I have one tube which goes from the top to the bottom and I inserted a Y - piece to split it. The Y-Piece is the small blue rectangular box which looks like it only holds the copper-pipe. From this Splitbox I went some centimeters upwards to the sensor which is hanging upside down. Perhaps moisture could be in the sensor but I believe it won´t because the spit has to flow these centimeters upwards. I planned to do more in this project but currently I only make acoustic music without any electricity… I hope my description helps.

That breath sensor looks pretty good, though I’d be interested in a 3d printed version instead of the rubber band and cardboard construction. You could then experiment with the diameter.

Thanks, that’s what it looked like to me. As I said before, “gravity will do.”
I think the scale is important too. That guy is using an optical distance sensor but for those using a pressure sensor at about 5mm scale it’s good to have parts that work well at the same scale. Digitisation of mechanical design potentially improves efficiency.
So, nothing happened for ages, then I received the 50cm transparent PVC tube. Now plastic is a lot easier to work than aluminium, and I also need to design a holder for the phototransistors. Maybe epoxy putty will work. But meanwhile I should install the firmware on the microcontroller and see what happens when I simulate sensor inputs.

Yeah, I get that. Frankly anything requiring organisation is beyond me. In 2011 I retired from the role of family printing expert because I thought (and still think) that print shops and cybercafes do that better and save the consumer the trouble of maintaining a printer. My son still has to fill in for my former role, and honestly I don’t understand why we should spend £100 or so plus the cost of ink cartridges when we can do a better job for a much better rate by going to a business run by people who get paid for it.
This is why I won’t even think about 3D printing.

Maybe you have a 3D printing shop right down the street. I don’t happen to know of any in my city.
(But my old inkjet printer did the “can’t recognize cartridge” thing for the last time a few weeks ago. I used to be able to get 3rd party cartridges that would work but no longer, and the extortionate price they charge for brand name ones is out of the question. Anyway I find I want to print in color so rarely it’s not worth bothering with that and the tendency for the print head to clog up. I turned it off and added it to my list for the next electronics recycling event. I do have a monochrome laser printer that’s far cheaper to use, goes much longer on a toner cartridge, and is much more reliable.)

BOOO INKJET
Get a laser printer, the toner lasts way longer, is cheaper and the prints are gorgeous.
Also, at least with mine, i dont have leftovers because a chip falsely claims its empty.

I certainly didn’t want to give anybody the impression that I equate the current commercial development of 2D printing services with similar 3D services.
Though in the two nearest university towns, both within 10 miles or a 30 minute trip for me on the Metro, there are 3D workshops that provide the kit and hands-on training at cost. If I wanted to use 3D methods I would have easy access to a variety of advanced printers, laser cutters and the like.
I don’t assume this is true for everybody. I live here because it suits my life choices, and living on a crowded island makes geography much easier to manage. But still it isn’t yet like going to the neighbourhood library with a USB memory stick and coming out five minutes later with a dozen A4 double-sided sheets.
I’m just not organized enough to use 3D techniques in the current state of the art. I’m barely competent with paper printers.

Start at 1099s to see the WIND CONTROLLER plugged through a MIDI to CV device.
I have a long professional relationship with akai ewi controllers and still have many to hand but my favorite, just for sheer flexibility and kudos is the simple emote midi controller project tucked away at the back of Brent Edstrom’s book Arduino for musicians.
It uses a teensy2 and a MPX5050GP pressure sensor which has two ports (so you can suck and blow) and a simple joystick for modulation, pitch, whatever you like. Basic and takes about 20 mins to breadboard.
The teensy2 gives you a usb midi out, but adding a serial midi out through DIN is straightforward, as is a serial midi in. (the world has too many optoisolators, stick a midi through in while you’re at it)
My eldest has one on their Roland Drum kit and breath + percussion is wild!
The emöte project is simple and very playable.
(forgot the umlaut earlier)
Enjoy
