X-Ray Machine

Don't worry, it's not actually radiation!  This is how we made an X-Ray machine with littleBits!




This is the basic littleBits circuit:
power + roller switch + branch + timeout + buzzer + inverter + bargraph + led

When you press the roller switch, the timeout starts to sound the buzzer (making X-Ray machine sounds).  Quickly turn off the lights! Next the timeout turns off the buzzer, the inverter turns on the bargraph and led behind the two images.  The skeleton hand mysteriously shines through Greg's hand.  Pretty, neat, eh?

So that you can try it too, I've included the pictures of Greg's hand and the skeleton hand.
