It is a prototype, proof of concept. I Agree - it helps to make a snuffle-pinhole.

Hi, it is a real Ringbom, the displacer is driven by the pressure difference. Imagine an engine with two membrans, if you merge the membranes, you come to my design. Observe how the halfs of the bellow work independent in the last part of the video, when the motor is working irregular.
