When Ben began with the Nintendo 64 build, we knew it wasn't going to be easy! In this episode, Ben shrinks down the size of the controller, embeds the RAM expansion, and begins to design the case with design inspiration taken from the Nintendo Switch. To embed the controller we have to get creative with the notorious analogue stick. It needs to be re-worked, and thanks to an Arduino Pro Micro it can be replaced with a joystick from Sony's Playstation Vita. Further hackery comes in the form of a custom made printed circuit board to house the controller chip, as the one from the original joypad is far too big. Unfortunately, there's one final problem to overcome, you'll have to watch the episode to find out what it is! Do you have any ideas on how this portable could be made differently? Or have you made your own? Let us know on the element14 Community!
