batteries

In case those controllers you just got need a little fix.

There's more Christmas fun like this right over here!

Submitter ariled says their kitchen scale's button cell ran out of power and they didn't have another one. Luckily they had two AA batteries, some wire, and duct tape.

Submitter gsimon was in a hotel room with no phone charger. A data cable, a paper clip, a key, and the batteries from the keyboard of the set-top box combined to make a fine substitute.

The revolutionary technology behind 3D-printed car parts, food and guns can also be used to print batteries smaller than a grain of sand. Scientists have used a 3D printer to make linthium-ion microbatteries that can fit into tiny devices that had previously stumped engineers looking to power them for longer periods. The batteries were constructed from interlaced stacks of tiny battery electrodes, which conduct electricity, that are each smaller than the width of a single human hair.

So one of my friends gave me an iPod touch that needed a new battery. But I didn't want to pay about $15.00 for a new one, considering that I could screw the thing up trying to solder it in. So I got the crazy idea to modify and use the working battery from my old cellphone. But it didn't fit inside the case because it was too thick. So I successfully connected it to the old battery's controller circuit and hooked up the "new" battery. I had to glue it to the outside of the case. Now, everybody wonders what that big black thing is on the back of the ipod. But hey, it works and charges just fine!
