 So I'm happy to introduce Dasha. She's a media artist from Canada originally, I think, and she works at Bauhaus University And she's done various exhibitions as I read in Oxford, Berlin, Montreal, right? And basically you're very famous for a lecture series called a Sideman 5000. Yeah, it's the world's oldest commercially available drum machine. That's pretty impressive. So Today she will attempt to build 20 sound generating square waves in 20 minutes. So enjoy and give a warm welcome to Dasha. Has anybody built electronics before? Has anybody built electronics in front of this many people before? Yeah, so You better be fucking nice We need some magic on the screen here. Oh my wonderful assistant here My other wonderful assistant here who I had to put a googly eyes on to make me feel safe So I am going to try to build a Series of square wave oscillators. Oh shit. Okay. I need help with time right because I'm supposed to do this in 20 minutes So even while I start here, I need some help. Who has a hand who has a phone? Here who's got a phone people? Okay, and do you have a phone that has a timer on it? You have a timer? Okay, where are my students from castle? Whoo, you guys have a job to do You have to time me you have to start 20 for 20 minutes. Okay Okay, tell me when is that fritz Okay, tell me when All you see here these capacitors that are here. Oh my god. It looks awesome Okay, I'm not These capacitors are just like what I'm I'm connecting the outputs. Okay, so just like don't think I'm cheating It's just the speakers essentially. Okay, so tell me when to go buddy Okay, shit. Okay Okay, I have some power there Don't don't forget to let to remind me to put power on the other boards. Okay Square waves are really good for your speakers Because oh at least there's some sound oh My god, please Okay, that's one square wave oscillator Okay fritz What's my time? Okay I'm still doing okay here Okay, more power is needed on this one. I'm shaking. Does anybody have any jokes? No, I'm actually like this is fucking hot. It's too much And Yeah, does anybody have any questions for me? I might take a little bit longer than expected So if we want to do question period right now, I'd be happy it takes my mind off of things We don't have questions, but we have translations available. You just need to dial AT 14 You're welcome Okay, did I get all my batteries in here yet? Do you guys like the sound of your heart? Yeah, me too. I don't know Okay, that's like kind of a promising sound who's building electronics while they're here Okay That one is not oh Or okay. Yes There's some extra stuff going on there. That sounds cool. I Sometimes I don't always know what to expect from these things But I'm usually just happy when some sounds are being made. So it's good Do we have any Norwegians in the crowd? No people from Norway My first ever festival was pixel festival in Bergen an awesome art hacker festival Did I already say what chip I was using here? My students know Say it louder five five timer. Yeah Right Okay That's the sound of three Oscillators. We're doing okay. What time? Okay, good work. Did I already tell you about how excited I got when? To make told me that I was gonna get a headset For this performance cuz like I was really envisioning a Madonna kind of thing But it's more like it's more like this weird Ted talk thing. I don't know if you guys have ever looked at this thing I'm close. It's like really bizarre, but it seems to be working. Right, right Okay. Yeah, okay. Good. Do I have any questions yet? What are you doing? I'm building um, you know, they just do one thing they either make your speaker Cone go out or back in and I like the limitations of that. I like to think that I just need like Something that's really straightforward in and out. I have to work with the acoustics and everything to make it I should have worn nail polish If you have questions you can already line up on the microphones go ahead of people Mike Do you want to ask me about duty cycle or what? They're all different frequencies if we take a look at my little chart here I've selected a series of resistors and capacitors a frequency that makes the Oscillations go kind of slow they get faster and they scare the crap out of me more you a little bit excited Can you add some LEDs? Yes, you can because it's very versatile here. Okay. I'm stuffing LED Totally welcome Okay, what's that noise? I'll try to make some weird noise That's just the power going into the next chip and I have to keep like testing their temperature Just to see if they're getting really hot because if I cross-wire them they can explode which is also kind of cool But I've never sustained an injury so far Injury was I was wearing like these jeggings while I was soldering once The solder fell onto my leg and like burn through my crappy little jeggings. You guys know what jeggings are. Are you bored yet? Are you bored? Okay Okay, good thing about this guy. Are you still okay with answering questions? Yeah How do you protect the output from completely blowing up something? I don't It's hard to do it. Good insurance. I need to go fast. Just pretend and like cheer me on, right? Okay Stand here. Yeah, I think wait a second. So you've already taken questions, right? Taking questions You've already taken you've already taken questions. I mean I've taken questions and no no no if you want it You could use your question time and finish the last two. Okay, great show I think you you probably just want to leave it at that right drink a beer, okay? I gotta make sure it doesn't yeah, okay. Yay. Thank you excellent That was excellent audience participation. I have to say so we'll be back with the next talk in 15 minutes Until then have a beer
