Who needs a resistor calculation tool?
Well, if you’ve ever tried to make up an odd-ball series or parallel resistor values to a desired accuracy from various E series ranges then you’ll know how annoying it can be, especially if you have to to do it over and over.
I wrote a tool once that did this, but was fairly limited.
I’ve been searching for a long time for a similar tool and I finally found one that worked just the way I wanted it to. It’s called Resistor CAD 2.0 by Terry Harris from Vader Systems.
Vader Systems doesn’t seem to be around any more, and the program was free, but now seems almost impossible to find. So I’ve put it on my server to share this really useful tool.
Download it HERE
There is also a similar online one HERE, but it’s fairly limited.
