Help Please I want to build the Hall Effect Sensor as in the link

Rob were you able to fin the part number?

@Michael_Omiccioli I believe I found it. I’m in Canada and the http://Digikey.ca site unit price is $1.06CAD.

Yeah that’s about right, believe it or not its as expensive the Hall sensor. That’s what elegance gets you.
