 No, YouTube is a go. Hey, that took a little while for it to catch up. Is it really? Okay, good. Let me hit Play on there so I can verify that Hi, hi everyone. Oh, yeah, I can't see a preview But I'm gonna just go with that because I have confirmation from people over in discord that we see something Yes, so something terrible happened to my workshop computer and I thought I had fixed it over the weekend But the problem is back so That one is not coming back today, so I have switched to my studio inside and It sounds like we have sound that's good So let's get on with it This is gonna be a low production value show because I literally am just streaming this one camera I have nothing else set up and I don't have any overlays or fancy things So it unfortunately will be a little bit either brief or weird So I'm gonna I prefer weird so let's see if I can on the fly add some add some value to this so I'm gonna go ahead and add a media source and Grab a video that I would have played anyway, so let's see here we go. This is gonna be Lady Aida talking about our product of the week here we go This breakout lets you plug in a cherry MX compatible switch like you see here This is a kale box switch, which is cherry max compatible you plug it in to The breakout board and there's on the bottom you can see on this photo There's a socket and so the switch doesn't get soldered in it actually kind of press fit plugs in There was also on the bottom You see that white square thing that's a neopixel and there's also a diode and the diode is what lets you create key matrices with this thing and the neopixel You see here. There's this kind of like you know There's the two sockets on the left the center is the mounting post on the right There's actually a little slot in the keys and the key Itself is meant for like having an LED Soldered in perhaps, but you can also just have a reverse mount neopixel shine through And then you can kind of backlit the LED with RGB colors. So you have a cutie pie board you know, it's just using Arduino or you can use circuit Python, whatever and These are the keys and I'm just gonna remove them to show you that The key itself plugs into the socket So this is the key and it's got these two Connectors and that those when this key is pressed those connect together and then there's the mounting post where I to keep it mechanically stable so you can Plug it in and then you know, it's pretty stable I would say look you want to have a glued or taped or something to keep it from coming apart because you can pull it off And here's another one. So you have two of them connected together and then on each side you have multiple pinouts There's power and ground here for these are for the neopixel and then this white wire You see, you know goes in here and then chains over to this one. That's the neopixel data line So just like neopixels you chain them together. This has neopixel data going through and then You have two pins for the switch the top and the bottom that and in the cathode of the switch again There's a this diode in the middle so you can make key matrices If you're not doing key matrices, you can just ignore that died there to avoid key ghosting if you're making a complicated matrix But basically you have one pin for every switch and then for this demo when you press the key The LED turns off so, you know, you can just use it as a switch and then control the neopixel separately So they're you know, the neopixel is not connected to the switch at all They're totally separate. You can have the neopixel all the time off all the time. You don't have to power if you don't want to It's just kind of a bonus extra. It shines underneath Here's a demo of the opposite when you press the button the new pixel shines through So it's basically a breadboard friendly way of connecting a mechanical key that is cherry MX compatible to your breadboard There we go. Oh, sorry. That's peaking a little high. No, it looks good So now I could pretend to run back to the workshop to go get one out of the mystery cabinet So why not? Oh bear with me. I'm gonna do just that. Let's Go ahead and add a new media source This is the weird bizarro version of JP's product pick of the week Right Hang on Here we go Yes, that's right. This week's product of the week is the Neo key socketed breakout for mechanical key switches and This is essentially a little PCB that has a neopixel that is underlit for a mechanical key switch as well as a Kale socket so that you can plug in a key switch without having to solder it Which is great if you want to try out different key switches. In fact, I've got one Sitting right here that I have put together. Oh, yeah, focus is gonna be a challenge So here you can see I've got first of all key cap on top of my key switch. I've got a nice clicky key switch and you can see that if I just gently pull those apart the key switch comes out and there's essentially a little spring retention clips that hold those two legs in place as well as a little post to keep things from wiggling around and This is designed to go on to either perma proto boards or breadboards when you're prototyping things so I've gone ahead and soldered in these header pins and You can see here a little demo that I've prepared where I've got a big honkin breadboard and I have a few key switches on there and what I'm gonna do is I'm gonna go ahead and add a very pre-wired For this last one to go in so what I'll do is try to not screw everything up horribly as I plug that in I'm getting an echo. Sorry about that Turn that down. There you go. Sorry about that So if I plug this in I shouldn't have done that while it was running, but I did and I survived so now when I press that Key switch I'm changing this little animated pattern that's running through these And I'm using the LED animation library for circuit Python, which is perfect for this sort of thing because it's non-blocking it allows me to Go ahead and run animations while I'm still watching for key presses. There's a nice little comet chase And go back to that initial sort of pulsing fade loop there And so actually I got a question in the chat, which is what are your favorite key switches? So that's kind of a neat thing that you can use this for if I go ahead and I'll leave these covered But what I have here is this is a red Key switch, which is the equivalent of a linear Red Cherry MX key switch. This is a black key switch, which is a stiffer version of the same It's just a linear press This is a brown much maligned and it this has a slight tactile bump in it So you can feel a little change in force as you click it and then finally we have a couple of Very clicky ones, which are the equivalent roughly of a Cherry MX blue I think I'm not sure where they're white Maybe there's a Cherry MX white that I can't that I'm not aware of so my favorite for typing is a blue I like those on my kind of regular everyday keyboard. That's what I use nice and clicky But you can see here one of the really cool things about this key switch is that by putting it on This little breakout that fits breadboard spacing we can try out weird stuff like this kind of ergonomic Keypad here, you might be designing a PCB for yourself or maybe just a 3d printed case or some other type of handmade case where you're just gonna wire these Directly to your microcontroller in this case. I've got a little itsy-bitsy M4 running this then you can create sort of unusual patterns unlike the typical grid pattern I don't have any of my other props with me here, but as you can imagine Here's my kind of everyday keyboard that is a very specific pattern of staggered layout. There's also ortho linear where they're more like a calculator keypads, but This allows you to get really wacky with designing some custom stuff And it's really quick and easy to work with you can also buy either soldering wires to the Pinholes or using some little socketed cables You can do very quick disconnects and add these into projects So One thing I'll say is if you want to head over to let's see can I get a Nice if I can add a browser window You know, I'm not gonna try because then I'll surely suck us into a black hole But if you head to the product page, and I'm just gonna tell it to you Which is product 4978 So if you head to aidafru.it slash 4978 Then you will go directly to the product page for this little Neo key socket breakouts And you will find that they are 50% off so they're on sale for 88 cents each Limit of 10 So if you have a project in mind where you want to do a little bit of experimentation with the key switches go for it We also stock Cherry MX compatible kale key switches. They are out of stock right now. I believe same with we have some of these nice little key switches and See through key caps, which are great for seeing that little neopixel That's sitting right on there So that is mounted underneath the solder tabs underneath and there's a hole cut in the PCB So the light shines up and through and that'll go through the hole on a regular LED key switch or even better use something that's white or translucent or transparent so that you get a lot of light shining through there But it'll it'll work going just up through that little hole That's in pretty much most key key switches that expect an LED and then you can use things like these Clear key switches again. I've got all my props in the workshop. So I can't show you some other ones that have What's called a little window Which is what you find a lot of time on scroll lock and caps lock keys And that also is like a little light pipe that allows that LED to shine through while the rest of its opaque. So it was really nice so Let's see what else to say about it. I can't bring up my code for it But the nice thing is this works like essentially two separate things. There's a string of neopixels so you can Follow the blue trace here this blue wire runs to the in of this key switch which is the Neopixel in and then it has an out pin on top Which runs into an in and an out and an in and out so that that's what that kind of blues wiggly wire is Then we have the powering ground for those neopixels I've put them plugged them in across the top and then down the bottom We have anode and cathode which are how we're reading those switches on the pull-up of different pins So I have five different pins that I'm using on the microcontroller to read those five switches however, like lady had said if you look closely at Those hide me these cameras like to focus on faces if you look closely there is a diode on there. There's also I think a resistor in in the Neopixel circuit, but there's a diode on there for the switch circuit so that you can do things like creating Column and row scan matrices if you want to use a lot of keys So a hundred and one or a hundred and four key keyboard that would be possible with these If you had a really odd design you want to get keys all over the place You can do that. You don't need a hundred and four iopins You need to use the scanning column and row matrix and I'm not sure what the limit is of those I haven't tried it yet, but that'll that'll be some number of Pins are required per set of keys So let's see any questions in the chat. I'm gonna pop over to the YouTube chat Fishy sir circuits asked will the key switches come in sometime? I'm sure they will I don't know when but you want to go ahead and sign up There's a little spot where you can type in your email address and say notify me Well that you know when those come in into stock These are compatible with Yeah, these are compatible with pretty much any Cherry MX Compatible key switch and you'll find lots of different ones available online if you have some particular needs and That's gonna do it. So Thank you all for stopping by sorry about the The weird stream. We had a bit of a disaster with my my computer that I'm now gonna go spend untold hours trying to fix possibly Swapping out a hard drive. Yay So that's the product pick of the week. It is the neokey socket mechanical key switch breakout and I'm gonna go inside and put it on my pegboard when I get back in there. Thanks everyone and I will see you next week
