    I have a friend who has his own business, and wants a little dinger for when someone walks in the door, and a "push button for service" button at the front desk. He wants it wireless too.

    I told him "okay, ill just make it go 'beep'", but that wasnt good enough for him, he wants it to go ding dong. So whats the cheapest easiest IC that I can use to make that sound?

    Why not just use your circuitry to activate the chimes on a doorbell unit. Most have at least 2 sound circuits with different sequences for Front/ Back. It would have some class and not be too expensive either. Don't build what you can already buy cheap enough.

    yeah, thats true, i wonder how much a doorbell is, ill have to check @ home depot or something.

    it comes down to whichever one is cheaper. I would imagine an IC would be cheapest though, all you would need is the IC, speaker, and a few extra components.

    The Seimens IC SAE800 will do ding-dong. I think it is available from Digi_Key.

    I like Dialtone's idea, a real door bell unit will sound right. A cheap IC will probably sound more like buzz-buzz instead of ding-dong and Zach's friend won't like it either. Hasn't everyone heard the square waves from the one from RadioShack?

    My metal American door bell unit wasn't loud enough. It was two vibrating bars in a box. I replaced it with a Chinese one from Home Depot that has plastic resonant chambers for each vibrating bar. It is much louder than the original one and the ding-dong sounds more pure and fades slower. The original one sounded a bit like clank-clank. :lol:

    Try a UM66. it is not a ding dong, it is a melody generator. Although it is an IC, it looks like a transistor & has only 3 terminals. A very simplistic circuit.
