Hi brandon,

thanks for the great resources.

The tracing of circuits is currently being done with a draftsman and tactile paper. Plus, a PF machine. The circuits aren’t the problem as such, it is just the PCB design. I am going to look at the grove shield, and see if we can get one to play around with.
