[00:25:49] <restorer> dammit
[00:26:18] <restorer> ctrl != shift
[00:58:07] <Hyratel> RyanS, no
[00:58:45] <Hyratel> motor encoders are generally zero-torque designs, either optical or sensing-magnetic
[00:58:57] <Hyratel> and all the 'abcklash" is zero-sum
[00:59:01] <Hyratel> backlash
[00:59:35] <Hyratel> backlash in a geartrain is always zero-sum
[00:59:44] <Hyratel> setting aside gear wear
[01:02:44] <RyanS> you just account for the 3:1 reduction in software ? actually no because the motor spins at a 3:1 rate so doesn't matter where encoders go?
[01:02:59] <Hyratel> backlash is zero-sum
[01:03:23] <Hyratel> unless you have a movement that includes a movement that's less than the total system lash, it's ignorable
[01:04:53] <RyanS> makes sense, my lathes DRO doesn't care about handwheel backlash
[01:05:15] <Hyratel> that's why I call it 'zero sum'
[01:05:30] <Hyratel> once it's taken up, it only reappears if you drive the system back the other wya
[01:05:41] <Hyratel> and in the exact same amount
[01:06:06] <RyanS> its a zero sum game... lol
[02:30:09] <deshipu> veverak: yeah, servo blaster just works
[04:37:17] <veverak> nice
[05:26:59] <Jak_o_Shadows> ah hell
[05:27:06] <Jak_o_Shadows> I reprogrammed the 3D print atmega
[05:28:52] <Jak_o_Shadows> Instead of the one for the stewart platform
[05:36:25] <deshipu> Jak_o_Shadows: time for firmware upgrade, I guess
[05:38:34] <Jak_o_Shadows> haha.
[05:38:48] <Jak_o_Shadows> From 3d printer to 6 channel ADC
[05:45:08] <deshipu> well, put the printer firmware back
[07:30:12] <robotustra_> https://www.youtube.com/watch?v=ppMuu1X08T8
[07:31:49] <deshipu> O.o
[07:32:26] <robotustra_> lol
[07:33:22] <deshipu> looks quite.... complicated
[07:34:27] <robotustra_> and ugly
[07:34:37] <jhylands> his wiring leaves something to be desired
[07:35:41] <jhylands> I like his use of plastic wiring bundles
[07:36:44] <robotustra_> yeah, I also plan to use curragated pipes
[07:37:20] <jhylands> love that motor whine
[07:37:36] <jhylands> I wonder what frequency he does his PWM at
[07:38:44] <deshipu> from the sound of it, some 10Hz ;)
[07:38:48] <jhylands> heh
[07:59:58] <robotustra_> 10kHz?
[08:00:03] <robotustra_> http://playground.arduino.cc/Main/TimerPWMCheatsheet
[08:01:13] <robotustra_> sorry 10 Hz
[08:01:15] <robotustra_> :)
[08:37:47] <robotustra_> "to make it human-like as possible"
[08:40:00] <deshipu> wasted opportunity
[08:40:19] <deshipu> they could have made it dragon-like
[08:41:49] <robotustra_> deshipu: like this?
http://robotustra.ca/maholet2
[08:42:10] <deshipu> isn't that a fly?
[08:42:25] <robotustra_> dragon fly :)
[10:36:40] <maiden> ping
[10:38:19] <robopal> bong
[10:54:01] <maiden> that must be the standard Borg reply to ping..
[11:02:59] <deshipu> splortf
[11:03:45] <deshipu> maiden: the standard Borg reply to ping is "target acquired"
[17:16:04] <Jak_o_Shadows> Does it work if you just buy the same servo, from the same aliexpress person, 20 of them, just individually so you get free shipping?
[18:01:11] <anonnumberanon> Jak_o_Shadows, do they make you pay for shipping if you buy more than one?
[18:02:34] <Jak_o_Shadows> When it's <=5, they can send it in a (free) padded envelope
[18:02:41] <Jak_o_Shadows> When it's 20, they need to send it as a parcel
[18:08:39] <psYbR> Jak_o_Shadows: buy them in lots of 4 :)
[18:09:13] <Jak_o_Shadows> haha
[18:09:17] <Jak_o_Shadows> Probably am going to

[18:39:48] * Hyratel ... wow
[19:33:29] <jhylands> my new power board arrived today:

[21:33:05] <SpeedEvil> jhylands: moar APIs are betta!
