Hi Welcome to everyone's favorite segment: Mailbag. Yes, I'm back in the old lab. And yes, as promised, I've got the backdrop. We're inside another lab.

Yeah, sure. Dave. Um, this one is Ian Johnston's lab. You might know the name Ian Johnston who's uh, sent stuff into the mailbag before, in particular the voltage reference standard.

So this is his lab where he actually uh, designs, builds and calibrates and I pre assembles I guess the voltage calibration standard. So it's Ian Johnston.com Link it in down below and check it out. So I don't know if this works that great yet. I can't see as much of the bench as I was hoping to see.

I guess I could work with the camera angles a bit. Cameras way back there, like three meters away or something just to get the angle required for bloody hit a bloody screensaver. Ah, I fixed that bastard. Anyway, let's take a look at the lab.

We've got a classic uh, Hp I guess agility on Keysight 3458 or 3458a, the classic uh, eight and a half digit multimeter. And if it's good enough as a transfer standing in Keysight's own calibration facility which I've done videos on by the way, um, then it's good. More than good enough as a transfer, uh, calibration standard in Ian Johnston's lab or anyone's lab for that matter. It is the classic device for uh, you know, transfer standard for calibrating multi.

I mean it's a multimeter, but people use it as a like a calibration reference standard so you can see some of the voltage references over here. I spy um the same and what looks like the same Stanford Research dual channel analog filter that I've got. done a repair video on that? not quite sure what that is. We've got an old Hp Uh multimeter up here.

What else we got? Uh is old school power supply. Ah, real analog meters when we know chicken dinner that looks like a frequency count? I can't quite. I don't have the resolution on here to read it. Got a couple of Keithley multimeters here.

Winner 34461a Keysight's new replacement for the 34401a. We've got electronic load down here. Um, these are interesting circuit specialist power supply. Check out the screw terminals on here.

None of that binding post rubbish. Good old-fashioned metal screw terminals. Love it. Anyway, our Keysight that looks like a 3000 series is it got to have a second scope.

So I've got a rye goal and what is that puppy that's oh that? That's a function Gen and those weird ass pommy plugs? Look at that Jbc iron down there. Absolutely fantastic. So there you go. Thank you very much Ian for sending in your lab photo.

If you want to see your lab I've got. I'm going to have one more today coming up later, so stick around. But if you want your lab in the background here then it's got to be. Send it to me As higher resolution as you can get, as well lit as you can get and shot at an angle that it kind of sort of appears like I'm actually in there.

And also, please make it 16 9 aspect ratio. otherwise I've got to crop it. which I did with this one. anyway.

details down below for that and tell me how you want to be credited and all that sort of jazz. Anyway, let's get to it. I do have a leftover one from last time, Lisa? Sorry. It's really lightweight.

Wow. There's nothing in it. Um, don Don Pablo I guess is a Bloody Queenslander from Australia affectionately of course. Um, yeah, that's what we call Queenslanders.

Bloody Queenslanders. Can't beat us at Bloody Footy though. Love having space in a lab. I can just throw stuff.

Beautiful. It's a lot of bubble wrap, which is great. I can always reuse bubble wrap when I'm packing and shipping stuff. Okay, it's taped up.

This must be really important. Let's look what we've got. What do we got? We've got Jbl Headphones Wireless. Jbl I get.

yeah, Bluetooth. Let's have a look. It may not be it. It could be something else in here.

Yeah, it's empty on top. Yep, no, there's nothing. There's literally nothing. uh.

one want? Don't have my buttons here. I haven't brought them over yet. Um, it's like, um. it's empty.

It's the first time I've received a box. It's quite a nice box. When you talk about the box, look at this. It's you know.

um, this multi-layer thing that's got integrated, uh, cardboard? You know, corrugated. Um, well, not corrugated. But two things up there that hold that in place. Got a little tray? It's got the requisite stuff that's a decent design box.

Actually don't mind that. But um, yeah, I don't get it, huh? So yeah. Bloody Queenslanders indeed. And I guess that's funny.

Send in an empty box. Okay, Um, yeah. Anyway, another another one from Australia and Bloody Ripper. Uh.

Jayden Cars Lake. thank you very much. From Belmont in Western Australia, Australia Hi to all my Western Australian viewers. So let's give this a bowl.

Let's see what Jaden sent in That wasn't a note? Was it? No. don't think so. Anyway, let's have a look more audience. Geez, we've got a theme.

Um, these are. um, they're bluetooth. Um. earbud things.

Not a fan of earbuds? Not a fan at all. So these are, um, yeah. these newfangled things you see these hipsters wearing with the i don't know? Well, looks like I've got a bunch of miscellaneous stuff or miscellaneous bits. I guess we'll find out why in a minute.

Uh, it's taken something apart. Here we go. Alright, so it looks like it's pre-torn down. Ah, it's one of these googly um things.

and not not the Google one. But bloody speakers look alright. Separate like that. Otherwise, they go up like that.

So yeah, it's something is already pre-torn down. It's one of these, uh, you know. yeah. Speaker: No.

yeah, that is a Google. um, a Google thing. Um, yeah, I've got one of those. I was going to tear it down.

They sent it to me. Google sent it to me for free. They sent me an email saying, do you want one of these things for free because you're a Youtuber or something. I said, no, yeah, whatever.

I might be able to. I'm not going to plug it in and I might be able to use it for something. Um, a long time fan. A bunch of stuff torn apart, but nothing to do with them.

That's such a impulsive one of you. Hopefully you make something to do with them. Uh, there are five speakers, two bows, one Google Home mini that's what I was thinking of, and two generic Shenzhen market specials. There's also a remains of a Google home, and a set of cheap wireless earbuds that do barely work.

Yeah, okay. Sound Republic. Um, yeah. what are they? You know, Five bucks delivered on Aliexpress.

And yes, these are all the parts that actually came in it. And Jaden's plug in his um, Freelance It Support um skills as well As he said, if I sent in a resume anyway. Um, yeah. all right, we'll take a quick squeeze.

Oh, he's ripped the cans to rip the cans off. So this is inside one of these Google Nest mini things and never use when I don't plug one of these bloody or seen or well, all hearing uh, devices into your network. like really, do you need to go? hey, Google Google me something. I mean, give me a break.

Anyway, Um there. Um, I assume that they're lead pipes. Light pipes going from the leads on the yep, they're there. Yep, leads on the back of the board so that sits in the top.

There somewhere. We've got four leads. They shine through the front I guess. Um, you know you don't want them to be too bright.

so that's uh, that's pretty good. So you've got your electronic-y doodads and then you've got your, well, your speaker. I thought the speaker came out the top. Oh right.

Yeah, I thought the speaker would be in the top like that, but it's it's not. Um, it's all. looks like it all comes out the sides around there. There you go.

that's interesting. So yep. brought in the top looks like a dessert I assume. does that go down like that? Yeah, it's got it.

yet. it would go in like that. Of course you wouldn't normally have that poking up into your cone there that just looks like a pretty ordinary how you're doing speaker and um, and the back case goes on. Ah, but hang on.

we won't have what looks like that looks like magnesium alloy. Oh, you could scrape some of that off and burn it if you wanted to to see if it is. But uh. nice little spike there.

Um, how does that? How does that go? Does that? That's the go. There you go. So oh, it sits in the spike. It's some acoustic spike thing There you go, which is supposed to disperse the sound evenly all the way around or your vent holes around there.

There you go. I guess that'd work all right. So at least they've put some thought into that, haven't they? So that's recently well constructed that's inside the nest. Mini.

uh, until we care about the chips. I mean, you know, really. We all know it's got permanent spyware in there anyway. So meh.

whatever. I'm not. For once, I don't really care about what's uh, inside the electronics on this thing. I'm just more interested in to see the construction really.

But yeah, uh. hands up in the comments down below. If you use one of these bloody stupid things, probably the same people who have like smart light bulbs and control them from this stupid shoe phone and, well, this is a speaker fest. Two generic or Shenzhen Ma or these the Shenzhen Market specials that looks like just a generic, uh, mylar dome in there.

Hey, there we go. Crack it. Yeah, yeah, just the Mylar dome jobby. Nothing special.

and uh-huh. They're the two Bose ones through your Bose fanboys made in Mexico. Hi to all my Mexican viewers. I'm not sure how many Mexican viewers I have, but you know, geez.

look at that is like Sue that is ridiculously deep. That is super deep. Look at that. you know the the throw on that is amazing for the size.

What is that? Like barely an inch across and like it's just enormous throw. Unbelievable. Speaker technology is actually coming. Yeah, a long way.

Especially like you know to get like a speaker that actually sounds half decent in a mobile phone is just like insane. Like you couldn't imagine. Uh, that technology 30 years ago? It was just nuts. Well, they don't like each other and these stupid earpod things.

I don't know. Why do you want another thing that you got to charge? You know, use a bloody cable for goodness sake I know. Like you know, the stupid new iphones don't even have uh, headphone ports anymore. Well that just popped off.

Um, there's your little pissant speaker and there's your little lithium ion or lithium polymer. Sorry about. oh puffy puffy ass. look at that.

Did it ever look like that? Or is that is that gone puffy? Oh geez. So the batteries in behind the speaker there and their board has just tucked tucked away down in there. So I guess that end pops off. There we go.

That's the way to do it. we don't care about. ah oh yeah. there we go.

Can we, ah, pull it? There we go. Got it. Ah beauty. Look at that.

there's our antenna and there it is. Can we read that chip on there? I don't think I'll bother to get data on and sorry. I just realized that I had my microphone pointing forwards instead of pointing behind the camera. Oops.

Um, so the audio up until now has probably been crap. so sorry about that. Anyway, there you go. Um, is is that a little? Is that a little microphone? Do these things have microphones? I don't know.

I don't use these stupid earpod things and nothing on the other side. Ah, there you go. So thank you very much Jaden for sending in all those bits and or bob audio devices. I was going to tear down my Google home Mini.

Now I don't have to. Um, there you go. Fascinating. Thanks mate.

Oh, you know I get excited about flat printed dead tree material. Um, Fantastic. Thank you very much Wayne Clay. Hold on! Hi to all my viewers in the old dart.

It just says sales brochure. So oh fantastic. I better open this one carefully. No, no, it's nothing at the top.

I think I can just do that. That was careful. I know what I'm doing. Professional.

That's all right. From Australia, What do we got? What is it? I don't know. It's well protected. Thank you.

Oh oh oh wow. It's the Sinclair C fight. See, I can't hold stuff up to the, um, the camera anymore. That's really annoying.

The Sinclair. It's just because I need the angle for the screen. Oh, that's a downside to this anyway. Um, Sinclair C5 Brochure.

Oh look, it's got the original Priority Free post reply envelope in it. Oh the Ah, thank you very much. This is awesome. I was thinking.

with a couple of week months left on my two and a half months now left on my old lab, my old lab has room to do a Sinclair C5 teardown and retrofit. I can do it in the bunker, but you know it's just nicer in the lab. I've got new lighting in the bunker, by the way. So oh, look at the oh, look at this.

I exploded. Oh, I'll show you. Oh, the motor. Oh, it's pornographic.

Get me demonetised. Oh, and it's the original letter signed by Sir Clive himself. Well, I don't know if it's like actually individually signed by Circlive, but it's in a different color. It's got to be legit.

Um, at last, the Sync Air Electric vehicle and you have priority. Please finally close the Sinclair C5 sales brochure circle at circa 1985. I knew I had one in my life send it off for off for it whilst down while he was at school. Absolutely fantastic.

Finally looked at it whilst being on lockdown. Awesome! Thank you very much Wayne. Let's have a squeeze at the Sinclair C5 brochure and check this out. Sir Clive Sinclair.

The Sinclair C5 doesn't it look so fantastic? I I own one and well, you know it doesn't look as Schmick in real life, but sure, my ones are, you know, quite old. But yeah, don't they make it look absolutely fantastic in the brochures. They really wow. So futuristic Look at that.

It was the future of Sir Clive Sinclair's future of trans personal transportation. And yeah, everyone said they were so low profile to the ground. Everyone started getting run over in them. so they had to add the big uh optional flag pole at the back.

So if you valued your life, you bought the you bought the flagpole. Oh yes, and no road license. No road tax. Even 14 year olds can use it.

Fantastic. And you put your groceries in the back? Look at that. Trust me. There's not much room there really.

But uh, yeah, doesn't it? The brochure really sells this thing. Battery rechargeable. Battery takes you up to 20 miles for less than 5p. That's pence for you.

Uh, yanks who probably don't understand foreign currency anyway? Um, yeah. doesn't look sophisticated in his suit driving, you know, And a whole fleet of look in one car parking spot. You can fit five Sinclair C5s and classic 80s hairdos. Ah, terrific.

Go to your sport. You know your kids can drive it to their Uh sports field for their soccer practice or whatever. And ah, terrific, lifelong, long life running tests. There you go.

There's some of the Uh test jigs that they had. the chassis strength test rig. Wow. Some of the test rigs they use, that's that's fascinating.

There you go, wonder if anyone still has any of those. Wow. Look at that simulated load testing. Wow.

So that would actually press down on it. And to simulate, you know, big fatties right in this thing And like, over so you can. That's wow. Gone to a bit of effort there to simulate all that.

There you go. There's an exploded view, but of course it doesn't look as sophisticated when you realize it's got pedals inside. I wouldn't be showing that, so it looks a little bit more toy like there. I wouldn't have shown that all.

but look at the motor. Oh, it looks fantastic. That cutaway view just. oh, that really sells it.

Nice. so powerful and sophisticated electric motor in this thing. Um, and yeah, it's it's pretty pissed week when you actually drive the thing. But anyway.

um. deep discharge battery included. 19-foot turning circle. There you go.

Sophisticated lead bar graph display which used, uh, a Gatorade, uh logic chip I believe to actually do that, you know, pretty advanced. uh. Sinclair back in the day. but uh.

and the optional rain, the rain jacket, and the rain cover. That's wow. So glamorous. And the technical specifications? Oh, how to order order? would you like to order one? Uh yeah.

428 pounds? There it is back in the day. Wow. You could just fill out your order form, you know. Um, the please debit.

There You go. You please debit my Barclay card, my trust card, my access card. Now this Visa or Mastercard rubbish back then. And there's the letter from Sir Clive himself.

Oh, there wasn't Sir back then. Uh, now he is. Uh, there you go. After that January 1985 Sinclair Vehicles Limited.

How many did they sell in the end? And yeah, nobody's used them these days. They're just a novelty item, but oh well, it was. You know, a decent idea at the time I guess, but didn't take off anyway. Thank you very much Wayne for sending that in.

Brilliant! Yes, I'm in a new lab. Thank you very much Eunice Kerbin. And hi to all my Turkish viewers. Yes, we're in a Turkish lab.

Fantastic! And Eunice Uh is from Ek Geophysical Solutions. I guess that's his company and I'll link it in down below. Thank you very much. So this is his home lab.

Check it out. Absolutely brilliant. Hang on for a minute. there.

I thought this up here was an old-school eprom eraser. but I don't think it is because I see like a chart in there as if it's like got some temperature profile thing. but it's got a pull-out tray like that. It looks too fancy pantsy for a Uv eprom eraser.

Anyway, that's kind of like old school what they look like back into what the fancy panty ones did. Anyway, looks like we've got an O1 scope here. We've got a Rye Gold function Gen. We've got uh, is that like an 01 Power? Whose power supply is that I can't remember? We've got a Bk Precision Beta kit, rye gold, uh, bench meter, couple of Rhigo power supplies geez, Rygall spectrum analyzer.

We've got an old-school uh frequency counter there, but looks of it, it's looking at the Eev log beauty. Ah, we're not sure where it's going. That's an external monitor for the another Rygal scope here, so no shortage of scopes in. There's another O1 scope down the bottom.

Got a microscope here? That's that little jobbie down there. We've got a fancy panty fluke meter, and I'm curious about these coils anyway. So these are some sort of, uh, geophysical thing anyway. if you don't know.

I spent at least a decade in the geophysical industry, although the underwater sonar, uh, geophysical industry. Anyway, it was geophysics, but it was underwater instead of land gear physics. So then that looks like a homemade, uh, like Malta Six channel, uh, power supply up there. And this bit of kit up here.

This is interesting. This is some sort of custom job. I can't read out exactly what that is, but it's got a numeric keypad and a couple of Lcds. Maybe it's just like a custom bit of test gear or something like that.

Perhaps so. Old school analog scope up there. Nice soldering station over here, although the microscope's over here, but the soldering gears over here, reminds me of my own lab. Like everything's just moving everything everywhere constantly.

Hopefully when I set up this lab again, I'll have dedicated stations. That's the plan. anyway. Anyway, very cool lab.

This is quite decently set up. I like it. Hi to all my New Zealand viewers and from Palmerston North. thank you very much T.

Noyce. so let's have a squeeze What's in here? This is kind of tapes all over the place. Okay, what do we got? We've got a note and oh this is interesting. Wow.

Okay, handspring. Don't know what that is, but that's an I look at that that is an Ibm bank. uh card magnetic stripe card reader. like you know, I sure have seen that exact model in the banks they've um you know.

usually they got them like integrated into like the keyboards. often these days and stuff like that used to you. I used to work at Keycorp back in the day. I can't remember if we had them integrated into the oh geez, it was too long.

It was like 94. Something like that. Anyway, Um, the key court made F Posta terminals, a visor, Pda? I don't I have never seen a visor brand, never seen nor heard it. You know it looks like a little palm three.

kind of. uh, thing. I used to use a part three. there's the reader for it.

So cool. A couple interesting tear downs. Todd's an avionics technician in the New Zealand Defense Force Beauty. He's having a clear out and reducing his horn of scavenged components.

Scavenge parts are less necessary than ever. in an age of online ordering in onesies and twosies, unfortunately, he's right. it's just too cheap, easy and simple to order. You know you've got to have like kits of all your you know, through hole resistors, your surface mount resistors, your surface mount caps, and just a few you know, jelly bean parts and stuff like that.

But beyond that, yeah, salvaging stuff. As much as I hate to say it, he's probably right. Anyway, a weather station transmitter. Oh okay, so this was it came from Bank.

Doesn't say which one he used back in the 80s ever been. He's been planning to reverse engineer it for over 25 years. However, it hasn't happened in 25 years, so it's probably never going to happen. I've still got stuff from 25 years ago that yeah, I know exactly what you're talking about and would be quicker and easier to order a Usb one from Aliexpress.

Yes, it would, unfortunately. Handspring visor. I know you like Palm Os, so here is another one. I found this in bargain bin.

The Tricky Dicks. Oh there you go my his first Usb device. His novel feature is the expansion port on the back. Oh, there is an expansion header down in there.

Wow, that's that's huge. What is that? A 80 way expansion header? That's interesting now. Wow, isn't this. Trust me.

This is all metal, no plastic rubbish. Uh, that's bril built like a brick. Dunny. Unbelievable.

Let's ah, ah, there you go. Made in the United States of America for Ibm? huh? So who actually did Ibm manufactured? or was it just subcontractor manufacturing in the Usa for Ibm? Armonk? All right, let's see what we've got in here. Ah, there we go. Beautiful.

Uh, 80 49? Yep. No surprises. Nice hand taped layout there. Beautiful.

Got all the curvy traces. None of that 45 degree rubbish. 1987 date code though. so you know, late 80s.

So we've got our first customer Ibm part number. I'm surprised we don't see more custom Ibm part numbers. Uh, that's interesting. but uh.

anyway. um yeah. basically what's that one? Um, everything else in here is, uh, digital. So yeah, they're just I getting the ones and the zeros out.

so I assume based on the analogy goodness around it here. All these tag tents. ooh evil tag tents. You have to wear the garlic around the neck to ward them off.

Uh. anyway. Oh, a link going directly over bodge wire. It's all happening here.

A very standard fare for the 80s. Um, even in Ibm gear. Yeah, so I presume that's the analog head. Uh, would be going into that.

and I did. the you know why they need the digital stuff to do things. I don't know when you know you've got a micro in there, you probably could have just fed it straight in and decoded it. I don't know.

So a fair bit of discrete wiring in here. Not sure what that is down in there or that some sort of uh, is that like a no. It's just grounded, shorter, two terminals shorted together. It's just A.

it's just a grounding point. Almost really. Um, interesting. Well, hello sailor, look at this.

I mean, it's going to be simple. There's just a read head and that's basically it. But check out this uh, leaf spring thing here. which just keeps nice even pressure on the card as it swipes through.

like if I lift up that oh, it does tilt a little bit, but isn't that nice? Wow. so yeah, isn't that groovy? I I really like that. Uh, that implementation is fantastic. Let me know if you've seen that anywhere else.

Anyone who's done tear downs, but yeah, I just that's that's great. It looks like yeah, it's a great way to keep nice, even firm pressure on the card as it uh, travels through. So there you go and they've got a little divot in there to match the uh read head. Nice.

Well done Ibm. This is an Ercus Instruments weather station receiver. Okay, um, let's crack it open. They're obviously connecting up to the sensors and whatnot from the uh using um, Rj11s there.

Oh, we've been blobbed. There you go. Look at that um chip on board, and then they've blobbed it. Um, that's interesting.

Usually you don't uh, see that sort of, uh, well, effort in quote marks by, you know, in something you know, reasonably low Vol. this would not be a high volume thing, would it? Or is that you know one of those consumer, uh, weather stations here they might have made. I don't know, tens of thousands of them or something like that. But uh, you can clearly see that's our antenna.

Oh, and Ferrite rod? Wow. Look at that. That's interesting. Uh, why are they? And so is that a cap? Is that a cap buried down in there? Yep, it sure is.

There you go. So they've got a tuned, um, a ferrite coil there. plus what looks like the 433 Meg transmitter. Oh no.

this is all in one. Because there's the sensor that's a, uh, that's got to be like a moisture. Um, you know, a humidity temperature sensor or whatever. So that's the sensor board.

and this is. They've got some tiny little coils down on the board there. Check that out. There you go.

itty-bitty They've just squeezed those apart. If they gunk that as well, just put a bit of gunk in there to separate that. So somebody would have, uh, hand tuned that on the production. uh, test jig.

And then they've got the antenna. and then that goes too. And then they've just got a tuned cap going down. So so yeah, that's interesting.

That's all she wrote. It's like an all-in-one thing. So this would be going to like external, uh, weather vein or you know, something like that. Um, you know to measure the wind speed and maybe a rain.

You know, an outdoor rain gauge or something like that as well. So just a sensor interface and you know it'd just be running a micro in there. You know, maybe an 805 one or something like that? Um, yeah. interesting.

And of course it wouldn't be mailbag without one from the United States of America. Thank you very much Manning Anyway, from San Diego. Like saying I've been to San Diego? Uh, that was interesting. And oh, the Sbo256al2 Voice synthesizer.

Chip Archer Um, you know that was Archer was the Radio Shack brand. Oh, absolutely fantastic voice synthesizer. I see, I can't can't find. I got in the mailbag like quite a while back.

was, um, what chip was it? No, it wasn't an Sbo256. Anyway, somebody sent one and I was looking for it and I can't find it Anyway, thank you. Got another one brand new. Ah, new in box.

Unbelievable. Thank you very much. Got an envelope and more loot inside. Oh yes, yes yes yes.

I used to use these. These are the direct etch dry transfers for making your own Pcbs. This is how we made Pcbs back in the old days. I'll show you a close-up of that because I can't get near the camera.

Damn it. Good thing about having the camera like three meters back. everything's in focus because I shoot with a constant aperture of like F7 or something like that to get greater depth of field. Anyway, and is this a fair dinkum letter? Yes, it is with something else in here.

Instructions for the series: Musical Board: Brian Menin, thank you very much. Oh yes, and he says yes in case the last one I received in the mail bag was probably croak. I've actually, um, yeah, I it's somewhere in the lab. I'll eventually find it.

but oh, new in box. Fantastic. So yes, Brian used to use the direct etch, um, transfers as well. You would stick them down.

You'd have all the different pads, all the different footprints. you'd stick them down on the board. Absolutely fantastic. And we have a circuit board demo.

Oh, and this is interesting. This is a demo board from Beckman who used to make multimeters and apparently Beckman in the 80s. They had a multimeter that sounded a tone when you were checking the resistance of the component and the tone varied. So this is something that you could use to like a little demo.

you could use in your in your resistance mode to play music with your thing. Um, that's that's kind of cool. Anyway, yeah, the pitch of the tone would change depending on how much resistance the component had is. Uh yeah, wow, that's very cool.

Um, unfortunately, I don't think I have any multimeter that'll do a variable pitch when you do the Ohms or continuity. Oh oh, Brian is Spicy Jack on the Eev blogs forum? Cool. There you go. The Beckman Hd 150 series Musical Band.

Fantastic. Obviously, I don't have a multimeter that can, uh, do this, but obviously it's designed to look 1.6 Ohms and then you know a couple of rungs up will be 2.4 and then it'll just get higher and higher. And if you've got a multimeter that, uh, changes pitch based on your continuity or your resistance value, then uh yeah, you can get you know, sweep along and and a bugle. what? Well, there you go.

20k, 35, 43. Got some high resistance carbon on there, that's for sure. And there you go, so you'd be able to play different notes I guess. And yep, direct, etch dry transfers.

This is how you laid out Pcbs. This is how I laid out Pcbs when I was a kid. You got all these different patterns you can buy it at your local Tandy store none of that Radio Shack rubbish here in Australia. and you had all your different footprints standard 0.1 inch dip and you had 0.1 inch dip with traces between so that you could get individual traces between pads.

That was, ah, that was mind-blowing Uh round. uh, metal can packages, your To92 packages and you even got bends and stuff like that But you could like bend around with your tapes and made in Holland. Oh my, my viewers from Ireland they don't call it Holland anymore, do they? But of course. uh, you needed like more traces than what you got on here.

These were just like big power strips or something like that. Really, You would, uh, get them on the Uh rolls. and of course the classic ones are Bishop graphics. Of course they were the Rolls-royce ones, but the old Rat Shack ones.

They'd do the trick. So of course they just had an adhesive backing on them and you would just, uh, peel them off, stick them directly onto your copper clad board. You did, you know, clean it first, give it a good old polish up and a shine, and then uh, you'd just place these directly on top and then you go over with a sheet, just pressing them all down. Uh, you know, making sure they're all firmly stuck down and then you just chuck it straight in the engine.

and of course, um, you'd be left with your traces and then you just like rub or rinse all this off. I forget how I got them off, did we rub them off? We just just just rinse them and they or put them in some solution and they uh, dissolved off the glue. I think I just rubbed them off with some steel wool or something. There you go.

It even came with instructions. Fantastic. Firmly polish the transfer patterns with the backing paper. emerge.

Pc board. shouldn't that be immersed? Pc board in ferrochloride? It's ferric chloride. Wait approximately 20 minutes for etching, clean away the transfer patterns from board with solvent. Um, yeah, no.

I think I just used a steel wool. oh mint in box. I don't want to take it out, but I will. Oh geez, was it really 13 bucks back in the day? Um, yeah.

I bought one of these back in the day as well as the uh not. this is the Uh speed this actual voice synthesizer. But they also had an Ascii 2 uh allophone conversion chip. uh, a matching one for this.

Which you know it made it simpler to just simply send in an Ascii string to it and then to convert it to the required alifunds. And it was okay. It was fun and of course you would get the data sheets in it. Absolutely brilliant.

So yeah, that that is a separate video that's that has been on the to-do list for a while. Awesome because I've already done a video on the Uh Archer voice recognition chip. I have to link that one in if I can remember it. Anyway, just search Eevee blog voice recognition or something.

So thanks Brian aka Spicy Jack on the Eev blog forum. If you're not on the Ev blog forum, what the hell are you doing? Thank you very much Richard Hensel from Mansfield. Uh oh H. Is that Ohio? I think so.

Anyway, old school letter. let's have a squiz. what's in it? Like tiny little envelope. It's always intriguing.

What do you get? Like is there like a Usually people just send a post it off. Five bucks. Thank you very much Donation Muffin Money Dave! I found this five dollar bill the other day and it won't do me much good. Please put this to good use for your channel.

Keep up the great content Richard, Thank you very much. He just found five bucks somewhere in Yankee land. Beauty. Thanks mate.

Although that is the uh, deprecated one. that's the old, the old school one with the old school queenie on it. Um, but I still spend direct from the People's Republic of China People's Republic. Okay, sure Jan.

Anyway, let's have a look. I know what this one is. Um, and they just raised a they just had a successful kickstarter for it. It's an updated suck of the Sav.

So there you go it is. the crow pie upside down. All the electrons are going to fall out. the that's up.

That's upside down. That's up the right way. Yeah, somebody put it in the wrong way. Anyway, well if you flip it I get you know if you flipped it like that it's it'll work.

So I don't know w which way would you design it? I don't know. I oh yeah, I wouldn't have designed it that way. I would rather flip something like that and expect to read it. rather than flip it like that and expect to read it.

Let us know in the comments down below which one. If I'm right, that's that's my preference is to flip it like that and read rather than over. Anyway, ages 8 plus this is going to be fantastic for Sagan. Uh, who's nine now? by the way.

Um, so that's a Crow Pie Two. So they raised like 650 000. I'll link to their store down below so you can just buy it. Now it's just it's done.

I think I assume they're shipping. I think I'll unbox this on the main camera back at the bench. And who better to open the Crow Pie 2 kit than Sagan because it says ages 8 plus and how old are you? Sagan 9 9? All right, let's open it up. Check it out.

What's it got? Um, I think it says Python Scratch, Arduino, Arduino, Micro Bit, Raspberry Pi Learning Minecraft Yay! Games and Ai Artificial Intelligence so you know you can program in scratch and Python as well. And uh, of course you program Minecraft too, don't you? Yeah, yeah, all right. let's open it up. This looks really good, doesn't it? It's better than the old one.

Yeah, by the looks of it, let's try and open it up. Um, middle over there. give it a little shimmy shimmy Yay! No, it's all black. Get there's the foam.

Ta-dah Oh yeah, I know this. and these are the. These are like vulnerable 3d minecraft locks. They scan and you scan.

and then they and then they load into your inventory. Yeah, so they've got little Rfid chips in them so that you can scan them. Tnt? All right. What do we get? Inside looks like we got two game controllers.

Yep, um oh, that's a Us plug. we'll have to fix that. Looks like some wise components. A bunch of components to stick into the breadboard.

Yeah, uh oh um. Power adapter? Yep. looks like not not really sure what that is. actually that looks like a remote control.

Plus, maybe. uh uh, no idea what that is. There's something in here. Nice little mouse.

cool little bluetooth wireless mouse motor. Some little yeah, oh, that's that's a servo motor. Yep. so the normal motor and a servo motor that's a stepper motor.

Yeah. So three different types of motors. They're the Rfid tags. Oh yep.

Tags for the minecraft blocks. Yep. So they go inside there so that you can scan them. Yeah, oh I think those like you detect moisture in the soil.

Mate, you are spot on. That is a moisture detector connections. Yeah, well done. Um, we've got the manual.

Excellent. And of course the most important component. All right. The raspberry pi itself.

Yeah, this is a crow pie. Two actually I think it says oh, this is weird. Oh, there we go. This is easy to unwrap.

now. how does this compare to the form factor of the old one? Oh well. It looks cooler and newer and looks like a laptop, doesn't it? Wow. Look at that.

It actually looks like a real. It opens up like a real light. Peel it off. Pretty satisfying.

Wow, look at that. That actually that looks fantastic. It just okay. let's have a look at the ports on that.

Oh, there's some on the other side. What type of ports that we have? We got there. I think we've got Usb ports. there.

Usb ports? Yeah, what else. Um, oh. Internet port. That's it.

That's it. Okay, there's more. There's more. I think we got a headphone port.

Yeah, another smaller Usb port, an on button, and looks like a Dc 12 Volt battery port or something jack. Yeah, for external power supply. All right. Wait, there's more.

All right. Ready for the round reveal. Let's go. So that would be a wireless bluetooth keyboard? Yeah, Yep.

yeah. you don't need to connect that. Wait, is that got a charge? It must have a charging port or something on it. Yep, there we go.

Okay, what we got Looks like a Rgb display. Yeah, Rgb Matrix display? Yeah. color. Oh, looks like we've got a, um, sorry about the lighting in here.

It's pretty poor actually. If you want to sit down, say yeah. Yeah, There we go. We'll get more lighting.

I'm going to peel this off. Yep. Little screen. Maybe for displaying text or something? It is.

It is. a. uh. text.

It's a alphanumeric character display for text. Yeah, um. We've got a breadboard, which we can obviously plug in the components that we found over here. Yeah, whole bunch of components.

Yeah, uh. looks like we've got a touch button. and it's a joystick. I think you can wiggle it.

Yeah, Joystick it is. Does it press in the middle too? No, No. uh. that's a motion sensor microphone.

Yeah. Keypad Matrix: Oh, that's a bit spongy. There's no tactile feedback in that. there's a bit of bit Spongebob Squarepants.

Yeah, Ah, we got a touch sensor. Yep. Vibrations say our buzzer step motor. That's the way you plug that in.

Um. screen. Driver Switch: Oh, Switch A to B: Uh, that's a light sensor. We got a light sensor.

Yeah, that's the Rfid tags. Oh yeah, those ones. And the sensor is next to it. You see the coil? You see the coil etched into the board.

Yeah, it's got a coil etched in. Yeah, that's cool. It's got some seven segment displays as well. So another sensor there.

There's a tilt sensor that's a bit annoying. Look at that. It doesn't sit flat. The screen.

You got to put the yeah, you got to put the screen. I just realized it's a face. Two eyes, a nose and a mouth. Look.

Two eyes are nose and a mouth. I think they're just the screw holes. but it does kind of look like that. Doesn't it? It does.

You're right. That's cool. All right. You want to power it on.

Sagan, Let's hope this works. Wait wait yeah. Look. we've got some leads down here.

Switched on Electro. That's the company that made it. Yep. Leds.

No single pound power saving. It just went into power saving mode. Seriously. Press it again.

Okay, just once. Hey, let's hear her on. Hmm. what's going on? Shouldn't take that long to boot.

A raspberry pi? ever? hold it? Yeah. hold it down. Wow. Nothing.

Oh sad look from Sagan. Oh oh sad. Lighting in here is terrible. Sorry.

we just got a single light source behind him. That's it. Okay, it's off. now.

try it again. Oh oh. that turned. yep.

Maybe hold it down. Yep, and let it go. Okay, it's latched on Electro. What does that say? Um, yes.

Oh, should I put this back on? Yeah. Okay, Yes. Ah, we're in. Where's our? Oh, we could have used the trackpad.

of course. Silly. All right. So look from Projects Minecraft, Ai Python.

The first thing I got is the Minecrafts. Although you are an expert scratch program, are you not an expert? But oh Python, when are you going to do your scratch tutorial? You're going to do a scratch tutorial video, aren't you? Oh yes, I was. Yes. All right.

So yeah, how much cooler is this than the other one? White cooler. Way cooler. Why is that? Well, because number one, it looks awesome. And number two, because in the old one, it didn't have some of the components under here that this one has here.

Yeah, the old one didn't have that. It didn't have that. Um, they didn't have a joystick. Oh yay, I'm used to it.

Yeah, there you go. straight into scratch. Oh, that's better. And what about the screen on it? Oh yeah.

Way bigger the old one used to be. Yeah, a little tiny. Top one, wasn't it? The blocks are tiny. I can make a game for you right now.

I don't think we've got time for the mailbag video, but maybe we can do a second channel video. Yeah, you're doing some scratch programming. Yeah, All right. maybe some Python too.

All right. So I'm still. You know. Kind of wobbly, wobbly on the pipe.

Still wobbly on Python? Yeah, no worries. Oh, by the way, it's Python. not Python. Really? Yeah, I call it Python.

It's a Pi fin. Okay, Python. Alright, so that's the unboxing of the Crow Pie 2. Well, yeah, I'm sure it all works.

a treat and interfaces. I think we did a demo last time, but we will just leave this to the unboxing. If you want to see the second channel. Leave comments down below.

and how do you rate that out of 10? Say again. the Crow Pie 2 9. 9 out of 10. Oh, it's good.

Java? Yeah, it does it. Yeah, look. Blue Jay Java. Oh, I don't know what Blue Jay Java is, but there you go: Calculator, Image viewer Yeah.

Libreoffice. Yup. Vlc media player, Python games, Libreoffice, All the and the Arduino Ide yeah, Minecraft. so that's pretty awesome.

Sega. You can just fold that up and it's all in there, isn't it? I know, like a laptop and you've got all your stuff making your wires. Could you? Is there any space under the keyboard between the keyboard and the rest of it? Or maybe there's a little bit of space for some wires. Yeah, you can shove some wires in there and them flatten them.

Yeah, that's right. that's terrific. I love this. You love it.

So how much fun are you going to have with that? Sagan? Out of what out of 10? Yep, Okay, um. a billion out of ten billion out of ten fun with the Crow Pie. Two. So Ultimate Verdict: Thumbs up or thumbs down.

Ah, two thumbs up. Cool. Thanks Sagan. And what do we say at the end of the videos? Catch you next time you.
