The photo above shows a golden ring of 60,000 volt sparks around my laptop. I reckon it looks like one of those rings of power around a World of Warcraft character protecting it. From what? Viruses of course. Hence "High voltage antivirus" - for PC or Mac.
And I have other versions...
The photo above shows that it also comes in a flame colored 'lite' version. The high intensity professional version is on the right.
Note that as in all my photos there is no "photoshopping". The pictures are all single shots and effects are produced with long exposures. Here's how.
The left photo above shows the ZVS flyback supply driving a 4 stage CW multiplier. It is capable of 5 inch sparks but shown here with half that. The center and right photos show how the rotating setup swings the sparks in a circle around the laptop but not too close to my face (just). The center terminal is earthed and is relatively safe. The 'hot' electrode is closest to my face. There is a bit of motion blur in the main photo because the sparks started just in front of my face. They are very loud and bright and it is hard not to reflexively blink and pull back a bit even when you are expecting it. Being close to DC voltages gives a spooky feeling as the ionic wind blows on you and your hairs stand on end as they charge up. As the spark moves these feelings move across your face.
To create the main picture the following sequence is used.
