EXPO Markers are what we used to make the LED Pens.
Role in the Project[]
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.
Trivia[]
- The initial 2 were purple and green (the school colors).
