Ei hope y'all are ready for some complicated circuitry. So we found out what we had to do for this wiring issue with the radio. It requires a TNC (terminal node controller) which controls the radio and tells it when to send messages and all that stuff. So we got the controller, and the transmitter. but what are we transmitting? GPS data! We need a GPS of course, so we are using the ublox 6M-V2, same as the arduino GPS. The problem is, the GPS is a 3.7 Volt and the TNC is a 5 volt. That means they need to be on the same voltage to even communicate. We easily fixed this by putting a Volt converter to lower the 5 volt output to a 3.7v. In case you want to buy one of these for your own project, take this link. http://www.ebay.com/itm/401258780242?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT We also used this other converter to help them communicate, from which is still the same problem as the power line. The TNC talks at 5 volts and the GPS talks at 3.7 volts. This converter allows the change to happen really fast. take this link to it. http://www.ebay.com/itm/172278416561?_trksid=p2057872.m2749.l2648&ssPageName=STRK%3AMEBIDX%3AIT In case you don't understand a lot of this, use this picture of it all to make it even harder to understand. We tested all this wiring with bread board. It was easier to draw it then actually wire it. Here's a picture of these two weird kids working on it: The next steps to do is the actually code all this. To be honest with you, I don't know if coding is going to be easier than the wiring.
