 And welcome to Lady Aida. Hey everybody, and welcome to the desk of Lady Aida. It's me, Lady Aida, and here I am at my desk. Gonna get some fun stuff to show off today. Got some interesting chips. We've got some cool turntables. And of course, you've got the great search right after. So do we have any updates or news this week? First off, I just wanna say happy Easter, Passover, Romanon, whatever you celebrate, whatever it is, hopefully you're coming together and sharing some good times. Good food. And we're here together now. So this week, normal week of shows, I think we have JP guest host for show and tell. And kicking off desk of Lady Aida is probably one of the most advanced, interesting record players that has so many forward thinking things that you've probably never seen and heard about before and we have one. Okay. So Lady Aida, why don't you show off the Sony Flamingo. Okay, why don't you go to the overhead and we'll do a tour of this thing here. So this is the. That's a record player. This is a record player. Not a CD player. Some people saw it online when I posted up a photo and they said, is that a CD player? It looks like a CD player. We're gonna play a live record, a pink record shortly. So you can actually kind of see there's this long slot and the record goes into the slot and it stands up. It's called the Flamingo. It can stand, it can actually be played vertical or horizontal. It has a tracking and direct drive. Flip it upside down and show the bottom of it because one of the things I think people don't, who've seen these don't realize is on the bottom of it, there's these little legs. Some folks say, oh, this thing's gonna flip over. Now go to the other side. Yeah, so show that. Tilt the camera up a little bit. Yeah, hold on. And then. How do I do this just now? Yeah. So this flips out. Yeah, now it's really solid and it won't tip over. Yeah, this is like the coolest part. It's like a very. It's one of the coolest parts. Okay, and this is power. You can battery power it, you can power it from six volts. Yeah, it's portable. You can see, which is portable. Also on the back, show the little hook. So this is meant to also be mounted on a wall. You can also make it portable. You can also wall mount it. It can lay horizontal or vertical. And here's little rubber bumpers to protect it if the wall, so you can, you have like two mounting slots. Yeah. It can play 45s or 33s, volume, two headphone, audio line outs. Yeah, and it says record, which is interesting. No, for recording to tape. I looked at the manual. Yeah. It doesn't, obviously you can't record to a record on this. No, of course not. Record is, they encouraged on the hardware to tell people to record things. And then one other thing that Lydia will talk about, it actually, some of these did wireless broadcasting, but there wasn't such a thing as Bluetooth. Yeah. So we'll talk about that in a bit. We'll do that. Okay, so you want me to show this off? Yeah. And this is the front. Yeah, so why don't you move the record out of the way, stand it up with the, put this little leg out. Put the legs out. Okay, hold on. And then we're gonna go to the other camera camera. Okay, gonna put the legs, legs. Yeah, so show it, show it how big it is compared to Lady Aida. There you go. And then we've got another cam view, just so you can see it. It's like one frame per second back off. Okay, so hold on, let me get this out. Yeah, I think I'm gonna go to the other view since this web camera ain't so great. Yeah, that's okay. This is the pink record. Okay, hold on, I'm gonna put this aside, so then I'm on side two to face out. Okay, so the record slots in. Yeah. Oh, and then, yeah, it sits nicely and then there's a little. Yeah, you can maybe move it back a little bit so it's more in camera frame. Yeah, there you go. And then this is the. You lock it. Lock it, and then I'll show up here. I'm gonna press play. And we have it plugged into a Sony speaker. Yeah, so I'm just holding it. I'm gonna put it down so it's more stable. It's okay, we can hear it. Yeah, yeah. Okay, all right, so this is a good ambient music for us to talk about. I'll go to the side of the speaker. So that gives you an idea of how big it is. Yeah, and it's cool, it's like you can see it spinning and it's just hanging out here. Yeah, and hold up the record for the camera in front of the record player. This is the Blade Runner soundtrack on vinyl. Perfect record for this particular record player. Now, when we were looking at this, there's one for parts, one that works. These are really hard to come by. Some of these allow you to transmit the audio wirelessly, so you can go ahead and stop the record. Stop the record? Yeah. Oh yeah, and inside, it's hard to sell, but inside you can see the little thing. Yeah, and then let's take the record out. Release, you can take out the record. Yeah, I'll be off stage prop. But you can be prop manager. All right, what do you want me to do with this now? So you can unplug the power and the audio. I'm gonna flip out the legs. Yeah, okay. And then if you put it on the overhead. Yeah. So right in the middle, and you can't really see it between the screen, there's a little dot behind all of it. Yeah, maybe you can. See where it says it's a Sony? And I could see it on the projector. There's a little dot directly above the orange dots. And yeah, right there. And that's where some units had a FM broadcaster. And that is what we're gonna start to talk about real soon. Well, I mean, I don't have a lot of deals with a broadcaster, I could show the webpage That's what we're doing. Right, okay. I was like, okay. Well, this one doesn't have one. I didn't build the FM broadcaster yet. Some do, some don't. So I'm gonna go to the computer. Okay, so this is a webpage about the Sony and it has some stuff and it talks about the F9. I don't know if this is the, this is the F5. So the F9, I guess, is the other version. And that one had a little hole in the back that you could use a screwdriver to adjust the FM transmitter. So FM transmitters, I think weren't legal, even low-grade ones until like about year 2000. That's because everyone was using iTrips, do you remember iTrips? Like you plug it into your MP3 player or your Walkman and you would transmit it to your car stereo system. And they're saying that's kind of what made it legal but it was basically around 102 megahertz FM. And then you would be able to you'd be able to listen to it on your stereo system. You know, even if you didn't have audio out or I don't know, I mean like I don't see why you would, I mean it is battery powered but I don't know if you would necessarily take it somewhere and like. You would absolutely put this in your car. In your car? Yeah. So the interesting thing is when you think about like what happens with modern electronics now that play some type of music, usually they can use Bluetooth and transmit that audio to something else but Sony at the time, they had this really clever thing which was FM. So if you think about what this could do, this was a record player. It could go horizontal and vertical. It could broadcast on FM. It had audio out. It could play different types of records. Battery powered, hanging up on the wall. I like the hanging up on the wall. That's kind of cool because it's like. And they published the schematic at the time. Yeah. This is the dev, sorry, the service manual. Yeah. So one of the things, the official name is like PSP5 or whatever. Yeah. So, you know, one of the things I'm gonna do is post up some photos and video and I'm gonna say like, hey Sony, like what are you reissue stuff like this? Like this is the Sony that we all miss. This is the Sony that a lot of people don't even know about. The sales of vinyl go up every year. This would be a really interesting reissue with some modern electronics and instead of FM or keep FM in there, put Bluetooth. Yeah. But they even have the board layout. Yeah, no memory stick though. We don't have a memory stick. This is manually routed. And so like, you know, once in a while, some folks say, oh, open source has been around forever because back in the day, I used to be able to get schematics. Sure. And okay, so what happened? Why don't they have it anymore? We'll be able to always repair this thing and always keep it for, you know, hundreds of years. Literally. And so this is why we thought it was really neat to show and share because do you really get something like this when you buy an iPhone or the latest Sonos player? Do you want to get a replacement cabinet lever? Like they don't, obviously they don't stock these anymore but this is, this is funny. Like, you know, they use to be able to get replacement. Like that's not, there's no such thing anymore. Like you can't get like replacement. Yeah. Oh, it does have a needle by the way. That's how it works. Oh yeah. It's, I mean, circuit player. There's a needle inside. Yeah. We're not going to open it up to show that because it's protected by dust. But yeah, you can see, these are 2SC2458 transistors. They've developed all the transistors. So you can, you can theory, you know, place the transistors or the resistors are labeled. Yeah. All right. So 1983. 1983 was a good year. And one of the most unusual, cool, interesting kind of did it all right on the cusp of when consumers of things didn't really get to do what they wanted with hardware. Like that's, that was like the beginning of the end or the end of the beginning, however you want to look at it. So this FM piece though, what if we wanted to do something like Denali, you know? You know, we would use, you know, we'd use a FM transmitter chip. We actually have one in the store this size, 4713, I think. So, you know, if you wanted to update this, you know, there's also off the shelf audio to Bluetooth audio adapters. And I think even ESP32 has an example of like, you know, one of the demos you can do with it is turn it into a Bluetooth transmitter. So, yeah. I mean, like these old technologies, they can be updated, although, you know, I kind of do like audio cables. They work. They work. Okay. All right. So let me show up some other stuff. Okay. I'm still on your computer. Yeah. Okay. So some other things that I did is, oh, you know, we have this a piehole kit that we've had in the... No, not this one, but I thought we had a color one. One second. Yeah. We had a kit that you could put together to make a Raspberry Pi ad blocker project. And this was a really popular project that people like to build, but you can't get pi zeros anymore. And even if you did a lot of people, you know, it's hard to get all the parts in order to make this project. So we wanted to make something similar because a lot of people like to build products. It's a common thing. So we made a version with an ESP32. So we can go to the overhead real fast. And JP will be doing a project to document it, but that's called an ESP hole. And, you know, it shows the IP address. You can kind of barely see the text. Blocked 731 out so far. Yeah, hold on. There you go. So it shows the IP address and how many domains it's blocking. The only thing is it can't store like these three megabyte ad block collections like the pihole does. But, you know, I have this set up with 7,000 domains. I kind of use this, you know, there's this ad aware network. They have a 250K list of domain names. And I loaded it onto here. So, you know, that's the computer. I basically forked this project called ESP32 ad blocker. This project actually works quite well, but it doesn't use the TFT screen or mass storage. And what I liked about this project is, you know, I made it so it shows up as a disk drive and you can see all the domain names and you can set the configuration. So, you know, the SSID and password. And then the TFT is really nice because one of the most annoying things about making piholes is that every time, you know, you can't use a domain name for it. You have to use an IP address because it's your DNS. So it has to be, you know, referenced by IP, but if you don't know the IP, how do you know it? So having a TFT screen is really handy. And then I liked that it says how many ads it's blocked. So, you know it's running. Didn't know that ESP32 could work as router will expose to networks. Yeah, this connects to one network only. It's on the network and it's acting as a local DNS, just like the pihole, which also it doesn't, it's not a router, it's just a DNS server, which, you know, when one of the hosts that it gets queries for is, you know, whatever, swerve.com, I guess it's an ad network or adcolony.com, it'll just say, oh, you know, that site doesn't exist. And that way you just don't, you don't serve up any content from those. Also good for malware blocking, so not just ads, but like crypto miner networks or malware sites, it'll block those as well. So you can get, you know, it's useful for not just for ad blocking. And of course it's handy when you're on mobile because mobile browsers don't have that kind of blocking capability built in. You can't have an extension like you can on desktop. So I use this on like my tablet, like when I'm, you know, in bed and I'm reading, just keeps me from like clicking on like ads or malware. So that's one project. And then I'm looking at some fun chips. One thing I saw is SparkFun has a library for this magnetometer. And we talked about magnetometers a week ago and I actually didn't see this during my search. This is a high precision magnetometer, but I really like the look of it. So I thought I'd also make a breakout. This is the MMC 5983. It's an 18 bit magnetometer. So I think it could be really useful for very precise readings. I think once in a while people really need a very high quality magnetometer for, you know, measuring earth field. So made a little stemma, cause it's stemma Sunday. It has iSquared C and SPI, which is another thing I kind of like. The other one was iSquared C only. And let's close that. Yes, save it. The ad blocker. This is that magnetometer. Lots in stock. So this is an addendum I think, you know, three weeks ago I was talking about this one, but it has about plus or minus one militesla. And then it's three volt logic and just iSquared C or SPI, but one kilohertz bandwidth and 18 bit resolution. So a very nice, very nice magnetometer. And this is another chip that I saw. Let me close this. That I thought was kind of interesting. I saw this on a cable that was like a USB PD cable. And I thought that it was, it was an interesting design. I'll show it later. I'm getting a sample. It's a cable that plugs into USB-C and then has a DC jack on the other end. And inside is like a little PD configuration chip that says like, hi USB-C, like I want you to deliver me nine volts or 12 volts or you know, whatever and certain current ranges. And so, you know, I was like, oh, what's the chip that they use? So it's the H USB 238. And you know, what I like about this is the utter simplicity. You know, you just connect to USB data and control lines. There's a little VIN detect. There is one past transistor, but that's a good thing. You definitely want to have something to be able to enable and disable power. And then you can set the voltage and current desired that you wanted to request over just setting a resistor, which is like super easy. So you just like, you know, you can either twist a resistor or solder one in or there's I squared C. I thought that was kind of interesting. So there's two ways to set it up for configuration, which I kind of like because usually over, I don't know where the I squared C, I think I found the I squared C register map elsewhere. But here's the I set current in the V set. So you can, these are the common resistors. So, you know, you can select between five different resistances to set five, nine, 12, 15, 18 or 20 volts. Just another nice thing, I've seen other USB PD chips, but they don't have, they're like, oh, we only let you select five, 15 or 20. You know, they don't let you set all the different little voltages in between. So I kind of, I thought it was cool that this one would give you a range of resistances. So that's the chip. So any questions about that? Can the MMC 5093 detect magma displacements? I don't know. I've never had to measure magmas. Okay, cool. All right, so, magmas. Okay, so let's go to the great search. We'll talk about what chip I'm looking for this week. All right, that was a great search? Yes. The great search brought to you by Digikey and Adafruit every single weekly day to use the power of engineering to help you, you, yes, you find things. You? That are hard to find because we're in a global part shortage. I know. Hey, Adia, what is the great search this week? Okay, this week, I'm actually working more on the feather wing that I started last week. Last week, the great search was on finding an RS232 transceiver chip that would take TTL logic at three volts and convert it to plus or minus six volt logic. And so we sourced apart the next 3232. I think it's wonderful. It's available in a couple of different packages. It's in stock. So check out last week's great search if you're curious. And then this week, so as I was working on this, I was like, you know, one of the things that we've had requests for is not just an RS232 wing, which I'm designing, but it's also reminded me of an RS485 wing. So RS232 is TTL serial, but with very wide voltage range. So instead of having zero to three volts, it's like plus or minus six volts. So it solves the problem of like how to get this signal very far by just making the voltage four times larger, which is like a totally valid way of doing it. For RS485, also known sometimes as DMX, does it a little differently. Instead of just making the voltage swing higher, it does a differential signal. It's a little bit like CAN bus. So, you know, for RS485 is used for industrial purposes. Again, it's also used for DMX. It's like a multi-tap system. It's like, it uses TTL, but it's a little bit more going on. And I thought, you know, let's go to the computer because I'm just new computer stuff. I thought that I had so much room, you know, here, because it's, ignored this Adel Lager, some Adel Lager, I just recycled the Adel Lager layout. You know, I was gonna have the RS, sorry, the DE9 over here on the edge. You don't have this hand soldered, but you know, that way it fits nicely. And then a terminal block over here with RX, TX and ground. But I have a lot of space left over and though I thought like, oh, I can make this be like a combo because, you know, a lot of times if you're using RS232, you know, you're often also interested in RS485 because you're just like, how can I have this long distance serial transmission? And so what's interesting is I actually, oh shoot, I, hold on. I want to look up the, let me see RS485, yeah. So it's looking like RS485, I actually saw this design from TeenySign and I'm like, oh, this is kind of what I want. It has, you know, you can select RS485 or RS232 and then there's, you know, this SP232X or something here and then there is the adapter chip here. This is a Max 461 and then you can see that it's like, you can have one or the other and I thought like, that would be pretty handy. You know, you'd have a switch to enable or disable either chip, maybe disconnect it completely. And also, you know, if it can't necessarily use both at the same time, although, you know, just because of the voltage, I don't want to necessarily mess up the voltage outputs. What I could do is, you know, only pick and place the parts for one or the other that could also be a design because it would be like so similar. And again, I have that space, I might as well maybe make a design that can do either or both. So this is kind of interesting and inspiring, but what I need is to get a transceiver. Now, the thing is I've never actually used RS45, so I'm gonna have to pick up something that I can use as a, like the other side, I'll have to pick up some DMX light or something whereas I showed you last week, the space ball has RS232. RS232 is like kind of everywhere. That's very easy to get. RS45, I don't have anything, but it's a common request. And so I think it's a worthwhile thing for me to add on. So RS45, you know, there's a Wikipedia article and it's basically a, you know, instead of, instead of a single, you know, one for you, RX1 for TX, there's bidirectional, sorry, differential lines that go up and down. And that's how they, you know, they also have idle where they're both sitting at zero volts. There's no, there's like negative, positive, and zero. And so you can actually have the bus be shared. And then for DMX, I just want to make sure that it's more than 250 kilobit per second, but it looks like it can go up to 10 megabit per second. So when I went to Digi-Key, so the good news is that if you like search for RS45, there's a ton of converters and adapters and there's also the transceivers. So to start with, one thing that was interesting actually is there is some chips that are both RS232 and RS45. They tended to be more expensive. So if I apply, you know, I did look and I was like, oh, that's interesting that there's combo chips. Like somebody else had the same idea of like, oh, like why have one and you can have two. The problem is that the chips, like, you know, they look amazing. This Max 3160 is super awesome, but it's 12 bucks a piece. And while I'm sure it's absolutely worth every penny, it would be kind of, I'm like, I think I have enough room. I think let's just have two chips and let's do it that way. So I ended up not, you know, I ended up not wanting a multi protocol. I'm just going to select RS45. And then there's isolated, well, let's first pick active only because I only care about chips that are currently available. And then there's driver, receiver and transceiver, which I don't really know the difference, but what I do care about is how many drivers, receivers. And I want, I don't want to have just receiver, I just want transmitters, I want transceivers. So we'll get the one, one and two, two. So it's like either once, you know, RX and TX or two TX, two RX. Like we showed with the last week, we had a two, two RS232 transceiver. So there's isolated ones. Again, I'll show that. I did look at these real briefly and these are cool. They're all out of stock and they're a little bit more expensive. But I did think it was, you know, it's something to look into if we can eventually get them in stock. They're a little bit bigger. They're 16 SOIC and they're also completely unavailable like most chips, but there could be some purpose for an isolated RS45. So I was like, okay, that's interesting, you know, I'll keep that in mind. So looking at just the RS485 non-isolated transceivers, we also only want surface mount parts because I'm not going to solder through hole. For the data rate, I do have to make sure that it does 250 kilobot or above. Looks like it goes to like almost infinite. Basically, I just don't want the ones that are guaranteed to be slow. Just wasn't that many. And there's still a lot of options. So I'm going to go for only ones that are normally in stock and in stock, like ones that are stocking and available. And that gets me down to, you know, I think a couple hundred options. And then it looks like, you know, a common, there's like a jelly bean part layout that's an eight SOIC. It kind of, I looked around at some other RS485 transceiver chips, like setups and breakouts. And they also seem to use like these eight SOIC because it tends to be just like one RX and one TX. So while I may change my mind later, I'm going to kind of go with this standard eight SOIC package. I'm going to select that. And the reason being that, you know, these transceivers, like can transceivers, it looks like there's a lot of makers that are all kind of the same and it's a very generic part, which is good because it means that if it's out of stock, one, you know, from one supplier, I can switch over to the other. So I kind of want to stick to this kind of standard layout. The next thing is whether I want it to be half or full duplex. And to be honest, I'm actually not sure, but I think I want full duplex because I want it to automatically transmit and receive. Although I have to look into that because again, as I'm looking into this, it's like, oh, there's all these little like, it's like, it's so simple, but there's all these little details, but for now I'm just picking full duplex. And another thing is for voltage supply, while I could have a little boost converter, it would be cool if I could get it working off of 3.3 volts because that way I wouldn't have to add an additional, you know, boost converter. And this part kind of came up first, so it has the most in stock and the price is pretty inexpensive. It's one of the least, lesser expensive ones. And I'm always into like anything that has over 10,000 pieces in stock is kind of like a good sign for me because it's like, oh, this is like a standard stocking part. A lot of people use it, so you have to have a lot of them in stock. So I'm going to start with the ISL 8340 490. And this part, I can open up the data sheets. Data sheets. It's a 3.3 volt supply, but it's five volt tolerant. And it can go up to 10 megabits, so it's high. Data rate, it was designed in 2018, so it's kind of got a more, you know, it's more, there's a couple that are older, but that's a fairly modern date for something like this. And it looks like they have a couple of variations. So they have versions that are slew rate limited, that have low power shutdown, looks like basically you can either have full duplex or low power shutdown. You can't have both, which makes sense. It's like, if you're full duplex, it means that you're kind of waiting for signal. You can't really go into low power mode because you're waiting and listening. Whereas on half duplex, you could tell the chip, hey, I'm not waiting for a message, so like go into power down and I'll tell you when to listen for getting an idle. So it looks like there's a couple options there for this chip, but they're all this kind of standard SOIC. This is the half duplex and this is the full duplex version. So I don't know, it looks pretty good. I basically have to look into, again, whether I want to get this, you know, what's more important to be basically having a half duplex, low power, controllable or full duplex. It kind of does its own thing, but you don't have to switch between one or the other. I don't know which wiring set up people tend to use more. So I'll look into that and hopefully I'll pick which sub-variant, but this family looks really good. And of course I love Intrasil and Winneshouse, they're a great chip maker. So I'm feeling pretty confident with my decision. So I'll get some samples. I'll start working this into the design and then when I do a prototype, I'll pick up a DMX light or something and I'll try to just get it working or I'll just build two and I'll try to get signals transmitting back and forth. That's a great charge. Okay, some questions and then comments. Could that be used to charge, quick charge a LiPo, start five volts and increase the voltage when you're charging? I think that's for your design that you're charging. No, you don't want to do that. It's more for when you have a chip or device that needs a higher voltage because of like power requirements. Okay, Bill says we'll move one of those pins far left second row from the top. I'm sure she'll notice, but if I don't mention it, I'll feel bad. Oh yeah, I mean, it's a whole mess. Okay. It's not ready. I noticed that the one you chose with tube, not tape and digireal, can your pick and place work with the individual parts or will you just find one with tape stock? Oh, I forgot to mention, there is a version that has tape, but it's like you have to order a full wheel. So I'll probably get samples in tube. Our pick and place can use tube or you can send stuff to be tape and wheeled from tubing. I would do that all the time. Okay. Like at this point in the silicon shortage, you get the part in whatever package and you'll deal with the consequences later. All right. And as always, if folks want to support Adafruit, go to Adafruit.com, pick up some electronics and more. Pick up a TFT feather wing and you can build this ESP whole project. I've been using it nonstop. It's been super fun. Okay. And that's the Descalade you did this week. All right. Thanks everybody, team in this week for lots of live shows. See you next week. Bye.
