It looks like a homemade battery pack or adjuster for a cordless drill.

Wooden battery pack for a cordless tool. Whats in the base? AA cells?
You got it in one neophyte.
I had an an old battery pack from a dead laptop, so I made a wooden top for it to fit on an old (very old) cordless drill.

Cool, how is the laptop battery performing?
It goes really well, but this was only a very crude test. I had a really old 7.2V drill with no working battery at all. Since I was only going to throw it out anyway I figured there was nothing to lose if I had a bit of fun with it.
Though the batteries are 10.8 to 12 volts (3 by Li-Ion) and the drill is only 7.2V, it works about "normal" (not too much over done) because the batteries are pretty old and probably a bit higher resistance than they should be. I do have some actual good batteries from old laptops here if I want to do this properly at some time though. This was a "just for fun" test.

Haha, a good Christmas present for an Amish person for sure. Too bad I don't know any.
Here's the complete (very old) drill. It now works about as it did when new, but trust me that's not saying much with this **** old drill, LOL.

For fun one time, I put a long coiled cord with a cig lighter adaptor on a small 7.2 Makita. It was the best little drill for working on and in cars I have ever had. The 7.2 had tons of power running at 12volts and its small form factor (not to mention light weight) made it easy to navigate under dashes and in engine bays.
Yes, a 7.2V drill can really get going if you connect it to a good stiff 12V supply. I tested this one first up by jumping some wires to a good 12V Li-Ion pack from one of my other drills. Yeah it was really lively.
With this pack it's not quite so lively because as I say they're slightly tired old batteries that were only going to be chucked out otherwise. It does run ok though, similar to what this drill originally ran like, and the batteries seem to be holding their charge ok too. I was also able to get it to stand upright on the pack, something that the original drill never did. I tapered the top of the pack (to bring the center of gravity back), specifically to allow it to stand upright.
I'll probably keep this thing sitting around on my bench for light duty stuff now, it definitely works ok.
