The full story

GBody, which took third place at a Y Combinator hackathon, is an MCP server that lets Claude control a HiWonder six-axis robot arm through tool calls: move, grip, record, observe and retry. Claude is the brain and Gemini provides vision.

Rather than solving the kinematics by hand, it measures the real world: move the arm, see what happened, save the result and let the AI adjust. Built by Anish Kataria and Jake Roggenbuck.

Prompt & Solder

An independent community project. Not affiliated with Anthropic.

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).
