From time to time I could really use a battery eliminator.
It’s not a term that’s solidified into this precise definition, but it’s often referred to a combination AC->DC adapter connected to something that looks like a battery that then is plugged into the battery slot of a device.
I’ve found some expensive ones, mostly of the wrong voltage, but two questions:
Is there a good place to get such things inexpensively? What is your favorite all-kinds-of-electronics store?
I’ve seen some suggestions on building one of your own. Usually involving a wooden dowel, a couple of nails, and a wire connection to each to a socket for an AC->DC adapter.
Any thoughts? Have you guys bought/made something like this before?
