 we love the news okay here we go first up first up we've got a this is a water flow meter and we already have one in the store but I really like this one because it's clear so you can see water moving through it or liquid these are not food safe so they're not used for like if you you know want to use it for potable water but they're great for like you know water-cooled PCs or if you're doing you know hydroponics or watering plants or like you know agricultural type projects or any other kind of like moving water around there is inside of it you can kind of see there's a fan and the fan has a magnet attached to it and then on the outside is a hall effect sensor circuit board and as the fan spins because water is moving through it the yellow pin on the JST connector on the outside pulses up and down I think it pulses like five times per or fifty times per liter per minute you know check the specs for the details but basically you give it about five volts power on the red and black wires and then you can read the pulses on the yellow wire that's a marguelo code to do that as well it's a really easy to use a water flow sensor and it's clear and who doesn't love clear electronics you want to show it on that runner yeah so this is so this is the body and then you can kind of see the fan on the inside and then these are half inch I think NPS thread so it's it's not truly one half inches just called half inch NPS but you can easily get adapters for this this threading to you know whatever you know a swage lock or whatever you've got and then over here you've got the hall effect sensor you can kind of see the circuit board and then the three pin connector that goes out here that gives you power ground and then signal out and the signal out is going to be I think zero to five volts you give about five volts power in right next up okay we actually have already stopped these they're called mechano wheels yeah yeah mechano wheels they're we've actually stopped them as individual mechanum wheels sorry yeah this is the mechanical mechanum wheels they we have sold them individually left and right however the factory was like hey we don't like you buying individuals left and right this is kind of like an updated product but it's no different than the existing wheels they're just sold as a set and then when we run out of the individual left and right wheels we're only gonna have these you tend to need them as a set anyways because when you make you can use these on put these on a robot and I see left and right these let you move the robot side to side or diagonally so you don't you don't have to just go forward and backwards and turn you can actually move side to side which is really sweet in which case you need of course four wheels two of each there's like that free throw robot from the Olympics that has these on it's it's yeah its legs and it was really yeah these are pretty cool now they're small and they're easy to use and they work with you know any they use they can work with either Lego cross shaft or TT motors so really common motors all right next up okay this is a seed shower add-on board but it also works great with the cutie pie because we made the cutie pie pin compatible with the show we thought it was a really good idea so this is a break-up board that you can see on the top left there the shower plugs into sorry the shower the cutie pie plugs into and then you kind of get like a bunch of hardware to attach to it I just kind of like that there's a little bit of everything so there's an on-off switch there is an RTC there is a 128 by 64 OLED there's a bunch of Grove connectors there's a piezo buzzer there's a user button and there's a lipo battery holder and lipo charger and on the back there's an SD card holder which you can use to you know store more files on I just think it's like it's really small it's really compact and kind of has a little bit of everything that you need if you want to put together a project so if you're going to use this with Arduino you can use either the RP 2040 or the Samdi 21 cutie pie if you're going to use this with circuit Python we kind of recommend going to the RP 2040 just because if you want to fit a lot of code because you're like I want OLED SD card RTC whatever all that stuff it's gonna be harder to fit that on the Samdi 21 which has a limited amount of memory especially if people just want you know the battery charging I think in the SD card it's it's quite nice this is the RP 2040 you can see it's running off of a battery and it charges over USB which is focus lock here's the OLED if I press the reset button here you'll see it use the OLED in circuit Python and it kind of prints out all the files that are on the SD card this coin cell battery holder is for the RTC and then if I remove the SD card and I reset again it'll it'll detect that there's no SD card I'll say a SD card so a nice little demo that just shows you have the OLED and then if I press this button it beeps there's a little buzzer over here so a little bit of everything one thing to note is that there is a reset button on the board but it uses the Pogo pin to connect and we don't have because we have a reset button on the board we don't have a Pogo pin for that so the reset button and the SWD and SWC pins are gonna work but a lot of people aren't using it for that purpose they're using it to like add all this hardware so it still works wonderfully with a QT Pi I think it's a great addition okay and then next up we have a whole bunch of keycaps and so what I'll do is I'll show these animated and then we'll show you kind of all of them yes this is part of a family we you can tell we kind of we got a whole bunch of animated sorry glow through keycaps yeah that we'd ordered a while so the back of all of them look like this and then we have an image yeah MX compatible and then we have an image of like a lot of these and I just have to say something well the hackaday ones are never gonna be available right because those are just a one-off that I did for this hack chat and then also I wanted to do it like 16 years ago so let's let's look at these okay so these designs are they're called they called Zener ESP you might be thinking like Zener Dio no it's actually a fellow named Zener who made these cards that they were used to maybe detective people had ESP now if you watched the most important movie that used these cards ghostbusters you might remember that there is like a scene I think Bill Murray is using these cars he's hitting on this woman and he's kind of like having her take the test and he's pretending like she's passing it and has ESP but these are kind of famous images the star the waves the square the plus in the circle and we saw these actually because they were featured in a church's video that features Robert Smith and so we were like that's really goth and esoteric and like why not let's do well the whole universe was aligned because it's like well we're doing keyboard stuff and now there's a Robert Smith video with a keyboard thing going on and then some folks pointed out already that this looks like the keyboard from aliens in the spaceship that they had not the little bit of the like fifth element you know yeah maybe even a little Stargate going on but it's cool but like we also have a to fruit open source hardware hack it a to talk yeah and we showed these off this is already in the store this is the open hardware logo and these of course are only available to the people who are at that hack chat who won yeah so you've got the star the square the plus and the circle and waves I just think they're kind of cool but kind of like they they're symbols but they don't have any inherent meaning which I think makes them really useful for keyboards because start could be get up stars it could be anything right because it's just it's just star and circle and square and plus so they're etched through they of course look best if you have a keyboard with backlighting but if you don't have backlighting else you know they still look pretty cool they're just kind of translucent white on black you don't have to get the full set but I think they were great as a set and they are cherry MX compatible so if you have a cherry MX or mechanical keyboard these will fit just fine okay and then this is one of my favorite products this week because it's an update it's an update because we've now shipped a box so that means that we can show kind of the the add-on pack that we're that we're stocking with the updated silk and more yes so when we initially sent out you know got the the macro pads ordered we didn't yet have the you know we weren't yet possibly be for eight a box so we didn't have the digi logo we also didn't have the artwork for the Voyager plate done we just weren't done but so we want to get into story wouldn't want to hold it up for this art but when we shipped eight a box we were able to get the art in and it's cool because it's got like the Voyager plate but like etched into the gold copper which I think I don't know it's kind of neat right yeah this is one of the and what's cool is when you assemble this it's not what you're displaying you know it's in there though you can either wait symmetric you designed it so you can you can make it so it's on the outside but okay so maybe it doesn't matter either way let's zoom in so I can show this the fact that you know it's there is what matters and like if you ever launch in the space maybe it'll help out with some future communication misunderstandings yeah this is cool so this is like the you know hydrogen like the distance between like hydrogen changes I guess or something and then this is like how many conversions is like the size of the thing and then this is like where we you know this is the Sun and then this is Earth and then this is Voyager moving out and then this is how big we are compared to Voyager so I don't know I don't know if aliens are gonna read this but anyways I think it's super cool so this is the the new artwork if you have the old artwork and you want to upgrade you can pick up just this kit and swap out the panels but it's it's mechanically exactly the same it just basically has the new panel art okay and star of the show tonight lady eight besides you our community our customers and the aid for team is we got an mcp 9601 breakout this is a thermocouple breakout that uses i-squared scene we've carried the mcp 9600 for a while the 9601 has a couple improvements it has it has some you know open and closed thermocouple detection although the errata sort of it says doesn't work super great and it just fix a couple of i-squared see issues that were in mcp 9600 so we thought you know if we're gonna turn that into a stem and QT board you might as well bump it up to the latest version but this is kind of the only thermocouple chip that you can plug in over i-squared see and it works quite well got Arduino and circuit Python code for it and then I can show the demo here so here I've got the sorry right so you've got the further m4 with an OLED and then I've got it plugged in here into into the mcp 9601 you can select it for any kind of thermocouple you want it doesn't have to be K I happen to like K thermocouples because they're inexpensive and common this is the you haven't plugged it into a thermal couple here and then as I put it between my fingers you can see it heat up I also have a little bit of warm water here I can put it in warm water and you can see it heat up even faster I will say that you know yeah you see it says like open and short this is in the errata the open and short detection is not really consistent if that's something you absolutely need I wouldn't necessarily use this chip I think they're still working on fixing that like there's a lot been a lot of changes in the data sheet in errata and this chip is pretty new that said for just detecting temperature changes for a thermocouple it works wonderfully it's really great for that and again it's i-squared see which means you don't worry about wiring SPI you can plug and play it and it works with every kind of thermocouple with about I think like two degrees C accuracy and pretty good precision so you know thermocouples you want to use them you want to connect to our i-squared see this is pretty much like the easiest and best way to do it so stomach you T plug-and-play and then just attach your favorite thermocouple to the terminal blocks here and that's new products
