Hi welcome to everyone's favorite segment: Mailbag. In fact, it's Mailbag Dregg's for 2019 for this entire decade. And by dregs I mean all the stuff left on the shelf I'm gonna open every single last item that I still have remaining. Some have been here for a hideous amount of time.

so sorry to people who are set them in I picked them randomly or just ones that you know the vibe that but I'm gonna open every single one of them so this I'll try and keep it very concise for each one, but you know me, concise. Yeah right, let's get into it. First one comes from none other than Christopher J Gamma my esteemed amp our co-host for the last we're almost 10 years I think it's 10 years in February or something like that March next year. So yeah, if you don't listen to the NPR you damn well shoot.

it's still the number one radio podcast engineering show on the planet. So I have no idea what he said. You didn't clean me up so that's a look. Oh these are our cool little amp.

our coaster things excellent I don't know he came yeah I mentioned these I think it was get or are they stickers? No they they're very thin I thought our coasters yeah they're kind of a bit small for a coaster I guess but ya know they're stickers. So I think our Chris was giving these out at you know cuz he goes to tons of events and stuff. um so I don't know if you can actually buy them I don't think so I just have some. Maybe I'll give them out at the next Eevblog meetup perhaps? Um yeah, that was supposed to happen this year and well this decade and I was gonna say it's a, you know, a typical $2.00 Chinese one from eBay but it's not from Malaysia So I'm soaking it up.

Don't even need the knife. this one. it's a cat thing. What the hell, it's A.

it's a pink cat theme. Uh-huh Oh it like lights up and flushes a red light. It's got a USB and is that microSD on the side. Whoa.

God It's an Mp3 player. I How chintzy is that? It's not a Hello Kitty thing, but it's close. so just snap this turd open and there we go. Little Polly Put the kettle on battery and don't sit in so8 di I Expected to see like a blob.

Then is there a blob on the other side? So look. Blob blob. blob blob? No what-what? is that it? Are you kidding me? I I Expected blobby. Um, it's not.

It's just got the buttons on the double-sided point eight millimeter PCB and and like a sudden it's so sixteen package. What? The I Had no success finding any data on that whatsoever. So I Got no idea. Yeah, but look at that.

I mean it's so sixteen package and it does everything. It's got the full Mp3 player, the file system, you know, the processor to do all that, the decoding Mp3 decoding, and the headphone driver and everything. Wow You know what does that chip cost? and I have 20 cents something like that in volume? It's just nuts. Wow What I want my viewers in Deutschland in particular? Um or it? Bush I am watching that one? That's for sure I'm munching Munich Germany like it could be the German I don't know.

Alright seven look I'm gonna note. you know I don't read notes first spoils it haha it's a it's a beep grundig Wow so genuine Sony I've done a Sony Walkman teardown and it's it's a Grundig it's a beep boy Hands up you had a beep boy Wow good, another one another brand. oh it is. it is a Walkman just doesn't weigh anything Wow that weighs a ton.

This weighs nothing. Mega Bass Pink Classic. It might be a quick 2 minute tip. There's nothing in it.

Isn't that where they so cheaply built Wow How do you have any checked? No, you don't even. it's what a manual doesn't even. Oh that is so cheap ass Wow Just it just feels really chintzy and that's a genuine Sony one only. So this beat boy weighs a whopping 240 grams without batteries.

this Sony Walkman weighs 128 grams. It's a bit beat up I mean a bit. It just feels so chintzy this Sony Walkman oh it's like bottom-of-the-barrel stuff Wow I Get like I just got so cheap that's terrible Muriel What the what on earth happened there I Don't know. but Wow it's Grundy Dolby Auto reverse.

Oh it's got everything but AM Stereo made in Korea back when made in Korea was the made in China of the Japanese era you know all the best stuff was made in Japan and all the crap was made in Korea But no quality stuff now. And yes, before everyone starts bitching in the comments I am generalizing Of course you can get fantastic top quality stuff made in China as just as well as you could get top quality stuff made in Korea back in the day. I'm like chill out dude. choose your tape type and we're in.

Well what the hell is with the purple wheels? What? your purple texted us? somebody like their purple text or what on earth is going on there? Oh my goodness. Anyway, classic look at the single sided construction. how how are you doing is that? But that was. you know that was typical of the day.

No workers. Yeah, there's a tiny little is that the chrome switch down there and let's have a look at the bottom. it's all on the bottom. It's all happening.

There you go. Wave soldered, surface mount. It's at a decode of 87. they're not entirely sure.

Jrc Japan Radio Corp But doesn't that wave solder and just look messy as it's just terrible. Muriel: Wow, that's a shocker. What on earth happened up there? What flux on flux off? and seriously like did they use like gaffer tape to hold on the shield here? That's awful. What a shocker.

But that's all that's in it. Like that's it. It's a to chip solution and and just the the tape transport mechanism. They should drive motor down there.

and that's about all she wrote. You know, advanced flat flex technology for the day of course. and the Sony walkman. Well, that was two screws there, I don't see any on the other side and then just a couple of plastic clips.

I'm just going to rip the ass out of this thing here. We go there, we go. Oh, that's a bit. that's a bit fancy-pants here compared to the Grundig isn't it? Of course we're going to have ice.

I'm gonna have a Sony brand are we know that's actually not Sony branded? I'm surprised, but once again looks like a to chip solution. Don't need anything else. Anything else was overkill, But yeah, that's a bit neater isn't it? Got some flat flex going over here? Oh, that's right, that's the ribbon cable going over to. I didn't know there was anything on the front.

Ah, that's the mega base switch. Seriously, they went to all that effort to put this mega base switch on the front. so to do that they had to have that flat flex you like? They had to have this like switch PCB here and then the flat flex go all the way over there and they could have just had the mega base switch like on the side or something. There we go.

It all just comes out your that so you could. You could test that as one entire mechanism in the factory. but yeah, another flat flex going over to the head there and that's about all she wrote. no that auto-reverse rubbish on this one.

Usually you get your Sony branded parts on there, but nope, not this time. But anyway, yeah, that's that's a much better build. You can see the how they do do build them down to a price though. there's one screw holding that in there.

Even like minimizing the number of screws in this thing. I Mean that's three screws for this whole thing? I Think yeah, that's amazing. So that's going. That's the motor drive there, saving sense on the on the connector.

there just solder it directly on. no workers and we've got a got a trimmer there except to trim out the tape speed. Yeah, all right much in there. It's a nice low-profile motor in it.

Check out that. That's neat, but yet she's not much in it. really. that's why it weighs so little.

You know they're the only metal in it is the base of the transport mechanism. That's about all she wrote. So that's an interesting look at Sony's absolute bottom end though. I Don't think they would have made a lower end one than this.

Maybe they made one without the mega base switch perhaps. but so yeah, that's like bottom-of-the-barrel stuff for Sony But I did the job. Listen to your mix tape, listen to some MJ Thank you very much to Dennis I'm from Deutschland Let's go Ed doesn't have a description. it's a circuit board spoiler alert but I don't know for what that we'll see.

that's the trick. By the way, if you're watching this, I'm shooting this in 2018 I'm a day before New Year's but you will be seeing this in 2020, mostly 2019 2020. I'll be on walkabout somewhere when I release this video Oh Unfortunately, thank you very much watching for eight years. Awesome! thank you very much Dennis and two-cent some Christmas decorations.

Unfortunately Christmas is over next year though. Thank you very much. There you go, Sweet! So that's a neat little La package. I Don't think it's custom like just for me I think it's like this part of the product.

Unfortunately the website is not there listed but anyway we got this shows into here that's interesting I like that. What right can we? Yep, right off the bat that is a great solution. I Have not seen that before. That could be very handy.

Look at this. It converts. It's a winner Winner Chicken dinner converts a micro USB into a coin cell. Wow that like that's great.

That is a terrific solution. Look at that. it's obviously is that. think that extra board there is.

It's just soldered. There's no matching one on the top. So how is that? Maybe it goes through a hole in the center and then it melts on the pad underneath. Perhaps.

And that's how they join those two boards there. But that is fan-freaking-tastic I Love that. Wow, that's great. Even pivots.

That's the current winner of the 2020 Need Idea award I Like that. Actually, there's lots to like about this. I Think this is one of the best implementations of a LED Christmas tree. I've seen.

We've got a little single touch sensor down here to switch it off and on. and the LEDs look a right-angle mounted into these holes there so they're not directly staring at you. That's one thing I haven't seen on all the other ones because the other ones like they just blare at you right? The leads just go floor straight in your face. This one.

it's kind of bow tie they don't have I would have had plated holes in there, perhaps to reflect some of the light, but that that's really quite nice. so you know it's sort of like users out. it would go out both sides of course. so no matter which configuration you have the you know which ever way it mounts on the tree, you're just gonna get those lights like little Christmas balls lighting up.

That's great. that's that's a winner winner chicken dinner. It's one of the best implementations. I've seen what's the micro down there I Don't know.

Oh, there we go there. Light up isn't that nice and they look like the Rings They look like little balls. Ah, that's fantastic. That's a winner.

Wow And they're going to slowly fade. Are they different colors? That is great? That looks terrific. Well done. Very yeah.

That's the best implementation of a little. LED Christmas tree I've seen thumbs up, Tada. The coolest thing is though, the boards mount at right angles like that and we're in the dark now. and it just.

it's a standalone Christmas tree that's great. That is terrific. That's gonna be making nice our nightlight as well. I Think Huxley might like that next random one from the shelf.

to me it looks like it's just come from Michael O'Neill Um from South Haven we got hay. day. Ingredients are in Mississippi I Found this gem in the dumpster. thank you very much Michael Huge.

Was it huge Ozzy Knife only written on it? Yes. All right Huge. Ozzy knife. Look at this.

Yes, this is pretty much a replica of the Crocodile Dundee knife. It's close. Its close. Good enough restraint.

Let's have a look. It's a confused. Oh As it mentions, it's got a cookie. horoscope buttons.

It's got a horoscope buttons. French Germany Oh, it does. They're the shift buttons. Ah, Pure wanker.

II I mean astrology is right up there with homeopathy. I mean it's it turns on. Let's check it out. Got some quality Wang curry here from this no-name job.

it's just the model 38 one eight and look at this is star science. Give me a break Anyway up there. Yeah dot matrix not that 7-segment rubbish with currency store so translator you can go phrase Good Morning In French Bonjour German I'm good Morgan that yeah I won't try and pronounce those Bonjour no of course Dutch in Japanese I Do love how there was a disconnect between the LCD I had designer and the keyboard designer because French is like over here they're not in the same physical location that you'll notice the little annunciators up there. they're just just all over the shop.

so what's no worries in different languages? French No, no, nope, can't do it. Ah, now about Bonza, nah, it seems hopeless. Can't even speak strong I Love this. If you go into phrase good morning, good afternoon, good evening, goodbye, how are you fine? Thank you? excuse me you are welcome.

glad to meet you. But if you go the other way, watch this. Where is the something? Yep we're a bit embassy. Where is the embassy I'm screwed.

Where is the Embassy Consulate witness I Lost my call the police I have been faith help How many of the how many of these? How many of these should I take what's wrong, where is the my note and wipe my nose. Won't my nose won't stop? Great figured out how to get the stupid zodiac. You hold down the horoscope while you hold down one of the buttons while you turn it on. Anyway, Bloody ridiculous I Don't know Sagittarius What is this? No, but yeah, right.

So how do I The Archer? What fire, positive water load of is that all it tells you? Doesn't it give you you like daily horoscope or something? Zodiac sign: Leo: That's it. Now there's people that still believe this. Emily wondered people didn't believe religion to God Special Lucky Numbers: All we got a special lucky numbers here. We go: nineteen.

That's it. Nineteen. It's a special lucky number. ruled by the delusion, ruled by the Sun garbage.

That's it. Just a couple of blobs and interestingly, they look like suck 23s with the top two pins shorted. Yeah, What? That's that's where the peds like a what use him as diodes. No.

I didn't over here conferred it through older surface-mount diodes. quite common for the day. Actually, it's black and has absolutely no label. It's a monolith.

Yeah, okay, maybe it came out of something else and I've lost the right cuz the casian I do open things. He's gonna send me stuff with mail bag on it. so I have no idea. Magic cheese like charcoal black bubble wrap.

Wow, that's a bit unusual. That's a nicer. It's not silk, but it's silk like this. it's a ruler.

It's a ruler. So I guess I'd be able to find it on the interwebs. It's got constants and conversions and stuff like that ins black so that's why everything's matching. red goes faster.

but yeah, check it out. Please find enclosed a PCB ruler. sorry. And here it is.

the PCB ruler custom SMD parts a few references upside down. Let's there's a few other things I thought engineers, makers and students might like. It's yeah. cool, thank you very much.

David Dave David online alias and annum Innum and me and I'll link it in down below. There you go. What's happened NFC we're gonna me feel coil here and it's like 26 oz e a buck. So linking the Etsy store down below I rather like the protractor and down here I haven't seen that on on any PCB ruler before so that's pretty alright.

And then you've got that like sighs a different sized pad. they're not pads I'd rather have like a sizes like that which is what I've got on my cutter eevblog ruler down here and I don't know why. oh look my benches. my bench is flat.

look at that. I Don't know why you'd have a spirit level kind of thing, but okay. anyway. we've got a little lid here and a little magnifier that works a might come in handy.

Okay, you know the the warpage there is a bit much but good for reading part numbers. I've got some whole gauges and then conversions. stuff like that Constance I don't know if you need Constance on there. That's a lot of space for taking up our constants and and knowdon't and anomie space.

enemy space. There you go in the sky. Oh, you got millimeters down here. Fine graduations down there up to 160.

and on the top you've got inches. but it ain't labeled. It's not labeled at all. They're inches right down the bottom.

It's labeled though. There you go. Half quarters, three quarters. All that sort of chubby.

There you go. I'll link it in down below. Etsy if you did I think is it in Australia Anyway, it was like 26 Aussie bucks If you want to get one description of contents. the DD one two five, one, six, double, O two.

Everyone knows what that is comes from Mr.. Wang Sheng's in, but it actually comes from Rob Okay, so thank you very much Rob Hey, you know you can buy stuff for like one or two dollars delivered on eBay Oh well. that laser-cut stuff. What's it for? Um, laser-cut stuff for for what? There's no note.

Yeah, those numbers aren't helping me at all. Maybe someone knows. So we got these sheets. I Guess I can fit it together and figure it out? Maybe, but there's no instructions whatsoever.

Oh jeez, I Don't need a puzzle today. Really? brains not working that well. Well complete. Somebody tell me what this is a cutout for.

It's not like a Raspberry Pi I Can't think of what the hell this is. It didn't like them. People are probably laughing at me. Go not Dave Come on.

It's obvious it's that it's for that widget thing. but I like I Don't know. like it's got two different top and bottom panels so they're two different purposes. Like it's got a big screen on it.

And what are these cutouts here like I it's it's It's not coming to me I Don't know. Yeah, please leave it in the comments. If you've got any idea what on earth this is a case for. Um, because yeah, I'm drawing a blank.

Maybe I'm just dumb. thank you very much. Mark as a man ski from Green Bay in WI Wisconsin I think it is. um I don't it's a PCB type thingy spoiler alert Oh, we have a kid but that looks that looks Nixie that is a Nixie kid there little Nixie PCBs Cool.

And they're the adapters. I've done their videos on those. They're little um, like adapter boards for nixies. Cool.

So Marks a control engineer and he wanted a breadboard breakout for Nixie tube displays. as you do I'll link it in it down below. There you go. You can scan that to you, it's content and it's just.

that's exactly what it is. a little breakout board for nixies. We're single inline header pins that you can just plug into your breadboard and Bob's your uncle. nice for experimenting.

links down below. Actually, there's the address where right there s Z Y dot IO Huh? this one comes from Chris Gamble Again, second soccer. the serve in the one-mile bag. Unbelievable.

Think this wants to be here for a while. Sorry Chris Oh Christmas card. Talk to you on our top rated electronics podcast The Amp Hour Your longtime internet friend at Chris Gamble 9 years brings a tear to the eye. Oh, it's the yes, Yes, Yes, Yes.

Geez, this is old. This has been sitting there forever. This has been sitting there forever. Yep, Yep.

oh, it's the Led Zeppelin the Led Zeppelin You get it, get it. and I got all the parts for it too. Yes. I am octopi.

It's a note. Let me guess you making fun of the stationery, didn't you? Yes, no. I didn't make fun of the stationery. Oh oh, it's oh now I'm gonna make fun of the stationery.

There you go. Yes I Am Oh, I've been taking the piss for years. It never gets old. Yes, this was the DEF CON badge for DC 27.

How long ago was that in a galaxy? far far away? And yes, I said he showed me a prototype of this for the badge and I thought it was brilliant like that. You know the pun. it's the lettered Zeppelin it's got LEDs on and it's a badge. You know? Yeah, Oh yeah, yeah.

it's got the holes. You know you hang it, you hang it, like this. Is it weighted properly? If you if you have the two holes like that because they are offset, there's your two holes like that. and yeah I cuz this wouldn't have much weight.

so where's the center of mass should be right in the middle? Has he calculated? Has he done the correct engineering? I don't know, you'd have to like I'm solder it all up cuz yeah, there's weight and solder and the little lids and stuff they will add up. Then you'd have to, you know, precisely calculate the yep and measure that. Anyway, obviously I'm not gonna sorta on the like what is it? A hundred and fifty little? oh six, oh three, LEDs on here. Oh wow, that's an effort.

but yeah. I liked the Led Zeppelin I Thought this was brilliant and he didn't go ahead with and his city went with something much lamer than this and I couldn't believe it. This was a winning idea and he didn't go with it. Unbelievable.

Anyway, let me know down below: do you think I'll find info of the one he did have for that show and tell me which one's better? Might even if I remember I'll put a poll up the top which one's better? The lettered Zeppelin or the other thing he came up with uh hi, it was for DC twenty six but now it's a DC 27 badge. Yes, it's much better than the Good Fear Blimp I Can't believe he really looked the lettered Zeppelin and he renamed it The Good Fear Blimp. Why? Led Zeppelin is brilliant. Absolutely brilliant.

Anyway, it is designed to be driven here and then like I don't know how many LEDs are on there, you know? hundred plus LEDs didn't actually send me to lead. it's just the PCB Anyway I think the piece of is terrific, but this thing is a shitty add-on I Made and now sell as a soldering kit. It's just a blinky triple Five. This is he's getting to Blinky Kicad link I'll link in Chris's get into Blinky thing.

He's got to keep updating it every time he can to changes. That's the problem. changes so often he's got to keep I Think he's up to like a fifth or sixth version if he's getting to blinky or something. So he keeps updating his course anyway.

Online Course: Contextual Electronics I Cannot read this one at all. The they're like ancient. Yeah, it's like an inkjet. or they know their font is wrong on their label printer.

they're like Domo II know a zebra label printer I've got these and yet you can set the dithering I Think what they've got is they're set the different option in the zebra label label printer driver and it doesn't give you nice clear like things so it gives you you know, really fuzzy looking barcodes like that and they sometimes they don't scan properly and things like that and that translates into the tiny little font that they're freaking Dr. The DHL software puts in for the from thing anyway. so I don't know. all I know is that comes from Canada I can just read the word Canada Thank you very much we got opened I'm oh wow Cool.

This is obviously is this a Bitcoin wallet? It's it may be an open-source Bitcoin wallet opened I'm cool by now. If you haven't seen it go over to Eevblog to where I have already released my top cryptocurrency pick for 2020. I've done a video on that 2020 and beyond actually. so I've done a video specifically on their um cool open dime and Queen card only verify Wow it has no note whatsoever Oh it comes from coin coin Inc in Toronto Ontario Queen kite Inc Kate comes directly from the company.

Okay, cool value. Apparently this little calculator e things varied at 99 US dollars and these keys are valued at 37 bucks. So is this an open point I Opened Hardware wallet cold card in that cool. If that's open hardware then that's fantastic.

It's called the cold card and of course once you set it up it'll give you your new monix on the back and you have to write those down and don't let anyone see those because if you lose your are seed for you hardware wallet then well you can't recover it and anyone who gets accessed who steals this can take your coins easily like within a matter of minutes. So yeah, Wow can't believe that one's been sitting there forever. So there's the coin kite and it's I like the a little tactile buttons in there that is quite neat. and do you what? genuine Caution: it's got genuine on it so it must be genuine.

Of course, if you're buying a crypto hardware wallet only, don't be a fool only buy it from the original source. don't buy it on eBay Maybe like a genuine trusted reseller that's listed on the company's website, but don't ever buy one from eBay or Aliexpress or anywhere else because yeah, you could get a trojan anyway made in Canada I Don't want my Canadian viewers mark a rev - and there you go. I Like that. it's a clear case so you can see that it hasn't been Hardware modified or anything like that and that's a called a supply chain attack.

Of course you know companies will buy these though by the genuine one and then they'll hack him so that they can steal your coins. or they will hack the card one and there's a that's that's like a human type hacked I Can't remember the word like a social hack or whatever where they prey on your ignorance of how these Hardware wallets are supposed to work and they supply you with a card that already? That's They've already set it up for you and they've supplied the mnemonics down here and the code phrases so that they already have the code phrase intent And if anyone has this card that you're supposed to set up, you get a new hardware wallet. Of course they all work like this is that you can get up to like 24 is 12 or 24 keywords and it generates these the first time you power it up. You're supposed to write these down and then go lock this in you you know, safety deposit box and and but if anyone steals this, they can immediately take your coins with any US other software or Hardware wallet within minutes.

So yeah, you lose this, you've lost your money. So what they do is supply it pre provided they've already set it up and you and like they'll have like a fancy printed sheet with the words printed and look all official and stuff like that. Oh I've got my secret keywords but they've got the keywords and then they'll wait a while and all. They'll get alerted once you upload a significant amount of coin into their system onto the blockchain of whatever it happens to be Bitcoin or one of the old coins or whatever and then they'll just take your money because they have the key code so don't get supply-chain attacked.

These ones here are open Dime and I'm not sure if I like this concept plug into USB Open Index.htm Follow the steps I'm not sure I like the fact that you've got to plug in a USB and like run something from the Usb once again, that could easily be a supply chain attacked at legal tender on the blockchain inside in countries What? Anyway, and yet Bitcoin It's open dime, but this is of course genuine. You can trust. It's genuine from the manufacturer. So I wonder what the where they put the test elations on the side edge there? Oh that'd be our programming of course.

Yeah, that'd be out. That's how they program these things. That's kind of neat I Like that. So yeah, that's Jazzy the keyring hole.

They have plated that so it's not going to wear down so you can carry it around in your keyring. Okay, I won't try this in this video because it'll just make it too long. Might have to do a separate video on this for those who are interested. Maybe on my second channel where I put some crypto related stuff.

Anyway, watch my second channel. By the way, if you want my top crypto pic for 2020. I've released a video over there on TV blog too. Anyway, this open time.

the concepts actually quite novel. What it is is it's just a USB stick of course. and you it's not set up yet of course. just like any other, you know physical hardware.

While it shouldn't be set up until you physically get it, if it is, then it's a scam. then you plug it in it appears as a USB Drive and then what you do is you drop in some files they recommend like photos so your own personal photos, photos of whatever I don't put anything you want aren't drag it in and then it uses those files as a random seed. a random like seed to generate your private key and then the private he is stored inside here and the only way to physically get your private key out from this I and then you can of course use this like as a Bitcoin wallet and you know spent send and receive money on the thing. but the only way to extract the private key in that case in is then to physically punch out like put a pin strong pin through this hole here and that what that does is that physically D So physically removes this resistor down here or you could cut off the heat shrink and you can do solder the resistor and then that instructs the micro to actually output your private key for this things.

So it's an interesting concept. so if you want me to do a separate video on that because these like videos to like review these hardware crypto well let's say you know take some time I've got to do it like on a cold machine I wouldn't do it on my real machine here I've got you know, do it on an independent machine and stuff like that just to make sure I'm not being scammed. and same with this physical hardware wallet here. So yeah, let me know in the comments.

if you want to see these things powered up, I will link them in down below. these are these are that's a rather interesting concept. It's been around for a while. They did actually have a previous version where you had to push out it was bigger and you pushed out I routed out section of the PCB in there and that would do your private key.

but now they've gone with this pinhole resistor idea and they've made it smaller and a bit more robust. and it's got nice rounded corners on it so you know, whack it on your keychain and stuff like that I don't think it's any got any two-factor authentication capabilities I think it's just a Bitcoin wallet and it I believe it only supports Bitcoin That's it. So yeah, leave your thoughts in the comments down below if you want me to review these properly: 1 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 I'm already up to 11 packages. This is getting ridiculous.

12 13, 14, 15, 16, 17, 18, 19, 20 21 I've got at least 21 this may. This may have to be too, but 22 Another big one here. like no, no, no, no, no, thank you very much Marseille Kowalski silent Jay in there somewhere Middletown Ohio Thank you very much It's kind of weird. Alright, like my spidey sense says, if I just rip that open I'm gonna be cutting into something and I would have been right if I went right along the top.

What's your program? A lot? Way too much. I Actually love the don't turn on, take it apart. Oh we've got some processes Polish engineer lives in. Ohio Excellent.

You send a quad-core 55:20 I cracked the package open to take a look, but the diet was sordid. Oh okay. cool. Oh Take a look at him.

Oh no, did I count those on the shelf I put some empty ones back on the shelf so may see if I'm pronouncing that correctly. Almost certainly aren't as comic gutter trying to take this Xeon processor apart. Sandy 55:20 and let's have a look. What happened is he tried to get the top heat cap off and it turns out that the dye of course is bonded to that.

It has to be physically bonded in order to get the heat out. And what one wah-wah it? It actually split the dye in half. Get in that apart so you can see the black eye gunk around there. So what we've got is like I don't know how many layers in the actual dye itself.

you know, 10 12 layers or something maybe. But yeah, it completely split the dye in half so you can sort of see some circuitry on. They'll put the macro lens and I won't get out the proper microscope because there's not. You know it's it's pretty how you doing.

It's not a proper you know, a sulfuric acid diffusion. You won't get a beautiful dye shot out of this, but we can see something so you can see some of that. but it's just like totally cracked. Not much you can do there.

unfortunately you can't actually see at least some of it and see. Yeah you can see some structure there and this one down here. like there you go. But yeah, it's not like a no bars chip teardown or anything like that.

they're the Masters of that. They do fantastic die shots and so just just the color you getting them are absolutely brilliant. anyway. thinks that's interesting to see how that is like really bonded on there I don't know how you'd actually decap these properly would you have to? you know, heat it up to ID cap that and then you know sulfuric or whatever acid attack the thing.

and how would you get down to the different layers and things like that? There's there's various techniques for it, but yeah, it's pretty special stuff. I Like how the colors change. This isn't a great example, but look purple, green, and then orange or whatever. That's pretty neat.

Thank You Walter Jack something I can't read it cuz they stuck a label over the top of it I'm from Allentown PA Pennsylvania that crazy Aussie bloke Mayo Babe here. Box seven, nine for nine Buckland Hills New South Wales Two One five, three straw Leah not Austria for those playing along at home. If you want to send me something in 2020, please do a plan to keep my obey going still on my rocking chair. everyone.

Favorite segment: My own bag. It's a winner. Winner chicken dinner. Scratchy, well done.

Cheers to Philadelphia I Said Pennsylvania day it's filling Philly I Recently starred in Electronics Maker Channel on YouTube Excellent And like all such channels, your work is a major inspiration. Takes you all the hard work in his hard. Enjoy! If you win, send it back and I'll split it with you a Walt Overkill Projects I Like the name of that channel named Overkill Projects I'll link it in down below. Excellent, Thank you very much.

Scratch it with a knife of course. my don't shave while I'm at I think it needs a sharpen? Alright, whoa. the knife might be scraping too much off. Don't use knives to do scratches.

they really suck. He's an Aussie 20 cent coin instead. Lucky Platypus. Let's go.

Oh yeah, that's infinitely better. Nice. I Don't use them I think I really screwed the pooch I'm one of them. No, Unfortunately, we've come a gutter.

everyone can double check, but you got to match the number at the top and that dodgy one down in the corner that's a seven I believe. So yeah, don't gamble, kiddies, waste your money. It's good to dream though. thank you very much.

Lucas Macaron Sorrento and Victoria so that's from straw Lea Bloody Rippa um Trump Trump are here for the thumpy here trumping here. Sorry Thumper, you have to get a Trump in there. Give it in the key words but some boards. Oh cool.

This is awesome actually. I Had this on the list donkey's years ago. It's a it's a little too shape a hard drive. well that's that's worthy of more than a two-minute teardown in a mail bag.

that's a little like what one-inch diameter hard drive don't know the actual size of that cool looks like with a two of Oh Awesome. sorry yeah, they'll have to be like separate separate Ariane videos cuz I really probably find those interesting. don't know where they come from. there were little Toshiba hard drive made in Japan all this stuff's made Japan Yeah, look at that groovy huh? There is one that I've opened but I wanted to do a video on that so I'll just crazy Crazy potato we mailbag I think I think I've opened it before actually I just put it there so I wouldn't lose it crazy Aussie Bloke Mailbag yep from Germany thank you very much I'm doesn't say who it is that is a Dodgy brothers light bulb.

No note did it come straight from my straight for me by Germany on it. Yeah that that's a decent just the weight of it. You know that's dodgy as well. 2-minute teardown.

Geez, that's gonna be a shocker. Yeah, my spidey sense tells me this is going to be an absolute two just ways. Absolutely nothing. No name.

oh that's crack it Over there you go. It's just soldered down in there and this is just chintzy plastic. There's no way heat dissipation there. Well that is as how you're doing as they come.

Look at this line in here. this is 240 volt. AC We've just got a capacity of divider here. that's it.

Goes into a bridge rectifier and there there's no constant current drive. There was a chippy in there, but I save a few cents for that bug of that. So it's just a a preacher rectifier and some chopper resistors and a cap on the output. I mean come on, come on really Otta I say garbage.

Oh wow from someone you are sorry I don't know I Think it could just be an eBay II thing. let's have a look know what it is? Yep, people keep sending them I don't know I'll keep it shrink-wrapped I've done many of these before I'll keep a shrink wraps the two-dollar multimeter. Um, might be able to blow it up with an electric fence tester that I um have. So I'm gonna keep that shrink right? special.

Lucky last, we have a book. I'm spoiler alert. We've got two thick envelopes love to Vic envelopes bit of a de Becque fanboy I Use them in houses for insulation. That's an American thing not insulation for like I don't know some sort of wrapping on houses or something Duane I Playground Warren Injuries K-keep right if you're into your Arduino is jeez, that's like 300 pages, 300 pages of Arduino II Goodness Ah, it's no color black and white.

That's all right. Save e save the whales to your Arduino projects. It's probably gonna do the business. No Starch press.

Yeah, I've had that one a while. so this is geeky projects for the experience maker and No Starch Press. Oh I do actually have an open invitation from No Starch Press if I ever want to get a book published. Anyway, that was info about the author setting up useful schools reaction time machine.

So ten different projects over three hundred pages. So uh, that looks like pretty comprehensive. How I have the schematic determining reversal thresholds using H bridge to sketch the shield. That looks like pretty comprehensive if you want to delve into it.

Well, yeah, all the photos drilling the boards? well. the reaction time machine. there you go. I'll just go through one of them I Read history.

How does the game of the schematic goes? It will. schematics pretty simple. There's nothing doing there really but step-by-step red board and then the sketch and stuff like that. Not a lot of comments in the code, stuff like that, but yeah, that's and then physical construction.

how do you want to construct it? So there's lots of you know, constructions, things, stuff like that. so basically ten of those. they probably get a lot more advanced. the mystique of the automatic watch nice, and yep, probably gets lots of, you know, physical manual construction techniques and stuff like that.

So notes of caution: things like that. that's probably something dangerous there. So oh, it's pretty comprehensive. Lot of works gone into that, so there are a few in here are more advanced.

Arduino Projects only link down below. Check it out so they have it. that's mail bag for, well, the 2010s, that teens, whatever this decades called. what's the next decade gonna be called I Don't know what's the Roaring Twenties last time.

Maybe it's the yawning 20s or something I don't know somebody? come up with a good name, please. Anyway, I'll be back with mailbag towards the end of January is when I'll be back. So yeah, so I'll be back in 2020 for my usual eclectic mix of stuff. and I hope you have a good holidays.

If you get a break, go somewhere. go walkabout like I am. Catch you next time that a decade Bloody hell. I've been doing this for a decade.
