As part of the ECE 476 Microcontroller Design course at Cornell University, two students have taken the game of Pong and added a new twist. This version of Pong can be played on any flat surface using two laser-sensing paddles and a laser projector that projects the Pong ball. The entire project only set the duo back $48. Hit the link below to get all of the nitty-gritty details about the game, how it works and even videos of the two designers—Adrian Wong and Bhavin Rokad—playing the game. Nice work guys.
