Instructables has a great hack to turn an old Power Glove, that triumph of silliness, into an Arduino-controlled, Bluetooth-and-accelerometer-sporting modern peripheral.

With it, via I2C, I could add an Arduino Pro Mini, and an I2C Oled Display and make a watch capable of having all this information, plus a pedometer (by analysing accelerometer data).

The controller consists of a battery-powered Arduino MKR1000 with WiFi and an MPU6050 accelerometer. Held in the hand, the controller streams accelerometer data to an external PC, capturing the ...
