Just a quick note that the next step in this project is to make an Android app that receives each frame and displays it / saves it / streams it / etc. I'll have a longer post soon in which I work out a feasible featureset for the first version of the app.

I also realized that I positioned the RFD22301 unit on the board in a way that might diminish longer-range RF performance, although in experience so far I've had no trouble connecting with a nearby Android. If time allows, I'll make another version of the board with on/off switch, a repositioned RFD22301, and (possibly) a charging circuit.
