Hi, welcome to everyone's favorite segment: Mailbag Yes! I'm inundated yet again. this is not all of them. I've got another three there I've got another couple down here and well, a whole bunch of them and obviously I won't be able to get through them all today. Sorry about that.

Um, but yeah, hopefully next week are being busy the last couple of weeks. For those who've wondered why there's been no mailbag, so sorry about that. I'll probably go through in the order that I got them. so the oldest ones are first except for this one down here which is your brand spanking new product from Fleur Yes, Fleur just released like yesterday so we'll probably open that one first.

Let's go. haha Yeah, by the way, I have tightened the shot up on this I've got the camera closer and sort of down a bit more. people wanted a tighter shot on that so hopefully this isn't too bad. Let's go.

So yes, a brand spanking new product from Fleur And yes, it is a thermal-imaging camera. or well, kind of. We'll see it is brand new. It was released yesterday.

it's a twenty night here in Australia today I Believe it was, or at least on like the 27th probably should have taken all that crap out. Um, so it is brand spankin. I Haven't looked at it yet. Tada Here it is here we go.

Tada. It is the Fleur Tg165 and it's a it is a thermal camera, but it's more of a visual thermometer kind of thing like flukes. VTO - and VTO for thermal thermometers. It sits in the market between there I flew one of course for the iPhone That's all the rage at the moment in terms of price point and functionality.

Between that floor one add-on and/or and the flurry four camera that we've looked at I've got the E8 but the bottom base model efore. So this is four hundred and ninety nine dollars, five hundred bucks and the only thing I don't like about it I haven't even counted up yet. but I know for a fact it's got the Re4 type form factor which is really quite nice I love that and it's rugged and drop proof and everything else, but it doesn't have the MSX technology and that that is the difference. I'll post a link down below to a table that Fleur have highlighting differences between this Fleur one for the iPhone and the E4 model.

Yes, it does use the new Lepton sensor same as the Fleur one, but it doesn't have the camera in it for the MSX overlay which is quite disappointing. but if it did hey, it'd become a flurry for so they're positioned it between that market priced about halfway between at 499. But it does have the laser thermometer so it doesn't read the temperature from the Lepton sensor. it actually reads it based on your traditional laser targeted infrared thermometer.

So it's combination of between a more niche market than either the Fleur one or the for for a full thermal camera. So it's almost a full thermal camera. It's got that Lepton sensor in it, but know that MSX technology which is fantastic. So hmm and this is what you get in the box.

the camera itself of course, which looks and feels very nice. You get a USB and charging adapter with all the requisite adapters plus a USB cable. but interestingly, the voltage on this thing is five point three five volts at two amps. so it's almost as if they have catered for like a day.

And I can then presume that you're going to get a drop in in the USB cable, which you probably will of course, especially at two amps. but still, that's quite unusual to output five Point Three five Volts. Hmm. so here's where it stands.

It is a combination between just your traditional are you know spot IR laser thermometers like this. The laser is just a targeting based system, so it's got that. but it also overlays a uses that Lepton thermal Imaging sensor to overlay the image on there, but it still reads as I said the temperature based on your traditional pyroelectric sensor in there doesn't get the temperature readout on-screen as we'll see from the actual Lepton sensor. and in terms of you know size and functionality for it.

This is the Fleur Eight which is a fantastic thermal camera, but the E4 is exactly the same as this, so it sits somewhere between there, but it's much smaller, much lighter. It's got an 8 hour battery life rechargeable. USB Yes, it does have a tripod mounting thing on the bottom. Why they couldn't do that on the on the E-series I Don't know.

Well, because the E-series actually uses these nice rechargeable battery packs. This also has a infant. It's got an internal rechargeable battery, hence why I Guess they could put that, but ah jeez, they should have added it. Real pain in the butt.

Anyway, so it's it's somewhere between these in terms of our price and usability. As I said, no. MSX Technology like the E-series Now, if you have a look at the front here, you can see we've got dual laser diodes here I'll show those in operation in a minute so you can actually get the spot difference um, at a distance, which is really quite handy. And then we've got the thermometer window here, which curiously isn't your traditional or doesn't seem to have like a traditional Fresnel lens like it does here.

So maybe it is inside and that's a a thermally yaar transparent window? I'm not sure. And then we've got our Lepton sensor up here. so our lepton devices behind that. So as and as I said, no camera because it doesn't have that camera overlay that MSX technology, which is so wonderful on the E1 and also is fairly useful on the Fleur one as well.

And on the top here, we've got a USB interface for charging I don't know if our video comes out of this thing I'm not entirely sure and a little micro SD card there for saving images and no it can't save video or can do is take our screen shots with the trigger down here which also activates laser and those photos of course are done by the trigger and I'll show you the operation of that end. There's our laser worn in hats Lester de Mille what? she'll be right. We've got ourselves a very simplistic interface here as well I hope it works. The E-series is a bit annoying.

Let's see how long it takes to boot up. There we go, it's ready to work, no problems at all. It does have an auto shutter on the thing I believe So there you go. we can see the image from the lepton sensor of course and that but that measurement spot in the center where it's taking that reading as I said not taking it from the lepton sensor, it's taking it from the from this window here and your traditional are pyroelectric infrared sensor so yet totally different.

It's a combination of the two so it's really just using the lepton sensor and that image just as a visual guide. and then if I press the button like this bingo we can see the dual spots and I'll show you those better in a minute. Now one thing I found instantly annoying about it is that you press the button down and your lasers come on as you'd expect, right to get your window of where it's actually measuring. But if you release the trigger, here we go.

If you release it, it pops up with an image of that and you can. Actually, you've got a couple of seconds to save that and it's just I find that just a little. Maybe a bit annoying, it would have been nice, but I don't know with a single trigger interface. Maybe you know what and dedicate one of the buttons on here to actually you know, save image or something like that rather than just have to trigger that, release it and then bang.

we can save that and then we can go back in here and go in here and we can go. There's our image. We've only got one, That's it. But yeah, I don't know.

It's a little bit annoying. Anyway, in terms of our menu interface, it is incredibly simplistic. We can change the color thing there. we have two choices for that so we can go out of there.

There we go. We've got the blue one or the coloured one via default and so nothing fancy there at all. We can set the emissivity, which is fantastic. We can set that in point nine, five fault, and it looks like we can have a totally custom value in there, which is terrific.

We can increment that to anything we want, so that's very nice. Got a couple of presets that works well and apart from that we can turn our laser off and on when we pull the trigger on the thing and Celsius and Fahrenheit for you Yanks we can turn off the centre spot, although if you do that, it still displays the temperature. We can set the time out and we can set the time and date which is used to stamp the files obviously. and well, that's it.

That's all she wrote. Version 1.5 Oh, and there's nothing else fancy at all in this thing is designed to be completely idiot proof and that's the advantage of this over like a full thermal camera like this. This is the huge advantage and it's more of a niche market because it's not a true thermal imaging camera. with all the bells and whistles of the E-series you want that or you get the E-series which is fantastic.

But for those who just want to go out and spot measure a temperature and you traditionally use one of these, well, this one is better. Yeah, it cost you a bit more coin, but it's nice to have the thermal image in there. So if you're going out measuring the temperature of your fuse box or your industrial machinery or something like that, instead of having to map, you know, using one of these, you have to move it over the whole thing to try and find the hot spot. This one just you know you can instantly and easily see the hot spot by virtue of the Lepton sensor and the thermal camera in there.

so it's worth every cent. But yet no MSX technology. but it's just designed to get a ballpark so that you can move the cursor over the hot spot you want to measure and then get it within light lighting up with the lasers and then you take your reading. So it's designed to do one job and one job only.

When I first got the specs for this thing I thought ah you know, look at it. It's quite expensive because it's not as good as the Fleur one in terms of having the MSX technology and the camera. but I can appreciate how you know you can't use the Fleur one with your iPhone in some industrial environment. you've got gloves on or you got whatever.

You know it's a pain in the ass. This thing does a beautiful job. SuperDuper rugged drop proof to 2 meters and simple to use. Turn it on and it just works.

So yeah, but if you want a thermal camera it's not for you, get one of these. Okay, what I've got is my HP power supply here and if you compare the thermal images of the two, there's just no contest and you wouldn't expect there to be either. I Mean this one has the 320 by 240 sensor with the MSX technology so it shows all of the detail and this one, well, just shows a few hotspots. but still, you know it's yeah.

I'm not using it correctly here. This is not its intended purpose, but I just wanted to show you the difference there. and if we turn off the MSX technology on the E8 there, you can see the difference in the quality of the you know, the 320 by 240 sensor in the E8 compared to that 80 by 60 Lepton sensor. Their huge difference.

But you know this thing's good enough for just its intended ballpark purpose. Are there's that auto power off? Yeah, but you can change that obviously. And of course, if you're trying to measure small details like that hot resistor down there, there's no contest. I Mean the the E8 is saying that is.

you know 70 to 74 seventy eighty degrees because it can get it can measure directly the individual pixel on that thermal sensor. But the TG 163 sorry I can't get the glare on the light. You know because you can see the laser spots there. It is the averaging over a bigger area like that.

You know it's not there. We go. It's no, it's not too bad, but you've got to muck around and get it because if average is over a larger area, you're not going to get fine detail measurements with this thing. But that's not what it's designed to do.

So I Really, you know, not using the thing within its intended use I just wanted to show you that and I just wanted to show you also how these laser spots change. You can see that they're almost vertical like that at that distance. In fact, I can bring them down and their vertical at that distance. and then they move like that as you get closer and the further away you get, the more they spin around like that.

But basically what it's telling you is that your measurements window is between those two dots. so it's basically a circle around those two dots there B in the outer limits. and if I shined on my door all the way over there. bingo, You can see that it's moved like that and if I walk towards it, here we go.

I will sorry, the sound will die I'm not wearing my wireless mic, but you'll see it rotate like that. There we go. So there you have it. That's a brief look at the flirty G 165 I Guess you could call it a visual thermometer.

that's the term that Fluke use for their VT O2 and VT O4. and I've tried the fluke VT O2 and it is awful. It really is I can if I can I've got some video footage of that I might try and include it here. I Got some old footage and yeah, it's truly awful.

So compared to that, this thing is absolutely fantastic. It's got a bigger industrial temperature range compared to the Fleur one for example which only has 0 to 100. This does - 25 - plus 380 and it really is easy to use. rugged.

I Haven't tried the 2 meter drop test yet, but yeah, it really is. Um, it does the business and super high quality as you'd expect from a floor, but possibly a bit pricey at $4.99 But it's not the consumer market that the Fleur one was trying to target. But if you need as I said, a real thermal camera, go for the E series much better. and I guess I Can kind of understand not having the MSX technology in there because it would really start to compete with this.

so they've deliberately tried to out lower the cost and keep it out there. but I would have preferred a cheaper camera there. I Think you know everything? Anyone looking for something like that? It's a bit pricey, but I guess you don't care for those companies who are you know need this capability. So yeah, it's a very nice bit of kit and this doesn't have any video capability like the Fleur one either.

so it's just you know. if you want video, you're going to go for the consumer Fleur one or the upmarket Eseries. Hi guys, just a quick impromptu video checking out the new fluke VT o two thermal camera and it doesn't look very good folks. Let's do some more practical tests comparing to the Fleur I three camera which was seen before.

So what we've got is a can filled with hot water there with that matte black on it. So its emissivity is going to be about not points at 95. Well, there abouts and it's only on one half and the emissivity on the other side is of course going to be pretty horrible. And let's check out.

look at the difference in that compared to the Fleur no contest whatsoever. the fluke VTO - is absolute garbage. Really is. It's um, it's like a blob.

Have not no idea what sort of sensor or lens they're using in that thing, but it's pretty awful look at that. Not impressed at all and the temperature does if you get it just right. It does seem to work, but does seem to be reasonably accurate in that respect. but otherwise it's just pretty garbage.

Can we turn the camera view on? There we go. So we've got the camera view and but yeah, it's just a fuzzy blob. Hopeless. Really no contest whatsoever.

And if we do some lights up on the roof here, there's just, ah, man, the fluke is just hopeless. Okay, switch it back to full look, that just a blob. So you go wonder what lens and sensor they're using in this thing and there's supposed to be a human in there somewhere and looks like just a blob on the fluke. Unbelievable.

So yes, folks, the Fluke VTO - looks like it's all marketing. it's really, it's performance is probably the worst I've ever seen in a thermal camera. It's just hopeless. I'm jeez.

I don't know One thing I don't like about it either is that the screen is on an angle like this and the sensor is on a different angle. So when you're actually pointing it at something, you've got a sort of, you know, sort of mentally offset the thing. whereas the Fleur you know the screen is, you can't really hard to see that the screen is parallel with the sensor so in use it's um, this thing's just really annoying to aim at things I don't like it at all. So anyway I just had a very quick play around with it.

but I think that's an absolute fail. So I thumbs down. Next up, one from stroller Yes, Charlie, mum's good. Eh Charlie? Um, it? what are poopy and Tigger awesome.

Let's have a look. make sure I don't cut my mat here. Goodness. a whole bunch of a whole bunch of stuff for Sagan Look at that whole bunch and we have a note.

Let's have a read. Well, this one's well worth reading. It's actually from Julie Charlie's mama. Charlie is a 13 year old of Viewer of the Eevblog and I actually uh, he contacted me a month or two back and I actually sent him a one of the Tektronix scopes that I had.

um because he didn't have one. So anyway, um Charlie I had no idea but Charlie was in really had some medical problems. um early on and he's done some fantastic stuff for the Westmead Children's Hospital as ambassador and in 2012 he completed his Commercial Radio School training. He wants to become a radio broadcaster.

Good on your Charlie. That's awesome and he's been on that 2 GB which is a local radio stationed here a couple of times. Fantastic! thank you very much. And here is a Charlie's story and I just wanted to show this.

look at this. This is terrific. Charlie celebrates two years since his life-saving liver transplant. Ah, I had no idea Charlie Fantastic there he is.

Look at that seven weeks old just diagnosed with Alpha One anti goodness. That doesn't sound good, but it sounds like he's doing pretty well these days. and Westmead Children's Hospital like safeties. ah, life with AM liver.

ah liver transplant. Terrific! I Believe you can go on and live a very normal life with it. when you have a liver transplant, please correct me if I'm wrong. but thank you very much Julie Charlie's mum for sending this stuff in for Sagan and Sagan Westmead Children's Hospital actually saved a little Sagan as well for those following long tweets at home about a year ago or something, he had a paint.

he got a peanut umm a nut stuck in his art lung Airways and yeah, they had a team of like seven surgeons operate on him and they removed it. no problems whatsoever. So massive! Thumbs up to West me. Children's Hospital One of the best hospitals in the world.

thank you very much Charlie and Julie as well I Hope you enjoy the scope and I hope you have an excellent career. good on your Charlie Two thumbs up! Speaking of medical wire issues like this, I Got some really good friends whose little boy has our congenital muscular dystrophy. oh, really, a massively debilitating disease problem and they've actually got a possible campaign coming up in two days time and I'll link to it. At the moment they've just got a Facebook page, but very shortly they'll have that.

It's called Beat for Life and they're trying to raise money for research into this and for drug art trials for it for congenital muscular dystrophy. So please, if you can help out throughout that research all the money goes into the research for that horrible disease, then please do so. The links will be down below Very much appreciated Is a good friend of little Sagan haha All the fun of sand without the mess sounds awesome. Thank you very much Guys say gonna love this dude I've just wanted to thank you for the kindness time in Oscilloscope you said Charley You're very kind.

We appreciate my random act of kindness which we chose week a brighter one. No worries, he really loves electronics. Had a keen interest way before school even started. That is the best way to go, as did the best electronics professionals.

I Know Can I offer any advice on post school education to get into the field? Well, jeez, how long have we got? Aha, he's already Charlie's already streets ahead of everyone else, having it for a hobby, having that interest and working on stuff outside of the the educational system given his age. Can't do our formal education yet, but you know once that age gets in that you can start formal education definitely. But already Streets head get involved in possibly public garden projects. just build design and build stuff.

And I've done videos on job interview, art, tips and things like that. The absolute best thing you can do is bring along stuff you've designed and worked on because that's what it's all about. There's already Streets ahead, so good on your Charlie! Next up, we have someone you've seen before. LPRs low-power radio solutions the Eric you know modules.

Um, they have sent something in there got having a second suck of the SAP and they've sent in some another wireless module. Oh yeah, there we go. Nice to see you again mate. Here are your Eric modules updated with the latest software? Yes! I've done a video on these before the Eric There we go.

That's Eric He's a yes, he's being mended because I broke him in a previous video and these little light low-power radio modules are very good and check them out. I'll link them in down below. I've talked about them in a previous video. They're quite neat and this is very typical of a these sort of modules.

You can see these like Half Moon Casta Lations Here they're called on their side of the board and this is an easy way just to either surface mount them on these types of modules onto your PCB or arm. You could actually you know use them standoffs or as we saw in the previous video on these things, you can actually get clips that actually connect in there and these are really easy to do on the board. You can see that you're just doing like as a regular through-hole pad and then just define your cut your routing path on your board to go straight through the center of the hole and then you end up with um yeah, my pointer looks really huge on here. You end up with this Halfmoon shape with the plate in.

go in through the Halfmoon hole there and it really is an easy and simple technique to do that. those ones on the side. they're a bit messy, these ones here a little bit cleaner but yet quite a common technique. Cast elations.

Next up, we have a huge one and it's been here for a while. Sorry Josh Parker he's from Orange in California Just Orange not Orange County or just Orange There you go. I'm in the US thank you very much. So let's crack this thing open.

And by the way, this mat was pretty tear resistant I Did actually dig into it and scratched it but didn't cut through. Fantastic! So let's let's crack into this and let's have a look. I Think we're gonna like what's in here I think I have an idea what's in here and it's not an Amazon item. but it does come in an Amazon box.

Let's get rid of that. so those foam pellets and No let's check it out. We have a note inside which I'll show you when I read in a minute. Ah goodness God open it again.

sorry. this could take a while bitter. Oh listen, what's a cruddy crap I don't know what? Don't know what that is anyway. yeah lots of crud, lots of crud.

Not happy. pull it in the lab. but tada, what we have is an amp X umm memory 16 K memory module. Let's take a look at it.

There we go, Huh? Can't see much our memory on the top there, but it is to board construction. Hmm, let's read the notes, see what we got here. Friendly greetings Dave And to you too, Included is a 16 K word ferrite core memory board made by Impacts sometime in the late 70s. Bought a pair of month eBay according to survey unused spares for the Nasa/esa Myrtle 125 Space Lab ground computers during the early parts of the Space Shuttle program.

Fantastic! Apparently it's an 18-bit memory configuration with 16-bit word plus one parity bit plus one protection bit which you work out over a quarter of a million ferrite cores. Goodness sake, where are they hidden? I Haven't been able to find much info, but it seems to have been on a fast, larger module of the more common Mitra 115 Ampex Mostly known for the magnetic storage products and haven't been able to find many details if its history too good to pass up. it just had to share one with you and other viewers. thank you very much.

and yes, left it sealed in the original packaging envy net since 1993. hence all the crust, it could be like Mouse poo or something like that Wow thank you very much Josh This is awesome and there's some links down below which I'll include and here we go: Mitra 125s okay for space Iowa This would have been in one of the journals back in the day and add in one the electronics or computer magazines I guess and there you go. Can't read that of course, but I think he sent me a um email copy of this I'll included if I can check it out. it's all very well.

I'm not going to say boring because it's in. It's still nice in its own right here, but we want to course see the ferrite core memory. Unfortunately, it looks like there I'm going to have to undo it all. It's a two board construction here and I can't see any ferrite core memory.

Obviously, it's in there. it's in the center here on the lower board and this is all the driver stuff which goes along with it all. dip technology. of course.

that's if we can get a date code on one of these 32nd week 1975. So there you go. There's some more more 74 date code stuff down here. And yeah, all that.

TI Parts Seven, Four, Forty Twos for example. And yeah, probably other stuff that we can get to get data on. But we've got a whole bunch of drivers and things along here and there's some interesting things to note. Actually, look at this inside here.

you'll see that look at those under there that run the whole length of these chips. These were very common back in the day. These are actually decoupling caps that run under the chips and then go down into the same holes as the chip. So you put the big decoupling cap on first and then you through the holes and then you put the there there.

Actually, they would be totally custom-made for the particular pitch between the chips in here and then inserted into the particular power pin holes you used to be able to get our generic ones. Maybe you still can that go into dip packages like this and they'll have you know. One pin over here and one pin over here for power and power and ground for example. But this would have been custom made and it's a bulk bulk decoupling cap for all of these chips here.

and likewise right on the edge of the board. Look at this. It is a bulk decoupling cap. You can see there, you see the pins down in here.

It's a bog decoupling cap that runs the entire length the board. Look at that. Absolutely fantastic. And then we got some horrible dip.

tan. Limbs here look color coded are beautiful. Those were the days. But and then they've got them running right up the length of these chips as well.

So it's um, if you have a look at that, there you go. they've got a running all over the shop. I Mean this thing would have only been working at a couple of megahertz I guess. but you know you've got to have some decoupling on there and that bulk decoupling is a way to do that on probably I Assume maybe a double-sided board and yep, it is a double-sided board.

I can actually see through that or if you hold it up to the light and just start regular tin plate on the bottom. There's no solder mask or no overlay or anything on the bottom side, so this is the board we need to screw out which will have the memory on it because there's nothing on the top here. We should be able to unscrew that pretty easily and it's a really fascinating board mix of technology of a resistor arrays. They've got their their resistor networks I'm assuming so yeah.

Interesting mix. You will notice the turrets the through it so they've got the pins sticking up, bit of corrosion on that bottom board, the pins sticking up and then into the turrets mounted on the top board. So that's how they join the two boards together and absolutely fascinating board. I Like this one.

Now tell you what. This really took some prizing apart. There's a lot of force that goes into that and tada. Aha, we're robbed.

We still can't see it. We've got some more drivers on here and see there's nothing on the bottom to store the tin plate and got some more drivers around here, but this is where the 16k core memory will be hidden. Ah, let's get this off. and for those playing along at home, there's the sticker.

It's the Model 1600 is zero number two thousand, six hundred and seventy three and it needs five volt and fifteen volt supplies so you can probably still power this thing up if we can even get schematics for it I Doubt it. And of course we've had some ferrite core memory on here before and I've shown that and it really is sexy old-school technology and now I Still need to get that one. They're off and well I Suspect the warranty is not valid anymore from the mid-70s so screw that warranty and let's get into it. Hey, we're in are in like Flynn Look at that.

look at the density on that. That is just incredible. I Can't zoom in enough? Aha! and if you thought my previous one was tiny, look, You can still just see the ferrite rings in there if you are viewing this in HD most likely. but compare that with this one and whole crap macro lens time.

Oh wow, look at that. That is stunning. Look at the density of those are the ferrite rings and he's absolutely incredible. Sorry I can't really can't get a huge amount better than that, but that is just Wow Unbelievable.

Look at all these ferrite rings. Each ferrite ring of course stores one bit of data in the magnetic field and a probably I don't know could still have data on it these days if we could figure out how to read the bastard out. So that is just utter madness that is incredible. Oh my goodness.

Sorry, my macro lens isn't good enough as you can see the distortion of the lens and the broquet around the outside. It just just isn't good enough to really capture this sort of detail. It's absolutely incredible. Check out: these are just massive buses.

This enamel-coated very fine enamel coated wire go into wired into individual pads like that which then go into these big dip chips. It's just ma just branch off like that as we go down. it just gets thinner, thinner, thinner until well as a few branching out like that like, oh, we couldn't fit that on the board so we're just branching these off down here. It's just insane.

Then you've just got the bundles of multicolored enamel coated wire doing the rows and columns and then in there and it's and of course the sense line in the inhibit line. It's just I don't even want to know how they manufacture this thing. Well actually I do because it'll be totally fascinating. but like it is rocket science.

there you go. I'm shooting that from near-vertical with my times 10 macro lens and almost the fool I think I am yet the full 20 times optical zoom on my Canon HfG 30 plus the times 10 macro lens and that is just ridiculous. What is the dimensions down in there? Let me get a ruler and I'm a little bit annoyed that I can't find my really fine graticule measurement microscope up marker. but here's a steel ruler with 1/2 millimeter increments there.

and well, there's at least two of those per half millimeter spacing. That's just crazy. So there's an attempt to measure it with my micro ruler there. and well, each little ferrite rings a bit.

roughly, just maybe just under half a millimeter diameter. Actually, they're not a huge amount smaller than the existing ferrite rings that I had on the previous one. I showed. It's just really, essentially just the density that they're able to.

You know, thread these things with I mean it's got to be at least 10 times the density in this thing compared to the old board. Just look at that. there's no comparison in the density of that. So you know, let's call it by almost the same size a ferrite ring.

Slightly smaller, but that that density. they overlap each other in the in the horizontal direction. They're crazy. But of course, you're not going to get any interaction between the ferrite cores because it's the wire actually running through it and the fact that it's a ferrite ring and the magnetics of how that works.

You don't actually get any interfere stooop from the ferrets next to it, so it works. a treat. So you can basically as long as you got the wires actually physically going through them, you can, pretty much, um, you know, pack them as dense as you want there. So thank you very much.

Josh for sending in that marvelous piece of spaceship Le Space Shuttle late 70s our vintage computer technology and we love ferrite core rope. memory like this is just fantastic. I Showed off my previous one at the electronics trade show and it was a huge hit. but like I had the tag on a microscope there and people really you know lusted after that.

That was double sided technology. by the way, this one didn't need it because of the incredible density in this thing. 16 K I Don't know if X 16 K bytes or 16 K bits. Hmm.

Anyway, thank you very much. This is just awesome. It's a feature piece for sure. Flammable you, you.
