47Re: Two months until TCF...
- Feb 10, 2005Oops, made a typo: I wrote "turns out I had two of the resistors in
backwards" -- meant that I had resistor #1 where resistor #2 belongs,
and vice-versa -- Bill P. pointed out that there is no such thing as
"backwards" for resistors.
The only thing backwards is my pathetic electrical engineering skills!
LOL, what do you expect, I studied industrial design in college. So
I can draw something or mold something or make something into an
assembly line. Just don't ask me to wire it. :)
