Resistor
R. Stern writes –

“I work in a computer lab with a physical computing studio, and recently I cleaned out the component closet. It occurred to me that the reason we had a build up of unlabled resistors was because noone knew how to read them without the Resistulator widget or a resistance calculator website, so I made a sign to tack into the cabinet itself for offline calculation. You can download the PDF for your own use. “Link.
