Claude said there should be voltage across two wires; the multimeter read 0 V; the maker plugged it in anyway and the ESP32 died.

What went wrong

The lesson

When the model and the multimeter disagree, believe the multimeter. Claude can't see your wiring; check the pinout and voltages yourself before power goes on.

The full story

Claude said there should be voltage across two wires. The multimeter read 0 V. Assuming they'd measured it wrong, the maker plugged it in anyway, and the ESP32 died.

What this is. Real projects where people used Claude to build, fix, port, revive or take apart something, from jailbroken Kindles to rebuilt DOS games, plus the times it went badly wrong. Every build links to where it was shared, and every source is listed here.

How far to trust it. We summarise what people reported and say what each build rests on: a full write-up with code, a short post, or a passing comment. We haven't tested them ourselves. Photos are shown from the original sources with credit. Only modify hardware you own, and back up first.
