Another idea: Bottle Organs!

Ever blew into a beer bottle? - Gives a nice sound, doesn't it?

An empty one litre bottle gave a "A#2"; almost filled it gave a "A#4". Cool! That means 2 octaves.

How deep does it go?

After knowing that the PVC pipe flutes are easy to make the next question is which tone would be the lowest that could be reached with commonly used PVC tubes.

With a 2" tube I built a "C3"-flute. The next experiment was using a 3" tube, which gave a "A#2"(116,5Hz). The length is approx. 140cm. That means the organ will easily cover at least 3 octaves.

To calculate the scales, I found a useful calculator in German language:

First flute works!

The most important experiment is a success: the first flute made of an old pvc pipe works!! This easy experiment is at the same time the most important one; it answered the question of "go/no go". The pipe made of a copper tube didn't work. Copper would have had a cooleer look but at a 5 times higher cost.

the design is based on that clip on youtube:

Klangtube Wind Project Members

Cool! Found two friends who will support the Klangtube Organ Project, Zwax and Wolfgang

Wind Organ Project

After having built around 40 Klangbox string instruments I have got another challenge: Building an organ.

The project was inspired by this clip on youtube:

The current project shall finally consist of an organ with an not yet quantified number of pipes, modular solenoid valve-blocks, the air supply, a homemade keyboard and a midi controller.
