Classic Video Table Tennis Kit
What it is: The Classic Video Table Tennis Kit is a build-it-yourself Pong-style game kit.
Why it's awesome: The kit comes with a preprinted circuit board and a handful of electronic parts, just waiting to be assembled. All you need are some basic soldering skills, a screwdriver and three AA batteries. The game even has four difficulty levels and one- and two-player modes.
