If you have a video game controller that's worn down so much that the buttons barely work, you can give it new life with a few small pieces of aluminium foil. All you need to pull this off is a torx scredriver (something every techie should have on hand), a hole puncher, and a bit of glue or tape.
Basically, you'll be placing the aluminium foil on top of the worn down rubber pads, giving them a bit more strength (not unlike our previous tip about using an orange juice carton to fix your spacebar). This should work for more than just video game controllers too. It can also help TV remotes, or anything else that has a similar kind of button. Hit the link to see the full how-to.
