It’s graduation season, and if you’re receiving your degree in a flock full of people wearing black gowns and caps, then decorating the top of your cap is the only real way to show your individuality. Most people write cheeky or inspirational messages on their cap that say something about them. But, Jacob Hoover isn’t most people, and instead turned his cap into a functional drone.
Hoover received his degree in mechanical engineering, so building a drone was right up his alley. He’s built multiple drones in the past, so he already had most of the parts he needed for the cap quadcopter. After reinforcing the cardboard hat with an aluminum frame, he got it flying with standard parts like a 4–in-1 ESC, RC receiver, LiPo battery, and brushless motors. Hoover says he tuned the drone for stability instead of agility — a good idea in a crowded environment — but it’s still capable of doing flips.
And the fun didn’t stop there. After the graduation ceremony, Hoover converted the drone into an RC car. He bent the frame arms down, and replaced the props with wheels. The physical modifications were the easy part though, and reconfiguring the flight controller to work for ground-based driving was more difficult than it sounds. But, he was able to get it working, and now has a cool RC car with a very special history.
