Hi Welcome to everyone's favorite segment My ol' Bag! Let's get straight into what this one comes from: Martin's lessons from Latvia Hi to all my Latvian viewers the name It rings a bell. I think Martin might be aberrant Martin's sorry, might be having a second suck of the serve. Now what's the deal with this plastic? I'm not sure. Let's go.

We got here. It's a super something. we have fun. More fun aboard.

Wow There's a note in there. read that a second. This looks like a huge board. Just like a board.

feels like a board. Everything else. Wow Look at it for processor server motherboard Wow What a beast. I Believe it's some faulty jeez.

How many memory slots 2, 4, 6, 8 for each processor and Wow wow what a beast. I don't even know what size that would be. Is that like? Is there a like a like an industry standard for this particular size motherboard? that probably is I don't know. sorry I'm not into serve up motherboards and whatnot so it probably takes you know Zeon's and or whatnot.

So Wow thank you very much. Martin's very nice. We'll take a quick look at it. our house just about to say that Martin's was the one who sent me my Z on motherboard that he he says that he sent sometimes sorry at plus the Zeon's was not able to fulfill your rendering needs.

it actually was I'm using it. Um, unless somebody sent me to Z on motherboards. Anyway, yes, I am certainly using the dual processor our Xeon motherboard I think somebody else sent me some Zeon's as well as somebody else sent me some memory. and I've done a video actually building my Xeon rendering machine which is what I used for rendering here.

Um, a lot of the limitation for my rendering actually comes down to various software and codecs and things. Um, but no, the the dual Xeon processor machine that I'm currently using is a beast and it renders very quick in terms of well, at least for doing things that can actually use all the multiple cores properly like a handbrake for example, doing transcoding instead of video rendering from my Sony movie Studio slash Vegas editing software, but in which is a bit slow when I'm doing 50 frames per second like you're probably watching this one out. But that's a codec issue, Not it because it can't utilize all of the zeon cause so um, but handbrake, it's super quick. So thank you very much mum.

well check out this beast. It's a Super Micro H8 Q g6 - F for those playing along at home. Yes, I'll link in the datasheet and all the paraphernalia down below, but let's have a quick look at it. Four processes.

No, this is not a Xeon as I Guess before, it's actually a G34 socket here. that's for the AMD Opteron 6000 series process of what ones that actually supports I don't know, whatever. And we've got eight DIMM slots per processor for a total system memory of one terabyte. What would you need that for? Hmm I don't know.

but obviously this isn't your standard desktop or gamer. PC it's designed for server stuff which can utilize all the cause. high throughput, all that sort of jazz standard. PCI Express some over here and basically what this you know like the CPUs do a good chunk of this I mean it's basically these days I mean all you got is the CPU Of course, in this case, four of them.

you've got two North Bridge processors. These are AMD ones, I'm SR 56 90 and SR 5670. Not sure the exact differences between these two haven't really gone into it anyway. So there the North bridges.

How South Bridge is here. This little puppy is poor little sad thing under here which doesn't get a fan? or why are these ones so special? And we've got a No. Vuitton Bass Board Management controller up here. a Gigabit Ethernet controller here.

It's got two Gigabit Ethernet ports on the thing and this is your SAS RAID controller down here. Look at the how many, two, four, six, eight, ten, twelve, at least fourteen solder connectors. Unbelievable. and pretty much you know, not a huge amount else.

it's just really, you know, support stuff, power things which we'll have a closer look at. Look at the amount of arm extra power connectors on here. it's I Don't know what the total power consumption of this thing, but it's an absolute beast If we have a look at the back here, not a huge amount on it. There's some support stuff over here.

It looks like there's some sort of interface driver over there level translate. that's something like that. But yeah, it's basically just like a huge amount of controlled impedance routing as I've mentioned in many videos. Of course you can see all the controlled impedance differential pairs going in here.

This is why they're all funny and sneaking. no, somebody wasn't drunk when they actually laid this thing out there in length matching all of these and that's the way they lengths match. They add a little Wiggles in there and then you've got things like the under. the memory here.

they've got massive ground planes under there. even though this is going to be like a I don't know, like a twelve layer board I'm something. I'm not sure the lay account on this beast, but it's going to be absolutely enormous, but they put those back on the bottom as the DIMM modules and over here we've got some more routing. This one curiously has routing through like half of the dim dim connectors.

Here you can see see all the via you can see all the V is there. from the din connector. there are surface mount. Of course they're not actually a through-hole so the but yeah they decided we need some round in here and our we don't need any round in here so let's just walk in a ground plane.

These ones over here didn't need it, but obviously these ones up here did and another one over here didn't So that's all just a part of your layout considerations and things like that. as our PCI Express slots over here, more stuff coming down. Oh Beautiful. There's that, that's probably a level.

White translator looks like an IDT one note, Cypress is it I can't see on the screen here anyway. um, power down the bottom, but a bunch of miscellaneous stuff they're going to that looks like some power control DC to DC converter logic down there. So let's have a look at the power supplies. and a massive critical part of getting a huge system board like this working is the power supplies.

And look at these they've got and these are all separate DC to DC converter chips I Haven't looked up the part number but of course they did give aways a little these big inductors here and we're going to have they're probably polymer based electrolytic caps there. We've got our diodes over here and there's a whole bunch of these and there's just banks. And banks And banks of these. What have they got? You know how many of these do they need per CPU or these pairing? just a CPU Some of them maybe are separately powering the memory of the DIMM modules? perhaps? I Don't know.

We can actually flip this board over and I'll show you those they're the ones I said we saw before there we go. They've got some additional controllers on the bottom there Wow And there's just I Don't know. It's like half a dozen banks are these things. So I'm not entirely sure how many rails the AMD Opteron processor takes and whether or not they're all dedicated to those.

But yeah, I mean each processor has its own bank? There we go. Another one up there. There we go. Looks like there's some regulation under there and over there.

Tons of it. What more down here? these are be powering the Northbridge here. Wow Power everywhere powers everything. and there's the socket for you socket aficionados.

Little pins. They pretty one of these things cost a bucketload. One of the most amazing things about this board though is imagine what the production yield on this is like. Imagine trying to get right the solder in process on these connectors and all the dim sockets and all these huge you know these are probably thousand pin BGA's as well and there's just tons of them.

If one little thing fails in here, we'll get that entire border screwed. Imagine how much effort goes into just getting the reflow manufacturing process correct. Just a reflow solder. This thing, let alone all the you know correct pad geometry for the socket.

So though once you've done that once, it's okay. But just getting the thermal profile right I mean you can't just whack this in your toaster oven and expect it to work, you wouldn't be able to just even whack this thing in a regular, you know, professional reflow oven. Just getting the profile right and the process and the type of machine you actually need to reflow something like this and get everything correct and the thermals of the board as well. soaking the thing and I to be absolutely critical because there'd be a ton of ground plane in here which really hates these.

What A takes a lot of energy to heat them up be they stay hot for a long time so they're difficult to work cooled down. so you know the risk of tombstoning and other issues caused by that is absolutely massive. Just yeah. I Would not like to do this at all I would not like to be an assembler going.

we need you to make this and give us a high yield to well. so thank you very much Martins for sending that one in. Definite keeper. It's like a you know you can almost frame it, wake it up on the wall.

It's beautiful work of art and yeah, maybe we can I don't know, do some something fun with it I don't know what but yeah, its non-working Martin says so yeah it's a fire board I Have no idea what could be anything but wow what a beast. thanks Martin's next up one from straw Out of all my Australian viewers bloody rippa, it's sent to that crazy Aussie bloke who loves Sony I Do like Sony Get and yes sorry I still have a few Sony retro items for tear down so maybe hopefully I can do a Sony retro tear down to earth from the viewers of that crazy Aussie bike in Queensland Bloody Queenslanders from Brisbane I'm and it's some no folding thing. Oh there you go that's not high diving quite. Oh, here's another gem to add to the collection.

thank you very much Andrew and Jim from an unnamed government department. Hmm please let's not let the based in Canberra which is where all our bloody politicians are based. There's my phone. Again, don't get too many calls here at the lab.

it's just the wife. Let's have a look. It is a bit a Sony gear or in the original box. Look at this.

Dummy me, it's a Sony CD 2 Material Mobility for enjoying DVDs and CDs Behold this magnificence from the 90s. Look at that beautiful power burn. Yeah! Portable Cd-rom drive. Yeah, a little bit confused.

there's actually a portable writer. It is a portable CD writer, but it can do playback as well. It can do memory sticks and it's actually an audio playback device. You can? you know? actually that's a combo weird ass combo thing.

hmm and go the custom battery cradle. haha. look at that. now you can just plug this beast.

How do you plug it in? There we go. Do we plug it? Yeah, dummy. Dave There it is on the bottom and this flips out and it plugs on Dear cradle like that. Yeah! I Got the 1990s.

this is 2003 technology, thank you very much. Mp3 playback would have been pretty state-of-the-art for the time, wouldn't it? There's our custom rechargeable battery, some sort of Lithium job and through the magic of YouTube we're in like Flynn some decent shielding in here I Don't mind that at all. Geez, Look, they've even got the little look well shielding tab coming over on to it's at the top of the motor there. I Like that but more interestingly look, they're using flat flex as the connecting looking see one big conductor inside the flat flexor.

They've even taped it down thank you very much so it doesn't flap around in the breeze. they've actually use that to AH actually is that spun off from that one? Oh sorry. Ah, terrible. Vince Terrible videography here.

but yeah, they're using that flat flex single conductor to actually join the screws to actually connect the grounds together. Very neat. No surprises for fighting some Sony silicon in there. Sony do a lot of custom stuff.

What's that 3u puppy there? I don't know. Google it? Oh um, yep. there we go. ARM Processor Bad genuine trimmer Wow What are we trimming? I'll tell you what, there's a lot of integration on this board and check out the fit to envelope design in here.

Look at that. This is obviously audio and power supply stuff cuz there's our audio output there probably audio output driver there, but all the caps in here and the inductors all you know vertical parts. They need a fair bit of space and they all fit into that envelope down there. For spring fell out, it's not gonna work anymore.

There you go. the old light pipe. Look at that. The choice of system designer champions everywhere.

Little Oh A 205 let in there. That's a way to get the line out, the side beauty and more of the flat flex ground in from there to there, completely ruined by this ugly wire. even though it's crimped and done properly and beautifully and taped down, it just let's see what's under this puppy. Yeah, more.

If we got some rubber insulators on there, Have we? Yep, but hotter? Nah. There's our drive mechanism. nice and I couldn't resist. And of course your laser diodes in there somewhere and this one's a keeper.

It's just fun I don't know. might be able to do something interesting with it. And there's the ejector mechanism as well. You can see that I'm in there.

It's got its own little motor. look at that drive on it and it's electronic. So you push the eject button over here and it's all the way and all the stuff is over here. So yeah, not just manually.

They went to a lot of effort for that. and don't you just love the jazzy little remote with these? This Sony's with the LCD probably plays like the track name, the Mp3 track title or something like that. Ah beautiful that rock that on your lapel. So thank you very much Andrew and Jim from the unnamed government department / AG oh hello, maybe I don't know.

Hmm. thanks guys. And yes I am going through sighs order yet again being a bit naughty. Just want to get the big stuff off my shelf.

Thank you very much. Where is it? Rich, good? A rich? um, he's from the United States of America in Jamaica Plain to be exact Jamaica Plain the plains just plain. There you go. Hmm.

All right let's have a look the riches sent in here. It's multiple items. There's three items on the customs declaration. We have a note how I usually just skip the notes.

Do we have Oh the original candy water, the American classic Nico never heard nor seen of them. Here you go, neck. oh oh give those a bell. oh we have a crusty well ho hang on, hang on Jesus some interesting stuff in here.

There we go: I'll just crack this open I Do actually have another unit up there so once again it'll be a multiple tear down haha. Wow The Garmin GPS three plus I could only dream about that when I was a geocaching back in The day with a little compass as well. Beauty looks like it's um, been? Well yeah, it's got some velcro on it and interesting wedge shape so like it can sit like on a bench like that. I guess Like you know, maybe you're good for boating and stuff like that.

Perhaps you can like wage it up in the console or something like that would be my guess. Anyway, that was probably the Ducks guts back in the day. It's gonna have a helical antenna in there and Beauty wonder if it still works. Probably does.

They're super reliable. these things. um all these old GPS is I've looked at. they always still work.

We had asked custom for pin connector on the back but awesome So we have a dumb and GPS are good. another GPS I think and we have a probe style oscilloscope right? It's a red check rat check for originally $89.99 Wow There you go Radio Shack right? Even comes with a three and a half inch floppy is probed it off for Windows and DOS version 4.1 So got a date on this thing 1996 Tandy Corporation. All rights reserved. Ah oh geez.

2-minute teardown Beauty The original candy wafer made in the United States of America since 1847. these are equivalent to I guess fruit tingles here in Australia I'm not a big fan of the cut way furry thing I think I Much prefer the fruit tingles. Hmm. Tastes exactly the same.

All right, let's see if these Bobby Dazzler still works well. It does. but oh look, there's some lines on the screen there. Ah, it's the GPS 2 plus or is it 3 GPS 3 plus searching the sky I Don't think it's gonna find too much here in the middle of a concrete building.

Hmm. but check it out. This puppy rocked a full 12 channels back in the day. The original model? well, the manual for the GPS 3 dates to 1997, but this plus addendum this is the G and GPS 3 plus a dates to 1999.

So let's party. Look, it's 1999. Wow Check it out. That's surprisingly a bhaji, but geez, look at the the RB electrolytic edge is it's glued.

at least its silastic down to the bottom there. but they got the leads going all the way out there. It's like it was an oopsie and whoops, we're gonna add some capacitance or something's. not quite stable enough and even this puppy wasn't enough.

and they had to add this one over here. So what the what's going on there? Anyway, here's here's our receiver and that's coming from now: Helical antenna I Don't need to rip all that apart, it's just a two minute teardown and with that under the can there which is soldered down by the way, I won't take that off. probably maybe an older first generation serf chipset perhaps? I'm not sure of the exact date on that probably around there little bit of look. a little budge on the RTC crystal.

there. There we go. thirty two, point, seven, Six, eight Kilohertz watch crystal and then they've just silastic that down bit a hot snot there down a why they didn't use ass proper surface mount job I Yeah, it's just surprisingly a little bit. how are you doing for it like a you know, a leading edge Garmin product? Well there's something you don't see every day.

Intel 386 IX Processor down in here. Wow, that's a fair bit of grunt. My what? you know, not. Maybe not optimized for the job.

Maybe they chose that because the development was easier perhaps. but yeah, that would be sucking a bit of the joy juice. You can tell this thing's designed for the marine environment. You know the big rubber seal around the outside here and the rubber look rubber seal on the custom power connector at the back here.

and some of the you know the screw in here has some silastic on the bottom of it and do we have? Yep, we've got a rubber seal around the battery compartment there for the for doublea's Ah yep this is designed to sit in a boat. Maybe you know, like in the front console or something like that whip up you helical antenna. You gotta have an erect helical antenna and Bob's your uncle and Rich reckons there's a myth about these Necco wafers. These things were inspired inspired a useful manufacturing shortcut for the first radar systems during World War 2, but every trace of that tale seems to been wiped from the Internet At least they taste slightly better than something you'd find out of year 1940's electronics.

Excellent. Oh, look at this thing includes Windows Windows 95 Ms-dos compatible software Wow because yeah, you want to like get cereal out of your handy scope. Mmm your probe scope sorry Cat number 22 310 for those playing a look at home. Ah, beautiful.

ideal for on-the-spot testing of electronic circuits. Selectable input ranges: one volt 10 volt, 100 volt 20 Meg max sampling rate 5 Meg effective bandwidth none this equivalent time sampling rubbish about a 16 by 32 pixel LCD Oh goodness, the RadioShack probes scope. But look at this custom manufactured in Germany for RadioShack a division of Tandy Corp in Fort Worth Texas And of course, the thing with this. There's no ground attachment on the front - high frequency probing rubbish art designed to connect to the circuit under test.

So Pierre, you managed to find a point on your board and hook these puppies up. I'm just like logic probes back in the day, you know? And yes, so that's you. don't need the ground attachment there because it's coming through the system ground over here. Goodness look at anyway.

it's gonna be absolutely horrible, but you know I Guess it served a purpose back in the day. it's a live probe scope. It requires that 90 hour 15 volts in here. But yeah.

okay. what do we do? Probe scope Nate Somebody went to a lot of trouble to do that Ac/dc coupling. thank you very much. And Ground G's got everything.

It's even got a funky zero level knob. Oh yeah. play with that theme all day. Okay, so how do we actually make it work? Do we push this button? I Assume we push this button here because it's just sitting there.

Oh yeah, there we get Visions 3.0 1995 Here we go. so wouldn't even power on yet? Oh there we go. We're in Tada. I Can make it do something? Can I pick up 50? Hertz Hum.

Here we go. How do we change the time base? Press it. Oh yeah, there we go. Hundred one hundred nanoseconds.

0.5 microseconds. There we go. We're going to get there. It's actually like you can't.

You can just go in one direction. That's it. There we go. We're starting to see it.

We're starting to see it. Hold on to your hat, Tada, We have our 50 Hertz What a Bobby Dazzler And here's inside. and Germany Alright, who or what is Bblingen G'day Bob Oh look at that. the LCDs just hanging there flapping around in the breeze.

there. That's just so. that's a serial interface job. You can see the number of pins.

very small. Looks like there's a micro with some firmware and what's that puppy? What's a Zet? MDU 1825 Hmm Wow A Cop 8 Process Free all you Cop 8 fanboys. There's gotta be a couple left out there. There you go.

It's actually a Wittig Test technology. It's the Aussie Fox Beauty that's not Ozzie that's Aussie Aussie right? It's still as yeah. No fail. Anyway, witty somehow.

I don't think there's much overload protection going on there. Straight over to the switch down here and well, yeah, there ain't much in there is there. Hmm. thank you very much Rich for sending those items in.

Interesting tear downs. Urgent crowdfunding ends 30th of March Awesome. Let's crack it open thank you very much Ben Wang He's from my crow's nest here in Sydney So that was the red zipper thing. The red zipper thing failed.

Ah bloody is this A. this is a genuine Australia Post envelope -. ah garbage. Anyway, put the red pool tab on there.

make sure what he well works. We've got a bear board. let's check it out and Ben's had a second suck in the South Here he's from North Sydney boys high school year 11 student and you might remember it's a new improved version of what we've seen before the board. The perf plus 2 allows any two points to be connected together with 0 wires and some solder bridges.

Project is currently over 200 percent funded beauty and will end on the 29th of March So link it in down Below is just sold in. A couple of things on here to show us how it works. and he did the remote boot thing. So what thirds suck of the South Hmm here it is.

Doesn't look very impressive, but it's a proto board. that's the hop. That's the whole idea. Let's have a quick squeeze so if we take a look up close, you can see that the traces go in one direction here.

So it's a big strip, just like a very board. So it kind of combines like a very board and matrix board, but you can actually dissin, but you can, but by default they're all disconnected as opposed to all connected together with a very board. and then you have to cut away these ones if you want to join them up. What you just do.

Little solder blob like that is tiny little what is it? No fires in like sixth hour, eight hour or something in there and you just put a little solder blob across. and of course all the ones. They go in different directions. so just like routing back in the old days, these ones go vertical and these ones go horizontal.

Very, very flexible. I Love these things. So safe reeks. Sample this Admiral processor here.

You've got that one trace going directly down like that. so if you wanted to, you can just solder. You know you have to join that pin to that pin. No worries, you just join those two together with that one strip and then on the other side.

Here you can actually then you've got them going in the other direction. It's quite flexible. So like all these are proto boards like this, I like this one and they've each got their own unique niche you. so it's worth having.

like many, like, there's no one board that is. You know, one prototype board that's suitable for absolutely every project, every requirement that you come up with. So it's worth having. Many different types of these are proto boards just in your junk box so that you can, you know, whip them out and do a quick project.

This is quite neat. well worth having. In addition to your standard vero boards in addition to you, you know your more functional ones for all your surface mount with stuff and things like that. Definitely good work.

Ben Oh I Only saw the second page of this thing and Ben's got himself a patent on this thing. Do you believe it? The Field configurable electrical routing matrix for electronic prototyping? Well, okay, good on your Ben if that's your thing of that floats your boat. Next up one from Deutschland I Do all my German viewers which is a very significant part of my audience. thank you very much.

Um, ich Ike di ke um Chef thank you very much. Okay I quit your bike. that sounds better. sorry if it's wrong.

Oh nice flowers on the postage stamps. Anyway, after let's check it out, it's a yes. Okay, Oh Maybe give it a spoiler, it's something. Texas Instruments Let's check it out.

Wow and I Biko 83 calculator Wow Simple four-banger as they're called what well in the calculator world. Therefore, Boehner is a four function calculator and geez, yeah! Wow made in Japan all the best stops made in Japan Whoo! All right, let's have a look. Thank you very much Eight You sent a note, but that's not the Texas Instruments theme. This is the Texas Instruments thing when they came in a handy carry case.

yes, rocking up and just cruising the streets. You know? Yeah, I'm ready with mine. Whatever is the TI 50:29 Oh, look at that Wow rockin' the streets with your heart. Once again, it said yeah, it's a four banger.

It doesn't even have it's got totalizing and stuff like that, but it doesn't really have any financial arm stuff. It's not really like a one of those proper financial calculators. Eva it's one of those printing calculators thingamabobs. We've even got the old roll and I'm an accountant still use those.

Apparently they still sell up. Um, go see Yeah right two minute tedium. So like ascending these two puppies from 1975, here this I'd be CO and this Ti for all you Ti fanboys out there I'm it from about 1990 and check it out. Vacuum fluorescent display.

Isn't that a thing of beauty? Way out and it's a sharp for the win. Check it out, it's alive. Oh, it's doing. Yep, there we go.

Yep, there we go. So we know we don't win the chicken dinner. Beautiful! Wow Crusty. Check it out and we got ourselves an arrow Epson printer.

There we go. He's playing along at home marked 19. There we go. But look at this.

There's nothing in it but this puppy look. they've converted the dip into surface mount. Well done. Overall, that's just a pretty horrid bunch together piece of crap.

really. I mean look at these Luther caps just tacked on the back here. Ah, you know this is production, but uh, you know. uh, a label is probably cheap in 1990.

Mm-hmm there we go. You can see down in there how they print the things that's effectively like a daisy wheel. I got ourselves a FedEx one. thank you very much Edward Hopkins um who I presume is from Oh no I hope that's gonna save the U.s.

um based on FedEx and its operate everywhere. but you know? Anyway, I'm from Senegal Thank you all of you Always in Senegal um duck I'm not pronouncing that correctly. am I sin ago? Senegal is it's uh Sena goon I don't know that's how I saw Z's might pronounce it anyway I don't know Oh postcards presumably from the country which I can't pronounce correctly. That beautiful and a victorious looking dude.

It turns out it would is actually our formerly from the US I'm originally from the US now in our deck Irene Oh cool, awesome and we've got some. Look at this. Ah makes the skin crawl cheapy. Do that on the twos old cheapies which everyone's seen before doping.

Don't know if we've done one of these before though, but you know you can't leave you up the old analog. Check it out. Ah, the specs on the back, but you, no doubt I'm thoroughly impressive and it's the Son brand trying to play off Seonhwa, which are, of course, the young, highly regarded Japanese manufacturer of analog meters. So yeah, that's just that's terrible.

Muriel Well, apparently these things cost one U.s. dollar and the other is sixty cents. Are you kidding me? Oh well. it won't take two minutes to teardown things.

We'll just open them and point and laugh. All right, let's play spot the error in the labeling Wow This has to be the world's best analog meter. Look at this point, five percent. look on the two hundred and all the Rangers and believing with a 1 mega ohm input impedance.

Brilliant. Hell, they get the 200 millivolt range out of that. It's magic. this should say.

Warning to avoid electric shock. Throw immediately in the bin. doesn't get any better than that. Oh Superb soldering job.

Oh, just just can't be beat. Look at this. How can is there any better multimeter than this? I haven't seen one, three and a half digit display. You say ok and don't you I Just hate it When these companies are rebrand.

it's just bloody HP all over again and land all over again was Sun Whoa now it's Sun ma I Guess they didn't want the electrons to fall out or do they with the M to the W Just a little rule of thumb, Beware: any multimeter that comes shrink-wrapped Luckily, the battery comes pre-installed Hey, no worries, all it needs is one of those 9-volt batteries as they promised in will get 800 percent more battery life out of this thing. Beauty that shots got memed written all over it. We've seen this exact model before, so yeah, no comment required. So thanks to everyone who sent something into today's mailbag.

If you liked it, please give it a big thumbs up. Catch you next time you.
