PCB in 5 hours.

From zero to PCB in 5 hours of work. Designed in Eagle, milled on the CNC mill and assembled by hand. The tolerances are pretty low, so I was able to get away with using the same end-mill for drilling and milling. The PCB in question is a power supply for a pair of silicon photo multipliers. The SMA connectors probably going to need some hot glue strain relief...
