This week my output device was to control an electric stike plate to open a door. The system reads in rfid tags through an RFID scanner and checks the keys againt a master list of good keys that are updated my a local server in the room.
In order to attach headers to both sides of the board it was necisarry to make a two sided board. This worked will in the inner sections but around the edges the copper started to tear away from the board when I pulled it up to flip it over. This caused some pretty rough routing but the board still worked in the end.
Here's a video of it working:
