Do not throw away the old cartridge - make it a bank
Thinking about another home-made product, I realized that there is no strong Powerbank. Immediately formed the idea of a design in a pipe. But I didn't want to take PVC pipe. To solder it is not a problem, but somehow handicraft. As always, the old cartridge from a laser printer came across. The cartridge has a photo drum. It is painted, has a sturdy construction, is light. The drum inside is hollow. In the case of his perfect pair. We decided to do a photo drum in the case.In general, we extract the photo drum and the cartridge. Everything is simple, you need to unscrew a pair of screws on both sides of the cartridge. Left only the drum and screws, threw the rest.Already a lot of toner flies in all directions.The drum is cleaned from the toner, the case is not scratched, excellent. With the help of a heat gun I extract the guides. They are made of plastic, they go out well from the case. For the Powerbank design I use two batteries with residual capacity as in the photo. For my ASUS android background, I missed one and a half times.
Make a Powerbank from a printer cartridgeGet a cartridge. If it has a lot of toner, then clear. I had it old and the toner was a little bit. But this did not stop me from getting dirty.
BuildSolder the batteries by cons to each other. To the junction of solder wire. We do the same with the plus. Since the batteries are used, then when disassembling, I recommend not to tear off the nickel-plated tape, but to cut it off. It's easier then to solder the wires to it. I have one minus pulled away, I had to carefully solder. We draw wires in one direction, there will be a charge controller.
