Get an eye test? Haha why I have colour blind mates.. I know I'm not colour lind or anything.. and IMO I have good eyes.. Anyway are you saying that the grit cold be f'in it up? And no I don't have a multi meter myxr, but it would be a good thing to have around I supose.. How much can u pick em up for round abouts? Pretty cheap? I have heat shrink, I could use that.. But i always thought that might shortit out so I never used it, yeah my colour blind mate actualy has a solder I could borrow, so I will solder them up and, yeah he dose.. But he only knows what I have taught him. So anything i am still learning he probably won't no about.
