WEMOS mini's are such a timesaver - or am i doing this wrong?
summary
Uses cheap WEMOS Mini boards and Aliexpress shields to build distributed props that actually run reliably for months: six Raspberry Pis plus many WEMOSes drive neopixels, UHF RFID, NFC, buttons, motors and servos, orchestrated via MQTT + simple JSON events and Node-RED to trigger DMX and audio. Projects include a Museum of Brisbane install running four months and multiple festival shows; buys 30–40 units at ~$5 each; common failure is power draw — 32 neopixels cause CPU browning unless powered separately, but overall the over‑provisioned approach works.
