A Dynomometer measures actual horsepower and torque output at the wheels of a vehicle. Aside from racing, it's long been the way to test out engine modifications. [Steve] built his own. It uses a Basic stamp for data aquistion, and a custom machined drum for the physical interface.

自制功率计
功率计可以在车辆的车轮处测量实际输出的马力和扭距。除了用于赛车外，它一直被用来测试改装的引擎。 参见：史蒂夫的网页built his own. 该功率计使用名为“baisc stmap”的微控器来收集数据（网址： data aquistion）， 通过把车轮放在一个定作的圆鼓上来进行测量（网址：custom machined drum）。
