For a good explanation of how PI detector work you can read Carl Moreland's Hammerhead article located here .Originally posted by eessoo View Posti can't afford one
but i can access one
i just don't know how to use it
and i'm in mechanical engineering so i don't really understand how this metal detector work
Instead of 74HC221, Surf PI uses CD4093 to generate sample timing. So, look at the app notes in the attached datasheet for an explanation of how the CD4093 can make a one-shot multivibrator.Leave a comment:

Isn't it time you purchased a dual channel oscilloscope so that you can troubleshoot logically instead of guessing?
