The full story

The poster wanted a 3D view of their home on a wall display, where tapping a light shows what is happening in a room and controls it. Claude built most of HomeTwin, including the architecture, editor and interface, while the poster guided, reviewed and tested it in their own Home Assistant setup.

An AI feature turns an uploaded floor plan into rooms, doors and windows, which the user then checks and corrects. It is described as a public beta, MIT-licensed, with English and German interfaces. The repo includes a skill that lets Claude turn a photo and dimensions into a shared library object.

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.

Privacy. No accounts. Analytics cookies (Google Analytics) only if you accept them; no ads or cross-site tracking. Searches are counted anonymously (just the words) to show what's popular, and so are clicks on Ask Claude (just the count). The Claude connector only receives the search words your Claude sends it.
