Flow-time Flag
thingiverse
This custom enclosure is built for NodeMCU ESP8266-powered IoT devices that you can attach to your monitor to signal to colleagues not to disturb you, as you're deeply in flow state. This enclosure is designed to snugly fit a NodeMCU ESP8266 microcontroller board and an SG90 servo motor. The rod mount accommodates a 3mm diameter rod used as a flagpole; I purchased my wooden rod at the local DIY store.
