Chizhevsky ion generator PSU full build

- The original concept of air ionisers is attributed to a Russian scientist called Alexander Chizhevsky.
I thought I'd honour him with a build of an ioniser with a needle array styled on the Chizhevsky Chandeliers, which were large ornate metal frames with lots of ionising spikes on them, that were hung from the ceilings of large public buildings in Russia.
The needle array I ended up building for this unit is based on a disk of PCB material drilled with holes and fitted with a circle of needles. I'd hoped to bend the needles out at 45 degrees, but they turned out to be very brittle.
In reality, while the electrostatic precipitation of dust was a useful if somewhat messy effect, the ambient generation of trace levels of ozone and other short-lived active molecules prevalent in natural outdoor air was probably the real reason the ionisers gave a renewed freshness to the stale indoor air.

I don’t know what that thing is, but it’s the best one I’ve ever seen.
I believe it's an ear wax remover of sorts or perhaps space detector @40:30 😜
It's an electronic box.
@@DenkyManner By the use of a modified ionizer device we describe effective prevention of airborne transmitted influenza A (strain Panama 99) virus infection between animals and inactivation of virus (>97%). Active ionizer prevented 100% (4/4) of guinea pigs from infection. Moreover, the device effectively captured airborne transmitted calicivirus, rotavirus and influenza virus, with recovery rates up to 21% after 40 min in a 19 m3 room. The ionizer generates negative ions, rendering airborne particles/aerosol droplets negatively charged and electrostatically attracts them to a positively charged collector plate. Trapped viruses are then identified by reverse transcription quantitative real-time PCR. The device enables unique possibilities for rapid and simple removal of virus from air and offers possibilities to simultaneously identify and prevent airborne transmission of viruses.
There is an urgent need for simple, portable and sensitive devices to collect, eliminate and identify viruses from air, to rapidly detect and prevent outbreaks and spread of infectious diseases1. Each year, infectious diseases cause millions of deaths around the world and many of the most common infectious pathogens are spread by droplets or aerosols caused by cough, sneeze, vomiting etc.2,3,4,5. Knowledge of aerosol transmission mechanisms are limited for most pathogens, although spread by air is an important transmission route for many pathogens including viruses6.
@@DenkyManner It's a Blue Box of Doom! 😬
Better yet. If Clive wired it incorrectly it could be a new drinking game for the next meeting of minds video.
Those mad soldering skills though. There is a man that doesn't need a wobbly helping hand from Maplins.
That 3d printed diode former is very neat.

I have brought more lead into the environment in the few years i fished as a kid than in all my years of soldering
the lead was mainly a phase out because of mass manufacturing, home hobbyists/professionals or even repair shops aren't going to pump out the kind of volume a factory could. and yeah, lost more lead fishing and to BB's as a kid. there's more lead pumped into the environment just from outdoor hunters...so anyone worrying about the lead in solder needs to get some perspective. yeah it's dangerous but good odds depending on where you live your environment gives you more exposure than what you'd get soldering. anywhere there was a war with firearms there's lead everywhere, pipes, paint, leaded gasoline/petrol...
perspective definitely required. sorry for the rant, studied lead and the environment, there's still some high traffic parts of cities where you can see old buildings yellowed/discolored from lead oxides (+ some other nasty lead compounds) from the days of leaded gasoline.
@@Joe-Dead totally agree
You use a car battery for fishing? Cool!

Back in the late 1980's, I bought a couple ion generators through the mail that had real good output, used about 4 watts. They gave me a free gift with them that I used till a few years ago. It was a pcb about an inch acrost and 2.5-3 inches long at one end was a small light, (maybe a neon?) And on the other, a metal pad, on the board, for your thumb. The light would blink in the presence of neg. Ions and the stronger, the faster the blink. It was great for testing how well your negative ion generators were working. I use to have a work area hood to pull air through a filter and in front of the filter, a negative ion generator and a florescent light. When the light was off, it would blink brightly about once a minite or two.
that diode forming jig is one of the things people will find in 1000 years and never figure out what it was for.
When I was in the animal trade, customs in the UK used to steal chameleons when they were passing through heathrow. I solved this problem by having the shipper add cobras to the paperwork, and label all boxes venomous even on orders that did not contain venomous snakes.
Perhaps the sneaky chameleons were not stolen, but just doing their thing really well.
Ironic that you had to commit fraud to stop the authorities from stealing from you.
Snakez Rule !
Customs are scummy thieves. All they do is steal money and packages from people.
There's something so satisfying about watching someone re-flow and straightening up the components! =)
There's another utuber who constantly tap-tap-taps the iron whilst soldering and makes me yell at my monitor! Dammit, man, just apply heat and solder... and be done with it! Clive knows how to do it well ;-)
Clive, I thought I'd heard the Cockcroft name before. He's none other than a co-winner of the 1951 Nobel Prize with Walton, for splitting atomic nuclei. He studied under Rutherford.
My favorite will always be 2001 A Space Odyssey (1968). The sets of inside the space craft and station "look plausible" because of the level of detail.
I built an air ioniser from a design in Australian Electronics Monthly many years ago. Funny thing was that it never got used for it's intended purpose. I had an issue with one of the neighbourhood moggies peeing on my front door, so I taped a sheet of aluminium to the lower part of the door & attached the output of the ioniser to the foil. Never had a pee problem after that. 😋
An old acquaintance worked for the National Coal Board (in the UK) and found that the other (miner) employees would pee on the corner of his Portakabin office, when heading to / from their shifts.
Eventually, he wired up a Megger to provide suitably-high voltage in the area, and the pee'ing quickly ceased.
IIRC there was a complaint lodged, but my acquaintance successfully claimed that the zapping was due to "static electricity" :-)
Relaxation to the 10th degree.
Like the way you move the solder to the next joint while stil finishing up the previous. Looks like a very smooth action.
It's quite a contrast to the butchery which could describe my soldering technique.
It's just good technique, if you don't move it the solder wire sticks
Amen Clive amen.... your rant about non technical people making decisions about technical stuff is spot on. The amount of fear people have over things they don't understand is mind blowing. Other day I was melting Am 239 pellets into larger pellets and my friends were freaking out cuz the geiger counter was 18k cpm and the metal was like 2150°F They were so scared and were like what does 18k cpm mean and I simply said don't eat it!!!
Yay! a build project. I love watching Clive the master assembler at work. Seeing all of these little tips & tricks in real time managing the practicalities of inserting and holding components along with the odd glitch and finger warming moment(!) really helps build my own confidence at the bench!
22:30 - 23:00 Well founded concept for a rant in my opinion.
I always enjoy a good kit build. The stories and information from commentary is always quite enlightening.
We're not scared of your face. You have a very kind face 😊
Run a bead of hot-glue down the circuit board for about 5 capacitors, fit them, then run a bit more glue, fit more capacitors and repeat until done. Then you can turn the board over and solder them all in. The glue will add mechanical stability to the caps too.
I do so enjoy watching you build stuff, Clive...True artistry!
You are such a joy to listen to Clive, thank you 🙏
42 minutes of soldering 👨🏻🏭 pleasure with questions!!! Bravo 👏🏻 Big Clive!!!
Great build, love the circuit boards and the translucent case is perfect for this
Thank you kindly for the PCB file! This looks quite satisfying to build.
Like you Clive, I am a big fan of these generators. This video had my attention from start to finish. Very nice compact unit. A+
Special effects so convincing: the next step is to show reality, but 'damage' it ever so slightly that you think it is fake.
We have a local landmark called Red Hill. The soil is red from the cinnabar in it - which has mercury. People live on and around the Red Hill, no one is complaining.
Really impressed by your multitasking abilities on this one. I barely could follow both your unrelated manual work and discussions, I have no idea how you manage to DO it. Great show ^_^
I remember many years ago when Ionisers were first a thing and my Parents had one of those pyramid ones in the living room. Me being the curious bastard i am was intrigued by it and noticed that from the side of the unit there protruded what looked like very fine wires. Well needless to say one has to touch it just to see what happens, well all i can say is it fucking smarted somewhat and i believe my hair did stand on end.....an interesting experiment if i do say so myself, although it doesn't beat the experiment i performed when i was about seven years old. This was before the times when we had three pin sockets with the protective earths on them instead we had two pin sockets with absolutely no protection on the plug or the socket apart from the old Wylex rewirable fuses. Again me being the little shit that i was when younger (my Mother always used to say she would shit herself everytime she went out of the house in case when she came back i had taken the tv to bits just to see how it works lol) so i found this hairpin (you can see where this is going can't you).and i thought to myself what is the harm in putting this in the two pins. what i remember next isn't very much apart from me putting the pin in then everything went black. I next remember running into the kitchen doing my best Al Jolson impression at which my Mother nearly fainted and my Dad nearly had a coronary. The socket was duly removed immediately. Luckily for me i had picked up a hairpin that had plastic ends on it so luckily i wasn't electrocuted (but i needed new pants).
I am definitely on team OpenSCAD for my functional modeling. It's so nice being able to do things in terms of components which are repeatable, especially when doing more complicated interlocking case designs. Plus I find typing to be way more accessible than mousing to me.
Nice to see another build Clive 👍 thanks.
Watching you solder that board is very satisfying.
There has to be a follow-up with a schematic discussion of Cockcroft-Walton multipliers. I know how they work, but I could listen to them being talked about all day.
Lead-based solders makes repairing stuff so much more viable that I don't think banning it completely has a positive effect on the environment. However, the switch to lead-free solder in production only had a temporary negative effect on the reliability of products (and hence the environment), but will from now on forever reduce hazardous materials being released in the environment. Hence I think the current situation should be maintained where it is allowed to use lead-based solder on a small scale.
Woo full build!
It's almost as good as doing myself except without the solder and coffee smell, but that's easily enough remedied! With solder...and COFFEE!
You rock man, and you rock the Isle of Mann!
It's very interesting to hear what makes fresh air fresh.
I made one of these some years ago as a negative ion generator, then found that if the protection resistor is switched out of circuit it can power a very effective anti-predator fence around my fish pond, with no permanent injuries!
Don't remove the resistor. That could deliver a direct mains shock. But even with the original resistors it will impart a nose-zap to critters.
Very interesting to see something built from start to finish
Another wonderful project! Thanks!
Every body smiles at explosions! Irresistible!
I love how easy you can contort your fingers to solder
May be we should have more garages added to our houses, after all I recon there was more designing and creating in garages than in Labs or any where else, by just normal technical people?
Still is. Britain in particular is full of silent inventors, with many of the technical breakthroughs never being made public.
Yes, definitely Britain, followed by New Zealand, then Australia, historically.
I am team "Makerspaces", where you can give the community access to all sorts of amazing prototyping/manufacturing/testing equipment in a similar manner to what a gym does for expensive exercise equipment.
You can even do small versions of these in garages!
(Also "toolshares" where instead of each person having a crappy tool for when they need it, you get a few great ones for your local toolshare that can be loaned out like books at a library)
@@ericlotze7724 now that is what I am talking about, why is there no local community centres where young people can go and learn for free what ever they are interested in, we need them every where local centres for skills the older or people with skills that have time could help with lectures and examples that the young and older ones can actually do.
Nice soldering and a cool Ionizer.
Hi Clive , I've been intrigued by these devices for a long time , good build . I like Jimmy 60 's comments , my shed is full of experimental gadgets , hydrogen generater , vortex tube etc, etc thanks again - Jim
Clive you solder basic through hole tech very much like me, although I don't "finger juggle" so much (hey if you can pull it off, as you can, there is nothing wrong with that, but my hands are showing my age and a life time of pro wiring), I use pillar drill & ball vices or crocodile clip type helping hands more often than you do. One thing I do though, out of habit, is to splay the leads out once they are placed through the circuit board to hold the component in place until soldering. It is good to see on TH-cam though, someone actually applying best practice to soldering.
All the best.
I found a great rechargeable ionizer I use in my refrigerator. It works well to stop cross contamination of smells and flavors. It is also supposed to keep produce fresher longer but I'm not sure I believe that part.
If it's a fridge ozone generator then it does kill surface bacteria on food.
@@bigclivedotcom It is designed and sold to be used in the refrigerator. Thanks for the ♥

nada mejor que verte trabajar eres un gran maestro. saludos
Fantastic little project!!! 💖🤩🤗🤩💖
I remember my first line-powered project build from the mid-1970s -- it was a relaxation oscillator-based neon flasher that spelled out my name in independently-flashing NE2 lamps built into a nice wood and naugahide cabinet. When I plugged it up, I was "rewarded" with a fairly loud pop, a flash of bluish-white light, and a puff of somewhat acrid smoke...oops!!! 😲
If I remember correctly, I had inadvertently connected a diode directly across the AC power input.
Very cool. Thank you Clive

Your soldering technique is so cool. SO much quicker than mucking about with blue-tack or other techniques I've tried in the past, though a prerequisite for having asbestos fingers ;-)
I'd like to see more videos like this it's very nice and it looks like it can be repeated.
Thanks, Clive!
Openscad is great because it lets you use version control. I love being able to pop out, branch off, and try something out. Sure, I could save off versioned file names, but that gets unwieldly fast and is why we have version control systems like git. I have no problem being opinionated on this: Openscad + Git is the best possible world of 3d modeling for anything other than artistic modeling use.
I was thinking on making an Open Source Electrostatic Precipitator sometime, and this will definitely come in handy!
Thank you Clive!
So I have just watched this for 42 minutes and I still have no idea what it is but it looks cool.
What a nice clean design.
I made one of these many years ago using pins for the electrodes. To test it I had a neon with a ceramic capacitor across it which would start flashing when held near as I was holding/grounding one side and the other collected charge from the air.
Both philips/cross head and flat head screws can make quite a bit of corona with all the sharp angles, a glob of RTV or hot melt on the output terrminal screw head might be a good idea... great vid
All we need now is to turn it into a form of ion propulsion, even Scotty is impressed at such technology... :D
Loving your "chopstick" soldering technique Clive :)
If you're interested in WTF FPGAs actually are, EEVblog did a decent video about them. The tl;dr is that they're exactly what it says on the tin - an array of gates with a lattice of connections that are configured on the fly. Most modern oscilloscopes, including the entry-level ones, run embedded Linux on FPGAs to get nearly real-time performance.
A fancy 2GHz scope I hired had Windows either XP or 7 lol!
I like the attachment you have in the thumbnail. Looks very mysterious.
It's in the description.
Being an old fart who was alive and watching TV when Star Trek came on first run, I had to comment. In 1971 when i returned from my tour in Vietnam, I was stationed out at Fort Lewis Washington. We found an apartment in Tacoma where my wife, and our son lived. We still had an old Black and White TV, but our neighbors in the next apartment had color. It was there that I learned to my despair that Spock had white skin and not green as I had always imagined when watching it in Black and White.
Bought an ioniser a couple of days ago and have been running it 24/7 in my bedroom. Not sure if I've fallen for the quackery but the air even FEELS cleaner.
I remember the ionizers used in bars to neutralize the tobacco smoke. I remember a reseturaunt I cleaned wanted me to clean theirs. I told them to get bent. It was 20+ years old and never cleaned. I told them it probably not work again if I cleaned it. A month later, they removed it and trashed it.
Great video! I love doing these chips cant wait till I can design my own! After hearing you say carbon Fibre, I think it's time for a burglar alarm teardown 😉
My favorite quote: "Nothing beats bringing in air from the outside but it's not practical all the time for heat reasons". Outside air is normally so much cleaner then inside air.
Hi Big Clive. My favourite youtube person. I reckon you might want to reread the current research and scholarly articles on the toxic and pathological effects of ozone on lung and other tissue in concentrations that these little devices put out. Cheers mate.
These units put out much less ozone than occurs in nature. If you stood on your own in the middle of a remote forest you would be breathing in 100 trillion molecules of ozone with every breath. It's an essential component of air that gets depleted quickly indoors.
To compare natural levels of ozone to concentrated and dangerous levels is like saying "Any humidity in the air is dangerous because people can drown in water."
When I worked for care refrigeration I did the ozone machine on the penguin pool at Bristol zoo it still keeps the water spotless in the pool today that was with a Dunham Bush unit and I did a lot of work off shore in the North Sea oil rigs all over the world as well regards Kev.

The reason for nonlead solder is for plumbing applications, because no one wants lead in their water.
Unfortunately it was also applied to electronics.
@@bigclivedotcom I was in water treatment for about 12 years. I’m pretty sure you can still buy the leaded version here in Canada, you just shouldn’t use it in plumbing applications.
I was watching the fur attached to the end of the wire attract to the probe at 37:52. Nice build.
Very therapeutic video, as always Clive. Thank you. On the 3D printer side, from your comments it sounds like you are using PLA for printing. I also had some of the problems you have had and found that borosilicate glass was the answer for me. It also meant I could remove the glass and clean it easily. The glass is held down with paper clamps onto the heated bed and I use Pritt glue stick (not the cheaper alternatives from Poundland I'm afraid - I have tried) to apply a thin layer to where I am printing. Works a real treat and as soon as the bed cools the part just pops off. In winter I bump up the bed temp up from 40 to 50 degrees to make sure my cold house doesnt cause the part to detach prematurely (has happened...). To clean the glass, just ordinary soap and water is all that is needed. If you dont have some of this glass, let me know and I will order some for you.
A new layer of glass is a good idea. I wonder if it would work with picture frame glass.
A good result!
Cable tie cable clamp is an excellent idea

Good Tuesday morning to you sir
34:59 I'll always remember my first bang. I was building my first-ever boardless 110-V-powered LED light. I used too big a capacitor with no resistor to limit the inrush. One of the diodes left a very pretty-colored spot in my vision before it tripped my circuit breaker.
That's not what they meant by light emitting diode lmao.

Back in the early 80's ETI magazine published a project complete with PCB track pattern that you etched yourself, and it was the same as this, a mains input with the Cockcroft/Walton multiplier, I built it and it worked very well, I remember getting in bother from my old dear as the wallpaper behind the thing was blackened by the charged dirt particulate leaving a 'shadow' of filth, to me it was a wonderful example of Physics in action, however to her it was a disaster !..cheers.

@@bigclivedotcom Yeah, I might make yours.
We need to design a 360-degree lighting rig for Clive.
Saying that he can't do it is a challenge.
What about some LED tape attached to a flat metal ribbon-style spring with a width of maybe 2cm or 1/2in and heat-treated to have a resting state that is a cemicircle with a radius of some value between 0.5M and 3M.
The diameta/radius would be chosen to allow comfortable access to the workspace.
The whole arrangement would coil up into a ring for transport.
Holding several such strips would be either generic clamps or simple weighted bases , probably just being a block of wood with a bulldog clip or similar cheap common clamp; perhaps with a slotted affixment piece made from a standard L-bracket and some folded sheetmetal.
Power to the strips would be supplied by whatever connector is typically on-hand.
Ideally the strips would be diffused, whether by buying a diffused light strip to start with or having a translucent diffusion layer in front of the LED strip.
Supply would be by some broard-input-range regulator with a bunch of different type of sockets for input, so you can use any power source capable of more than five volts that is on hand.
Basicaly it'd be like a big hula-hoop over the workbench that shines light inwards.
That would cause a lot of glare in reflective objects.
Blimey. Electronics Today International. There's a blast from the past. It was that magazine that sparked (ho ho) my interest in electronics as a young teenager and as you can see by the fact that I'm here watching this video, it's an interest that never left me.
Another source for finding carbon wires, is to use inner wire from sparkplug cables. Carbon wires are there used as a resistor for surpressing EMI.
