The full story

Reginald is an ESP32-S3 that fetches the latest Toronto Blue Jays game from MLB's public stats API and shows it on a 2-inch colour screen.

The live game feed can exceed 1 MB, and streaming parsing was too awkward, so the maker chose an ESP32-S3 Supermini board with 2 MB of PSRAM to hold it whole. They warn it may crash if a long game makes the feed too big. It builds with pioarduino, a PlatformIO fork, and points at a local time server that others should change.

The code is part of a larger device with buttons, a light sensor and a speaker, released on its own for anyone who just wants the scoreboard.

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).
