resisto.rs
I never have a resistor color chart handy when I need one. So I built a little web-app. Fast loading, simple, mobile friendly, and to the point.

This app is hard to resist. Get it?
Looks nice, but would look even nicer, if it worked the other way too i.e. it would be possible to input the resistor color code or smd code and it would display the resistance in ohms.
Keep up the good work!
Unless the author is practicing coding, this is pointless. The color code is the first thing a good technician or engineer learns. If you don’t know it by heart, you’re not a tech/eng, and have no business using resistors (and other parts) that use a color code.
It will give a person the color codes for a particular value (which may or may not exist in the real world). It won’t give the value for a given color code.
Also, no tech/eng would bother lugging a piece of equipment around just to figure out what value a resistor is.
And, the PC script works with ONLY IE9. Not everyone chooses to be in lock-step with Microshaft.
Cute but pointless.

I use resistors all the time. Yet I’m not a tech/eng. I guess I have no business using resistors.

That’s true. Though I’ll be adding that functionality next (reverse lookup) as a lot of people have asked for it. If you’re happy to leave your real name, I can let you know when it’s ready as I’m sure your constructive feedback will be really helpful. (Nah, not really!)

It’s been designed to run on phones, tablets, etc. I take my phone most places with me. However, as previously mentioned, I’m not a tech/eng – is it true that none of them take their phones around with them?

Erm, what PC script? It’s a web-page, that works on virtually all browsers on all operating systems. The other day I used it on the Midori browser on Debian on a Raspberry Pi. I’m certain that’s not IE9, though I may need to get a tech/eng to confirm that for me (unfortunately I can’t get hold of one because they’re not answering their phone).
