Searching for schematics? Circuit Diagram - Schematics is the language of electronics. It provides a concise and comprehensive diagrammatic description of a circuit. www.schematics.com allows users to connect and share designs and ideas in a like-minded community.
Did you know that I have written a book? "How to please a woman in bed". Nothing to do with sex - I suggest a man should get up early on Sunday morning, make breakfast and serve it in bed. Believe me, it is a lovely romantic start to any Sunday, and can give a massive kick to any relationship.
There are several links:

Paperback: ISBN 9781910394717
