 I am very excited to present our next talk for this evening. Very interesting talk, as you can tell. This project was conceived in our local Tel Aviv hacker slash maker space, together with the Shinkal College in Tel Aviv. So I will pass on the microphone now to Denise Akerra. Yeah, hi. And Jaira Sheff and Zolma Sekofera, please give them a big round of applause for this talk. Hi, everyone. My name is Denise, and I'll try to introduce what's going to happen here. We'll have something of a cooking show or a live demo, and we will switch between the presentation explaining what electrolycables, we changed the name as you noticed, are in between what the guys will do here. Basically they'll try to make this candy slice, and I'm very curious how it will go. So what is the open source hardware for smart candies, and how we connected all these funny uses of candies, which is about canned bitcoin, and you will see internet of candies. So the way we will continue, I'll introduce first something about us, why we are doing this, then I'll explain what will happen during the live demo, and then I'll explain why we are doing it. So in the first part, what's going to happen here, Zohar is creating a mold for the candy. That means it's preparing the shape of the candy. So during the workshops, we usually let people make their own molds and decide on the shape of their candies. But here we will use few of our latest experiment, which is the bitcoin mold, basically, and Immanuel Kant's hat, and we'll explain why. Do you want to say something about the mold? Yeah, basically we are using like an acetic silicone, which is like acetic acid, that's it on, like usually people have this mistake. And it's like actually food grade, you can cook food in it. So we mix the acetic silicone with cornflour, cornstarch, as you know it, at your country. So for first, I've put like the cornstarch on this bowl, I can see the camera is over here. Okay, anyway, I'm putting some cornstarch inside the bowl and then I take out the silicone just on it. Yeah, we got like 10 minutes of like work time actually, so I'll put like some gloves where are the gloves. I think there was some interesting thing about the silicone, you said that people should use not the common one, but some cheaper ones. Yeah, this is the cheapest one, when you go to a cornstarch, I want one that smells like vinegar. Yeah, it's like 100% silicone and acetic acid. Oh shit, okay. Okay, while he's preparing the mold, I'll tell you something about us and why we're obsessing over it. So first I'll introduce you here, he's actually the real, what can I call him like a candy fanatic, and what you're seeing in the background is his collection of Japanese candies. He has this guy from Japan who sends him curated candies every month, and then he shows these are like the leftovers from the candies basically, and this is an example of such like Japanese candy that's probably inspired a year in this effort. Then there is Zohar, who is just making the mold now, and Zohar is really interested and he works a lot with flexible circuits, so you'll see some interesting things about the circuits inside these candies that are based on these experiments with different like flexible materials, and what I can say about Zohar, he's a real connoisseur and a very good cook, so it's interesting that he's making the candies. Yeah, actually this silicone has got this like steam of acid, like acidic, like acetic acid, so you get some kind of smelly, you know, but it's going away after a few days. So I'm kind of choking in here, but it's okay, I'm used to it. Okay, so something about me, I'm the real sugar of folk in this group. I hate sugar, I believe in all the conspiracies around sugar, that it causes cancer, that it's horrible, and I'm a bit terrified of this, and a place where you would normally find me would be the place with jars, so if I can ask to switch to the presentation for a moment, because this is fascinating, yes, that's me, and my favorite activity, which is wild fermentation, so I'm interested in, I do these hunts for wild lactic bacteria, lately it was in carob trees this summer, so I experiment with healthy stuff normally, I'll explain how I got in contact with them. So this is the kitchen and the hardware studio where all this miracle of smart candy happens, these are the ingredients, these are some of the components, and this is how it usually looks like, it's very messy as you can see, this is just one of the workshops in our place, this was the summer in Slovenia at the PIF camp, this is the usual atmosphere, people soldering, making the candy, and then maybe this is the interesting thing, Zohar actually made a fan sign related to smart candies where you can read how to make them and absorb the whole culture around it, do you want to say something about the fan sign? Actually it's like instructions for the kids of the workshop, it's like step by step, like instructions, and a little bit more, you can say. What's interesting about these fansigns, Zohar does all the culture of fansigns a bit low-tech and one of his ideas is not to tell everything, the fansigns have a special bond with the player that uses them, and it stops you, it even obstructs you from doing the things, so you get it to work, and we have a good ratio, yesterday we had an amazing workshop. Maybe we need a camera now, something interesting is happening on the table, it's basically just... Yeah, I'm actually making the model, I'm actually making the shape of this mold, so we printed like a bitcoin and like Immanuel Kant's head, so now I'm just tucking it inside the silicone, you know, push it like around it. So the bitcoin is made with an open scud, I think? No, actually fused, fused. And then printed, and basically you can take any object and do what you want. Okay, I'll switch back to the presentation and explain a bit the process, so what will happen after the molds? So after you make a mold, and actually this is the second part, because the more important part is the soldering part, and I think you will show more about the process and the components that you use in different circuits, and explain there are three or four interesting circuits here. Actually, a part of it, a part of the circuit is involved with soldering, but the other part is kind of conductive stickers and all of like flexible conductive materials, so it's not all about soldering. Okay, experiments with flexible circuits and materials, conductive, flexible conductive materials, and this is like some images of that process. Then comes the critical moment where we are still struggling, which is the cooking of the corn syrup, it's kind of a very violent chemical reaction I have to say, watching it. And then comes the most interesting part, is where you cut the circuits into the candy, and then you have the candy, the smart candy, and what you do after, you test the circuits and you taste it. So what is happening now? I'm just cleaning a little bit, so I'm moving to the electronics now. So in the next stage, what will happen on the live demo is they'll start cooking the corn syrup, a year will cook the corn syrup and prepare the material for casting the circuits, while Zohar will prepare some of the circuits. Am I right? Yeah, this basically, I'm starting to work on the sugar syrup, it's basically that's the instructions, in grams, 270 grams of sugar, 130 grams of syrup and 90 grams, milligrams of water. The syrup is used to stop the sugar from crystallizing, it's an inhibitor. So this is going to stay here and we have the sugar, now I'm going to take my pot and I'm going to pour 90, wait for this, I'm going to pour 90 milliliters to the turn. I'm going to prepare myself for the soldering stuff. Today we didn't have a good sugar day, you have sugar days, and yesterday was a great sugar day, today we completely messed up, so wish me luck. Something that... Where is the Chinese? Okay, so the best thing to use for sugar, stirring is this guy, and now I need to start adding the sugar. Now waiting for the solution to get a bit hot, we're using an inductive plate, very good source of heat. Okay, so if I would just leave this thing, it will just become caramel and when I add the glucose, the corn syrup, it will stop this process, then it's back to you. Okay, do you want to say something now about the circuits or in a minute? Sorry, this is the fan sign. So the whole thing, from what I see about cooking the corn syrup is the white caramelization, so you really have to be careful with the temperature and follow it exactly. I prepared something on why we are doing it, or I tried to observe why they're doing and I'll explain my interest in these cookies. First of all, the smart candies or these electro-addable, electrolycable, I don't think there are another gustatory technology and interface. So we are not really interested, or I think Zohar a bit is, but I'm not, into this multimodal, synesthetic experience of using your tongue in a new way and I don't know tricking your tongue to experience taste, which is not there. So I don't think this is another digital lollipop that tries to trick you, to heal you from your addictions or I don't know, give you like a cheap food that you can eat with Soylent and so on. So what I think it is, it is a continuation of an experiment that we were told that happened here last year. So we really like these edible soft robotics experiments that Kerry loved it, so it's a bit in that way and this is something I need some help from your side. I think it's basically a hardware fetishist lollipops. It's something about, we love circuits and we want to link them and it's part of a project that Zohar and you are doing for a long time and it's called Idiots. Can you tell us something about the Idiots? The IoT or the lab itself. Idiots, whatever it is. Actually it started like four years ago with this IoT for Idiots. Yeah, you see the violence. It was like this workshop about startup, you know, IoT startup and stuff and we had to make like a platform for people that doesn't know anything. So we made this box that you can connect one sensor and control it by a smarter phone application and control it by natural language, like control if I pass the threshold, so light me up the output of the box. We had AC and DC outputs and you can connect one sensor as you like. It's all very old news so it's not relevant anymore. So we are over the Idiots and now into this sugar addiction. So I'll show another slide for a moment if I can get back the presentation. Yeah, I'm starting with the PCB of the candy. Do you want to show something from you now or can I continue, Zohar? If you'd like to. I have something. Finally, why I'm hanging out as a sugar of folk with these candy addicts here, basically for me these lollipops are something of a philosophical prop. I'm looking into how philosophy can use prototypes and I'm thinking can leaking basically teach you philosophy and my idea is that it can basically, that maybe by leaking we can leak a concept so I picked up Kant because he is part of this long tradition between empiricism and rationalism and these discussions in European philosophy about enjoyment and cognition. So this relation between rationality and senses. So I think the lollipop by leaking it and seeing the circuit inside and seeing how it works and seeing like the connection between electricity and your senses. You can achieve something that Kant was trying to say with this principle that basically reason without senses is empty but senses without reason are blind basically. So I actually that figure of Kant in this project is something I asked him to do for me and I believe with this lollipop in the form of Kant's head we can change the bad reputation of tasting and leaking. In philosophy they're considered appetitive low senses, they're beastly inferior in need of control and they're basically enemy of philosophy. So I think these lollipops can reveal the conditions of possibility of our senses, it's something that doesn't satisfy your hunger, it keeps you uncertain if it nourishes you or poisons you, it strips you into this like circuit basically and reveals the possibility of all your experiences which is your physiology but also this electricity that goes behind it. So we have something happening on the table, I'll ask the camera to show something. Okay so you can start seeing that the bubbles are getting slower that means the water is evaporating very fast now, the glucose is just trying to catch up with the sugar and at 146 degrees we have to shut this thing down for two minutes and let it cool and then we'll add the water, the taste if we want to. So ideally you have to have the circuits prepared so you can just pour this disgusting mess of sugar over it but here we will cheat it a bit while Zohar is soldering and making such circuit, can we move here a year or you want to show it? So here what type of circuit are you preparing here? I am making the basically the circuit it's based on the lecometer circuit, it's been used like in Ratch labs and so it's a behavioral research, it's very simple like resistive touch circuit that consists like from your finger or your tongue and your hand, you know your body and one MOSFET transistor and a lead for output or some other stuff and battery so it's completely like... We've been using this circuit for the last four years in most of our work, we can really milk this guy out, it's usually used in psychological behaviors, experiments with mice if they go and the end of the, that's basically our way to communicate with animals in psychological experiments. Like one new one. Okay, I'm getting ready for pouring the sugar. Where are the circuits you want to use? So we're going to use pre-made circuits. Zohar, can you use it? Zohar, can you continue? No, we're at 136, the rise is very high now, there was a lot like 120, it just catches on you, if I don't get it on time it will caramelize and stuff will get really messy, 146, 142. Actually we have here like prepared ones, so we'll take out, now we can see it's taking like 10 minutes to get it dry, like for the mold, as you see now, you can easily take it out, it's pretty fine mold, you know, very cheap DIY mold, which is actually not FDA food grade, but you know, you can, look, we don't care about it, you know, it's not going to be like a shelf product soon, or in the medical industry, or something like that. Actually, I made it a bit thin, so I have like all in the nose, but I guess it will be fine. You messed up my philosopher. Yeah, I punched his nose. Now the bubbles are getting out of the, we're not putting the flavors before the thing cools down to 120, then you can start mixing them. Actually we don't usually mix colors, it's just nice and has a golden thing going on just as well, but it doesn't taste as well. Yeah, I just want to solder some, okay, so now I'm just pouring some drops, this guy is a watermelon, our favorite, and wait a second before you put it in the mold. Now because of the temperature difference, it gathers a bit more air inside. I guess you also have to wait till the bubbles settle a bit, yeah, you don't want too many bubbles in the candy. Is it, or how do you deal with the bubbles? The bubbles will just go away very quickly. This is not something you need with vacuum to get them out, they just like do their thing, but it's really, it's every sugar day, it's a different day, some days it's just everything where it goes wrong, it depends on the humidity, and you even have to calibrate your temperature probe, like it depends on what we are when we boil in piff, it's quite high, so it takes the water at a different temperature to boil. Okay, I'll switch back to my stuff, because it seems like you're still doing something there. Yeah, I'm kind of, I'll just, if I can ask for the presentation for a few minutes, I'll sneak in, so this is the candy I'm interested in, it's the head of Kant, and you will see it, it's doing some interesting things, it teaches you disinterested pleasure, discovered by your intellect, so you lick it and you understand how something works, you see the contraption that triggers your senses, that's the ultimate Kant actually, and you know, in order to get this head, I had to go, I think it's the Bodin Museum, it's this famous Berlin Museum, and I was actually scanning him in order to get this, anyway, I think Kant was very wrong about his critiques, he was interested in pure reason, and also in practical reason, but what he didn't write is something I believe sugar represents, and also lately Bitcoin, it is this thing that drives all our addictions, it is basically the speculative reason, an investment, and sugar from which this candy is 98% is basically just that, it's something that created the slave trade, it created the biggest demographic changes in the world, and I think we need basically a critique of the speculative reason, so it's also, sugar is an interesting example of post-carcity, basically from something that was a luxury product, it became a cheap addiction, so what is the new sugar, it's a Bitcoin, and we are switching back so they'll show what's going on here, okay, the sugar is in a walking state, it's very hot, in a minute we can actually even touch it and mold it, but currently it's very hot, and what we're gonna do is we're gonna pour it into the mold, Zora made the circuits, and now we're gonna pour this, a circuit which doesn't work at the moment, but we prepare in advance some that do work, so we need something to stop the flow, oh here they are, okay, usually now when the circuits work, this thing lights up, the circuits themselves in a professional environment, they get up to 220 degrees usually in a reflow oven, so what we're doing here is not up to this spec, so it can hold the circuits, we are gonna show you now completed circuits that we did 40 minutes ago, and now we put them outside to cool a bit, and the thing is you usually take them out when you can touch it with your hand, and it feels like the same temperature, I think it's good, so let's see one that works, take one like here which is not thick, okay this guy is interesting, this one we can show it, this one has a temperature probe inside and a microcontroller, and you can actually change the temperature and the addressable LED, it's like a thermo to RGB, yeah it's a thermo candy, so this thing you can actually use for kids, but it's hot now because the sugar is still warm, so it's still red, usually it should be green, so we made all the things like one hour ago, so okay this is all, you can come and see some of the circuits or if there are some questions, do we have minutes for that? Okay this one works, okay, so first of all please give a big round of applause to Denice Adenzal for this monstrosity of a talk, and we actually have some few minutes left for questions if you have any for what's going on here, and we have, we'll start from the internet, okay the internet wants to know if you've tried to use the laboratory like heating and storing plates to make the, yeah they call it the sugar mass, actually we use like this induction stove because like induction is like special for boiling stuff, so it's very quick, it's taking like half the time, but we do it in all kinds of way, we usually don't work with laboratories, we don't have access sometimes, yeah we actually invented it in the PIF camp which is like hacking, you know, nature hacking, you know, yeah we only worked at night because the wasps furious during the day, so we walked in a tent, so that's a question from microphone number three I'm curious what program you're using for photogrammetry or 3d scanning to make your camp model, oh yeah we use a reality capture, really good, it's a professional, but they have a trial, go check it out, yeah, also open sky we like very much, it's like very nice to make like gears or like small parts, yeah another question from the internet, yeah the internet wants to know if you use lead free soldering and what about like health concerns regarding the solder embedded in the candy, oh, it might give you, you know, a not really major diarrhea, I don't know, nobody died yet till now, microphone number three, thanks for saying nobody died, can I get one of the candies, sure, come and pick it up and one last question, microphone number one, yeah thanks for the talk, I have actually two questions, number one, do you have a recipe also for fructose intolerant people, and question number two, do you plan other philosophers, for example, island warts, wow, why island warts, like I mean I'm very curious, okay, she's the philosopher, it needs to have something with sugar or senses, it has to have some, you know, connection, but I'm all open to that, so next workshop, okay thanks, okay so that's all the time we have for this talk, again a big round of applause
