Ah, i can see you have upgraded ur recording equipment, great success, have a good day sir. Just found ur channel, ill keep a watch from now on, so here's something for the algorithm
After watching Big Clive for ages I actually recognised the building blocks on the board and thought that’s a Cockcroft Walton Generator there, that’ll take the AC and make high voltage and when the schematic came out I felt a warm glow inside. I am actually starting to understand what the doodles mean! There’s a difference between between reading a schematic and actually understanding the ‘why have they done it like that?’ Long may you continue to reverse engineer stuff 🙏
When is an ionizer not an ionizer......when its an Ozone generator ! nice tear down, and another satisfied customer, the Green Band denotes 0.5% Tolerance, not, degradation of the paint from ozone , this backs up build quality...cheers.
It is highly unlikely that they used more expensive 0.5% resistors in a circuit like this where close tolerance is not necessary for correct circuit function. 5% tolerance resistors would be perfectly fine for operation of this circuit. Also, if you look closely at the 4.7ohm snubber resistor on the PCB the multiplier band ,which should be gold, is distinctly greenish further indicating that the gold paint has degraded.
@@stephenbell9257 Maybe, but thats still a lot of Ozone if it can attack the paint, I have seen resistors in some pretty aggressive environment's and not seen just one band effected, I have seen all though, I will review the footage...cheers.

Just to mention. I believe the input diode is in part to prevent the smoothing capacitor to smooth the whole 12V system. With the diode it does not need to smooth voltage drops when for instance the wipers are turned on or the brake lights come on. Keep up the good work.
@@snakezdewiggle6084 The cars voltage is generally referred to as being 12V. This 12V system powers all the electric equipment on board like lights, wipers, radio etc. During running of the car the power is delivered by the generator but over the same 12V system. And yes it is than a couple volts higher. So if the diode is not there the capacitor is 'trying to smooth' the whole system not just the ionizer. And if the the capacitance is not big this is not going to work when switching for instance the brake lights (non-LED) or while turning on the wipers. At the other hand i don't think the capacitor is needed as the ionizer will still work at the shortly lower voltage. And no capacitor than there is no need for the diode unless you want to prevent wrong wiring.
That's normal. Ozone is a strong oxidizer. Probably the soldiers will get quickly covered by SnO, the leads will get some iron oxide, the plastic on the copper winding will crack. Ozone is a problem for rubbers.
I have this model in my car, I no longer bother with air fresheners, it makes your car smell kind of like a hospital/sterile smell. Was impressed for the size so got my dad one for his car too. The only negative is the lead is soldered on, I would have preferred a removable power cord as you have to buy a 12v socket extender if you place it far from the socket.
I had one in my custom van here in Australia 1983... It was very noisy with a constant "hiss" .

Always got the show on the road...
Would the cap not need to be in parallel for oscillation, I’m not sure how the 180deg phase shift would occur with that gain structure, I think it’s more likely to ensure the startup conditions are met by providing a kick from primary to the feedback that doesn’t depend on the feedback winding, it probably is almost out of circuit at the actual oscillation frequency... it’s definitely odd though, I’d have to simulate it... I’d bet it’s fairly clever whatever it’s doing because it doesn’t seem like one penny is wasted building it...
@@robertw1871 That cap isn't really about feedback at all. It's purely resonance. The primary and feedback are electrically one coil as far as the cap is concerned, because they are in series. The phase shift for oscillation is accomplished by the feedback winding and primary being out of phase by way of the center tap and the components hanging off the base of the transistor... Start up bias is provided thru the 1k and 39k. That cap is mostly to stabilize operation; without it, the circuit will usually run, but will tend to be chaotic and lose some power to the instabilities, and operation is much more influenced by load. The most basic version of this circuit that still works is a single transistor and resistor with a center tapped primary. The resistor goes from the feedback side of the winding to the base, and usually has to be on the low side (a couple-few k) to get enough bias to start it... But it generates a lot of extra heat in the transistor and even transformer, and changes frequency at the drop of a hat because there's nothing really defining it. It ends up running with thick harmonics and whatever frequency "makes sense" at the time as it relates to load, inductance of the transformer, and parasitic capacitance of the windings.
My memory may be (probably) dull by now but am thinking back to the "Cockroft-Walton Multiplier" method for step up. Those diodes look a bit familiar in their config. Interesting Nice description Clive. :)
I thought all these operated in pulse mode! I see that I was wrong. Did you get a chance to measure what frequency the primary (at the collector of NPN) was running at?
Probably a reasonable thing to use instead of a can to refresh your vehicle's aircon vents. Plug it in and run the engine, air system on recirculation with the windows up... give it 5 to 15 mins and then unplug it. Part of your car care routine, rather than for using it while you're driving.

Hi random person you don't need high voltage to anodize titanium. Go to the "thought emporium" channel and he has a video on the process. I'll give a brief summary: Supplies needed *Salt *Water *Large clear glass or plastic bowl or tote *Carbon rod (or other suitable electrode) *Variable dc power supply Make a salt water bath hook the negative to the carbon rod submerse it in the water. Attach the positive lead to your titanium and then submerge it in the water. The voltage setting of the power supply determines the color of the anodization. Allowing you to select the color but it also means selecting the thickness of the oxide as these are related. Apologies if I got something wrong it's been a few years since I've done this.
With a circuit like that I might have put the LED in antiparallel across the transistor base-emitter junction. It would clamp negative spikes which could otherwise appear at the base and more importantly it would light up only when the circuit is actually running.
My first thoughts after the video was. Switch it over to solar and mount it to the dash. The lower power input of the solar can be put into a super capacitor to feed the ozone generator on and off. To keep the car fresh but not over whelming. What do you think?
Keep in mind the ozone is going to go after the rubber goods. Think of the foam behind the headliner. Too much ozone will likely start the interior disintegrating before it's time...

Hi Clive, there's a new mini dishwasher called bob. Its got a uv cycle for sanitisation. The uvc tube is behind what looks like a plastic window inside the dishwasher, can you do an investigation to see if the uvc would actually get through the plastic?
Way long ago, when dinosaurs still ruled the earth, and I was about 11, I built an "electronic combination lock" from a kit. This thing drove a small relay. I operated it a few times, and it stopped working. The driver transistor for the relay got fried by back-EMF from the relay coil. I cannot remember the name of the company that made this little gem, but I wrote them after I fixed it, and suggested that they include a diode across the relay to keep the transistor from letting out the magic smoke. That was, oh, good lord, 50 years ago. Cripes!
Clive, isn't that a one and a half stage multiplier instead of the 3 stage you said? Am I missing something? I thought that one stage consisted of two caps and two diodes. The missing cap and diode also have places on the pcb as well, they are just not fitted.
I think the 10nF capacitor its there to form the resonant circuit and determine the output frequency. I wonder how much RFI the circuit emits and at what frequency - has it got type approval ?
I would say this is a Hartley oscillator of sorts with the inductors going to Vcc instead of GND to save on bias resistors. The base cap and collector resistor probably help with starting. The other stuff on the base is to get the thing biased into conduction with 1uF being a short at ac. Hate oscillator circuits!!! Lol
I suppose Patreon supporters have early access to comments via URL link while the video is unlisted still. Then the video's posted timestamp is for when it is actually listed publicly
If the resistors are J/5%/gold tolerance band, I suspect there's copper in the paint. Copper + ozone = verdigris. I had never thought about this until now; it's good to know if you need to repair electronics that have been in corrosive environments. Could the 10 nanofart capacitor between the primary and feedback windings help to set the frequency of the flyback oscillator?
I wish there were affiliate links to buy the things Big Clive reviews. I want a car ozone generator and having one that Big Clive doesn't think is shit would be great!
Speaking of stabbing meat with a spike we need more Big Clive's electric cooking, and distillation. What if you put a steak instead of ground meat product. Try to carbonate/distill absinthe ♥️
Probably they used brass powder with glue for gold band and it oxidized to green, I have found quite few from salvaged electronics where that band has turned green._
If that 10n was a bit bigger say 100n (between primary and feedback) I would have said it was to help with self resonance and take some stress off the transistor.
What is your take on the "official" pentagon declaration about the unidentified objects spotted and recorded by some jet pilots? Fran made two videos about them

Exposure to ozone Can cause eye, nose, throat and lung irritation, cough and shortness of breath. May exacerbate chronic respiratory diseases such as asthma. Is likely to increase hospital admissions and emergency room visits for respiratory disease. Can also adversely affect indoor plants, and damage materials such as rubber, electrical wire coatings, and fabrics.
Clive didn't set out to make this video. I didn't set out to watch it. I must learn about this non-potted power supply in a sardine can. (Or was it kippers in the tin?)
@@bigclivedotcom I was reading up a lot on this last year when I was building an open-source ioniser unit based on stage multipliers. A lot of your teardown videos on Ionisers definitely helped me. Thanks a ton for that. I was talking with a few manufacturers in China regarding their ready-made $5-$10 potted resin modules(Step-up transformer-based), what they seem to agree with is that if the overall voltage at the needle tip is around 3-4KV (range measured with an ion counter) then ozone generation is practically zero. They say that's what is used to pass the UL2998 ozone standard(emission less than 5ppb). Higher voltages definitely can create ozone and you may not pass the test. For Ozone generation, a higher voltage is definitely needed. I don't have the equipment lying around to test this claim though. Based on what I read regarding the energy needed to create ozone, I think it's true. Keep up the awesome work with your videos. I definitely learn a lot.
There are a couple of questions about using such a unit in a car. What are the chances that the ozone generated will attack the plastic components in the car? While running an ozone generator, I have noticed tarnish developing metal surfaces. Having an ion cloud floating about in a car might not be such a good idea considering the modern electronics used. I wonder what it might do to such things as the touch screen found on GPS and entertainment systems. I think it would be very unwise to site in the car with this thing running. I suspect it will bind road dust and smog to the windows.
The odds? Pretty much guaranteed. Don't run it a lot, and if you've decontaminated your car, drive around with the windows open for a while. The tarnish happens because of the ozone breaking down. The O2 is freed on impact, and the extra O binds to something to become an oxide. I wouldn't run _any_ ozone generator openly where I'm breathing. I put one in a cabinet to help break down odors, but it was the same triangular one Clive uses in his refrigerator. I also keep the door closed to the cabinet.
Talking about tolerance bands on resistors... I have recently acquired a couple of metal film resistor kits with many different values. However, unlike with most carbon film resistors where the tolerance band is often gold, this isn't the case here. Most are brown but there are other colours too I think. This may be because the metal film resistors are blue and not tan, but I find them hard to read. The problem is that it's hard for me to tell in which direction to read them. Any tips to tell in which direction to read them?
Thanks for these videos. There is a product called Fast Start for rv air conditioning systems. It is pretty expensive and I am wondering what is inside.
@@unique3phase just hazarding a guess here, and I'm neither an engineer nor an HVAC technician. But I know my home window AC units (110V) pull a surge current at startup much higher than their draw while running. I imagine that surge is what's needed to get the compressor up to operating speed. So I'm guessing the easy start system you described is a capacitor bank that can help supply the surge current to start the vehicle's AC on a 15A hookup without undue voltage drop affecting anything else powered through the vehicle's distribution panel. Again, this is just a guess, consult an engineer :>
Hi ri run that one on my lived in motorhome amd i have no problem with it and after a week or so of running it 24 hours per day the stale smell started fading
how many stages could be put on it clive use a buck\boost converter and a power tool battery to power it. OOOO electroBOOM would love this one.........
In theory with a Villard cascade like this you can use as many stages as you like. The voltage across each individual diode and capacitor won't go higher than the input voltage. In practice the limiting factor would be that the voltage increases with the number of stages, but current decreases. At some point the corona discharge could draw more current than the thing could supply and you'd get better results with a shorter cascade. Keep in mind that what Electroboom put in that wand of his wasn't one of these, but it's a similar idea.
@@MostlyInteresting I like to wind my own transformers, inductors, coils, etc. There would be less than 300 turns on that one. I like to use black-lead pencils and Teflon tape for formers/bobbins.Good luck ;)
Thank you for all your replies. I would consider making my own but I am very busy at the moment trying to complete my workshop. I have been putting a workshop together for some time now as a place I can repair and restore pro audio equipment, but health issues have caused me many delays. I already have quite s pile of gear to sort through more related to my project but at the moment my bench is covered with things like cans of paint & brushes, boxes of wood screws, aluminium doorsteps and other construction materials. There are boxes and shelving units all over the shop. I have a car that has been off the road for 3 years that I now want to prepare for sale and I thought this ozone generator might be a way to freshen it up a bit. The car will be cleaned inside and out very carefully but filling the car with ozone would reach the places a cleaning implement would not.

@@bigclivedotcom I'm a bit of an alternative energy fan. I even set up off grid heating and cooling for a small church. You might be surprised by how many different ways to produce electricity. With your knowledge, I'm sure you power your cabin like a palace.
I dare you relabel it "electric harmonica" and re-list it.
"for in-car use."
"Only dropped once."
"Once upon a time in the west" would have had a different outcome.
Green *IS* a tolerated tolerance band color. It indicates a 0.5% tolerance
Hey Clive, I have some old smart home equipment that our local ISP decided to not support after only a couple of years and replaced with Google smart home stuff. Would you like these to tear down? I don't want to see the go to waste!
Great video Clive!
Hi Clive, there's a new mini dishwasher called bob. Its got a uv cycle for sanitisation. The uvc tube is behind what looks like a plastic window inside the dishwasher, can you do an investigation to see if the uvc would actually get through the plastic?
I ran an ozone generator in my bathroom and it corroded the chrome off of my faucet.
Nicely built , but I really hate the smell of ozone
Fantastic! Press onward Clive!
Would be fun seeing what the thing would do to the vehicle electrics if the metal cut through the wire insulation... :P
The cigarette lighter fuse of the car will blow.
@@s.hoffman7205 no, the current sustained by the secondary side is tiny, no way the fuse would blow.
It would arc and smell, but it's very low power.
Way long ago, when dinosaurs still ruled the earth, and I was about 11, I built an "electronic combination lock" from a kit. This thing drove a small relay. I operated it a few times, and it stopped working. The driver transistor for the relay got fried by back-EMF from the relay coil. I cannot remember the name of the company that made this little gem, but I wrote them after I fixed it, and suggested that they include a diode across the relay to keep the transistor from letting out the magic smoke. That was, oh, good lord, 50 years ago. Cripes!
It has a missing capacitor... Please add capacitor and check output before/after?
This PM60 Car Air Purifier Air Ionizer may be using a standard CCFL transformer.
It's a similar transformer to those used in CCFL drivers and some ignitors.
It should be safe enough, I can't smell it from here. 👍 🤣
Clive, isn't that a one and a half stage multiplier instead of the 3 stage you said? Am I missing something? I thought that one stage consisted of two caps and two diodes. The missing cap and diode also have places on the pcb as well, they are just not fitted.
Technically, yes.
I think the 10nF capacitor its there to form the resonant circuit and determine the output frequency. I wonder how much RFI the circuit emits and at what frequency - has it got type approval ?
I enjoy your channel
I would say this is a Hartley oscillator of sorts with the inductors going to Vcc instead of GND to save on bias resistors. The base cap and collector resistor probably help with starting. The other stuff on the base is to get the thing biased into conduction with 1uF being a short at ac. Hate oscillator circuits!!! Lol
They are silver bands on the resistors the ozone discolored them
Seems like a trivial task to Dremel off two or three of the points if it produces more ozone than you like.
I like my ozone soft and bumpy.
The lower load might result in more activity from the others.
@@bigclivedotcom Ah. Well, perhaps an appropriately sized bleeder resistor instead? Steal away a bit of activity?
how intriguing
The green bands mean that the resistors are 0.5% tolerance.
why does the video say it was posted 38 seconds ago, but the comments say 1 week ago?
Thats what I was wondering too?
I suppose Patreon supporters have early access to comments via URL link while the video is unlisted still. Then the video's posted timestamp is for when it is actually listed publicly
@@PhantasmXYZ correct the Patrions get to see it first.
Partly Patreon, and partly because if I release too many videos on the same subject close together, people get grumpy.
Bien
I’d love to see you probe it with the mini scope to see the frequency it oscillates at and how to vary the frequency by substituting components
There'll be an ideal resonant frequency for the transformer.
Found the same device branded as Neotec XJ-600. In the product description, it says it can collect dust. Did you find that it does?
The dust collection is incidental to the operation. More of a nuisance on these units.
If the resistors are J/5%/gold tolerance band, I suspect there's copper in the paint. Copper + ozone = verdigris. I had never thought about this until now; it's good to know if you need to repair electronics that have been in corrosive environments.
Could the 10 nanofart capacitor between the primary and feedback windings help to set the frequency of the flyback oscillator?
I wish there were affiliate links to buy the things Big Clive reviews. I want a car ozone generator and having one that Big Clive doesn't think is shit would be great!
Speaking of stabbing meat with a spike we need more Big Clive's electric cooking, and distillation. What if you put a steak instead of ground meat product. Try to carbonate/distill absinthe ♥️
Probably they used brass powder with glue for gold band and it oxidized to green, I have found quite few from salvaged electronics where that band has turned green._
Nice reusable transformer for projects. I guess you could probably run a neon tube from that transformer with out the multiplier.
looks very old school, but with that it might be reliable.
It does look a good reliable design. I think it has a long history.
If that 10n was a bit bigger say 100n (between primary and feedback) I would have said it was to help with self resonance and take some stress off the transistor.
What is your take on the "official" pentagon declaration about the unidentified objects spotted and recorded by some jet pilots? Fran made two videos about them
Probably a media distraction. But the universe is infinite, so there is other life.
@@bigclivedotcom maybe it's just a media distraction. Thunderfoot debunked it in two videos too. It was allegedly just birds and unfocused video.
So, if someone wanted to get their hands on some of the products you dissect in your videos (whether good or horrendously dangerous), where's the best way to find that info?
There are often links or keywords in the description. Most stuff comes from eBay.
@@bigclivedotcom Gotcha, I looked and just wanted to be sure I hadn't missed it! Thanks Clive!
Exposure to ozone
Can cause eye, nose, throat and lung irritation, cough and shortness of breath.
May exacerbate chronic respiratory diseases such as asthma.
Is likely to increase hospital admissions and emergency room visits for respiratory disease.
Can also adversely affect indoor plants, and damage materials such as rubber, electrical wire coatings, and fabrics.
At extreme levels yes. But it also occurs in nature and is an essential part of air as an active component.
What kind of spark gap does it have Clive? Is it able to jump all the way from your thumb to your forefinger? 😜
Very low current, so it would need to be connected to something like two metal balls to get a good spark length indication.
Where is a link to buy this unit?
Looks very well designed.
It goes under different names in different countries. All from one Chinese manufacturer.
Clive didn't set out to make this video.
I didn't set out to watch it.
I must learn about this non-potted power supply in a sardine can. (Or was it kippers in the tin?)
I just want to get a heart Icon from Clive
Here you go.
But I digress!! Haha 😹 you are Soo hilarious this was a great breakdown
@bigclivedotcom Why is this an ozone generator than an ioniser? Is it to do with the output voltages? Construction is very similar to an ioniser.
An ozone generator creates more ozone, but each has its own merits.
@@bigclivedotcom I was reading up a lot on this last year when I was building an open-source ioniser unit based on stage multipliers. A lot of your teardown videos on Ionisers definitely helped me. Thanks a ton for that. I was talking with a few manufacturers in China regarding their ready-made $5-$10 potted resin modules(Step-up transformer-based), what they seem to agree with is that if the overall voltage at the needle tip is around 3-4KV (range measured with an ion counter) then ozone generation is practically zero. They say that's what is used to pass the UL2998 ozone standard(emission less than 5ppb). Higher voltages definitely can create ozone and you may not pass the test. For Ozone generation, a higher voltage is definitely needed. I don't have the equipment lying around to test this claim though. Based on what I read regarding the energy needed to create ozone, I think it's true.
Keep up the awesome work with your videos. I definitely learn a lot.
There are a couple of questions about using such a unit in a car.
What are the chances that the ozone generated will attack the plastic components in the car?
While running an ozone generator, I have noticed tarnish developing metal surfaces.
Having an ion cloud floating about in a car might not be such a good idea considering the modern electronics used. I wonder what it might do to such things as the touch screen found on GPS and entertainment systems. I think it would be very unwise to site in the car with this thing running. I suspect it will bind road dust and smog to the windows.
Any touch device should be able to handle static discharge. Very high levels of ozone can affect some materials, especially natural rubber.
The odds? Pretty much guaranteed. Don't run it a lot, and if you've decontaminated your car, drive around with the windows open for a while. The tarnish happens because of the ozone breaking down. The O2 is freed on impact, and the extra O binds to something to become an oxide. I wouldn't run _any_ ozone generator openly where I'm breathing. I put one in a cabinet to help break down odors, but it was the same triangular one Clive uses in his refrigerator. I also keep the door closed to the cabinet.
Talking about tolerance bands on resistors... I have recently acquired a couple of metal film resistor kits with many different values. However, unlike with most carbon film resistors where the tolerance band is often gold, this isn't the case here. Most are brown but there are other colours too I think. This may be because the metal film resistors are blue and not tan, but I find them hard to read. The problem is that it's hard for me to tell in which direction to read them. Any tips to tell in which direction to read them?
I find it hard to read the blue resistors. If you test some and compare the bands it will give a clue, but measuring may be best.
Glad I'm not the only one.
Thanks for these videos. There is a product called Fast Start for rv air conditioning systems. It is pretty expensive and I am wondering what is inside.
Micro-air easy start. $300 for a small box that helps air conditioners on rvs start on 15 amp circuit.
@@unique3phase just hazarding a guess here, and I'm neither an engineer nor an HVAC technician. But I know my home window AC units (110V) pull a surge current at startup much higher than their draw while running. I imagine that surge is what's needed to get the compressor up to operating speed.
So I'm guessing the easy start system you described is a capacitor bank that can help supply the surge current to start the vehicle's AC on a 15A hookup without undue voltage drop affecting anything else powered through the vehicle's distribution panel.
Again, this is just a guess, consult an engineer :>
According to the website, the PM60 "Ion output: MAX 100,000/cm3", whatever that means.
It's lots. I think they make these figures up. There are a LOT of air (gas) molecules in one cubic centimeter.
I wonder how this would work with carbon fibers mounted to the spikes.
It would be interesting. That idea had gone through my mind.
Lovely find. It's always a bit disappointing to open up a product and find the goodies potted in resin/tar/epoxy.
Hi ri run that one on my lived in motorhome amd i have no problem with it and after a week or so of running it 24 hours per day the stale smell started fading
Very interesting. I'd love to see this on a circuit simulator.
how many stages could be put on it clive use a buck\boost converter and a power tool battery to power it. OOOO electroBOOM would love this one.........
In theory with a Villard cascade like this you can use as many stages as you like. The voltage across each individual diode and capacitor won't go higher than the input voltage. In practice the limiting factor would be that the voltage increases with the number of stages, but current decreases. At some point the corona discharge could draw more current than the thing could supply and you'd get better results with a shorter cascade. Keep in mind that what Electroboom put in that wand of his wasn't one of these, but it's a similar idea.
I need one.
Perfect review...just bought one :) lol
@Eddie Hitler174448437567
I had to get mine from a different source. They don't ship any of their products to the Isle of Man.
Where can I get this ozone generator? If it's eBay and I missed that (it's age) have you got a good search keyword. Thank you.
It's very easy and simple to make your own ! Just copy what Clive has here. Component values are not critical.
You want to look for "XJ-600 air purifier" or "XJ-600 car ionizer", they come with different brand names.
@@snakezdewiggle6084 the big hold up on that would be acquiring a suitable transformer.
@@MostlyInteresting I like to wind my own transformers, inductors, coils, etc. There would be less than 300 turns on that one. I like to use black-lead pencils and Teflon tape for formers/bobbins.Good luck ;)
Thank you for all your replies. I would consider making my own but I am very busy at the moment trying to complete my workshop. I have been putting a workshop together for some time now as a place I can repair and restore pro audio equipment, but health issues have caused me many delays. I already have quite s pile of gear to sort through more related to my project but at the moment my bench is covered with things like cans of paint & brushes, boxes of wood screws, aluminium doorsteps and other construction materials. There are boxes and shelving units all over the shop.
I have a car that has been off the road for 3 years that I now want to prepare for sale and I thought this ozone generator might be a way to freshen it up a bit. The car will be cleaned inside and out very carefully but filling the car with ozone would reach the places a cleaning implement would not.
I saw "it's not potted" and I'm thinking... Should it be?... No, no it should not 😂 it is also not a unicorn
