Simple Parabolic Microphone

This is an arm for holding a lavalier microphone in a DIY parabolic dish.

It is really a lavalier microphone holder that fits into a 3/4" threaded bulkhead fitting.

The bulkhead fitting can be placed into a parabolic dish, large bowl, trash can lid or just about anything shaped to reflect/focus sound on a mic.

The v2 files allowed me to increase the focus distance to the mic. I was not happywith the threads and removed them for this version.

Items used on this project:
1. Large clear plastic pebbled bowl (mine is 400mm across)
2. 3/4" PVC threaded bulkhead fitting
3. 3/4" PVC threaded elbow
4. 3/4" PVC pipe (makes a nice handle)
5. Lavalier microphone
6. A few smalll zip-ties

The arm, base and bell cover is what I used.

Files are also included to print the whole thing with supports.

Configured as shown, this microphone is 90mm from center/bottom of the bowl.
