First experience with this design:

The internal treatment with linseed oil varnish was environmentally welcome, but practically a stupid idea. Because of the stench, the part has been empty open for a week and still stinks. I have learned that in such an application you leave the wood raw inside or seal it with odorless paint.

When closed, the silica gel pearls in both bowls darken within three days. Maybe that's the varnish too, but I rather think wood is probably good to keep cigars moist, but not so much to keep Sylphyo's dry.

I have to buy everything.
I want this garage!

Yes, if the screw just loosened, you can tighten it.
There are more like it on the Sylphyo, you should check them all.

The tool is called "Torx" or TX.
Quite common. From above it looks like a star.
Mine has the size "T10" engraved.

You can buy this tools as Bits or as complete screwdrivers or as wrenches.
The sets often include unusual shapes that can help repair equipment.
If you don't have such things, I recomment a solid box with assorted bits
and a Bit holder, preferably in SAE and metric sizes.

If you feel luxurious right now, you can look on Amazon for "iFixit Manta Driver Kit".
That is quite universal for household and electronics.
Or look directly at ifixit.com

Here is the prototype of my low-humidity container, which is supposed to keep the Sylphyo protected and reasonably dry. Seems to work, the long-term test is still pending.

The case is from Ebay, it's built by a hobby carpenter for displaying model cars and trains, and is originally intended for horizontal use. I just treated the raw plywood with linseed oil varnish.

At both ends the manufacturer provides acrylic glass plates, additionally I inserted two small wooden boards with holes. I put the Sylphyo only dry in, nevertheless at the lower board a usual kitchen sponge cloth lies, in order to catch possible dripping from the instrument. The small faces of the acrylic compartments and wooden boards have gaskets that rub lightly against the large acrylic faceplate. In fact, the gaskets are slotted sheats of audio cables.

To put the Sylphyo in or take it out, I slide the front panel up. The mouthpiece has its holder right above the Sylphyo’s body to remind me not to put it in with the mouthpiece on. The USB cable goes into the box at the back.

The construction is pretty tight, though not airtight in the technical sense. I trust the microclimate. If it works, I will probably screw the case to the wall. I have to add that I don't live in a very humid climate (Austria, Central Europe). With wooden instruments, for example, we rather have problems not letting them dry out from room heating over the cold season.

I hope the Sylphyo will feel comfortable in its new home, until now it had to hang in a cloth bag on a shelf.

Total cost:
Wooden box with acrylic glass panes from Ebay: €70 ($76)
1 kg (2.2 lb) silica gel from Amazon: €20 ($22)
Two nice bowls for the desiccant from the kitchen supply store: €8 ($9)
The other material like small plywood boards, some screws and linseed oil varnish I had at home.

We already had a short discussion about this controller in this forum:
Robkoo R1

Ah, I just read in the (planned) specifications that the Photon has adjustable airflow. Mechanically, I hope. If it comes close to the Sylphyo with that, it's impressive with the other features.

Then again, I wonder why I would put such a thing on the Sylphyo. We'll see if imoxplus really brings out the Photon and for which instruments there will be adapters. Aodyo has to programme the interface and their priorities seem to be elsewhere at the moment. But let's look hopefully into the future, maybe they are working on it right now and will be ready when imoxplus has the lost chips again :-)

Slowly, slowly... one strength of the Sylphyo is its very special sensitivity to airflow, which makes it probably the only wind controller that can really sound like a wind instrument. Of course, many of us would like something like the Photon mouthpiece, but it would make the Sylphyo a different instrument because the Sylphyo’s sensor is bypassed and the airflow is measured differently.

For me, it would be fine to be able to use the Sylphyo in two configurations. But I am not sure if I would still like to have these strange touch surfaces of the Sylphyo together with the Photon mouthpiece. I think with the Photon I would like mechanical buttons/flaps better. Special functions like sucking as a separate event are of course great, especially for experimental music.

But even though the Photon mouthpiece promises many features, I would actually prefer to have a better version of the Yamaha WX mouthpiece on the Sylphyo. To let the air flow through and to transmit the position and movement of the reed into the prepared slot to the Sylphyo electronics.

Thanks, now I can take a closer look and find a solution for myself.

Perfect!
I will send my Sylphyo to you in the future, you do it much nicer than me.

You're right. I did a little research on the web regarding the storage of circuit boards and electronic components and learned the basics pretty quickly: keep the parts dry or they will fail. Of course there are technical details, but I think as musicians we can simplify things and keep our electronic instruments dry with the same conscientiousness as we avoid drying out wooden instruments.

Which products do you use for your 3D printing material?
