if i sent you a un prototyped schematic could you build and debug it?
 maybe i will build one using a pic16 up as a little learning exercise
the pic only costs $2.50 us  and  can do the whole thing   with just
a little stepper driver circuit  and a dip switch for open and closed 
pintle position; if you could pulse with modulate or vary the frequency
of that output  it would convert that into counts.  
maybe a solonoid valve and  a needle valve would be easier for you
does any one else out their have any interest in this project
i am trying to come up with new pic16 applications and have 
developement hardware and software  for it and eproms ,intel 87xx ups
currently i can only program the 165x series because i have not 
upgraded my programmer.
