I have had this idea for a while now. To build a dual arcade controller, that is powered by Raspberry Pi (RetroPie). Have searched the internet for information about it. I found several videos of this kind of builds. But the building progress i have found haven't shown all kind of information i want. I know where to buy Raspberry Pi, where to buy controllers/buttons, schetched some prototypes. The whole idea is to have the Raspberry built into the controller so i just connect power and HDMI to my tv. But none have shown a proper way to attach powerbutton to safely shut it down. You Ben is really good to explain how to do things, step by step. And may think if you make a such build, i maybe can start my own build. Have a huge interest in Raspberry since it was released, but havent all knowlegde to start with it. Here in sweden it will problably cost around 200+ euros for me to make this kind of build, but ther is maybe a lot cheapier way to do it? I have no access to 3D printer or laser cutter, or even print grafics. So my idea is a retro-looking build in complete wood if thats possible?
