An old Xiaomi phone turned into an offline MP3 player

Claude stripped a laggy LineageOS Xiaomi phone down into an offline MP3 player that takes music from a laptop.

The full story

The phone was laggy even with LineageOS and already had a launcher and most apps removed. The poster asked Claude to strip almost everything and make it a flashy MP3 player that a laptop can connect to for transferring music. They were inspired by a smart TV post.

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.
