This hand heater is not yet available. We’re still testing prototypes! If you’d like to be involved in the discussion about the design of the heater, please join the SuperHouse Discord server and check out the #assistive-technology channel.

Controlling an electric wheelchair can be difficult in winter, when cold hands and fingers can stop you from accurately moving the joystick. This small hand heater can be mounted on a wheelchair so that it blows warm air over the joystick area to keep your hand warm and mobile.

The example firmware provides multiple power levels, MQTT control and reporting over WiFi, over-temperature shutdown, Bluetooth control, and fan speed sensing to detect a stalled fan.
