Ignoring the fact that I can trace my migraines to the vaporized oil carriers of artificial fragrances: my concerns are a bit more tactical. You could put *anything* in that oil container and as long as it has the surface tension and viscosity to wick through to the transducer it can be put in to the air. Personality: I'd rework the delay to be from hours to days, fill it with something that smells like a horrible fart and then hide it in an elevator or office environment.

Essential oil atomizers should be required to have a pet warning on them. These things can cause serious problems to cats, and dogs to a lesser degree. Their airways can be heavily impacted by atomized, but not actually vaporized, essential oil droplets. By contrast, odorizers that just heat the oils and let them evaporate (true vaporization) with no active spraying mechanism are perfectly fine around pets.

A true vaporizer doesn't put oil droplets into the air, but releases the aromatic compounds as a gas, via evaporation through heating. Vaporizers are generally pet safe (except for rare instances of hypersensitive pets). General rule of thumb: If the device does not have an active heating element but does use an active spraying mechanism, it is nebulizing/atomizing (creating microscopic droplets that can float in the air for a long time) and not vaporizing.

Adding a touch of isopropyl alcohol or ethanol to oil can also help it diffuse out easier.

Maybe the transducer is on a springy mounting so it can move more freely? In theory you could get the same effect with less current that way.

Just brought some of these, and it looks like they have difficulty atomising some of the more viscous oils (like the one I tried just splattered a small amount of oil around without actually atomising it). I will have to try with some thinned out oils and see what happens.

You're getting the highest likes to views ratio. Well deserved!!! 👍

I think they made a few noob mistakes. Y1 is a PNP transistor rated at 40V max Vce. They'll get destroyed in no time. They should've used logic gate N-MOSFETs like the Si2302DS, to bypass the BEMF of those coils to ground via their built-in diode, to be captured by a 10uF+ low ESR (Electrolytic or Tantalum) capacitor across the supply. If I needed one, I would buy one and mod it. I use a little fridge Ozone generator. It gets rid of smells without the room smelling like Ozone. But I really like the miniaturization of parts to make this little landfill.

That's a pretty cool device.

Interestingly, they're not available to Australia, except through British sellers ( but the $34.13 postage on top of the $13.72 cost of the item makes the purchase a bit pointless ! )

Quick question Clive, Do you do all your projects to Electrical Standard? Or did you also do "not-to-standard work wich still is more than good enough" ? For my Projects i tend to always do it so nobody can get hurt or die but sometimes i do things like: I know itd be better to solder this connection but i dont have my tools on hand so ill just twist the wires, secure them with a Zip tie strain releaf and put some electrical tae over it. (Low voltage only). Like adapting a different power button onto a OEM Connector for a Mainboard and OEM specific fan headers. Its a dirty, quick fix but in my opinion its more than enough to outlast the PCs Lifetime and User abuse.

Not sure if it was you tube but I had a four second video halfway through. Not seen this before with Clive’s videos.

Any chance to scope the “AC” output of the transformer for frequency and waveform? I seems that they might be using cheaper transistors that switch slower or less clean. Perhaps the transducer does not care or the additional inductor smooths it.

I got a pack of 4 on ebay. Of the 2 I've opened so far, neither have any oil in the black-topped bottle and one had no wick bottle. So perhaps they're being dumped because the packaging got screwed up. I wanted them in order to investigate the driver for another use, so no loss :).

I built a similar kind of AC inverter for my Halloween lantern I used a neon flicker bulb based on a 4047 and they lasted for about a season then the chip was fried...

Whether it runs under the chip or not is not what he's talking about. That trace isn't a superconductor, so as current flows through it, its voltage will drop. If you have a trace 20mm long and 0.2mm wide, with a standard 35um of plating, its resistance will be approximately 49mΩ, so sinking 1A along it (when the transistor is on) will cause a voltage drop of 49mV. Introducing this voltage variation on the power supply pin for the chip several hundred times per second (whatever frequency you're switching the transistors at) can introduce instability.
