I’ve created a smaller version of the modular gearbox. This is a 4 speed design which is the same size as two modules from the first Modular Pneumatic Gearbox.

Modular Pneumatic Gearbox
This is the gearbox I designed for my upcoming supercar. It shifts gears by lifting and lowering entire gear racks. This minimizes spinning dead gears. Shifting is done using pneumatic cylinders connected to a compressor. The design is modular; it is easy to add an extra speed to the gearbox or swap gear ratios.
It would also be possible to use (mini)LA’s or small pneumatic cylinders. A design with the bottoms of the modules fixed together would also be possible
If there is enough demand for it I will make instructions or demonstrate different setups.
Minipult: Lego catapult controlling a video game
This is a catapult I made to control the Digipult video game that was made by me and two other guys from my college. The catapult is built on top of an old PS/2 mouse. I have attached rubber bands to the encoder wheels of the mouse so the gears can control it. The video game is about destroying a castle by shooting at the screen. The goal is to free Maria’s lover prince Pear who was captured by the evil wizard Haxor. It’s the players job to aim at the castle with the catapult and to avoid hitting prince Pear.

Wifi Lego Camera Robot: RoboCam
This is the first Lego creation I’m pubishing. It’s a robot with a wireless camera that is controlled from a computer over Wifi. Besides Lego bricks it consists of an Arduino Mega microcontroller, a Sparkfun WiFly Shield and an Edimax IC-1510Wg IP camera.
