Thanks nuno, has that already been mentioned and I missed it? Lucky guess on my part. Anyway, how would the size of the pot be determined? Does the controller send the 5V line through a resistor for low? If so, could the value of that resistor tell us what size pot to use?
I know very little about electronics, but I can solder. Adding a pot seems like the way to go. I can't imagine why the manufacturer didn't put in a pot for speed control.
Am I correct to assume there would be no worries adding a pot to the 5V line? It's been mentioned that some ways of speed control might heat things up and damage the pump.
I don't think anyone has responded to this, but it makes sense to me. However I also am electronically challenged and would like to know if this is a good idea.
My WP40s are due in this week.
