Iceni Design

I do this once in a blue moon, tonight this was really useful. A form where you select the colours of the resistor and it tells you the value (that it should be). It might just be the cheap resistors that I buy but I found the every resistor I tested was at the very bottom of the tolerance that it quoted.
