type host role blinky LED + CloudEvents vendor Raspberry Pi model Raspberry Pi Zero W year ~2017 cpu BCM2835, ARM1176 (armv6l) ram 512 MB LPDDR2 gpu Broadcom VideoCore IV os Raspberry Pi OS Lite (historical) offline hat Pimoroni Blinkt! (8-pixel APA102 LED strip) case Flirc Raspberry Pi Zero Case

Pi Zero W with a Blinkt! LED board in the Flirc Raspberry Pi Zero Case — the source of every flirc reference in the repo.
Offline (not retired — the hardware's still here, just unplugged). Never migrated into the flake; runs Raspberry Pi OS Lite with two hand-installed systemd services. The systems/rpi/blinkypi0/ provisioning artifacts lived in git until the df20515b graveyard cleanup; everything below is from that history.

cloudevents.service runs a Flask + cloudevents-python server on :3000 that turns incoming CloudEvents into Blinkt! animations, supporting blink, brighten, clear, darken, rainbow, status:

    -H "ce-id: lolpotato-123" \
    -d '{"action":"rainbow"}' \
    http://blinkypi0:3000

blinky.service runs /usr/local/bin/blinky — an 8-pixel random-colour randomizer over the Blinkt! python library (blinkt.set_pixel/show at 0.05 s cadence, brightness 0.1).
Same CloudEvents pattern as its sibling Hosts/radiopi0.

Hosts/radiopi0

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).
