Six bash scripts, a $10 Pi, and a personal FM station

Trwmato's Pi-FM-Kitchen-Radio turns a Raspberry Pi Zero W and a $10 car Bluetooth FM transmitter into a 24/7 personal radio station — no soldering, no PCB, no GPIO. Six shell scripts handle playlist generation, RSS podcast downloading, content rotation, and Bluetooth routing, all managed by a systemd service that starts on boot. Full BOM is $30–50; build time is 2–4 hours. The project hit 550 Reddit upvotes and 148 Hacker News points within three weeks of its original post.

CP/M on an 8-pin chip for $26 — meet the MCL8080+

Ted Fried's MCL8080+ squeezes a complete Intel 8080 emulator into an ATtiny85 (8 pins, 512 bytes of RAM) by offloading memory, storage, and I/O to a Teensy 4.0 over SPI, then adds a 128-byte direct-mapped cache inside the ATtiny85 to make it fast enough to boot CP/M at near-Altair 8800 speed. The full build — schematics, KiCad PCB, Gerbers, and both firmware files — is MIT-licensed on GitHub. BOM totals ~$26–30, all through-hole, Intermediate difficulty.
