00:35 GargantuaSauce_ pretty much just that
00:35 GargantuaSauce_ and lots of wikipedia
00:35 Loshki :-)
00:35 GargantuaSauce_ and also bugging a friend who is doing his masters :x
00:36 Loshki Do you have a local hackerspace? Good place to pick brains for all sorts of skills, esp. mechanical..
00:36 GargantuaSauce_ no, i live in a "city" of 35k
00:37 GargantuaSauce_ been considering starting one but it would be pretty hard to get off the ground
00:37 GargantuaSauce_ and a huge timesink
00:37 Loshki True, and no-one retires rich from one, either...
00:37 GargantuaSauce_ indeed. when i am a gazillionaire i'll start an educational foundation in that vein
00:38 Loshki And I will run a small avant-garde theater in San Francisco...
01:03 mrdata should i design a terminator?
01:04 anonnumberanon too hard
01:05 GargantuaSauce_ isnt it just a resistor with a value equal to the characteristic impedance of the transmission line?
01:33 mrdata lol
02:37 MrCurious so just what is required to get a robot to run amok properly other than repeatedly running into walls?
02:38 Hyratel1 you seem to have an unrealistic definition of "run amok"
02:38 MrCurious what would a realistic definition be :)
02:38 Hyratel1 run into walls when you want it to do something else :7
02:40 MrCurious video of the hour https://www.youtube.com/watch?v=vLbwFxIQ_Mo
02:51 MrCurious https://www.youtube.com/user/LastWeekTonight
02:52 MrCurious fuck me... russia has lost control of a pod of fucking geckos
02:53 MrCurious you cant watch videoos of them #### then toss the aside.... they are not kardashians...
03:02 MrCurious "its life Jim, but not as we know it"
09:43 rue_mohr2 geckos eh?
12:56 MrCurious good morning vietnam
12:59 GargantuaSauce_ it's the middle of the night there!
12:59 GargantuaSauce_ idiot
13:01 MrCurious heh
13:02 GargantuaSauce_ https://developer.nvidia.com/jetson-tk1
13:02 GargantuaSauce_ lord lead me not into temptation
13:06 MrCurious looks nice
13:07 MrCurious but would need those cuda cores for something other than graphics...
13:07 GargantuaSauce_ hMmmm whatever would i do with a quarter teraflop
13:43 MrCurious http://hackaday.com/2014/08/01/solar-powered-lawn-mower-cuts-the-grass-so-you-dont-have-to/
16:21 i-make-robots Hey, robots. Just to let you know Makelangelo now supports Adafruit Motor Sheild 2 and Arm3 now supports RAMPS 1.4. Thanks for the great suggestions!
16:29 deshipu what's makelangelo?
16:39 MrCurious no idea
16:40 MrCurious looks to be a dangled pen drawing system
16:47 MrCurious i would have just grabbed an arduino mega, a 3d printer shield supporting 6 stepper driver boards, slapped that shit together and called it a day
16:48 MrCurious but if etch a sketch is your thing :)
16:54 i-make-robots Your disdain is tangible, and bring down the group as a whole.
16:55 i-make-robots You would have, but you didn't. There are >600 makelangelos around the world now.
16:56 MrCurious i guess this means we arent going to be cuddly friends :(
16:56 MrCurious sorry for pointing out that COTS components could do the same as what you have
16:56 i-make-robots we certainly can be :) Encouragement and positivity go a long way. I'm tired of seeing "your solution is stupid, I would have done this" which is like saying "I'm smarter than you, even though you got the job done."
16:57 MrCurious but by all means, treat optimiation as criticism
16:57 MrCurious optimization
16:57 i-make-robots if it's stupid and it works, it isn't stupid.
16:57 i-make-robots as it happens they DO use 3d printer shields.
16:57 MrCurious then you miss the point of constructive criticism. please resume your marketing pitch
16:57 i-make-robots I switched to a cheaper shield in the v2.5 because the market demanded it.
16:58 MrCurious so you laser cut some wood, bundle some COTS parts and string, and that is the kit?
16:59 i-make-robots there's also the software.
16:59 MrCurious well, carry on the maker revolution! :)
16:59 i-make-robots that's the spirit!
16:59 i-make-robots thank you.
17:00 i-make-robots what do you make?
17:00 MrCurious CNC machines, 3d delta printers, omni wheeled robots with 5dof arms with positional accuracy
17:01 MrCurious but i do it by machining the parts myself
17:01 MrCurious only been in the hobby 2 or 3 years...
17:01 i-make-robots I'd like to see your 3dof arm.
17:01 i-make-robots er, 5dof
17:02 MrCurious look up owi robotic arm
17:02 MrCurious i am in this all for the learning. i am sure your 600 sales will bring you an IPO soon...
17:03 i-make-robots these are great! how come I've never seen you at a maker faire?
17:03 MrCurious not in the sales business
17:03 MrCurious its just a hobby for self improvement
17:03 i-make-robots i dont' see your arm here. I see an armatron knockoff, but it's not on an omni wheel bot.
17:05 MrCurious i am keeping it mum for now... would hate for some hack to repackage it and sell the idea
17:05 i-make-robots so your arm isn't on this site?
17:05 MrCurious i told you i dont think we will be friends, and i dont think a pissin contest will help us bond
17:05 i-make-robots http://www.owirobot.com
17:06 MrCurious its there, but i would source it elsewhere
17:06 MrCurious save some $$$
17:06 i-make-robots I don't care. I just want to see it! I love robot arms.
17:08 MrCurious http://www.aliexpress.com/wholesale?SearchText=printer+3d+stepper&initiative_id=QRW_20140802144926&productId=1518829273
17:08 MrCurious or
17:08 MrCurious http://www.aliexpress.com/item/2pcs-lot-3D-printer-engraving-machine-stepper-motor-expansion-board-V3-4-stepper-motor-drive-module/1855285618.html
17:09 MrCurious shoud work for your kit nicely
17:09 i-make-robots you said "omni wheeled robots with 5dof arms with positional accuracy". Was there a typo? Maybe I misunderstood and the omni is separate?
17:09 MrCurious yes, that rolls it around
17:10 MrCurious moves via r, theta or rotation commands
17:10 i-make-robots cool. where can i see a pic or video? I'm searching but I'm not finding
17:10 MrCurious i am sure its on the web somewhere
17:10 i-make-robots If you say so.
17:12 MrCurious https://www.flickr.com/photos/89612859@N04/sets/
17:12 MrCurious knock yourself out
17:13 MrCurious so what do you build? just the etch a sketch thing? or other stuff too
17:15 MrCurious the robot is still pending completion. just managed to source a cheap lcd + driver board for its face, kinect for its vision,, and a quad core 2gh arm for its central cpu
17:16 MrCurious ccheapest source for lipo batteries i could find was MBP knock off battery packs
17:19 MrCurious right. we were at what you build
17:22 deshipu MrCurious: what will it do?
17:22 MrCurious teach me how not to make robots
17:22 GargantuaSauce_ dance like there's no tomorrow
17:23 MrCurious its just a learning device
17:23 MrCurious you have to build something, make mistakes, learn...
17:23 deshipu MrCurious: but to design a contraption, you need to have at least a vague idea of what it would be used for?
17:24 deshipu MrCurious: otherwise how do you decide on tradeoffs?
17:24 MrCurious design? i just pulled it out of my butt
17:24 MrCurious once i have a clue on how to actually make robots, THEN i can design for purpose
17:25 MrCurious this was just to teach me about encoding arm movements, then learning how to choreograph possitioning
17:25 deshipu MrCurious: well, in order to learn to design robots, you obviously should at least try designing them? :)
17:25 MrCurious to move a kinect around to let me learn its SW
17:25 MrCurious i am a programmer... this is just fun to blow off steam
17:25 deshipu sure, same here
17:25 deshipu except I started several weeks ago, not several years
17:26 deshipu I probably still take it too seriously :)
17:27 MrCurious the purpose of the first robot was just to get something working that i could get to the part i really wanted. programming it
17:29 MrCurious suppose i could cut up some aluminum, bundle some toy arms, magnets, and hall effect sensors steppers, omni wheels, an arduino, an odroid-u3, 2 MBP batteries, and sell it as a robot kit...
17:30 MrCurious might be able to sell a few
17:32 deshipu a bought robot is not fun
17:32 deshipu unless it has death rays
17:32 deshipu death rays make everything fun
17:33 MrCurious well its standard to add the lasers after market
17:33 MrCurious the included lasers always suck
17:33 i-make-robots I want to make robots all the time. To do that my robots have to sell so I can afford to make more. We are not so different, you and I.
17:33 deshipu i-make-robots: you just want all the fun for yourself
17:34 i-make-robots oh no! kids love the drawing robot, and it teaches the start of 3d printing and robotics. Remember a 10 year old can't code like you can, they need something accessible.
17:34 deshipu a 10 year old also can't pay for the kit
17:34 i-make-robots when i was 10 we wrote LOGO commands to move a turtle on a commodore 64. what do kids have today? minecraft? Ain't no programming there.
17:35 i-make-robots deshipu - that's why i sell to schools and help 30 kids per class per year.
17:35 deshipu logo never disappeared, people still use it
17:35 deshipu and the turtle module in python
17:36 i-make-robots I'm sure it's out there somewhere.
17:36 MrCurious suppose i could add a retractable marker onto mine's omni platform, and make it a draw bot as well. it already supports logo style movement commands
17:37 i-make-robots nice. if you have a pen drawing well it's a small step from there to 3d printing.
17:37 MrCurious or a retractable multi color pen, or even an inkjet...
17:37 deshipu MrCurious: it looks a little big for letting a 10 year old program it
17:37 MrCurious wifi...
17:37 deshipu MrCurious: especially when you make a mistake in the program...
17:38 i-make-robots http://www.marginallyclever.com/shop/robot-arms/palletizing-robot-1 lately I'm improving this.
17:38 i-make-robots i envy your machinist skills.
17:38 MrCurious srsly.. you dont let them upload base firmware, you let them upload a user level program that wont fail the system on errors..
17:38 i-make-robots so true.
17:39 MrCurious 10 year olds suck at playing core-war
17:39 deshipu for a moment I thought it would write "help"
17:39 GargantuaSauce_ F R E E M E
17:39 deshipu "I'm trapped in a robot factory"
17:41 MrCurious holy shit. CNN is now reporting that several robotic manufacturing plants in china have lost control of the facilities. the manufacturing robots are making something.... crap did we just hit singularity?
17:41 deshipu I, for one, welcome our new robot overlords
17:44 MrCurious who here knows bat mans super power?
17:50 GargantuaSauce_ money?
17:53 i-make-robots MrCurious - aw, you got my hopes up with that CNN thing.
17:54 MrCurious money is correct. that is batman's super power
17:56 deshipu so what's his weak point?
17:59 GargantuaSauce_ relationships
18:00 MrCurious HAH
18:00 MrCurious he always falls for the bad girls
18:00 Tom_itx bat girls?
18:01 MrCurious girls that are batty?
18:11 i-make-robots I'm working on the theory that batman is a modern Dread Pirate Roberts. That's why he's different in every film. Alfred is totally insane and keeps recruiting minor league superheros to be the replacement when current batman either dies or retires.
18:11 Hyratel1 i-make-robots, that's actually canon per batman Beyond
19:20 i-make-robots Hyratel1 - TIL.
19:21 Hyratel1 yep
19:21 Hyratel1 it's in..
19:21 Hyratel1 I want to say within the first three eps that that's established
19:21 Hyratel1 three's a Hall Of Armor from the successors Bruce Wayne has trained
19:54 MrCurious ITS ALIVE! 1 axis of delta now moving under its own power
19:54 MrCurious should have all 3 working by night
19:56 GargantuaSauce_ https://www.youtube.com/watch?v=4XCUK0fpBT4
19:56 GargantuaSauce_ this is very silly
19:56 GargantuaSauce_ i love what its vibration does with the rolling shutter
21:36 MrCurious all 3 delta carriages running with driver
21:44 MrCurious did not know you hung out there Tom_itx
21:44 Tom_itx been there for ages
21:48 MrCurious cant wait to see my delta with the carriages running concurrently
