Hi,
I want Simple sound annunciation circuit because it is more effective then the other circuits.

Snoreta

 

Like a doorbell?

 

Kids are not cheap, but they are noisey. More fun to make too.

 

If you have a cat in your junkbox, step on it's tail.

 

See what happens when you don't leave enough details?

You get lots of help, but very little of it helpful.
