38:34 This is 4-phase clock generator for the main chip. Also, I guess the VFD is OK (black stuff inside becomes white if there is air inside), try to power it up and check supply rails. 99% there is a problem in the power supply. It is very primitive, you can quickly find and fix the problem.

Hi, Dave. This is the VFD ИВ-18 (IW-18) display , and this white stuff (some kind of paint) is 100% normal in this place :) I have this display in a mint condition (it has never been soldered) and I also have a white coating exactly in this place (from the factory). I think it's a kind of protective layer, because in this place, there are two Getter rings - and as you know, these have to be inductively heated. As long as you have a black coating on the back glass, it means that it keeps the vacuum and the display should work! Take a look at the fuse, replace the capacitors maybe, etc. By the way, I must honestly admit that this calculator looks beautiful (i fell in love immediately;) ). Maybe the quality of the material from which the casing was made is not at the highest level, but when it comes to design, it looks great! A combination of white with black and green island (display) in the middle, simply looks clean and beautiful. This one beveled corner with which the power cord was lead out. Everything looks more modern than it really is;) I wanted to add that I'm not Russian :) :) Cheers!
2:49 I suspect the reason it's got dual mics is simply because it's a standard board that can be picked up fairly cheaply - the ReSpeaker 2-Mic Pi HAT.
The HP board is probably part of some telecom testing equipment. The 140MB/s rating is a standard bit rate for high order multiplex equipment which I worked on in the late 80's. The 75ohm input impedance is standard for this type of telecom equipment.
@@basshead. "it would be funny if it weren't so sad" (GLaDOS 2011). You guys probably don't get the video game reference, but it's from one of my favorite games.
The timer is just for learning and fun. I used what I got, so it's a mix of SMD and through-hole. I wish you would discuss about the calibration like how to measure its frequency and calculate its trim value. It's all in the MCP7940N datasheet and I believe people would love to see it because it's very educational.
Hi Dave!. Not sure if someone already said it. Chip on 38:35 is К165ГФ3 - 4 phase impulse generator. It have frequency range of 75-100kHz and was used in calculators.
That VFD is looking EXACTLY like it should. The white coating is to make sure the getter doesn't short out the parts it's not supposed to do. The silvering on the back of the tube is like it should be. Silver = Good. Gray/white, air got in = junk.
IV-18 is a 8-digit 7-segment VFD tube, also used in the Ice tube clock kit from adafruit. Adafruit doesn't have the kit or the tube anymore, but the tube is available on eBay. I'm sure you will check, but it sure looks like the same display. Please keep up the good work / videos. Fran and Dave
"hey Snips, would you work with my old ass analog scope?" lol, man, that thing is impressive. The calculator tube is good, it would be bad it that black stuff was white.
Dave, the black on the back of the VFD is probably just getter compound and you should look around that area for any type of getter ring or holder; the silvery streak is kind-of strange... no comment on that, but if the display still has the getter, its probably still has a good vacuum, and might be worth trying to see if it works
Dave I think the stereo microphones on the voice recognition thing are there to help with keeping original signal and echo apart. If you cross-correlate the signal from both inputs to find the timing difference, then overlay them while correcting for the difference you should get a signal with minimized echo components. at least I think so...
I was also thinking that it would improve the ability to interpret the audio through added programming. But I am a "young player" at my tender age of 43!
with dual microphones you can easily look at the side channel (or difference signal) to pick out sounds that are closer, or the mid channel (sum signal) to pick out sounds that are far away -- since the more close a sound source is, the more differently it will get picked up by the two microphones. Owsley, sound guy for the Grateful Dead, famously used this technique in order to prevent feedback from his wall of sound (which was behind the band) going into the vocal mics!
Love this logic parts always a remembering the young years hooking up this digitalis on a vero board and some fancy led´s that was the days back then. Thank´s for the video.
I tried to use snips before, couldn't make it work at all. Edit: The scope connection doesn't provide power. It's a device, so it can't. Only host can provide power. (OTG is both, kinda)
That HP board is a STM-1 (1x VC-4) SDH serial interface card of some sorts, telco stuff, my guess is that it's used to monitor the timing of the signal as it has to be pretty precise.
If the timer is in a room that you don't want bright light at night you would like the back light to turn off under is I end up having to put electrical tape over indicators and LCD screens cuz the blue light emitted will keep me awake
All the more reason to not use stupidly bright blue or green positive LCD panels. I've used red negative ones for similar projects, and they look gorgeous in dark or dim rooms.
Once I went so far as to develop a ATtiny85 based solution to be able to turn off the backlight on Ni-MH charger. Its bright display illumination was very annoying in the night.
Now that Snips project is really cool. Must have been a lot of work! I'm impressed with how well it works. Voice recognition is more often terrible instead of usable
That IS pretty cool. I personally am not so advanced in electronics to require such a device, nor able to afford the scope that will recognize the voice, but even now I find myself adjusting my voice so that Google will recognize it better when I text.
It can't steal power from the usb port because they are limited to 500mA 5V unless you use PD which I don't think your scopes have; and the RPi specs a 2A 5V supply iirc. Not that it uses it constantly but for peak usage and all the io you can attach.
That 68000 board is probably the main CPU board for the test rack. Looks very typical for CPU boards in such systems in the 1980s, including the on card interfaces for external busses.
Black stuff inside the VFD is what is known as "getter". It is there to attract and remove any stray particles to maintain as close to a perfect vacuum as possible. You'll see that on most VFDs and vacuum tubes.
That display looks fine. I have an Adafruit clock kit that's been running continuously, perfectly for 8 years or so with a display tube that looks exactly like that. In fact, the tube might even be the same part.
Wow this takes me back, i remember those IBM cards. I thought the crosshatch was more an attempt to cut crosstalk between the chips like some kind of shielding?. I love the 68000 processor, worked with them at college, and of course they were used in Commodore Amiga's. I still have a heavily modded A1200 with a 68060, yes a 60Mhz computer from the early 90's. It still works, has USB, 4 hard drives, 2 floppy, 2 CDR's and it boots up in less than 60 seconds. It even plays MP3's which wasn't even invented yet.

Dave, The Russian Calculator is labeled SPECTRONICA MKU acording to my BABEL FISH. The Babel fish is a small, bright yellow fish, which can be placed in someone's ear in order for them to be able to hear any language translated into their first language.
The two 2U Eurocard boards are most likely VME bus boards. Very common for industrial and instrument 68000 based systems of that era. The VME bus is a ruggedised standards compliant version of Motorola's VERSA bus which used less robust card edge connectors. 3 rows of pins on the connectors + 68000 screams VME bus to me. Top connector would be the VME bus, and bottom connector may have 32 bit VME expansion, and/or IO connections routed via the backplane. Routing the IOs via the backplane has the advantage of not needing to muck with cables when doing a board swap. The one with the 68000 could be a dedicated IO processor board or a full embedded processor board with limited memory. Are those 2 * 64k 150ns SRAM chips by the EPROMS? I didn't see a DRAM bank. The HP-IB bus would be for hooking up hard disks, floppies, and/or various instruments.
I have a few of those display tubes, they're the IV-18 tube. They all look like this and work fine. About 3.3V AC on the heater and -30 to -50VDC on the grids and segments should make it come alive.
I wonder how Ollie would be with a foot pedal instead of the initial "Hey Snips" voice command. It'd shave off a few seconds I'm sure. Would also remove the random triggering.
@@the_eminent_Joshua_E_Hrouda If you buy just the ZIF sockets from them, they are like $30-$45. That's a huge component cost, but $40-$55 for the rest of the board (small PCB, two tracks, two screwed-in banana plugs) is, even considering it a niche product that is maybe hand-assembled, absolutely ridiculous. Agreed you could likely 3d print (especially with a resin printer) a ZIF socket that would work for us. Not sure what tolerances they support, though.
When I visited the Soviet Union in about 1987 most shops used and abacus to add up your bill so this calculator is pretty hot stuff. Like most russian stuff simple clean and overbuilt.
"Hey snips, next video"...thanks for introducing snips to us Dave. This could be the basis for a whole lot of projects, probably not involving a cro though.
I got an Elektronika MKU _YEARS_ ago. Mine is all black. It shipped from Ukraine in _a burlap sack,_ and managed to make it the ENTIRE way to my door intact... Then it got knocked off the table by someone at my place 10 minutes after I received it, cracking the VFD... I was so furious! I was able to get a replacement for the VFD for very cheap. I think I only spent $15, so it wasn't too bad. It still blew me away that it could travel half way around the world in a friggin' potato sack, yet not survive the people I lived with at the time for 10 minutes! Now I can just laugh at how absurd that was! XD
Backlight can be hard on the regulator, especially with the relays being powered from it as well. Maybe it's annoying at night, so it turns off when you don't need it.
Interesting HP 68K board and the TTL->ECL logic interface card - from a late 80s/early 90s microwave link frame? 34Mbps and 140Mbps were standard trunk speeds for regional point-to-point networks. Early ATM sometimes ran at 140Mbps over fibre (instead of 155Mbps) This was state of the art in that frame relay/ATM era.
According to Google Translate "ЭЛЕКТРОНИКА МКУ1" or ELEKTRONIKA MKU1 just stands for Electronics MKU1 in english Apparently Elektronika was used as a brand for Soviet designs from the Ministry of Electronic Industry. Apparently Elektronika is still a brand in use today in Belarus (ALso I have a feeling that the switch for "Г" and "P" are G and R for Grads and Radians maybe?)
Dave, had you considered de-capping that 68000? The brazed lid version should be pretty easy to open up. Should make for an interesting subject to look at under the microscope!
They did two types of power input on these elektronika calculators a 42volt AC input and a 220volt AC input version this one seems to be 220v 220b for the Russian. The 42volt AC was used in schools, some classrooms had 42v AC power sockets
Well, it's a bit difficult to select some measurements on my -DS1054Z- DS1104Z, so that voice control thing might come in handy... Though some quick access buttons would also be nice.
The daughter board in Snips is by ReSpeaker, respeaker.io/2_mic_array/ not something custom to that design. I don't think they sell it a bare pcb, only complete boards.
RE 34:12 "Have no idea what that says" Hi Dave it says..... Converted from Russian Cyrillic to Latin Letters ELEKTRONIKA MKU1 Pronounced as ELECTRONICA MKU1
Dave we used dual inline packaged delay lines in the development of the early winchester drives (talking about 16" platters ). They also where tapped by the pins. However their characteristics were crappy to say the least. The best is still a proper terminated piece of coax cable.
You'll also see the DIP delay lines in a lot of older (e.g. 4116/4164) DRAM designs to provide the delay between RAS and CAS on the multiplexed address lines.
The HP 68000 board and cousin look like part of a VME bus system. I used to use a broadcast character generator that was a Motorola branded 68020 VME card with the same DIN connectors on the back and the aluminum front. It was in a large chassis for the video raster processing with a bunch of custom boards. It was called a Chyron Infinit! (exclamation mark was part of the name :)
That DSKY T-Shirt is soo cool. One of Fran's best work. About the timer board, the backlight timeout is a nice option if you want to limit light pollution at night. But, yes, it would be nice to have the option to choose in the setting menu. The buzzer probably sounds a bit sick because you didn't remove the sticker.
I would love to see a Scotsman try and use the oscilloscope voice control. There is a brilliant youtube video of one trying to get his car to understand his accent and failing. BTW, good luck understanding it as well, totally incomprehensible..
Hey Dave! I enjoy and appreciate your videos. Some of the stuff you are sent in the mailbag series is simply amazing! On the Russian display...I think the stuff that had the silver color at the one end may be like a getter in a vacuum tube and it probably has lost the vacuum...which would explain the reason it doesn't seem to work. I am curious what that part would cost and if it would be worth your time and expense to replace it and check the device out to see if it would work with new display device?
The HP digital card appears to be a video digitizer and usually it's stream would be muxed in with many more in a fiber cable channel and demuxed out at the destination. (fiber ring) Usually the A-D clock rate would be three times the color frequency. The calculator's display silver is indeed the getter in that vacuum tube. It is a shame that he didn't test the fuse and if good measure the power supply's output Voltage. (should be two: for the logic and for the tube {? 20 V. ?} )
Do you actually have to wait for the lights to go on after saying "Hey snips" before saying the command or could you just say it in one sentence? Could make the delay a bit smaller!
You know you can get a 7 day timer with multiple setpoints per day for like $10 from eBay. 😉. That has din rail mount and is tiny - I keep a few handy for all sorts of things - easy to program too. Not sure why this one was developed when there are so many out there. Needs to be 5 to 32 volt power as well to be of a wide usage item too.
MCU is probably toggling the buzzer pin with timer interrupt. I've seen that many times before. If you want a pure buzzer sound it has to be driven by hardware timer output compare.

Hi, Dave.
This is the VFD ИВ-18 (IW-18) display , and this white stuff (some kind of paint) is 100% normal in this place :)
I have this display in a mint condition (it has never been soldered) and I also have a white coating exactly in this place (from the factory).
I think it's a kind of protective layer, because in this place, there are two Getter rings - and as you know, these have to be inductively heated.
As long as you have a black coating on the back glass, it means that it keeps the vacuum and the display should work!
Take a look at the fuse, replace the capacitors maybe, etc.
By the way, I must honestly admit that this calculator looks beautiful (i fell in love immediately;) ). Maybe the quality of the material from which the casing was made is not at the highest level, but when it comes to design, it looks great! A combination of white with black and green island (display) in the middle, simply looks clean and beautiful. This one beveled corner with which the power cord was lead out.

That's a huge component cost, but $40-$55 for the rest of the board (small PCB, two tracks, two screwed-in banana plugs) is, even considering it a niche product that is maybe hand-assembled, absolutely ridiculous.
Agreed you could likely 3d print (especially with a resin printer) a ZIF socket that would work for us. Not sure what tolerances they support, though.
When I visited the Soviet Union in about 1987 most shops used and abacus to add up your bill so this calculator is pretty hot stuff. Like most russian stuff simple clean and overbuilt.
Fran is a rockstar.
"Hey snips, next video"...thanks for introducing snips to us Dave. This could be the basis for a whole lot of projects, probably not involving a cro though.
I could see the voice command module being very helpful for those without the use of both hands
I got an Elektronika MKU _YEARS_ ago. Mine is all black. It shipped from Ukraine in _a burlap sack,_ and managed to make it the ENTIRE way to my door intact... Then it got knocked off the table by someone at my place 10 minutes after I received it, cracking the VFD... I was so furious! I was able to get a replacement for the VFD for very cheap. I think I only spent $15, so it wasn't too bad. It still blew me away that it could travel half way around the world in a friggin' potato sack, yet not survive the people I lived with at the time for 10 minutes! Now I can just laugh at how absurd that was! XD
Backlight can be hard on the regulator, especially with the relays being powered from it as well. Maybe it's annoying at night, so it turns off when you don't need it.
Interesting HP 68K board and the TTL->ECL logic interface card - from a late 80s/early 90s microwave link frame? 34Mbps and 140Mbps were standard trunk speeds for regional point-to-point networks. Early ATM sometimes ran at 140Mbps over fibre (instead of 155Mbps) This was state of the art in that frame relay/ATM era.
According to Google Translate "ЭЛЕКТРОНИКА МКУ1" or ELEKTRONIKA MKU1 just stands for Electronics MKU1 in english
Apparently Elektronika was used as a brand for Soviet designs from the Ministry of Electronic Industry. Apparently Elektronika is still a brand in use today in Belarus
(ALso I have a feeling that the switch for "Г" and "P" are G and R for Grads and Radians maybe?)
Dave, had you considered de-capping that 68000? The brazed lid version should be pretty easy to open up. Should make for an interesting subject to look at under the microscope!
They did two types of power input on these elektronika calculators a 42volt AC input and a 220volt AC input version this one seems to be 220v 220b for the Russian. The 42volt AC was used in schools, some classrooms had 42v AC power sockets
hey snips: open the lab door. ''Im sorry dave, im afraid I cant let you that''
Lol
I feel like Mr. Snips (Ollie) would still be useful for non time critical functions at the very least, yeah?
You got the dsky t-shirt, I'm so jealous
"What's on channel 2?"
Sounds like something my Dad would've asked me when watching tv!
Fran is amazing!
Well, it's a bit difficult to select some measurements on my -DS1054Z- DS1104Z, so that voice control thing might come in handy... Though some quick access buttons would also be nice.
The daughter board in Snips is by ReSpeaker, respeaker.io/2_mic_array/ not something custom to that design. I don't think they sell it a bare pcb, only complete boards.
Hong Kong SAR has recently been renamed to the original SAR abbreviation

МКУ1 means - micro-calculator universal (model 1)
RE 34:12
"Have no idea what that says"
Hi Dave
it says.....
Converted from Russian Cyrillic to Latin Letters
ELEKTRONIKA MKU1
Pronounced as ELECTRONICA MKU1
Those zif sockets for your multimeter are $85. You can buy tweezers with banana plugs for $7 on Amazon.
Was it too hard to just plug the calculator in to see if it works?
36:00 I think that’s the “Getter”. Normal in vacuum tubes.
I LOVE FRAN ! Nice shirt .
"Ya got your tongue at the right angle." Yeah. This is literally the key to board work and exploration.
Dave we used dual inline packaged delay lines in the development of the early winchester drives (talking about 16" platters ). They also where tapped by the pins. However their characteristics were crappy to say the least. The best is still a proper terminated piece of coax cable.
You'll also see the DIP delay lines in a lot of older (e.g. 4116/4164) DRAM designs to provide the delay between RAS and CAS on the multiplexed address lines.
Started talking to your scope, eh? That's a bit...disturbing :)
Especially the idiotic start phrase "hey snips".... errr, WTF?
The HP 68000 board and cousin look like part of a VME bus system. I used to use a broadcast character generator that was a Motorola branded 68020 VME card with the same DIN connectors on the back and the aluminum front. It was in a large chassis for the video raster processing with a bunch of custom boards. It was called a Chyron Infinit! (exclamation mark was part of the name :)
Wou, they should definitely include this "ships" thing into the scopes :) like it so much!
I think old HP Infiniium scopes (ones with Windows 98) had voice control, never tried that though ;)
That DSKY T-Shirt is soo cool. One of Fran's best work.
About the timer board, the backlight timeout is a nice option if you want to limit light pollution at night. But, yes, it would be nice to have the option to choose in the setting menu.
The buzzer probably sounds a bit sick because you didn't remove the sticker.
display is fine, silver thingy is the getter compound, vacuum is ok, and the unit is probably an easy fix
I would love to see a Scotsman try and use the oscilloscope voice control. There is a brilliant youtube video of one trying to get his car to understand his accent and failing. BTW, good luck understanding it as well, totally incomprehensible..
UA-camr DiodeGoneWild has a good voice to test this device.
DSKY should show "Alarm 1202". (All task slots are occupied -- Force Restart)
Hey Dave!
I enjoy and appreciate your videos. Some of the stuff you are sent in the mailbag series is simply amazing!
On the Russian display...I think the stuff that had the silver color at the one end may be like a getter in a vacuum tube and it probably has lost the vacuum...which would explain the reason it doesn't seem to work. I am curious what that part would cost and if it would be worth your time and expense to replace it and check the device out to see if it would work with new display device?
Lol I'm impressed that Dave uses such an unwieldy knife video after video; box cutter is so much more convenient
Good work Fran!
The HP digital card appears to be a video digitizer and usually it's stream would be muxed in with many more in a fiber cable channel and demuxed out at the destination. (fiber ring)
Usually the A-D clock rate would be three times the color frequency.
The calculator's display silver is indeed the getter in that vacuum tube.
It is a shame that he didn't test the fuse and if good measure the power supply's output Voltage. (should be two: for the logic and for the tube {? 20 V. ?} )
That VFD is a thing of beauty all on it's own!
Do you actually have to wait for the lights to go on after saying "Hey snips" before saying the command or could you just say it in one sentence? Could make the delay a bit smaller!
You know you can get a 7 day timer with multiple setpoints per day for like $10 from eBay. 😉. That has din rail mount and is tiny - I keep a few handy for all sorts of things - easy to program too. Not sure why this one was developed when there are so many out there. Needs to be 5 to 32 volt power as well to be of a wide usage item too.
MCU is probably toggling the buzzer pin with timer interrupt.
I've seen that many times before. If you want a pure buzzer sound it has to be driven by hardware timer output compare.
28:30, definitely laid out for minimum cycle time on auto insertion.
Perhaps the delay lines allow tuning the card for its position in the rack?
Did you try instructing the oscilloscope to open the pod bay door?
Snips would be great for anyone with a one arm disability. Very surprised at how good voice recognition is getting.
100SteveB Also for anyone with two probes and lack of a third hand.
@@johnfrancisdoe1563 No kidding. I have lost track of how many times I have written "make 3rd arm" on my todo list.
Hehehe...Cool... So cute device!!! Bravo Ollie!
cut a squar out a piece of paper. Stick cellotape on it. turn the paper and place your smd part on the cellotape and you can use normal probes or tweezers without the risc of flying parts.
Hope your feeling better soon.
Love the thumbnail! "Do not drop", yeah, but it doesn't say do not kick!
