Goddamnit I am an idiot. I just fried a microcontroller because I didnt have the right power supply and I used it anyway because fuck it, right? So now I am not a single step closer to the thing I was trying to do but I fucked up my hardware and it is a huge pain in the ass until I get a new one and figure out all the problems with it. Arghn

    I fried a voltage booster while testing nixie tubes. Connected the booster to the lab psu with wrong polarity 🤦‍♂️

    That's where the trick with the two anti-serial Z diodes and the melting fuse would have been handy.

    @Fast-Nop meh, who needs standard fuses when you can just use a Raspberry Pi as a fuse instead! It doesn't just melt, it burns, with delightful smoke from a cracked SoC providing ample and timely indication of overload!

    Personal experience :/
