05:02 PM SpeedEvil: 'Cameron says in the clip, referring to the time he essentially locked his team in a room with a bunch of pipes and foam core. But by the end of the day they had a recognizable prototype of the first robot exoskeleton to hit the silver screen.
08:05 PM AchiestDragon: why cant i find one of these anyware https://drive.google.com/file/d/1D92zerbq63-wltFyXIq_kU5TzP1gUXTX/view?usp=sharing they do them with power mosfets but not with signal level fets
08:20 PM AchiestDragon: ha found one a tp3350

08:20 PM AchiestDragon: tlp3350
08:26 PM AchiestDragon: well actualy no as they have a small internal circut that means it needs a voltage input of arround 20v normal so not quite good enough to use inplace of a reistor in a rc filter
08:32 PM AchiestDragon: so would still have to pwm drive the leds to get an effective change of resistance of a rc network out of it
08:33 PM Jak_o_Shadows: Is that an opto isolated variable resistor?
08:34 PM AchiestDragon: thats the idea , but opto reisitors responce to change is way too slow
10:20 PM rue_bed: oh?
10:20 PM rue_bed: I got some... H11F1? optos
10:20 PM rue_bed: led to fet
10:21 PM rue_bed: I think I got them for AGC
10:32 PM Tom_L: can you resize a linux partition without screwing up the os on it?
10:32 PM Tom_L: might try to run 2 versions
