my first impresion was that the nrf could fit nicely in the ps3 case, except maybe for the header pins (spoiler i was wrong) and o little hole in the back of the controll for the external antenna

it didn't fit as expected, there was a little tap on the controller that didn't allow me to get to the bottom, so i had to use my dremel to do the job, and finally the hole that i thought would be a small one turn out to be huge.

and i used and arduino nano because, the control already has a mini b connector hole, so it makes it easier to put the arduino inside
