Papercrafts at Adafruit! We’re excited to share this Resistor Helper you
can download and make yourself. It’s the newest tool in our
Circuit Playground
family– when you can’t get to your iPhone or iPad, use paper! One side
helps you read 4-band types and the other side takes care of 5-band
types. The Resistor Helper is on
Thingiverse as a PDF (with Illustrator editability preserved). Designed by Adafruit with
Matthew Borgatti. You can also grab the
PDF on github.
