Just added some new parts to the Pinbox Jr. prototype.  First, a new power rail breadboard to help handle all the ground connections... the little red breadboard wasn't going to cut it anymore.  Second, the Pinbox now has it's own short USB cable that's always attached.  Finally, and most importantly, Pinbox Jr. now has an accelerometer inside the box!  There's no support for it yet in the code... but the intention is to use this to detect bumping which will then translate to in game tilt.  What's a pinball game without tilt?
