Old shoe deodorizer ozone unit (no microcontroller)
This unit's quite old. I got it a long time ago to help dry and deodorize my work boots.
In the end, the secret to keeping my work boots fresh was a tiny pinch of fine powder boric acid, which kills all fungal stuff stone dead. (including athletes foot).
The construction of this and it's circuit design seems fairly sensible though. There's no microcontroller, so everything is done with discrete circuitry to add "features".
The high voltage section has had the number scrubbed off its chip and black resin painted on some component identifiers, so it seemed a good idea to reverse engineer it as an act of defiance.
If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:-

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

zapping-a-scotch-egg-with-245v
Please be aware that this video involves the use of exposed live metal connections and should not be copied, as it poses a risk of electric shock.
This time it's the classic British snack, a Scotch Egg (hard boiled egg surrounded by sausage-like-stuff and crumbs.
The initial current peak on this was quite high, with a dissipation of over 2kW.
When I mentioned the uneven heating of the egg in the video I meant to say that the white had heated up, but the yolk was still cool.

inside-poundlands-4000mah-power-geek
Right, let's get straight to the point here. We're talking Poundland mAh which aren't quite as big as a real mAh, but aside from that this power bank is actually really quite cool and VERY hackable. (With room for naughty circuitry if desired.)

quartz-clock-pendulum-movement-teardown
I wasn't expecting the circuitry in this unit to be so clever. It's using standard discrete components, but in a very clever way that allows the coil to push and pull while also sensing and synchronising with the pendulum movement.
It's worth buying these movements just for the pendulum kicker module.
Here's a generic eBay search link to the UK site:-

If you see a listing that you like but want to buy it from the com site, try changing co uk to com in the URL.
Target price is around $2.

AIR "
air-freshener-hack-gone-wrong
I may or may not have had a slight incident involving LEDs and 240V.
I quite enjoy just randomly modifying things for no particular reason at all. It's very therapeutic to do something with no real purpose. That's what I was doing here, until I inadvertently added some excitement.
When I smooshed the LEDs in to make way for the bottle, a solder spike pierced the other conductor. It was a one in a thousand chance with quite a few variables.
The reassuring crack was an LED demonstrating their excellent abilities to break high current faults in a controlled manner.
When I replaced the LEDs I cropped them down in size to leave room for the wire.

WHAT'
what-s-in-the-little-red-box-on-some
With the increasing popularity of the mini lithium jump starters for cars, there seem to be some standard components appearing. One of them is this set of plug-in leads with that mysterious little box on one of them. So here's what's inside.
I've not taken a look at a jump starters yet as I don't have a load high enough to test them to their often dubious specifications.
Note that there were two types of package in the unit, one with a rating of 40V and one 45V.
Jerry Korner has done some tests though, so here's a link to one of his test videos. https://www.youtube.com/watch?v=aRyU50M0cJU
It appears that there has been a recall on some of these leads due to the exact scenario I described of overcranking and causing the diodes to fail short circuit, followed by rapid failure of the lithium pack. http://www.cyntur.com/recall

usa-110v-fridge-sanitizer-reverse
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.

A longer than expected video with Kevin and Juan trying to identify mysterious chemical flavours added to an unflavoured liqueur base while answering questions asked by the Patreon posse.
There was a bit of a storm blowing outside which may have been affecting the microphone, which also seems to have a noise gate.

inside-a-tungsten-moonflower-disco-light
A look inside a common retro disco light, and how it uses a single lamp to generate lots of sharp beams of light that can either be static as in this unit, or rotate to the beat.
Although very inefficient, these simple lights put out lots of very sharp beams of light, so they dominated the cheaper end of the disco market for decades.
I was a bit under the weather while recording this video, so I may sound a bit hoarse.
I meant to say "Safety Extra Low Voltage Equivalent" (SELV-equiv) when I described the electronic halogen transformer. (Also known as Separated Extra Low Voltage Equivalent.)
The simplest way to understand the operation of this effect is to imagine that from various positions in the room, looking through the lens will show a reflection of the lamp's filament in one of the many small mirrors. (Don't actually look directly into high intensity light beams though.)
The reference to the capacitor stopping the power supply from blowing up is the tendency of the circuitry to become more sensitive to mains transients when hot. Extra external filtering was often added for electrical noise reduction to limit emitted noise and also try and reduce the risk of power supply failure.

mcdonalds-mcstrobing-mcdownlight-mcfix
Not gonna lie - this was actually a very clever fix until they can get the light fixed or replaced.
Personally I'd have lifted a tile and disconnected it, but this is an easy fix for the non technically inclined.
When one of these lights starts strobing it can make the whole surrounding area very unpleasant to be in.
