If you’re looking for a way to build a battery-to-wall-power adapter for one of your portable devices, this tutorial can serve as a template for your DIY adventures.
Mike Worth wanted an outlet adapter for his Canon camera, but Canon wanted $75 for it. Not looking to spend that kind of cash on a very simple adapter, he set out to build his own.
The build is quite simple, consisting of a transformer with the proper voltage, and a set of dummy battery casings with thumb tacks and washers to serve as the negative and positive leads. Hit up the link below to see the full build.
