Sparks and sparkles. What's there not to like?

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….
This was arranged as an exclusive for Vice magazine who asked for a new project to feature.
By the way, no photoshopping anywhere on this site. It’s all what the camera sees.
This is my interpretation of Rodin’s classic sculpture, the “Thinker”. Topics include:


Background

Thinker

The original sculpture of the Thinker was by Rodin started in 1879. I wanted to convey 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”.
I decided upon a real life posture like the Thinker with a lot of electrical activity around me with sparks onto my body.
I wanted to do something new that also challenged the boundaries and that is new to the internet. I used my established techniques of long exposures and a moving rod trailing sparks with an “eye of Sauron” effect. The aim was to have a semicircle of sparks over my body while in the “Thinker” pose.


Mechanical and High Voltage Setup

MTsideViewTCarm

Above shows how the output of my 4 inch diameter Tesla coil is directed by a rod so that it can spark onto me sitting on a chair.

MTHRSparksUncovered1000 MTHRStreamers1000 MTHRSparksFlames1000

Above in the left photo you can see sparks onto a wire frame. In the center photo the voltage is cranked up giving large streamers. The right photo shows some early attempts at a mechanical linkage with part of it burning up which is the orange glow.

MTFoldachair1MTFoldachair2MTFoldachair3

Above is a sequence of 3 photos to show the effect of the mechanical linkage to direct the sparks around the body. I am not next to the sparks, this is a long exposure with an initial flash of me in the chair. I then get up and run away and the Tesla coil is turned on. It simulates a double exposure to demonstrate the position.

MTRotArmWireBanjo MTDayRunThreeQuarters

Above the left photo shows a long exposure of the sparks above forming a (sort of) semicircular ring of sparks around the chair where I would sit. Very untidy but a better linkage in the right photo demonstrates the principle better. The frame is just to simulate my height and seating position.

MTsideViewTCarmOperatorClose MTsideViewTCarmOperatorCenter MTsideViewTCarmOperator

Here is how an operator will direct the arm in a semicircle. “It ain’t fancy but it’s chee-eep”. A black backdrop has been added.


The Face Mask

Allowing the sparks to contact my body or face directly is not safe of course. A single spark that gets past the defenses would throw me to the ground in intense pain like a Taser shock. Multiple sparks would also stop me breathing and be fatal eventually. Hopefully my loving wife at the controls would turn off power before then.
Sparks in close proximity to a body are impressive. I have used a Faraday cage before (the popular Dalek cage) but I wanted something more direct. Sparks need to contact metal and not my skin. They also must have a continuous path to ground preferably a broad one with no joins or potentials for failure to prevent any voltage drop developing and causing a shock.
I considered a number of options. I tried copper foil and made a mask and headgear of this which was effective and safe but crinkly and not cosmetic. It worked though and high voltage to my head was not noticeable.

MTheadMould MTmaskWigICsparks MTmaskWigICPoseDay

Above the rather stiff and fragile copper foil doesn’t mould to a head shape well. It does make the sparks safe but looks like a horror mask. Long aluminum straps go from the mask to ground level. Let’s try something better.

MTFacemask

Above the fine wire mask which is based on the simpler version that I used successfully in the pool. It uses very fine strands of stainless steel wire. It is designed for safety and minimal facial coverage. This will be joined to the suit.


The Safety Suit

MTmultiplefabrics MTblackMetalFabricSparks

Above I did try various metallic cloths without success when subjected to spark testing. Despite having metallic looking thread they are poor conductors.

MTAlfoilArm MTAlfoilStockingArm MTArmICsparks

Above shows my hand covered with foil and a stocking and does seem to take sparks without problems. I eventually settled on builders insulating foil. This is a foil backed by fibreglass and plastic and is thin but strong enough for me not to be able to tear it by hand.

MTFirstFoilSuitShotSingle MTFirstFoilSuitShots

Above shows me simply wrapped up in the builders foil. First with tentative low power then higher power prolonged shots. No sensation or discomfort at all. So the concept seems to work. Now just need to make a better suit.

MTsuitArms600 MTsuitArmsLegs600 MTsuitWig600

Above shows different stages . The arms and shoulders were not bonded to the main suit but were in good contact with the body aver a wide area. The wig is not ideal and really needs a haircut. I couldn’t light it with sparks so fire risk seems low. The hands look a bit artificial but everything else is safely covered.

SilversuitWornuncovered SilversuitWornCovered

Above shows a later tidier suit which is a (sort of) fitted with a zip up front. Much easier to get in and out of so gets more than just one use like the old one which had the silver surface ruined by the tape. It has lost a lot of the silver when you look at the inside but most of the silver squares are still joined at one point. OK for this TC but not the larger one I suspect. Still very hot to wear. This was not the one used for the pictures below though.

So time to get setup.

Above in the left photo is my son Michael (previously seen clapping smoke rings and sitting in the TC on the car) who is controlling the linkage. In the center photo I am setting up the sidelighting. In the right photo, Jane sets a sparkler.

MTFaceFrontClose

MTHRpentagramKnee

Above in the left photo you can see sparks to the fine wires of the mask while I “think”. In the right photo I thought it looked better to get a sparkler in the picture attached to the tip of the sparking rod. Sparks strike my knee without sensation.

Now time for some shooting.


The Thinker and Variations

MTHRnoSparkler1000 MTArcsEnlarged

Above, you can see sparks the effect I intended as well as a close-up of the sparks.

MTSparklerOnly1000 MTHRcandles1000

Above in the left photo you can see the effect of just placing a sparkler on the end of the rod to add more color and action. Throwing a few tea light candles in helps as well. My face is rather obscured by the sparks though.

MTHRpentagramFaceForward1000 MTfootArcs

Above in the left photo you can see some fluoro tubes which light up themselves with tea light candles at the ends of them. It is a better photo as the face is not obscured. The pentagram of lights seems to be an awfully mixed metaphor. The right photo is one of my favourites and shows sparks from my foot onto the ground.

MTShoeBurn

If you play with high voltage, make sure your rubber shoes don’t have holes… This was getting uncomfortable hot and I had to wriggle my toes which causes some foot motion blur.

One might speculate that with well over 1 million views that it may have been seen by more people than say Rodin’s original in his lifetime. (1 million people = 100 per day for 30 years). His sculpture became more popular decades after his death. Of course this might just be a reflection of the pervasiveness of the current media rather than my artistic ability.

Aus Got Talent – Setup

The Tesla coil sparks are stopped by the earthed protective screen.

This is how my 2011 performance for AGT was developed from a backyard Tesla coil demo.
The various TV and other videos are on the Australia’s Got Talent – Videos page.
But here is a 7 second animation of the 2 minute act which I will refer to.

Australia's Got Talent

The main stunts I did are these:

Burning CD's for Australia's Got Talent Channel 7 Promotional Photo

Left photo shows me holding a wooden rod with burning CD’s.  The wooden rod that I am holding goes up in flames. Extra sparkles came from burning steel wool. The right photo shows one of the promotional photos with sparks onto a metal cage that surrounds me .

So how did this all happen?

I was invited to perform in the auditions of Australia’s Got Talent in Perth, Western Australia which screened on May 10th Channel 7.
Suzanne (exec. producer) and Paul came to do some preliminary video at my place on November 24, 2010. Auditions were performed in Bunbury Western Australia of 200 people in the local Entertainment Centre and they came to my place afterwards. I was looked up specifically due to the top 5 success of “Arc Attack” in theAmerican equivalent show. This was the first level audition to see if it gets to the full auditions held in Perth in 2011. See the official AGT site.
The result was that I made it to the televised heats in March 20th in the Perth Entertainment and Convention Center. There were major issues with the venue, power, earthing, interference prevention and public liability.

AGT Paul and Suzanne
Firstly the music. An original soundtrack was done by my son, Michael Terren who is an 18yo pianist and composer studying at the West Australian Academy of Performing Arts. The music has a pounding industrial theme and runs for 2:17 mins.

Resonant Air-Core Transformer (Australia’s Got Talent) by Michael Terren Some of his other work is here.
Secondly, crowd protection and iterference reduction in close proximity to judges, microphones and video cameras was achieved by the use of fine wire screens.


AGT Judge Screen 3.5m

AGT Judge screen as planned

The judge screen is shown above. At 3.5m from TC center, there are strong sparks to the screen but I am quite safe behind them. For the judges (Kyle Sandilands, Dannii Minogue and Brian McFadden) I have chosen a more conservative distance of the screen being 5m away as shown on the right.
Much other equipment was constructed for this show including a bank of 6 arc welders to be used as needed for voltage isolation or ballast, and two 3 phase distribution boxes. Also extended black backdrops and a vast foil earthing system / partial Faraday cage not to mention a new capacitor bank and power factor correction.

Early setup

AGT final setup
Above left is the repositioned enclosure and center shows one of many discussions with the safety officer, Joshua. The right photo is the final setup ready to go. Note there is a network of suspended wires completely circling the TC for protection and reduced fields for camera safety. On the day I decided not to go with the rigging of an elevated shield in view of the height of the roof. Note the large foil covered area of about 50 feet which is the RF earth which connects to all the elevated wires and frames. There was no direct link to the pavilion building earth but there may have been through some expansion joint covers. The mains earth was kept separate. I ran the ARSG gap and blower gap motors through back to back arc welders as isolation transformers. There was no clear return path for capacitative currents induced into the 50 foot ceiling. There was no ground available for over 100 m that was not a mains ground. Using this method of a “Faraday cage” open at the top, there was no evidence for interference with sound or cabled video cameras. It was close enough to have sparks within perhaps 10 feet of the judges (it could have safely been a lot closer with my design – tested to within 2 feet). The grounding with downwires from the frame allowed confidence in preventing capacitative voltages appearing on equipment and operators. It is my belief that this is more important than RF interference. Certainly this was as close as my operators have been and no tickle from holding the variac!

Exploding Stuff

A Terminator like picture of steel wool electrically exploded.

Exploding stuff is simple and fun. Just put the conductive stuff to be exploded across the capacitor output and it will vaporize (unless it’s a hot dog).  The capacitor bank is discharging 5 kJ in to some steel wool for more impressive sparkler effects.

Quick Tour

This bank of 3 pulse capacitors fires into some steel wool.

OK – a 2 minute tour.

I am mainly a High Voltage and Tesla coil enthusiast. I like big sparks.
I also have hundreds of other projects here which involve electrical, pulse power, laser, magnetism and other weird stuff. All documented with thousands of photos.
Some of the high voltage photos are unique artistic creations and have appeared on TV around the world.

Right that was 10 seconds….

Tesla Full Bright 1000

Best projects:
Check out a 16,000 Joule 12,000 volt capacitor bank for hugely powerful discharges. Half a gigawatt of peak power used for Can crushing, coinshrinking, exploding wires, exploding watermelons and many other experiments. Perhaps look at the Xmas tree 2009, the Red Alert Tesla coil, Jacob’s Bi-ladder, making liquid oxygen, Discovery Channel videos of my stuff, my new record spark length of 11 feet, multicolored sparks, the Tesla Envy video – up VERY close to huge sparks, Dalek cageswimming with 100,000 volts, video of car theft protection, “Eye of Sauron” and a sparks for beginners project with only 3 components.

 

Other capacitor banks with electronic switching drive projectile devices such as a rail gun and coil gun. Other HV stuff stuff includes voltage multipliers, Van de Graaff generator, Jacobs ladder, lifters and other high voltage supplies. Various lasers including a homemade ultraviolet nitrogen laser, NdYAG, HeNe, Blu-ray laser, and CO2. Also magnetohydrodynamic drive800 A spotwelder, huge smoke rings, liquid nitrogen, ferrofluid, magnetic levitation, miscellaneous electronic projects and a few half baked ideas…
I did a modern interpretation of Tesla’s famous photo with his wireless light globe. My performance in the heats of Australia’s Got Talent. Highlights in recent months include work on a proposal to NASA to view my light from Space. The light is used on the World’s brightest LED bike light (below) and World’s brightest portable LED flashlight . Also see the Xmas tree 2010. Had a visit from SteamPunk enthusiasts for a night of Tesla goodness.

That’s another 60 seconds for speed readers.

So spend the next 50 seconds flipping through some photos and you’re done…

Strange High Voltage Water Surface Effects

Water Arc 4 Green Striated 2

Pass a lot of high voltage DC current onto deionised water and you get remarkable colourful patterns at the water surface.

                          
 As the deionised water became conductive enough to sustain a higher current , the faint and feeble spark increased to a power arc to water of about 2 kV DC eventually to the point of making the wire red hot. The first 3 photos all show interesting variation in the surface effects. The green glow is the copper from a hotter arc.
