radiopi0

type host role radio vendor Raspberry Pi model Raspberry Pi Zero W Rev 1.1 hat Pimoroni pHAT BEAT (mono 2×7 VU LED + audio DAC) case Pimoroni Pirate Radio case year ~2017 serial 0000000056f8a6ff revision 9000c1 cpu BCM2835, ARM1176 (1c, armv6l) ram 512 MB LPDDR2 (package-on-package) gpu Broadcom VideoCore IV storage 32 GB microSD (root 30 GB, 8% used) os Raspbian 10 (buster)

  • Pi Zero W radio box in a Pimoroni Pirate Radio case with a pHAT BEAT DAC + mono VU LED bar. Unmanaged: not in flake.nix, runs EOL Raspbian buster, login is pi@radiopi0.lolwtf.ca.

  • radio.service runs /usr/local/bin/radio, an HSV rainbow chase across the pHAT BEAT's two 7-pixel channels (phatbeat.set_pixel/show at 1 ms cadence). Its CloudEvents sibling lives at Hosts/blinkypi0 (ce-type: dev.pulsifer.radio.request, also on :3000).

  • Scrape target for folly's node-exporter job (clusters/folly/monitoring/...; instance: radiopi0 → radiopi0.lolwtf.ca:9100).

  • Candidate for adoption into the flake (armv6l makes NixOS awkward — cross-compiled or stay Raspbian).

  • See Fleet for the full inventory.
