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:
