Post by thread:[EE] Resistor of X Ohms looks like what?

Posted on behalf of James.... I updated the page for Resistors at http://www.piclist.com/techref/resistors.htm With some links to web pages that quickly answer common questions about resistors. (e.g. what value is it based on the color codes, how to make an X ohm resistor of any value by wiring standard values in parallel) and I added a new page that I wrote which shows you what a resistors color bands will look like given the ohmage and tolerance. I was working on something today that needed a bunch of different resistors and I got tired of converting the values to color bands in my head (actually, I got tired of working on the project) so I wrote this page that just shows you what to look for in your junk bin. http://www.piclist.com/techref/resistors.asp Check it out and tell me if you see any errors or problems with it. Knowing me, I probably missed some MAJOR issue while nailing down all the details. The script is sort of interesting because it doesn't use any pictures to make the pictures.... The images of the resistors are actually just tables with tiny cells of different background colors. It's far from professional javascript but it works fine in Google Chrome. :) James Newton spam_OUTjamesnewtonTakeThisOuTmassmind.org 1(949)743-1447 phone http://www.massmind.org/member/JMN-EFP-786

> Check it out and tell me if you see any errors or problems with it Great start Suggestions - Add 1.0 - 9.1 ohms. eg 4R7 5%, yellow purple gold gold Disallow illegal values like 331 (I think even in the 0.1% range there's no 331) Depends what you want the page to be and be for. E24 1% is a pretty common range. E96 and E192 much less so. And doubtful if those parts would be in the average junkbox anyway, getting specialised

Works OK in IE7, but not firefox 3.0..... Nice idea though.
