Inside a soviet ionizer from 1990 (with schematic)

Such an odd thing. Very similar circuitry to a classic needle ioniser, but uses a long linear emitter wire instead. The circuitry has a nice soviet feel to it, with very chunky Russian components that seem a bit retro compared to UK ionisers from the same era.
Ionisers are blighted by a history of bad marketing that makes bold claims of being "air vitamins", and implies that the units will resolve many health conditions. In reality, the main function of ionisers is to put a charge of electrons into the air like static electricity, causing airborne contaminants to precipitate to grounded surfaces like walls and floors.
The classic desktop ioniser makes a huge mess due to the contaminants in the air settling in its vicinity. Many people stop using them because of the apparent mess they make, without realising that it's there because the unit is doing its job.
They are best suited to smaller areas with low air throughput, are silent and use such a low amount of power that they effectively cost nothing to run.
I'd guess one of the main advantages of the Ryazan 101 ioniser is that it's long emitter is far enough away from walls to precipitate that dust out in a more subtle manner.
Incidentally, the ioniser PCB of my own that I showed is now a free PCB at JLCPCB (Not a sponsor.) Note that it is only suitable for 220-240V countries though.

It seems appropriate to mention it here since it was inspired by the Chizevsky ioniser and can be used as the power supply for the "Russian Nuclear Corporation" ozone generator. (Produces very low levels of indoor ozone that emulate natural outdoor levels.)

This has such a lovely retro look, very 1950s, from when they literally just soldered all the massive (oft hand made) components together, sometimes they didn’t even use a board. its refreshing to see something so different. Cheers Clive.

[@greenaum]

Looks a lot like the chunky old phenolic they used to do on stuff in the '70s, CHEAP stuff in the '70s! I'm thinking of old Radofin / Acetronic consoles in particular. Something about single-sided PCBs maybe, or maybe both those things are just a result of primitive manufacturing at the time.

[@IgnatSolovey]

Actually 1960s. 1950s designs were a bit different, particularly in the USSR. Also, a household air ionizer in 1950s, particularly in the earlier half of 1950s... well, no. That doesn't change the fact that in the USSR (and Russia) 1960s, 1950s and even 1930s designs were in production well into 1980s and 1990s without even the slightest facelift, and sometimes there are things that are still made like 60 or 70 years ago even today, in 2023. For instance, one can get an set of enameled steel cooking pots (or a chamber pot with a lid) with (or without) flower decals that look precisely like in the days of Gagarin's flight or Caribbean Crisis. Or even earlier. The factory in the town of Lys'va, Perm Krai (north-east of the European part of Russia), uses German technology from the early 1930s, albeit slightly improved, so that the enamel in question is of really high quality and original composition... Which indeed is a testament to brilliant chemists and engineers of Weimar Republic... While there is a heft of gloomy sarcasm in my words, it's not 100% sarcasm (as much as I wish it to be).

It was absolutely normal to have the full schematic and part numbers in the manual in the SU style devices. They were meant to be user repairable and most of the population got higher education including many electronics courses. So "tinkering" with your devices was absolutely normal.

[@uln6270]

This was the norm as electronic products were constantly in need of repair due to the low reliability of components. Reliable components used for the military equipment. There were few repairmen, and the variety of equipment was large. So customers brought equipment for repair along with electronic schematic.

"220V" was specified because, in fact, USSR actively used THREE voltages through majority of its history: 110v, 127v and 220v. 110v was in train sockets, so «train-portable» things like an electric razors often had this as switch/screw dial. It was also used in some *very* old houses, causing a huge pain in the ass to their inhabitants. 127v was all-USSR standard until late 60s, when it was slowly phased out with 220v. Very slowly, in fact, last house in USSR was switched to 220v as late as 1990 (even in Moscow this process was finished only in 1986). Rural areas sometimes used 127v way in late 90s to early 2000s, if they were not connected to grid and used their own GOELRO-era equipment for generation and distribution of power. And 220v is a common standard we all know. USSR decided to switch consumer voltage to allow more current per wire, thus allowing for new and fancy stuff like electric kettles, electric ovens, et cetera, as well as saving on metal on countrywide scale. So, specifying input voltages when impossible, and putting voltage selector when possible was a must. Like, a fragment from a TV instruction of the era: >>>Before connecting the TV to the mains for the first time, you must do the following: a) check whether the fuses correspond to the actual grid voltage. At a voltage of 220 V, the fuse should be at 3 amperes; at a voltage of 127 volts, at 5 amperes; b) put the input voltage switch in a position that corresponds to the grid voltage in your apartment. Televisions are manufactured from the factory with a voltage switch set to 220 volts.

Supply voltage standardisation is a surprisingly recent thing all across Europe though. 220/380 V 50 Hz had been more or less agreed upon as a standard for new supplies by the end of WWI but existing grids had all kinds of odd setups. Edison DC (often 220/440 V) was used well into the 1960s in well-off city neighbourhoods (the ones that were first get electricity) and AC conversions often tried to make do with the existing three wires (+, - and centre/neutral) using 127/220 V systems with no neutral supplied or split-phase 110/220 supplies. On top of that there were some 127/220 V supplies with neutral and some oddball 150 V supplies. Belgium and Norway still have extensive 230 V three-phase networks and apparently so does Italy. I think Germany removed the last leftovers in the Berlin area less than ten years ago. Norway even has an IT supply with local earth, which is less than ideal as soon as there's a fault somewhere because the IT turns into a TT with dodgy earthing. 50s valve radios could usually run on 110, 127, 150, 220 and 240 V, some AC-only, others AC/DC.

From what I heard, despite that fact, there was basically no "true" way to buy spare parts so from what I've been told, Soviet electronic magazines offered tips to fix common devices and also DIY ideas listed cheap devices (usually radios) where you could source the required components.

The guys there did everything, from rewinding transformers to changing components. And there were a lot of these shops in the cities. Pretty much all electronics were mainly analog. And in the user manual you always had schematics, usually with values and sometimes even oscilloscope curve pictures on some TV or radio equipment for easy troubleshooting.

127 volt was the standard mains voltage in Russia well until 1960s, before they finally upgraded it to 220.

Hi Clive, this is an interesting video. The way that neon is mounted is something I have seen done in some old Phillips transistor radios made during 1950s.

The booklet is cool as well and an overall neat design.

[@gvii]

I was half expecting a microphone and transmitter circuit in there. On a more serious note, it's in surprisingly good shape for its age. Even the cord looks nearly brand new. I really do enjoy that extremely retro look of the board and components of that era. Old Soviet Geiger counters are really fun to crack open as well. All that hand routed and soldered wiring and whatnot is just extremely visually interesting. It's like opening something western from the fifties or sixties, only in better condition due to the fact its decades newer. How likely it is to still be functional is a whole other matter, but they're still fun to look at.

[@ayebraine]

It's new, as I gather. It's a leftover production thing (manufactured for lack of new products from a given factory), BigClive says it was manufactured in 1990. It's of course horribly outdated and quaint even for the USSR for 1990, but this is the point, it's an ionizer, an extremely cheap device sold for quite a bit more than it's worth, made on equipment/expertise that hasn't been updated in forever. In the early 1990s, various alternative medicine and quack theories were beginning to enjoy a rage following in USSR/Russia (for all the novelty, the newfound ability to build/promote/purchase them, plus the uncertainty of the times), and tons of defense factories switched to ineptly making random consumer products (called "conversion"). So the amount of crude quack products that look/are built like a military radio crossed with a dirt-cheap 1970s hotdog cooker went through the roof. The plug is a cheap plug indicative of late 70s - 80s for the simplest appliances, the style of decorative platic molding is characteristic of cheap products from late 70s, etc. Sort of like basic cheap utlility stuff from Aliexpress like travel water boilers, hasn't been updated because for the price, it still kind of sells.

Soviet household appliances were very peculiar. For example, metallic mercury was often used in such devices. I remember back in the 80's we had an ultraviolet emitter called the Photon (Фотон) which contained a quartz glass sphere surrounded by a coil. Inside the sphere was a drop of mercury. When the device was turned on, mercury evaporated and ionized under the influence of high-frequency currents. The device was used for tanning. I also still have a doorbell called Moscow (Москва). Inside there is a glass capsule with mercury, where contacts are inserted. The capsule is connected to a lever, and the lever is controlled by a magnetic coil. When the button is pressed, the coil attracts the lever and the mercury moves, randomly closing and opening the contacts. Including the circuit that controls the coil. Another lever is also attached to the coil, which is connected to a hammer that strikes a metal plate. As a result, when this doorbell is activated, it makes very unusual sounds.

[@bigclivedotcom]

We also had UVC mercury tanning lamps in the UK with heaters as ballasts to limit the current and provide infra red heat. You can still buy mercury switches on eBay. The old mercury switches were extremely reliable. I like the idea of the random bell.

[@hikewomeat]

Once I had read an article about the use of ionizers in the journal for gardeners to control the local climate. Their design was given there. Pyramids were built from wooden bars. They were wrapped spirally with a wire connected to a voltage source of 30-100 kilovolts. The diameter of the base of the pyramid is about 1 meter, the height is the same. Allegedly, these devices are able to create an ascending stream of ions, which leads to the condensation of water in the atmosphere and causes rain. They were recommended to be placed along the perimeter of the garden.

@@fiatlux4058 Now this is definitely not known, but perhaps the Egyptian pyramids had a similar purpose. Maybe they were also used to regulate climate? So we can explain traces of water erosion on the sphinx. Of course, the size of these pyramids is much larger than those described in the journal. Accordingly, the area of influence was also larger. It is clear that if the pyramids were wrapped in copper wire, then ancient people took it for their needs, just as they removed the facing stone. Strange corridors and gallery inside the pyramids could serve to accommodate sources of electricity and high -voltage converters. They were also plundered in antiquity, since there probably was a lot of metal, which then had very high value.

Unlike the states where most household electronics operate on 120v, whereas appliances typically run on 220V like dryers and electric hobs. Washing machines are usually 120v. In industry,the voltages can be 220 or 440v single or three phase. I'm sure you already knew this, Clive.

This is the same here in Canada. Higher consumption devices are 220v like heater, dryer oven and water heater. But the plug in the wall are usually 120V/ 60HZ. Except if you live in a remote area like I do. It's still 50HZ but in cities and normal places it's 60HZ. It doesn't matter much.

Everything in the USSR came with the full schematic: televisions, radios, tape recorders, record players... you name it. I've even seen schematics in instruction manuals for soviet made landline phones. Talking about the board material: it's more than likely a paper laminate, something similar to getinax. These boards are horrible, the traces tolerate no heat at all. The coper delaminates if you even look at it wrong, let alone try to do something with it. Regarding the diodes: some of them are probably have the markings on the bottom. That's the peril of using square body diodes with color markings on one side. It's true that the diodes look chunky, but that doesn't say much about the actual semiconductor crystal inside. The leads are also flat, so that's more of an appearance thing. If you flatten the leads of 1N4007 you are going to get something more or less similar. Actually there are also soviet made transistors with flat leads as well. One example is the iconic general purpose KT315 / KT361 complimentary transistors. They look weird, but are almost a direct substitute with BC547 / BC557.

Usually, but not always. Due to no IP rights for consumer equipment the owners were allowed or even encouraged to repair stuff themselves. Finding parts could be a serious problem though.

@@noop9k Schematics sometimes didn't have a later modification to the design of the device included, but one could still figure out what's going on, trace a problem, and repair it.

They were even helpful enough to tell you what voltages and what signals you should measure at the test points of the board. True, sometimes the print quality was bad, but it was still better than not having a schematic. Having said that, nobody says one can't repair a device without a schematic.

Thus the schematic included, and things like fridges that you still find running, despite being a half century old, but still in use and working well. Also standardised parts in a lot of things, so the use of capacitors, resistors and such that were designed for military use. The flat lead diodes are simply because it is easier to make, you start with a long flat strip and punch the strip to make the 2 sides, and then assemble the diodes between the flat sheet ends, solder the die to them, and then use a mould that pressure encapsulates them. Then trim off the strip joining the 2 halves for recycling, and you have the diodes. You can leave the strip on for bulk orders, making them possible to store in a reel with ease as well. just have to test each one before use then.

Very interesting! I rather like the decorative city skyline on the front. I remember we used to have an air filter that had a nice, hefty filter cartridge attached to a fan, with a pair of similar-looking carbon fiber ionizer... uh, things in it in the path of airflow, many years ago. It seemed to work, judging by all the dust the filter cartridge collected, but it suffered a misadventure at some point, and so it is no more. It is interesting how some Soviet electronics were built with pin-for-pin copies of "Western" electronic components, but others look like they are from an alternate history entirely, with big, bulky, atom-punk sort of components, all at once overbuilt and yet (from what I've heard, especially when I was younger) remarkably unreliable. I wonder if including a schematic was less as a statement of support for a "right to repair" and, perhaps, more of a concession to the assumption that the average buyer would need to repair the device sooner or later? Definitely an excellent practice for any electronic device, nonetheless!

The presence of other voltages would not surprise me. The Soviets also had an isolated 42 volt system in safety critical areas such as schools. Many countries started at 110 and moved up to 230 over the decades. These transitions usually take decades to complete. I understand there were even parts of the UK that historically used different voltages. The reason the plugs on the continent are not polarized is due to Europe's transitional electrical systems where 220 volt outlets were actually two different phases of 127 volts. Some parts of the world still use this type of 127/220 volt system.

[@tehlaser]

Speaking of unusual ionizers, I’d be interested in seeing an anti-static ionizing “gun” taken to bits if you happen to run across one. They’re sold to audiophiles to help remove dust from vinyl records, but I’ve heard they’ve found use in laboratories too, though for what purpose I’ve no idea. They’re entirely manual, not having a power source beyond the mechanical action of squeezing the handle, and they come with a cap thing that goes on the end that’s supposed to flash orange (a neon bulb, perhaps?) to show that it’s working.

[@mfbfreak]

I got one of those. There's a piezo crystal inside, nothing else. In the dark you can see a faint blue corona dot on the pin. Not quite sure if it actually works on records, but you can charge and discharge (and over-discharge so reverse charge) an electrometer with it with ease.

[@curtisn6804]

They are used in labs, because materials/chemical compounds come as very fine (and expensive) powders that can hold static charges easily. And to get the best accuracy and precision in their calculations (while not using a lot of chemicals) labs tend to very small and precise measurements to which even static electricity can throw off. Its important because some chemicals can kill you even when its 1 molecule in a billion water molecules, so you don't want errors in your measurements.

A lot of people get tripped up by the thought that if the first stage doubles the voltage then the next stage must also double the voltage and so on. This isn't the case; if it were, this would be called a voltage exponentiator. No such beastie exists! It's called a multiplier because you're (theoretically) *multiplying* the voltage by the number of stages. Also, as Clive mentioned in his live build of a multiplier on a 3D printed form, there are always losses, so while there is no theoretical limit to how high you can multiply the voltage this way, you rapidly reach a point of diminishing returns.

If you need to translate something from Russian again, you can contact me, I will be happy to help.

This is due both to the government's attempts to popularize science, and to the peculiarities of the Soviet economy - it was often much easier for you to fix the device yourself than to buy a new one. Therefore, many Soviet devices have high maintainability. This device was produced in 1990, it is already the end of the Soviet era, accompanied by an economic crisis. This partly explains the use of obsolete parts - they just used what was available. Also, in the planned Soviet economy, there was no competition in the usual sense, so the factories had no motivation to constantly invent something new. Many models of mass-available electronics were obsolete. Of course, advanced technologies also existed, but were often inaccessible to the average citizen.
