FYI, I currently have set up two guinos on the same signal generator running to see if there is any consistency. I expect the injector open times will be slightly different due to frequency variations, but the injector and vss counts should be very close and so far they are, but will let it run for a few days. Also it is all rigged to run on the one 7805, hence the heat sink wedged behind it
I will try and leave it alone for a day or so.
