Convert Battery-Powered Electronics To Use An AC Adaptor

We’ve reached a point where battery-powered electronics are more often annoyances than not. Charging, or even plug-in power, is so much easier to use. Instructables user DIYHacksAndHowTos shows off how to convert those battery-powered electronics to run on AC.

Although the process sounds pretty complicated, it’s not as difficult as you might think. It uses a voltage regulator circuit, a switch and a dummy battery system to take up space. The dummy battery also makes the whole thing removable, in case you want to revert back to the batteries. As with any project where you’re working with electricity, you’ll want to be careful, but the process here is pretty straightforward. Head over to Instructables for the full guide.

  • It might have been worth testing to see if the entire circuit runs in series, then you could bypass the requirement for dummy batteries… Just alligator clip the two ends.
