Was going to try making one of these for the fun of it, and it was just too frustrating. First attempt: plastic melted to the contacts (and my iron tip)in no time flat.
Second: Tried pulling everything out and take the plastic out of the picture. The damn pins are thin, springy, and won't stay still.
I give up. You need 3 or 4 hands to do this crap.
