@NewtonMark@eigenmagic.net good luck with that, last time I checked Russia was importing their diesel to cover production shortfall and lowered their domestic production quality to Euro-3 which is causing engines to blow up

At least, Random Friend should be almost bulletproof as a dev board: ESD diodes on every header, fuses on every power input and output. It’s kinda grown legs. And arms. And bells and whistles and gongs. And tentacles.

Okay, 24V input “works” - except for the 5-24V DC input power LED circuit. Whose stupid calculations came out to a 75ohm series resistor for the Zener circuit? Yeah of course the Zener diode is going to start smoking when it tries to dissipate 1.2W of heat.
