 Day zero, traveler Aki. I somehow came here on purpose, seeking the unknown, the chaos and surprises. From the moment on I arrived, everything happening was a surprise, yet strangely familiar. Not only to me, but to all the travelers gathering here. This logbook is my attempt to preserve the knowledge against and unhinged it from time itself. I do not know most travelers here yet. As always when I leave the old world and enter places like this one, the interactions are heartfelt, respectful and filled with genuine interest, particularly towards our distinctive differences. As my free thoughts, wild ideas and my ways move and name myself have not attracted any negative attention, I can spend most of my time here interacting with other travelers and the environment. And these interactions are enriching in many, many different ways as the travelers wear a cardio around their wrists. Cardio connects to each other, they call it cardio-cardio, as far as they know or think. Everything all cardio show is a special time we all share here. It started with an opening talk, some travelers prepared and it counts all the ongoing hours since then. I do not know if it will stop when the last workshop here is finished or if it's new time that started will go on. Welcome to the CCC camp batch talk from the CCC camp batch team. So you might have been wondering what the strange audio was all about. The following happened. You may remember Radio and we played around with Radio and then tried, as you can see here, I did not do that, I just tell you how it happened. You can click on a data logger on the radio and then in between the reception and the data logger set up a time delay. Now we tried to play around with this time delay a little bit and then we set it to minus two and a half million and what then happened is that we started to receive really strange sounds. And then we have a little bit of crypto, quasi future crypto that decides what you just heard. So that's why this noise and so on. And we have been looking around for a long time what it could have been or what it could have been and found out this is a message from the future and not just any future, it's a message from the CCC camp 2019. So this traveler archie that we just, or the one we just heard, reported from day zero. Yes, we're leaving from the camp. And we have now found out that we somehow have these messages from the future and that something has been given, what is called cardio and what is carried around a arm or so. And we assume that the badge has been, has been, has been. Yes. So far, the knowledge has been found and then we have found that we of course have to take care of that this badge will have existed because otherwise we of course solve a paradox in the space-time continuum. So if we don't take care of that this badge has been given, then we will also not be able to receive the messages. And you can imagine what this will solve for a traveler. So far, we have brought together a research group and started to find out because of these locks. We have held several more, some of which will also be heard and we assume that more will come because of these locks to reconstruct what this cardio will have been. Thank you. First of all, we dealt with it. What do we even know about this Cardio badge? And that was the first thing we heard about it. Well, well, it's probably related to the wrist, you can wear it. So we have in our research group decided on how to somehow build it so that you can wear it and have very different research approaches. The first research approach was that we tried to build the smallest possible device that you can wear on your wrist. You can see that it is a design with a board with four different designs and the question is how do you get it as small as possible? And accordingly, we have ideas that you potentially stick the display on the battery and then, accordingly, to get it as small as possible with a plate. So that we can see such a large comparison, how that could have been, we have a hand model there that briefly presents us. This is an actual size. So you would wear it on your wrist. Of course, it is a really simple prototype that simply shows the plate and shows the wrist and we can estimate that. Okay, that would probably be the lower possible limit. The highest possible limit was a completely different approach. What would you like to wear on your wrist? We have that once again with a human arm in the large comparison here. So that would be the wooden model for the largest possible plate that we could imagine that you would like to wear on your wrist. Both suggestions are in line with the size of each other. There is another research team that deals with it. How do you wear it on your wrist? There are actually a few problems that you think about. For example, that you don't necessarily want to wear a plate directly on your wrist. Allergies, sweating, all kinds of things are of course uncomfortable. But you probably won't have a chance to have a house designed until then to be built. And accordingly, we thought about how can you get it so that the wrist can solve it cleanly. This is a design for a wristband. On the left you can see the plate on top. On the right you can see the possible attachment. It is about a fast-forward, the connection that is corresponding to the size. Hopefully that will be made more professional. Fortunately, we were able to receive more things. Day 1, Traveler Moon. So far I find out that when I move, cardio moves. As if it had its own orientation. Just now I saw someone performing something that seemed like healing or measuring their blood. But that's not all. Today I discovered that my cardio can pick up information about people's skills in my surroundings and led me to a person with a crazy hat that really knew a thing or two about call smithing. I actually found a way to transferred my own interest to the cardio and from that point on it started to oscillate softly when picking up similar interest in my vicinity. That's how I found a camp of hedonist creatures that knew more about security that I could have imagined. I don't know if it picks up brain waves or if it has to do with blue glow or what else is going on. But at least I learned again that my first impressions can be deceptive. The first thing we see is that we hear from people who keep it in the air and then do things or alternatively, we heard from people who seem to have used it to navigate and find out where they went and similar things. So we thought okay, there's probably a compass in there and a acceleration sensor, maybe even a mirror. But that's not exactly what we're talking about. We thought let's put a few of them in. It looks as if the device could interact with the electromagnetic spectrum or could have. Mostly in the 2.4 Gigahertz spectrum, pulsed electromagnetic radiation with today's technology probably Bluetooth Low Energy. Maybe it could also be other modes. We are not quite sure yet, but we will see how we can approach it as much as possible. It looks as if it could have floating point operations and several at the same time. It seems to be high technology, but in the meantime we have dual core and as many core processors. You can imagine that. Especially, we have reports of people who say that it will have things, low electrical voltage, apparently it will also have resistance. We are not yet quite sure what that should mean, but maybe people have in the future also found funny things that may have the resistance of living beings. If you combine such things with the spectral properties of blood, the doctors say you can find interesting things there. We think that the people in the future have already used this to possibly measure blood pressure or something similar. Surely there will be a war in the future about editors. To not create confusion and not bring the wrong people together, the doctors have said who will use which editor. And with mechanical vibrations, with a display, possibly with a small light show, we are sure that in the future funny things have been made. I hope that we can approach them as soon as possible, because we want to keep the space-time-continuation. Accordingly, we have seen a lot of LEDs so that the future becomes colorful and people find each other when they hold their arms in the air. Maybe you have a persistence-officer or something similar. I think the future becomes colorful. And out of all these technical things, we have a distilled design and we hope that the future will be well-approximated. Yes, we are now presenting our current research. We have imagined that all these components that were used there would not fit on a board, would have fit. That is why there will be two boards and the lower board will contain many components, including the CPU and the components that have just been named. The logs also spoke of something fluffy, of something metallic. And we have continued to research about this size will have this thing because as an armrest and as an armrest watch it has to be compact. And here are the first reconstructions of the board. That is archaeological work, it is still not quite clear, it is still not precise but this is how this board could look like. Exactly. It should have moved, but here is a 3D model of our current research. The boards will be mounted on each other and attached with a armrest. We thought after some research that a neoprene with a Velcro on the bottom could have been quite practical. And we have also heard of expansion possibilities and in this way could have been attached to the armrest with a steering wheel with steering threads. Exactly. And now we continue with the reconstructed future timeline. The future is soon. We have about four months to save the space-time continuum. And currently we are at a stand that has a empty board and with components that are just unwilling to use their hands. We currently have a deadline in May. We will decorate our board and move it to life. We will continue with the time continuum and build 20 prototypes in the Federal Republic to see how many people can implement all the good things that have happened in the camp. And implement it. On June 17th is our deadline for the final order of the board. Then we know exactly how it will look because then nothing can change. If it's not that, then the world has to go down because the continuum is broken. It has been shown four years ago. Flashing is great on the camp. We have we can reward many people in the current plan, so August 19th, deadline for the company. It's a tricky project, but we have the order to implement it, otherwise it won't happen. We will continue with an introduction of LOX. IOT With my cardio I can always see one shared time that counts every hour we are here in this community in a still very linear way. But besides this, I have my own input-output time. As for me, it's totally different to spend my time with my mind in virtual space or with my body in physical space. I program my cardio to a time cycle that takes my movement input and goes on with my time cycle if I physically move around. With my ongoing time colors of my cardio, general lead slowly shifts from light yellow to violet. Today I met a traveler that had an interesting perspective on his own rhythm. Because they feel insecure about the amount of time they want to spend on their own to rest, they program their cardio that goes on to the next unit of time when they shake their cardio heavily. So they decided to shake their arm for every moment they experienced and aimed to rest every 10 moments for some time in camp mode. I hope to meet them again to see how he feels with his time. I just loaded a pulse-input time cycle in a village where all local travelers shared this pulse time. I will join into this time now. It is an interesting new way of relating my time cycle to my physical being. Most villages have a sort of loading and connection stations so each traveler can come with their cardio and get new and different times loadables, jokes and they're even in some kind of dictionary. There is some kind of a dictionary thing. These stations are called Day 1, Traveler Aki. Since this morning my view on cardio changed again and I found out about the possibilities of communication through color. Not only can one sync with other travelers by showing the same blinking theme while holding cardio high above one's head, there are also free colors that have a special meaning for everyone here. Free lights framed by a yellow, a blue and a green circle are used to communicate one's scope of interaction with the world. If a yellow light is active travelers somehow seem to be in a wild adventure mode or in submission. They call it the chaos light. The blue one seems to stand for a general open and communicative mode. I saw travelers starting conversations a lot of blue light at others. The green one is a sign for a traveler to be in so-called camp mode which to me means to do self-care. To not be visible for other travelers because I'm fine with being for myself. Since I started to use this interaction experiencing the blue mode is the most exciting to me because I'm still not used to people just starting conversations with me and I'm enjoying it a lot. I appreciate the comfort that comes with activating the green light. I can be totally by myself although I'm floating around. It feels like a lot of different perspectives were included in designing all those interactions for cardio. I wish I knew more about the travelers that developed all this. We are a team of futurological archaeologists and a lot has to be found out so we can avoid a paradox and since you have all called to become archaeologists of the future also to search for interactions, to search for loadables and to see what could be the right villages. And of course it is also important that the individual villages maybe also after they know their own villages should be the ones who can search for their own village after the interactions because only then can we make sure that all camp villages also have had interactions. Otherwise there is the core team that I have dealt with a lot of things but our logs have also shown other things and on the one hand this batch with the design of the camps together have been included and we don't have any experts and that's why we are still looking for experts who can deal with it how this batch could have been and also how the communication could have been. In addition, we have also looked into the logs if there were any problems with the management but it didn't work we believe we need special attention for UIUX so if there are experts who want to deal with it how it could have been it would be welcome. It looks similar for Bluetooth Low Energy iOS Development so we have found out that it has been interacted with Android and it will be with iOS it will also be happening and another interesting point is that ethics and biopolitics also come into the logs and also there we want to start our own research group that deals with ethics and biopolitics of such a device and finally the metal parts will also have to be finished and also there we have no idea how it could have been I don't know therefore there are researchers welcome otherwise you can contact us either in our Batch Workshop where we can answer your questions our current research and of course we also have other contact possibilities including Twitter we are at the IRC and on Matrix and we also have a wiki where you can watch what has been found out so far thank you and now to the questions I have a few questions from the internet or specifically the batch.team team they have a few questions they asked is there a pre-event user experience so can we program apps in advance there is a toolchain emulator or something like that that we don't on the camp but at home when we can program something as far as I know it will have been given ok, no good I am not so good in German past tense as far as I can tell it will have been there ok, good and schematics based firmware will that be released I think it will have been released as soon as it has been done ok, yes and then one question schematics are already online ok, that's good and then one question for myself I saw you want to flash 5,500 batches or something 2 days before the event while at camp aren't you I have seen also some things in the past and I have also seen events where they flash the batches up front with some basic firmware and then at the camp and over the air updates so you don't have to flash them all but you can distribute it over all your users isn't that an idea or English, German, well it doesn't matter we had a good experience with the radio batch that we flashed it especially the first firmware in two ways, a really nice hammer for a beginner in electronics to get flashed to prepare the whole tool chain on the computer of course you could prepare stations where they pass after we actually have to pack them together that means we have certain plates on the one side but we also have to with all other components that you still need to assemble the batch ready pack them together we had a really good experience that we built more of a production road and it was at the camp at day minus one so many helpers and angels who wanted to help and accordingly it wasn't a problem last time and we assume that this time it wouldn't be a problem would be yes, thank you any more questions or maybe just ideas yes, good we will definitely also be a bit on Easter and people can personally talk to us and come to the conversation about how our research will continue and we are happy about everyone and everyone who likes to join us or for yourself continue to research, thank you as you can see, unfortunately this is all very small this will still be a pretty good selection we have components that you can see here this is a BGA with a 0.4mm pitch so 0.4mm distance between the balls so we will the production will start in Berlin in the beginning and there we will also have to see if this design works in the end this is something that you can't find on the market there was a lead challenge to solder you could try it the maximum you can repair is to solder the component there will be no more and we all hope that the prototype works and as soon as we have the first results and it is also the goal that we also bring that you can join and that you work actively with the company that we have a great company have great interactions and let's make a great batch I have one final question and that is after the camp user experience will there be any software support for longer term usage or is it just after the camp going to be a part of historic e-waste not to produce e-waste of course since the rocket we always figured what is something that is useful after the camp and not something else to hang around your wrist sorry, around your neck so yes there will be a useful functionality after camp that is absolutely the goal more questions have you already announced that all 3D printers people can prepare different housing designs we have this plate layout that is the lower plate it is not final there could be changes that is why the timeline mid-June is the final time for any changes on this plate we do not expect changes in this direction more interesting is the upper plate that is the camp design we have to talk a bit about the camp how early it can be published that is also a question we are not done yet with the display the display is not yet final we are looking for that the upper plate is just standing for the top plate we have a design for public with the connector and the size that you have the chance to make your own designs for the upper plate and will give the requirements because the battery is on the lower plate that you have the chance to think about your own designs to build something else there was a question have you ever thought about how efficiently it will work that is always the question what are the costs of the connector these are M2 screws with Torx T6 or T5 we will say that bring enough screws with you you can see these two metal strips if you know a manufacturer where you can let these metal strips out it is just an offer for a euro per piece with two lower screws and that gives the IKG contact you make a third contact you put a finger on it and what you can do with your hand between the light also the battery it is put on top of the upper plate and via this 30 pro link connector where you also have GPR host IQC and SBI the badge it has to be easy to do and we will bring enough screws even for those in the grass to disappear we will order a few hundred more I can only recommend a product to build a design I can only recommend to build a design that alone and then put the screws in because in practice it goes extremely wrong and the answer to the original question that I think you asked the participant screws together in the locks there is also something that is given stations to which the bands can be mounted and also extensions and maybe also delays and these things can be attached and that's why we assume that everything is well done so the prototype that was just under the camera is also screwed together with these screws and that's what I have done with my Wurstfinger and also with the tongue I had a short question you talked about it earlier with spectral measurement of blood something like that where exactly is the sensor because I see a 3D rendering no cutout on the bottom of the watch the watch has privacy features and does no measurement of SPO2 on the bottom but a finger based measurement with the finger on top red, infrared and possibly with a third EKG channel just like the demonstrated here exactly, another question you talked about blood pressure measurement but I think you mean pulse measurement or? there is the option to connect an EKG and the blood wave basically what you do is you measure the EKG and define the time when the heart beats and you see when the wave will arrive and you can draw conclusions but that is a measurement that is not absolute you have to calibrate it and then it is stable for a few weeks on a few percent that is the current research that we know but I think it is something that people have to play with if that works this sensor will also have another EKG that will probably come when you touch this SPO2 sensor the third contact for the EKG the EKG does not work on the wrist because I have to let the third information run over the heart and I do that by pressing the right hand on the bed and thus I create the third contact and then I can measure the SPO2 and then when it is calibrated even a blood pressure we have our first amazon blood pressure and we will test how well that works another assignment to the screws so if you want to have a direction to screw that you put the screws something like that there is a 3D printer proposal for reading and bring it with you ARAZIL just one more question because you have direct contact of the metal parts have you thought that you maybe take small saws alternative materials I do not know what you are planning for the metal parts but in the beginning there are still a few golden metal parts for all the allergica or else something else because this part could otherwise be for a part of the congress not to be wearable without allergic reaction we have seen stainless steel also the screws are stainless steel and these plates will be stainless steel alone to deal with this nickel problem but that is we can not I do not know if you do something for gold for those people you have to think we will definitely give out the specs that is a metal part with two stainless steel holes where the two screws go in and that will also be stainless steel and must be in grade that there is no damage I think that is the most neutral what we can choose and basically it is also without metal just that the wristband will be sewn on it then there is no danger at all and yet because the velcro is so thick and this neoprene is also possible to sew on the top therefore with the conductive thread no skin contact can be produced in this sense thank you for your attention and hope that you will also be active in the research be it to produce your own interactions be it to think with your village what exactly the context can be between the cardios and these stations at the villages or be it that you will get into the research team thank you very much and we have a workshop tomorrow at 4.30 and we are looking forward to talking about details when you get there
