Intriguingly different "ioniser" module (de-potting and schematic)
Vložit

- While scouring the Internet for interesting high voltage modules, I came across this little unit that stood out from the others by having two different coloured leads going to a classic double carbon-fibre emitter. There was no real information regarding its function, so I bought one to analyse.
It was either going to be just two random wire colours commoned inside, possibly a high voltage one and one referenced to internal ground or possibly even opposing polarities.
When it arrived, the first test I did was to see if both emitters were directly connected. They aren't. I then powered it up and used the floating probe test in front of the emitters to give a rough indication of ion polarity and level. The white lead showed a negative potential and the green one a positive potential.
A full depotting and reverse engineering shows that the high voltage side has only a slight capacitive coupling to the low voltage side, and uses a two capacitor/diode voltage multiplier for a high negative voltage on the white lead, and the green lead is effectively high voltage ground.
The vicinity of the carbon fibre tufts to each other, and high potential difference between them results in a very faint purple corona discharge on the tips and a very low level output of ozone. It appears that the primary function of this device is purely trace ozone production.
I'd guess it's designed for use in generic fan/filter units for small rooms, or perhaps for vehicle use.
The power consumption of the circuit is surprisingly low. It runs on 12V (with polarity protection) at a tiny current of 17mA (0.2W). That would make something like this perfect for use with a small 50mA 12V solar panel for adding a slight hint of ozone to remote buildings/vehicles likely to get musty.
The lack of direct connection to the 12V supply and effective ionic "short circuit" at the emitter head suggests this unit won't have the issue of classic ionisers creating a high voltage difference between the primary and secondary of an isolated power supply.

Never get tired of listening to Clive talk about ozone
You had me (sleeping like baby) at "talk".
It's a gas!
Same
"cus it turns out that's what it does" The words of a professional!
thanks for sharing so much knowledge throughout the last several years
Ok, *fine*, I'll order five of these from China and join the trace ozone club. If I gain any superpowers as a result, it's all your fault, Clive.
Everyone's favorite hero: The Ozonator.
@@JoshStLouis314 More like Doctor Pulmonary Edemator
The public obsession with ozone, reminds me of the radium fad, where every new product, even toothpaste, had to contain a trace of radium, because of its "health giving vital properties".
@@ts757arse ozone, just like radium, has its uses, but breathing it is not one of them. It does make a great disinfectant. I am curious about the chemical residue it might leave behind. Ozone attacks carbon double bonds, breaking them apart by forming unstable ozonides. Some plastics are attacked by ozone, making them brittle.
Yeah I'd tracked one down before he'd got to the reverse eng. Still waiting for the last two ;-). This winter I shall bath in closed house purifcation bliss.
Thought I smelt Ozone, and then this dropped.
Entertaining as always.
Do people actually complain about these these subjects?
Because if so I would direct them elsewhere it's that simple.
You have to try and please everyone - which is actually impossible.
A lot of people complain about a lot of YT video, in a lot subjects. Quite why they don't just go and look at something else that does interest them is a mystery to me.
Would all those complaining about people complaining in the comments please find somewhere else to complain…
This message was brought to you by the blooming obvious foundation 🤪
@@whitesapphire5865 princess syndrome. Spoiled kids who think the world revolves around them. They non-ironically think clive made this video *for them*.
Make videos about what you are passionate about! We'll watch!
Yes, some will complain no matter what the video is about. They just aren't happy unless they are complaining!
Complaining is part of the fun.
So true!
I for one, love seeing snowflakes melt right in front of me!
Don't worry about covering one subject too much. We enjoy your enthusiasm.
Those not interested can watch the fearmongering BBC instead.
Based on my talking with Chinese manufacturers making these potted dual-rail ion generators, the output voltage at the brush end is what determines if a unit produces traceable levels of ozone. What they seem to claim is if the output voltage is capped to 3-4KV then it should pass the UL2998 ozone standard(emission less than 5ppb). This is the setting they claim to use for folks who need to pass the UL ozone standard.
It's probably the same reason traditional ionisers cap the multiplier at 11 stages.
That's assuming they actually are trustworthy and build to spec. Look at all the lasers that are sold on Amazon and EBay from China. They are all listed as 5mW lasers.
In reality most of them are at least 30-50mW lasers which are quite dangerous to your eyes. You can buy them for under $10.
For $50 to $100 you can buy a laser that outputs 1 to 2 Watt. Once again they are listed as 5mW lasers.
They can cause severe eye damage and even blindness from just a reflection or a quick moving beam across the face.
@@jTempVids they are listed at 5mw for legal reasons as you know a laser isnt 5mw when the pics in it show a bright beam
@@jTempVids good to know.
@@plainedgedsaw1694 Yeah, to buy one!
Clive, I have been watching your videos for years. You really are fantastic. I don't understand how you get the time to do all of this but it's much appreciated.
Even though I have been watching your videos, with the intention of learning electronics, I am still utterly clueless.
I am more of a kinesthetic learner for sure. Still love your production and the chilled vibe of the videos. So easy to watch.
Us Brits seem to have a different style to our American cousins. No jump cuts less scripted and generally more chilled. I find that funny. I have had go unsubscribe from some American CZcamsrs wwaaayyy to over the top.
Keep up the fabulous work.
You'll find it all just gradually falls into place like a jigsaw.
Born to learn looking forward to next experiments thanks for all your hard work. Cheers Stephen
Those separator things remind me of those red light therapy nostril LEDs, not sure that these would have the same effect though if stuck up one's snout... :P
i have those but is very uncomfortable to use as you get a runny nose. i bought red led 3 watt beads and apply them externally instead.
High voltage and LED projects never gets old.
If you think you are doing too many videos on those, you're not doing enough! :)
Really enjoying these. Perhaps someone will volunteer to complain about them, so we can all pounce on them, with our ferocious righteousness, which can be fun.
"ferocious righteousness". The best kind of righteousness! 👍
no fatigue, please more ionizers and ozone modules!
I wonder if you could make a metal screen dust filter, that uses high voltage to make dust stick to it, rather than relying on a fine mesh to screen air. The main advantage being less airflow restriction.
Electrostatic precipitator.
@@bigclivedotcom It seems i'v been beaten to the idea by a century.
@@bigclivedotcom Which was the very heart of the fume extraction system in the welding workshop at the college where I used to work. The precipitator was also water washed to clean the screens!
I'm a big fan of you depotting them. Maybe film some of it for a long video? A thing I don't understand in this video (1:00): How is ozone meant to be generated when there's continuity between the both sides of the filament pairs?
The one with the big bunch of emitters is purely an ionizer designed to put an electrostatic charge into the air, but will still have a small amount of corona discharge on its emitters, so will still produce trace levels of ozone.
@@bigclivedotcom we just got one of these. So if it only produces low levels it's probably fine to let it run all the time?
Well, this time all i felt was the whoosh of that brushing over the top of my head! I need to watch it again!! LOL
Awesome video clive. Love the ozone generator content
Very cool, I have AC and DC types. Never thought of probing them before, I figure you will get around to it and save me the time and mess.
Don't worry, I can't get enough of HV module stuff!
Thanks for the early sneaky link. The secret methods of ionization shall be revealed to me.
I'm here for the myriad, circuit design ideas. Oh, and Clive's masterclasses in schematic art, thats pure gold right there.
Clive, while de-potting, would you mind swapping that sharp knife for your spudger instead plz... one xmas eve I managed to pair flesh from bone, the full length of my left index finger. IT DOES NOT MAKE YOU LAUGH !!!
Chill the potted item to 2 or 3 degC, warm the acetone to 20 degC, cover, leave o'night.
We do like a good strip down.
I can never become weary of ionizers teardowns.
Just what I didn't know I needed to know!
I’ve been a fan so long I remember when all he talked about was lights. Lol
Fanny flamebeaux doll..
I have one of those modules with ten emitters, and it died on me after a few months.
Haven't tried to remove the potting compound though, to see if I can find out what failed.
I'm a simple man, I see *"POT"* in the title, I CLICK !
I've had that strange thing happen when trying to remove things with solvents. It goes so deep and stops. I've wondered if the solvent swells the material and bascily gets too tight for the solvent to get any deeper. Stuff to think about when you really need to be asleep.
I ordered a couple after seeing one of your ozone video's.
Sold as car air purifiers I thought it may be OK to use as a trace ozone generator with 12v 'wall wart' plus a timer.
Will probably check for reverse EMF as I've measured over 300V on motorcycle primary windings (although it needed a peak voltage adapter to get any reading above 14.5vDC)
Yeah, these are pretty common now in a buttload of air purifiers. First time I encountered one of these was in my Oreck air purifier that use that funky Truman cells for trapping fine particulate.
I admit I'd love to combine this with your filter fan 3d setup. Maybe add a timer for the 12v ionizer to trigger for a minute once and hour. (Heck maybe two knobs. One for fan speed adjustment and one for timing adjustment.)
Very cool! I will have to grab some and experiment. Safely of course.
Big Clive Ozone Ionizer ASMR.
you can turn an ionizer into an partial ozonator as well by bringing the emitter close to the ground plate or neutral from the mains and the amount can be regulated by how close you bring it to the ground/neutral....
That's in an upcoming video (already recorded) with custom designed PCBs.
OMG 8.5 min in! Clive's simplified version. He mixed up his current convention. Never thought I's see the day.
I never get sick of the ozone talk. I just bought one from Aldi's that had been reduced 50% so I got it for just $25. It has a built in motion sensor, timer functions, and even a credit card size remote. Which seems excessive but that's OK.
can you give me a link?
@@esecallum It was in the store. They don't do online sales, unfortunately. I wish they would because I would like to buy another 12vdc drill and also a USB car boost pack as their prices are truly phenomenal. I will suggest to them online sales.
I love the smell of ozone in the morning
How much longer is "Big Clive's Wee Bit o' Ozone" gonna be in development? Is there a queue?
Very interesting.
Have you had a look at any of those little 18650 type battery spot welders. They look similar to mosfet output of those car jump starter things. Might be worth at look or compare?
I was sent one by a viewer. It will be featured in the future.
very nice
I'm curious to see your recommendation for a fridge and a house/room ozone generator at this point.
Since you've done so much investigation on them it seems you would have some good recommendations.
The twinky or "Japanese" fridge units are very good. I'm still testing room units.
Lovin the Home Depot
I feel like someone should make a remix 'song' of your more frequent wordings.
The title: "Explosion Containment Pie-Dish"
One moment please...
Clive is even capable of doing that himself, point in case the cheap pink charger of death from China.
ha ha
Carbon fiber might be hard to get a reading off of from the sides because its conduction (thermal and electrical) characteristics are often pretty different depending on what axis you're measuring. Something to do with the structure of the molecule. The graphene forms a tube, and for reasons quite beyond me, it's considerably easier for electrons to move through the tube in some directions than others. Such a cool, bizarre material.
Did you just coin the word "voltiplier"? Kudos!
I ordered one of these a few days ago to make my very own ozone generator. You say at the end of the video about the possible suitability of powering it from a standard 12V DC supply due to there being a high voltage ground. What might the risks be of doing so if there wasn't?
If the transformer core is ferrite, the schematic shows it drawn as typically two parallel dashed lines.
I somehow got the idea from somewhere that the bristles of the emitter had some radioactive stuff to make the corona give off ozone. Or maybe that was inside of neon lamps? Thanks, Clive.
Neon lamps used trace levels of radiation to allow them to glow in dark areas. Otherwise they don't start easily.
Clive, Did you measure the forward voltage drop of the diodes? The HV diodes are usually several junctions in series. Based on the forward voltage drop you can tell how many junctions.
I didn't with these ones, but the datasheet has forward voltage ratings for each voltage range showing a very high number of junctions.
10kV diode usually have a 9 V forward drop.
Clive, I wonder if ozone can be used to check if in fact the craic is 90 in the ísle of man?
Should I place this near or away from my computer for it to pick up less dust?
I'd recommend keeping any ioniser devices well away from computers.
I'm using the "multi-lead" version in my home "DIY Precipitron" which appears to work pretty well! Any chance of a review of the Maxitech MT7933 AC-DC LED Driver chip? These are appearing in a number of "better quality" LED lights, and the chip is pretty amazing (Chinese datasheet, machine translation!) Ta if at all possible!
It looks like a standard power supply chip, unless the main primary capacitor is not electrolytic.
@@bigclivedotcom You are probably right, however this chip is TINY, and in my case it was stuck under other components, so I was wondering what controlled the LED PSU until I did a bit of digging around!. Impressive how a very capable (and efficient) PSU can be produced with a few diodes, a power MOSFET and this type of very tiny chip!
so, you are making one out of the trigger txransformer units you got? Where did you get.... Refrigerator Ozone Air Purifier Fresh Deodorizer Fridge for 10 quid?
with the depotting would putting the item in a jar of acetone then putting the jar in an ultrasonic cleaner work better?
"Steve's Small Engine" got me to try different solvents in ziplock bags when cleaning lawnmower/chainsaw carburetor parts in an ultrasonic cleaner. Fill the ultrasonic tank with water, drop in the ziplock bag, and keep the cleaner until the parts look clean.
No fuss, no mess! You could easily try lots of different solvents to melt the potting compound.
I love how the subtitles translate "micro farad" to "meg fart"
Well that was a great video. Can these operate continuously? or they need cool down periods?
It runs cold.
Cool. Gonna get me 2. Thanks.
I can see the plastic coaster with fluorescent filling you made earlier, there in the left.
Would be good for a fridge, powered by 12v smps or smoothed®ulated 12v linear ps?
You can get modules designed for fridges that use mains power, or alternatively use a rechargeable fridge ozone unit. Look for my recent high voltage twinkie video.
@@bigclivedotcom Thanks Clive - I’m trying to avoid wiring mains into the fridge compartment, plus don’t trust the voltage multiplier- based circuit that employs only 120v. and i don’t want rechargeable. so i’m looking for 12v HF transformer based “non-ionizing”unit with very low output, which i will wire to automatically run whenever the fridge evaporator fan runs.
Curious colour code for the output wires. Is green the positive or negative? My guess, green is the high voltage ground and white the negative, but that is biased by the old uk mains colour code. I doubt if the Chinese manufacture has such a historic bias.
Any idea of the output voltage?
Please make a "how to de-pot (Chinese) circuitry" video ?
I have some small soft start modules which are stupidly expensive and am dying to know what kind of rare elements they used justifying the cost.
you'd think we would be tired of these ionisers, but no, not at all
Would these SMD parts be suitable for an all-SMD classic mains ionizer with no coils?
You can get suitable surface mount components these days, but the multipliers do require good separation.
I would try turning the two sets of carbon fibre bristles round to face each other, obviously experimenting with gaps and ventillation access.
Ah( i was hoping to see how to de-pot part. I hope you will make another video some day showing the whole process
It's very slow.
@@bigclivedotcom Do you just physically remove it or do you use some kind of a heat gun or solvent to do this? Is there a way to reverse the process and make some components watertight? I liked your previous video on making outdoor solar lights using old phone battery so I was wondering if one could make it more resistant to the elements by covering it in some material (like washing machine electronics).
The octopus module looks like full length of carbon fibre heater wire but the different colour HV leads just look like flex. I assume the carbon emitters are just crimped onto the ends.
Great little module. Probably order a couple for my ozone hoard.
Might be good for repelling squirrels from the bird feeder.
Wow. I ordered both types two weeks ago and are on their way to me now. I’m gonna make an ioniser project here at home. Thanks for featuring these products. Makes me more confident that they work.
By the way, have you already tried plugging the 12V ones directly on the mains of 220V?
Why don't you plug yours into the AC outlet and report back if you're still around?
@@piconano sorry. English is not my first language. I think I misunderstood Clive when he mentioned something about plugging this directly into 220v.
[Currently Unlisted Video] See, I pay attention to the comments. lol
Actually considering an ionizer for my garage/man cave. Thought about building one myself, which would be fun, but probably would be "noisy" enough to mess with all the electronics around me.
This module is very quiet in both audio and electrical noise.
yay for paying attention to the comments ;)
@@bigclivedotcom How is the RF noise emissions from these devices? As a ham radio operator, I don't want to and to the radio noise floor at home.
@@halohms For this unit I'd expect it to be quite low. A fraction of a typical lamp power supply.
Clive
Have you tried out your modified HV circuit on the device you unpotted, to see if it is more efficient?
It's potted which makes it a destructive process.
Hey bigclive, my air purifier has a pair of these carbon tufts as an ioniser in the outlet after the air has gone through a filter. If I wanted to disable the ioniser permanenty without opening up the machine would it be effective to just pull out the carbon with some pliers? Are there any potential pitfalls of doing this?
If I out one inside my dehumidifier (based on compressed refrigerant) where would be best to put it, after the fan, before the fan, before the air intake, next to the condensing wall?
Probably on the output of the fan.
@@bigclivedotcom if only I hadn't just have glued my case back together...
could you give a link to that 2 emitter ionizor? and how much is it.
www.aliexpress.com/item/32914804007
These low end ionizers are often capable of hcho and acetone Voc intermediates. They consistently show such byproducts in various studies/reports. And how you place the emitters can change ion output. They have to spaced appropriately
Technically all ionizers create some kind of ozone. Certified models don’t let escape/or measurable. Sharp plasmaclusters don’t create measurable ozone in the room. But remember, ozone can be a plus. A small amount of Ozone can actually in fact reduce ozone. (Via Voc reduction that would later become ozone otherwise). Not saying I recommend ozone, but it isn’t pure evil.
Can you make a demonstration of a white smoke turning invisible by generated negative irons with this. you can trap white smoke inside a glass container with the iron emitter.
This version is more of a trace ozone generator. It would probably precipitate the smoke on the electrodes.
I want to create my own static eliminator for a record player. Could one of these low volt ion generators be used? I've seen a static eliminator by Arlo Audio (Arlo Audio LP Static Eliminator).
I had the first one for a few years, but both silicone wires are white, though testing, one side is positive and the other is negative, which you'd thing might just cancel out straight between them, but never found a real use for it
It does more or less cancel out, but creates ozone in the process due to the higher current flow between the two emitters.
@@bigclivedotcom I'm wondering if you could seperate them with some mica, or cut them apart?
Wait, that feedback configuration with the single transistor... It's a high voltage Joule Thief!
That. Although clive might be correct in that the charging of the 1µF cap creates stimulus to end the on-time of the transistor, whereas the classic joule thief only has a resistor in that place, and relies on transistor saturation or transformer saturation to end the charging phase.
I heard that car-garages often offering a service to remove odors in a car with an ozone generator... But the units are ridiculously expensive. What would be a solid DIY solution for occasionally using in your eyes?
...use in the car, not in your eyes 😉
@ I almost started making a funny comment, you beat me to it... 🤣
@@shanesgettinghandy ...well it's the internet... You have to assume that someone will do a funny comment on it or get offended by it 😉
This little 12V ceramic plate ones sold on eBay could be useful for that.
The ozone causes rubber to deteriorate. Inside of a small space like a car, the ozone could cause damage to the rubber seals and weatherstripping. It's probably a good idea to leave the window slightly open when the car isn't used.
I am wondering if I should get an ioniser, if you use one Clive what is your choice and do you have a purchase link please
Or did you do a video about using ioniser and if not could you please do one(a video I mean)
It depends on your space. I'm liking this particular unit, although it is primarily a trace ozone generator for cars.
@@bigclivedotcom Thanks
As an aside, what do you want those plastic spacer chummies for?
For the exact same thing this module used them for. Positive/negative emitter spacing.
The text on the diodes might be solvable in your depotting bath and that's why it is missing.
I mostly used heat. While looking for new diodes for experiments I found they use the chevron pattern to identify the voltage.
Even if I were about to get ionizer fatigue, they’re so shocking that falling asleep is impossible
would it be possible to use this module for an electrostatic air cleaner?
It can have that effect. You could connect collection plates to the green wire.
@@bigclivedotcom Thanks again!
i have the 10 strand one. i arranged it in a flower pattern in a XJ-100 defunct ozonator case. only cost about $5 but the price jumped to $9 after i bought it...mains powered.
Still available quite cheaply. Should be OK on 120V but the 220V version may burn its resistors out quite quickly.
Can you help me with a simple PCB identification problem please Clive?
dug up some old parts from the mystery box and found a 120/3kv transformer, a set of X-Ray diodes, 20KV 102 blue ceramic caps... jumped the output of the transformer up to 12KV via some doublers and made a grid for producing ozone... I used 2 heatsinks from some old computer processor main chips... it worked fantastically, was putting out loads of ozone, had the room saturated within 10 minutes. Im either gonna have to remove a stage of doublers or find another transformer it was just too efffective :)
Clive, at the risk of testing your patience, re: my earlier query connecting the ioniser to a 12v car cigarette lighter: how do I know which of the ioniser's leads is +ve and which -ve? From what you said that isn't obvious? Does it matter? And does the cig lighter need to be fused?
In this unit the white was negative and the green was effectively positive. I would always recommend using a fuse. In this instance, 1A or less.
Have you considered rebuilding it with the alternative output circuit you suggested in the video?
It's potted in resin which would make that very time consuming.
@@bigclivedotcom Oh, I realise that. I was thinking more of "proof of concept". Reassemble (if all the components survived) the one you depotted but with a different VH circuit. But then it may not work without the potting resin for insulation.
The alternative voltage multiplier circuit doesn't work too well without using a two-transistor oscillator on the input to the transformer to provide power on both sides of the cycle, you get an unbalanced charging of the two capacitors, and you can only discharge through the pair what the least charged capacitor is holding. Protecting the transistor from reverse current is the ability for current to come off the secondary as quickly as possible, any limits there (such as by the capacitor it's flowing into being full) causes the voltage to rise on the primary side when the transistor is in the off state. (yeah, I had the same thought!) It works better with the Royer/Baxandall oscillator, as that will charge both capacitors equally :-)
This is sometimes used to provide a lower voltage on the positive emitter.
How do you recommend measuring ozone?
It's quite hard to measure accurately with rocket science. But as Okurka says, if you can smell it, then halve it.
And if you can still smell it in a room then halve it again.
Can these be used as static generators for use with model makers static grass applicators?
It may work. Even a simple ioniser module may have the effect.
Thank you for replying. I have bought static generators ie negative ion generators. 12v to 20000v I have connected them to a 12v motorcycle battery but they tend not to last very long. Would this be because the amp/hr on these types of battery are too high for the component and would I be better off with an 12v 1amp supply? Thanks
Hey big clive i have a cheap light bar and was wondering if there is a way i can send you a video. It doesn't seem to wanna pump out the power and draws .365mA
The 360mA sounds like a driver for a string of 1W LEDs.
So the ic chip would be limiting the power it has a few 47 30 rtv and a 50n06 so it should be drawing a bit of power. I noticed i put the decimal point in the wrong spot it should of been after the 3
I used to use air ionizers like that one, but they gave me horrible sinus headaches. I do get sinus and tension headaches a lot, but using those made them twice as bad. They'd make me have nauseating headaches on a daily basis. The dust was also ten times as bad. It would stick to everything especially around the ionizer. It just wasn't worth it. I just use air filters now.
I know zilch about electronics. So, how do you use this? E.g. can I just wire it up to a 12v car cigar lighter type of plug and simply leave it free-standing to freshen up my campervan?
Advice welcome.
Yes. Just secure the emitter where it stays dry and clean and doesn't rest against anything.

Initially an acetone soak, but alternating between a heat gun and a knife got most of it off.

Sounds like my old chemistry teacher. I asked why, and he said just because. LOL
Man, something about that font and the fact that there is text going both ways really triggered my dyslexia. I could've sworn the XHJ... and NO:20... Was printed mirror image. I legitimately forgot which way around a 2 and a J go. And there's a J in my name!!
It's an interesting optical illusion. I think maybe my brain saw KR18601 and then decided to compensate for the other lines by flipping them end-to-end (as if they were mirrored) instead of rotating them 180. So when I tilted my phone to read the XHJ, my brain was like. "whoah whoah, that was mirrored, so ALL of those letters are still backwards, buddy." even though they weren't!
You're peering through the simulation. Hang on to something buddy.
I wonder if an ultrasonic cleaner would be helpful in getting the acetone to penetrate... hmmm... how dangerous could it be???
I heard the output voltage is very high, 7,000v or more? Is it possible to measure it? Will it kill if you touch the output electrodes?
No. It's extremely low current. Like static electricity.
