If you have a device that doesn’t come with a wall-adapter, this tutorial outlines how you can construct your own using generic parts and, in the process, free yourself from dependency on fickle batteries.
Instructables user Txoof was irritated by the lack of official wall adapter for his Olympus E-510. Rather than bemoan the inability to run off the steady supply of energy access to the wall current provides, he constructed a false battery which provides power to the camera via a wall charger. It’s not a hack for those new to working with electricity and DIY electronics projects but it is an effective and inexpensive hack for devices painfully lacking in adapters.
