08:41 PM rue_mohr: ok, this could be interesting
08:41 PM rue_mohr: I'v not used google drive before
09:36 PM rue_bed: Tom_L, gonna rest a min, then attack the fpga stuff
09:48 PM Tom_L: never used it
10:00 PM rue_bed: I should see if I can find some junk to trim off the website too
10:00 PM rue_bed: need to rest for a min tho
10:01 PM Tom_L: opto for the motor driver?
10:02 PM rue_bed: well yes and no
10:02 PM rue_bed: I wanted to do the charge pump via opto
10:02 PM rue_bed: but then I ended up with an opto so fast, I might be able to switch the fet directly with it
10:03 PM rue_bed: I'm only using ~400hz on the motors
10:03 PM Tom_L: gonna be noisy
11:18 PM rue_shop2: yes, but I'll tune the different channels to form a C chord
11:26 PM rue_shop2: ok, thats a pretty clean slate
11:26 PM rue_shop2: (fpga stuff)
11:27 PM rue_shop2: starting with checking polarities
11:28 PM rue_shop2: tom, didn't you have a problem where a rouge character or somehting was screwing up your fpga project?
11:35 PM rue_shop2: start with the onboard leds again
11:35 PM rue_shop2: and check the polarity
11:41 PM rue_shop2: renamed the leds, 1 and 3, after their silkscreen assignments
11:42 PM rue_shop2: 1 is on
11:43 PM rue_shop2: ok, buttons evaluate to '1' when pressed
