字幕表 動画を再生する 英語字幕をプリント Hey guys, salut, it's Alex. Welcome back to the channel. If you are new, spoiler alert, I am a bit obsessed with sharpening kitchen knives those days. Chef knives are at the core of a cook's work and too often neglected by cooks and chefs. So in the past few episodes we cover the basics of sharpening, like how to use a whetstone properly, how to get the wire edge, how to polish it up. ♫♫♫ That's check. Also, we are... m-m-merde... Also we cover the challenge of the sharpening angle, you know, selecting the right angle for the right knife and the right usage. But! That is all rubbish if you can't maintain an angle steady during the whole sharpening process. Even slight variations in the... sharpening angle will have dramatic effects. It could, basically, ruin the edge of your beloved, very expensive Damascus blade. Yeah, but I'm trying to build a drama here. Well, of course you don't want that. I don't want that. Nobody wants that. The angle has to be consistent, and I think I know how to achieve this. But first I need some help. A few weeks ago, I reached out to my friend Becky, who lives in New York, and, most importantly, is an expert in DIY electronics I told her that I wanted to build a device, a wireless device that would snap onto my blade and that would tell me, you know, as I am sharpening If I'm doing it right, or if I'm doing it wrong. Skype. ♫♫♫ "Hey Becky, how are you?" "I'm good. How are you?" "Good, so good that you accepted to be part of this project! It's a very fun one. Becky: I think so too. I love a good reason to use electronics in our everyday lives. We did, um... discussed this over email already, so you've got a clear view on exactly what I want to achieve with this. Becky: Yes, I have- happen to have one of these, like, all-in-one, it's just like an Arduino with a bunch of sensors and stuff already on it So I didn't have to solder anything together, so this was, like, the very rough prototype I had sent you over email, like, "Hey, proof of concept. This idea is possible. And, like, here's sort of a rough mock-up." All right, I'm loving what I see. I'm loving what I see right now! It's so good! It's so good to connect the world like this! Becky: With this solution would do the same thing as your cardboard template Right, okay? You like the starting and stopping angle But if you want to go further (Alex: Yes, yes.) and get exactly what you are talking about, there is another sensor that is taking all of the sensor data and doing some complicated math to be able to spit out an actual orientation in 3d space. Even considering the acceleration, I mean, the movement? Yes. Oh, wow! Oh, wow! Accommodating for the movement and everything. I'm going to buy anything that I need to do to build this stuff, so yeah. Yeah, sounds great! I'll see you soon, And until next time! Until next time! Merci beaucoup, Becky! See you! Ciao! Yeah, so following the chat, we exchanged a lot. She sent me a list of all the components I would need to make my own, so I suggest we start immediately. I think the board is ready the code is being you know transferred to the board My soldering game is nothing to be proud of I mean I knew it, but I was hoping that nobody will notice Not like "Ta dah! It was that simple", more like "Ta dah, thank god it's over", but anyway. This is the smart little helper. I've been just dreaming about a Bluetooth device That snaps onto my blade and give me information As I'm sharpening so if you want to actually make this stuff as well you might need just a bit more than a time lapse In that case just go out on Becky's channel and watch the whole Assembly process or useful links in the description box and down below But for now, I think we deserve a bit of a chef's knife sharpening. I mean electronic is fun So this is my first attempt So this way I can have the data as I am sharpening I'm gonna set up another camera so that you guys can have a look at my screen and the datas too and so judge my sharpening game First let's check the zero which is goes up to 2.4. But that's not a problem. My aim is 17 16 17 20 21 20 19 12 It is very bad indeed, but at the same time is great because there is room for improvement. Let's start this second attempt It so I might need to find another way to just you know position myself something probably lower Without the shoulders moving, but just the arm. It sounds obvious But the slower you go the slower you move and the easier it is to maintain that you know desired angle fifteen sixteen fourteen Seventeen thirteen eighteen sixteen it's definitely better, okay, so here's what I'm gonna. Do I'm gonna keep those precious advices Close to me. I'm gonna practice a bit more, and then I'll take the leap of faith I'm gonna point the value towards you So you can see them, but I can't obviously I'm gonna get you closer good for the moment. You don't see right let's start (chuckles) I did my best, okay. I'm fully naked I got nothing to hide. You know the answer because you saw the data, but I did not so let's have a look I'm going to really slow 17 15 14 14 14 14 I can see that, man. I can see that 11 you should probably be sure I'm really keen to know what you think of my performance and please guys I'm perfectly aware that you know there are some complex Sharpening system that exists out there like the Lanski system or whatever, but that's not my point I wanted to build a device that would teach me how to sharpen without the device okay, this little device is great But I think it could be improved in many ways a dedicated software on the phone would be better only output But also input the angle you are aiming you have a reset button of course. I'm not saying anything about the Dimensions the stability and also the price point of this little device just because it's a prototype so it's supposed to be bulky Pricy and unstable, but it doesn't mean it has to stop there in fact It's quite the opposite this project is at its tipping point And I believe you guys in the community are the ones who can make this tip? Oh, just tip for that matter How well that is totally up to you guys I believe we could simply make a Kickstarter but I think it's a bit too soon the project needs to be prototype a bit further especially by teaming up with a manufacturer so if you happen to know somebody that knows somebody you know how it works I mean wouldn't you be proud like To have witnessed the birth of a smart little device here on this wacky You Tube channel I would be proud I would I would be beyond proud for both of us well guys That's it But I guess the last thing now is to allow you to subscribe to this channel is allowing us you're not satisfied with things as they are if you always want get better if you want to get Smarter in the kitchen if you think that food is not limited to plate then you my friends are Welcome to this channel take care. Bye. Bye. Salut.
