Ping Pong Scoreboard

Ryan and Brendan Luu from Vumble generously donated their ping pong table to the Startup Shell space and it quickly turned into a crowd-pleaser.

With idea and funding from the infamous Jackson Geller, I smashed together a scoreboard with 4 buttons (2 for each user: green for adding points, red for subtracting) to make keeping track of score more fun.

It's powered using an ATtiny84 and a LED display from Adafruit and a 7.2V RC battery suspended under the table. The battery life turned out to be surprisingly long, topping out at a little over two weeks.
