Variable USB Power Supply (5V 2A)
Is there a simple way to put together something that is protected (so I don't kill the USB socket I get power from) and has a Variable Volt and Amp adjustments knobs/buttons. I've looked at getting a full size Bench Power Supply, but would love to just have one so that I can power from my laptop or any of my million Micro USB power adapters (5v 500ma through 5v 3A supplies). My first project is something I need to eventually run off of AA batteries, but I didn't wanna keep on re-charging the batteries while I test my circuit design. Would rather have a constant source of 1.25v-1.5v power during the prototype phase.
I'm just now getting into Electronics, so please take it easy on my poor little brain.
Hopefully this hasn't already been asked, didn't find anything in my quick search through the forums.
