I have not but you certainly can do it. The length of the tube will determine the peak resonant frequency and you would have to experiment with the length to tune it to the pitch you like best to listen to. 
Remember the days you would blow across a bottle to make a tone? The more you drank out of the bottle the lower the pitch. 
I like this project and I am going to build one and it will be with a straight tube mounted on a little stand so it aims towards me.

 Has anyone built the resonator with a straight length of tube? Perhaps terminated with a 45 deg. cut? 
Might be an interesting experiment. 

The 45 deg long radius street elbow in 2" is an order only item in my area so thought I'd substitute a straight length.
