interesting thread... the strain gauge in combination with arduino pro micro and a bluetooth module is very intersting. The Arduino Micro has differential ADCs, so i guess the signals of the strain gauges could be measured quite accurate. Bluetooth module and arduino micro are so small they fit on the crank easily. Two 18650 batteries fit into the hollowtech2 shaft, they can power the Arduino directly without the need of an additional voltage converter.
