I talked with Ying about the circuit and she was concerned about how much power the valve would draw. I will have to test it with our exact valves as she is familiar with different ones. At worst we would just need a few more of the ICs, uln2003a, to power all of our valves.
My test circuit is almost done. If all goes well I will test it with one of the unused valves or a non critical one like the sputter shutter.
