire to form an object...
[23:16:17] <CaptHindsight> http://techcrunch.com/2014/11/17/students-build-out-with-metal-using-a-mig-welder-and-an-off-the-shelf-printer/
[23:16:29] <CaptHindsight> http://www.3dprinterworld.com/article/open-source-3d-metal-printer-based-mig-welders
[23:17:58] <furrywolf> just from the text (not watching video), it doesn't mention at all what kind of accuracy/finish/etc you get.
[23:18:49] <CaptHindsight> http://3dprint.com/wp-content/uploads/2014/11/met3.png
[23:19:47] <furrywolf> crap, then. :P
[23:19:57] <furrywolf> but that looks like it's just using an off-the-shelf mig power supply...
[23:20:08] <CaptHindsight> yes
[23:20:30] <CaptHindsight> with better guns, power supplies and gas it can be better
[23:21:14] <CaptHindsight> http://4.bp.blogspot.com/-yBXiJp6QEbU/VFVdoxNpvcI/AAAAAAAAFv0/DqaSt3pX4Ec/s1600/weld3d%2Bdiy%2Barc%2Bwelder%2Bmetal%2Bparts.jpg
[23:21:20] * furrywolf has filled enough holes to know what a standard mig welder does. heh.
[23:21:49] <CaptHindsight> https://www.youtube.com/watch?v=wOarxQRKW9o
[23:22:12] <furrywolf> I wonder if you could do something clever like laser it instead of arc it...
[23:22:29] <CaptHindsight> DMLS
[23:23:34] <CaptHindsight> http://www.partsondemand.us/dmls/
[23:23:36] <furrywolf> that's for sintering metal powder. I mean using a laser to melt the tip of a wire to the surface.
[23:24:06] <CaptHindsight> e-beam
[23:24:38] <furrywolf> that gets complicated and dangerous.
[23:25:45] <CaptHindsight> https://www.youtube.com/watch?v=A10XEZvkgbY
[23:25:56] <CaptHindsight> Electron Beam Additive
[23:26:39] <furrywolf> I don't watch videos without a very good reason...
[23:27:29] <CaptHindsight> I avoid Irish Pubs
[23:27:42] <Jymmm> theres a dildo in it for 0.00000000000000002 nS
[23:27:46] * furrywolf avoids all pubs
[23:28:50] <furrywolf> videos tend to piss me off more often than not. getting information by listening to someone talk has been a bad idea ever since writing was invented many ages ago...
[23:29:46] <CaptHindsight> I miss informational radio programs, especially cooking and home remodeling
[23:32:21] <furrywolf> I'd much rather have a written article with pictures than a video. except for a few circumstances, like demonstrating complicated movements, text and pictures is a much better means of conveying information.
[23:32:38] <Jymmm> What purpose would it serve to have only a single leg of a secondary xfmr feed back into the primary?
[23:32:44] <furrywolf> you can read text much, much faster than listening to someone talk, you can skim, jump around, etc, etc...
[23:33:03] <Jymmm> No way
[23:33:44] <furrywolf> Jymmm: I'm not sure what you mean. do you mean putting it in series, so the voltage adds/subtracts from the primary voltage? (commonly called bucking/boosting, no relation to the switching topologies) Or just so they share a common lead?
[23:34:44] <Jymmm> pri and sec are 100% isolated from each other, except one single leg fro the secondary is being fed back to the primary side circuitry
[23:35:52] <furrywolf> could be so they have a common reference, or if this is something complicated and not just a mains power transformer, could be feedback, current sense, or such...
[23:36:13] <Jymmm> It's al electric fly swatter
[23:36:16] <Jymmm> an*
[23:36:25] <Jymmm> stun gun if you will
[23:36:31] <Jymmm> VERY simple circuit
[23:36:42] <furrywolf> does it have a trivially simple circuit board, with that winding fed back to the bases of the transistors?
[23:37:12] <furrywolf> it's part of the oscillator, then.
[23:37:37] <Jymmm> It goed thry a resistor and then into the primary, not the Q
[23:39:06] <furrywolf> draw a schematic and figure it out. :P
[23:40:16] <Jymmm> on eless cap and diode than this
http://cdn.instructables.com/F67/1UUY/FL4SYYBL/F671UUYFL4SYYBL.LARGE.jpg
[23:41:00] <Jymmm> http://www.alldatasheet.com/datasheet-pdf/pdf/138811/JIANGSU/D965.html
[23:41:31] <furrywolf> I have an electric flyswatter somewhere... never even put batteries in it. Got it for $1.99 on sale at harbor freight.
[23:41:47] <Jymmm> Yep, that be it
[23:42:13] <Jymmm> they work good
[23:42:15] <furrywolf> somehow every time I have a mosquito to swat, I just use a random object or finger.
[23:42:39] <Jymmm> Toss a UV led behind one =)
[23:42:53] <furrywolf> heh
[23:43:20] <furrywolf> I have a couple bug zappers with uv fluorescent bulbs... they seem ineffective. they zap bugs excellently, but the bugs only get zapped when they randomly fly into it...
[23:43:34] <Jymmm> ah
[23:44:48] <furrywolf> now, my non-UV metal halide worklights seem to attract bugs instantly.
[23:44:55] <furrywolf> I should combine these somehow.
[23:47:29] <Jymmm> there ya go
[23:47:53] <Jymmm> Im just trying to reduce the HV, well make adjustable
[23:50:28] <furrywolf> because it works too well?
[23:51:03] <Jymmm> To wire to desk/chair ;)
[23:51:32] <furrywolf> someone once suggested using them for paddling people. :P
[23:52:04] <Jymmm> It break in an instant - cheap plastic
[23:52:29] <furrywolf> lol
[23:53:03] <furrywolf> I don't think impact force was the goal.
[23:53:24] <Jymmm> I'm also (now) curious about the the cap/diode doubles voltage.
[23:53:48] <Jymmm> It have to be, you can't touch both by hitting someone woth it
[23:56:59] <furrywolf> bbl, wolfy bedtime
