Here is my K-40 panel for now. I did not get all the parts in that I want to use but here it is so far. Nothing special. :smirk:

Nice. Are you using two tone acrylic or painting the engravings white?

Paint. Too poor to get 2 tone… LOL

Nothing wrong with paint, it’s what I did with mine. Used silver calligraphy ink, makes it sparkle a bit :slight_smile:

What is the Pot. (V) part and how is it connected?

(Ned Hill) #6

Ah, excellent question :slight_smile: That’s a voltmeter measuring the voltage between the In and ground pins on the potentiometer. The voltage is directly proportional to current so I can just turn the pot to a voltage.

Oh, ok. I have a bunch of those I used for vape mods :stuck_out_tongue_winking_eye:

Yeah it’s a 3 wire meter pulling off the 5V on the power supply to read voltages below 3V.

This is the style I have. No docs for it. Lol.

Gives you an accurate pot position by reading the IN voltage. This way you do not have to have graduations.
It’s a value of 0-5.
