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.
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.

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!
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.
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 :)
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.

What happened to the livstream from last night...Did the booze result in more debauchery ...I left at 12:45am and notice it hasn't been uploaded lol...
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 :-)
I feel like they should have these in public restrooms. And maybe I should get one as Im allergic to everything plant based outside unfortunately, so my room could really use some fresh trace ozone.
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 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.
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 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?
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.
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.
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.
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?
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.
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?
Seller does not ship to Isle of Man (as of today)?😸😹 I had no idea there was such a great selection of these devices out there. Ozone generators and ionisers certainly seem to come in all manner flavours and colours. - Quite fascinating in their own way, aren't they? Mind you, a Thorn jellypot line output transformer and EHT multiplier, suitable juiced up, can whip up quite a lightning storm, if you want a shed load of ozone! 💥👃👷☠️💀😇🤔😹
"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 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?
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?
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?
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.
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.
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?
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!
@@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!
I found this on eBay where it is suggested to be used inside a car passenger compartment. Output voltage 3kV. Would this device be capable of igniting gasoline fumes assuming some careless fuelling of a car with a window open to allow the flammable vapour access to the car interior where this device might be operating ? Perhaps Clive could be persuaded to try an experiment with his remaining working device and a small amount of vaporised petrol.
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)
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.
Hi Clive. I watch (listen to really) many of your videos, while I'm servicing air rifles (random but true) I recently watched a repair of a tiny Chinese pulsing pump, and thought I'd gotten to the bottom of the problem with my haze machine. Turns out it was a tip of the iceberg and there is apparently a fault with the circuit board that controls the pump / heater / timer. I was wondering if it would be possible to post the job lot up to you, along with the return postage and happy to pay for any repair if you could figure out and possibly do a video of the repair of the thing. I use a nice ILDA laser, and the haze really makes it (as you can imagine, without it, the laser is pointless) You may be ridiculously busy, and not able to do it. As my dear departed of mam used to say "if you don't ask you don't get" Also used to say (in reply to "What's for tea?") Shit with sugar on. That's Yorkshire mum's for you. Best regards Mark.
@@bigclivedotcom firstly, I really appreciate you taking time to read my question. The pump is a brand new, the third one fitted ; here's the 'list of what's happening' Machine powers up & heats block correctly (drawing approx 800w) The pump will work ok-ish if the smoke button is pressed for a very short time. If the button is held, or timer function is used (as it would normally be) for any length of time, the machine stops emitting smoke and goes into 'sulk mode (won't do anything) If the machine is unplugged from the mains, short pause, plugged back in, it will do the same all over again. It may (or may not) go into 'heating up mode' on plugging back in, then work as described. If the machine is left on, with no button pressed for any length of time, it will go into sulk mode as described, not even offering to heat the block back up, but leds remain on, as if all is normal. The reason it is on its third pump is because the little second one suffered its inlet pipe snapping off, on removal from the machine (the quality of the pumps is not the best, I'm sure you know. It looks like for the plastic used in making or molding the little inlet was recycled and as such quite brittle and had very low elastic / plastic deformation tolerance (back in the real world when I was an engineer, one of our sites had a plastic recycling plant)
@@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).
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
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
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 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.

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)
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.
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.
be careful when combining acetone and heat, acetone is scary when it catches on fire, and the fumes are pretty nasty too
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 can never become weary of ionizers teardowns.
I’ve been a fan so long I remember when all he talked about was lights. Lol
Fanny flamebeaux doll..
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 :)
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.
You normally show an eBay page where you purchased - so we can get the same as Clive! But sadly not on this occasion.

The one with green and white wires is the correct unit. The others are probably just plain negative ion generators.
@@bigclivedotcom Thanks, just ordered 3. Hopefully they'll be fine run off 'wall-warts'.
What happened to the livstream from last night...Did the booze result in more debauchery ...I left at 12:45am and notice it hasn't been uploaded lol...
Booze + Livestream + Booze + More Booze = Editing
It's unlisted due to going a bit too wild.
@@bigclivedotcom just found the stream..wish i'd stayed up ! lol
Did you just coin the word "voltiplier"? Kudos!
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.
I feel like they should have these in public restrooms. And maybe I should get one as Im allergic to everything plant based outside unfortunately, so my room could really use some fresh trace ozone.
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).
Clive, I wonder if ozone can be used to check if in fact the craic is 90 in the ísle of man?
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.
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.
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.
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.
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 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.
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?
I would try turning the two sets of carbon fibre bristles round to face each other, obviously experimenting with gaps and ventillation access.
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.
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.
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?
Seller does not ship to Isle of Man (as of today)?😸😹
I had no idea there was such a great selection of these devices out there.
Ozone generators and ionisers certainly seem to come in all manner flavours and colours. - Quite fascinating in their own way, aren't they? Mind you, a Thorn jellypot line output transformer and EHT multiplier, suitable juiced up, can whip up quite a lightning storm, if you want a shed load of ozone! 💥👃👷☠️💀😇🤔😹
How much longer is "Big Clive's Wee Bit o' Ozone" gonna be in development? Is there a queue?
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 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?
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?
It's Sunday 25th of July. I enjoyed last night's live stream, and the fact I got to phone you, But I feel like shit. Tell Kevin it's his fault. :(
LOL
Awesome video clive. Love the ozone generator content
Can you help me with a simple PCB identification problem please Clive?
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...
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!
could you give a link to that 2 emitter ionizor? and how much is it.

Further Experiments ? Might end up with a Nikola Tesla style Lab with Clive throwing huge sparks.
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.
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.
Even if I were about to get ionizer fatigue, they’re so shocking that falling asleep is impossible
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.
Haven't had much luck de-potting things lately... I guess the LED driver manufacturers found out about DMSO...
I've resorted to heat to remove the resin and measuring components before they get damaged.
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.
In the past I used Methalene Chloride (Paint stripper) to depot epoxy. It was very effective.
They seem to have removed the useful products from the market.
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!
Also, all seriousness aside, I hear the hole in the ozone layer is beginning to close up. I assume that's all down to you!
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.
which make high voltage diode shown in video? with mark only of arrow?
They usually just have a pattern on them to indicate voltage. No manufacturers data.
I found this on eBay where it is suggested to be used inside a car passenger compartment. Output voltage 3kV. Would this device be capable of igniting gasoline fumes assuming some careless fuelling of a car with a window open to allow the flammable vapour access to the car interior where this device might be operating ? Perhaps Clive could be persuaded to try an experiment with his remaining working device and a small amount of vaporised petrol.
The discharge is too small to be an issue for that, especially when used inside.
@@bigclivedotcom Thank you for the reply Clive.
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
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.

Oh the irony if it came back in perfect English.
Hi Clive. I watch (listen to really) many of your videos, while I'm servicing air rifles (random but true) I recently watched a repair of a tiny Chinese pulsing pump, and thought I'd gotten to the bottom of the problem with my haze machine. Turns out it was a tip of the iceberg and there is apparently a fault with the circuit board that controls the pump / heater / timer. I was wondering if it would be possible to post the job lot up to you, along with the return postage and happy to pay for any repair if you could figure out and possibly do a video of the repair of the thing. I use a nice ILDA laser, and the haze really makes it (as you can imagine, without it, the laser is pointless)
You may be ridiculously busy, and not able to do it. As my dear departed of mam used to say "if you don't ask you don't get"
Also used to say (in reply to "What's for tea?") Shit with sugar on. That's Yorkshire mum's for you. Best regards Mark.
Have you tried powering the pump directly? They are very prone to jamming.
@@bigclivedotcom firstly, I really appreciate you taking time to read my question. The pump is a brand new, the third one fitted ; here's the 'list of what's happening'
Machine powers up & heats block correctly (drawing approx 800w)
The pump will work ok-ish if the smoke button is pressed for a very short time. If the button is held, or timer function is used (as it would normally be) for any length of time, the machine stops emitting smoke and goes into 'sulk mode (won't do anything)
If the machine is unplugged from the mains, short pause, plugged back in, it will do the same all over again. It may (or may not) go into 'heating up mode' on plugging back in, then work as described.
If the machine is left on, with no button pressed for any length of time, it will go into sulk mode as described, not even offering to heat the block back up, but leds remain on, as if all is normal.
The reason it is on its third pump is because the little second one suffered its inlet pipe snapping off, on removal from the machine (the quality of the pumps is not the best, I'm sure you know. It looks like for the plastic used in making or molding the little inlet was recycled and as such quite brittle and had very low elastic / plastic deformation tolerance (back in the real world when I was an engineer, one of our sites had a plastic recycling plant)
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).
Big Clive Ozone Ionizer ASMR.
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'm a simple man, I see *"POT"* in the title, I CLICK !
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.
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?
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.
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
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.
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.
@@bigclivedotcom
Thank you for taking the time Clive. Very kind of you.
