small and quiet air compressor for a single pipe organ pipe? Answered

I've got a 2m long pipe (that I can blow with my lungs). I want to make it into a doorbell but don't have a compressor.
I tried a car horn compressor but it is so loud that it totally drowns out the pipe!
Any other ideas?

Hey I've seen this befor but how did you get ahold of the plans from the December edition of popular mechanics I've been trying to get a hold of it?

How about a bellows...

Here is mine..
Still have some fine tuning to do.

Do you have directions on how to build this?

Yes...
Here you go.
Enjoy, and post some finished pictures.
Mine still needs tuning...
As the weather changes, so does the tuning...

Get a large can - Put inside the bladder from a football. Between the bladder and the can put a home made pressure switch as in diagram.

one thing I forgot to make clear was that I want to use this as a doorbell, so a relatively 'once off' thing could work. It doesn't matter if the tube can only make a sound once a minute or whatever.

Use an aerosol compressed air can - through a pressure reducer to lower the volume a bit. Setting it off might be a problem though.

This is what I've gone for, it works pretty well; the only problem is that the can will need to be replaced every now and then, and that the sound of the hiss from the can is audible.

had a different thought - A weighted bicycle pump where the bell push releases the weight so pumping a blast of air through the pipe (may need bellows to get volume rather than a pump ).

A motor can lift the weight to re-set the alarm.

About the Bellows...

Make it like this:

Use a storage tank, and a very small compressor. Discharge the tank through a nice fat piloted air valve.

like a car tyre compressor? I'd probably need a pressure sensor then for the storage tank as well right? So I turn on the compressor when pressure is too low and then off again when it's high enough.

That's the kind of thing I was thinking of. You could do your own, but you need special on/off switch - I'd contemplate buying somehting from Machine Mart or off Ebay.
