It seems like everyone aspires to make their own little retro game console with a Raspberry Pi, but one of the hurdles in doing so is wiring up your own joystick. To fix that, Adafruit created the $US15 ($19) Arcade Bonnet.
'.Since it was released, the Raspberry Pi has been hailed as the perfect all-in-one retro game console. Now, it's easier to do than ever, and it doesn't take any advanced Linux knowledge to do. Here's how to make your own retro game console in about 30 minutes..'
The Arcade Bonnet is about the same size as a Raspberry Pi Zero and makes it so you can easily connect up to six arcade buttons, a joystick, and speakers. Essentially, you just put the Bonnet on top of the Pi's GPIO, connect your buttons and joystick, and you're ready to go, no complicated soldering required aside from the GPIO. If you've been itching to make your own little arcade console, this should make that process a tad be easier.
