You’ve probably seen wireless chargers like the Powermat before, but they require you to put a big, bulky case on your phone in order to work. YouTube user tanv28 shows us how to put the necessary parts inside your phone, so you can do away with the case entirely.
It isn’t for the faint of heart, but the results are pretty incredible. You’ll need to know how to solder, and you’ll need to be comfortable opening up your phone and messing around with its insides (eep!) to get it to work. But, when you’re done, you’ll be able to just place your phone on a mat and it’ll charge the battery without any cables or extra cases.
Of course, you could probably do something similar with another Powermat-compatible phone as well — or just hack an induction charger to work with any cellphone. Check out the video above to see the full mod in action.
