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, 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?
