It doesn't look right to me. I was thinking of the one posted in #6 which looks good mutatis mutandis.
I think this circuit have an issue with my application.
I open/close the valves rapidity, on the first time It will work great, But If I opened again after a small time the capacitor will not have charged yet, And the open pulse will not be the same, (I THINK SO) !
That's why I am interested in the mentioned on replay #8, On Fig 3, It all about rapid speed operation, And looks very promising on Scope too.
Accurate open/close voltage every time at high speed.
sounds like you have the same challenges!
Yes I do
I am trying to fine tune every piece step by step, After making the control PCBs working as best as I can, I'll play with water flow,pressure And lights to make it better ! Thank u
