Shame you don't have a hub dynamo. If you did go the nRF5x route, you can lose the AVR, as the nRF5x is more than capable of handling the other tasks(i.e. reading the accel,...

Hi side FET switch for low voltage
Thanks. Thinking about it, I probably don't need the NPN to drive it, I can use just use a GPIO pin, set as input with pullup for OFF, and low output for on. As contrary to the...
