Having already taken the 220V version of this product apart and discovered its use of a very small voltage multiplier, I decided to get a 110V version to see how it differed.
It's VERY different, with an extremely minimalist transformer pulse circuit that could find other applications.

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

Why the hell do I think this is such a well thought -out design ??…I guess Im loopy from being up all nite soldering, to hit a dedline
👍👍
I used to have a battery-powered version.
I wonder if one of the emitters was thinner due to poor quality control. These low end modules vary wildly with ion emission. It’s a serious issue because if you have lopsided ion charge output, it can noticeably change results in air cleaning, or even make it worse. I don’t like low end bipolar ionizers for this reason
Hoping to see the 12v version some time in the future. I just purchased a couple of the 110v and 12v models to play around with. I'm curious to find out how much current the 12v unit uses while in operation, and also how wide of a voltage range can it effectively function. I'm hoping the run one on three series lithium ion cells.
Thanks for sharing this. I bought some of those modules for no reason (just for curiosity and cheap price), now I have a weekend project to try 😀
Would a uv light in the cheese drawer of a fridge. Stop the cheese from molding?
Not quite accurate on the carbon filaments. At these high temps metals oxidise and also become globular. Carbon is more resistant to oxidising and won’t go globular due to melting at the tips. 😉
I tore apart a tower fan that had stopped indexing L/R from center . It had a long , small diameter squirrel cage it use to move the air and the indexing of the housing was done with a bell crank and offset arm. Point of this reply is that it had a o-zone generator built into the system also as when I found the carbon filament discharger leads and circuits I wasn't able to come up with what this all was until much later. I still have the components stashed away in my electronics tote but to say it wasn't encapsulated like the one you struggled with and yes it was feed from standard 115 VAC,, It wasn't built like the one you showed but rather had the input section of the PCB have the multiplier for the higher feed AC if I remember correctly. Nice video , thank you Clive.
Clive, I believe that the diode across the scr also has the function of acting as a 'disconnect diode'' to insure that the scr 'turns off' right after the current pulse. This is quite important in scr switching circuits of all kinds.
Digging this! These ionizers and other high voltage stuff potted in epoxy always fascinate me. The epoxy makes me want to see what's inside!
the 12v and the 120v ones are for small fridarators for cars
Double diode works wonders, works wonders – you have be British and be of a certain age to get that reference.
