As you'll see in the video below, I have most of the firmware for the sensor/transmitter module complete. All I have left to do is remove the code used to drive the LCD display (which is only used for code development and debugging), and redirect the serial output to the transmitter module. Then a couple hours to move the components from a breadboard to the PCB proto area of the microcontroller development board. With those done, the sensor/transmitter module will be complete.

With the transmitter complete, I can turn my attention to the receiver and display system. I have most of the hardware put together and working, now I'll be able to receive the sensor pulses via the radio link and actually work with real data. 

I can now see light at the end of the tunnel. :-)
