I have let out hints that I was working on a Tesla coil to simulate the Red Alert Tesla coil. Red Alert was a real time strategy game that was very popular since its release in 1996. It is also many people's only contact with the concept of a Tesla coil. The TC was a major Soviet base defence unit, able to fire long sparks at intruders. It was augmented by Telsa troopers for extra power.

The TC as depicted in RA had multiple toroids and a sphere on top and had coloured supports and could shoot spark over long distances. The sparks were usually white with some yellow ones.

I can make the multiple toroids and have shown how to get the coloured sparks. The other structures and Tesla trooper can be modelled.
The long sparks I am now in a position to show with the first shot below. This was the first major hurdle.
Note that like all my pics, this is a single exposure with no photoshopping.

Now that's truly amazing....

You've done it again Peter,
this one's sure to get about a billion hits!
Great stuff.

How's it done?

I'd call it a fraud - the bottom of some of the sparks are flat and cut-off. You overlaid multiple images.

i dont believe the pic though.. it looks as if the metal garage is closer than the hoop. and as capper said, they look cut off at a few spots.

mentiroso.... hehe

It looks like he dragged two conductive wires/breakout points separated by a non-conductor in the line between the coil and hoop. The same thing used for his ball as it appears.

People regularly call my stuff photoshopped. It still hurts a bit though. Usually they don't bother to read the simple explanations on my site. Although this is not on my site yet I have explained how I was going to do it here or here in Mystery photos. The thing is that this must be easier than photoshopping. Particularly when I have many photos and out-takes.

Span is about 19 feet. The spark is 3 feet not 19 feet and it gets pulled along during the exposure.
I repeat that all my photos are single exposures with only minor adjustments such as brightness and cropping.

Pic 1 is a shorter (18ft) span with a 20 second exposure.
Pic 2 is an outtake. Out of focus and the wire fell off the hoop. Burnt some grass which the kids thought was cool and what we really should be photographing.
Pic 3 shows the spool closeup with the connection to the short length of nylon line.
Pic 4 shows the spool and you can just see the line up to the hoop. From there it joins to a nylon line again which I pull on.

Well Capper, technically it is fake, it just wasn't faked digitally. I agree that it must use the wire method.

It still looks awesome though, proper job TDU smile

It obviously is not hitting the shed even though that's closer to it because it is targeting the hoop. I mean, come on, the Red Alert TC didn't just hit random ground objects, it only struck non-Soviet grounded objects (and people).

I guarantee you on some random geekblogosphere site's comments: "wow how do u get that thing 2 target stuff?!"

And then the essential Youtube comment that we've all gotten on TC-related videos: "OMG how u do that?

I haven't been very clear I guess. This is not a 19 foot spark. It is a 3 foot spark which is pulled out on a wire over 15 seconds over that distance towards the basketball hoop. The cameras long exposure over 20 seconds makes this look (sort of) like a very long spark. That is entirely the effect I want to give to simulate the Red Alert TC which was able to target things with "microwave beam ionisation guidance".
Now that I can do that I will proceed to the other modelling aspects and the next problem which is trying to tune a sphere and 3 toroids plus a 25 foot wire. I am using 13 of 17 turns to tune a small toroid with say a 6 foot wire. I may have to make temporary primary turns as I would prefer this to making another cap bank to add on.

Here is the topload as per Red Alert. The upper part is my 4 inch secondary which died recently with internal flames and smoke. Looks perfect on the outside though. It happened that it was a simple fit to the top of my big TC and also to the sphere and allowed room for a spool. Nearly 12 foot high without adding to the base so has to be disassembled before going back into the carport.
The photo below is just a bit of fun using multiple gaps in the wire. A Tesla "plasma cannon" if you wish.
A 10 second exposure with no wire movement.
