I have successfully assembled the project by hand, but currently I am exploring pcb assembly options among the PCB manufacturers. This will enable the small surface mount parts to be soldered on while the larger parts can be provided as a kit for those who want them. However, I'm not sure yet how far down the line I should pursue this path.

I'm also exploring mounting options. No use having a nice shield if the LED is all spaghetti-ed on the floor.

Lastly I'm writing the code that will allow anyone to just plug the shield on and have it start working immediately. This is taking a bit of time.
