Hi,

...

This came up on the Open Source Consortium mailing list and thought it might appeal to/inspire OSHUG members

Yes, that is quite lovely and it seems to be an increasingly popular thing to do, which is good :o)

Not so much old tech, but if you like the sort of thing you might appreciate my friend Graeme's contraption that plays Gymnopedie:

Does anyone have an tips on where to get cheap air valves? I now have over three octaves worth of Champagne bottles for my bottle organ all nicely tuned but nothing to control the airflow with. Given the scale I'm looking for a (build or buy) solution < £1 per bottle.

I wondered if I might fashion something along the lines of this:

...using a similar solenoid technique and some plastic tubing and some resin casts?

Also, if anyone's got any empty Magnums or larger then I'd love to receive them.

Now when I see Champagne bottles I try to measure how many there are in octaves. Oh dear.
