This article shows you how to build a really cool 3D cube with a 4 x 4 x 4 monochromatic LED matrix which has a total of 64 LEDs.
This alternative energy project is two-fold. First, convert a two-cycle engine to run on pressure (air/steam). Then, create a control system to optimize engine performance. This project is very easily reproduced by any experimenter with average mechanical skills; the controller is an easy breadboard; and — best of all — it’s cheap and green!
