Build Fake Batteries to Run Electronics On AC Power

Build Fake Batteries to Run Electronics On AC Power

If you have any gadgets that only use batteries, and don't accept AC power, you can convert them to run on the grid by building a fake battery pack and hooking it up to a power adapter.

Jason Poel Smith wanted to run his electronic baby swing off a wall outlet, but it lacked a standard barrel jack. This hack isn't for the faint of heart, so if you aren't comfortable with electronics, it might be better to sit this one out. Basically you'll need to convert an off-the-shelf power adapter to wire directly into the fake battery pack, which will involve soldering on resistors to match your target voltage. Once your power supply is ready, you can cut your fake batteries out of dowel rods, then add some screws to each end to act as the contacts. Finally, wire up the screws to your power supply, and pop the battery pack into your desired gadget. For complete instructions (you'll need them), check out the source link.
