[04:17:22] <rue_shop3> @#%#$&@#$%$%&!#!$%
[04:17:29] <rue_shop3> pwm chip, tlc5940
[04:17:45] <rue_shop3> same avr, same tlc5940, but on breadboard, works fine
[04:17:55] <rue_shop3> on veroboard, dosn't work
[04:18:00] <rue_shop3> W. T. F.
[04:27:28] <rue_shop3> ARG
[04:35:04] <mrdata> different parasitics
[04:35:27] <Jak_o_Shadows1> magic
[04:42:18] <mrdata> check critical places for things like ringing
[04:42:37] <mrdata> i found +2dB ringing on Vcc on a board, oncew
[04:43:00] <mrdata> and added a small RC filter and everything worked after that
[04:45:49] <mrdata> that and of course check all solder connections and verify the circuit
[04:46:15] <mrdata> rue_shop3, is there any way to debug it in stages?
[04:53:10] <rue_shop3> I forgot the output current set resistor
[04:53:24] <rue_shop3> the voltage on the pin looked right, so I didn't check more
[04:53:51] <rue_shop3> that resistor took me like 2 months and 8 hours
[05:07:19] <rue_shop3> well god, getting that working is such an accomplishment, that even tho its only 2:30am, I'm feeling like I'll call it a night
[09:51:34] <branjb> finally got an led pulsing on an stm32, haha
[10:11:57] <deshipu> woo
[10:25:04] <branjb> it was sneaky, stm's have a timer out, and a complimentary timer out that is the inverse of timer out. took me awhile to realize you have to enable the timer out complimentary in addition to the regular timer out
[11:32:40] <anniepoo_> groan.... yes, I went through the same thing
[11:39:42] <z64555> .log
[11:39:55] <z64555> no, that's not it
[11:39:58] <z64555> .zlog
[11:40:05] * z64555 grumbles
[11:41:17] <z64555> zlog
[12:09:26] <Tom_L> jeeze
[12:09:41] <Tom_L> he has a name :)
[12:20:32] <z64555> the other bot's I'm used to have an escape character before the command
[12:20:43] <z64555> this one seems to just look for its name, zlog
[13:37:15] <rue_house> so, I got a quad copter price at the christmas party last night
[13:39:56] <deshipu> it's spelled "prize"
[13:40:40] <rue_house> thanks
[13:41:13] <rue_house> do you know if there is a plugin for halting javascripts in firefox?
[14:01:22] <SpeedEvil> you can turn them off
[14:01:30] <SpeedEvil> I suspect that's not what you want though
[14:06:19] <rue_house> no , they have had their execution time, I want them all to stop now
[14:08:32] <branjb> just finished my term project, had to implement a MIPS pipelined datapath in verilog. feel so accomplished that it works
[14:15:50] <robopal> congratulations
[15:13:51] <justanotheruser> where can I find a nema34 mounting hub? I want to mount my motor to my axle
[15:14:41] <rue_house> hub?
[15:15:19] <justanotheruser> maybe theres a word for that
[15:15:25] <rue_house> bracket?
[15:15:34] <justanotheruser> no?
[15:15:39] <rue_house> the motor has a flange on it..
[15:15:42] <justanotheruser> how would a bracket help me mount my motor to my axle
[15:15:47] <rue_house> you want to attach to the shaft?
[15:15:52] <justanotheruser> yes
[15:15:55] <rue_house> a shaft coupler?
[15:16:03] <rue_house> nothing do to with nema34 then
[15:16:19] <rue_house> you just need to know the sizes of the two shafts and get a coupler
[15:16:24] <justanotheruser> oh, sorry, I thought the nema standard specified the shaft
[15:16:28] <justanotheruser> as well as the body
[15:16:38] <rue_house> no, just eth body
[15:16:53] <rue_house> https://www.aliexpress.com/wholesale?catId=0&initiative_id=SB_20161204124815&SearchText=3x4+shaft+couple
[15:16:58] <rue_house> 3mm to 4mm shaft couplers
[15:17:04] <justanotheruser> mhm
[15:17:09] <rue_house> if your sharp, youll get the idea how to search for what you need
[15:17:20] <rue_house> china dosn't do antiquated imperial sizes
[15:17:32] <justanotheruser> can should I get a keyed axle as well?
[15:17:51] <rue_house> you also need a shaft to couple the motor to?
[15:18:01] <justanotheruser> yes, I am still deciding that
[15:19:13] <rue_house> http://ruemohr.org/~ircjunk/tutorials/mech/EMTchart.html
[15:19:50] <rue_house> 3/4" EMT will only twist .09 degrees per meter of length per N*m of torque
[15:21:11] <justanotheruser> why are all of these missing torque deflection
[15:21:20] <rue_house> I didn't measure it yet
[15:21:30] <justanotheruser> oh its your site
[15:21:36] <justanotheruser> I don't think EMT is acceptable
[15:21:41] <justanotheruser> I will probably use steel
[15:22:21] <rue_house> what grade of steel?
[15:22:41] <rue_house> 316 is good and noodlie
[15:22:52] <rue_house> till it workhardens anyhow
[15:22:58] <rue_house> then its brittle
[15:23:00] <justanotheruser> what is the difference between an axle and a rotary shaft
[15:23:21] <rue_house> politics
[15:23:33] <rue_house> your boss wont let you buy any more axles
[15:23:37] <justanotheruser> which one should I get if I voted trump
[15:24:00] <justanotheruser> why would my boss care how many I buy
[15:24:20] <rue_house> if a person had to vote for kang or kodos, would you hold it against them for which one they voted for?
[15:24:42] <justanotheruser> yes
[15:24:50] <rue_house> but its a two party system :)
[15:25:08] <justanotheruser> why are keyed motors convex and keyed shafts are concave
[15:25:20] <rue_house> 'or you COULD just throw away your vote'
[15:25:47] <rue_house> hu? all keyways should be square
[15:26:07] <justanotheruser> actually just found one that is convex
[15:26:22] <rue_house> oooh wait, there is a 3rd dimention
[15:26:26] <rue_house> for D keys
[15:26:58] <justanotheruser> https://www.aliexpress.com/item-img/Nema34-Planetary-Reduction-Ratio-1-16-planet-gearbox-86mm-motor-speed-reducer-high-accuracy-type-6/32763245555.html#
[15:28:07] <justanotheruser> how do you catalogue parts? Spreadsheet?
[15:29:09] <rue_house> I dont, cataloging parts is stupid overhead thats pointless
[15:29:14] <justanotheruser> oh
[15:29:19] <rue_house> I build things, I dont correct inventories
[15:29:24] <rue_house> constantly
[15:29:33] <justanotheruser> but what if you need the exact same part to replace
[15:29:44] <justanotheruser> wouldn't the catalogue make it easier?
[15:29:49] <rue_house> it looks like convex/concave MIGHT be reffering to what side of a 'pipe' the keyway is on
[15:29:57] <rue_house> I have drawrs
[15:32:14] <justanotheruser> how is carbon steels torque deflection?
[15:32:20] <justanotheruser> looking at these

[15:33:38] <rue_shop3> briwser being slow, cant find iamges of parts wall
[17:15:33] <rue_shop3> ok
[17:15:35] <rue_shop3> so
[17:15:41] <rue_shop3> the pwm chip is working
[17:15:50] <rue_shop3> so, next I might as well set up some of the motor drivers
[17:15:56] <rue_shop3> 1 or 2 channels
