Fake-Battery (AA / Mignon)

thingiverse

I'm a bit concerned about some battery-powered devices that are so poorly designed they continue to consume power even when switched off. This can be particularly frustrating if these devices are only occasionally used, as the batteries tend to drain quickly and may not have enough juice left when you need them most. One solution is to remove the batteries after each use and store them separately from the device, but let's face it, that's not always a practical option. It requires some discipline to remember to do so every time, and storing the batteries externally can be a real pain. This adapter eliminates those issues altogether. As long as you've got power coming in from the wall socket, your device is good to go at all times. And I'll let you in on a little secret - when building this thing, I opted for bare silver wire with a 0.6mm diameter for the battery contacts.
