This project was part of the student-initiated 5in5 Project (http://5-in-5.com). I had obtained the Peggy kit, but was a little upset that it was designed for creating a static sign. Once the LED's were soldered, they could never be changed. So instead of creating a single image, I decided purchase 650 female headers so the LED's could be changed at will. The result it the Peggy Lite-Brite! The work involved 1502 solder points and about ~7.5 meters of solder...which took about 7 hours to complete.
