Power Supply

Instead of using wall transformers to power my equipment, I decided to see if I could easily build a variable power supply. This way I can add the same connectors to the hardware and use them with the same power supply. I had an old power adapter from a HP printer laying around. I like to try and use old hardware to build new things. It gives off 19 volts and 7.1 amps. So I started looking for a way to control/vary the power coming from the adapter.So I picked up this DC DC Buck Converter CC CV 50V 5A Power Module.

Now I don't have to have all these different wall transformers taking up space. I intend to either build a box from some plastic I have laying around or maybe 3D print the case. I will come back to it when it is done.
