[@RinoaL]

the LCD's plates are seperating. i had a multimeter that did that. put a paper clip or something on it and it should keep both sheets of the screen contacting.

[@xjet]

They offered to send me one of those watches too but I didn't bother taking them up on the offer. Looked pretty lame right from the get-go so thanks for saving me the time of coming to the same conclusion.

[@electronalchemy7513]

I reckon that is a standard calculator chip, and they are passing the information over from the meter chip not by serial link, but by faking key presses! Kudos to Hioki for providing support for equipment that is 32 years old. Gives you some confidence in buying their current products.

[@EEVblog]

Yeah, maybe that's what the 2nd chip is for. It would be serial interface to that top PCB and chip though from the DMM chipset.

[@CookingWithCows]

Haha by the looks of it there was much more stuff in the russian package before the russian authorities opened it and sealed it back with their blue-white tape :P

[@arcadeuk]

Was anyone else screaming at their computer "Dave.... Dave...... DAVE.... There is an ON and OFF button for the calculator" :)

[@electronicsNmore]

For a 32 year old DMM/Calculator, it was certainly nice for back in that time. Funny how we look at things from years ago, and compare them to things we have today. There is really no comparison, even though I have seen far worse electronic devices in 2013!

[@Polaventris]

I wonder why they didn't design the dispenser with an adjusting screw which would limit how much you can depress the handle to dispense certain amount of paste at one press.

[@PieCo]

Seller here - such a design change would actually greatly increase the cost, and it'd make the device less suitable for use across a variety of materials and dispensing tips. Moreover, it really isn't needed - fingers works rather well for such things :)

[@Keith_Ward]

***** Agreed. An metering adjustment screw could be easily placed in several places. However in the sloppy corporate world these costs have to be greatly inflated due to "redesign" and "retooling" to do such. And of course several executives have to be given a bonus for one reason or another. All of this has to be passed off to us ... the unfortunate customer.

[@electronicsNmore]

The Russian parts actually look like quality parts.

[@SaberusTerras]

They look rather bulky to me, but that might just be the Soviet way of making sure the parts are rock solid and will last a lifetime, not fail after 3-5 years like some modern 'planned obsolescence' crap.

[@electronicsNmore]

They do, but these parts were made in the 80's. Back then, everything was bigger, even the USA made bigger components..

[@maximilianmustermann8172]

Saberus Terras well I'm not really "in the field" but isn't that capacitory very weak? And also: where do you have the place for such giant capacitors on say... A "modern" Computer Mainboard? I paid a little more for my mainboard, so that I had "guaranteed quality and tested caps and other components". The caps last at least 10.000 hours at 130° (I might be wrong there) and under normal usage conditions I guess that that board will server be for far more then 5 years. After that time span there will be new hardware anyway because development still goes pretty fast in this sector.

[@YuriLM]

This Oleg (Олег) must be ashamed of him self! He could find something more interesting rather then just a few caps and resistors. At least those could be from 60-s era.. OK, I had a few nixies somewhere and broke soviet "home pc" from late '80. Might suit for tear-down. So keep tuned :)

[@GytisGG]

They might look like that, but in fact these are very poor quality parts. The only good Russian (soviet) electronics parts were made for army purposes. These parts here were used in household items like tube TVs, and they were extremely unreliable. The quality of soviet electronic devices and components were better the further from Moscow it was: Say Latvian or Lithuanian devices were of a better quality, but compared to Japanese counterparts - complete rubbish.

[@Razor2048]

Does the screen get any more visible if you run like 4 volts into the device? (if not, then try 240 volts :) )

[@ClosetYeti]

I get giddy whenever I see this in my sub box. Well, anything from the EEVBlog, really. *high five*

[@mariuslambacher8743]

The design of the bug cap was quite common here in germany as well; there was often a metal ring with the second wire soldered on and fixed with a plastic washer

[@TheChipmunk2008]

I kinda like the postcards, it doesn't take much time and lets you acknowledge more viewers who send you stuff :)

[@ChrisGammell]

The tilt is because the resistive juices inside are sloshing around

[@bgdwiepp]

By his great noodly appendage! Chris is watching one of Daves videos for once!

[@寇磊磊]

The product design is so good, I like this product , regardless of the distribution from the circuit , and product quality are my praise , great.

[@yucannthahvitt]

The darkroom is a dying desire since digital has become the superior solution for almost all photographers. Good on you, Markus.

[@z1power]

By the way, props up to the Russian guy who sent the short note. It was one sentence long and said everything that needed to be said. No need to write entire novels like some mail bag folks!!

[@riffraff60]

personally, I love the postcards, and so does everyone that sends one...

[@randomviewer896]

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

[@KOTR2003]

:o! I was looking for a solder paste dispenser like that months ago but only found a supplier in the UK. Have to buy me one of those, much better than the pistol style dispenser.

[@seeindarkness]

Those USSR trimmer pots are very precise, you can calibrate it to a very accurate value using the screw.

[@ExtremeMetal]

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

[@PeterCCamilleri]

A quick look at the "bodge" SIP resistor reveals that they are all different values. This perhaps, explains why they did not use an off-the-shelf SIP. Maybe?

[@z1power]

Notice almost all those soviet parts were marked with a K or an M. The K parts were for civilian use, the M parts were rated for military. Virtually all soviet electronic parts had these markings.

[@abpccpba]

Dave; weak LCD, I have read that heating the LCD to a ?(forgot the actual temp.) temperature the liquid crystal will fill the whole screen. When it cools to room temperature the liquid will move back to its normal places and may repair unit.

[@BrekMartin]

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

[@LevonAvagyan]

Hi dave, You can use circular polarizer filter to remove this glare. Ask Google for picrures with and without circular polarizer.

[@alextrofimov7947]

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.

[@GregoMorgan]

That's the best watch you can get as long as you don't ever need to know what the time is.

[@zaidhussain5206]

Hi Guys Most of the Russain components in this video are previously used in old generation weaponry systems like Sam Air defence systems

[@lasersbee]

FYI.. For the Solder Paste Press.. it costs $49.99USD plus shipping :EEK: From your video it looks like it should be more in the $10-$20 range.

[@PieCo]

@lasersbee That's funny :) Here's the next cheapest tool on the market: www.digikey.com/product-detail/en/SMDSG10CC/SMDSG10CC-ND/2515687 Oh, and you need to replace the plungers on that unit fairly often, so make sure to find a pack of those. I think that they're around $25.

[@lasersbee]

***** Ha Ha...You're paying way too much for a spatula...;) I was actually just referring to the comment by Dave in the video at ~23:40 of the Press being "pretty cheap". For about double that price I can buy a Solder Paste Dispenser like eBay Item #160982115243.

[@PieCo]

lasersbee Of course, you might want to mention that your eBay bargain requires an air compressor and fittings - so you'll be at at 6x in the end. Just sayin'.

[@lasersbee]

Pieco Not trying to downplay your product... On the contrary we just bought one this morning shipping to Quebec because we could afford to try it out. We'll see if it works for us or if we need to invest a bit more...

[@PieCo]

lasersbee Funny, I noticed that :) I'll toss in an extra goody for you to play with.

[@armilarzifferblatt9751]

Anyone knows the technical name of the "zebra strips" conductive material? Great to watch as always!

[@superdau]

Well, they actually ARE called "ZEBRA" connectors/strips. It's a trademark.

[@douro20]

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.

[@NekitaNet]

A silly question EEVblog But... Is the Pico Paste Press perhaps compatible with Thermal Paste for nice dispensation for a cooling block and cpu...

[@electron-1979]

What was the mysterious jumper link for?

[@redtails]

33:15 bloooooob

[@muh1h1]

the reason why the watch has such a poor contrast when viewed from above is, because it is designed to be read from a very tight angle! :)

[@alnonymous9361]

the 754 is a very accurate multimeter and it has a built in calculator

[@MikeStavola]

bad polarization filter on the hioki

[@gamccoy]

That was a Mailbag segment with two bonus tear downs. I approve and endorse this BLOG.

[@GaRbAllZ]

Mike always finds the neatest gadgets....

[@PlaywithJunk]

Use it for thermal paste on CPU's or transistors.... :-)

[@BersekViking]

I guess they are just reading the keyboard scanning and simulating keypresses when you transfer the meter reading to the calculator.

[@gamerpaddy]

whats in this SD card (at the watch?)

[@douro20]

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

[@rich1051414]

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?

[@skizgrzl]

something tells me that tokyo watch has a contrast adjustment, or the battery is low. surely that dim and hard to see display as shown in this video wouldn't pass their QC, but who knows. that thing looks a bit too large to wear, but some people like big watches.

[@edwardLongman]

Hi Dave, Great videos! Just wondering what the SD card in the watch is for? is that how they're programmed?

[@Ucceah]

tokyoflash has put out one masterpiece, the retrofit.

[@dtiydr]

12:25 Nope, high precision 8.99 Ohm resistor.

[@1337Shockwav3]

Seeing how excited Dave gets about russian parts, I guess it's time for me to send something (especially since I quite enjoy this channel since over a year). I do have 2 (broken) russian/udssr made chips both in a partially interesting package.

[@luzrain]

What flash drive doing inside a watch??

[@MrBananapie89]

+EEVBLOG Tokyoflash Japan is a Singapore company not a Japanese company

[@DavidTelesPortugal]

After seeing the digits in an angle my brain can distinguish then every time now :P Awesome

[@redtails]

35:35 In fact, millions of scientist from around the world use darkrooms for developing films for western blotting.. Crazy technique, but very powerful

[@PedanticProfessor]

So you didn't notice the off and on keys on the calculator panel?

[@dhpbear2]

8:00 - that shield is to protect from DC sunspots! ;)

[@JackHalkabar]

that combo calculator is awesome, I want one!

[@DjResR]

MLT-2 - 2W resistor 1,5R = 1,5 ohms. K50-16 pretty useless capacitor, K50-35 is better, trimmer is 680 ohm, SP5-2M is a part number.

[@francistheodorecatte]

the liquid crystals probably are losing their polarization from age/shock, so you can only see them working from specific angles.

[@evghenim1955]

Maybe you just need to change the battary on the watches?

[@icpart]

The name of russian sender is Oleg Nikolaevich and first is weight 0.3kg and second is value of 100RUB. Also "набор радио детали" means electronics components kit. The first resistors are MLT-2 type. I someone interesting i found that site www.sovtube.com/en/content/3-metal-film-resistor

[@IIGrayfoxII]

I love the designs of tokyoflash watches.

[@FaSMaN]

Never even seen those solder paste pens, here in south Africa, would have to hunt one down...

[@krcptvit]

Most of ours(russian) ended up sold. They not making electronic components.

[@Doom2pro]

Possibly the funky back of the LCD is a solar cell for the calculator?

[@Cobalt-Jester]

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

[@GeorgeGraves]

So close, but so far!!! Would have been an awesome product.

[@Noah-iv2vs]

How many GB?

[@dhpbear2]

That CALCU Hi TESTER is totally OHL!

[@TheSolarShed]

What? We make that solder paste dispenser here in South Africa?! The more you know... Yay for SA! ^-^

[@alynicholls3230]

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

[@tarassu]

B is really V in russian. so 250B is 250 volts max.

[@tra757200]

Love postcards!

[@GertvandenBerg]

Hmm.. Pieco paste press made in South Africa... Looks like a rebranded Magnum MD100, which I really like...

[@AshenTiger]

I love the Russian 'Australia' underneath the address, haha!

[@franklinfrankerson]

I would love to watch that multimeter explode.

[@supyrow]

it is for viewing with half closed eyes.

[@epremeaux]

Sea Hope makes better watches. Not sure the whole story, but they were a close business relationship, and now that TokyoFlash website is closed, the SeaHope shop sells some of their products. If I remember correctly from talking with the owner of Sea Hope, they were a friendship rivalry, if not even the same company? Tokyo Flash is much more 'artistic' while Sea Hope was more.. geek/cyber, and slightly more practical.

[@redtails]

22:37 hmm. the design has clearly been taken from one of those larger glue dispensers for glueing wood and shingles XD..

[@williefleete]

how big was the SD card?

[@CaelThunderwing]

a quick google search shows it was a 2GB MicroSD.

[@ilanmagen]

The best is getting better. nice video.

[@ljmike1204]

i want that snow man to cant wait on a rgb version :)

[@devilmastah]

Why doesnt a modern multimeter have that

[@fudgesauce]

Dave keeps saying "Pee-ko", but "Pie" is right next to a pi symbol. I haven't heard of the company, but I imagine it is pronounced "pie-ko".

[@寇磊磊]

I like this product because it is so well they and practical

[@FonZ4590]

You can say whatever you want about that thing but this still works after a 100 years. or so :) the cheap shit we make now does'nt last a couple years almost.

[@Q8Police777]

Lmao you just crushed their hopes and dreams with that watch x)

[@valdasaa]

149$ for useless watch ?:D come on ... and i hate digital watches. I like old analog stuff :) with dials and stuff :) i just bought seiko titanium solar, but still dreaming about vintage Britlinger with curved glass ohhhh :D by the way you got it right wit russian rcl components :) Om - ohm and мкФ - mF ;) and there were 15 republics in ussr :) hi from one of former ussr republic Lithuania :)

[@adamramage6858]

we should just send you heavily taped up boxes and watch you struggle to un box things

[@aqualung2000]

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

[@rubusroo68]

love the xmas tree leds!

[@stupidystu]

Mailbag, not everyone's favorite.

[@bakupcpu]

hahahah the smell parts hahaha! why do we all do that I wonder :P great one!

[@charistiaanharmse301]

Woo South Africa

[@masterviper420]

Hi question how much would u se me fhe watch I kinda like it

[@SolidCoreBlack]

he called memory card a bypass caps😑

[@chaos.corner]

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

[@akkudakkupl]

Some one hit that LCD. Hard.

[@TechnoDelta]

i like that snowman :D

[@GoldSrc_]

Those Russian components were really interesting.
