EEVblog #1003 - Mailbag

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
