This project is a "lightweight" version of the data capture device. It does not store information.
This unit measures the acceleration and deceleration of the boat as it is being rowed. This data is used to calculate the rating (number of strokes per minute) and the amount of power being generated by the crew. These are displayed in real time.
Two of the images above were taken when I first made the device. You can see from the third that this unit has been out rowing with me many times.
The processor is an ATmega, and the code was developed using the Arduino programming environment.
