Dispenser (with Live Treats!) on Raspberry Pi 5
summary
A Flutter app running on Raspberry Pi 5 drives a 10" IPS display, 3D‑printed mounts and continuous‑rotation servos through a PCA9685 I²C servo board that can control up to 16 channels; servo control lives in a Python D‑Bus service so Flutter talks to it via the canonical debus package. Development uses a desktop CLI that sets up passwordless SSH and exposes remote hot‑reload and debugging. Claim: the visual Flutter UI performs very well on 4GB and the dispenser demonstrably works with live streams.
