Five-cent Tilt Sensor - More DIY How To Projects]]> http://img.instructables.com/files/deriv/FTO/YJIE/FQCTL721/FTOYJIEFQCTL721.SQUARE2.jpg http://img.instructables.com/files/deriv/FTO/YJIE/FQCTL721/FTOYJIEFQCTL721.SQUARE.jpg http://img.instructables.com/files/deriv/FTO/YJIE/FQCTL721/FTOYJIEFQCTL721.SMALL.jpg ix This is a basic tilt sensor inspired by ball-and-cage style sensors, but 2d instead of 3d. A captured nickle connects pairs of wires depending on the sensor orientation. These are quick to build, and pretty cheap; I came up with them for a project where I wanted to know which face of a cube was poin...

This came out of a need for the MATE ROV Competition. The LM35 series are precision integrated-circuit temperature sensors, whose output voltage is linearly proportional to the C...

The measuring device for rotational speed is a tachometer. But they are expensive and not easy to find. Its cheap and easy to make one using a bicycle speedometer (cyclocomputer). In fact, the only thing you need is a ...
