From the same range as another unit I looked at recently, this one has an open PCB power supply with a very retro, but good high voltage PSU.
Unlike many of the cheap eBay modules, this one hasn't skimped on components and pushed them hard. Instead it seems a logical and well thought-out design with the components kept within their ratings.
The filter across the transistor and complex feedback array to give fast transistor switching show that the person who designed this was knowledgeable in this area of design.
Current draw of this unit is around 100mA at 12V meaning it might be suited to use with a small solar panel in a remote location to keep cabins from going stale.
For those who haven't guessed, the unit is a vehicle ozone generator, which would actually be OK for freshening a stale vehicle interior, but might be a bit too strong for continuous use in a small vehicle cab.
The high negative voltage on the spikes causes a plasma discharge at the spike tips, and the charged air then gets attracted towards the positive plate, causing a surprisingly strong airflow with no moving parts. The plasma discharge causes oxygen molecules to break into separate oxygen atoms that can recombine temporarily as ozone and other molecules in the same process found in nature. These active components of air are a natural air sanitiser that has the ability to deactivate airborne contaminants like viruses, bacteria and spores. Although ozone is harmful in large quantities, it is safe at the levels found in nature.

This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.

Wow
Ze classic multi section high voltage transformer
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
Where is a link to buy this unit?
Looks very well designed.
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 ?
Can yo make a reverse engineering for humidifier circuit
So what is the open circuit voltage from this unit?
An Ebay search makes me think that this is the model "PM60." There seems to also be a model PM100. The company info on the PM60 has a UK address, so maybe this is better built, because it is not from China?
I am sorry to have to make this comment on a public forum but there are no avenues available to do otherwise , so , I have made numerous attempts to watch and listen to your videos HOWEVER, trying to understand your speech is a lesson in futility. Your enunciation is utterly appalling , it's as if you are trying to speak with a mouth full of food or in my country , a mouth full of samples. I'm not trying to be harsh but I am going to forgo watching your videos to keep from loosing my composer and damaging my computer. I really like your content i.e , the topics and subject matter but I also like understanding the narrative. Thank you for your time and hopefully I will see and understand you in the future .
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?
But I digress!! Haha 😹 you are Soo hilarious this was a great breakdown
Why would you want to generate ozone in a vehicle?
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 love how Clive keeps saying "modern lead free solders". And I agree it does feel that way. But the RoHS went into effect in 2006. That's 15 years ago. 😉
(Feel old now? I do)
