Lichtenberg wood burning

[Spectric]

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.

Pyrography.

I knew I had seen woodburning somewhere, just the name eluded me.
