00:14 RifRaf heh rue is beaten by a reprap, have faith, we can fix it
00:43 Jak_o_Shadows wooo stepper motor working
00:43 Jak_o_Shadows testing out one of the actual ones i'm gonna use
01:01 RifRaf for robot or reprap?
01:14 Jak_o_Shadows reprap
01:21 RifRaf cool, am printing again today thanks to some new clear abs arriving
01:22 Jak_o_Shadows Fasteners are annoying
01:22 RifRaf rather hard to see though
01:23 RifRaf tasteners are good, don't be forcing them
01:23 RifRaf fasteners*
01:25 Jak_o_Shadows It's hard sourcing them.
01:25 RifRaf wat you need, hove lots here
04:13 SquirrelCZECH .buffer 15
04:16 data flu
16:21 SquirrelCZECH anybody some nice way how to get intersection points of line and circle?
16:21 uirrelCZECH got lost in his calculat
16:21 SquirrelCZECH more like I believe it's right but it returns bullshists
16:22 SquirrelCZECH P.S: I've got coord of the circle, radius, and two points of the line
16:25 wolfmanjm http://mathworld.wolfram.com/Circle-LineIntersection.html
16:39 SquirrelCZECH fuuu
16:39 SquirrelCZECH they do it at circle at (0,0(
16:42 SquirrelCZECH ok
16:42 SquirrelCZECH someeeeething is terribly wrong
16:42 uirrelCZECH found another link where is equation he
17:59 SquirrelCZECH http://projects.veverak.org/Arduino%20Tank/test5.png tadaaaaah
17:59 SquirrelCZECH fulyl scripted
18:00 SquirrelCZECH just setup dimensions for wheels, put them in the space and script calculates the rest
18:01 Jak_o_Shadows What's this in?
18:02 SquirrelCZECH openscad
18:03 Jak_o_Shadows ah
20:14 rue_more SquirrelCZECH, you use the formula in my little black book
22:00 Rif rue_more, any progress on reprap or did you send it flying off the desk?
22:06 rue_more hell I'm not working ont hat thing tonight
22:06 rue_more I'm working on another hopeless project, tiny26 i2c
22:06 rue_more salve
22:24 Rif ah the soothing salve
22:37 rue_more funny enough, its easier to bitbang it than to use the usi
23:35 GuShH rue_more: the auto lathe spindle motor works! but it needs new bearings. I noticed they added an extra power feed to one of the tailstocks and that's because they wanted to automatically back-out threading dies, the feed unscrews it.
23:36 rue_more huh
23:36 rue_more what kinda motor?
23:36 GuShH the spindle has a tiny 1hp 3 phase 380vac
23:36 GuShH the main motor was 2hp most likely but it's gone
23:36 rue_more huh
23:37 GuShH (it uses two)
23:37 GuShH I have the belt, and the main pulley ... I just need to find a motor and make or find a suitable V pulley to try it out
23:38 rue_more hmm I didn't show you guys the pullies I made
23:38 GuShH don't think so
23:39 GuShH you make fun of that big old lathe but I could swing some big ass pulleys on that thing! -- assuming the motor works, haven't probed it yet
23:39 rue_more yes and no, Its for specific things
23:39 ShH g
23:41 GuShH if I had a suitable clutch I would totally mount a small 2 stroke engine as the power source for that lathe
23:41 GuShH for fun.
23:41 GuShH don't tell me you wouldn't find that amusing!
23:42 Jak_o_Shadows woukd you want a bif flywheel for that as well?
23:42 GuShH the 3 jaw chuck acts as one, doesn't it
23:43 Jak_o_Shadows dunno
23:44 GuShH Can't find any videos showing a gas powered lathe
23:46 rue_more https://www.youtube.com/watch?v=P4qB6n1cm04
23:46 rue_more GuShH, ^^
23:46 GuShH nope
23:46 GuShH that is not a lathe
23:46 GuShH just a slightly modified vehicle.
23:46 GuShH I mean a real lathe, gas powered.
23:47 Jak_o_Shadows Don't lathes turn faster than that?
23:47 GuShH he also lied on the title, that car is under 100hp
23:47 GuShH for wood? yeah, but the bigger your OD the slower your RPM, you just care about SFM
23:47 Jak_o_Shadows yeah
23:49 GuShH you can always go faster, but you gotta remember... that IS wood.
23:49 GuShH I've had wood fracture and fly off
23:49 GuShH meh haven't used the wood lathe in a long time, will probably sell that
23:51 rue_more https://s3.amazonaws.com/lumberjocks.com/mqs5fcu.jpg
23:52 GuShH heck yeah!
23:55 mrdata wood is such a nice material though
23:56 GuShH mrdata: is it..
23:57 GuShH rue_more: can we see ze-pulleys?
23:57 rue_more yes, but
23:57 rue_more its a challange
23:57 rue_more see, when I wake up, its dark
23:57 rue_more when I leave for work, its dark
23:57 rue_more when I get home, its dark
23:57 rue_more so I can do it on the weekend*
23:58 GuShH the invention is called "a flash"
23:58 rue_more yea, if it cant see it wont focus
23:58 GuShH flashlight!
23:58 mrdata GuShH, of course you should prefer a nice even grain, and not all kinds of wood have that
23:58 rue_more I have lots of images so blurry you can make anything out if you dont mind me posting soemthing at random
23:58 rue_more *its also cold out, and I _AM_ in my pajamas
23:59 GuShH bah
