 Selamat tinggal, saya Mark Chu, currently studying at SGTD. So, this is my first time at HECOED. So, what happened is that like 2 months ago I actually went to Star Weekend. So, 2 months ago I went to Star Weekend. I joined a team there and then we managed to win the most creative prize. So, what my team leader Christina, she's a mother of 2 children, then she's like super paranoid about getting her child lost because of some events that happened in her past. So, what she thought up was to put a GPS tracker or GPS tracker in children's shoes so that they would never get lost. So, in other cases that we were thinking of was also dementia patients or other vulnerable people like there's this or patients in hospices. So, in case they get lost out in Singapore then the police are like friendly searching for them. So, maybe because why we wanted to put the GPS tracker in a shoe is because there's a lot of GPS trackers out there like wristbands you put in the bag. So, what she thought was that patients with dementia and children they can just take off the wristbands they can just throw away the bag but at least for a shoe you know that they'll most likely put them on. If they don't put them on, if they're out walking in the streets barefoot someone will call the police and get them back. So, that's why we wanted to put them in the shoe. So, this prototype we'll hear is we are using like particle electron with a GPS asset tracker shoe. So, we also have now operation which is the close range so that the GPS doesn't always have to be on and it's very power consuming. Bluetooth is when you're in around 50m range. So, it tells the parent where how close the child is in proximity to you. So, it can tell you like the child is near, far and once it exits that threshold then it can notify the parent that the child is too far away, oh no. Okay, then it can send you the GPS notification. So, we're using electron particle with asset tracker shoe. Our Bluetooth BLE module is HM10 so it sends out iBeacon signal which a phone can detect. And then we're using lipo battery and acerameter so that to become more power saving really activated when the shoe is in movement. So, actually now we are trying to turn this into a business. We are currently looking for ARM programmers to take it to the proof of concept level. So, if you are interested, you can contact me or contact us. Very interested to have people joining our team. Okay, thank you very much. Next, your name. How lucky are people to remember to recharge their shoes? So, this one can be brought with GPS and loan. I think it can last for around 2 weeks and you ensure that you use all the power saving methods as much as you can. But what we actually propose at start weekend was we want to put in POZ electric charging so that when you step on it, it will charge. But we know that POZ, hello, that's Christina, my team leader. So, we actually want to use POZ electric charging so that whenever the child steps on it or the adult steps on it then it will constantly recharge. Of course, we know that POZ electric charging most likely won't provide as much power as we need. Ya. Or is it a magnitude more efficient of budget like SIGFOX or LROM? SIGFOX LROM. We are thinking of using MBIOT and LTE-M networks. You're still using SIGFOX. SIGFOX. SIGFOX. Alright. I guess MBIOT is probably on the same kind of deal. Is it? You're negotiating. Well, that's the Toko problem. Toko's got the sales deployed. But the idea with SIGFOX. Certainly SIGFOX. Certainly the idea with SIGFOX is not the receipt. Because SIGFOX already depends upon receiving at multiple stations. Then they simply exploit time of arrival information to triangulate. So you don't need location capability on the device. What you need is that the SIGFOX chip is transmitting every 10 minutes. And this is a really cheap chip. So really like a watch battery will run the thing for 5-10 years. Which is... I was sorry. I ran tendensial comment. But there's a conference in Singapore in two weeks or something on low-power radio frequency stuff. A bunch of SIGFOX people coming down and a bunch of LORA people coming down. I got to know because Bausheri treated someone and I got into a tweet stream about 20 people coming down and he was telling them to come here tonight. But they're all like, oh, we're coming in two weeks. So we're not going to be here. We're specifically going to be a hackware, casual, show-and-tell whatever. No guarantees. I will put it up on the regular Facebook and meet-up. Let's do that one. So what do we call it? So if the guys reply to me and they're up for it because a couple of them want to come and hang out at Hackerspace. So I was like, well, if you guys hang out, let me know. I don't know about what conference it is, but I'm seven seven. I'm sorry, I wish I could respond to this coming to Singapore. It's hackware plus plus. Hackware plus plus. Anyway, I'll put up the long range. Okay, that sounds good. Hackware low-power. It's called SIGFOX Connect, apparently. Hackware Connect. Good job. SIGFOX Connect 20-21 November, Singapore. Okay. We just hijacked that name. Hackware Connect. That's a fancy corporate conference but if some of the people want to come down and hang out here to the room. That's what it's all about. After. Yes, sorry. It means you have access to it. I'm not sure. If it works out, because the guys haven't replied to me, I gotta put them again. Okay. Thank you.
