Hi welcome to everyone's favorite segment. Mailbag where well you guys send me stuff and well I open it. Live on camera here. Live here we go.

Um, we've got a big one local this time from an Australian it comes from Cindy Baker um is this a girl? perhaps? um I don't know I don't want to presume but uh, thank you very much Cindy it comes from Barisford and um yeah, it's in a PlayStation 3 box but uh hm. not quite sure it's a PlayStation 3. if it is, it's in pieces and I'm not sure what I would do with it. but anyway, here we go.

Let's open it, crack it open and see what we get. Most likely the box has just been renewed. It's heavy. It weighs about 6 kilos so uh, could be anything.

Oh um no, it is it a PlayStation I don't know I don't have a PlayStation It looks like some sort of video game. It is a Playstation 3 taada. Look at that. Why has Cindy sent me a PlayStation 3 I wonder I've got no idea.

um there's no note inside. Oh thank you very much Cindy I presume it is broken but I've never uh used well it look it looks I don't know. Oh here we go. It's some sort of uh uh, the gamer uh, nerds will be uh screaming at me cuz I don't know what this sort of uh stuff is I've never used a PlayStation 3 I'm more of an Xbox uh kind of guy.

Damn that's heavy and it sits on some sort of dock which is some Power Wave It looks like it's got some. no fans there we go I don't know what that does, but uh, it's a Power Wave It's like it. It's obviously not, uh, standard. it's just some sort of third, uh, party, aftermarket thing.

but we have ourselves a PlayStation 3. Presumably it doesn't work and Cindy wants me to fix it, but uh, well. I don't know. There's no note inside.

If you're going to send me stuff, at least include a note. Wow. Check out the HDMI and the ethernet connector on the back. They have seen better days.

Look at that. H corroded to the hill and the correct technical term for that is crusty now. I can only presume that it's not working and Cindy wants me to do a tear down of it. but I'm not quite sure.

Um, why? uh, because there's like there's got to be I haven't looked, but there's got to be surely a million PlayStation 3 tear Downs on YouTube All the uh, gamer nerds have surely torn this thing down. Anyway, let's power it up and uh, not sure what it's supposed to do. It's supposed to go beepy beep beep. Oh, we got a red lead there.

What does that mean? Nope, nothing. I assume that's a touch switch once again. yeah, sorry. I've never actually used a PlayStation 3 and uh, people are going well.

you never played a PlayStation 3 No. I've hey green, yellow, green, yellow and then flashing red. Anyone know what that means? I'm going to have to Google that up. Maybe it's a, um, a classic fault I don't know.

Well, I had a very quick Google and uh, this. uh, three beeps and flashing red lead. um seems to be according to one report, some sort of overheat. uh issue something like that I don't know.

Some people say they get it when it's ejected or something. I don't know. I'm sure I'll have a whole bunch of people. uh, tell me different in the comments.

so I I don't know what I'm supposed to do with this thing. uh Cindy please let me know um, what I'm supposed to do if you want me to do a tear down like I said, there's probably a million of them already on. YouTube So I don't think there's much value to be G there fixing it h I don't know. There's probably hundred million different web pages and videos devoted to that as well.

so thanks for sending that in. Cindy But I don't think we're going to do anything with it on the mailbag here. Really, it take me quite some time to do any sort of extensive tear down or repair. so uh, please let me know.

and uh, this one will go on the shelf for a future video. And I know there's a lot of people who don't like Po post cards. but I got four of them here and I won't read them out. but rest assured I have read them I'll just, uh, quickly display them Greetings from Bhan I'm pretty sure we've never had anyone from Bhutan before.

thank you very much Jared Gerard if I'm pronouncing that correctly and I'm not even going to pronounce that one, but it's uh, rimit labor I'm sure I've got it wrong. sorry, Absolutely hopeless. Looks like a hacker space complete with beer by the looks of it. fantastic.

and so someone doing some work down there. so thank you very much Felicitous who's at Felicitous and at Part Keeper on Twitter and it is a hacker space. There we go and there's the address. Check them out in Germany Hi to all my German viewers and we have one from Roads in Tada Here it is, um, he's Swedish but it comes from Roads in Greece Thank you very much Dri.

Oh very nice and we have a threedimensional postcard look at that, they're the Redwoods Well, it's kind of. you know, it's embossed kind of thing. Very nice. The Redwoods fantastic from Dave thank you very much Dave And we have a good oldfashioned letter here that's where to send the stuff.

By the way, from Paul in Doncaster in Victoria So let's whip this one open. see what we've got in here? It's a little bit. oh, could it? Is it over the 5 mm limit? I Don't know. I Don't think a straight post gives a toss but uh, let's have a look.

We have a letter and we have some little oh little adapter boards. Nice! We have ourselves what looks like some pretty Schmick opamps the Lme 49088 that's .88 nanovolts per Roots HT Hertz uh noise. so awesomely low noise and uh, they're little oh yeah. so to dip adapter boards, they're always very handy thank you very much.

but uh yes, he's obviously um, obviously about the uh noise stuff that I've been dealing with in the uh previous videos with the uh DSA and yep, there we go. Um, he was interested in the effort to upgrade the 356a which uh, double 60a which I may need to do because my latest one I don't think I'm going to be able to repair the sucker. Anyway, please find theou 6 Lme 490 opamps. These chips have very low voltage noise 88 n volts per root herdz.

Absolutely incredible. outperforming the 797 which is I think one of the ones that I um you know, just sort of the Jelly Bean well not Jelly Bean but sort of. You know, the industry standard low noise uh, industry opamp while being a much less costly IC current noise is higher so this Op provides benefit for low Source resistances only and SMD only packages hence the adapters. Awesome! He's been gathering information on ultra low noise amplifiers.

Linear systems make a number of low noise jfets Analog Devices and that core produced lonely, um, costly, low noise BJT Match arrays o Very nice and simple to see how you go modifying your DSA thank you very much Paul Awesome! So yes, I will get uh back on to Uh, possibly upgrading that Uh amp after I get done with the Um, hopefully well attempting a few more repair videos on the uh, uh, more Upm Market DSO the Uh 3567 a dynamic signal analyzer. but uh yeah, there's no way my analyzer can actually measure the performance of this sucker. But this would certainly be um, the best choice if I was most likely. um, all things considered, the best choice for upgrading the Uh front end amplifier on that thing.

Warning: Will Robinson Audio file: Wank Alert Lme 49 Z Overture Oh yes, cuz it's going to sound fantastic. We're playing the William Tell Over sure. ultra low Distortion Ultra low noise operational amplifier and uh, there's some of the applications. Oh fantastic.

Ultra high quality audio signal processing blah blah blah. Input Current Noise density a nominal Uh Banner speec on the front page. Never believe it, of course. .9 nanovolts per root Herz Typical 1.3 nanovolts per root Herz maximum.

And if we actually go into the curves here, it's actually not hugely better than the LM Um, 79, Uh, seven, Uh yeah, 797. And if we have a look at the voltage noise density figure here, yeah, there's the 88 NTS per root Herz Typical, say at the 1 khz uh figure there and just starts to roll up the one on F noise of course. and uh, there we go down at Uh 1 Hertz There we're at. oh you know one? two almost 3 2.8 say nanov volts per rout Hertz If we compare that with the Ad7 97, it's actually around about nominally .9 NT per root Herz So basically the same, it's just a rounding error.

Uh, really. these Analog Devices are bit tight asses. They're only going down to Uh 10 HZ here on their Uh graph. That's not very like somebody's just drawn that with a pencil.

That's not like a real plot. You know this looks like a real plot that they've actually made. This looks like something someone's just drawn that in Photoshop or something I don't know in bloody paint or something. Ah, crazy.

Anyway, only goes down to 10 Herz and it's like you know 1 uh, say 8 uh Nan volts per root Hertz there at 10 Hertz And well say at 10 htz here, 1.5 you know? Well, it's they've got a logarithmic uh scale here on the uh vertical. So yeah, you know it. It's not huge amount better, but it's actually worse in the current noise density here. If you check this out, it's normally 2.8 Pico amps uh per root Hertz and this one is down under two.

There you go at around about that 1 khz figure where it starts to uh ramp up and uh yeah, this one is a bit better, but it's actually higher. um at the higher frequencies. So there you go, not at the higher bandwidth? uh sorry so you know, not that great Once again, specified at plusus uh 30 volts only with a uh Center rail uh, common mode voltage there. so current noise density I'm probably I was going to do like a follow-up video to my previous Noise video but it didn't say uh, talking about the current noise density and going through some calculations and uh, stuff like that for a typical circuit, but it didn't seem very popular.

that video, you know I thought it was, you know, quite good and um, yeah, it wasn't that popular. So I don't know whether or not I'll bother with a follow-up for that one. but uh yeah, this one. I Think the primary thing is, there's probably not a huge amount of difference when you ment both of these chips in a practical uh circuit.

Probably not a huge amount of difference between the two. You'd have to go into uh, finer details and probably do some real in circuit performance measurements. but uh, as Paul said I think this one is significantly cheaper than the 8797 which oh man got to sell your right leg for. Next up is from Charlie Pia thank you very much Charlie the name rings the bell.

Has he sent someone something in before? Perhaps. Anyway, he's from Uruguay Whoa, we don't get too many from. UR U Check out the Urugin stamps. Very good and he sent it to Sir David L Jones Call me sir God damn it.

name the movie. Anyway, let's have a look. um sorry it is actually already opened. um that's because uh it looks like um Australia Post uh Customs have inspected they so a dodgey we're getting too many.

You know this sounds sus with sir on it. You know that obviously uh raised the red flags there but uh thank you very much Charlie let's have a look at a whole bunch of stuff. We got a oh a calculator Canon checkbook calculator I'm not into checkbook calculators but am into scientific calculators will pop that off. We'll just find a single uh chip on board.

one that'll probably be a PC based based on the that form factor, it'll be a single uh PCB chip on board. uh blobbed perhaps. Anyway, um let's hey woohoo it is a DeLorean Fantastic Thank you very much. Charlie Sean Will love the DeLorean Hot Wheels We have a board.

no idea what that is. what do we got here? We got infrared lead photo transistor by the looks of it and we' got ourselves a some sort of NEC part. no idea, some memory coupled to that and another big NEC with York C on it. No idea.

uh obviously a big LCD designed to go on there. not sure what that uh, that's probably our keypad. so we got LCD keypad. so um, and a battery terminal.

some some sort of handheld uh PDA type thing going on here I guess I should read the note, shouldn't I And there we go. That's probably for the uh, um, internal speaker although that's the height of that isn't nearly matched to that. Anyway, we got a watch crystal there and yeah, anyway, that' be my guess is some sort of uh, you know, um early Palm sort of uh PDA type device. Oh, here we go Australian Government Australian customers and Border Protection Service We're very serious here folks about inspecting things with sir on the front of them.

oh no items have been removed by customers and Border prodection Australia Post as blah blah blah opened it and put the rubber glove on blah blah blah sing the damn Support Center H Give me a break the first day of October of the Year 2013 nobody starts their letters with that anymore I Like it Sun new episodes still have to watch. Love them! A weird calculator for your collection. thank you very much a toy for San he will love it the guts. Oh a HP 48 SX There you go.

Ah calculator should have known. Jeez bit of a calculator should have known that. Maybe it's nice to see te technology and construction quality. I think this one is from latest batch because as far as I know the processor does not correspond to the sline.

the following: um see I didn't you know it's just got NEC on there? Um, they fabbed the chips for uh HP have they so I wouldn't have guessed that's a 48? um SX I don't think I've ever taken apart a 48 SX HP calculator before and that doesn't Oh yeah, there it is I missed it. There you go. HP there you go. should have got that and there you go.

Yes, it still used the old uh satin um architecture processor. so if uh, people haven't seen the 4bit architecture processor inside these um well early to you know, mid a fairly late model um HP uh process. Not sure if they're still using the satin are they I think they are in a couple of Cs I personally have the GX model which I still used. Recently acquired the 15c, the original version.

awesome thank you very much Charlie Yeah so there you go: NC have obviously fabbed the satin processor for uh well, a couple of Uh chips here for HP and uh, that's inside E48 SX Calculator absolute classic and there's the old school HP logo. look at that and then it became agilant although the HP calculator division stayed with HP cuz it was a Computing device and well, Agilent's gone the way of the dodo. Now we're going to end up with a new bloody logo and God took me like 13 years is to get used to the old one. Unbelievable now.

I did mention this: Uh, checkbook calculator is probably uh, just a single board with chip on board. I'm going to have to. Yeah, there we go. Yeah, there it is.

CR 2032 battery. Don't know why it didn't work then and uh yeah, it didn't work. Um on there you go. Got to press the on button? There you go.

Checkbook: I Have no interest. oh sorry, didn't zoom out Checkbook: I Have no interest in money and stuff like that. but there you go. Canon checkbook calculator could be a rare one.

who knows. I'd have to look it up so uh I don't want to destroy it I do have a calculator collection and we're going to have to flip this bloody thing open, take out all the screws because well, just got a ground plane on the back and that's it. and no. I have no idea why they would put the crosses on the back of this thing and uh, so the keys are all going to fall out and oh no, it's not a chip on board there.

Yeah, got there, you go. Um yeah. even older than that, it's a a squished, uh quad flat pack. one of those, um, you know, lead.

Um, not the regular uh J lead uh type, but just the uh uh ones coming straight out. I can't remember offand uh, the name for that. but there you go. They've actually got that look.

Check it out out. They've got some extra traces jumping across here like jumper links. They've put them on there. They've got their double-sided board, but they haven't actually used it.

Look at that, they've applied. You can see if you get the correct angle of the light. Yeah, there we go. You can see that they've taped they've you know, adhesed that on as a separate step afterwards.

Look at that. Jeez, you don't see that very often. Check out the in on those surface mount caps that is crusty as unbelievable and uh, and surrounding the chip, there isn't any better. Look at those couple of Chip resistors and Chip caps there.

Oh awful. We have ourselves a Japanese Epson LCD display there and well, yeah, there's not much else in it. Um, these things are always, you know, very simplistic custom. Uh Asic manufactured by NEC but yeah, that looks like a fiducial there.

I Don't even know why they need a Bloody fiducial on this thing. I Not even sure I mean machine assembled my ass. You can really see that extra layer just stuck on top there. You can see that it's like a like a taped uh sort of film that they would have manually.

uh, presumably someone would have manually pressed in place. I'm not sure of the exact manufacturing process, but that would have been a be pad um down there coming from from this layer. here. look at all that just garbage, all that crud on there man is that is that like so they like is that solder? I mean that's just awful.

They adhesive type jump link so somebody knows the name for this old uh uh technology of the stick on um you know, tapes on top of the existing board. Obviously they're lying on the shoulder mask underneath so it doesn't uh short out and you can see they've got a test connector on the side of this board which would have been used for production testing no doubt. Well, they say they don't make them like they used to and well I'm glad. uh hello.

McFly Next up is Mark Nas Nas however you pronounce it sorry Mark Um, he's he's a Pom. he's from the UK from greater Manchester to be precise, Be in there and we have a t-shirt I Love t-shirts All right let's have a look see what we get. It's a lucky dip from friendly factories. organic cotton.

What? Oh it's the Sun shirt. Yes. Oh fantastic yes thank you very much. Um yeah.

Mark I Think on the Forum Um, went to well actually a whole bunch. Well I don't know about a whole bunch, but uh, you know quite a few of the Um evev blog art. Forum Guys went to an open day at the Uh CERN They had a great time. Apparently they all met up there and had a whale of time and they uh Mark said he'd get me a T-shirt and he did.

Oh awesome and oh postcard and that is a is that a one of those uh 3D things? no I don't think so. It's just nice and shiny. but look at that porn. Unbelievable! Who needs a religion when you got this and it fits perfectly.

What a brilliant t-shirt Large hron collider. wish I could have been there I'm so jealous. Ah what is it like 50 bucks fly from the UK over there to uh, check it out. Bit more expensive here to get there from here I wish it could have been there guys but thank you very much Mark for the T-shirt brilliant and we have ourselves another Pom n Kingsley Lewis thank you very much n from Uh Norfolk in England Haven't been to Norfolk and we've got ourselves an E-reader and no battery something battery.

Anyway, Let's uh, check it out and comes in a little pouch. Oh look all right. Oh there you go, He reader who something happened to it? This is going to have to be a tear down folks. Is there a letter in here? Let's have a read read.

Get it no pun intended. Two United States dollar bills a one and a F. Thank you very much. Absolutely love the show and Forum in fact it has become one of addiction.

A Don't blame me I'm sending you the Sony E reader for tear down. It's probably not worth fixing. The screen has gone wrong yet and so has the power supply. Oh yeah, that's just some sort of like, uh, you know there's some sort of row and column thing gone wrong there so that's rather interesting.

uh, fire mode. So anyway, um, off hand? uh I don't know. Is it the driver chip is just internal connection or something like that? No, it's got to be a driver because it's fed uh, data and of course the data on these uh, just uh sticks there and uh, you know it doesn't need any power to uh, keep it going and uh, for these eink displays, it never worked correctly from you. There you go and had to return the not charge recognized by the computer.

so managed uh to get it charged and sort of work but never got used and the screen went wrong. Oh yeah, the battery was registered only 4 volts unit was saying no battery during the hard reset. What a crap. I Also found this dollar bill and $5 bill of 2003 V say that may work in your bill reader.

Ah cool, thank you very much. Nigel Kingsley Lewis and that one will go onto my tear down bench. Yes! I Do have a tear down bench. Where are some tear down items sit? As you can see, there's not many, at least not big ones.

Anyway, there is no way I am getting that name wrong Kettle I'll pronounce that as a silet j sorry I've got it wrong. Hi to Mar Art Norwegian viewers so let's check this out. It's uh, some. Electronic Component Very slim in an envelope so not very big at all.

Oh look oldfashioned typed oh I Love this folks. Look at this oldfashioned typewriter letter. I Haven't received one of these in forever since before the internet when I used to get uh mail actual mail with a um stamped. Oh sometimes if that were nice, they send me a stamped self addressed envelope and I'd reply and I'd get my typewriter out.

Yes, I actually had a typewriter back in Oh gee, I don't know the 80s and uh I would type these things out and uh, jeez, those were the days. Anyway, Um, here is a match of pair of matched analog repair parts for fluke. multimeters are found were tied in up in the old Parts being at your Electronics club soon hacker space at the T mark University uh College in I won't even pronounce that in uh Norway We don't have any flukes here, so we thought we'd ship it to you to see as you seem to have all of them. No I don't have all flukes I'm not a collector, please excuse the Caps This letter is written on our old Telly type 33 TDI from the' 70s.

Oh brilliant. It only has uppercase asy attached to the punch card reader ribbon which can be fed into your teletype to produce a copy of the letter. Oh oh man. old school points.

Definitely attached is also a Swedish Crona a nice modern Norwegian one Crona coin with Viking symbols. thank you very much Brilliant! Kettle I'll pronounce that this a Norwegian coin. it's got a in it. Got to save some cost.

Brilliant! There you go: 2,000 and one Crone one croner is it pronounced Crona I Guess it is and this is just fantastic. Here's the paper tape which actually contains the text for this letter that they fed into it to print the letter out. Oh I Tell you what, That is just gold that cannot be beaten. You guys get the Uh, get the points for the best EV blog mail bag letter ever.

Can anybody top that? And here's our fluke: Parts Checking out U3 Analog IC I wonder what? Uh Fluke meter? it's at 1976 10 months 76. Absolutely brilliant from the parts department. Oh this is just gold. This is like all original I don't even want to open it.

Oh but I have to I have to I've got an old uh, presumably like from a uh maybe a oh no 70s uh series? no 76, no we it' be from like the 80 oh 8020 or something like that and uh oh there we go. Ah classic. totally old school dip package. So Kettle didn't say what Fluke meter this was from.

This is a 1981 vintage or really recent stuff. s52 SC who actually made that off hand? I don't know I'm sure somebody will be able to, uh, tell us. Oh, hang on. Oh no.

I thought that was uh, thought that was is that used? No, it's just no. look, it's been. It's had some format like that. Ah yeah, our foam is just fall into bits and uh, all we're left with is, uh, some crusty pins there.

It's still going to be usable of course. but yeah, that hasn't uh. survived the test time. That old conductive foam, that's for sure.

I think the oldest fluke I've got in my collection here is relatively modern Series 2 meter and of course, uh, this has still got the uh, old school uh Construction in it with the uh fluke Asic the surface mount Asic on the bottom. There you go. It's had its ass blown out of that input protection resistor there. but uh, yeah, just the two fluke SMD as6.

So if anyone knows, uh, what this particular fluke part number is, it just says u3 for that analog uh set part number. There we go. Matched analog set is a subject to destruction by discharge by static electricity. Yeah, be careful.

it's okay. Got an any static? M and I'm not using my wrist strap. Oh no, it's gone anyway. If anyone knows what fluk meter that's from, um, it's obviously you know.

Uh', 70s, uh 1970s vintage. This mail bag is getting a bit long I I think lucky last from Christopher sturs from Vinton in IIA Iido no Indiana do Iowa sorry I don't get much M or send much mail over the years to Iowa sorry to all my viewers in Iowa Anyway, we got electronic components quantity free and a robotic toy insect. Oh robotic toy insect. Oh my goodness Oh my goodness.

I Can't wait and once again, it's going to be a kit probably. so forgive me for not being able to assemble this today. but it is. Oh there you go.

It's 6:21 p.m. I've got to get home. the wife will get most upset. read first I've got to read it first.

reading from the corn fields of: Iowa Yeah, that's probably why I don't get much mail from Iowa it's just all corn field I Must confess to having very little hands-on experience when it comes to e beond most basic of concept but I still greatly enjoy your videos F Fascinating, thank you I've had an interesting Electronics from he is currently department manager at the local Radio Shack Awesome! A national retailer that used to be the place for electronics hobbyists. Yes, um it wasn't called Radio Shack here in Australia Of course it was called uh Tandy Tandy Electronics was the name here? And yes, you could walk into your Tandy store and you could buy your you know your Uh 4011 C M chip in a little cardboard packet and you could buy you know two resistors for a dollar in a packet. You know they had all the different packets of all the different values and you'd buy two of them. Fantastic! It's still an interesting job.

Excellent! One of the items we sell is called Magic Jack very basic Viip adapter. Not surprising it doesn't work very well. I Figured send a couple of different models that we had for tear down or burn open open fire which if you feel more appropriate. Did I mention these don't work very well? Yes you did.

Probably the only good thing is that there is a hack that lets you use the silver. Magic Jack with Google Voice It works quite well. unfortunately. program runs it, run, that runs it costs money.

a boo. Finally, I Thought you sent along a couple of Hexbug Nanos for Sean and you to play with. For such a simple design, they're incredibly fun. They work on a hard surface is rubber ESD mading a hard surface, it's good enough.

Thanks again for your awesome videos. Have a good day! although if if it requires, thank you very much. Christopher um if it requires like a hard surface I mean under here I've got my uh my Pine uh bench top. Of course that may not be hard enough.

You may need like a laminated uh uh bench or something like that. I found when I was doing the battery uh drop videos for example that yeah, the rubber just doesn't cut it it. uh it absorbs a lot of stuff. but anyway.

um these are only little insects. Oh look at these. look at these. Magic Jack there you go.

I will uh, check those out I have to yeah, tear down I can see through there. Gee, that's just it's just Metalized plastic. It's just yeah yeah. makes your skin cruel.

It really does. and uh, we've got ourselves a cheap ass uh USB adapter Yankee plug of course and a magic jack. plus I will check out those. What I'm really interested in is these rather large suppository packaging.

Is that the official name of it? the Hexbug code inside register and play online. Oh look at them. it's like a like a a bristlebot um kind of thing. I guess I got to cut these suckers open.

is's this one here? This one's already been opened. Here we go. It's like a bristle bug. Oh these will be fantastic Sean will love these.

Yeah yeah so they just yeah. look at them. they're so cute. Look at that.

a fantastic. that's just brilliant. They' they've gone to they've gone to town that that looks fantastic Sean will think this is is the best thing ever although he's about to go to sleep. so I better get home in a hurry.

but uh there you go. let's turn it on. Oh vibrates There we go. Oh, it's off.

Holy crap, it's off. Holy crap. Hang on. Holy crap.

It's off. It's off. It's off. It's off.

Will it go off the bench? No, it's stuck. It's stuck. Woohoo who? And it's off. It's doing circles.

There's my bare feet, folks. It's Look at that. it's doing Circle work on the carpet. Brilliant.

And of course there's not. These aren't worth, uh, tearing down cuz there's nothing in them. There's just a little uh Button cell there, onoff switch and a vibrator motor and that's it. There's no I Don't believe there's any Electronics in these uh things at all.

and it's just. you know you can see the counterweight on the end of the vibration motor. but I just love the little the for factor of these things. and they go like the clappers.

They really do. check this out. Woohoo! Of course it tells you on the package code inside, register and play online. Well, it's not exactly uh, networked or contains.

uh, like you know, serial. You know, like toxy computer on Bluetooth is is going around. No, there's just a code inside here which you go to the website and you register and you can learn about real science. Fantastic.

Um, like, please keep these instructions like it's so important that you have to put a battery in there and they go to all the trouble about battery safety information? Oh goodness sake, See the switch on the bottom? You want to turn it on? Can you turn it on and it vibrates? There you go, You want to put it down on the ground? Oh look, oh, it's gone under the fridge.
