The Underwater Robot
This is my underwater robot, modeled after the designs found at openrov.com. It is extremely cool, and actually does work, believe it or not. It uses a Raspberry Pi and Arduino for the brains.
The Mars Rover
This is my lame attempt at making a Mars rover-style robot. It is controllable via Wi-Fi, and sends a camera feed back to you so you can go anywhere with it, as long as you're within range. It goes a lot faster than Curiosity, but it's a lot uglier too. It uses the same electronics chain as the underwater robot, with a Raspberry Pi and Arduino.
The Arcade Box
This is a Raspberry Pi-powered arcade box, which I and my sister made. It uses the RetroPie software. Yes, I know this is a terrible picture. Too bad.
