Have just ordered the PCB boards. Order 10 pcs, so if anyone wants one, we can sort out a price that covers the cost + shipping.

Also, order strain gauge and holders for cr2032 battery. Decided to not move anything on the PCB if I ever wanted the cr2032 on top of the board. 

The plan now is to make a small 3D printed housing for the board which will be potted and clued onto the crank arm. The cr2032 will stay in a not potted box beside, for removal. Have not decided how I will get that 100 % waterproof.
