A few years back I started the initiative to build an open electronics lab for students at my university. Some friends quickly came aboard and together we convinced institutes to share barely used equipment, companies to give us discounts and managed to win a price, giving us some cash to spend on awesome tools. Last year, the company LPKF kindly offered to lend us a professional PCB milling machine.
Since I moved to a different town for work, I haven’t had much time to play with it or work on projects in general, but here are a few PCBs I recently milled.
The pogo pin adapters will be the programming interface for coming ESP8266-based Boards. They feature 2mm-pitch pogo-pins with a X-XXX layout to ensure polarity and allow to program the board from top, edge or bottom.
