Confuses me that anybody would downvote you for this. I’ve made makeshift capacitors out of rolled aluminum foil. It’s dumb, but it worked for what I wanted (triggering a trackpad via stepper motors for testing microcontroller code.) Plus I just wanted to see if it even worked. Life = science experiments.
I used to make shunt resistors out of a pencil and a piece of paper. Rub pencil all over paper, cut strips to size of required resistance.
EDIT: I mean megaohm resistors not shunt resistors. 20MOhm for DIY theramin.
I admire it but also…wtf lol
I made a potentiometer with paper and graphite clay once

This is exactly how high precision resistors are calibrated. A laser is usually used to notch out bits of the resistor to tune it after it’s made.
That’s cool, could you share some photos? The theramin I mean
