Ozone created by the high voltages inside the TV used to be a smell many folk would recognise. I wonder if it still is
I can remember that smell from the high voltage test cells we had at EEV, the anode voltages for the valves under test were extremely high and for safety there was a crowbar across the busbar whenever the door was opened.

I had taken a couple of jolts and thought “ it’s only 12v
Vehicle electrical systems can deliver very high current if you short them out and more than enough to disolve any ring, watch or jewellery you might be wearing and the reason stuff like that was often not allowed to be worn. To this day I still do not wear a watch or any Jewellery.
 
Just wondering what precautions would be necessary to try this safely - for the benefit of those who might be thinking of trying it anyway. If the damp wood was placed on an insulating surface, perhaps glass or plastic, and the probes were attached before switching on, would that be adequate safety measures?

So many people who thought they knew what they were doing, and were doing it safely, have been electrocuted or at best, horribly maimed. Both the AWA in America and the AWGB (Association of Woodtruners of Great Britain advise against it, and no woodturning club in the UL permits demonstrations or experimentation with Fractal burning.

The practice uses high-voltage electricity to create lightning-like patterns. At least 33 people have died attempting it since 2016, according to the American Association of Woodturners. A Wisconsin couple was electrocuted attempting a popular but dangerous wood-burning technique, law enforcement officials said.

Fractal burning, the controversial process for using high-voltage electricity to create designs in wood, has claimed the life of another man in Pennsylvania. A Lycoming County, Pennsylvania, man was pronounced dead Tuesday morning after an apparent electrocution accident while he burned designs into wood using the fractal design technique.

Sadly, since the AAW Board adopted its policy on fractal burning in 2017, there have been thirty-three reported deaths directly attributed to fractal burning, and an unknown number of injuries and close calls.

A MAN electrocuted himself while attempting a “dangerous” wood-burning technique in his garden workshop, an inquest heard. (June 2017):

Mark Sayer, 43, suffered a fatal 2,000-volt shock while using a high-voltage current to burn lightning-bolt patterns into a piece of wood with equipment he had built himself. He then fell to the floor where his clothing was ignited by an electric heater, causing a fire.

The inquest at Oxford Coroner’s Court on Thursday last week heard that he was likely to have been killed when he made contact with the equipment, which included jump cables, crocodile clips and a microwave transformer.

Mr Sayer was the estate manager for the Badgemore estate and lived in a cottage in the grounds with his wife Jade and their two sons, Hudson, seven, and Mackenzie, four.

Sadly, not only was his wife widowed and the children left fatherless, they lived in a tied cottage which went with her late husbands job, which they'd have to vacate.

As to wearing rubber gloves, they'd need be insulated to 2,000 volts.

If part of your body (or even your clothing), touches the wood, (which will in fact be conductive due to the moisture content (otherwise it wouldn't burn), that would kill you. It isn't just the voltage, but the current: "It's the volts that jolts, but the mills that kills". (milliamps).

At least two of those electrocuted were electricians.

Seems to me that it's just one more way to prove Darwin's theory of the non-survival of the stupidest.
 
Could make your own headstone while at it ☹☠

Ignition on even quite ordinary cars now quite enough to kill you, let alone some of the stuff under the bonnet of an EV.

Now there's an idea, plug in a couple of cables into the ev car or wall charger, instant Fractal Burning device.
(PS: it's satire, before you all jump on me ☠️👻💀)
 
I fully agree with those who say it is dangerous, and I am not thinking of risking it myselsf but I was asking about ways of making it less risky for those who might still be tempted, despite the dangers. I am sure there will still be some of those out there.

Maybe a preliminary visit to your solicitor to make sure your will is in order.

I made one a few years ago, which no-one else is allowed to use. Part of the problem is, I think, this attracts arty-farty-crafty types, who are not known for their knowledge of physics or a systematic approach.

If you’re the type who doesn’t follow a recipe or measure properly when cooking, forget it. If, like me, you might use a timer when brewing a cup of tea, and have your spanners arranged in size order, still don’t do it, but at least see below:

Big Clive’s video is pretty good. He suggests it could be made manageable with an interlocked cabinet, deadman’s switch, etc., and a neon sign transformer, which are current-limited.


Read the top comment, from a lineman who got a 13.8 kV shock. Quite a haunting description of what it’s like to survive such a thing.
 
from vaguely looking into the subject a few years ago I was under the impression there was a moderately safe, expensive, way of doing a lichtenberg etching (I'd a ssumed an over the counter system) and a dangerous, cheap, way to do one, namely with microwave parts

Sorry, but it's so hard to read your posts in that font colour you use.

I used to work on high voltage systems and the only piece of advice I will give on an open forum is that you shouldn’t attempt it as it is vey very dangerous, especially without any specialist knowledge and training. The consequence could be death.
 
I think there must be enough comments here now to dissuade all but the most determined of people.

Fergie307 mentioned ensuring your will is in order. Reminds me of the time we visited an aircraft museum in North Wales. There was a book on display telling people how to build their own aeroplane, written about 1920. The first instruction was - make sure you have life insurance, and have made a will.
