The full story

A hobbyist's robot, which uses Claude Haiku as its language model, recognised itself when shown a mirror. The maker says its response was unscripted and that it was never trained on its own appearance; the model simply knows it is a robot.

The maker described being "both amazed and unsettled" by the result. The post does not say how the robot was built.

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).
