Many times while traveling, I have had the need to debug my firmware on a circuit board. Unfortunately, I was not carrying a power supply. So in turn, I had to wait until I reached my lab before I could power my circuit board to test the new firmware. This new innovative project, the USB Based Variable Power Supply, will solve this issue effectively, affordably, and reliably.
A quality power supply is crucial for anyone who is into computer engineering but most variable power supplies are AC/DC, which are large and very inconvenient to carry while traveling.
VariPower-USB-500A is open source hardware. All hardware design files and firmware source code are released under the GPL v2 license. It’s a great way to get started with electronics!
