The full story

The Space Project is a self-running space-economy simulation in Rust and the Bevy engine, built with Claude. Nothing is scripted: a few hundred autonomous ships each run their own logic, trading, mining, hauling cargo, taking contracts and sometimes running out of fuel, and an economy emerges. It was shared on Hacker News, where it got 110 points.

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).
