Without too much trouble I wrote an Arduino based program for an VDI module.
I had originally posted this under the IDX section but maybe deserves a thread of it's own since it should be able to run on a variety of detectors. I just happen to be using the an IDX kit, minus his VDI module from Silverdog for this experiment.
I struggled with this for a few days until I got the accuracy down but now works perfectly! Problems I ran into were determining how long to sample each channel and inconsistent calculations using floating point numbers.
I used an Arduino UNO, just because it's the most popular. Documentation for the Arduino is excellent, so even a hobby guy like be could figure it out. Basically the program monitors the last stage of the GB and DISC channels, takes 50 samples of the ratio between the GB and DISC channels when both are triggered , throws out any bad numbers, averages them and displays a number that is porportional between 0 and 100.
Details of the Arduino are here:

Here is a link to my experiment:
