 Hi there, my name is Mike. I'm from Goliath. We're a device management cloud and we're built on top of Zephyr. Zephyr is an open-source real-time operating system that's managed by the Linux Foundation. We make it really easy for you to connect your Internet of Things devices and make sure that they're secure by default. So each device is going to have an encrypted channel back to the Goliath servers. This demo that we have right here, if you imagine like a greenhouse that's using both natural sunlight and augmented light, you want to be as efficient as possible so we have a light sensor here that's going to measure and try to hit an exact target. If it gets cloudy outside, our cloud will tell the light to get turned on and make it more efficient to hit your yields and your harvesting deadlines on time. Of course this is using Wi-Fi and Ethernet. These might not be the best technologies in your greenhouse situation, but we have another demo here that's based on open thread. If you think about like Bluetooth as a radio technology, this is similar, but it's actually the thread is the radio technology. All of these devices connect to each other. They make a mesh network and it's self-organizing, self-healing, so if nodes are added to or missing from it, you'll see them. And there's an accelerometer in here so I can press a button and you'll see the accelerometer got a change. This is actually going from the device through what's called a border router, so the border router itself has an Internet connection. It goes up to the Goliath servers, the data gets stored there, and then we see on our visualization platform it come here. Really the future is all about connecting more and more devices. We make it easy to manage those largely to devices, including the ability to update the firmware that's running on them. So if you have a security vulnerability or you need a feature or anything like that, Goliath manages a way to upload your new compiled firmware, have it downloaded to the device, it'll check the signature to make sure that it is what's expected and who it's from, and you'll have all the features that you were looking for. So how big is Goliath? There's ten people working in Goliath right now, about a two-year-old startup, and we find that we're a translation layer between the people that are doing the low-level embedded and the cloud teams. Since we're built on top of Zephyr, we're hardware agnostic, so anyone that's doing embedded engineering can build with Goliath. And where are you based? We're actually all remote, remote first, and so we have members in the US, in Brazil, in Poland. So yeah, we work all over the place. And how is it to work on the Zephyr ecosystem? I think that there is a learning curve, so if you're first starting, just know there's going to be a little bit of effort to see how things are done, but once you get going it's really easy. For instance, talk about the last piece of the demo. Yeah, this is an E-Ink display, so currently it just turned on. It needs to get connected to the Wi-Fi network that's hooked underneath the... was it on? Yeah. It's a demo thing. Yeah, demo culture. Yeah, there it goes. Okay, so now basically it's going to update with my personal information first, company logo, my title of course, got some blinky lights here, but basically this is also a Zephyr based device running with an ESP32 S2 on the back, talking through a Wi-Fi device that's underneath the desk, and it's talking up to the Goliath servers, and it's listening for all the data much like the dashboard that Mike showed. And so currently it's just showing this single view. We can also do a look at the data coming off the blue demo, so Mike wrote some code to redraw the screen and get the live data that's showing off the blue demo. Did you explain the blue demo or no? So we're getting that coming off. If we look at the green demo, the green house demo that we were showing before, you can see the live light intensity value. You can see the live light intensity value, the target value that it's looking for, and then the brightness of the lamp between 0 and 255. You can also do things like the quality of light, so it reads out like red, green, and blue on the light. And the final one is like these little dope sensors. It should say normal for all three of them because they're upright right now, but if someone were to tip over your materials and we press it again, then we can read it out again and we should see one of them is now inverted. So we can do live monitoring on our name tags at the conference, which is the time fine. Nice. How soon does the conference have this? How soon does the conference have this? Oh wait, like it's a conference badge? You know, Mike and I used to go to DevCon a lot and we love the badge life community. We hope that other conferences like this would bring that sort of thing in. But we do not see that anytime soon at the embedded world, but there's a lot of other great stuff to see and get at embedded world. But if you're looking to try out devices like this, you can go to GLAC.io. We have a dev tier that has the first 50 devices without paying anything. So you can play around with it, get your own stuff, talk into the cloud and back and we're always available to chat about it. This is actually an Adafruit dev board. So this is a $35 dev board from Adafruit. It's got e-ink and sensors and ESP32. We use it for training as well. So if you get a training.goliath that I can try out Goliath and follow along with tutorials and Zephyr. And what's your discussions happening here at the embedded world? What are people talking to you about? Yeah, I think a huge number of people are looking for over-the-air update for their devices. So when you have things throughout in the field and you can't get to them, you need a way to update the software and we specialize in that. The other thing is a ton of people see that Google's technology called Matter is coming next year and Matter is built on top of Thread as a transportation layer. We also specialize in doing thread communications. That's what these red devices are talking on the thread platform. So we've heard a ton of people asking about that as well. What is the matter? What is the matter? What is the matter? Oh, there's a lot of things that matter in these days. Matter is a software layer from the CSA, formerly the ZigBee Alliance. And basically that's going to allow interoperability in the smart home. So if you had like a Google light switch and an Apple light bulb, assuming Apple would ever make a light bulb, in the past they weren't able to talk because the software management layer was different. Once Matter comes out, basically those will be able to talk. The Google light switch will know how to talk to an Apple light bulb because of the software management layer. But those will all be built on top of other technologies like Wi-Fi or Thread or Ethernet. And basically it'll allow more interactivity, interoperability, that sort of thing. We're personally interested, I'm personally interested in the Thread layer, especially because you don't necessarily need that interoperability, but you could take Thread and put it into an industrial market as well, and have the meshing and the other IPv6 characteristics of a Thread node that will then get passed all the way back up to the network and be controlled by the lab. Do you know Rudy from Espresso? Not Rudy, we know. Oh, hi Rudy. Yeah, how are you doing? We know Sprite from Espresso. We're using your stuff, our smart lamps running Espresso as well. That's right. It's a great technology. Yeah, we love Espresso. So there's a bunch of Espresso in there? Yeah, in the badges and also in the smart lamp. These devices are running NRF Nordic semiconductor with the Ethernet, but I've actually prototyped them with Espresso and Wi-Fi because it's easy. One of the places that Zephyr really shines is that your C code is completely separate from the hardware that you've chosen. And so it kind of extracts it away, makes it possible to like upgrade within the same chip family or even switch between vendors or switch between manufacturers of sensors.
