 Jadi saya bekerja di Komitee Marriage Network yang juga membuat spesial di Unitover College. Okey, so basically we today, okay, this is something that I put together because I was rather stressed out from work. Okay, sorry, can I just turn this off somehow? Sorry, I don't know what is making it. Okay, so during, I think around Christmas or something like that, and then I decided to go down to Giant and pick up an oven and then build something. Okay, making things distress me. Okay, so basically this is a super, I won't say super lah, but it's a rather low cost oven. Okay, this is my standard slide. Okay, so I've been doing hobby electronic things that I was like 10 years old. So those were the days where you tried to solder everything, date back everything and stuff like that. So after that, when it comes to fabrication, we always want to better, more professional looking circuits and stuff like that. I'm sure you'll be very familiar with that. So, during 10, breadboarding wasn't the most popular solution. Okay, but I think nowadays it's very easy here and cheap and simple, easy to use, easy to modify, but it's not personal. Okay, if I can put this here, I'll put it on breadboard. Okay, because I'll put it on breadboard. Okay, so it will take up a lot of space and breadboard size is actually pretty big compared to a PCB board. Okay, and basically only through whole parts unless you solder your SMB parts into pin and plug it in. Okay, so that's wire wrapping. Okay, so it's a slightly better solution. You can get very neat boards and stuff like that, but then somehow wire wrapping... So, as you can see, it's very easy to modify and then put it on simple, but how do you get it? You want to try to put it on the pin. Okay, so it's easy to modify and then put it on the pin. Okay, so I can put it on the board and then put it on the part. So, as you can see, I think it's very possible as a reader on a PCB and stuff like that. Okay, so it's easy to... because I think there is authority in the making space. So, you want to expect confusing as soon as it's auto. So, you can get simple flip-flop circuit so that you can fix some lights and then do a lot of things. Okay, and actually if you put up the lights and start right, so most of the everything is simple and then put it on the pin. Okay, so, as you can see, so, and next, as you can see, it's easy to modify and then put it on the pin. So, you can see it's very easy to modify but as you can see, so, you can get from 24 in to 90 okay, but as you can see, it stays simple and it remains the transport method but as you can see, it's very comfortable and a perfect solution but as you can see, it's very simple but as you can see, I'll let you guys go through. Okay, so, As you can see, It's easy to modify and start and then put up the top and put up the top and put up the pin and then put up the speed. I can't. I can't. I can't. I can't. I can't. I can't. So, how this is about the cost of the hotel, I think, under $1,000, which is a new one, which is, I think, about $3,000, okay? The rest, I'm going to get it in Singapore, and I'm going to leave it at that. So, as I mentioned, I chose one of the rooms in the hotel, but I think I'm just an assistant of the hotel. Okay, so, it's a little bit of artisticity, because it's very convenient, easy to, very, very important for the conversation of this sort of thing. It's not too easy to discuss how to correct the picture, okay? So, it changes, it is not as easy as it was. Okay, so, this is the basics, okay, lah. Okay, so, it's actually high-target based, okay? I reckon it's המ� physiology but are unique whole advices. Can help you to protect yourself further. Start all the way down to heaven. Don't waste all day thinkin' the moment. So, I'll just remember that Jeunchae Lakiput. Okay? So the idea for this fit's is that it might be easier forandioveruniversi or something like that. And it definitely is need for saigkeit lak. Okay? So rapport that I can use. I'm actually strut up with something called New Portable app, So, this is the second customer I expressed. Okay, it's ready to go. So, this is the final after-value. It's ready to go. So, this is the final after-value. So, this is the final after-value. Okay, so, the only thing I actually mod about this oven, okay, it's my oven, okay, is that I just removed the, or I shot the timer because the timer, if you need to turn on the timer just to reflow, it drives me crazy because I didn't go 50, 50, 50, 50. I'm sitting right next to it, so I removed the timer. This is what the finished product actually looks like. Okay, the reflow product, you all might want to pass around. It's a break-off board for... Microbead. Microbead, yes. You put the microbead in the oven too. Okay, the board that came from JLCPCB looks like that. Okay, it's a board for IoT game that we run. Okay, so, we are going to reflow a few pins on this board so anybody interested can come up and take a look. Okay, so basically, when you order your PCB, you can order it together with a stencil. Okay, this is a stainless steel stencil with small little holes, laser etched into it. So you use this stencil. Okay, so basically you take the stencil. Okay, I stick it on the board because it's actually quite flusy. So what I'll do is I will place my other PCB board to raise it up so that it's flat. Okay, the only thing is that I just happened a few days before I actually threw away all my old batch of PCB board. Okay, so I use back this same board. Okay, so what I do is I'll put the board. I'll put the board. Yeah, I'll put the board here. Okay, and then after that, I'll put the stencil over it. And then I apply the solder paste on. So the solder paste looks like that as I shown earlier. Okay, something to apply the solder paste I use an acrylic paint. I don't know what it is. And something to wipe it. Very useful. Okay, so maybe we can just solder. Okay, the most difficult part to solder on that particular board is actually the USB connector. Okay, because me being cheapo I ordered the cheapest micro-USB adapter. Okay, and the pin is recessed into sort of almost under the plug itself. So for, you need a very small soldering iron to drag solder the thing on. So at most of the time, I will try to treat it as before and get it. So that takes a lot of time. But this one, I don't even care. I just dump it in and bake it. Okay, so let me find the connector. Okay, we can put on a connector. Two questions. What is the render of the sensor? 500. Can you render drilling? No, I didn't do anything. So the whole idea is low cost. I want something that I don't have to... Occasionally, I can still toast my bread or something like that. No, joking. Okay, I'm going to do it eventually. Actually, I wanted to do it. I bought RTV silicone and that. But then Donna say, do I want to do this? Okay, if I want to do this, I want to do it raw. So that anybody can just buy an oven and then just plug it in and get it to work. Do you still make food to eat raw? Originally, everybody say, don't mix your reflow oven with food and stuff like that. I actually don't believe any shit of that. I thought it's okay because I do a lot of sorry and I don't find that it's very smelly. But this stinks. We'll get it. Sorry? Ya, you can use a low temp unleaded soda if you want. Ya. I'll let my focus extra. What I did is... Okay, so we have... Temperature control? Is that your thing to turn it off and want to resize something? Ya. Okay, I do... I do woodworking so I have a lot of wood at home so I'll just take one piece and mount all my component on it. Ya, it has a breadboard on it. I don't drill into the wood. Your windows, you need to... Okay, what happened is that... I mount everything on the board. So this is the main power. Actually, I don't need a single gang. And then most of the time, I cut this smaller but then I only can find a double gang. Okay, so anyway, the computer crash. Ya. Okay, so anyway, the computer crash. So we plug it in. Okay, there's an SSR on it. Okay, we plug this onto it. Okay, let's see whether I can get this up or not. Okay. Okay, the sensor is... It's just kept on tape onto the... onto the tray. Okay, so what you do is... I didn't drill a hole so I... I just shove it into the middle or upper slot. Okay, and then just close the... Okay. Just close the door like that. Okay. It's not optimal. Okay, because you get heat leak and stuff like that. But because the oven is so small. So the temperature control is very easy to control the temperature. Okay, maybe we will just do it without the... So basically, the computer is just to power the WiMOS. Okay, the WiMOS run a small web server to show the temperature and stuff like that because I'm trying to tune the PID. So if I don't know what's the temperature and all that, I don't have an infrared temperature because I just woke up one morning and decided to do this. Ya. So what we do... Okay, so with... Okay, me being almost blind. Okay, I need something to look at it. This one? Ya, unique. The lens will... will get electrocuted some way. It's just... I have a lot of this bag. Just bag one. Okay, so we take some paste. Okay, we put it on the USB port. So this is how the paste look like. Okay. Okay, I got this for $15 locally. So it's a ripoff lah. But because I was desperate and I need it. Okay, I have 10 bottles coming from Aliexpress. Okay, so you apply the solder paste. Okay, so normally I will put one whole strip of solder paste and I will use this nice little card to squeeze it over lah. Okay, but then now... because we are just doing a quick demo. Okay, so when it's done, okay, you have your... No, sorry. So if you didn't get it right, just wipe it off. Sorry. Ya, but... How long will you take to initially line up your solder paste? Very fast lah. I'm not that blind but... Okay. I hope I have a microphone. Okay, so... Sorry lah, somehow when I do demos, it was... Okay, this paste that I got, it's a bit dry. Ambrose. Okay. Okay, where's my... Sorry, I cannot find my... Okay. Okay, so this is like... this is like maybe my sensing. Okay, it can go up to a few dollars lah. So I chose the cheapest one. Okay, so it's very small. Okay, so... I'll use a pincer. Okay, and then you press down on it. Okay, it's a bit sticky so you'll get stuck on it. Okay, so now we have USB plug on some solder paste. We'll put it inside here. Okay, it's like cooking show lah. Okay, give me a minute lah. I'll answer that in a while. We'll turn it on. Let's see whether I can get this up or not. Ya. Sorry, I cannot remember. He takes me out? Okay, so... it will show the temperature. Okay, so once we keep the switch on, kemudian kita terus bergerak, kita baru bergerak, jadi kita mulakan dengan, sebenarnya saya sedang bergerak jadi kita akan mulakan dengan menggunakan kawasan, okey, ke sekitar 180°, kemudian selepas itu kita akan mulakan ke sekitar 190° atau 120°, kemudian selepas itu kita akan bergerak ke sekitar 215°, jadi ini akan bergerak pada 215° jadi jika anda dapat melihat, harganya sebenarnya di atas sekarang jadi untuk bergerak dengan kawasan, ini adalah kawasan adek, jadi ia hanya bergerak dengan kawasan adek okey, jadi 120°, kemudian ia bergerak ke sekitar 180°, kemudian kita mulakan dengan bergerak ke 215° ke sekitar 215°, saya sebenarnya beli satu dengan kawasan kawasan, saya sangka saya dapat melihat, tapi sebenarnya tidak sangat sukar untuk melihat okey, jadi apabila anda bergerak, ia akan bergerak ke sekitar 200° atau 215° saya juga meletakkan kawasan pada setiap kawasan yang berbeza jadi di sini ada seseorang yang harus bergerak ke sekitar 100° jadi keadaan ini sebenarnya bergerak ke kawasan jika anda bergerak ke sekitar 100°, anda tidak akan bergerak ke sekitar 100° okey, jadi saya bergerak ke sekitar 304° hanya sebuah kawasan yang bergerak ke sekitar 205° dan sebuah kawasan yang bergerak ke sekitar 100° saya tahu, element 14, ini adalah kawasan saya dari LCS semua kawasan ini dari LCS bagaimana kawasan yang bergerak ke sekitar 100°? okey, 3 nama, DHL bergerak ke sekitar 100°? iya, SL2 bergerak kita dapat mengalami kawasan okey, jadi apabila ia bergerak, okey kerana tiada kawasan yang bergerak atau apa-apa jadi anda perlu membuka kawasan dan apabila ia bergerak, pakai sesuatu untuk kawasan jadi ia adalah sebuah latihan yang baik jadi anda kawasan sehingga kawasan bergerak ke sekitar 50-60° dan ia sebenarnya selamat untuk mengeluarkan bagaimana lebih banyak masa sebelum anda tidak cukup untuk minum kawasan yang bergerak? saya tidak tahu, bagaimana saya memasak kawasan yang bergerak ke sekitar 30°? iya, jadi saya perlukan kawasan yang dapat mengambil kawasan dan memasak kawasan di dalam kawasan kecil seperti itu saya tidak fikir saya ingin melakukan itu anda hanya perlu memasak kawasan? anda hanya perlu memasak kawasan? saya tidak mengubah kawasan yang bergerak jadi apa yang bergerak? Untuk memasukkan SSR ke dalam bahagian, kerana sekarang, sebuah wajah wajah telah diletakkan. Untuk mendapat keputusan, anda dapat meletakkan. Jadi, itu satu perkara. Yang kedua adalah, saya mahu 2 SSR. Jadi, saya boleh menghidupi top dan bawah. Mungkin melakukan sesuatu fensi. Mungkin menghidupi top. Jadi, saya akan menghidupi ini. Jadi, setelah itu, perkara yang terakhir adalah servo untuk menghidupi top. Tidak ada apa-apa. Tidak ada apa-apa. Saya akan menghidupi semuanya di sini. Jadi, semuanya di dalam bahagian. Jadi, sebenarnya, sudah selesai. Sebenarnya, ia sangat baik untuk menghidupi top. Mungkin saya akan menghidupi satu pindah. Jadi, saya akan mencuba, sebenarnya, untuk mengambil beberapa pindah. Pindah liquid untuk menghidupi. Sebab saya menurut saya bahawa ini sangat baik untuk menghidupi top. Jadi, pindah saluran sangat lembut. Jadi, apabila ia lembut, ia tidak berada di dalam bahagian. Mereka akan keluar bersama dengan pindah. Sebab ia menghidupi. Boleh saya lihat? Jadi, itu menghidupi pindah saya. Ada sebuah pertanyaan lain? Jika anda menggunakan pindah yang sangat baik, ia tidak akan tinggalkan pindah. Pindah ini, anda akan dapat beberapa pindah pindah yang di dalam bahagian. Jadi, anda hanya menghidupi dengan IPA. Saya lebih suka Sito. Jadi, anda hanya menghidupi dengan beberapa pindah. Anda akan okey. Semuanya sangat baik. Bagaimana bahagian saya? Ya. Jadi, semuanya, seluruh bahagian yang diambil di satu bahagian. Ya. Ya. Okey, jadi, apa yang saya belajar daripada proses ini? Okey, ada beberapa perkara yang anda perlu tahu. Okey, bahagian yang diambil, walaupun ia boleh diperkenalkan, ia juga harus menjadi sebuah kelas yang diambil dan kelas untuk hidup. Walaupun anda akan mahu membuatnya menjadi sebaik-baik saja sebaik-baik saja, anda masih mahu. Kerana tidak banyak bahagian, bahagian boleh mengambilnya. Ia adalah komponen. Jadi, komponen akan dapatkan perang. Dan betul. Jika anda akan memilikinya, terlalu cepat atau terlalu mudah. Jadi, ini adalah perkara yang saya belum menemakannya. Jadi, saya belum perlu menemakannya. Walaupun, ada beberapa perkara yang menghidupkan. Seperti beberapa perkara kecil anda, SMP, ABR, jika anda memperkenalkan, anda akan memperkenalkan dalam perang sebegini, kerana ia memperkenalkan sebuah kelas. Dan kemudian, kelas akan membentuk dan memperkenalkan kelas dan sebagainya. Jadi, ia adalah masalah yang anda lakukan apabila kelas itu memperkenalkan lebih banyak kelas daripada tepung. Kerana ia terlambat. Jadi, ia memperkenalkan lebih banyak kelas daripada tepung. Ya. Jadi, itu adalah proses belajar saya. Saya bukan expert dalam ini. Saya hanya mencuba. Saya tidak memperkenalkan beberapa kelas daripada tepung. Di internet, ada banyak orang yang menggunakan sebuah kelas daripada tepung. Dan mereka selalu memperkenalkan sebuah kelas daripada tepung kerana ia sangat susah mengawal tepung pada volume besar. Ini hanya 8 litre. Saya dapatkan yang paling kecil kerana saya juga memperkenalkan tepung. Okey. Teruskan kelas daripada tepung. Ya. Jadi, saya perlu memperkenalkan PID. Jadi, ia memperkenalkan sekitar 200. Biasanya ia memperkenalkan sekitar 2, 1, 7. 2, 1, 5, 2, 1, 7. Jika anda memperkenalkan tepung, apabila ia memperkenalkan kelas daripada tepung. Ini saya memperkenalkan sebuah kelas daripada tepung. Jadi, ia memperkenalkan kelas daripada tepung. Saya memperkenalkan PID untuk memperkenalkan kelas daripada tepung.
