04:29 AM Tom_L: yup
02:27 PM polprog: rue_mohr: google youtube imgur and twitter announced deleting accounts and content for inactive users
02:27 PM polprog: imgur annouced deletion of anonymously submitted pictures
02:28 PM polprog: quite a shit show
06:20 PM rue_mohr: yea, well youtube has been out of space for years
06:21 PM rue_mohr: the rate society is burning up storage is totally unsustainable
06:21 PM rue_mohr: not many people see it.
06:21 PM rue_mohr: I had a guy at work say that we needed to keep every email ever
06:21 PM rue_mohr: junk mail and all
06:21 PM rue_mohr: always
06:21 PM rue_mohr: forever
06:22 PM rue_mohr: I couldn't help him see the light
10:18 PM rue_mohr: All 6 IGBTs are ok!!!
10:19 PM rue_mohr: I rewired the power stuff
10:19 PM rue_mohr: after the images I blew it all out too

10:20 PM rue_mohr: I still dont know the voltage rating on the caps
10:21 PM rue_mohr: well, the vfd was rated for 480V
10:21 PM rue_mohr: so the total was over 672V
10:21 PM rue_mohr: my total is 340V
10:25 PM rue_mohr: I'm looking forward to hooking up a motor and doing some speed direction abuse
10:25 PM rue_mohr: rated to 1200V,150A should mean I can do whatever I want to the drive, and if anything, the motor will explode
10:26 PM rue_mohr: the main caps are in series, so there is a balancing resistor
10:27 PM rue_mohr: I'm operating it as a voltage doubler, so it doesn't need the resistor, but it will be a good discharge resistor and will help with the overvoltage from motor braking
10:28 PM rue_mohr: Tom_L, are you sliding slowly off into the dark buddy?
