Interested in making a DIY dingbat

[Desmond]

Just curious: how is the piezo attached to the tube? Is it just 'floating' inside the tube? Has anyone opened one up and looked inside? I saw a thread where someone made one out of PVC pipe but didn't elaborate on the internals.

I made one by attaching the piezo to an l-bracket and jamming that into the tube so that the piezo is parallel to the striking surface. It's hard to attach the piezo to a curved surface, so you can use any flat piece of metal the diameter of the tube and force it in.

Thanks! What kind of tubing did you use?

you could also make a foam sandwich. (foam-piezo-foam) and push that inside the tube. i would go for pvc.
good luck and keep us posted.

Almost any kind of rubber :"wedge" contoured to the tube with a flat surface to mount the piezo will work. Then just silicone the rubber "wedge" to the inside of the tube and mount the jack on a cap in the end of the tube. Very easy build.
