This project is based on fahrradlader.de v2 with added Schmidt-Trigger, MCU, NFC-antenna and current measurement. There even is a SSD1306 OLED-Display with one button control.

I do not own original fahrradlader v2 (but have bought v3 as a bday gift). I can recommend the dev :) I was missing an MCU for current control and a Schmidt trigger to use hub dynamo as sensor.

This project is done: PCB is populated and tested, works and is documented.
#TODO: insert documentation.
#TODO: finally add NFC.
