I need to control something by hand that should look pretty (like a pot with a knob).
I need to control create a 1V-5V signal which comes from a 5 V or 48 V source (only need 1 and i figure 5 V is easier to use)
I was wondering if there was anything simpler than using a pot with a buffer after it?
I have done this before but there is tolerances on the resistances etc.
Here is an example schematic
