The full story

A compact desk clock on a small round display. It has several faces you can swipe through, swaps faces automatically every few hours, and some faces show local weather; first setup opens a captive Wi-Fi network for NTP time sync and a weather zip code.

It runs on an ESP32-S3, C3 or C6 with a cheap 1.28" LCD or a Waveshare C6 OLED unit, and the maker tested all combinations. They say it was "pretty much all done with Claude".

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). The Claude connector only receives the search words your Claude sends it.
