The folks at NerdKits, who gave us the DIY Marque LED Array Project, now built on that project with the DIY LED Heart for Valentine’s Day. Using their USBNerd Kit, 20 red 5mm LEDs, and some cardboard, Humberto shows you how to create an electronic Valentine’s heart that twinkles and prints out messages o’ love on an LCD display. As the video says: “Think about it. How many girls out there can say that they’re Valentine’s card runs at 14MHz?”
