The final design project for Intro to Electrical and Computer Engineering (ECE 110) was a self navigating car. This is the design my partner and I built which was the first car to navigate the turns, zig-zags, splits, and stops of the course all the way through on its first try. Read on to see how it was done.

This 3 speed automatic transmission was built out of Legos. The transmission is driven mechanically, as there is no motor or external device required to change gears. It works using a spinning wheel that contracts and expands. The spinning wheel is connected to a gear shaft that moves between 3 states. At rest, a rubber band holds the spinning wheel fully contracted. As the car’s wheels speed up, the centripetal force required to keep the spinning wheel contracted exceeds the force of the rubber band, causing the spinning wheel to expand. So as the spinning wheel increases speed, it expands and the gears are shifted. (more…)

As a senior in high school with some knowledge on electronics and mcus, I couldn’t pass my last year without building the ultimate senior prank. The prank involved hiding a remotely operated water gun, built from scratch, behind a door and spraying students as they walked down the hall. (more…)

The press of a button triggers a chain reaction built to launch a single dib across my room and into my mouth! (more…)

The turret is built completely out of lego pieces. It uses a structural design to support the airsoft gun and keep it stable when moving. The sideways motion is controlled by a motor connected to a turn-table through a complex gearing scheme. (more…)
