Description

This was a my first attempt at designing something for production and sale. It has an ATtiny13A to drive the LEDs and has a small button on the side so that the wearer can set the energy level displayed. Powered from a CR2032 coin cell it lasts for well over a year (when the LEDs are off).

I won't need to put a battery in mine. In fact I don't need any LEDs either. 🤪
