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:
My book on Amazon
My book on Adlibris (SWE)

Paperback: ISBN 9781910394717
Hardback: ISBN 9781910394724

Jag ha ett antal här i Sverige jag ka skicka för SEK 110:- inklusiv porto. Maila mig "harry.lythall(at)sm0vpo.com"

Anyway, I hope you have fun with my homepages. Very best regards from Harry Lythall - SM0VPO, (Märsta), Sweden.
