The Tesla Coil 4-Inch Ver 1 is the earliest version of the 4 inch diameter secondary coils and is shown here in early grainy low light photographs. How things have changed! Still, a wondrous moment to see bigger sparks for the first time.

Neon sign transformers are the starting point for many beginners Tesla coils. They are a handy 12 kV peak unloaded and 30 mA into a short circuit which is current limited.

This bobtail guards its Tesla coil. An unanticipated Tesla coil danger. These harmless and slow moving lizards have an impressive threat display. A whimsical look at non electrical Tesla “dangers”.

Tesla coils produce high frequency AC which is passed through a diode and capacitor to produce DC. This Tesla coil rectification is a difficult task as very high voltage diodes capable of running at several hundred kHz are not easy to come by.

The second version 4 inch diameter Tesla coil uses much higher power components.

Dr Electric plays Happy Birthday for Nikola Tesla with, of course, a Tesla coil and a piano.
Michael demonstrates a new meaning for electric piano.
Let’s look at the setup. First take a common or garden variety Tesla coil…
Place it on large driveway. Add ladder and cage. Be sure you understand that one you stay in, one you stay up and the other you stay back from.
Add a piano then add subtle electrical protection to protect the fine wood from sparks.
Hastily cover up when rain threatens. But under every rainbow is… ( sometimes a Tesla coil).
An unmanned test flight.
Michael is not at all worried by his first time in the cage – yeah right.
The piano was untouched. It was covered by a fine metal mesh which was earthed, along with the frame of the piano. Also not seen are very fine wires taped in unseen areas to catch errant sparks. These are pointed towards the camera to make them even harder to see. It is still sitting on the dolly we used to get it out of the house.
This setup was a piece of cake compared with putting the piano in the middle of a grassy field for one of my Michael’s piano improvisations a few weeks ago.

This is a long exposure of an ionic spinner with green and blue “neon” fluoro pilot lights rotating on my mini Tesla coil. It shows the corona which is the purple ring of air ionised by high voltage that drives it.

This shows red sparks. This effect is created by taking a normal white flash shot first to give the correct white background, then switching to the red filter and running the sparks for 10 seconds or so while the camera is recording.
It is all one single exposure and is what the camera sees, not a photoshopped effect added later.

This is my take on one of Tesla’s famous photos in which he demonstrated remote power lighting a globe.

A Tesla coil makes dramatic lightning like displays of electric power such as these sparks to me in a Faraday Cage.
The “Modern Thinker” above is my interpretation of Rodin’s classic statue the “Thinker”. It conveys the concept of the modern electrical age with the barrage of electrical interference in our lives. So much is happening and demanding our attention that it is difficult to “think”.
Believe that?. Me neither. I just like making pretty spark photos….
By the way, no photoshopping anywhere on this site. It’s all what the camera sees. Check out the Modern Thinker page for the construction of this.
Above shows “Tesladownunder car theft protection”.
Above shows a Tesla coil with rotating long breakout point looking dramatic on time exposure of 22 seconds. The “Eye of Sauron”. The two photos above have been seen by perhaps 500,000 people worldwide now since Feb 2007 and resulted in well over 100,000 hits to my site. It was featured on some big sites and hundreds of blogs and was also popular in Russia and Japan.
Above is an animated gif showing the effects of rotating the rod on top. In real time it takes 7 seconds per rotation.
Above is my recreation of Tesla and his wireless light globe compared with the original.
No photoshopping – ever.
Above, the Dalek cage. Just what you need to get up close and personal with lotsa volts. And you can even use a phone in it.
Above: How about red sparks?
Above: There are lots of other colors to see in multi-colored sparks. These are single photographic exposures through clear and colored filters in turn.
Above, swimming with 100,000 volts. Sure it’s safe. Tin hats protect you.
Above, Tesla coils with sparks from 2 inches (5cm) to 11 feet (3.3m).
Above, a briefcase Tesla coil and sparks in a light globe.
Above, Tesla coils sparks onto my tongue, driving a string of up to 30 fluoro tubes and apologies to Michelangelo’s Creation.
Above, some unusual solid state Tesla coils on the left using SIDACs instead of a spark gap, centre using a Royer circuit and on the right a vacuum tube based coil and its sparks.
