Hi welcome to everyone's favorite segment. Mail Bag where I open my mail. Let's get straight into it. First suck of the Sav comes from the Old Dart Royal Mail here from someone everyone knows Mike Mike Harrison Just undo it.

Yes! Mike from Mike's electric stuff and he's sent. uh, thank you very much. Mike he has sent some sort of uh motor? is it? Well, let's crack this sucker open and uh, see what Mike has sent. If Mike has sent it, it's bound to be interesting I'm sure.

So if you haven't of course, um, seen Mike's video blog. he's a fellow YouTube video blog hi Dave Found this for 99p on eBay UK and thought you'd appreciate it more than me. Uh, seems to be basically working, but the front button seems to a lot of springiness and stick down Parish Rubber Yeah, probably maybe fixable. Putting a fine wire coil spring between the button cap and the body.

There is mysterious yellow jump Link in the battery compartment. No idea what it's for. All right, let's check it out. Mike from Bikes electric stuff.

Here we go. Ah, it's not a motor, it's a oh look oh yes, the Hyoki Cal High tester. Oh 99p. What a score! Mike Brilliant! Thank you very much.

Um, this was on the Forum some time back. If you don't know what this is folks, it is a combination calculator and multimeter. Two of my great loves I Love calculators and this is like the world's I Think the world's only combination multimeter and calculator and you might know might know the name Hyok. they're a Japanese uh company and they've um, does it work? No, it doesn't work.

Oh, hasn't got a battery anyway? we'll find out. But yeah, Combination multimeter. There we go. Positive and negative input.

Not very robust at all. I mean that's it's pretty creaky I Don't really, you know I don't get a good feel for it, but this is um I believe from the late 80s I think I'll have to double check this 200 Ms DC to 1,000 volts Pretty typical 2 volts doesn't have Mill volts uh AC unfortunately. Current: Yeah, not much. There's no high current stuff in this.

It's only 20 milliamps, 200 no microamps and 200 Ohms to to and low power Ohms as well. which you don't get these days. It's got the low power button. Yeah, low power.

Ohms there it is. Um, for those not familiar, the low power Ohms function basically uh, limits the test voltage in the Ohms function so it doesn't turn on any. Dio Junctions This was very common back in the day. Um, you know the you know, 1980s vintage up multimeters.

A lot of them had this low power Ohms thing, but it doesn't seem to be very, uh, common today at at all. So there you go. Let um, whack some batteries in it and uh oh, 981 is it? There we go. Is that? I assume that's a date code cuz that's not not the model.

The model is 3208, so I assume it Is 1981 vintage. Let's whack some batteries in see if this puppy works well. I whacked a couple of batteries in it and it does seem to work. Calculator: Works Anyway, um, even though it is Switched Off So obviously low power calcul circuitry in there, probably completely separate would be my guess.
Completely separate circuitry in there dedicated chip, just completely. uh, just uh, hooked across the battery cuz low power calculator chips? of course, you know, a dime a dozen. even back in uh, those days, it'll you know. Run Forever on a couple of ablea batteries.

basically the shelf life of the batteries. That's why they don't bother put in it after the on switch because you might as well just leave it permanently on it. you know, draws like a micro amp or something like like that. so it works all the time.

so I'd expect uh, them to, you know, not be tied in any way. The calculator and the multimeter entirely different circuitry. so let's uh, turn it on and the multimeter seems to be working I do have it connected up. Oh there we go.

It took a while, it took a while I've got it hooked up to my 1K Precision resistor here and it's a little bit out, but uh, it did take some time to get up to that Val you so yeah, it's not the not the world's quickest thing that's for sure. Wh there we go? yeah, takes forever slow as a wet week. Now The first thing I noticed is that this screen is awful. It's atrocious.

One of the worst screens I've ever seen. Now this is on an angle. not, you know, not hugely off vertical by any stretch. But look, it's got some weird sort of.

you can see the uh, background pattern on that, almost as if like it's a dot matrix. but it's not. It's a seven segment display, but there's some weird sort of grating thing happening at the back. I'm not sure or it looks like the back and really, you can only it's you know the digits are only crisp and clear when it's directly on like that.

I mean that I tilt it to a small angle and that's just me almost over the top and that is just that is awful and it just gets, you know, just horrible I don't know what type of LCD that is and you tilt it in the other direction and it's not a huge amount better either. Well certainly is. Well, flake. Oh look, I lay the thing down on the table and I'm getting 350.

ohms and I just tilt it up like that and it goes to a K. So there's something horrible going on inside this sucker. Oh my goodness. Anyway, as far as the calculator functions are, uh, concerned here, it's not entirely fully featured.

There's no engineering mode, for example. um, but you know it's got all the basic uh, trig functions. It's even got rectangular to Polar Polar to rectangular uh conversion uh, you know what else? dedicated one onx button, dedicated square root, dedicated um register exchange key I Like that so you know it. it works.

You know it's a reasonably useful scientific calculator, but yeah, I don't know. The whole concept is just. it's just Dicky You need the right tool for the job and it does have a continuity buzzer of course. Absolutely horrible, but it is at least a latching type.
And once again, that tilting thing 3 volts in this 9vt battery which I think is dead and there we go. 7.07 When I tilt it, you got to be kidding me. But in any case, the that is actually uh within spec so it does actually work. What is it? Got a tilt switch in this thing or something and there's only one thing left to do.

Crack this sucker open. We may have to take the batteries out as well. Um, yeah, there was talk about this calculator on the Forum and people uh, posted links to it and that was I don't know. Maybe 6 months ago and I did try to get one on eBay but I think they were uh, not available at the time Tada There we go, we're in like Flynn Well looks like we're going to have uh mostly through whole construction on here.

although I expect the calculator part to have a quad flat pack or a chip on board. Uh, probably under I Don't know whether or not it's under the LCD probably on the bottom side of this board. we'll have to take it off curiously. Look, there's a copper shielding tape just like on the battery.

Why do they need that? I'm not sure what they're doing. They got the negative from the battery over here coming over and connecting to that and presumably something connected on the other side there. but I don't know. that's you know.

Um, got no idea why. It's a spark gap between the inputs there. so that's you know, a modum of input protection. I Guess I Wouldn't expect to find much else in this.

I Don't think this is uh, uh, going to be a hugely rugged multimeter. that's for sure. Check out those segments. Obviously the LCD has degraded massively over time.

You can see the shadow on the bottom. uh, part of that, but that is, that is just awful that is. There's something gone horribly wrong with the Uh Liquid Crystal in this stuff and it's just, oh, faded out. If anyone knows what the failure mechanism is there, um, please let us know cuz that is horrible.

I Haven't seen anything that bad bad in oh forever. I Think look side on. You know it's not too bad, but you can see it just faded out. That is awful.

Okay, now it's becoming fairly obvious why they needed or what that copper shielding is for. They've got it. Between all of the ribbon connector, they've got the clear ribbon there over there. No, there's nothing connected to the other side, so it literally is just a shield over there.

I'm not sure why they why they needed that really. I mean you know, um, at the frequencies this thing's working at I'm not sure you know why they would bother with that, but eh, you never know what's that under there that oh, that's the fuse. Okay, there we go. So that's that's our fuse connected in there little pissant wiring of course cuz it's only like 200 milliamp.

There's no HRC or anything in this and it's really is just bodged construction. Anyway, let's have a look at the the bottom side of the calculator. There we go as I said, uh, quad flat pack. They've actually got two of them.
NEC Chipset. Um, yeah, they're all custom for the day and uh, what is that? Let's have a look. Is that a little regulator? No, that's just a C945 transistor. Boring as so really, that ribbon cable is just effectively bringing all the segments from the multimeter uh, chip here over to the top side because you know there's there's nothing else.

it's just the the calculator's fully self-contained on here. so the only thing it needs is power the 3vt power from the batteries coming over so it only needs uh, the two wires there. the rest are all for those segments so you know it. It really is quite a cludge, but oh my goodness, look inside this thing.

I've got the custom ganged switch mechanism from K Bayashi Co Limited. We got a big ass piso uh buzzer there which is pretty uh pissant for its SI actually and it looks like two custom single in line. yeah, they are single in line arrays there in a uh, molded package and uh, they're probably oh no. I was going to say the voltage dividers, but look at this.

This is a rather interesting arrangement of is that a you know, is that a voltage divider there and is that a strip can I lift that up? I wonder let's give it a go. Yes, I'm not. uh sure what's going on there with that, but that seems to like have a It's almost like it's a strip of Fr4 on the top just joining all those resistors together creating a single in line single in line array. and then uh, we've got a bodge resistor over here.

Like really nasty stuff. I mean they had Sip resistor packages and they've just in back in the day and they've just rolled their own and a trimmer cap for the calibration presumably huge, big big uh 104 ceramic cap here. um probably you know they needed the voltage there I guess but you know there's no uh, isolation slots in this thing or anything like that at all. Really, it's just quite a bodge.

I Mean here's the cable coming in from the top from the positive input terminal down here. It runs under here and then just joins bodgy down in there. I Mean this thing is just awful. I Think we might have a fuse down in there by the looks of it.

Couple of dodes for protection on the input and well, you know, not much else. So I wouldn't be going measuring the mains with this thing. that's for sure. There we go.

That's the underside of that single in line resistor array there. They they've just shorted them all out and sort of like glued it in place like that. Jeez. And by the big bulky nature of this custom molded single in line package, you would think maybe they've done something similar to this resistor Network here and they've just, you know, got some parts in there and then they've just molded right over the top of that thing.
But you know a god, you probably never find data on those. sorry. that white wire on the other side's actually the uh, negative input terminal. The positive input terminal is over here of course.

as I said, they got a spark gap there. sold it in the wires. just it goes to the fuse here and then it jumps onto the board down in there. it looks like we have some heat shrink over something.

Maybe the uh input protection resistor, probably our high voltage input caps there. And those two over there are probably our sampling caps cuz they're right next to the single chipset. uh, multimeter chip which was very common in the day. sing U You know, quad flat pack like this dedicated in the single chip.

These are all the rage back in the early 80s and well, mul. most multimeters today are still exactly the same. just a single quad flat pack. Nothing's changed in 30 years, so there you go.

What more can you say about that? It's a pretty atrocious multimeter and not a great uh calculator. Really, once again, complete, you know, and basically a a product fail. one of those marketing wanks. oh let's you know.

combine our B novel and combine a multimeter and a calculator and sounded great in the Uh Design review meeting. and then well, you know execution is is pretty poor and essentially pointless cuz you always end up when you try and combine products like this. you always end up just doing it half ass. and you know, half ass multimeter? half ass calculator H Don't know why they bothered, but hey, at least they gave it a go which is better than nothing, so that is rather unusual.

Probably the world's only combined multimeter and calculator. I Don't think I'm aware of another one if you are. certainly, uh, leave it in the comments and I stand corrected on my comment that this thing, uh, wouldn't have any connection between the multimeter and the calculator. It certainly does.

In fact, it has a shift button here which shifts the current reading into the calculator so that you can operate on it. and there it is. 66 something, 66.5 and it even knows it's Millie Look at that. M Volts.

Fantastic! Oh now I'm actually quite excited. H So it's really interesting how they've integrated that functionality into this thing and you know it would have taken a bit of effort. They couldn't just use off the-shelf calculator chipset. It would have had to have some sort of data interface and it transfers it very slowly.

so I don't know whether it goes over probably goes over a uh a Serial interface. given that I think a lot of um, those, uh, those connections on the um LCD there are well on the the cable going between the board are for the LCD uh segment. So yeah, they're probably running that thing over a Serial line from the DMM chipset which again would have to have a custom output for that over to the Um calculator chipset. Really fascinating stuff.
And yes, I did check online. The original data sheet for this thing is available on the Hyok website and they of course list it as discontinued. It want to be it's 32 years old, but it's still there. Excellent quality scan of the original data sheet.

It's just brilliant. Definitely check it out in the links below or on the EV blog website. So thank you very much. Mike for sending in this awesome bit of um, multimeter and calculator history from the 80s.

It is just beautiful. Really? is I mean you know it, it's practically. You know it's a poor multimeter and it's not a great calculator. but eh, at least it's novel and we have one just arrived from St Petersburg in Russia We don't get too many from Russia and I'm not sure how that name I presume that's somebody's name who sent it to me and it contains well.

I Guess I see Parts Quantity No. 300 100 pieces not value. So that's the value. All right, let's crack this thing open and see what we've got Here we go.

How does it open? How does it open? No. There we go. don't get too many from Russia So hi to all my Russian viewers and uh, everyone from the former Soviet Union how many Uh states were there in the Soviet un when it uh, broke up I Don't know. off hand there were a lot and oh looks I got some crusty old parts.

We have a note: oh it's very brief. hello Dave I Found some old IC components made in the USSR. Maybe it can be useful? Yes, the USSR um the former Soviet Union Oh thank you very much Oleg There you go Thanks Oleg Let's have a look crusty old Parts First thing you got to do. hang on.

Oh actually not really. the cross old component part smell I Was expecting. Got some uh, axial resistors here. some nice ones, but these are all made in the former Soviet Union Now I can't read those presumably Russian symbols there, but 1 R5 of course means everything.

1.5 Ohms I Presume that's the brand trademark. so if my Russian or Soviet your former Soviet Union friends know who the manufacturer is, please let us know. and I presume that's 100 Microfarads in Russian 1985 vintage I presume that's the date code Fourth Week 85 We got ourselves a single turn trimmer here. Looks like a multi-term trimmer, but it's not just tried it only single term and 330 is that Ohms.

I Guess it is. Could be 10% and it looks like we have a 1986 Vintage 100 Nanofarad high voltage cap and that's obviously a 250 volt 200 microfarad cap. and uh, interestingly, it's only got one connection on the end like that, so the other one. look, you know there's no there.

Nothing's broken off so it must be uh, the other end is the can. Wow, this is a real interesting trimmer cap. Look at that. it's designed to I don't know whether it's PCB or socket mounted or something, but tiny little trimmer on the top there and uh, look at that 5% uh, 680 Ohms presumably or is that two? Meg I'm not sure but yeah, 10th week 1990.
This one's pretty recent, but that's a real interesting package. Looks like it's been Salvage got some solder on the leads and they made their own micro switches. There we go. Beautiful! So you really got to wonder about.

You know all these companies and all these people that worked at these companies. You know it must have been huge manufacturing all these resistors and the capacitors. and the you know, all the semiconductors and everything in the uh, former Soviet Union So maybe we've got a viewer who used to work at one of these. or if they're um, still going presumably.

um, there's still plenty of local manufacturer left around there. but I don't know? Um, please viewers. Uh, let us know the current state of the industry there and if any of these uh, factories and manufacturers are still going, next up we have one from Pico in Brooklyn New York It was teed up that uh, it'd be sending this and it is. Well, I won't tell you I'll open it up, you will.

That's what it's all. What's the point of me telling you? That's a bit of a bit of a let down, but uh, they sell this. You can buy it on Uh I believe you can buy it on. um uh, what's the uh Tindy Tindy Anyway, let's have a look and this will come in handy very shortly.

In fact, this week it's the pie. Pico It's a solder paste dispenser. It's a Pico paste pressed and basically what you do is you put the syringe in here and it dispenses a set amount of sold paste. Looks like a really nice bit of Kit We have a letter here from Jonathan and uh yes, we did mention this thing on the amp hour so that's where he heard it and uh, sent it in.

Comes with a whole bunch of uh, tips and more can be found out. Yes, I was right. Tindy Doom They've got a store on over there. Um, Tiend is a place where um, you can, uh, buy and sell uh, your own uh kits and electronic hardware and stuff like that.

It's really quite neat. Um, some quick guidelines. Don't try to use a tip. three solder place with any tip below 22 to 20, 20 to 22 Gauge particles are just too big and you'll get poor results.

Yes, because the balls the uh solder paste are little little balls, little art particles. I've tested type five with needles as small as 27 gauge without issues. the material continuous dispense after releasing the lever first to press the trigger. tip.

For young players, the taper tips are best for things like adhesives or when you absolutely want to avoid scratching abroad. Excellent! Thank you very much! Jonathan And there it is. It's a really neat thing. better than using a syringe because you can't.

You know with a paste syringe you can't get. you know with your thumb you can't just get an accurate dispense of the paste. It is very difficult. Very tricky bit of a fine art and you you know overshoot and you get too much past oozing out blah and it is made in.
South Africa Awesome! I All my South African viewers. The Pico Past press works like a miniature corking gun. It's the best way to easily and accurately apply solder past. SMD Adhesives: another high viscosity pace and liquids.

Press trigger while pulling down the plunger at lease, trigger remove and blah blah blah. Tips: dispensing should take little effort, if not, try a material lower viscosity. Awesome. There you go.

They recommend Typ five solder paste. so let's crack this thing open. Ah, frustration. free packaging That's pretty good and uh, that is quite neat.

I Don't actually have any uh, solder paste? Well that feels a bit that feels a bit sticky. Actually, that's not not smooth at all. I'm not sure I'm not greatly thrilled by the manufacturing quality of that I think it's built down to price. This thing's pretty cheap by the way.

I'm not uh sure exactly how much, but uh, you won't pay a fortune for this thing, but that sort of. It's bit jerky. It's sort of not a really fluid motion on no I can completely take that back. It's because it's the at the end of the travel there.

so if you depress that and put it right up here, so there's the little plunger that goes into the top of your syringe down in there and now the action is oh smooth as a baby's butt now. I like that so it gives a set distance there for your syringe. Excellent! Now, while I haven't tried this I can see, um, that one full depression of the lever really moves that plunger a long way. So 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20 So 20 depressions to get right down to the bottom.

so obviously you can't just press it once and dispense a tiny little pads worth of P paste obviously. um, it's just going to ooze it too much so you really have to give it just a gentle nudge like that probably. and uh, really? I will, um, hopefully be using this short shortly because Monday today is uh, what is it? Saturday there we go. Um I am uh, getting my thermal oven.

Um, but I'll be using a stencil I don't but I can order some uh paste stuff. so I'm getting my own Reflow oven. that will be awesome. I'm going to do my new microcurrent boards so I'll probably get some uh syringe paste and try this out as well.

Excellent! Check it out on Tindy We have one from Brian s in Tacoma Washington in the United States of America and it is absolutely tiny. Open before Christmas I Have indeed, thank you very much. It's a Christmas ornament. Brilliant! Hope it's something s again will can hang on the tree.

Oh look, check it out. We have ourselves a microcontroller flashing snowman. Well unfortunately. um, we don't get snow here in Australia Merry Christmas Um, we don't get snow because we have Christmas Here is summertime so well you know.

Oops, but hey it is cool. San will love the flashing lights I'm sure designed by Brian Shels if that's how you pronounce it. sorry Brian uh. Unic Locker 2013 Fantastic little CR 2032 Button cell there and uh, Bob's your uncle.
This thing is going to flash or do something silly. He even included thoughtfully a battery. Let's give it a go. One little thing.

I Immediately notice when you slide the battery in here. there's the LEDs exposed around here the pads and could potentially short out when you slip that battery in. Although it is one of those looks like it's you know, um, a decent height one so you can actually get it in an in an angle and slightly avoid that. But anyway, trap for young players, it's flashing.

Oh Sean's going to love this. Is that the only pattern? no I assume it change. Yeah, it's going to change. Brilliant.

There you go. I Think it just cycled through. Fantastic. And yes it is.

Open Source Hardware And the Bloody PCB manufacturers left their manufacturing mark on the board and Brian's been watching my videos and uh, stuff he learned from my videos. He's done this board so awesome and it's also available on Tindy Tocom that he learned about on the mailbag segment as well. It's got an At tiny 45 mic five IO pins soy Charlie Plex The Io to get 20 individually addressable leads designed the board to be end user assemble with through hole leads or is this one? it comes as Sbled I put surface mount leads on it, seem a bit more regularly fitting the througho pads just fine. That's interesting.

There's Js2 connector on the back to allow be power from 5 power supply when hung on a tree cuz yeah! I don't know what are you going to get? You know, 10 hours of flashing out of it? Probably something like this. Happy Holidays everyone! Yes indeed! Happy holidays Thank you very very much. Brian And this one I was also clued up that would be sent. it's from Tokyo Flash in Japan and some people may know them.

they are the purveyor of fine. uh, tacky. as in Japanese tacky. uh Watchers You know that flash and do all sorts of uh, weird and wonderful.

Uh, you know, patterns. you know, not necessarily tell the time in any meaningful way, but they uh, manufacture all these weird and wonderful watches based on user uh, user requests. So yeah, apparently like they got like a forum or something and um, you can vote for it or something. This is the Cass is that the model? I don't know.

They did clue me up and they asked me which one I wanted and uh I said oh yeah, this one will do and here it is. Oh jeez, a bit of weight in that. that's pretty weighty. That's all.

solid solid metal. So let's uh, there's backlight. Anyway, these things I'll show you the function of this watch in a second. but that's really dim.

That display. Wow. I Had no idea it would be that dim. and this model is called the Upload.

Why? Because it has a built-in USB stick built into it basically. Um, that's the reason why they called it the upload. But yeah, let's have a look at how it actually displays the time. Now this might look like complete gibberish, but it's not.
It is one of these angled display so you've actually got to tilt it on an angle which isn't really working here cuz I Need something that's uh, uh, you know the right color behind that before you can actually read the time or read it really well it's designed to be. You know, one of these optical illusion things that only really becomes good when you read in the side. H Let me see if I can work with the background here. As it turns out, this is really quite hard to get and if you turn it, it's like on, uh, camera that is.

but you can see a very narrow digits 12, 57, 51, 52, 53 and then coun it up in 100s of a second. which I really like. but yeah, sorry I can't really. You know the glare on the screen just when you tilt it at an angle that makes it readable is just and they two squished together.

It's ah, it. it's just useless. As a practical watch, it really is hopeless. But well, that's half the idea of these Tokyo flash watches.

They're not really practical. their art I guess. but uh, that's not the camera doing that that LCD is, really, you know, quite poor. In fact, it's probably showing up better on camera than what I'm viewing it here in real life.

just a little bit better for some reason. but the contrast on it straight on is just awful. but I guess you're not supposed to read it straight on. But the whole idea is that you look at the you know people can see that it's flashing over and doing some Arty farty type stuff.

right? That's the whole point. and really, the backlight is just the backlight is just. you know, it's pretty darn hopeless because it's you know, not even at all. They really need an even backlight on that thing.

so that's just that really is hopeless. So yeah, who cares about the watch, let's crack this thing open and uh, see what's inside? It's got little tiny Phillips there Ultra tiny and uh, well. I'll come back in a second. All right, let's take the take the back off single CR 20, uh 32.

There's the Um micro SD card slot down in there now I Was wondering where the USB port is on this because it is. There's the USB car, but it turns out it's can you? yeah, pull that off. It's a bit clunky and there we go. It uses a Uh TRS Jack and there's the USB to uh TRS adapter cable with it.

Oh look, it's the first watch I've ever had that comes with a screwdriver that allows you to take it apart. Brilliant. We can just leave this board out of here. I Have a uh, strong suspicion that they reuse a lot of these, uh, cases for, um, all the watches.

That's how they can. you know, spin. You know, a new version of the watch every week or every month or something like that. So there you go, we can crack that open further.
Why not? And nothing terribly exciting on the bottom side. There we've got ourselves our watch crystal 32 khz. you know, we got a transistor or a regulator, something like that, some bypass caps, and well, the surface mount contact for the battery and well, that's about all she wrote and let's take this LCD off. Of course, we're going to have some zebra strips connecting that.

there they are. They're integral to it down in there. so they got zebra strip down there and down there. They go to your pads on your PCB here and they've got a light pipe.

There you go and just a blob blob. nothing more. not that exciting I'm afraid. and there's the four side lit leads I don't know I was hoping to you know, identify the micro or something like that but n just a blob.

sorry, not that interesting. It looks like we do have a three chip solution. I mean obviously there's the uh LCD uh Driver part of it. You know the main uh part of the watch is under there just driving the you know it's it could just be a micro and they just uh, pre-program it or something like that.

um to go to all the LCD segments. So that's the Tokyo flash upload watch and it's like why I don't get it I mean Japanese and their gadgets and they you know they're obsessed with these things, aren't they? I Don't get it. Please can any of my Japanese viewers please explain the fascination with this sort of stuff? I mean it's basically unusable I mean I Why you would want this? I mean the screen is awful on it. It is absolutely awful.

the backl light's awful, and the build quality is actually not that bad. As far as you know, it's a nice heavy solid metal. got there and the uh clasp here is you know is is really quite neat I Don't mind that at all, but it's just useless I Don't get it I don't know anyway Tokyo flash I Think Got the impression that I'm some sort of you know gadget review side or something like that and they pested me to uh uh, take a look at one of these things and sorry guys I didn't get it. oops and I forgot some postcards I Know people hate postcards but hey I like get into them Ukrainian Carpathians look at that.

Excellent in the Ukraine Brilliant happy Halloween well yeah I don't I don't uh subscribe to the Halloween thing but uh yeah, thank you very much for your postcard sorry in Chur Cassie In the Ukraine Instead of a postcard, we have a hom printed picture from his own lab Marcus from Austria Austria not Australia I Saw a recent video excited how you were about a letter uh from a typewriter. How about a hand printed postcard from the dark room? Brilliant! I Can picture Marcus down in his dark room down in the basement printing out all these photos. Do people still do that? I Guess they do. Excellent Thanks Marcus.

    Why did they make the watch like that? Who thought that was a good idea??

    tokyoflash has put out one masterpiece, the retrofit.

    Those watches are intended so the owner is the only one who can read the time, due to training their eyes to perceive it at an extreme tilt?

    The keyboard looks a lot like a Casio. Could just be a coincidence though.

    Every watch I own has come with a couple of tools. Pin removal tools, screwdrivers, etc… But saying that all my watches cost around £1000 so I should they they come with their own tools to easily exchange straps and/or adjust the size of their metal straps… I'd be very pissed off if I bought a watch for a grand and then had to pay more to buy a tool to remove or add a link to the strap so it fit me correctly… lol

    those russian parts are extremely useful for fixing russian radios, swapping like for like is way easier than identifying parts.

    With regard to the watch, you can tilt your phone at the angle and it works great!

    It seems like most of electronics components that still are being manufactured in former USSR, are from nineties or even older. There are some modern ones, even some microcontrollers and that sort of stuff, but really there're just a few. We import a LOT from South-East Asia, USA and Europe.

    I think it would be possible to use some kind of metal lubricant on that solder paste press if the stickiness becomes an issue.

    There are still a good amount of people who print their own photographs- mostly B&W but colour is quite possible. There is also a community out there of people experimenting with alternate developing solutions; apparently a strong coffee solution works very well for developing colour photographs.

    That solder paste dispenser would also be quite useful for thermal paste.

    the resistors or whatever they are say MLT-2 on them

    Run a soldering iron over the connections to get a better connection with the LCD screen, it usually fixes the problem unless the LCD is dying
