LEDs have survived evolution. Once expensive and emitting low light, today they can successfully replace bulbs. However, the control of high power diodes requires the use of a suitable voltage source. The main point is not to exceed a certain current value. Overloaded LED power diodes quickly deteriorate their parameters. Of course, ready-made drivers for such elements are available on the market. We propose a self made power supply for 'power' LED diodes. It has two advantages - the use of popular, often losing parts in the drawers, and the unsatisfying satisfaction with something that has been built by itself.

The device is especially recommended for lovers of light effects and experimenters
