I want to make a bunch of breadboard modules. I don't want to use standard square pin headers and machine pin headers aren't as long as I need. I have used 22 AWG tinned wire, straightened, but it is easily bent out of shape. The material used for the legs of 4-digit 7-segment displays would be perfect. Anyone know if there is a supplier of this? Besides an industrial supplier to manufacturers of 7-segment displays.
