potential hall sensor cheat?

[brianlojeck]

I posted this here because I don't feel right posting it to the tech forum...

NOTE:

1: I have no intention of doing this
2: You should not do this
3: this is a question I have for research purposes only
4: no, I won't tell you how to do this

Lets say I wear gloves, and in my gun hand glove I have a small piece of iron. in my sleeve is hidden a battery pack of some sort, and a small circuit board who's only job is to pulse the DC on/off at a set speed.

basically it's an electromagnet that turns itself on/off.

am I nuts to think this might work? a bone stock emag could be made fully automatic VERY cheaply if I'm right...

[eNder159]

just to clarify are you thinking of making an electromagnetic field out of your hand?

[RRfireblade]

He's talking about making a controllable electromagnet inserted in the finger of a glove.

Sure, it would probably work but would be difficult to have function effectively. The window of space available to 'trigger' the HES is very tiny. You'd have a tough time keeping your finger in the exact perfect location to trip it reliably....especially while running around.

Also, to get passed the chrono judge you'd have to have a functioning trigger in place and a way to get around that in order to 'cheat' later.

"Cheater" software is a MUCH better way if cheating is the ultimate goal and why it's the most common method used to date.

not thinking about DOING it, I don't own an emag, and have no need to cheat. just sleepy and thinking crazy thoughts at work...

-and-

not OUT OF my hand, but of hiding a pulsing electromagnet in my glove.

I figure the field would collapse every time the current died, which may well trick the hall effect sensor into thinking a magnet just passed by it.

Yes.

I figure a powerful enough magnet would make a large enough field that the placement would not be so critical...

precisely what I'm talking about. if the gun is stock, and I have a cheater glove, then the ref can't make the gun "cheat".

but that requires changing the gun itself, and can be detected.

like I said, I'm not planning on doing this, just muddling in my head...

[RRfireblade]

Not saying your ARE trying to do it, just responding to the thought.

My points still stand however.

Your not going to able to create a large enough field of activation with something small enough to not be noticable in the finger of a glove.

and....

You have to have a functioning trigger in place.....as in.....in the place your finger would have to be for it work.

and....

Cheater software is far more reliable in function,extremly hard or impossible to detect if done correctly and much less apt to be found out than and electromagnet in the finger of your glove and wire running from it to a battery in your pocket. (or whereever). :) Not to mention if your worth your salt as a Paintball player your going to need one in each hand so you can switch shooting hands during the game.

Is all I'm saying. This is not a new concept,not with HES sensors or optical sensors. The idea to trigger a marker with simply a finger or glove has been well a discussed topic.

Magnetic fields do not instantly dissipate, which is a reason why we have degaussers. How fast it dissipates depends on the metal used, and other factors. (Although, all this might be completely moot for what you're proposing).

Has someone previously thought of this? Yes. I did - and I am no where near the first.

There's better ways...

Pretty much any electronic marker can be made to shoot FA cheaply - couple bucks or so.

I also thought of this a couple years ago and using a digital AC pulse . A 555 timer should do the trick with ba small coil of wire and a switch on another finger to activate it. all available at Radio Shack. I used this same circuit to make a stepper motor vibrate for a crude laser scanner.

Interesting, me too! Which would lead me to believe that many people have thought of this.

[Lurker27]

You guys are makig this way too complicated. The 555 thing would produce a recognizable audio signature, and would interefere with the motion of your fingers, (remember an astable 555 must haev duty cycle of over 50%)

Just connect the NC and NO leads on the switch with an HES. Works like a charm. Split off +9v and drop down to 5 or so with a 680ohm resistor. (better safe than sorry)

[brianlojeck]

I think you guys just hit the limit of my terminology knowledge in electronics.

an HES? A High Explosive Sabot round? ;-)
------------------------------

also, (going backwards here) while a magnetic field may not collapse immediatly, the field around a coil does collapse quickly enough for a car's coil to cycle several thousand times/minute. I figure 30bps can't be THAT fast electronically.

also, with the idea that modifying the gun would be a "better" way to do it, that may be true, but then the gun would be modified. I'm talking about cheating with a bone-stock gun that's had no modifications to it, that absolutly cannot be detected by any NPPL gun-firing "robot".

at any rate, thanks for the input guys...

[PatrickLee]

Well what if you had a completely steel trigger, and connected the wires to metal pads on the glove, therefore when you touched the trigger, the steel trigger would act as a big magnet?

I'm not to savvy into electronics so i don't know if it will work.

[Lurker27]

what's the upside? the pads of metal would have tpo be exposed, making your cheat less furtive than obvious, whereas a magnet is quite easily concealed.
