 FidgetKey and AidFruit present. This week's IonMPI is from Antimatter Research. What is this, Ladiator? Yeah, this is pretty cool. They've got a great name and also an awesome logo. This is a bunch of cool hackers who do product development and they came out with a product which is based off of the XMOS DSP system for doing audio pinpointing. Like you can do far-field voice DSP work to make it easier if you do voice recognition. I thought this was really neat because usually these kind of dev boards for voice recognition assistants are really expensive where you have to roll your own. But this one kind of comes ready to go, which is really nice. So here it is. This is the Accusis-S from Antimatter. And it comes as just like a long, flat PCB. There's lots of mounting holes and there's rear-mounted microphones. We talked about I2S and PDM microphones a couple of IonMPIs back. And what's kind of cool is that there's this rear-mount USB at the top you can see in the middle. The rear-mount USB, you plug it into USB and it just shows up as a stereo microphone input. But that stereo microphone input is actually taking the audio from four separate microphones and like doing audio, far-field DSP calculation and filtering on it so that it's going to work really well with your voice recognition software. You know, there's, you know, as a service, a service voice recognition systems out there like IoT services that you can take audio clips, send them over the cloud and, you know, get speech to text back. Or, you know, you can try to figure out what people are trying to ask you to do based on like certain commands that your product or project may have. But one of the hardest things about audio is unlike video where you can usually just add lighting or like control where you're, you know, you're doing your vision recognition. And audio, like you can't add anything to make it easier to hear. You have to subtract, which you can't really do because you have like, you know, microphones and humans and you've got traffic and you've got people loading the dishwasher and you've got the air conditioning going off. So all of this like background audio makes it really hard to do audio recognition well. And so if you can do any kind of edge processing, that'll make your results much better. So XMOS came out with this chip and this is like an all-in-one DSP chip that I guess you program it and it has built-in support for four microphones. It's called the XMOS XVF350DSP. It also has some Philips B-Clear technology, I guess, inside of it. And you kind of hook it up to the microphones. I guess you can program it probably to do any other extra calculations or filtering you need. And then yeah, it shows up as a USB device, which is pretty sweet. So this is the chip. And of course, you know, this is kind of, think of this as a dev board for this kit. If you're making less than a thousand or maybe 5,000 of your final product or project, you can definitely use this dev board just as is. It's plug-and-play, use it. It works with Mac, Windows, Linux. They have a couple of demos with Raspberry Pi. So it definitely will work on low-power single-board computers. And then you can also check out XMOS if you want to program this chip with more custom calculations that you may need for your product or project. I think that's if you get to like the 5,000, 10,000 plus units. That's where you'll want to do it. But as it comes ready to go, you don't have to sign any NDAs, which I thought was really nice. You just plug it in and it works. I have one here. I thought I would just really quickly show it off. It's kind of neat. I like some of the details here. So let me back this up. So this is the front... Wait, we'll have to show the whole board. So this is the back. Thank you. So this is the back. So you can see there's this like plug-in USB. There's also a microphone input so it can do echo cancellation. If you have a microphone as well as... Sorry, if you have a speaker as well as a microphone, that way your microphone inputs can have echo cancellation based on what the speaker is also playing. Over here you've got one, two, three, and four of those PDM microphones. And they're panel mounted. There's a little programming header here if you want to reprogram. The XMOS, and this is probably some more GPIO that's available. Power supply over here, more mounting holes, maybe configuration and I don't know what this... Maybe USB interface. And then on the front, what's cool is that there's these LEDs that tell you what the XMOS thinks the current audio location is. Like it's a far field. It can detect where in the room it is. So right now I'm right in front of the microphone, so the middle LEDs are going off. But then maybe my gracious assistant could say something. Hello. Hello. So you see how the LEDs when my great assistant is speaking is over here on these LEDs. And if I move over to the side, it can detect that my audio is coming from the side. And then I'm over here. Yeah, there you go. All right, so we're a team. But normally I'm right in the center here. So yeah, that was a really cool little dev board. It's ready to go. I mean, it's definitely a demonstration of this chip and its capabilities. But if you don't need anything more than the default demo, then this kind of comes ready to go. And you don't have to worry about this ridiculous like 5,000-pin BGA chip. All right, so check it out. That's the Q-SYS 7 from Antimatter Research. We looked them up. And like Adafruit, they have a team of people and they do cool videos of things that show a little bit behind the scenes. So here's the team doing a time lapse. Kitten, kitten. Of putting them all in the boxes and more. They also have a great video of the test procedure. Often when you're sending out your boards to your fabrication house, these are not going to be this kind of board you can't manufacture with just a toaster oven because the pitch of the BGA chip is just so fine. So they sent them instructions on how to test the board. And it's actually really handy if you've never sent out a board to a manufacturer, you might want to check out that video because it's a really good example of the kind of information and step-through that you'll want to give your board house so when they manufacture they can test efficiently and get you the best yields. And this was an unboxing of the product. You can see a little demo, show how it works on a Mac here. And we also found a video of one of their team members showing it off and all the things it can do. So I'm going to show that next. Hi, everyone. I'm Gladys from Metameta Research and we made a microphone that is perfect for ASMR. You can hear me back here at a whisper. You can hear me from here at a whisper. Imagine all the ASMR possibilities. And like all NPIs and all the roads lead to one place for NPI for new product, Digikey. It's on Digikey site. Yes, and they've got a couple hundred in stock. I picked one up as I've got plenty. You can definitely see the engineers having a really good time and they're also available for consulting. So if you want to integrate this kind of technology into your final PCB, you can hire them and they'll definitely be able to help you out to get that board fully integrated into your own PCB design. So check them out. Metameta Research seems like a fun group of people. Yeah. Shorturl, digikey.com, short, Z112NF. And the part number is 2850ARAC S1ND. And you can also search for, what's the best term? Accusis. A-C-U-S-I-S. Yeah. S. So we do a segment about great search how to find stuff. Yeah. So that's what you search for. Yeah. And you can see here's all the places it lights up. Hello. Obviously robotics, fun, you can, I mean everything has like a voice thing for now. Yeah. So. Okay. This knows who's speaking. It's actually kind of cool, right? It can do like pinpoint location of where the audio is coming from. I know. Cool. All right. You can play with this all day. All right. So that is this week's INFEI. INFEI.
