The other night I happened to see a tweet come across my twitter stream from Joe Walnes (@joewalnes) about a resistor color code tool he created. You can find it at the clever domain resisto.rs. Type in a value and see what the proper color code should be. This is great for when you need to go searching through a pile of resistors and want to make sure you have the code right.
Nice job @joewalnes!
Also, you can fork the code from github.
