I want to modify it for my special application.


I had the original Harbor Freight unit pretty well figured out,
and made several modifications.
Then they went to surface mount parts and changed the type of circuit,
and the parts considerably!
I gave up on deciphering the new unit.
If you get info, I'm interested.
