The full story

An open-source idle virtual pet system for the ESP32-2432S028R "Cheap Yellow Display". You draw the pets yourself, give them temporary boosts with emotes and permanent ones with auras, upgrade points like an idle clicker and draw backgrounds.

Up to nine pets fit in a box, and new boxes unlock with stars earned by drawing new pets; everything saves to the SD card. The maker prompted Claude for the code.

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.
