The principle behind this scanner is the typical of a line scanner. A laser beam intercepts the object to be measured and a camera, positioned at a known angle and distance shoots a series of images. With some trigonometry considerations and optic laws it is relatively easy to reconstruct the Zeta dimension, the measurement of the distance between the object and the camera.

In this project, we’ll build a small, vertical-axis wind turbine, or VAWT for short. These are not as efficient as their horizontal-axis cousins, but they are better suited to urban environments where wind can come from all different directions. Normally, when you give electricity to a motor, it spins. The same is true in reverse: […]
