This is the second version of the Wind Vane PCB design. The major change in this design is the addition of the microSD socket. The socket will be integrated in the design to facilitate the data collection and reduce the breakout boards needed.
The boards have arrived! I started to mount the sensors and the and other components on the boards.
The first version of the design was completed 7/15/16. These designs were sent to the fab 7/21/16. The time estimated to arrive back at the lab is about two to three weeks. As soon as the boards arrive we will start the assembly process of all the pieces. Click on the pictures to take you to the github repository.
We have printed working prototypes for the soil vapor sampler! These are the first three. These pieces have undergone an acetone vapor treatment to increase structural strength. The vapor treatment also gives them the shiny finish on outer surface.
