This device is a tribute to one of the coolest movies of recent memory, Eli Eli Lema Sabachthani
. In the movie, the protagonists improvised a lot of cool instruments with the goal of making a pure and beautiful noise. One of the most striking things they made was a droning machine built out of an old fan, an umbrella and some drainage tubing. You can see this device in action 56 seconds into the movie trailer
After dreaming about making one for a long time, I finally went ahead and did it. It was a lot of fun to make, and it worked pretty much as advertised. The biggest problem I encountered is that I was over driving the fan motor and I probably could have chosen a more powerful one that could have handled more tubing (more weight). I will solve this problem for revision two.
Anyhow, without further ado, here is how to make your own.
