It's just amazing how far the technology has come. Now anyone can go 200+ if they want to. Just a few short years ago the list was very short. I wonder what it'll be like 5 years from now.
The elecronics portion sounds like fun. Once you get the nozzle build, maybe I could program a chip for you. The servo movement is incredibly easy; interface to the pressure transducer is simple. All that's needed is the algorithm for the speed curve and bingo...You've got an automatic nozzle. I'll see what the electronic component cost would be for a single unit and let you know.

Let me know if you need any other info. and I'll try to dig it up. Matt, it's amazing what you save!!! Nice going...
