Final Product

Lizzie Beer

The final product, after two days of work, was a multi player game, where you would pass the ball and depending on the color shown, you would either "knee"  or catch the ball.  The structure consists of 5 rings laser cut into 1mm plastic material, with notches to stabilize them into place.  The sphere structure is covered by 8 foam strips laser cut to fit the circumference of the rings.  The strips are hot glued together and onto the plastic ring edges.  One of the strips is detachable through velcro.  The detachable feature allows accessibility to the electronics inside.  Two extra foam circles are hot glued to the top and bottom of the ball where the foam strips meet.  There are pipe cleaners that cover up the glue, and add a little texture. 

    The electronics inside consist of an arduino, an XBEE (that connects to the wifi), an accelerometer, and a battery.  With this setup velcroed down in the ball, it connects to the application on the computer which is called Processing.  With all these electronics programmed, the computer waits for the ball to be still for approximately two seconds, then shows either red or blue.  When the color appears, the person throws the ball.  The other person must either knee or catch the ball.  Red means catch it, and blue means knee it.  Once the person has the ball still in their hands, the process repeats.
