The full story

A Reddit user used Claude Code to search public telescope data and flagged what they believe is a planet no one had catalogued. The Hacker News link drew 302 points. Commenters asked why automated searches hadn't already found it, and pointed out that NASA's TESS and ESA's CHEOPS missions run citizen-science projects on Zooniverse for exactly this kind of hunt, where finds can be checked by others.

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.

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.
