This is a recipe for long-term unreliability. All it takes is a little bit of oxidation between the device pin and the wrapped wire. You aren't really wire-wrapping at all: those sharp-edged square posts are *important* to wire-wrap, because they bite into the wire and form solid gas-tight contacts that are reliable forever. (The bites are why you shouldn't re-wrap wire.) I'd strongly advise adding a bit of solder to make the contacts reliable, at least if the gadget is meant to last. -- If the Space Shuttle was the answer, | Henry Spencer at U of Toronto Zoology what was the question? | henry@zoo.toronto.edu utzoo!henry
