found this one, you may want to play with the RC values a bit. there was one in a national semiconductor application note, but i can't find it right now.

Hi Unclejed

This is an excellent school project. It is not too sophisticated yet does everything he needs. Add a volume control at the back end of the op-amp and his project is done.

Good thing some listen to kids, other dictate to them.

Regards

Nico

or just change R1 on the second diagram to a pot...... that would do the trick as a volume control


Wow! So many circuits! Thanks a lot guys! now i'm having trouble choosing one:confused: ! hehehehe! But it's better than having trouble designing the circuit! :) I'm planning to build the one sent by minion though... but I think unclejed's circuit is nice too! :) hmmm... what should I do? hehhehe
