Homebrew PCBs

Well, I too have done this in the past.. but my boards are getting more comples... current board consists of one 28pdip, and four 16pdid chips, 3 DB9s, 2 power connectors, 8 ADC channel connectors, a TWI interface, about 40 caps, 6 inductors, 2 fuse holders, and a power supply..

All on a 3x4inch  board... It's getting harder and harder to put this all on a single sided board
