Inside a cheap illuminated smoke machine.

With a bit of work it could be converted to use pink "grow light" LEDs.

The oil hazers use a technique called oil cracking. They blow a stream of small bubbles through a tank of light mineral oil like baby-oil and when the bubbles burst at the surface they shatter into tiny droplets of oil. A controlled air flow then lifts the lightest haze of those droplets up into the path of the main dispersion blower that pushes them out into the room. The haze you see is actually a very fine mist of oil droplets. These hazers are commonly used in TV studios with tanks of CO2 so they can be run almost silently for long periods of time.

I guess they dont do.... pink! hahaha! nice teardown though!

Only rate-of-rise heat based detectors. Basically a thermistor that is used to sense a sudden increase in temperature or a preset upper limit.

Very happy to see something like this being taken apart. (got a bit boring with lamps and such xD), I recently got an Antari HZ-100 cheap, because the smoke output was very low. After a bit of ultrasonic cleaning of the head, it came back to its full output (all 3 nozzles working). The HZ-100 is a compressor based hazer, and sucks the fluid up with the venturi effect of blowing air through a small nozzle..... but how does the fluid actually turn into haze? Is it just the small hard air blasts evaporating the fluid?

Thanks for the review. Are there special smoke/fire detectors available that don't get triggered by such fog machines?

I read on here people having problems with audio. As yet, watching on my phone, laptop and when I cast it directly to my TV (Bravia downstairs and a cheap supermarket one in the bedroom going through a Freesat box) I'm yet to really hear any clipping or any issue whatever with the sound. I also listen through cheap headphones at work and Bose ones at home. Again no issue at all. To be fair it could sound like you had your head in a dustbin, as long as we can understand what your saying, what matters most is what's happening on screen.

Farnell themselves stock a range of 220-250V 10A rated momentary switches, if someone felt inclined to replace the rocker switch on the "remote". I am guessing re-using the same switch as the main unit might well have had a BOM cost consideration, as well as the rating consideration.

You mention the audio in the video, this video seems to have much more clipping than I have noticed before (I noticed before you mentioned it ;)

Kelvin

You said "small orifices".

I tried that mic first, but I get the feeling it's not operating within the phones ideal input signal range, as it seemed to be squishing the sound a bit. There's always a bit of experimentation involved in getting the sound right.

Try the teapot mic, Clive. I've had good results with a similar mic on the Moto g7 Power phone, where the mic was clipped 2 or 3 feet from me and my bench, but picked up all the relevant noises well.

Andy Brown

No. Because the amount of clutter still fills me with shame.

Big Clive

It's "medical" so commands the usual inflated pharmaceutical costs.

Big Clive

Hey, did we finally get a glimpse of the surroundings of 'the bench'?

Paul Schuur

Happy New Year Clive. Not bad for the price, a nice cheap party effect that is "safe" nice..

Richard Boyce

Wow, Ozium isn't cheap!
