A treadmill linked to World of Warcraft

The maker connected a Xiaomi treadmill to WoW so the character can set the belt speed, or the other way round. Claude got round the addon sandbox by having the addon draw three coloured squares that a Windows app reads from the screen.

The full story

A software engineer connected their Xiaomi treadmill to World of Warcraft, so their character can set the belt speed, or the belt can set the character's pace. They used Claude for most of the work.

The hard part was that WoW addons can't talk to outside programs. Claude's answer was to have the addon draw three tiny coloured squares in a corner of the screen, which a Windows app reads to tell whether the character is walking, running or mounted. The maker calls it ridiculous, but it works, and there's a video of it running.

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.
