For Want of 0.1 mm…

I got the printed circuit board for my aquarium light and power controller project from Olimex in Bulgaria yesterday. It looked great!

Unfortunately, all of the holes for the connector blocks were 0.1 millimeter too small in my design. So the connectors didn’t fit. Which means the board is a dud. Who would’ve thought a four thousandths of an inch error would make a difference?

I’m ordering a revised board from Olimex today. Hopefully this won’t turn into a three times is the charm situation!
