I’m graduating from high school on Saturday (6/18), but was dissapointed when they didn’t allow anyone to decorate their graduation caps. So, I decided to take a creative and semi-invisble approach to this - infrared LEDs!
Infrared LEDs emit infrared light, which can not be seen by the human eye, but shows up decently on a video camera. By putting IR leds in my graduation cap, nobody in person would be able to tell, but when i walk across the stage the cameras will capture it - blinking out, through morse code, “Congratulations class of 2011!”
I managed to make all of this the night before graduation, so escuse the messyness!
