Worked Proof shown

Air-traffic recordings turned into Final Approach Radio

The maker used an RTL-SDR to record Chicago airport radio, then used Claude Code for much of the editing behind a lo-fi listening site.

The full story

Final Approach Radio layers recorded air-traffic-control audio over lo-fi music. Its maker collected recordings at three Chicago airports using a magnetic-mount antenna, an airband filter, an RTL-SDR and SDR++. The site lets listeners adjust the balance between radio and music.

The launch post credits Claude Code with much of the editing. The recordings replace the live feeds used by an earlier service, so this version is not a live air-traffic feed. The author reports using it as background listening for about two months before sharing the launch.

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.
