 Hello! I want to thank you all for just all the likes and nice comments that were put out on my daughter's video that I put out a week or so ago. It is probably the fastest growing video on my channel. When I created it, I was a little concerned that people wouldn't like it. And I also, when I was editing it, I wanted to edit it shorter so it would be a little more, you know, less drawn out. But I was worried that if I edited it too much, people wouldn't really think that she was doing what she was doing. So it was longer than I had intended. But besides, she got two thumbs-downs, which you're always going to get two thumbs-down. She got so many likes, so many views, and so many nice comments. So I just want to thank you all. And Ember will definitely occasionally be joining me in other videos in the future. She had a great time with that video and she's excited that you guys liked it. So thank you again for that. I do want to address, so out of all that, there were two negative comments. One was just some guy who wrote So Sad, which I don't understand that comment. And the other one was a valid concern. I think I basically said, you know, I don't want to be, I'll say a prick. That's not what he said, but I think this is fake. And at first I'm thinking, okay, he doesn't think my daughter can really do these things at five, which I 100% promise you she can. She does it daily. She loves using her computer. But his concern was valid. What he was concerned was that he thought it was impossible to turn the light on and off from her laptop, which was probably more of a valid concern 10 years ago. I think most people realize there's a lot of home automation devices in the world now. And the way we're doing this, there's two different ways I've shown in videos, and I'll leave links to those at the end of this video probably, and I get replied in the comment. But let me just quickly go over and explain what's going on when she's running her light command. So right here is a little room box next to some of Ember's artwork, because she made herself a little connect-the-dots thing. It's a wooden box that I made, and I have a video on my second channel where I made this room box. And I put one of these in there. This is an ESPA266 chip, which is like an Arduino with a wireless chip in it. It could be an access point or client. It could run as a web client or a web server. The one in here is running as a web server and it's connected to my local Wi-Fi, and it is connected to one of these things. So these are a transmitter and receiver running at 433 MHz, and literally you can get a transmitter and receiver for about $2, so a dollar a piece, and these are about $3. So we got about $4 worth of hardware in here. And so I can connect to the ESPA266 as if it was a web server, meaning that I can use a web browser or a program like WGet or Curl. And I send a signal to it with either a post or a get request. I can't remember. I think it's a get request with a certain numeric code in it. And it sends that code to this, which sends out a signal to one of these, which is a zap outlet, which are about $5 a piece, that come with a remote like this. So basically, when I press a button on this remote, it's sending a numeric value through the airwaves, and all these devices read it, and if it's the right code for this device, it will turn on. And if I send a different numeric value, because there's on and off buttons, I can turn it off, and that's all my daughter is doing to control this. I've also done videos on smart plugs that are actually running Linux, like I think it was called the Cancun plug, which is running Linux, which you were able to hack and get a root access on. And again, same thing, I run the WGet request directly to the outlet. So there's a little intermediate here, but this is a lot cheaper, because those, when I was buying them, it's been a while, were about $20 a pop, where these are $5 a pop. You can get five of them for $25 and two remotes, actually a little less than $5. And we have this extra piece of hardware in the mill, but it actually makes easier, because those Cancun plugs, I got set up on my Wi-Fi and all this stuff, where one of these I plug in, and I can record the signal being sent out by the remote, and then replay it through my device here. But these also have a button on the side, too, so they can go and learn mode. So I just make up a random numeric number that I send to this device. I hold down this button while it's plugged into the wall for a couple of seconds, and then send the signal there, and it learns what signal this thing's sending out, and now I can turn this outlet on and off through Wi-Fi to this device, and then from that device, add 433 megahertz through the airwaves. So that's how I do it. It's cheap, $5 an outlet. Big drawback to that is that it has to be done through a wall plug, so I can only use lamps. But at the same time, I have these, which I got for Christmas in 2016 and still have not even tried using yet. I got three of these, and again, they're a few dollars a piece, but it's an outlet that you can socket. You screw it into your light bulb fixture, and then you screw your light bulb into here. Also running at 433 megahertz comes with a remote, so there you can control, and they're also programmable, so you can program all three to work at the same signal. So there, now I should be able to turn lights on and off as long as it's a light fixture that this can fit into, which is rather large, but some chandeliers might be able to take it. And the other drawback to this is that you still have the light switch. If someone turns off the light switch, you won't be able to turn this on, which actually, I have something for that. I got these, again, probably about a year ago, a few of them, ordered them off at eBay. So this is one big button, and I got three little push buttons here. Again, running at 433 megahertz. So theoretically, I could hardwire my light switches, and then these stick on the wall and act like light switches, and these were like three dollars a pop. And I knew they were cheap, but they're a lot cheaper quality than I originally thought, and I really don't want these things on my wall. So I don't know. That's one of the reasons I haven't tried using those things yet. But regardless, I could have my light fixtures running the same way the outlets are running, and with a simple WGET or curl command, or just open up a link in the web browser, I can turn lights on and off, or other devices that are plugged into the socket on and off from my shell, from any computer, from my phone. I mean, that's why I do use it for most. I can just go to a link on my phone, and it turns the light on. Go to another link, it turns it off. Actually, I have push buttons that send the HTTP request. But the viewer who posted that comment, I understand your concern that it does seem weird someone turning light on and off from a computer, but it's 2018. I've talked about two options here. Smart plugs that are running Linux. These wireless outlets and sockets that run at 433 megahertz that are really cheap. But there's also things like the Wink Hub, which I don't have one, although a viewer recently told me he was going to send me one, and I never received it, and that was a while ago, and I completely forgot about that till now. I don't know. But there's lots of ways that you can turn lights and other devices on and off from your computer, through your Wi-Fi, or other wireless signals, which you can connect through Wi-Fi or even Bluetooth, which I don't mess with much. So that's it. I understand your concern. But again, 2008, yeah, this would have seemed far-fetched, but not impossible because back in the early 2000s, 2001, I actually worked for a company that installed, I didn't call it back then, but Smart Lighting Systems, the brand name of the devices we put in were Lutron Systems. And back then, we would put them in these million-dollar homes, and there were these big modules, and it was used when you're building a new home, they would run wires to these modules, and each module was over $1,000, our cost, before we marked it up for the clients, and they had to go into panels, and the wires had to be run. So you're looking at, like, at least $1,000 per set of lights in a house. And in most cases, they were just controlled by buttons. So each word there would be a switch. There would actually be an eight-button panel, and you can press the button and it would turn on the set of lights, and my job was to program those. It was more of data input, but I was programming them if-then statements kind of type thing, where if this button pressed, turn on this set of lights, this set of lights, and this set of lights at 50% strength, or you push this button, this set of lights comes on, slowly dims up to 80% over three seconds. That's the type of thing I programmed, and for the most part, it was done by those wall switches, which were directly wired to a panel, usually in the garage or a closet somewhere. And then there were, if you had already had a house built, there were wireless ones, which were really expensive. But those devices also had the ability to hook into your phone lines. Again, this is 2000, 2001. You know, high-speed internet was a thing, but not really around yet, just like home automation. And we could program it so people could dial in with their phone and hit 1 to turn on the lights in the living room. So if you're on your way home, you know, get your lights on before you got there. But there was also an option to dial in through a modem, which we never really set for clients, but we could troubleshoot that way to where we would use it, you know, dial up to dial into their house. We'd dial their number, and then we could turn lights on and off from our laptops. So, you know, not too far from what we're doing here, only through, you know, regular, you know, pop phone lines and extreme cost difference. I mean, really now we have what they had, these multi-million dollars houses had that cost thousands of dollars to turn on one set of lights. We can do for under $10, easy. So, yeah, it's nothing new. It's not that hard to do. Detailed tutorials on my second page. This particular setup, or before that, I did one on my page on this channel here using the Cancun smart plugs. I'll try to put links to both of those at the end of this video. But I just want to clarify, I thank you for watching, and I hope this, you know, puts any doubt to your mind that the video of my daughter working on her computer was 100% real. I thank you for watching, and as always, I hope that you have a great day.
