“A variable DC power supply is really useful to keep on your desk for charging your phone, plugging in a raspberry pi or any other low voltage electronic devices. By using voltage regulators you can set just the amounts to output, whether you need 3.3, 5, 12 or any other amount. This is a really fun project that you can customize to your needs, varying the amount of plugs, set the voltage, choose the size etc… I used MDF for the build, however you could make a box out of anything really to house the electronics.”
