Unconventional Switch: Tappity Tap

    Life can sometimes be boring, you go to work and have to endure a long meeting, you have to sit through a long lecture. A good way to entertain yourself has always been tapping your pencil or pen on your notebook. Even that has started to get boring, so wouldn’t it be nice if a little light popped up to keep you entertained?

Our project was simple but effective, we attached our power source to a metal plate and our power connection directly to pencil lead. Using the fact that both the plate and the graphite of the lead are conductive, and our 100 ohm resistor lowered the power to not overly excessive for our light we could power the light by simply tapping our pencil lead against the plate. A fun activity to distract yourself while mindless drool goes on in the background, now including a light show.
