The full story

Jason Welsh runs Claude Code on a Raspberry Pi and reaches it from an Android phone over SSH, using a Linux environment in Termux. From the phone he can have Claude write and flash code for ESP32 and Arduino boards plugged into the Pi.

With a battery pack and the phone's hotspot, it becomes a portable, even off-grid, programming station.

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).
