Younger electronic engineers may see resistors with old-style color codes to display their values a little less than those from previous years, but if there’s a shibboleth among those who wield a ...

The fun of having a giant resistor-shaped Ohmmeter is that it reads back the resistance by displaying the color code. If you’re not too hot with decoding those bands there’s a helper band to the right ...

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 ...
