Weapon construction - portable plasma balls?
Hello all!

Well Sif went well (despite a few wardrobe malfunctions involving velcro and tights!), and I'm already excited for next year.

Here's my question: I want to make a Tesla cannon by customising a Nerf gun. However, as you can see...

... it's huge, and when in standby has a small bulb of plasma/lightening in it's centre.

The rest of the gun should be okay, just customising a suitable NERF gun or similar but how on earth should I do that bulb?!

The only similar thing I've found that's portable enough is a belt clip on eBay, but it's a large round disc and wouldn't be mountable in a long gun.

'There is only do or do not. There is no try.'

depending on the size of the panel needed, if you're really after the glowing plasma animation, then i'd say your best bet would be a phone / tablet slid in there, with the animation on a constant loop on the display...

Phone battery should last a day or so with data, wifi and bluetooth turned off... so that could work...

just have to carefully mount the phone inside the gun housing so you could still use the touch display to start the animation, and then turn the timeout on the screen off.

If you get a clear piece of plastic and coat it with black ink, then "etch" lightning into it you can use that with alternatining flashing green LEDs behind it.

It'll be the same lightning pattern, but the LEDs behind it should flash randomly enough to make it look like random plasma lightning.

I know it's not the best, however getting geniune plasma plates in there will be tough as they're usually round or you can buy square ones in wholesale (min 1000 units)

If you're insanely stuck, go to Cyberdog in Camden if you're in London or check out their website. I'm not 100% sure but that's just the kinda thing they might put on a T shirt or accessories. A quick shufty on their website and you get this http://shop.cyberdog.net/light-ss-electric-storm-sound-reactive/p564 If you're a huge fan of Cyberdog, it's a pretty sweet alternative.

You could also thread EL wire through in strands, black out sections of it and have them flash alternatively
