The full story

Craig Hollabaugh had Claude Fable 5 drive Blender over MCP and, in one morning, build a live simulation of a 6AU6 pentode valve amplifier. It models electrons as particles, solves the load lines and shows the result on a working on-screen oscilloscope. A 6SN7 triode version followed. The Blender files and code are on GitHub under the MIT licence.

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.
