For the past couple years I've been building and flying RC airplanes. Recently I've been thinking about getting into night flying. Doing so would take lots of LEDs on a plane, so I've been building an LED driver circuit. I just got the parts in the mail today and put together the driver above. It will drive 11 different led circuits and is the size of a 24 pin 0.6 inch DIP. I chemically etched the board using toner transfer and hand soldered all the SMD parts. The Eagle files are up on Google drive if you're interested.
