Having a PCB ruler in the hackerspace has always been an interest at our hackerspace, but we never actuallly designed one, until now. PCBWay has kindly offered to make some of our PCB rulers. There are quite a lot of PCB rulers out there, but I always thought they could look better, so I designed my own, and thus something that is both useful but equally beautiful. And since eLab hackerspace logo is black and white, it only made sense to use a supper cool matte black soldermask with white silkscreen. As for the copper layers, nothing looks better than gold on black! You can get your own here!
