That's a really good idea. I'll just need to find an IT help desk.I think Larry's onto something there. Ask someone in the IT helpdesk field if they have any old battery packs you can have. At the very least, you'll end up with a handfull of cells that, while used, have all been used at about the same rate and amount. To them, it's trash because the computer won't use it. Usually that means they are at maybe 70-80% of their original capacity at the currents that the computer would be drawing from them. To us, it's more than capable of loading a single diode and its supporting components, and I'd imagine your use would be just as "light" a load on the cells as our lasers and such.
Not to mention the tabs are already welded into usually 3s2p configuration, meaning fewer connections for you to make.
I wonder if it would be evil to just figure out which stores do laptop battery pack recycling, and see about grabbing some of those? In some cases, they just have giant cardboard drop boxes at the front of the store. I could ask permission. But either way, I'm sure that the way I would be recycling these cells is at least as, if not more, environmentally friendly.
