Hi welcome to everyone's favorite segment My ol' Bag when I open my mouth, let's get straight into it. Here we go: This one comes from Lyle Moffat he's from the old dot uk' is from Lisburn in the UK and let's check out what loyal is sent by the way I may as well folks and merchandise. if you like the warranty void if not remove sticker link is the merchandise link is always down below. I Get lots of people comment in hey where can I am you get the shirts from and it's like well the link is thing we think YouTube Description: oh this is pretty hard not coming apart Well bubble wrap great save your loves playing with bubble wrap.

So does daddy look at a note hi Dave oh I thought you should I'll send you some matched memory to fill out your video rendering machine through it which is still sitting down here I've just got to tidy up a few things in it. Um, because yes, I was I didn't fully populate all the memory slots. the four slots per or eight slots per processor or whatever such. apparently it's running not to its optimal thing that you'll see on machine.

Um, anyway, he's um, set 128 gig a memory. Awesome! Thank you Very much loyal. Um, they're all removed from a server. When they got 16 gig dims installed, he's included 20 in case any of them don't work.

Thank you very much. Geez, this is like a WoW that Oh box full of AC I Believe there. Um yeah the ECC server memory for those playing along at home. So there's the money shot for those who like their server memory.

ECC memory of course. Nice big heat spreaders on their heat sinks and they should a treat. Mmm Danya Next up: I'm gonna cheat on this one sorry, it's already out of the box and I think I toss the box out. Oops.

Anyway, it's too cool not to show you. so I will. If you haven't seen a Tada 3700 Euro 10k resistor in a box, it's a 10 K resistance transfer standard from a company I had never heard of before. Are we calm? They contacted me and said hey, we're getting into the calibration resistor business or if they weren't already anyway, this is their new 10k calibration resistor transfer standard resistance standards that they're still working on and they ship me one of the very first units.

So thank you very much. I'm all you know. Individually manufactured and assembled by nude virgins and calibrated with, you know, stroking the gray beard. Not at the same time, they're not graybeard nude virgins.

or they could be. Who knows. Anyway, um, there is German company. and yes, this is three thousand Seven hundred Euros I means about 5500 Australian dollars.

Ridiculously expensive. It's designed as a transfer resistance standard. Of course it is. Let's have a look.

it's got the exact value on the back. they had it calibrated at the German National Labs for me and it's got all the data here at the Kcb the German calibration facility anyway. I can scan all this stuff in I might link it down below. Reason I'm included in the mailbag is because I may not get around to it for a little bit.

So I just wanted to show you this puppy and unfortunately, it's not exactly 10k. but that doesn't matter. Of course it's Nine Point Nine Nine Nine nine, two, two eight. Okay, according to the case C B And yeah, it's got incredible specs.

It's got a manual and everything. They tested it at half degree C intervals and everything so fair. They actually got the real data on this. It's point One calibration uncertainty point 1 ppm temperature coefficient point 3 ppm per degree C I think mine's about 0.4 or something.

It didn't quite meet it. 1 ppm per year stability and yep, real schmack resistor. So I'm gonna use this to do as a transfer standard to transfer my resistor calibrator. You've seen it down here somewhere.

I'm gonna do a video on that. That's the plan anyway. and maybe I'll take it to a local cow lab and just see how close it is. A pretty good confidence it's got a real Schmidt custom Vishay resistor in here, one you just can't buy over off the shops.

Not like these. Bought one off the shelf, stuck in the box and then measured it and they sell it to you for $4,000 There's a lot more involved in this I Can't take it apart unfortunately, but they sent me lots of high res internal construction photos so you can see how they manufacture a 10k resistor in a box. There's a lot more art to it than you might think you know. The tellurium copper contacts and the anti thermal expansion stuff inside our board.

mounting construction inside low EMF wiring all that sort of jazz. So fantastic! Thanks guys! Really interesting. Hopefully do some neat videos for you Volk nuts out there soon. Next up one from Florida Hi to all my Floridian viewers.

hmm don't know. Anyway, I've everyone from Florida this one's from George Miss Kay's from St. Augustine in Florida Let's check out what he said. Oh, it says on here is electronic.

That's it. It's something electronic. Well, that's handy because the Eevblog stands for the Electronics Engineering Video blog. So apparently I'm supposed to have electronics on the show so we'll see with it.

set shall we saver? Evo Data Management pad software. No idea what that is set in. Sin. Oh no photos of Lithium primary Lithium battery packs but our Cr123 Lithium battery packs.

Interesting. a heart sign pad. something. let's have a look I suspect it's gonna be a tear now item and heart sign.

Something to do with a maybe some sort of heart monitor. Ah, this. Check it out. It's a it's a defibrillator.

Awesome defibrillator that'll make a great 10:00 a.m. to Tuesday That is definitely not a two-minute tear down defibrillator. It's a kind of a funny-looking one. Usually they're like, you know, they're not like round and funky like that.

It's almost hard shaped I Guess that was thereand was that their intention and the desire? You know, the marketing people said, oh, let's make it like heart-shaped shall we? And the engineers? Yeah, you got that. No, the volume just sucks. You know the volumetric efficiency inside that thing just sucks, but they kinda sorta got it looking like a heart. Fantastic now.

Has no batteries in it. but anyway, that will be really interesting. Defibrillator Awesome! Ah, George says the service life has expired, but it's fully functional. Heart Sign Sam 300 P Public Access Automated External Defibrillator Public Access 1r They put them in like a you know in where the average public can access it and then try and resuscitate.

So resuscitate? is that the word? Yeah, no I don't think, is it? I'm not sure I don't think so. Hmm. Anyway, um, he's removed the battery are two pics in close year. so they used that Cr123 soldered to you are there Ultrasone with the world? You know they're not budged together.

They've got a bit of our hot snot between them. all. Super professional. I've removed the battery.

The battery measured fourteen point eight, eight volts open circuit. Fourteen point one, five in 8. Ohms. It was a four amp little fuse micro fuse in series with the battery.

Anyway, please note the safety for safety. the manufacturer recommended not taking it apart. This unit can produce numerous pulses in excess of a thousand volts of a thousand abs. Beauty.

And here's the Samaritan Pad: The Good Samaritan If you decide to try and save some on the I don't know, a lot of people don't in the US. They'll get sued or something like that, won't they? Anyway, crazy. It shows you how to attach the things and only um, if needed. if advise to press the shock button.

So yeah, you don't want to go on. presumably it would lock it. If it detects a proper heart pulse, it would lock out. You wouldn't just accidentally press the button.

Surely, it would lock the damn thing out. And if necessary, begin the CPR You know, stand back, stand clear and this pulls out tonight like this. And there's your uh, there's your pads single use only. Of course your walk it out.

It's um, oh yeah, you got a yeah, it looks like you're gonna peel that off and there you go. Instructions on how that Yes, there were your instructions on how to do that. There you go for those playing along at home. If you ever see one of these and see somebody having a heart attack, instructions are pretty easy.

and I expiry date 2017. So it's you know it's still quite good. Now You might think that this is dangerous having the high voltage terminals right there exposed like that. While that's normally not supposed to be like this, George has ripped off the cover plate.

As you can see, there's normally a fixed cover plate. Every doubt. the batteries. This is where the primary Lithium batteries went, so it's completely harmless at the moment.

I'm sure it hasn't built up a charge or anything like that. So anyway, that normally doesn't come off. That's all. sort of.

you know, ultrasonically welded in. they're all glued or whatever. A little bit surprised that they use standard Phillips down in there to rip this thing apart. If you didn't want people to rip it apart, then why would you work that in there anyway? Um, it looks like it was my eating the old art.

by the looks of things. Hmm, there you go. That might make a very interesting teardown coming up. Thanks! George Next up: one from Matt Marion I think I'm pronouncing that correctly.

he's from Janet in KS Kansas isn't I Think right? All my viewers in KS The State Rock let's have a squeeze matters sentient. There we go Seven Note: let's be surprised shall we? Wow And it's yeah from must be from cancer yet you Newt Kansas Um, its local. It's a free twenty four point one five gig. Looks like some sort of Raider type gadget.

Yeah, that that looks very much like a Raider So that's yep. Yep, face for my yet here we go There we go: Radar unit the Eagle Plus Radar unit I Don't know if that was used by the cops, most probably. Anyway, that's mating chin Newt um Kansas So terrific stuff and as it turns out, way back in the early 2000s, Matt used to work at Custom Signals Inc Custom with a K that is I'm infinite Kansas making this. these are law enforcement radar detectors.

So yeah, a niche kind of thing. Um, he's not night I Think sure if this is working doesn't He's got some sort of cable I don't know if we can get it up and running and apparently it can be a K band or a Ka band am I'm not sure what the difference is I don't know my radar systems but yeah, now that tear down. Tuesday So there it is: Custom Signals Inc with a K Twenty 1.15 Gig that's somewhere in the K band and that might make in interesting teardown. and we've got the control unit as well.

and once again, all manufactured locally there. and Eagle Plus Lust calibrated in 2014. It looks like it was designed much much earlier than that. So there you go, like in the early 2000s when Matt worked there.

so we'll definitely have that for another teardown. Tuesday Thanks Matt Next up one from Nico Baumgartner is in from Zurich in Switzerland haven't been to Zurich awesome and I know you might know what this might be and this is a bit awkward. Let's have a look. thank you very much Nico it's gonna be awkward because I just remember he clued me up on this and way too generous guys.

like once again like 20 so thank you very much Nick Well fortunately two people said then sent in server module because they just toss these things out when they upgrade the service and don't like it as we saw before. They just upgraded to the 16 gig ones and they just toss out the 8 gig I'm stick. so these are these are 4 gig sticks. Are they any quicker? I'm not sure I'm gonna have to check the check the specs on them so whichever one is a quicker I assume that they both work anyway I do need to do, you need to check.

So thank you very much guys for setting in the server memory. I Don't know what I'm gonna do with the excess funds but no shortage of memory and embarrassed generosity of viewers never is to amaze me. Fantastic! Thanks guys! and there's the one Nico has sent here. Once again, they got the heat spreader on there.

they're a Samsung part. These are only four gig ones more than what I need. and people think you need a massive amount of memory for video rendering. for the video rendering I do eight gig total system memory is more than an average trust me.

I've monitored how much memory it uses when it renders and it's not a huge amount. it's all CPU processing so you know filling up the machine with even two gig sticks would you know have been overkill, Let alone four or eight that I've got here. Don't know which one to use, so thank you very much. Nico Most generous indeed to send these for people to send these memory modules and basically most of the stuff for my Xeon machine, the CPUs and the motherboard.

and now the memory is fantastic. Thank you very much guys! It will let me build up a quite decent video rendering machine. Next up, one from John Meeks thank you very much! John here some middle town in New York I'm Annie's from the Institute for pattern studies. interesting and she'll be right and vintage stuff haha Oh look look first.

Memes Engineers mini notebook for Rat Shack what's that one? Yeah, it's the So. we've got the basic semiconductor circuit, schematic, symbols, devices, packages, design and testing Wow communications projects. This is great stuff. Triple Five timer IC circuits so John got these as a kid and yet they've yellowed a bit with age as you'd expect.

um I think I remember recalls seeing these little ones but I ended up getting like the bigger ones I've shown before. but anyway, where these are awesome, they're still relevant today if you haven't listened to Forrest Mims he was on the AM pirate radio show so I'll link it in down below. it was an awesome interview with him. Awesome show and he's an absolute legend so definitely listen to that if you haven't And he heard me mentioned that Australia has a $1 coin? Yes we do.

We did away with our $1 notes I've got might have even been 20 years ago now. Um, I may be I Didn't know that USA also has a $1 coin. I did know that and he sent me one in. And for those who haven't seen the the Yankee $1.00 coin, there it is.

It's not the UM silver dollar, this is just the regular $1.00 coin. and I remember getting these in the US and I remember trying to buy something with a dollar coin. They said oh, we don't accept those, we only accept the dollar notes or whatever and just I don't know what the deal is there anyway. So yeah, he says like people prefer to use the one dollar and Bill and so these things just really circulate.

You can't actually go into the bank and ask, take it one So there you go, $1.00 coin. Awesome! And there we go. We have ourselves a Yankee one dollar coin and an Aussie one dollar coin with the kangaroo on the front. Although we do often have like a you know special series, these pop up all the time with different things.

This was that's a famous dancing man, our photo and that's to commemorate the end of World War Two, and on the back side, there you guys have got George Washington. We've got Her Majesty on the back of course. Queen Elizabeth is like yeah, like 2,000 years old or something. now.

yeah the Aussie one's a little bit smaller and it's thicker. There you go. there's a comparison and the ridges around the outside on the Australian one. Of course they're for the blind people who cannot feel the coins and the Yanks have got Liberty on the outside.

Look at that and I Was gonna say that there was no in god we trust' on this thing, but unfortunately, oh there is. You Yanked her unbeliev. We'll really come up with one of the first secular democracies in the world to have separation of church and state. Brilliant.

And then you just throw it all the way in the mid-50s and put In God We Trust on your currency and put it under God in your pledge of allegiance. Oh Lievable. Looks like you might have your first female president coming up. By the way, when Clinton yet another Clinton But yeah, there'll be a there's being a black president.

There'll be a female president. There'll be a gay president. before there'll be a bloody atheist president. Let me tell you.

And last but not least, one from Greece I Don't want my Greek viewers. um, some nice-looking now what's looking stairs on there I Don't show stamps very much these days, but look at those. Do love looking at stamps. Very nice and it's clearly safe t-shirt because it's from NT NT t as in t ee t ee So let's have a look back I thought it was I thought it was like a Decker look at this back in time I Love it.

Whoa! BT ZF T shirt in the Acadec Oh that's the Acadec. your type you know font and everything is not fantastic. sorry Sent magnetic antigravity. The future is now.

Look, it's got the MagTek Power Laces shoes. Awesome! thank you very much Mike Oh Mike Oh - Mike Oh he's from mum MTT comm Olin Come in down below. so yes, they ran in TT dot-com There's two of them hi guys and they designed their own t-shirts and sell a unique t-shirt design every 72 hours so you can't get them anywhere else. So fantastic! Ah love it.

This one is particularly sexy. Oh yeah, that rocks. The strands can appreciate that. And the mag shoes I Like they bought these out and in a limited run.

Not the shirt but the the real shoes and they went for like a couple of grand or something like that. Anyway, it is 2015 Beauty. hopefully. I'm gonna arrange something when the particular date comes.

That's the plan anyway. I love that old-school cassettes that there you go NTT And yes they do ship worldwide. Awesome unique custom t-shirts Love them! Next up we have a Phoenix Huge! Always excited for Phoenix which it pretty much means like it's a commercial and in this case it's from Silicon Labs In its from their Norway yeah, it comes from in Norway hey, quarters, are they based in Norway I'm not entirely sure. Anyway, we're doing.

let's open the damn thing Alright, so we've obviously got some sort of Silicon Labs starter kit or something like that, so let's check it out. We always like starter kits and things like that here because it I know I don't often get around to playing with them. Hopefully that's gonna change with that. Dave - who's here to help out a few days a week? It's not here today.

so oh jeez, Development Tools, it's gonna be squeezed. It's the Sleepy Babe so you look sleepy I'm not sure. Anyway, it's the Sleepy Be development kit. Oh no, what, we've got one sleepy.

We've got one busy and we've got one Universal huh? Here we go: Three different products: the Sleepy Be starter kit, the universal be started hit and the busy be started hit. And here's the Universal B starter kit. This might be familiar to you if you see my previous videos on the gecko starter kits because well, Silicon Labs Of course bought the Gecko. So the EFM eight series processor is the original.

You know a Gecko tiny gecko that was seen before. Nice sharp memory LCD on here but looks about real ultra-low power things these asked Universal interface which they used for a lot of their expansion boards and things like that. you've seen an expansion board I've used before they had a sharp memory LCD did a clock and things like that so this is their universal one and then us debug headers and things like that. Let's plug a battery in and yep, here we go.

You can power from AEM no no that is USB or battery. let's turn it. Hey, check it out, check it out. There we go.

Space Invaders Oh Awesome! This is great! What an awesome demo! I Like it and presumably they've got like all the source code and everything for that for driving the graphics on this sharp memory LCD and the whole, the whole works so that's pretty impressive. Hey fantastic. leveled up. Check out the resolution on that shop memory.

LCD Very nice indeed. Um, you don't get any thing else with it apart from USB cables like no documentation. No CD nothing but you do get yourself a battery. guys have one sitting around and a couple of USB cables.

a mini and a micro actually. So they've got a USB mini over here for the debug and a micro over here. Maybe it's a USB host or something like that, perhaps. Anyway, tiny little package there for the EF M8.

What is it? The 8 you be won by looks of it and of course little a joystick thing here. Fantastic. That's a nice little starter kit and this is the Sleepy B starter kit. Almost identical.

if I put them over like that, you can't see much difference apart from the fact that it's got a capacitive touch sensor like I'm old school rotary one. by old school I mean like you know the original one iPod capacity of Art Control It's got a 32 kilohertz watch crystal there. By the looks of it, it's got another chip up here. Is that maybe some Si 702 one? Hmm.

I Just had to check that that is a humidity and temperature sensor. nice. And they've actually got different processes in here targeted for different uses. hence the different demo boards we've got here.

No doubt the universe will be up. Here is the 8u B1 and the sleepy is 8s one you I'm gonna presume stands for USB Hence it's got that USB host there by looks of it and s, well, it's sleepy. It doesn't have the Us B stuff, but certainly. Well, this one probably has a real-time clock in it, but it's not connected anyway.

Maybe it's designed for lower power applications with the touch with the capacity of our touch sensor interface building. Anyway, let's power this one up. the Sleepy B And yet there you go. Same clock application that we had before.

By the looks of it, Does it do anything else? No, it probably just goes into different sleep modes and things like that. just designed a demo for. really. you know, if you're developing ultra low power applications, you're going to get this demo board.

if you want something with you know, more powerful USB Host interface if your parents something else, well the other chips probably they go and then we can go from the sleepy be to the Busy Bee. look at this. I'm significantly different package here. There we go.

We've none of this Qfn rubbish. that's yeah. I'm real difficult to do down here. What's that? a point five millimeter pitch Qfn.

Even so, this is a bit better. What's that point? It's not point fights. probably 0.65 millimeter pitch regular. A more accessible package.

easier to solder anyway than the other one, but this one's got the Busy Bee I Don't know. Is it just more powerful? I Have to check the specs it's got no. USB It's got no touch. It's got no temperature sensor nothing.

Oh Using my micro rule a pin pitch guide there, it looks like that's about yeah. it'd be easier if they had the chip. D Sold and put it on there. It looks like it's a point six five mil pin pitch.

Definitely not point. five millimeters to power it up and see what we get. Oh it's space invaders again. lot of yell and I was a little bit off on the gecko thing.

They the geckos we've seen before were the Efm32 S. This is the EF m8. This is the these are the 8-bit EF M series micros and the micros are actually called the busy be the universal B and the Sleepy Bears not just the name for these kids. these are what the three processes Accord and yes they're a bit micros.

our 805 one core and yeah, these other three different types have got different functionality. the Busy Bee for example yet nothing fancy. No way USB No fancy touch stuff. but it does have our three Pwm modules.

All of them have 12 bit ADC in them. Very nice indeed. All are low-power 150 micro amps per megahertz. Power consumption pretty good.

And listen, one micro app on the sleepy. be here or there other ones like this but this is the only one that has that touch. If you want that building, you have to get the Sleepy B chip. Lesson one: Microwave current consumption.

Wake on touch so this thing can sit here and you know sit, wait, and power up until you do the touch. Nice! There's one thing on here that I don't see and that is a jumper to measure the chips supply current because we know that's everything on a development kit like this. you want to be able to measure the dam supply current noise, our silkscreen labeling for the pin outs on there. but yeah, where is it I can't see it ground and battery terminals there.

but please give me a nice big to pin header on there in series with the supply of this chip. So I can get a micro carrot or some other tool in there to measure the sleep current on this thing. Ah, file, check it out. Quite a few bare die flip chip packages in there.

Hmm I wonder if we can flash them? Let's see if they're photosensitive. Sherry I've got my xenon flash here and as we saw with the Raspberry Pi 2, let's let's have a go. Nope. still works.

Oh come on. Whoa. No, no problems whatsoever. Not photosensitive.

haha. Can't even stop Space invaders. So these things do have to compete in a crowded 8-bit microcontroller space. but 150 micrograms per megahertz power consumption? If your key system requirement is low-power and you don't need like 32-bit arm, then they're probably worth looking at.

And these things are very nicely priced. 30 bucks a pop for each one of them available from Digi-key Mouser Arrow and direct from our Silicon Labs as well all the usual suspects. That's pretty good value for a little dev board like this. Although, as always with all these microcontroller development boards, all comes down to how good the the software, the development interface, the debugger, all that sort of thing is.

it's got a Sega debug ability and presumably you get some sort of Sega debug functionality for free. But some of the high-end debugger stuff from my Sega is quite expensive. But it's very, very good though. So um yeah, it's a bit crowded the 8-bit marketplace, but yeah, these are little 8:05 ones.

Every man. this dog does like an 805 one like type chip and they're you know well do you choose your pick your Atmel do you choose something else? one of these I Don't know. You could debate the various options until the oh I'm um, hopeless here debate the various just missed various options until the cows come home, but I've leveled up. This one might be lucky.

last. we've got one from Maxim so let's check it out. What are we go? Max 11300 Okay, it's a starter kit is it? Oh yes I think I might have. they may have emailed me I'm sorry I get so many bloody emails and stuff so thank you for choosing Maxim Integrated well.

Thank you for sending it to me I didn't cheat I didn't choose them, you sent them to me. Of course we all have a love-hate relationship. I'll add some USB cable I'll have a love/hate relationship with Maxim and they've sent a couple of little boys. Interesting.

let's check them out. Now it turns out this is a rather interesting beast. Comes as our the main development board here and I got this one separately as well and this is like a serial USB programming interface with an FTDI chip to actually play around with this DAC / ADC chip and it's absolutely fascinating. Device: the max 11300 I'll put the datasheet link down below.

Definitely check it out! So this is just a demo universal demo board for it. What it is is a combined and 12 bit ADC and 12 bit DAC up to 20 channels of ADC 20 channels are Dax. But but the interesting thing is that each pin which is available on these pin headers here can be configured as either a DAC output, a buffered DAC output with like 25 milli amps current capability or an ADC input. Both of them are 12 bits I'm not sure the absolute are performing to have a look at the details.

got to build in 2.5 volt voltage reference 0.25 percent absolute 10 ppm typical 25 ppm max drift on the thing. not too bad 400 K samples per second. Reasonably quick for a 12 bit converter so you know as far as as linearity and you know all that sort of jazz I don't know I Haven't looked deeply into the details but choose to have all that flexibility in the one chip. Really really interesting.

It's got a zero to ten volt input rain so single ended input range. You can do bipolar like minus 5 to plus 5 or it can do a direct a DC input of 0 to 2 point 5 volts bypassing any internal ampler own internal attenuate in 10 you aters. sorry for doing that. So direct a DC input.

Very useful little beast and it's all configure where you can play with it and without you know having to actually wire it into your design. you can just send you know it's send commands down and and drive the thing from your PC So well, was checking out its out 15 bucks one off a cost. It's not a cheap chip, you wouldn't expect it for this sort of performance. and Maxima are not the cheapest chips on the market to begin with, but they're usually quite decent arm performance $6 in quantity from the likes of Digi-key and mouse and things like that.

So and it does start to come down a bit. that was our 500 volume on there abouts. But like, it's well worth considering this if you've got. So if indeed, some sort of flexible ADC DAC arrangement in your product, that's a neat chip.

you.
