My lawyer insisted that I add this DISCLAIMER: is a collection of  links to 30,000+ electronic circuits or schematics (more are added regularly).   I have carefully categorized and cross-referenced each one for ease of selection into over 500 electronic circuit categories.  Because I have not tested all these electronic circuits, I cannot attest to their accuracy; therefore, I do not provide a warranty of any kind and cannot be held responsible in any manner.  Thank You.
