Introduction: Resistor Companion
I know how to calculate the resistance of the resistor, but as a hobbyist, I never remember the color code and the equation. Moreover, I did not get the difference between "orange" and "red" color for those old 5% carbon resistor.
One of the direct method to know the resistance is using multimeter, but finally I think a "real" resistor scale is much better for me, so I make this "Resistor Companion".
Making this resistor companion is easy, just print the last jpg to the printer and laminated it.
U need to make small holes and placing the resistor on it.
The laminated paper is strong enough to hold resistor and u can even make a smaller one for daily use resistor.
Probably, u can make a "resistor storage" as I make before.
