I am an Electronics Product Design Engineer, I used to work in the R&D Areas, Designing Electronic Products. Then i had my own firm, manufacturing Instrumentation and Scientific Custom Equipment.
I started designing circuits in the early 80s. I came online in the late 90s. My first circuit site was made of the PDF circuits that was part of the Engineering Documentation of my own Firm started in the early 90s. I put it online as they were of educational value and could be useful reference to all.
