ThumbStadium^TM is a 2-player hand-held electronic game that features 4 different games of skill. Easy and fun to build, Thumb Stadium is sure to provide years of entertainment while teaching electronics! Available either fully assembled or in kit form. Runs on 3 AAA batteries (not included). Size is approx 2" x 1.5" x 1" Free Assembly Instructions (PDF)

ThumbWar^TM -- The object of ThumbWar is simple: press while the other player is pressing. If you do, you get a point.
SlapJack^TM -- During SlapJack, Thumb Stadium randomly flashes the center LED red or green. Be the first to press when center is green and get a point. Don't press if it isn't green or the other player gets a point.
Jai Alai^TM -- Center lights up, quickly press to "catch" your color. Press again to "throw" to the other player who has to catch on time and throw back. The time to catch gets shorter each throw.
Reflexy^TM -- Reflexy is a one-player game. The object is to quickly press the button that matches the color in the center LED. You go until you miss or are too late. The time to react gets shorter each turn.

Write your own games for Thumb Stadium!
Because it comes with a socket, ThumbStadium also makes a terrific open-source educational/development platform for programming Microchip's 12F629 PIC Microcontroller:

To demonstrate the effect of Solar Power. Kit comes with a mounted Solar Cell 3-1/2" x 3-1/2", with terminals. A motor, a LED, a Rechargeable Battery and an Ammeter are mounted on a base 8" x 4-3/4", each with its own pair of terminals. When the Solar Cell is connected to the base and power generated from the Solar cell, on exposing it to the sun, is given to either one of the components, it begins to function. This demonstrates that Solar Power can be converted to Mechanical Energy, Light Energy, Battery Power and Current.

Includes high output solar panel with motorized reciprocating arm mechanism and high speed motor to build many solar projects. See who can build the most ingenious device.
