This is my Major Qualifying Project (senior thesis) at WPI. Our ultimate goal was to create a retrofitting kit to convert cheap single engine planes into autonomous cargo drones. In about 6 months, We made the world's first fly-by-wire single engine aircraft.
I was the electric+electronic engineering wizard, machinist, and embedded programmer on the team. I made gorgeous avionics.

SwagRocket555 was designed to ace model rocket target altitude competitions. The goal was to deploy a speed brake based on the rocket dynamics to make a rocket stop at a specific altitude. The control board is a Teensy 3.6 shield, with a 3 axis gyro, a 3 axis low-g accelerometer, a 1 axis high-g accelerometer, a barometer, and a differential pressure sensor (for pitot tube). It actuates a servo (for extending the speed brake) and ignites a electric match (for deploying a chute).
We made a robot that autonomously solves a maze fast without prior knowledge about the walls. I made the robot hardware (PCB+chassis) and some motion control. My friends wrote the maze solver, state estimation, and a Gazebo simulator.

I learned CAN bus by implementing a CAN-based real time network on the Robocart, a 1995 Club Car golf cart retrofitted for self driving car research at Wireless Innovation Lab. I made a board that controls the steer and brake motors and reads position sensors. The board talks to the onboard server via CAN bus.
