First real Gherkin I've seen
The Gherkin Pi by /u/willbill642.
I have seen a few boards built with the Gherkin PCBs, this is the first one that did something really different.
With this I consider releasing the gerber files as opensource a success. The PCB's are simple and cheap enough to try out new ideas.
I am looking forward to seeing what else the PCBs are made into. The cost to have your own PCBs made are relative low ($16 per set of plates shipped to just about anywhere) and you can sell the ones you don't use.
