content: It is not worth sorting these resistors, when the amount of work is worth more than the resistors themselves. And it is more time.

content: Quote from: NANDBlog on April 14, 2014, 02:10:40 pmI agree but there are other reasons for wanting to identify a resistor, such as fault finding.

content: Good luck to me finding the difference between red and brown (or purple and blue) on a blue background! I struggle with the blue ones terribly.I like this project, an app that can reliably identify a resistor colour code would be nice. Could be useful for identifying in circuit.

content: Quote from: wilfred on April 15, 2014, 08:20:06 amExactly that, there is no way that you can sort bunch of the resistors by reading colors. Even sorting with a multimeter is terrible work.So I think that this application is a great tool for first step in sorting bunch of resistors.Later on when you need to use one of these resistors just check them once again with a multimeter. I do that even on the brand new resistors, you can never know..I'll give 100$ for sorting resistors in bunch on the picture. It weights few kilos. Anyone interested?
