Homemade g force meter, Jesper writes – “This is a fun project. Unfortunately, it takes some time to develop the code, so this is a work in progress and here i’ll just present the project so far. Basically the AccelR8 is a device for measuring acceleration. It can measure +/- 2 g. As it contains a microprocessor, it an also measure time. This opens up some interesting possibilities. If we have the acceleration and the time, we can find speed (V), as V = a * t.” [via] Link.
