 Wunderbar, schön, sind wir wieder da für diesen letzten Outro mit der 5 drauf, Workshop-Ergebnisse. Wir haben einiges gehackt, diesen Tag und die letzten 2-3 Tage habe ich auch mein Bestes gemacht, nochmal Informationen zu dem Thema Flöten zu geben. Ich werde das in Englisch sehen, wie die andere Zeit. Wir hatten einen tollen Zeit during the workshop today on working on flutes and hacking simple things like a hole in something to blow on it to see if there is any sound inside. So, and I prepared some flutes on the internet on the website. People could download it. I thought we would have some 3D printing going on. And actually I noticed myself that it was very short time to actually make a new flute. I printed one that is a completely new nightly build design, but unfortunately due to the very little limited time I couldn't print it in the right size. So, it might work in the right size, but this is too small. I figured that out. I wanted to introduce Gandalf. He's the one that participated here in the Bitwäscherei. Also, hier in der Bitwäscherei haben wir heute mit Live mit Gandalf diesen Workshop durchgeführt. Da wir also nachher gleiche Ergebnisse erzeugen. Ich würde nur noch gerade erzählen, dass ich das zu klein gedrückt habe, mangels Zeit. Weshalb ich nicht weiß, ob mein eigenes Ergebnis jetzt was geworden ist oder nicht. Ich muss es nochmal größer drucken. Vielleicht funktioniert dann wieder eine Pfeife. Die ähnlich wie diese Pfeife funktioniert, wo dann ein extra Luftkanal des Wasser beeinflusst. Das ist diese Flöte, die jetzt als Ausgangslager auch gedient hat. Aber wir sind eigentlich dazu gekommen, um alles zu eine Flöte zu machen. Es ist egal, wie es aussieht, was es kann. Es soll nur vielleicht ein bisschen Resonance-Body haben. Ich zeig gleich noch ein anderes Ergebnis. Das hat jetzt sehr gut getönt. Das tönt weniger gut, wenn ich Wasser rauslasse. Zum Beispiel kurz hier rein. Da kann man noch kurz den Echtheitsgehalt überprüfen. Geht auch noch. Wenn ich jetzt noch ein bisschen rausnehme, ich tu das in die Flöte, die kann ich nachher auch gerne noch spielen, weil wir machen ja Performance und kein Workshop. Der Ton sinkt langsam. Und dann kriegen wir gleich einen Punkt, wo der kaum noch hörbar ist. Auf einmal ist dieser schöne Resonanzkörper weg. Der bleibt noch relativ gut. Gut, ich lüge. Also, das ist nicht genau das Experiment, das ich wollte. Aber ich werde jetzt über Tugandalf, der heute den richtigen Workshop gemacht hat, einen schönen Instrument zu hacken. Und ich werde ihn erzählen, wenn er sich selbst explodieren kann, wenn du nicht meintest. Vielen Dank. Ja, das ist ein schöner Workshop. Ich hatte es schon vor, bevor ich auf den Topf gekommen bin. Ich habe mich über diesen gearbeitet. Du hast gesagt, du hattest nicht die Zeit, um den richtigen Stil zu bringen. Ich werde es für dich noch einmal versuchen. Aber es ist eigentlich... Der Resonanzkörper wird eigentlich die Frequenz, man könnte mit der Frequenz enden, dass es möglich wäre. Aber du kannst es noch einmal auf die Frequenz holen. Vielleicht sehen wir, ob ein Hund auf dem Stil ist, wenn ich ihn auf den Stil stehe. Was ist das? Okay, das ist toll. Vielen Dank. Es ist ein schöner Workshop. Siehst du, dass die Stilz in die Frequenz kommt? Ja. So, über den Workshop, wir haben hier einen Workshop, das in diesem Workshop ist. Ich würde gerne ein bisschen der theoretischen Unter- oder Unterlagen-Theorie geben. Das Kostfer-Tofen, das ist alles... Es wird sehr schnell kompliziert, weil es nicht nur Dynamik gibt, aber ich zeige dir das schöne Drawing, das Kostfer für mich hat. Und jetzt schauen wir, was wir sehen können. So, über hier... Das ist eigentlich, was du brauchst. In order to create the whistling noise, we have a laminar flow of air, which is just the air flowing nicely, gently, not evident. You make that move across a sharp edge, which you see somewhere here, there's a sharp edge, where you blow over, which separates the air flow into two flows. And you see these little, what is called vortexes, which is the turbulence you cause by splitting the air from a laminar into a turbulent flow. And the size of the vortex, the size of the disturbance basically is an oscillation that creates a pressure wave, which is, if it's in the right range of the expected spectrum, is audible to human beings. Is that about how it works? I was exactly unaligning it by experimentation and I tried to follow a sound that creates the understanding of this. Because it's all invisible. The wind and the vortex and the sound is this sense totally invisible. Also, that's what I think you noticed in the workshop as well. It's really hard to basically see this invisible thing hitting that edge and let it, yeah, imagine to flux away with 50 Hz or more in this sense. Absolutely. The funny thing is, I'm into paragliding, and I'm quite familiar with flying in this medium, which is a liquid medium. It behaves like a liquid, so it's all fluid mechanics which gets super complicated, very, very quickly. And the thing is, I would love to make underwater flutes that do the same with water. Basically, I'm on the edge of discovering how to make a flute that sounds underwater. The water is not compressible. I mean, that's going to have a huge effect. It's going to have, ships having their propulsion in the water that does something like that, an edge through the water, yeah. No, but that's because when the lake is super sonic, it creates a, what do you call that? It turns the gas sort of the way. Are you talking about propellers of ships? Well, I'm thinking of how to make a flute underwater. So, we said air is underlying the flow of dynamics and how big should the flute be when you put it underwater to have a similar creation of a frequency that would be audible. In a different medium? In a different medium, yeah, yeah, yeah. In heavy mechanics, it's much more dense. I need to figure that out. Maybe we invented a diamond whistle for this. Why not? To cut the water in the right way. Wrong with that. So, I may show what I've been working on. Please, your design is a fabulous piece of psychological seduction. I do have this name. No, no, no, no. I will not do anything. I will not present the work of my workshop. So, I call this device of the Chinese audience. It's like a handheld device. It's got some batteries in it. It's got a button for LED. So, I had a cavity so these batteries, the coils and stuff in there. Some circuitry. And you've got a cavity about here. So, Kasper was like Kasper was pitching his workshop and I was like, so, I've got a ball pen and this thing that I'm currently looking at and he was like, yeah, it's gonna be always so. And then for the sizing of this cavity, and this is where the experience comes in. Apparently you need for this, so the way this is your edge that you need to blow air onto like a hot flow of air onto the edge and the distance, in this case this will define the frequency maybe, why do we need 2 cm? But you need that similar air flow. To get it laminar. To get it one string. So the idea is to get it all here and turn it as possible off. Lock it up as hard as you can. Yes, you can. All right, so this is what I attempt to do basically by drilling into by dremeling into this plastic tube underneath I codified it because it's prettier that way. So basically, we figured we're gonna turn this part here into an edge by dremeling around like this, like this angle. Right, the right angle that we need told me. How many degrees is that? Anyways, what's the recommended sharpest possible material? Through air. We could try to add a because it's not, to be honest, it's not fully working right now. So in the process of getting it to work for the audible whistling part I can show you. The way I, because it's my first flute instrument basically I've said I want a modular design where I can play also for safety reasons, obviously. So this is the mouthpiece which has a large entry and a small exit or the other way around. So if you want to... So if you blow in here fast the flow will come out here because of the Venturi effect which accelerates it. And you do the other way around you'll slow the flow down. So let's try. So the thing is, if I look right here through my device I can just barely see the edge that I'm trying to hit. So this is the direction that my air needs to take. So now I can even see the edge through this device. So this is not working very well with your headphones. Something else in the room. So I made a bigger mouthpiece with a, which still accelerates the flow but has a bit of a broader exit. Let's see how that works. So this is a straighted line on the edge. You don't know a joint. So I'll take this straight pipe now. I just go one-to-one translation on my block. But this is, I will hit by a wall which are a mess of hope. So I don't think this is all going to work either. And that's about the screen it's going to get for now. I think this one is going to work. Demo. Okay, so what I've been thinking is either my edge isn't sharp enough. So in fact, once I dremelt it was all mold and messed up so I've been sharpening it a bit with a cutter. So I'll try to sharpen a bit more and then I'll think I'll have to play with the distance and I think the canal isn't properly pretty good so I'll start by dremeling the canal a bit cleaner in order to have a better obstruction within my acoustic canal. It's an echo chamber basically. It is called an echo chamber in that I'm building inside my resonance body. So I'll try to broaden my resonance body so that I'll have a mess of hope. Maybe I will do because I can't reach it with any instrument. More power, more better. I feel that I was kind of in the way of my stream. I think I've freed up some of the obstruction in the microscope. This would be a brilliant use for a USB Microscope. You can actually look at the very, very detailed inside view of your... I need to clean up a bit more with this ball pen device which you find that in and it's good for pipe debugging. So whenever you have some you can try to force your way through it with the frequencies. If there was a frequency at this point. I think there's a workable way to push the button to get that any way sound. It actually works better if I blow it in here which is pointy. There's an arm flute, what's that called? Yeah, you hit it at the... What's the image where the water does something out? What do you mean, but I forgot the word? It's a weird work. Yeah, anyway, maybe somebody can put it in the cat. So what else have you got? I'm kind of sad about my pipe not working yet so I'll try to destroy something else in the meantime. Our work on it was on it and we see challenges here on the same workshop in this sense. It's visualization of a data structure you saw our presentation earlier yesterday sociologist, data scientist 3D prints of data models I think might make for a good pipe maybe anything can make for a good pipe recording through the map. I don't think it works, maybe even this way is here. I think there is a machine inside which is usually your computer program does for you. Let's have a look inside of the data structure of course if you're wondering about head you might also be used the right tool for the job which might be a side cutter in this case. Turns out it's a dremel. Inside the data structure now I can feel the various layers of honeycomb the access to the data structure the data view so we caught the first clips of the data here there you go it's a bit messed up by the dremel because the way I run it too quickly it tends to melt the feel a bit so everything is a bit would you like to have a look at the data structure what we can do from an acoustic point of view about this? I think you should get it all the way through and got the same edge right here and cut up the top of the data and then blow through it let's cut the top off first yeah I would say make it maybe the dremel or with the yeah I actually like it come on do it with the cutter it's all working is it clean and cut if I just go like it's a model world without the top off and you say so our edge this is important because we need to yeah I think you have this prototype designed from earlier ah now it's an easy work because you basically cut a pipe you just need to do this cut exactly but this is a pipe if you look at it you want me to do this but this is a swing one to swing it around yeah be careful yeah the small one I might want to hold on to it because I'm going at high velocity is this going to hold ah it's 4G 5G what's your hand what's your arm it's hurting I hit it already my knee with it I don't have much space I would like a 3 minute diameter which makes it easier definitely but then you have to do it somewhere do you want to try this one can you try this one oh actually this one that looks like the one for me let's try it this way we can also swing it this way what are these called swinging sound I call them omniflux I just wrote you could have told me that the lanyard the safety before your wrist does the lanyard I'm not of the safety type of guys I'm more of the riskier I think I've got a good one here oh it's nice because it also it's around its axis what's a pretty what's a pretty noise oh it's good stuff let me get another one the dog one I really like the one I'd like one to drop the one you like one to return one to plant one to lassie let me do this one and you take the other one I can't really take mine that was nice and organic is this easy to play it's not that easy to play no you have to challenge accepted this one or that one yeah that one is easy to play yeah you have to put your mouth over it no this one this one is easy this one let's try this moisture hot glue so I just got it's very moist so it's slippery let me just get into the position I'll be with you in 20 seconds is this our finishing performance yes yes this is the end what's the how many minutes coming by should I have brought my karaoke mic what you feel comfortable with you can also make an option if you like it's probably safer otherwise it might fly as you prefer anyway what are we playing we are 7 minutes playing exactly Beethoven for Purists the fourth I guess the flute concert okay I think everybody knows what we're talking about we definitely know what we're doing if we're coming it's happening right online
