02:20 rue_house nothing as hard as pull starting an electric
02:20 GargantuaSauce at least both product descriptions they mashed together are for pumps
02:20 rue_house that said, I had a few that needed a spin-start
02:21 GargantuaSauce i've seen very...diverse combinations
02:27 GargantuaSauce anyway as far as chinese fleabay listings go, i think inverter girls takes the cake
02:28 GargantuaSauce http://i.imgur.com/OwtQT.jpg
02:39 RifRaf rue_house, got all limit switches and motors working smoothly
02:39 RifRaf goes to home position nicely, one axis after the other
02:41 GargantuaSauce that's always weirded me out, i dont get why it doesnt home all 3 at once
02:41 GargantuaSauce youre using marlin right?
02:43 RifRaf yes its marlin
02:47 rue_house wow that was a hack and a half, I wonder if this will work
02:48 GargantuaSauce hows your arm control coming
03:02 rue_house after some hacking I just got the interpolator working
03:03 rue_house I had to use a global :(
03:03 rue_house I wanted to be able to make up a motion sequence, but I'll do that tommorow
03:03 rue_house or when the faire opens
03:30 RifRaf rue_house, you going to exhibit your arm at the fair?
03:38 GuShH rue_house: you know if general purpose VFDs can be used as a simple single phase output without triggering faults?
03:38 GuShH Startvert iE5
04:12 tweeky Hey guys, wondering if someone could help me out. I want to purchase a few high torque motors and write a program to track stars with my telescope. Problem is atm, the scope has a 40cm round base, and it would be perfect if I could buy a roll of like, cog teeth stuff, super glue it around its base so the 12v motor can grab it. I cant find this 'tape' stuff anywhere, don't know what it's called and if it even exists? Any help apprec
04:19 i_tarzan_ it does not exists
04:20 i_tarzan_ if so all dentistry work would be perfect, but nope
04:21 tweeky damn
04:22 tweeky I mean it's like getting a cars engine belt and flipping it inside out and using that, but its teeth are too large, not enough accuracy for a scope.
05:06 zap0 gyro/stabalizers for a steady cam rig, anyone know a cheap solution?
05:07 theBear erm, however they did old ones... nothing electronic/active in those
10:14 robbor hey.. i am developing swarm robots where the primary aim is to get to a place and capture pictures from there... it would be great if someone could guide me in this regard
10:15 robbor i just need help in coding
10:16 DagoRed That's a major part of that project.
10:17 robbor yes.. if you could just help me get a start... i would be very thankful
10:18 robbor it can be in c/c++
10:19 robbor like how do you use it on Player Stage etc.
