@avanc
Just want to share my idea, what I gonna do with the Puck when it arrives:
Last week, I bought my new bike. Normally, I don't need a tachometer. But I'm still interested, how much kilometres I have ridden the past year.
So my idea is to connect the Puck to a reed contact and count the wheel ticks. If needed, I can use my smartphone to read out the kilometres.
