Introduction: 3 Output Power Supply

Picture of 3 Output Power Supply

I needed an external power supply for my projects. I had an old dvd player which refused to work anymore so I decided to give him another utility. I have removed the power board and all other parts which could be used for some other projects.

With power supply from dvd player I made one external power supply for my projects which has three outputs: 1 x 12V, 2 x 5V and 2 x GND.

WARNING: WATCH YOUR FINGERS FOR HIGH VOLTAGE - 110/220V !!!!!
