Board and LED. This is bright enought to illuminate my desk at ca. 30mA, does not even get hot.

Testing the video LED driver for the mechanical TV, gain and pedestal adjust work wery well too.

I just blew it up because the 12 supply touched the GPIO pin, awesome.

PWM value change every 100ms in one of the threads (~85% cpu usage, Raspi model B+ v1.2)

Hell's freezing over, this is multithreaded GPIO in pure python 3.

The EGT indicator toots were repated bc i didnt notice that the crossposter to bird site was not enabled for masto replies. So the tweets i made manually got reposted on masto lol

The display is liquid crystal! Theres space for 3 digits in the middle, it has a blue backlight (4 leds). EGT = exhaust gas temperature?

omg. It's actually a liquid crystal display, with an octagonal zebra strip connector and 4 blue LEDs for backlight :o I think there is space for 3 digits in the middle. The pogo pins go to the substrate

Theres an 87C51 on it, im going to try and take the display head apart. theres only 10 wires going into it.

It's a specialized tool meant for power analysis of smart cards. A very demanding project, USB comms next to a very noise-sensitive analog frontend. Im curcious to see how the new revision performs.

I've been assembling the third revision of this recently, perhaps it will be ready on sunday. Stay tuned.
