This is perfect. I recently picked one of these up and I have used a sparkfun breakout rs232 style board and a sensor to recive the data. I found some Python script but it doesnt work currently so I was toying with getting that working. Of course I got distracted becuase a 3d printer turned up and I was just thinking about making a model for the sensor. This saves me a few hours.
I guess the only thing to do now is print it all up and get it working. I wonder if the unit can take input, I know its go no sensor for receiving signals but it looks like they had planned to do it just never did it.
