This summer’s Edgerton Center Engineering Design class produced four awesome projects in four weeks: - A functional RC quadrotor built with commonly-available RC equipment and an Arduino microcontroller board.  - A 4x3x(8x8) LED matrix screen capable, among other things, of playing accelerometer-based pong. - An illuminated polycarbonate-based makeover of the DIY self-balancing scooter featured in 2007, also with functional steering. - A lighter, faster, and more maneuverable Exkate-based electric longboard. What did you do this summer??
