“When your building and prototyping circuits , one of the most essential tools you’ll need is a variable power adapter. And if you’re going to make one you may as well use a Super Nintendo Controller to put it into!
Don’t worry, I didn’t use a genuine one, it’s a cheap knock off that you can buy on eBay for a few bucks. There were a few challengers with ensuring all of the components could fit inside the controller but with a little planning I managed to jam it all inside the controller.
I used an old 3.7v phone battery to run the power supply. These are usually easy to find (just ask around and you’re sure to find someone with a few old phones lying around) and small enough to fit inside the controller. You can also easily charge them with a cheap charging module from eBay.
So without further ado - lets get cracking”
