The Adafruit blog just posted a neat papercraft resistor calculator. If you haven’t yet learned the horribly offensive mnemonic for resistor color codes, now’s your chance to have a cheap and portable ...

Resistors are the most commonly used component in electronics, as their purpose is to create specified values of current and voltage in a circuit. Since there's so much to understand about them, being ...

If there’s one thing that will surely blind us, its reading resistor color bands. It doesn’t help that red looks exactly like orange, brown and black are indistinguishable, and different component ...

This is a handy resistor colour code “calculator” that doesn’t need power supply or to be installed on a PC. As you know most resistors use coloured bands in order to show their value. So basically ...

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 ...

This PowerPoint is to be used with whiteboards. Students should be given either a resistor calculator wheel or chart, students will be shown the resistor with the first click, students work out the ...

Many times, the need arises to interface single-supply analog-to-digital converters (ADCs) and comparators to real-world signals like 5 V. Of course, it's possible to condition the signal using ...

This pdf contains 2 copies of the Resistor Calculator on one A4 page. Print onto card so that your students can make their own. You will also need one paper fastener each.
