Hi welcome to one's favorite segment mailbag. Yes, we've cracked a thousand and we're back into it. Thank you very much Person on no one from Brook Street Melbourne is where they posted it, so thank you very much. I have no idea what it is, no idea who it is from and yes, I'm cutting towards myself because it triggers people all right.
Look, whoa whoa it is from John Put on your job cleaning up spare PCBs and I found this old actor process a card from an IMS TOC model I Ever saw no idea what that is? Well look at that when I was industrial WA blade thingamabob pcs two minutes. well there's not much to tear down I can take the lid off it. but yeah I'm quick squizz John is very kindly sent in this Alkyl what looks like, well, there's the number for those playing along at home and Alcatel-lucent Telecommunications PC Processor: it's got multiple Gigabit Ethernet oldest imports USB port so assume it's some sort of, you know Intel processor based system. It's got expansion cards like this I've taken off a lot of the top metal work so I'm not sure what that is but CPU Quadro I Don't know, you'd have to know what these things do, but obviously some sort of telecoms process a modern phone system I would assume because you know they don't use the old twisted-pair stuff coming in and analog systems.
It's all done digitally these days, so maybe that's what it's doing. or maybe doing some shrunk link or something I'm not sure. Anyway, this is another little power supply card that was actually mounted on a point one each header on the back. A huge heatsink that's obviously the main processor.
It might not be an Intel based system. we'll have a look. So I Got our memory modules here. What are they there? You go for those playing along at home? What is a four gig? PC 250-300 Me, you know.
But it's okay, so we'll salvage those. Thank you very much. They might come in handy and there's lots of stuff to salvage on this. and you can see the engineering that has gone into this thing.
Absolutely phenomenal. These things I Don't know what sort of volume they'd make these in? you know, the thousands? Tens of thousands? Maybe. You know these are not consumer stuff. You can see all the via fan out on the bottom of the processor and the other main chip down in there with the bypassing in there.
Absolutely classic stuff. There's a little little tiny O4o to jobbies down in there for your bypass in there. you go for those viewing in HD You can probably just see those, but the amount of engineering which goes into these is a phenomenal, no-expense-spared We've got obviously are some sort of custom custom connector with different length pins so that these ones that presumably be ground. the longer ones of the ground makes a contact first and then this one makes contact before this one.
so they're very specific in how they would like live, probably live. power up these things because you don't want to shut down your whole rack when you change these things, but you want some sort of predictability in your power supply powering up and stuff like that. So that's why they customize this with the different length pins to make sure it does first look little. DC to DC converter modules down in there. Is that one of those our TOA ones off the shelf. You could salvage that. Lots of salvageable parts on this. Look at the niche econ caps, thank you very much.
220 mike thousand via a hundred volt surface mount jobs Wow Got another look like a huge power brick down in there I'm not sure what's going on. there's another another power brick down in there vertically. You'd suck that out. No worries.
put that in your parts bin and these. Check them out. Spared no expense are there Europe Upside down. all the electrons are going to fall out LTM 4600 These that these are DC to DC converter hybrid modules and these are linear tech ones are really expensive to look.
you know if 15 20 bucks each in volume and they just put these all over the board. You know, because it doesn't matter. you're not trying to meet a consumer price when you engineer this thing to work and be reliable so you don't want to be around with your time trying to design a DC That is it. Convert it when you can just buy all these off-the-shelf modules and little hybrid bricks and stuff like that.
Wacom On job done. You know if he cares? If they cost 20 30 bucks a pop, there's another one in there. There's another one there. Who cares? You don't want to be wasting your time engineering a power supply solution for something like this.
So yeah, the amount of engineering is phenomenal in something like this. Anyway, let's go in and have a look at a couple of chippies. What's that? Some sort of Intel job? That's some sort of bridge chip I would imagine it a lattice glue logic down in there. Let's have a look under the heat sinks here, see what we've got and yes it is Intel But rather interestingly it's a Core 2 Duo A dates from like 2007.
It's quite an old B So we're talking in a 10 year old processor tech here, but yet none of that socket rubbish. It's a it's soldered directly down onto the mainboard. No worries, it looks like we have Intel coming out the wazoo. Check out down here.
Not only do we have some PCB mount fuses here, but look, we've got some 2d all current shunt resistors down in there. so obviously doing some current rail monitoring of some description and that was a SAS Drive controller Card Hard drives been removed and this puppy here is a shelf controller whatever that is I Don't know. You have to know your Alcatel-lucent Telecoms are systems. Once again, another big power brick on there.
Look at that, our man. just so each. so many parts on these things. It's absolutely incredible.
So thank you very much. John because there's a fascinating look at some highly engineered specialized telecom bits, a kit. You don't know how large the design team would have been to make this thing, but it would have been absolutely enormous. And it, you know what I'm saying hero is designing this sort of stuff. really. probably leading-edge stuff at the time, and a ton of engineering. And if you can get hold of old boards like this: I mean one, two, three, four, five, six, seven, at least modules eight should have to suck them out, but geez, you can really reuse those. They're very nice, but not a sneaky two over there.
so you can reuse a bunch of parts out of something that's seemingly you know, like absolutely, you couldn't sell this on eBay even if it worked. probably so you know it's just ancient tech. Don't know what's wrong with that, but those power supplies would still work, but really interesting. Thank you very much.
John for sending that one in good inside to all my German viewers are specifically Ingrid viewers if I'm pronouncing that correctly from coal Oh with two little ears on the top. thank you very much I think I'm going to have to carefully open this one based on the description. So sorry for you big knife aficionados, but it seems like it. Oh yeah yeah.
I might have done some damage with the big knife I Suspect So what slice and dice are open and let's have a look it is I paid him I don't know what that's off I am NOT a art connoisseur? Oh, it's written on the back dead. It's lengthy and very nice handwriting. in fact I will for the record. There you go.
Thank you very much! Ingrid My name is Ingrid and I am a big fan of your videos. although I do not know much about electronics I'm not uncommon I Became a pensioner two years ago. My son gave me a laptop with internet. He realizes big electronics projects even though he has no diploma.
Awesome! You don't need any qualifications to do electronics at all. Um I Once asked him where he got all that knowledge from and then he mentioned a private Internet electronic teacher I Guess that's me awesome since then. I Watch your videos quite regularly and I like to hear your charming voice and the humor makes me quite laugh quite often Next to the Internet I Discover our passion I Became an amateur artist Awesome! I Think painting is a great way to express yourself, especially when it comes to abstract terms. I Agree! So please keep it as a unique president.
I Will indeed, it's very nice. thank you very much. Ingrid That is lovely I Wish I had the ability to paint I've thought about several times actually taking a you know classes doing what I would love to be able to paint I Wish I had a talent to paint or sculpt I think that would be awesome so thank you very much Ingrid And to all those who watch without really you know having any interesting electronics, they get emails and comments like that all the time I'm very surprisingly but people just like my content like my voice, nothing likes my voice. There's Ingrid in a son. fantastic. Love that photo. Very nice good Anya thank you very much Mac Oh From Loves In Poland Awesome! How do I polish feels good on your nerve from Adelaide that's a return address it says never we've ever laid that would have got back to him. Stray is a small place, no worries, thanks.
Quite almost a deluxe Adelaide it's going to say Adelaide Ian Yours Teardown We've got a voltage detection stick that's a bit like a back there. the display The Primont Distributors in Australia Quebec The Volt finger. Awesome. This thing's it looks a little bit dodgy good on your nails.
two minutes teardown. Let's give it the finger and we've seen these voltage detection sticks before I'm sure but let's have a look at it because I Never asked how these things work. Well, there's nothing to them. So these things basically work on capacity of a coupling between the probe here which got then goes through.
that's one plate of the capacitor goes through a high value the current limiting resistor. here. our Bears has got a 74 HC one for just four threshold type stuff and then basically the rest of it just dries the lead and the buzzer or whatnot and that's all there is on. This thing is basically nothing.
So you might be thinking, well, where's the other plate of the capacitor Where does how does current flow well your hand? This sits inside here. your hand is around here like this and it's capacitive coupling into your hand which then flows down through your feet into the carpet or whatnot. And if we're talking minut amount of current. absolutely my new and there's only like you know, a point, one puff or something pico farads between.
like the wire you're detecting in here. but that's enough to make current flow when you've got a high impedance stuff. So yeah, it's just capacitively coupled. all it is, thank you very much.
Charles Alexian It's probably not how you pronounce a bit. it's near enough from Fresno in California Will my viewers in Fresno I have been through I think I'm beaver driven through I think I've been through Fresno sure I have maybe even stopped for lunch I don't I can't remember um my obey this is a TV blog executive Taylor's yes, not Austria And we do like typed letters as in typed on a real typewriter a brother SX 4000 For those playing along at home, that's great. Triple Five relaxing station looks on. Got a whole bunch of stuff I won't unboxed.
go to the main bench. Hmm I don't think I can help myself? No. Turns out there's actually a story behind the danger Push button cuz it. according to some old-timers they were used to destroy decoder circuits in receiving equipment bags, igniting some of the charge.
They burned up the sensitive bits of the equipment. Apex in Los Angeles I've been there I've done a video on that - link it in down below Had a case of them and had - and some of them have appeared to have the contacts wide in series as a simple means of redundancy. The contact action is unique, apparently. employees from SpaceX found them and many of them are on their desks. Brilliant! Wait until you see this. This is very sexy. A glass device is a Bayard output style Ient ionization gage using vacuum systems. This style has been largely a place by cold cathode types, but many are still to be found in use.
It works by bombarding the positively charged spiral grid with electrons from the filament. Remaining gasps will become positively ionized and Ford of the negative negatively-charged Collect the wire in the center and this will represent an electrical current that is proportional to the gas pressure. Awesome! This one has a worn out filament. Tada.
look at that. Ah, isn't that gorgeous? Well, it's got a port on it and it's just wow. Yeah, very cool. Now this tube here is apparently an experimental one that chose made and well here we go.
It's an experiment like dude - what? I'll let you read it but done yeah I don't know why can pins - and the grid is connected by ten and eight I don't own? Oh yeah, there we go up to P night? Sure, let's power it up. I See nothing growing, glowing red hot. Aha there we go. Sweet glowing goodness.
It's been the lights out though. it was barely visible with the lights on. I've got a whole bunch of relays, a couple of LCDs and these big huge standoffs. Light switch is only three F Jobbies.
but look at the width of those contacts. Wow Actually Charles included a note on this so he actually had these commissioned manufactured by Us Witchcraft to replace a Oculus. Jensen Great name I CLIs brand that they don't manufacture anymore so they had to replace and so they got them to custom make them for you and they will. Companies will do this if you have significant volume and stuff like that.
No worries. Hi to all my Austrian viewers and sorry to mine hard Kissick Therefore because this is a time-sensitive Kickstarter sorry I'm yeah this was like sent quite suddenly that this is sent quite a while ago, but it was like I just wasn't doing my Oh bags at that time. so unfortunately I couldn't suck, couldn't do it. but let's check it out.
it's obviously some hot. Oh I look at that fancy panty and there we go for it. You QR code aficionados and see how we're in this. No I guess.
slice and dice that open be be math. Oh I got some rulers. Oh okay, cool. PCB Rulers I Spot a problem right off the bat.
Sorry, let's take a look at them but that their flexible rulers Meinhardis sent in. These are cheat sheet rulers and yeah, they're not PCB they're made out of a you know, a plasticy type thing anyway. Um, these are designed to be put inside and self designed to be our little cheat sheets cheat sheets during the exams during final exam and have all the various formulas on them. Obviously in these exams you're like it's an open book exam or something. or you're allowed to like bring in a sheet of paper with all the formulas and calculations and stuff on and they're all math related. They're not really, not so much electronics related so it's all the mats and math exams. I Don't quite understand the B concept with all the whole like the holes in it I Don't get it. And anyway the r01 criticism: the 0 should start right at the end so you can do and stop measurements like that anyway.
mean had reached the modest 2400 euro goal although I guess that buys you a lot of these I don't know how much our tooling would cost a lot of these. not a huge amount I'd imagine. But anyway, met the goal. So I'll be getting down below if you want Molly's cheat sheet rulers for you math nerds.
that's not me. sorry and all my viewers from Ohio formally where Chris Gavel was from and in particular Zack Corolla Um, at least we're not Detroit sorry oh I might have to edit in the clip from that anyway. Cleveland this is Detroit Critter internet me Me: YouTube mean thing. Fun times in Cleveland again Cleveland Come on down to Cleveland town.
Everyone under construction since 1868 see the Sun almost three times a year. Let's look like a Scooby-doo ghost town. buy a house for the price of a VCR It could be worse though. at least we're not.
Detroit we're at the Troy's what do we got? Add that we've got a alarm clock of singing. does it do anything else to me to tear down and Milo's all. I could use those velcro straps Sagen, it's just a again awesome you got here, huh? Not sure what that is? what is that? Oh oh barley fleshy fireflies. We have the American innovative USA alarm clock.
Apparently this one could allow you to set a different time for every day, which is I rather interesting taken away an expensive piece of rubbish. The never late executive selling point was because oh, it is good to be able to set a different time for each day of featuring our company's smartphones. The knob would tend to slip and double jump. Battery backup never worked.
Audio worked well down the low price point apparently. Yeah, let's tear apart. Well, this is rather odd. Like this sits on there like that speaker on the bottom I Get it because just sits off like that to direct the you know little like a little acoustic II kind of.
Boxster I Get that out. But look at, that's like the sides. Why are the sides like that? I don't entirely get it, huh? Anyway, can this come apart? Yep. way hello.
What's that? Hello Dave Someone has pre torn this apart. What? What is that? I've got no idea what that is but hello Dave Somebody new at the factory, but that's interesting. Check out how there assembled the LCD on this thing. Look at that.
the LCD Modular heaven. Don't think I say I haven't seen that before. There's obviously I designed that LCD controller to like sit in a cutout in the board and then they've just put the pads on the side and then bridge them over like that. So that's a rather interesting technique to get a low form factor like that rather than have it. you know, a pin header sticking out and stuff like. Not that they needed it with all this depth and everything else, but that's that's. rather neat. Anyway, we've got double sided load on these up there.
yet. that's the receiver board down there because there's our ferrite as a good old AM ferrite rod and just a single chip Am/fm radio receiver and like Bob's your uncle got a trainee down the bottom there and one what a nice speaker. It's like yeah, like your but the engineering are sort of neatness and cleverness. with the LCD in that cut out kind of ended with these tiny look how they've actually gotten these are off board at wiring little tiny.
like what four, four, five, six core wires going over to these tops. which contact board over here? that's hideous. Somebody had to hand solder all those. look at that.
look at the contact on the PCB wiper contact. They went to all that effort. I yeah that's a weird and that cabling like for production. that's a nightmare.
Why would you go with that? Unbelievable. and these things are bike safety flashes from over 15 years ago and it still works. Do you bang on like that started? Oh yes, there we go. Alright, Beautiful.
I Don't know how long do they flash for like a minute or something? I do I Guess the vibration still keeps them going. Yeah, neat, but yeah after as well. What about you know a couple of coin cells in there and you know Lr44 or or something like that? I'm not sure like they actually require to force to get them going so I'm not sure how they keep going on the bait and blank. Maybe you know you stick it on the frame and they did the vibration.
It might keep them going or something, but hmm. interesting. Can't really tear those down. You have to Dremel the whole thing apart I See and all my viewers in Singapore we don't get many from Singapore doing a lot Singapore it's a good probably my favorite Asian a stopover on the wake of Australia like it's down on the bottom of the planet or top depending on your perspective and yeah I like we generally need a stopover if we're headed to what? Europe So yeah.
anyway. oh sorry thank you I know from get person unknown in Singapore Oh gee, this is comprehensive I'm a guy living in Singapore who we should see remain anonymous. That's cool, but have been watching your show ever since episode 395. This note is going to be a little bit long so read only underlined text if you don't have much time, we've got a black box.
It's actually called a black box. um and it is black. we're not. um and it's like it's a one of they are two set-top box to second day. Now this is a pay-tv piracy box. Um I go figure. I'd like a C1 stream box and I didn't though hey you kids like just like it looks like a legit product I mean it's one of these little hack together. jobbies conceal it a little Wi-Fi module hack in there and all sorts of stuff and apparently has ripped already ripped some parts out of this puppy.
but it connects to the Wi-Fi and downloads the encryption key stored in an off-site server and some of this place locations. It unbelievable. Ah, there you go. So I don't know? Is anyone still getting pirates cable? TV with you know like guides get Netflix I mean yeah I can probably get it all for next but it's just so convenient I Don't know, we don't have really what we do have cable TV here we have Foxtel but I don't think anyone bothers to.
you know it has any mark. It's not big enough to sort of hack together some box to get you Foxtel I Don't see or not it home has it anyway. so I don't know, are you pirating your cable? TV but it's no down below anonymously. but NSA is tracking you anyway.
So Max and now anonymous friend has written very comprehensive details of this box and how it works and stuff like that. So for those playing along at home you want to have a retu that go for it. Another one from Germany this one comes from all's Door from Marcel Henson Thank you very much myself. Let's check it out in description and it's just a lumpy thing up.
What? Why do I have a dummy? Um oh, you're what. This is great. This is great. It's a it's a 50-ohm Terminator dummy.
It's not a fan of dummies. They're not good for kids developments I Don't like they're not good for the mouth development. Their mouth doesn't form quite well apparently so. but that Wow 50 - it's gold.
hi Dave I'm sure you are familiar with Terminators because the electrons are shy and afraid of photons. They get scared when they reach the end of an open cable and run right back the little buggers. hence the Terminator was invented to keep the light out of coax cables. Yes, true story, it's on.
Wikipedia We have at a first Advanced Industrial Labs I Love the name of the company I wish I thought of it I Proudly present to the EEV bore the latest in termination technology. If you're planning to have another child or maybe know a fellow engineer who has a suitable host device, you're welcome to try it out. Thank you very much. Marcel Technical specs: impedance is 50 ohms of course 20 DB my noise reduction and plus 400% sleep mode duration.
Awesome! I Just is there anything better? Look at this what it is. it's just fantastic. 50 Oh duh me load Thank you very much reflow. Ah slow.
Our reflow capital are calm for what we've got in here, it sounds interesting. We'll try the sounds like there's multiple things in here so let's check it out. Four: Oh well. wow we're going to KITT and hey sweet oh it's a yes right? I've had this. been sitting here for a while I'm not sure I think I saw this. um yeah the Reese law was the Kickstarter or something our has talked about on the eevblog forum or something like that. it's a mains in and a red button on there with a thermocouple and it's just be re flowing plate so you stick your board on the top and apparently you can reflow your board. so I'm not not something I can demo on the mailbag way Dave I hope you like my a reflow our project.
It is really the inconvenient use. It comes with a small test piece of e everything you need, one screw open, teardown all. apparently it's quite easy. and this is the note.
Yes, it was a crowdfunding campaign. apparently this is the one that's a ship so that's the note that our ships with it. a few issues and all that sort of stuff. I like that you know being honest and I tell everyone about the you know in issues that come with the ship product.
anyway. I'll link it in its many maker.com with a hyphen in there. but there it is. there's a reflow, er it's just the plate on top gets hot, you stick in your mains I don't know.
well if you have to hook an external thermocouple long haven't seen it yet, but presumably it will. They is programmable with a profile so you know it's it's pretty crude. I mean like all the corners are sharp, you can sort of like cut it raw like that I could probably sly if I put my hand down there I might be able to slice my hand open like that. So it really is a you know, a sort of a problem, you know, practically prototype II type thing.
but they have shipped apparently and what was? crack it open a little. Sure enough there was one giant screw on the bottom and today we're in like Flynn Well I got some real insulation that's I don't know what sort of insulation that is. some sort of fiber II fibrous type insulation. You need that of course to isolate because this thing is going to get hot I mean it's solder in temperature and it's not much doing down there at all.
It's neat enough. I guess it's all self-contained on one PCB main straight in. its mains are fused down there with the proper shrouded, a fuse holder on there and well, that's about it. And they've got a 3 watt DC to DC brick converter down there I'm not sure why they needed a three what job II that's actually a lot arm cuz the heater is going to be our mains heated of course.
Um, so yeah, that's a fairly decent sized brick, so not sure why they needed that sort of level, but it must all be all the smarts of it must be on the bottom of the board, but it looks like there's like a little. our Wi-Fi modules down in there is that one of those are esp8266 s and left for us is very kindly included the PCB so we don't have to take this puppy apart and we should be able to see some. Yep. mains isolation there. look at that. Very nice. No worries whatsoever. and there's all your control stuff on the bottom side and that was going off to the Wi-Fi module over.
yep, why fight there it is over there and a fan, buzzer, lead, and your thermocouple input. So that's some neat little board. I like it. and it included an experiment as I can't with some PCBs either for reflow soldering practices like the one that's got the thermal pad on the bottom.
that's pretty neat and yet we've got the a stencil. Actually, that's probably not it. Maybe that's just a dummy board I Think that's the real yeah, that's the real board for re flowing stuffs and paste and thermocouple. and they and I assume that's a spreader is it? Yep, you really need a plastic.
like a just a simple plastic credit card or something like that. does the job better than a fixed metal one like that. For a spreader, a plastic car would have been much better. But yeah, that's a little experiment if kept that either comes with it or you can get separately just to get you started.
so that's interesting. It's not something I can play around with I should play around with on the mailbag here. So let's do a separate video on that and it's got a fair way to go to be like a commercial quality. You know, a commercial quality product.
It's sort of a bit prototyping at the moment, but you know I am curious to see how well it works because you're really because fiberglass is like a thermal insulator, so you've got to stick that on the surface. Okay, the surface heats up and yeah, you might be all you eventually get the heat transferring through to your boards. but it's by no means the best way to do it. In fact, this is generally a hot plate like this under a board will be used as a pre heater.
So yeah, not really for soldering. So I'm you know I think it might have to stay there too long to get the heat transferred to the pads on the top. You know it might be okay if you've got one of these are you know, thermal pads on the bottom which then can conduct heat through to there. but that's that's like pre heater type stuff.
So yeah, I don't know how well this concept is going to work. They're taken basically a pre heater concept and tried to make it into a you know, a reflow oven replacement. which it's not I find it hard to believe it's going to do a you know as good a job as a thermal oven. they're just the thermals don't make sense to me.
but hey I haven't tried it yet. So I have to do that in a separate video and I'll link it in down below if you want to check out the reflow. There was a thread a while back on the Eevblog forum on this: I think I know all my kin in viewers and Andrew in particular no last name. We have a gift thank you very much! So let's see we've gotten from Canada It is a high day greetings from Vancouver I Love Vancouver Great city to this day I Still regret when I was in Vancouver Deciding not to go to a Steven Seagal concert concert not movie concert. long story. Anyway, do Not open this on camera. Okay, and we've got a Trans or the original hardware wallet. Okay, it's A.m.
Oh okay, it's a it's a Bitcoin D wallet. Is it treasure or other? What other type of digital wallet would you have? I'm not sure Hardware? Well, it doesn't say anything about Bitcoin or anything like that, but usually that's what hardware wants it for for storing your Etherium or your Bitcoin or your 10 million other bloody Oakland's Sure enough, this is a traceur Hardware Crypto Bitcoin wallet up with a little LCD designed to securely store your crypto currency and the letter hi David from Vancouver more on the IT side. So how it works is the private keys never leave to Azure and the device will show the recipients address directly on display so you can be sure you send in the funds to where they want to go. Think of it as a drastically overgrown one-time password token which adds an unhackable something.
You have something you know. it makes them a high-value target. No kidding. So he wants the insight in the overall build quality and durability advice as well of his tamper resistance and tamper evidence stuff.
And yes, I have read this as well. Someone's performed a power line monitoring attack and they were on this an early version of this and they were able to retrieve the private key from it, but it is said it has since been fixed like two years ago 2015 I Believe that was fixed. so that was a long time ago. And yes, I did not open the other letter on camera which says do Not open this on camera and I've opened it and this is why I can't do a teardown right now.
There's something in the additional in that envelope that are yeah I just can't tell you about and I won't be doing a tad out of this right now, but possibly in the future, we'll see. Sorry secret squirrel stuff that crazy Aussie bloke that's me. Um, let's open it up. thank you very much Bunt and Brune I can't pronounce the letter Sinead onl Um, never once is this NL this is going to be I Don't know.
It's kind of wrapped in electrical tape is it got it? Wow It's a cheap-ass multimeter. It's already broken. Oh dear oh look, it comes on to second teardown. Do I have to? At least this one has a ceramic fuse over there for the 10 amp range.
Act like you know, whatever. Hide all my Spanish viewers in particular Alberto begun to you good on your Alberto Oh, we may get too many from Spain all those Spain probably punches above its waist in mail. We're possibly almost in this country and I've been displayed. Let's have a quick squares.
What are we go up? We have something in a black felt I'm sensing retro cray we haven't ever to. Kraig calculate It's a learn learn thing. It might be one of those. um that. Craig in 100 it could be one of those language translator things. linguistic Oh linguistic Oh Yep, I was right and we've got a bigger this two book. ABC Basic Kaneto Alberto Silver Whole Book ABC Basic Connections Woohoo Hey ah to rap for our protection, let's have a quick quiz. Alberto Just like a Kickstarter awesome wait I have I'm Alberto you probably remember 15 outs on Pig Hi Pinky Pink Hi Xxx Comma Sounds legit I'm only kidding.
Download: it is legit. Trust me, it's safe for work I'm super excited Announce that I'm running a Kickstarter campaign for my latest book ABC Basic Connections send your pre-release copies. Tell me what you think I Hope you love it. More information ABC The book calm and unfortunately it's already ended on IndieGoGo but raised a hundred and fifteen thousand euros.
Double the target for this Basic Connections and it's beautiful. Ring binder love it and errata as well. Shouldn't get any rather any more do. It's basically just information on our do we know and stuff like that.
So here's all the different pin outs and things which I believe a lot of maybe all of them are available on the website, but this is in book form and so we're just showing you notes, schematic symbols and stuff like that. We've got some owns, lost a phones or triangles with up the wrist ins. This to stuff. it's beautiful, beautiful quality.
I Love the artwork and everything in this. It's just absolutely fantastic. No, this doesn't have the Creative Commons on it, the ones we saw on the website actually have Creative Commons So anyway, this is how to hook up all sorts of stuff to. Arduino This is absolutely brilliant.
I Like using big graphic layout of this. imagine how long this took. It's absolutely stunning I Love it. Awesome work and it yeah I can see why it actually warning in Will Robinson Why got 106 10,000 Euro back? This is a lovely reference resource.
You know, sure you can just do it in a PDF but it's not the same as having this and look at this four fold-out porn or with this centerfolds. Oh yeah, this is great. This is fantastic. anyway.
if you are dealing with Arduino you're a beginner and you want a nice reference book for hooking up stuff, check it out. Do yourself a favor. Hello Bongiorno Hands up if you had one of these I Can type that in and go hands up if you have one of these. a Craig Ember 100 Of course any smartphone can do the translation now can even probably I listen to the person's voice comment and then just automatically tell you what they said.
a different world Oh wow, look at old school. This puppy is 1979 I Kid you not Wow What's an SL 90 240 Fourth Week 79 mating Singapore A lot of chips are made in Singapore Back in the day, well look at that little budge board over there. Is that a said? A little concern is that a nice listening doctor is it? So that's a little switching. No switching. What? That's some sort of switch converter. Anyway, look at the finest bodge board over here. Vertical resistors? Fantastic. Thank you very much.
So it's basically just a processor. A vacuum that? yeah, I presume. vacuum fluorescent display down in there. and the cartridge rolls which you can.
Oh, there you go. That's the Italian wrong. Well, Copyright 1980 Wow So there it is. I'll you that beautiful? So yeah, it's just a like it doesn't It just died.
It doesn't do anything fancy. it's just you type in the word and then it maps it to a ROM entry and then displays the mapped word. But anyway. there you go.
You can put three different languages inside this thing. This would have been the Ducks guts back in Davis would have been like black magic technology back then. I Can't get enough of the nipple, you know? I Love it. Well, I'm curious to know now.
I can't read them all I Guess I could just translate the manual couldn't I using one of my newfangled smartphone thingies or googly or whatever it is because I'm like I learn I presume that's a learn button on the front. but this is like a ROM based thing. so like I wouldn't expect it to do anything like algorithmically fancy I Expected just a map. Are words in one language to another and that's it.
But based on the room you know entry content. They probably said put him in alphabetical order in the ROM or whatever and then translate them over. but I don't know. Hmm, maybe it does a little bit more, but I wouldn't have thought so and unfortunately it doesn't work.
the lead comes on. but yeah, it's nobody time. So that's an absolutely fascinating little module there. How they've bent the pins over on just a standard ROM put a lovely label on there and made their own little sort of you know, like little plugin sing with us handle with it's really rather clever.
I like it. So anyways, thanks for everyone who sent in something for today is mailbag and story if I haven't gotten around to yours yet. I Will endeavour to do it next time anyway. if you like my o beg, please give it a big thumbs up.
Catch you next time you.
With the rulers, I'm assuming they are going with a hexagon motif because hexagons are the bestagons.
Always glad to see kickstarter advertising go to waste ๐
First Advanced Industrial Labs 50ohm terminal its geat! how can I buy that?
The problem with 0 on the end of a ruler is that the ruler wears down and then does not stay accurate. You see this especially in drafting rulers. Having said that, I want my rulers to start at zero on the end and I can just replace them
horrible painting lol
Crocodile EEV !
That's not a knife this is a knife ๐
That's not a knoife
Now that's a knife
"you don't need a qualifications to do electronics at all."
I loved it. I am also a zoology student and dev regularly.i love this channel โค๏ธโค๏ธ.keep it up.
i like mailbag
Having absolutely no memory of Fresno is almost certain proof that you have in fact been there.
Don't feel bad about being late with the kickstarter, many of us save mailbags for months or years until we're sitting around with nothing to do. Here I am watching this for the first time 3 years later.
This "katana" so satisfying
Wait! Is Foxtel Australia Still Afloat? Why would anyone be so stupid and pay for Advertising TV when FreeTV or Freeview is much the same but it's FREE!!..
Only Media I pay for is the likes of Netflix, but the day I see an Advert on it, is the day I will give it the Flix err-Flick.. Dumped yo a like BTW..
Very nice voice I can understand every word
Have you ever dabbled in gold reclamation with all those PCBs you collect?
Stop touching the circuits incorrectly. Touch the circuits on the side.
I wish the knife were smaller and the voice are not so horrible.
Those safety flashers appear to be something you screw onto the air valve on your tire. They flash when the car is rolling.
