Seeing red

I’m definitely not angry, though.

IMG_20140217_121942These lucky LEDs (39 of them) will be part of my name tag project. The only power supply I have left is a 9v battery. With 620-ohm resistors, the current draw won’t be very much. Hopefully that helps the battery last longer. There’s also an Atmega chip that will be draining the battery. Each letter of my name will take one PWM pin. The next step is to find material to mount the LEDs on.
