Teardown of new Airwick essential mist unit 

I am much more impressed by a Carcinogen warning sign on the "fragrance" bottle.

@@NGC1433 Many vitamins are deadly poison when overdosed. Dont drink the bottle of fragrance and youll be fine.

@@drkastenbrot Your lungs aren't immune to cancer.

Heater removed after all the fires and meltdowns I think.

@@Andy-df5fj My point is that healthy substances can be deadly and dangerous substances can be harmless depending on correct use.

Thanks. I was all set to Google that and you saved me the trouble.

And that's why we all love him so much. :) Clive - the poet!

.... Wonder Woman described her date with Superman that way !

IsoPropyl Alcohol for those who do not know. I'm still laughing as I type this.

Chaotic good. The best kind.

I keep thinking that “IPA” is going to give you the aroma of beer, it takes me a moment to adjust the context. 😄

The Capacitor and 100 Ohm resistor basically gives the microcontroller a Voltage based on the mean current flowing through the 1 ohm Resistor. Maybe this is used to tune the frequency to the resonant point of the Piezo i.e. when the most current is flowing. Just like a Maximum power point tracker for Solar panels would do it

"IPA", Ultrasonically vaporised paraffin might be interesting, baby oil is basically an ultra refined type of paraffin.

I recently found one of those in my basement behind the freezer, must have been plugged in about 15 years ago. It was all brown and crispy and fell apart in my hand. A fire risk I never knew I had.

@@tncorgi92 that was the mouse’s central heating system 🐭

@@robert_g_fbg could be, at one time we did have a crazy moose loose aboot the hoose.

@@robert_g_fbg Once I was cleaning the coils of a fairly new modern fridge and found a Wacom Tablet nest.

Replace the aroma liquid with cat urine and hide it in a random spot in your favorite bureaucrat's office.

@@tncorgi92 Hide it inside of the air conditioning ductwork with the cat pee container. Would take ages for them to finally locate that "bad little kitty". Ha! I love it! Fred

Well, now that you've put the idea out there it will be marketed in the most annoying aroma/music combinations possible. "That Smell" Lynyrd Skynyrd "Smells Like Teen Spirit" Nirvana "Kiss Me Where It Smells Funny" Bloodhound Gang "What's That Smells Like Fish" Blind Boy Fuller

Those first two tunes go well with extra toxic liquids.

A little ditty about Jack and Diane?

I don't think they actually need an extra disc to do that. Maybe they can modulate the power like a musical tesla coil.

That's nice to know. I prefer if an air freshener only runs during daytime hours anyway.

I was. I expected it to be a blob, crystal switch transistor and inductor/transformer.

Moving parts fail !piezo elements are moving ,just like your speakers in your Hi Fi .They eventually wear out .A properly made resistor in ceramic can last a lifetime !Platinum wire wound,nichrome they last a hell of a long time .

I hear you!

100% this. I bought one a couple years ago... I hate all the aromas. Why can't they just have simple single scent aromas (orange, lemon, vanilla, apple cinnamon, etc). They always seem to be strange blends "cucumber melon pine" or some other nonsense.

"Yet people are unwilling to wax." Don't blame them, that hurts. Plus I've not much hair left on my head, I want to keep the rest of it.

dont worry about the anti-waxers, the rest of us can enjoy candles without them

@@frogz I'm not an anti-waxer, i'm just wax hesitant.

have you tried paraffin? honestly it is better and has better priorities than bees wax and soy wax for candles but blends are fine

Somewhere there's a small child that never got to see their 12th birthday. Chinese manufacturing being what it is.....

I bought a brand new guitar amplifier for super cheap because it didn't work. When I opened up the back panel I found the wire connector had slipped off the rear of the power entry receptacle. 2 seconds to fix and now have a great amplifier the neighbors hate 😊 Too many things get tossed these days for need of what is often an easy fix.

@@pmpwiz hear hear well said John

Same here, but watching this stuff makes me feel like I’m clever.

@@norfolkngood244 nice one!

That is really weird! What on earth could that be on there for? Now I want Maltesers. They tried to get them out here in the US a few years ago, and I was buying them every chance I got. They seemed to have given up because I can't find them anywhere now. 😭

It’s like are kids getting dumber or something? It’s pretty sad that people got by without stuff like that back in the day, And now everything is childproof because of the lack of parenting.

Nice catch. I wonder what that is about.

It was really tricky getting a good picture. I really needed a large area of black backdrop and some colored lights.

Watching all of Clive's videos gives you a B.S. in electrical engineering

@@nyetloki B.S. means Bachelor of Science this time around, right? 😊😊

@@TrondBørgeKrokli maybe it does maybe it doesn't

@@nyetloki Ha, funny. (* chuckle *) 😁

Certainly wish I'd had teachers of Clive's calibre when I'd did my TEC (Electronics) 40 years ago. Because my college lecturers were crap. Hand out a sheat of bander-printer copied handwritten notes, spend the lesson reading it out in monotone. Some calculations for homework.

I'm leaning towards output FET drive requirements.

Yeah, it's also been pointed out that the parasitic diode in the MOSFET will potentially cap the microcontroller rail to about 0.7V above battery voltage.

I think it's to prevent brownout circuitry of the MCU to kick in and reset the show.

@Shawn Stafford Yes, though you would have to replace the control micro with something else to drive the piezo transducer.

@Shawn Stafford 9:58 the microcontroller turns the power on and off to the atomizer piezo really fast to get it to actually vibrate and throw the liquid droplets into the air. You'd need to recreate this circuit

In hindsight, it does have a daily timer function. Well spotted.

Ah makes sense, thanks!

Yeah, these do an on 8/off 16. The original model did, too.

Yeah. That was quite annoying.

So glad it wasn't just me.

Morgelons ;)

Came here to say just this - if I can put my own fragrances in, then I'll have one. The what and how are all I'm missing!

@@nabarnes exactly my thoughts too, can we make our own smells Clive (not those kind of smells!)

you can but i've found that the oils need to be the soapy oils for soaps, not alcohol based oils for perfumes/fragrance oils, if anyone can figure out how to get them to atomize the heavier oils please let me know! maybe some glycerin? kuumba made amber sandalwood...... took me YEARS to find this scent after getting a candle with it originally

I want one with the scent of selenium rectifier^^

I had some wisps. Not very reliable. I'm hoping to find one of them to reverse engineer it.

Isn’t the older one called the Wisp?

I'm not sure if it has any way of sensing. Most of the piezo disks have a consistent resonant frequency.

@@bigclivedotcom Usually, crystals running in resonant circuits do run at a "fixed" frequency.. but this crystal has a varying load, and a varying supply voltage. With the voltage regulator helping with the voltage issue, then it comes down to the physics of the crystal, diaphragm, wick etc. Thanks for all you do, including your replies... It's nice to have a place to look for something stimulating to watch.

Yeah they are quite slick and apparently pretty similar.

The liquid has to be a specific viscosity. The common mini ultrasonic wick humidifiers use water.

Maybe a fan of Android operating system?

Yes they did.

They have three levels of aroma.

The Aroma of that room would be pungent though and probably would keep you up lol

@@BLAZE13011 I wonder if it would work with water...

The mini USB humidifiers with piezo disks and wicks work with water.

I've tried a few things. The liquid type and density is quite critical for the best results.

@@bigclivedotcom back when I used to vape (5 years ago) most flavour was carried by pg as it is a lot thinner than the fog producing vg and it will thin down so it could be possible to roughly find the viscocity of the original fluid with blotting paper and a dripper bottle to get a general spread size pattern you can use as a template when mixing the correct runniness of the fluid for d.i.y refils with whatever vape base flavour you required .. (this idea sounded better in my messed up nut before.) All thone best to you and your brother (you pair are better than Any double act to have exsisted anywhere inc TV. ) Have a good 2022 Clive & Ralfy.

I see it the other way round. The device is designed for the stable 12V supply and switches it off to conserve power. Its a very clever and cheap way to get both stable step-up power and super low standby current.

"When the switch on the control panel is moved from the off position to either of the 3 settings (min, med, max) the device is turned on and will run for 8 hours unless switched off. By moving the switch to the off position during the 8 hour cycle will terminate that cycle. Once turned on again, the timer will reset and a new 8 hour cycle will begin. Changing the intensity setting will not reset the cycle." Mark 1 FAQ

Not only in the 1990s. The "trend" was still alive and sparking three years ago when I was last in China.

The ultrasonic fog generators don't give you a shock. It's the modulated ultrasonic energy you feel.

@@bigclivedotcom Ah, but the one's we get over here don't have the added delight of mains (or higher?) sparks around the base, which is being washed with the foul water that drips from the "fish tank" at the base of the "magic pesant aroda disposer" (I quote from a photo of one such device in a food store window) that so obviously had a faulty mains lead.

@@bigclivedotcom I get the “no shock” mentality you have since a lot of people know it and myself as an electrician had it drilled in to me that 0.05A of current is all it takes to kill a human. I concede for an adult now you may not but I would have been 7-10 sticking my fingers in (that sounded wrong) and my friends and myself would routinely get shocks. I also remember getting shocks with the same friend that adults around us couldn’t feel from an arcade machine- every time you held a coin to put in, you would get a DC shock till you let go and dropped it down the coin shoot. I know I will get shot down here but as an electrician since just before my 16th birthday, I know what a shock feels like and I guarantee we were getting shocks off that fruit machine (in adulthood, I reasoned a localised earth since this was in Spain, probably neutral WAS earth). I remember my mother (in dressed up clothes with rubber soles) not being able to feel what i along with my compatriot has been describing “like a shaking feeling inside yourself, that makes your teeth jitter”. I can remember it clear as day. That was my very first shock, by no means bad, iv had many worse no RCD single phase shocks as a young teen but it always stuck with me that DC shock feeling from the coin shoot and the same feeling from these smoke machines - total vapour salesmen! Sorry couldn’t resist. As an adult I will always listen to my kids in these matters if I am blessed enough to have any but in my day it was “what? You can’t put money in the machine?? So I’ll just go an stop giving you money then will I??!” I deduced that A adults have higher skin resistances and that B as I said above, my mum checked when all dressed up in rubber soles shoes- not bare wet feet like us boys reporting this. I wonder whether the ultrasound person piezoelectric supply is not also producing the same effects since as I’m sure Clive you will be aware more than anyone, for a “wow!” Result you need to be putting in a reasonably large amount of power by means of a power brick I recall. Now if a Chinese powerbrick alone isn’t scary enough, we introduce water, children’s small fingers into said smoke producing water. I haven’t seen them since day 1998ish - making me just turned 8 years old so I might be totally wrong but I’m sticking by my guns with this one. Edit:- oh and I am 18th edition trained and completed my HND over 13 years ago and my modern apprenticeship around 12-13 years ago.

It is. I didn't think of that feature for the crystal.

Glade is owned by SC Johnson. They are competitors of RB, who make Airwick.

@@bigclivedotcom Thank you! I was assuming that it was just the fragrance itself, such as an alcohol solvent perhaps. I see you had to put fuel oil in it to do that though.

That's a good point. I guess it's only going to be the full 5V with fresh batteries.

It might be OK for creating a light mist. I think I'd rather use a vape for low level controlled direction haze though.
