Need Special Effects for Office Party

My office has decided to have a Halloween office party theme of Rome this year. I quipped about coming as "The Electric Gladiator." I was taken by surprise at how strongly my comment grabbed everyone's imagination. So, now I need to figure out a way to make a respectable presentation as an electrified Roman gladiator.

I am asking for help getting it put together. Keep in mind that I work in a computer center. Although everyone in the office denies this is a concern, I don't believe that a lot of open sparks are a good idea in the office. So, I am leaning more towards using lights (light bulbs, black lights, LEDs, EL displays, whatever I can find), with very limited (if any) use of electrostatics. Even so, if I could deliver a strong spark to my office manager, I will count it as a win for the day (he probably would, too). He is coming armed with a pair of spike-studded balls on chains, and he intends to challenge gladiators (especially me) to combat.

Two other limiting factors: I don't want to spend very much money and I don't want to do a lot of construction. I would prefer not to spend anything, but I might be able to justify spending $50 for a really good idea (especially if I win the costume contest of $100). Several years ago, I built a high voltage power supply that operated off a 6 Volt battery, but I had to return the main component to the man who loaned it to me; I am able to design and build simple high voltage power supplies. I am simply trying to avoid doing so.

Maybe something operating off a 9V battery? Does anyone know of a solid-state converter that will convert 9 Volt DC to (say) 3kV A.C.? I was thinking of maybe using a Class C amplifier to get the brief voltage spike I want.

I would appreciate your assistance on this project.

Thank you.

Buy a cheap stun gun and try to tone it down a little? :-) -->

Technology and special effects are cool...especially in the eyes of the one building the toy. BUT My experience with parties suggests that $50 spent on booze will do more for the "spirit" of the party than any special effects you can build. ;-)

On a darker note, anything that "shocks" a person is a BAD idea. Putting the boss' brother into cardiac arrest is not a good thing. Call up your insurance company and see if they cover the wrongful death lawsuit. Think of it as a divide by zero. It's not likely to happen, but the result gets VERY BIG if it does. You don't shock people for the same reason you put divide by zero checks in your code. mike

That might work, but I probably would have to cannibalize it. Some places consider stun guns and tazers as weapons, and prohibit them. We are prohibited from bringing anything that is a weapon to the office, even as a prop for a costume. We cannot bring real machetes, axes, swords, etc.

Did you ever scuff your feet across a carpet and then shock someone? Do we put kids in jail for doing that?

Did you know that if you hit someone in the chest at just the right time, you could easily kill them? The blow does not have to be very hard, and the person could have been in good health. I read about a basketball player that died simply by being hit in the chest by a thrown basketball during practice, which just happened to hit his chest at a vulnerable moment. So, do we ban all physical contact and all sports?

A very brief, very low current shock is not going to kill someone. It has never happened in all of recorded history.

I don't agree with the last statement, particularly since your description of how you thought you might do it shows you know nothing of the subject, but leaving aside the probably manageable risks of shock, I assume from your description of the workplace that you are either a data centre or the data/computing centre for your business. A risk analysis of the damage that might be done does not stop at the possibility of a blown $50 hard drive - it looks at the consequential damage; customers turning away, suing for lost data, etc. If you're an outsourcing centre and I used you and found out you were screwing about like this around my data or computer services, I'd be moving my business. If you only serve your own company and I found out you were doing it, I'd take it up to CTO/CEO level. Your boss should be saying "No!" to this to if he has a clue. Don't do it.

Cheers.

Not really relevant, but when I was a student apprentice at English Electric-LEO-Marconi Computers Ltd, Kidsgrove, in the 1960s, I and a friend decided to build a sex detection machine for one of our frequent parties at the company hostel where we lived. The person being tested had to stand with his/her legs apart with their feet on a pair of Al plates. When a button was pressed the machine sprang into life - relays clicked, a uniselector rotated and lights flashed for about 30 seconds, then one of two lamps labelled MALE or FEMALE came on. It was about 98% accurate over the 100 or so people who were tested.

Can anyone guess how it worked?

Wasn't that baseball, hardball? The ball is much harder, goes much faster, and is much smaller, to induce a higher pressure when it hits, than a basketball could ever create when it hits.

If those are real maces, back out. If they're styrofoam balls with plastic pins, painted black, then just a lucite sword stuck on a flashlight, maybe a multi-color flashlight. It'd look like a "lightsaber", but Gladiatized, so to speak. :-)

Do NOT use a fluorescent tube as a lightsaber! Or for anything else, except to install in a fluorescent fixture, for that matter.

The only other thing that springs to mind is flashing LEDs all over, and by nowadays, they've probably already got something like that at the costume store.

If you want a Jacob's Ladder on your hat, (where the Romans wore that whisk-broom thingie - and so did Marvin, I think...) just look up "Jacob's Ladder" on google, and adapt one of those designs. :-)

Good Luck! Rich

But the PHB can bring a _mace_? Let alone, _two of them_???? - Oh! I erred! Sometimes people use the term "mace" erroneously while referring to something more apppropriately called the "flail":

Of course not. But those people put themselves at risk voluntarily, of their own free will. Sneaking up to someone and tasing them is quite a different thing.

Now, if the guy had called for a "no holds barred, bring your bazooka" kind of knock-down-drag-out, then if I couldn't bring an actual pistol, it'd be taser city all the way. Expecially[sic] if he's got a flail! (which I thought was called a "mace" - silly me!)

Thanks, Rich

That sounds like the Carl & Jerry story "The Girl Detector" from the early '60s where they used thermistors in a bridge circuit to look for a skirt. Girls had bare legs, and boys didn't. Its on the web at:

Michael has got it right; we used a light source and photocell rather than detecting heat. It got the sex wrong for two people, a male wearing light-coloured trousers and a girl wearing a long black dress.
