Mini Ms. Pacman

The bragging rights of owning a vintage arcade machine are awesome, but the practicality of it – restoring what is likely a very abused machine, and the sheer physical space one requires – doesn’t appeal to a lot of people. [Jason] has a much better solution to anyone who wants a vintage arcade machine, but doesn’t want the buyer’s remorse that comes with the phrase, “now where do we put it?” It’s a miniaturized Ms. Pacman, mostly scale in every detail.
The cabinet is constructed out of 1/8″ plywood, decorated with printed out graphics properly scaled down from the full-size machine. Inside is a BeagleBone Black with a 4.3″ touchscreen, USB speakers, and a battery-backed power supply.
The control system is rather interesting. Although [Jason] is using an analog joystick, the resistive touch screen monopolizes the ADC on the BeagleBone. The solution to this problem would be to write a driver, or if you’re [Jason], crack the joystick open and scratch away the resistive contact until you have a digital joystick. A nice solution, considering Ms. Pacman doesn’t use an analog joystick anyway.
