19:50 RifRaf cannot work out how to slow the loop down yet
19:50 RifRaf the servos are smooth with only a few movements, but the more i add the faster it has to go to do them all
19:51 RifRaf is simple, just dunno where its hiding
19:51 rue_house snap us a picture of the interface for setting up the motion seq
19:52 RifRaf hey i coded it all myself :P

21:51 RifRaf g'day shuggans
21:52 RifRaf looks like you have something all hooked up ready to go
21:52 RifRaf are you doing fets and relays?
21:52 shuggans yes
21:52 shuggans fets for pwm
21:52 shuggans later on
21:52 shuggans relays handle the 50 amps
21:52 RifRaf cool
21:53 shuggans 3 fets wires will handle 60, which is more than the relays
21:53 RifRaf i hope rue does not drag it out too long, have you got the relays going?
21:53 shuggans Im going out to the garage to drille 3 more holes for the fet board
21:53 shuggans brb
21:53 RifRaf k
21:53 RifRaf me too
21:53 shuggans no- just the coil circuit is wired
21:53 shuggans I have 10G wire for the rest, going to double up on it
21:54 shuggans brb
22:04 shuggans back
22:05 shuggans rif: how u like me solder traces on the fet board?
22:05 shuggans took an hour :P
22:07 RifRaf nice and heavy duty
22:07 RifRaf heh hope you didn't cook the fets
22:07 shuggans lol nah
22:07 shuggans put them in last
22:08 shuggans how do u make the PCBs tho, for future reference?
22:09 RifRaf first you sketch a schematic by hand, then put into cad, like eagle
22:09 RifRaf make prototypes, get final design made properly if you want it to last
22:11 RifRaf shuggans, my latest thing, http://imagebin.org/245097 http://imagebin.org/245098

22:17 RifRaf what one rue?
22:17 RifRaf rue_shop2 can you make shuggans thing work?
22:23 shuggans is 10G wire thick enough for this or do I need to go 8 or 6?
22:32 rue_shop2 shuggans, there you are
22:32 rue_shop2 where did you go for so long?
22:32 rue_shop2 shuggans, 10awg is fine
22:33 shuggans for 50 amps?
22:33 shuggans I was at work out of town all week
22:33 rue_shop2 shuggans, ok, from the battery (combined currents) they use
22:33 shuggans Igot a place where I am working though, so will be moving there soon. should be there by the 22nd, internet shortly after
22:34 shuggans ok. so 10awg is DEFINATELY good? no need to double up?
22:35 rue_shop2 huh, I misplaced it
22:35 rue_shop2 its 8 or smaller
22:36 rue_shop2 the motors on mine use ~14
22:36 shuggans ahhh
22:36 shuggans and they are similar motors right?
22:36 shuggans just being cautious bc these relays that came on the chair are 50 amp
22:37 rue_shop2 disability chair
22:37 shuggans I think I can double up if need be
22:37 rue_shop2 my motors are 24V, I cant read the current from them
22:37 shuggans yes - pride jazzy powerchair
22:39 Tom_itx rue_shop2, what you workin on tonight?
22:41 shuggans gna go find a soldering gun - this iron isnt cutting it
