EXPO Markers are what we used to make the LED Pens.

Role in the ProjectEdit

EXPO Markers were used as the basis for the LED Pens, because our school (Bioscience High School) has so many that aren't good anymore. We hollowed out the marker, fit a Battery inside, as well as some wires and a Button to turn the signal on and off.

TriviaEdit

  • The initial 2 were purple and green (the school colors).
