You could either use Raspberry Pi to build an auto-tracking sentry gun turret, or to transform a Retro Pixel Art Game Bluetooth speaker into a functional mini PC like Carter Hud did. First, the internal speaker and electronics had to be removed before a USB Blackberry keyboard could be installed, complete with a custom bezel.

Next, Carter had to find a 4-inch LCD screen that was designed specifically for use with Raspberry Pi boards, but unfortunately, it wasn’t designed to fit inside a Retro Pixel Art Game Bluetooth speaker case. So, the corners of the screen had to be trimmed and then a new display bezel had to be 3d-printed. For those interested in attempting this project, a Raspberry Pi Zero board is recommended over a full-sized model.
