I think I'm starting to get the hang of this "electronics" thing. Essentially, I would like to use one of the RF boards, figure out what each does, and then build additional node boards to communicate to. Being that it is now Friday, I still have yet to make any progress towards completing this week. So for the sake of time, I think I will just recreate Neil's asynchronous boards for this module.

As any other module for electronics, I started out by designing the bridge and node boards in Eagle, edited the images in GIMP and sending them to fabmodules for milling.

Once my boards were built, I downloaded the make and C files so that they could be programmed in Linux.

When programming, I went into the C file to be able to change how the boards would be identified when I use a serial monitor. As I prepared my code, I decided to use the letters A and B so that my boards would be identified.

At this point, thankfully programming my bridge board and one of my node boards was a success. Unfortunately, I am still debugging my other node to see why my connections seem to not be right. My intention is to get my final node working so that I will have more than minimum amount of boards for this module. A video to show my nodes working will be posted soon.
