Long time no post - making new boards

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.
