YouTube user DerAzghul built this sweet resistor checker that displays the rating of a resistor using colors generated by some RGB LEDs. Love it! [via Embedded Projects]

    hey hes holding both resistor wires with his bare fingers!

    Totally cool design! But…… I would have incorporated an LCD or LED display of the numerical value as well. I mean, while it is AWESOME to look at, it’s not very functional. You already have the color bands of the resistor right there on the resistor after all!
