 So, I've distributed some paper, so I hope that many of you have also paid. If not, we can try to share and distribute some paper. So, let me go back. Okay, so, we have a few sessions. We have a few sessions of hardware, basically, I've been trying to think of a quiz, something to do with everybody just to be really trying to capture all the stuff that you've been learning by some presentation over the last one or two years. Really, the important thing of this is just to try to stay like 10 minutes. I think it's only five questions. And it's just to make people reminded of what we've learned or what we've basically discovered over the last few, many, many sessions. And the idea also is that the price that will be given probably in the next session come from a lot of things that have been actually related, including books, bits and pieces. So, there is no, okay, how do we go to the slide first? So, it's a small quiz, five questions, four possible answers, only one right. So, don't put, basically, all the questions for the answers, something, the right one which we can sort of put in the paper for the whole day. Results in, I guess, the next hardware session. No, there's no winners really just for fun and I will give some hardware and some books, but few books to give away. So, let's start if there is a release. So, the questions are about IOT, FPGA, police, things that should be simple and things that should be a bit more hard if you've been listening to some previous sessions of hardware. So, I'm going to start to go slowly, there's not much time, and go through all the different questions. First question. So, this question is about the basics of electronics. We know building and designing circuits. So, this is the essential element of electronics. So, as you know, they are the brands of colors, and the three brands, the first and the second and third digit, then there's even the player, and the last one is the tolerance. So, everybody knows that the tolerance of 5% is the color gold, 10% is silver, but what is the color of 1%? So, either brown, red or orange yellow, I tried to simplify the solution, and on your paper you should just put the name of the color. I guess I would think that half of you have been using electric resistors. Of course, it's as simple as in Italy. All the other ones are orange. No access to the internet. Are you ready for the second question? Okay, so, as you already know, my interest is maybe in FPGA. So, the tool of my design is called Vimadu, and we know that FPGA is actually quite expensive. So, the developers are getting cheaper and cheaper, but in terms of software development, I often repeat this in my talks. Vimadu design suite is at $100 USD, at 100 Euro, 100 Malaysian credit, or is it free? Or at least you can do that later. This is one of the main points for me to motivate people to start to do some FPGA, and I'm going to go to your group. Question number three. So, transistors. In my old days, I used to use the TO-3 to do some audio amplifiers, and also policy files to have some of these. So, we all used to the TO-92. That's the only transistor that we used to drive by EDEs at the end. The TO-20 to the TO-120, this is used in a particular amp, usually a voltage regulator. The TO-3 is less usual to drive some proper amp into some stickers. But one is the other one, which is usually transistors using HIF, HF, or that sort of electronics. So, it's either TO-7, TO-13, TO-18, or TO-51. I have also learned today. Too difficult, too easy. And then you say to some people we had the paoshi on some regulators and the amount of heat they can dissipate, etc. So, the package of components is usually very important. Okay? Question number four. An FPGA. They will be out here, don't worry. So, Xanis has in the FPGA hardware some DSD sites. Another part of the range of the latest FPGA from Xanis has the DSP48E. So, is it E1? E2? E5 or E extended? It's come from my recent purchase of a newer FPGA which I have one of these. Of course, I found a little smiley that not has to answer actually. But this one, specific FPGA. Probably too difficult. I think this one is basically working. Yeah. Okay, question number five. So, sometimes when you use an electric, you have some electrics. And really, in my years of electrics, I always tend to not use the electors. These days, we use that for the power of some regulators, etc. An elector is using a standard unit of Johnny, Harry, Terry or Henry. I was looking for some pictures. I find that there are too many people who have those names. Which one? Oh, okay. Yeah, it kind of gives away because he is the only one. If I put Henry as a footballer, and I had two footballers, then I thought that you know, the crime would go like, ah, I wanna get the other thing. I get this one. Actually, Harry, I could use a printer. Okay, question six. The different behavior in frequency domain, the little compromising using a capacitor and a resistor, is known to be. So we have different paths. So one is a low pass at E, the other one is a one pass BP, the other one is a high pass HP, and you have an EP, because this is Singapore. So you have to find out which nitrate is actually the one now. You have PR now, so let's see if we have to do something different. We all must have used a circuit at least to, to help in our design and IoT as well. Question seven. FPGA again. So over the years, Xionist progressive introduced, as his family of FPGA, the Spartan, the Vitex, the Kipex, the Artyx, and now the Ultrascast. So which one of these, Spartan VII, Vitex VII, Intex VII or Artyx VII, is the most recent? And this one actually has a very good thing to, to IoT, because it's actually a family of FPGA, which is supposed to be low power, not so much processing but more low power, and Vitex VII is so, they are sort of targeting the IoT market to business. They all look the same. Question number eight. Electrons. So when a capacitor, when a capacitor is an arranged in parallel, the new random capacitance is the sum of those. But when they are arranged in series, what is the equivalent capacitance? So these should be the basic rules for you when you design your thing. So the first one is, if you have the first one, twice the second one, plus three times the third one, or you multiply all the values, or the inverse of the equivalent is the sum of the inverse of all of them, or even more clever, you use the median, median value of all of them. That would be the first. So I think these are the basics of electronics. Or hack away. These would be some sort of interview question for how we get out. What is this usually? PSI's and all this simulation software. So you don't really need to know. You just provide you with a little simulation. Okay? Question number nine. How well? If one makes a trigger between flexibility, programming, attraction, performance, area and power, efficiency and cost, let's say, which are the following of the coolest technology around? You use a CPU, a GPU, an FPGA, or an asset. So I think this one, it's a trend. So cool means, I mean, cool means cool. That's the next one for this one. I like the black arrow or the asset developed with my own convenience. It's quite cool. I mean, when you design your IoT, you can take some trade-off between power, processing, speed, et cetera, et cetera. Okay, question number ten, IoT. IoT is a very hard topic. So to give an idea of scale, it was reported that in 2014, about 18.6 billion macro-colons were sold, about 92 or something like that. And in 2016, 10.3 billion views of every 5G time were sold. So how many billions of IoT devices you take will be by 2030? So let's say 50 billion, that's sort of prediction. No one knows. So actually no one knows that your music group, I don't know, that's the only picture I can prove. It's actually good for what you made a picture. A trillion. So those numbers become quite good. So I was looking at the number of zeros that are about 1.3 billion and 2.5 billion. And then 2.5 billion was like those ones. I like 2.5 billion. So hopefully in 2013, we can have our Hackerware machine in, you know, 1,600 million. And we can look at a number of IoT devices for sure we'll give you 2.5 billion. Question number 11. Looking around in the IoT sphere and looking at the interfaces because that's really quite cool. So currently most of us are using OneWire, RS232, as you can see, but recently we'll be a alliance to introduce a new paper, whatever, on some interface. So is it one? RS696. Basically you're dripping your sealant on. Is it an SPI extended with some very similar timing of the SPI from before? Is it a new USB 4, which has 8 ports? Or is it an ITC which will come probably end of the year with some prototype or some new chips? So we have to look for this one. This one may or may not be the future, but I could better admit that there will be a lot of interest on it. Including USB 4 because after USB 2, USB 3, USB 3C or some sort of new there will be USB 4.2. The point is that SPI is a kind of an interface we can use in a quite a lot of the time SPI so probably we'll have some issues also. Last question. So I went to some IoT talk with the IoT I remember the name it's in every Thursday of the month one Thursday evening So there was a talk about 6 ports no advertisement I'm French but and they actually had the company called Unibus in Singapore and they released this little board which has a 6 ports chip and when you buy it it's actually included in the subscription the thing I wanted to really confirm So another thing for the price and also whether people would be interested to have a workshop with it if you organize a workshop and you have 10, 25, 50 people that you can get some discounts so the corona will provide a discount I mean I will tell you what is a discount So the question is how much will it cost for a single chip not much on it the chip until I think a couple of products So is it $20? There has been a piece where we organized IoT in Singapore and gave it for free Is that a real I don't know if it's a new one Is it a new one? Is it $65? Or is it just $100? So this is the price I guess maybe later on you could be interested in actually asking for what do they expect to be affordable and put the 6 ports IoT together Maybe you can give our input into this aspect Okay so I think we saw the last one So if you finish to just write your name and put the right answers on the piece of paper So I will look through them and then in the next session I will probably provide 30 or maybe 30 gifts I will see how many stuff I can find in my case There will be new sorts from very heavy books to small electric stuff that hopefully you can find useful yourself Thank you very much
