 Okay, so this week new products let's start off with okay well we put in these Choco keys a few a week ago or two and now we have the keycaps to go with it I'll show both at the same time so maybe let's show the photos because actually that you can ever you can flip through all right so that the chocolate keys are they're not cherry MX compatible these are different pin out they're different size they don't snap into this they're totally different but they're really slim because the switch goes to the side not from the top and bottom and so you can't also the keycaps are different to the keycaps have like these two little nubs instead of like the normal cross shape I know it looks like there's a cross shape but actually uses these two little nubs instead but you know the good news is kale who makes the chocolate switches and we stocked the white clickies and the red linears they're also like okay well we also sell keycaps because obviously these are these are a little rare because we don't use the standard so we have clear crystal clear ones these are just really clear you can put LEDs underneath them I guess and you can maybe label them they work great with all the chocolate switches and this is what they look like from the top and they also have opaque black ones I kind of like these are they're a little chiclet looking very slim also like the clear ones they have these you can see the two nubs on the bottom the two nubs click into the chocolate switches and so you get clear or black these are like the really the two options there's also like a pale white but I didn't really like the pale white color so these are the two options for the chocolate switches I got switches are sold separately the keycaps so you need both here's our replacement overhead let's try this out yeah it works okay so yeah this is very very slim okay so that's chocolate switchcaps all right next up we did that one oh you already did this one I was I was no no no you're visiting okay so next up we have three things they're all kind of the same so I'm gonna talk about them all at once so if you're making keyboard stuff oftentimes people like okay I'm gonna use some acrylic or some PCB and maybe if I have a 3d printer I'll 3d print something but I noticed that I could pick up some enclosures and these are like kind of generic enclosures for keyboards now I'll say they're not inexpensive because they're milled aluminum and they're anodized and they have you know they're kind of custom-made but if you would like to make a four key or a two key or a four by four key key pad with either custom PCB or by free wiring you can free wire to these I kind of like these enclosures because they're like very well get their durable they look really good and then we you know again we don't have CAD files we'll try to get CAD files but we do have measurements that we've taken for you so you can design a PCB or like I said you can free wire it so let me show maybe I'm going to be creative yeah new overhead is new okay so this is just a demo of what it's gonna look like so you for these you do use Cherry MX switches and they snap in very nicely and so you get four keys and you see it is it is quite nice like it's a much nicer than having a raw PCB and then on the bottom here there's some have two screws some have one I'm going to know I know I'm gonna what are you doing well I'm just nothing is gonna stop us we are a gift yeah okay so I'm gonna open this up okay so unscrewing this it's I think our m2s so this is a plastic piece underneath you can see that there's a little bit of height available so yes you can have a PCB and the PCB will sit nice and flat there's little standoffs or to be honest you know there's enough room in here you can just like touch wire you know solder wires to the pads to a microcontroller and then just like tape it to the bottom of here sticking out and then you know it's you just have to glue it well enough or tape it down enough and then just don't yank on it but you wouldn't even have to create a custom PCB you could just use this as an enclosure and once it's closed up you know who knows who cares and on the side here you can see there's a slot for a USB-C or microbeat and let's show the two up one next yeah they're not all the same they're different in style but similar enough I thought I'd show these together so this one also has a screw an anodized aluminum it comes in black just two keys but you know like you said you just wanted a two key macropad one two one two I need that bottom has a key and then again you might have to bend that the pins a little bit but you you definitely have enough depth to that because I was one of the things I was gonna do is like switch different cameras but you know yeah you can't also nice little enclosure okay so that's this one so I put it to the side and then last but not least is the mega this one's really big I'm not to tilt up thank you for this nice yeah I constructed a overhead system and this is the four by four you which of course is gonna give you a full four by four keypad and this one is really fancy it's got like a flip top angle adjuster you know people like you want to adjust the angle and then also has a really nice big slot for USB connector for this one I think it's it's the key you know the cable is deep enough here you would actually you probably have the cable actually go in and just heart you know you just maybe glue it or something yeah but this one it's really it's quite hefty yeah it has a really nice feel this is a very fancy keyboard enclosure and if anyone out there does get one of these and you do do a model of this or you know what sized PCB you'd use do less no than the bottom you can you can see that there's a plate and then you just free wire inside we're also gonna have JP picked up one of our ortho pads and try it out and see if it'll fit nicely in here but this is this is this would be pretty sweet nice I really want this anyways so that's the two four and four by four anodized aluminum enclosures for making your own DIY keyboards all right okay the star of the show tonight besides you Lady Eda our community our customers our team and yeah do you want to flip to the in the ability to make overhead cameras yeah on the fly on the fly is the SCD 40 and 41 okay again everything comes in pairs today so this is a two for one so let's just go through and show all the pictures so there's the SCD 40 and then there's the SCD 41 and they look identical except that one has 41 on the top and one has 40 on the top why have both well they're there are two sensors of the same family and they're slightly different quality and so they're slightly different prices both of them are co2 temperature and humidity sensors that's right inside is a co2 photo acoustic sensor it's a true co2 sensor there's also a temperature and humidity sensor from sincerely on who makes a sensor all together and it's very tiny and cute and it has a ptfe filter on the top don't remove that white filter that you see that's not a you know that's not a pick-and-place tab that's a ptfe filter to keep your sensor from getting dirt and dust into it it passes it's not a screen protector that you should read yeah yeah do not do not remove that as we have learned say want to show the demo oh no let's keep going it's stick here so it's the sensors on the middle and it's a co2 true co2 sensor it is the next generation of the SCD 30 which you might be familiar with the SCD 30 is a NDIR co2 sensor which is really popular it's one of the few affordable true co2 sensors that can measure co2 parts per million in air and it's not an approximation it's the real thing the SCD 40 shown here I think it has 400 to 2000 ppm and then the SCD 41 which again looks totally identical is 400 to 5000 ppm now most humans don't live in anywhere near 5000 ppm I think you'd actually get kind of sick at that point so the 5000 up to 5001 that's what you would use for you know industrial or scientific or or some other environment where it's like it's in a machine or something it's we're not humans are not and so you have to measure above 2000 but if you're just doing you know the most common thing which is you want to measure indoor co2 sensing for you know is there air how's the air quality is there airflow are you are you making sure you have enough oxygen the SCD 40 will do a perfectly fine job that said if there's a shortage the SCD 40 is at a stock the SCD 41 is just that much better so let's go to the overhead I got a little demo here so like many of our sensors it's I squared C I gotta adjust this yeah this is fine we're homemade overhead so this is okay so this will work out oh no live demo hold on there you go why is it saying 114 ppm right it has to wake up it takes it takes a little bit of time to wake up but the SCD 40 we put it on a stem and QT board so it's got the sensor and then on the side you've got the plug-and-play I squared C connectivity so you can use it with Arduino or circuit Python I wrote the circuit Python library it's pretty straightforward or the Arduino library actually comes from Syria on they published their own library which is great and you've got humidity 49% you got temperature you know 28% or so and then the ppm I breathed on it so it spiked up pretty high but this will measure I think once every five seconds again from 400 which is outdoors you know 400 ish to indoors are going to get up to like about a thousand again maybe up to 2000 if it's a little stuffy indoors but why use this instead of the SCD 30 well it's a lot smaller for one you can fit it in more spaces it doesn't I think it uses less power overall unlike the NDIR which I think has to like heat up and do a lot of work this one is much smaller and lower power and it can even go into the SCD 41 can go into a low power mode so basically you know SCD 30 does the job it's reliable people really like it but the SCD 40 is the new generation and especially if you want something wearable or small or portable this one is much much tinier than the SCD 30 and it works just as well it's got everything same built-in but much more compact and we have it plug-and-play with Python and Arduino support so it's great for adding air quality sensing to your project and those new products
