 Saya akan bercakap lebih banyak tentang laporan bagi Poh Ket Sign today. Jadi, perkenalkan yang mengenai laporan bagi Poh Ket Sign ini adalah actually a small, Arduino-sized board that actually tries to simulate several scientific instruments. So, I will talk about what science instruments that it actually supports. So, a little bit history of how Poh Ket Sign lap started. So, initially it was called C-Lablet. It was actually quite bigger size, maybe about half a size of a laptop. That was the initial idea. And then, of course, that was closed source. So, we tried to actually open source Poh Ket Sign lap that came out with the first hardware. And then, of course, it came out with the first hardware. Yes, and then we created a Python desktop app with PyQT. Because, but then there's a lot of things that's broken from Python 2 upgrade to Python 3. So, we actually stopped that and we created a newer version with Electron now. And then we actually reduced the size of the Poh Ket Sign lap from that size to about the credit card size, Arduino size. And we tried to sell it on portability. So, actually, anyone can bring it outside for learning activities. Just plug it to a phone as OTG. And then, we have a web app subsequently. This is a part of future roadmap, which is actually still in planning. So, this is how you see it. This is the original C-Lablet. This is quite zoom-in size. This is the original version. And then, we have our Uno form. This is actually double-sided. The cost of this is actually higher than the current one because it's printed on both sides. And then, of course, this is the final one. So, it's about this size, I think. So, I think I'll just pass it around. Y'all want to have a look. Y'all can have a look. So, you actually connect solder on a ESP8266 at the back. So, you have a Wi-Fi support. Or you actually can attach a Bluetooth module of HC05 at the front. And of course, we keep the programmer ports open. So, it's running on PIC24. So, let's say we have a new firmware with more functions. So, you can actually just flash it with the PIC kit. And then, you can have the new functions. So, yes, how do we use this? So, you can use it through our desktop app or Android app. So, initially, the desktop app was only on the Linux because it was built on Python, of course. And then subsequently, we worked with schools in Singapore. And most of them are using Windows. So, then we started to think how are we going to make the desktop app multiplatform. And that's why we came up with ElectronJS. Ya, but anyway, just to roughly show you, these are some of the libraries that we have. The Python library is just a very basic one. It talks to the board through the terminal with Linux or terminal. Then we have desktop, Android, and firmware. All these are open source. Even the schematic is also open source as well. So, this is how our Android app looks like. This is actually an older version of the Pocket Science Lab. The newer one doesn't look like this. The pin slightly changed. You'll see that as the old one, it actually has what's that called a potential meter. That's actually to adjust for volume and things like that. So, anyway, things have slightly changed now. Okay, so anyway, this is like an oscilloscope and some power source. You don't need external power source to actually power the board. Everything is just powered through a micro-USB from your phone, and that's sufficient. And then we have multi-meter wave generator. The basic few instruments that you always actually use in labs. And then, of course, to make a user experience better, we actually, on each instrument, we did a guide so you can actually just swipe up on the app and see how do you actually use the app. Yep, and where to plug it and things like that. And then, of course, this is the new desktop app. I can't see this clearly. So, it's actually built with Node.js and Electron. Yeah, so our focus is actually just on the basic functions of the Android app just to port over yet. So, we have these are some of the ones. And then, we recently actually came out of a robotic arm control UI. So, actually, we actually made PS Lab to control some arms previously at one of our hackatons in Vietnam with partnership with UNESCO. Okay, so these are some of the hardware specs. Yeah, I'm more into the software side, but for those who are into hardware, you can actually look at this. Of course, you can find this as well on our GitHub page or our website as well. We actually put it up there. So, yeah, some more waveforms, PWMs. All right. So, we have a measurement. So, you have multimeters and stuff, things like that. Of course, one of the functions that we built on now is recording. So, while you're actually taking reading, you actually could record the statistics and export it at CSV together with the coordinates. So, our idea was actually to make an online platform for different people to actually share their data, let's say weather data. So, sometimes some of the sources, they say official sources, the data actually are not as accurate. It might not be the fact. So, let's say they have this term, PSI meter in the middle of the city. So, that reads maybe of 80 PSI, but maybe it's outskirt of Bangkok could be much lower, but you are taking 80 PSI. So, by having PSLAPs different people, you actually can have more accurate data. So anyway, I was also responsible for the production of PSLAP. So, I went to China. So, this is the batch I support now. Yeah, somewhere. So, this I went to China and produce. Of course, there's many things on production. If you want to ask me, you can ask me after that. And yeah, these are some of the stuff. Of course, there's more. Yeah. I think the most important one is actually the first line. Yeah. There are some manufacturers who say it's very cheap, but they don't tell you the condition of it. Yeah. And then of course, I'm more responsible for Singapore operations. Of course, we do this in Vietnam schools and some of the hackerspace in Berlin as well. So, this is some activities here. Of course, we will be contacting more working with schools to understand their curriculum and how to integrate this with their syllabus so that they can actually use it to make learning instead of just stuck in classroom but can go and have more fun. Of course, this doesn't limit to schools. We actually, there are some hobbies or companies to actually purchase some of the kids from us to actually see whether they could integrate it with their current company solutions. Yeah. So, these are some of the things. How can you involve? Because everything is open source, sometimes things might get a little bit slower or you have buggy things. So, yeah. There's lack of documentation now of documentation meaning like experiments on how to use the boards. Of course, we are working to that and we will be very happy if the users who actually have the PSLAT boards could actually contribute what they do with the board so we could actually share the community as well. Yeah. We actually have an acrylic casing. We cut an acrylic casing with a laser cutter if you managed to catch it just now. So, we actually did the design with Inkscape as well. It's also on the Github Ripple. I mean, yeah. If you want, if you managed to purchase a PSLAT if you want acrylic case, you could actually just fork and find a laser cutter to cut it out on an acrylic. Yeah. So, these are coming some of the places we sell. Yeah, very straightforward. Okay. So, this is our summit next year, Four Seasons Summit. We have this every year actually at Singapore. There's actually one the following week in Vietnam actually. It's a two-day one but I think that's a much smaller scale. This is a bigger one. So, I think that's it for PSLAT. Oh, we can be found on the Snap Store on Ubuntu. Google Play and Android as well. Yeah. So, yep. Yes. Yes. Okay. So, Electronab is a cross-platform. So, you could actually export. Electron.js, right, is actually you program it in JavaScript but you actually could export it to Windows and Mac as well. But the base currently we are working on heavily is actually mainly on Linux because with the Python library. Yes, correct. Yes, default it should be able it will be able to run with Linux is not very stable and things like that when we export over. Two Mac. Yes, it was two. I think I should previously two. So, two for four channels. Yes, I mean of course our point is actually keep this price point low and this is about actually I think 45 to 50 USD. Currently of course there's competitors in the market. There's everything there's competitors. Our main point is to actually keep it price point low so that it's affordable. Of course, there's higher specs much more expensive or FVGA things like that. There are better specs but yeah it differs from person to person what they want to actually achieve. Yes. Of course subsequent will be actually I think planning to do the next production version of PSLab. I think actually has more it goes to as a more of IoT devices IoT devices to actually put around maybe without the phone just maybe a battery pack or something to to store data maybe one hour later one day later just come back and just collect the data. Micro SD card. Yes, correct. To store the data. Of course we are looking at the cost and of course the software side as well. Any other questions? I think if there's no questions if you want to look at the board. No, actually this is our own board so we have our own firmware and things like that. So it doesn't work with Arduino but we have the Python library open. I'm not very sure but I think it might be possible to do that with the Python library. Yes. Of course like I said we are working with schools. I wouldn't consider this some people say this is quite high specs for considering it's 45 USD around there. Of course to some people they are professionals they want something more powerful. Of course that's right. It's more suited for schools or company usage small usage, IoT usage data collection. And I think it works with Arduino sensors which is I2C. Of course we have pins for digital sensors as well. But that one is a little bit more time because there's a lot of sensors in the market and we actually have to make it the digital sensor works with the firmware as well. Yes. There are some digital sensors that should already work is in the settings of the app. You could actually choose the external sensors of which sensor to use from because for example we actually have like say we have instrument called lux meter that actually taps on the phone's light sensor to ensure the lux data. But of course we give an option of them to actually connect an external lux sensor light sensor to read the data from it and record. Yes. Anymore? If you want to look at the board, we are at the four-seger boot outside. So it's already done? I'm done. Thanks. Okay thank you Mr
