Neat battery hack.

Hey guy's, I was at a diy website (kipkay.com) and found this video:

Really cool, my question is, what are its potentials if any?

Well, with a quick search on Youtube, it seems like it's pretty popular to *implant* one of these things into your fingertips. Why? I have no idea, I guess because it looks cool when you can pick up stuff without touching it. Is neodymium dangerous? And the better question, who told people to stick these things inside your body?

edit: just realized the magnet wasn't actually in the lantern battery. not sure what i was thinking, must be going nuts from too much ats.

No idea what your talking about, nothing about sticking magnets in your body from the link i provided...

I did a search on youtube for neodymium magnets, and that was what came up. The device they created on that video is a homopolar motor. It can basically be used as a way to transfer electromagnetic energy into mechanical energy. I doubt there is much power in the F cells to really do much, though with some ingenuity you might be able to use it in a toy robot or something.

The concept is intriguing though. If it were to be applied on a bigger scale, then it could power some bigger machines maybe. It's the same concept as a faraday disk.

that was a cool hack, i like this guys hack. So what is the reason this hack only works with these kinds of batteries?

This tutorial has only been tested with that brand, others have other methods of battery packaging.

You can make a homopolar motor using many differnt kinds of batteries. Here's a video that shows how to make one with a simple AA battery:

And here's a guy who had some fun making a variable-speed hmopolar motor (again using a AA Battery):

Here's a "how-to" article:

I laugh at you primitive battery hack and blow you away with my super amazing VCR hack.
Bet you didnt know all this stuff was just waiting to be plundered inside your old video recorder

It is pretty much a given that any chemical cell arrangement that puts out more than 1.2-3 volts is actually several cells. In this case, the 'standard' for a 6-volt lantern battery is and has pretty much always been 4 'F' cells inside a squarish box. Likewise, the little 9-volt batteries are made of 6 'AAAA' cells inside a rectangular box.

Possibilities? Well, I suppose if you were building something that used 1.5 volts (the average cell voltage for alkaline cells) but needed a tremendous amount of current, you could rip a 6-volt battery open and re-wire it into parallel.... but you could also just buy 'F' cells easier (one link to a rechargeable order page - Note! I do not know this supplier!). That's about the only possibility I see for it, other than an interesting look inside how things we tend to take for granted are made.
