Gwendolyn ScoginThe biggest thing right now is that the mouth piece assembly is working well. There were a lot of issues with the air pressure sensor. These seem to have been fixed by using double sided foam tape between the sensor and the mouthpiece. There is a small hole in the tape right over the air hole on the sensor. The foam is protecting the senor from moisture in conjunction with a small hole in the bottom of the mouthpiece.
The finger holes are small orings with wires inside used for capacitive touch sensors. This allows for a very light touch.
Right now its somewhat playable, but the next step is to add buttons for octave control and for the high and low notes.

Mouser has the same family of pressure sensors that I have at around $10.

It might give you a better playability with connections suitable for tubing.

I'm unsure what kind of air sensor you're running, but are you able to run a tube (I'm using aquarium tubing) vs the foam? Without more details or pictures and your comments about using the foam I would think that it wouldn't hold up over the long term vs other solutions. My pressure sensor is used in clothes washing machines for liquid level detection, so I'm not too worried about humidity.
I'm running mine with a closed pressure system, so you have to let air escape the side of your mouth, but in return circular breathing and other articulations are easier for me.
I know that some enjoy having a bypass tube/valve to simulate air flow through a real instrument, but I find it more limiting.

I'm using one of these

It doesn't have any external connectors.
I have a small hole to help the moisture drain, and then there is a larger exit for air bypass that can be controlled with a screw.
