Air compressors (here in the states) do this in their advertising by calculating the cylinder size, motor RPM and pulley reduction to derive a figure that in real world applications fall very short of the advertised volume and pressure output. That said, I believe it will be safer to calculate actual output of a large volume, then divide the volume by itself to know how much time is needed to generate the unit itself, albeit gallons, liters or ml. Heck even teaspoons and tablespoons.
My approach is to go about res building and correcting the same way till I can view the data and begin writing down important variables and such. It is my goal to code into the sketch actual manufacturer recipes, of course at 1/3 or half strength, or as needed. It would be awesome to leave this thing with my people in the event I die. Perhaps I took a few too many pulls on the pipe with that one, but the sentiment is real.
Do you have any ideas or leads on some good plastic valves with minimal cracking torque? I’d like to pair it with a servo and get the party started!
