Montague,

Yes I have a scope. I just figured somebody has already done this and would save me some time. I hate re-inventing the wheel, If you know what I mean. Well I figured by the $20 dollar price tag that they were just using a simple regulator like an LM317 or equiv. (Or mabey kids build them in Mexico or China.) Well, I'll hold out to see if anybody has any information before I borrow one. Gee, I'm begining to sound like a couch potato.
