Fold your own resistor value colour wheel

Thanks to reader Alan Metcalfe for bringing this to Gadget Master’s attention. He describes it as “a simple Mr Spock circular (resistor) calculator, to cut-out and make”.

The Resistor Code Calculator is on RobIves.com, where its creator describes it as “Paper engineering meets electronic engineering”! Like it.

Rob provides a link to a free PDF – via the site’s shopping cart process – containing the paper dials for printing, as well as the origami steps to fold it into shape.

The picture shows the Resistor Code Calculator determining, for example, that a yellow, purple, orange resistor would have a value of 47k ohms.
