Excellent video, as always. You'd think they'd either have a separate switch on it, for the mains, or, as you said, route it through the potentiometer switch. I have a couple of these, so in the sprit of this channel, I drilled a hole in the case, opposite to the potentiometer and fitted a nice little round white 3 amp switch to the live feed from the plug so I can turn the whole unit off without having to unplug it. The live feed wire is just long enough that you can cut it, strip the ends, and solder it to the switch terminals, and if you drill the hole so it's halfway in the front and the back of the case you can pop it out if you need to access the internals in the future...

Hi Clive, thanks for getting this in and checking it out so quickly after I mentioned it. The video you seen was the one I did with the smoke and it did seems a bit iffy when I watched it and yours is much better with real information. I did end up buying two of these and both were slightly different as one made loads of noise and the other very quiet so I think manufacturing might be a bit hit and miss. Those green LED's are so bright in a dark room I put tape over them but wasn't sure if there was a reason behind them but after your video, I'm guessing not. The smell is very difficult to describe but the smell after a thunderstorm as they claim is almost right but not exactly it. I personally didn't mind the smell at first but after a couple of days, I couldn't deal with it anymore so unplugged them both. It's a bit naughty the company claim it to be an ionizer though as that's what I wanted to try out. I will keep my eyes open for other things like this you might fancy taking to bits. Thanks for the video :)

Ozone is indeed a fantastic odor killer. Years ago, we had a spare squad car that resided in the old Fire Hall. It was a late 70's Chevy with a huge engine and could catch anything on the road but burned tremendous amounts of gas so we were discouraged from using it unless the regular car was down for maintenance. Well one night a new cop on the force decided to take the old beast out for a shift, and during the shift he had to kill a skunk which was thought to be rabid. Policy says you kill a rabid skunk, you deliver it to the local Vet for testing. Well the fellow had a nice shift and got to try out that huge engine in a high speed chase, during which he forgot that he had that damn dead skunk in the trunk of the car, tied up in a plastic garbage bag. So at the end of his shift, he put the old car back in the Fire Hall and neglected to notify the oncoming officer of the skunk. Several weeks later, the decomp of the skunk burst the plastic bag, and the scent of that dead decomposing skunk infiltrated from the fire hall into old City Hall which was still in full use, and the odor got so bad that the on duty officer went to instigate. When he opened the trunk the smell of his vomit mixed with that of the dead skunk. The car was removed from the fire hall and the skunk delivered to the vet who immediately disposed of it because no testing could be done after the length of time. We called a local cleaning service, they brought over a rather large ozone generator and placed it in the front seat of the car which had been parked back in the fire hall. After 24 hours you could go back in the fire hall, and in fact drive the squad car with no trace of the skunk. Now that's a cleaning service!

Afternoon Clive, came across these being sold in my local B&M Home Store under the Blaupunkt brand for a tenner, and bought it knowing full well what it was having watched this video in the past, the manual hints at its operation as an ozone generator but mentions negative ions and the basic operation of an ioniser, which this certainly is not, in the manual. Couple of hours running in the bedroom and it freshened it up some, and after unplugging it a distinct ozone smell on the output. Shining a torch inside the coloured plastic in front of the LEDs and through the fan grille on the back it looks to be pretty much unchanged circuit wise, I haven't had it apart though to investigate further but I cannot see it being different inside to this Puripod one you looked at.

Excellent brief description of ozone creation and purpose. It took two days in organic chemistry 201.

I just got a mini oscilloscope myself because I don't have a real one and I only need the basic operation of this little one. I found it works great. I can see I'll need a real one soon enough.

Reminds me a bit of the Reme air purifiers we used to install at an old job I worked at, our salesman claimed it was some super high-tech catalytic air purifier, but I could tell just from the design of it, combined with the odor it put off, that it was an ozone generator, but it is also coupled with a small UV bulb.

@SeanBZA

Those are repurposed LCD backlight transformers, but these are not diode split, just the segmented windings is done to reduce interwinding capacitance, as the sections have a lowish voltage between them, and a very low capacitance, so the losses in the transformer from circulating currents are a lot lower. Also allows the transformer to have each segment act as a LC tank to build up the voltage in each section for a higher output than the one expected from turns ratio, as they are all series LC oscillators added together, giving the very high voltage to start the CCFL tube when cold, but then as the tube starts the ionised gas inside puts a load across the transformer and this then kills the resonance on the steep edges, leaving the voltage being just turns related again mostly. Makes it easy to control the wide voltage swings of a CCFL tube for starting and the requirement for current drive when running with simpler primary side only sensing and almost no high voltage components aside from some ceramic capacitors and resistors.

The way that Wikipedia has updated my knowledge of ozone is that it is O2 that has been electrically split into free Oxygen atoms which promptly bounce into an O2 molecule, glomming onto it producing ozone (O3), which is unstable. They bounce into other stuff as they float around waiting to stabilize and occasionally bounce into contaminants or solid objects like metals and react with them, usually enthusiastically to try and get rid of the 3rd Oxygen atom.

Jacuzzis will either have a UV light or an ozone generator to keep it clean. It's widely used in hospitals. Restaurants can use ozone generators in walk in refrigerators. I have built a couple myself for odeur removal in ie cars as it will neutralize both cigarette and wet dog smell very effectively. Of course, it will accelerate oxidisation. Another great use is in water damaged basements to kill of mold etc. Very useful for loads of things. This generator probably produces less than 50 mg/hour, whereas a generator for odeur removals for cars should generate at least 5-6 gr/hour for DIY and 30 gr/hour for commercial use.

the none ground referenced (don't care if it gets f'ed) little scope. Very handy for these things.

14:25 Depending on the position of the coils relative to each other, it could be that the designers required 'mutual inductance' in the circuit. This inductor may take the place of a protection diode not seen here often found in these circuits to protect the MOSFET.

I would greatly appreciate a video about the variety of oscilloscope display devices you have access to from the cheapest functional units to the really spendy units. I stopped using them when I left the US Navy back in 1993 and I am sure that anything I used then would have capacitors that will have aged out of spec by now. All of the more recent models will be microprocessor based these days and the costs are going to be all over the map. Nice work on your vids BTW.

Yes, pin 5 is CV - Control Voltage. A capacitor (typically 10nF to 100nF) can be added to smooth the voltage on the internal voltage divider resistor network.

On CMOS versions of the chip, or where the NE555 is being used and stability is not considered important, the pin can be left unconnected.

Interesting to see the good old triple-nickel. I bet the ubiquitous 8-pin microcontroller doesn't run at a high enough frequency to drive the circuit, especially since you want to vary the duty cycle of a ~30khz signal.

This means a voltage divider from the load to "discharge" can trigger the 555 any time the voltage is too low. A small capacitor can delay and smooth this a bit. The "thr" pin compares to 5V and the usual "one shot" action can set the on time.

You're right. O2 is molecular oxygen or diatomic oxygen. Ozone is triatomic oxygen. It's technically molecular oxygen, but we usually reserve that for O2.

It splits oxygen molecules. Oxygen binds to oxygen to make O2. Breaking that bond makes 2 free oxygen atoms. Those free oxygen atoms will oxidize another O2 molecule, making 2 O3 molecules, which is ozone.

Far from being healthy, ozone is a toxic gas, its ability to react with microbes in the air also allowing it to interact with, and damage, tissues in the human airways. In fact I conducted lab research into this toxicity some years ago. For example, the US EPA states: "When inhaled, ozone can damage the lungs. Relatively low amounts can cause chest pain, coughing, shortness of breath and throat irritation. Ozone may also worsen chronic respiratory diseases such as asthma and compromise the ability of the body to fight respiratory infections." I would therefore definitely avoid the use of ozone generators in any attempt to purify air as a means of improving one's respiratory wellbeing.

Terrible looking solder joints all over that PCB. Probably used the sh**ty lead free solder because most of those solder joints look dry and bumpy. I agree that it's a weird circuit design. Cheap looking too. But an AWESOME video upload as always Big Clive! Thank You!

That's not a lead free solder problem. It's bad technique. That's what SAC305 looks like when you are sloppy. Have to use an appropriate tip, appropriate temp and be meticulous about keeping the tip clean. None of that will slow down someone that's gotten the hang of the stuff but it does require giving a shit about quality of your work.

Oh I'm sorry. I've never used lead free solder (or SAC305 as you mentioned) in the 41 + years I've been in the electronics industry, but what ever the reason is for these lousy solder joints, this should not have passed inspection. I'll have to try out the lead free solder sometime and see how it works. Probably won't bother with it though.

@@JayH7745 SAC305 is one of the industry standard lead free solders. Similar to working with the lead based silver bearing solder of old but higher heat to get good flow. Works amazing when you need something that'll shield the joint from ambient RF and as I learned in a recent project can actually weld galvanized steel with a seamless (looking) joint.

Why use a 1K pot in parallel with a 1K1 resistor, instead of just using a 470R pot? Overall, it seems fairly well-designed for a cheap unit of dubious value.
