When I first set out to learn electronics several months ago, the first kit that I assembled was the Velleman Pong kit, available at ThinkGeek and numerous other online retailers.
I knew right away that some day I would find a way to mod this kit and make it my own. A few weeks ago I stumbled across an article on HackADay about a clever hacker who had modified his pong kit to receive input from his flexed arm muscles.
This hack got me thinking about different ways that I could interface with my pong game, but every idea seemed overdone and not very original. Friday afternoon I was driving home from the store when I got the idea of controlling the game using an Indo board (also known as a Bongo board, hence the name).
