    some time ago i built a clapping circuit for turning on and off a relay..
    i built i from a book, it used a 4011 a few resistors some trransistors for driving the relay, and few components..
    it used a electret mic and it worked fine, :p exept :? it had the range of .......less then half a meter..so i coulndt use it for many things....
    so i tried to imroove it and ended up with a touch activated switch....
    and this is how it is now....
    but i want to build one with a bigger range, it should work in a small room
    actuly i only need it to send a pulse when the clap is detected, and the pulse will go to some driving circuits....
    now the problem, there is no problem till now....i wnad it to respond at a double clap, because i know tha the ones that respond to single clap can be easily tricked.....
    so maybe some ideas? :?:
    anyone got any circs that can do that?

    clap switch

    On the site i have made on geocities you will
    see i have used a 4040 IC. It is designed for a single
    clap. You must not be to far away to activate a lamp or
    something else.

    I know from 6 people who have made a design of a book.
    This is a clap-switch where you have to clap TWICE.
    This design comes from:
    Halfgeleidergids 2001
    And the publicer is: Elektuur
    It is sad because all 6 printboards did not work.

    The site of Elektuurs free download page is: (gratis downloads)
    http://www.elektuur.nl/dl/dl.htm
    I have searched all 2001 previews of magazines but there
    was not a design klapschakelaar (clap-switch)
    This design must be publiced in a special book.
    It is publised on two or three pages, i have only
    the first page.

    I don't know if you can order this book, but it is maybe
    beter if you ask someone in a Dutch newsgroup.
    I use Xnews program for reading newsgroups.
    Ask a question in alt.nl.gelicenceerd.amateur
    (i don't know the exact name of the group).
    This is a group of licenced radioamateurs. I have
    asked some and always get an answer.

    I you have made a good clap-switch, claping twice i would
    like to hear from you.

    Greetings. :wink:
