Magnetic "Response" Trigger

[dyst0pia]

Yeah...so...I am somewhat nervous about posting this...worried that everyone will just flame me and tell me it is the stupidest idea ever...oh well, here goes nothing:


I am curious as to whether it would be possible to place a magnet both behind the trigger as well as on the frame (aligned with the one on the trigger), as to create a "response" trigger of sorts.

Basically, my idea entails having these two magnets with the one on the frame being electromagnetic so that with every pull of the trigger, it switches polarity.

What I would like to achieve with it would be a trigger that when you are pulling, the magnet assists you by force of attraction. But, after you have fired the shot the magnet on the frame reverses polarity so the trigger is pushed away from the frame. I am not too sure as to what would be necessary to make a magnet switch polarity, but if this would be possible, I think it would be somewhat interesting to try out.

Obviously, it would not be tournament legal.

Also, I think it would be possible to adjust magnet size to allow for personal preference, as well as lighter force magnets for those of us using a ULT on/off.

Does my explanation make sense at all?

If not, tell me, and I can try to describe it in a more precise manner.

Is my idea really so bad that nobody has a response to it?

[paintballman_13]

i think...

i think its the worst idea ever and everyone should flame you.

lol j/k i think its a good idea. i would like to see it work.

What I would do is have the electro magnet running at a lower charge than is needed to provide enough force for the trigger pull. The nwhen the gun is fired, whatever board you put in this contraption pumps alot more power into the magnet. This way all you would need was the trigger magnet and the electro-magnet

The only downside would be how the gun would slowly drian your batteries to provide resistance for the trigger.

Wait...it sounds to me like you mis-understood my explanation. I originally only had the 2 magnets in it, one of them being electro, the other being just regular. My concerns were over how it is possible to change polarity of a magnet, and how it would be triggered.

But, if I am understanding your comments correctly, you seem to be saying to just only turn the magnet up in power when you have pulled the trigger, so it only repels the trigger. This would be instead of it switching polarities? Interesting, but one of my goals was being able to have an assisted pull AND release of the trigger.

However, I might just be totally misunderstanding you. Is this the case?

I would say to have the magnet on the trigger a standard magnet.
Use the electromagnet on the frame. Same as you said, however, I agree that it should only assist in pushing away.

If the electromagnet is not "charged" when pulling, the magnet would automatically be drawn to it since it would in essence be a chunk of "attractive" metal. Then turn the electromagnet on when the trigger had been pulled fully. So that it would push the trigger back to the forward position. Just have the electromagnet turn on with the solenoid.

I spent some time thinking about this and the idea is ok but correct in that it wouldn't be legal.but onto how it would work.

Ignoring the switch of whatever type to make the marker cylce for the moment you could not as suggested above have only the one magnet as the forces by pole switching would stop the trigger from working. So you would need to begin with a magnet at the top and one behind the trigger in the frame...the pole shifting would work but only if when contact was made the magnet then reversed polarity, so you would have one switch per magnet but due to switch changing the polarity of a magnet when it (the trigger has made contact) you would have two switches in addition to the cycling switch. As one of the magnets would already be switching polarity as you switch the marker on the only way to ensure that the trigger cycle would not complete would mean hold the trigger in what would be the firing postion in a traditional marker..and as soon as you removed your finger then the trigger would reset and then the top magnet would reverse polarity so you wouldn't actually need to touch the trigger unless you wanted to reload..as soon as you remove your finger it would become a self firing marker, so unsafe it is untrue. Only using one magnet would be counter productive as the very close proximaty to the frame this magnet would have to be extremely small to counter act the pull a magnet has and short triggers would mean that effectively the marker would only fire the once and stick in the fire or off position. I hope this makes some sense I was even thinking on how I could draw a very much exploded diargram to explain how I think this would work. I sure as hell know how to draw it in pencil but on a pc it is a just a little harder

[dyst0pia]

I had a feeling that would be the problem. Once you got the thing started, you wouldn't be able to stop it. I guess my original idea used the idea there had to be additional force besides the magnets to cycle (ie, your finger), but when I think about it, there is a high likelihood of it going runaway.

I don't believe that you can make magnets instantly switch polarity. Scientist claim that the earth does this about every 70-100 million years. (I'd love to see 'em back that one up)

I would try to instead come up with an assisted pull via electro magnet, and once the trigger was all the way back, turn the magnet off and let a reactive valve push back.

[Mag_SEAL-6]

It is entirely possible to switch the polarity of magnets using electricity. It's used all of the time (ex: roller coasters).

sorry to go offtopic. but they have. its' called paleomagnetism. i know of 2 cases. first is in digs. scientits noticed that as they went futher down, the poles switched, then again. etc.

the other is in the oceans at the rifts. as more molten lava is brought up, it cools, pushes rock outta the way and keeps the same polarity as it originally had over long periods of time. so near the rift it would be one way. then they noticed that at incremental distances away from the rift zone that the polarity changed. on both sides at the same time. http://wwwneic.cr.usgs.gov/neis/plat...nics/rift.html this site explains it better. i can't find good pics online right now.

now on topic. yes it can be done, i'm sure i can rig up a button switch with ac current that does this and all you have to do is either let go or press the button again to stop the trigger/magnets. but all this does is bring new meaning to the frase of spray and pray tactics. also this is pretty much full auto.

Electro magnets

Yes it is very possible for you to switch the polarity in an electro magnet. this is because an electro magnet isn't really a "magnet" in the sence that most people think. all an electro magnet is, is a coil of wire that has an electric current passed through it, with no electricity you have no magnetinc force. This is do to electric fields producing magnetic feilds. All you have to do to switch the polarity is switch the direction of current running through the coil.

Electromagnetic Response

It's an interesting idea, and one that could have merit. I think the main issue would be finding an electro magnent that is small enough to be useful, while still having the power to repel a magnent attached to the trigger.

Another possible issue would be having magnents in close proximity to the electronics. I don't know what effect this would have, if any(it's likely that you could probably pull it off, seeing as how the emag manages just fine).

Third issue would be the amount of power it would take to be effective. Can you make or find a system that can handle and switch the voltage/current needed to power that magnent?

Fourth, HOW would you control when it switches? Would you like to slave it to the solenoid as was previously mentioned, or would you like to do something gutsy by buying a morlock board, and running the electro mag off the second solenoid leads? The morlock option would give you control over the pulse time, when it was pulsing, etc. It might be something you want to look into.

Like I said, I think it's a good idea, and it looks like it might be able to work. There's just to much uncertainty about the overall output the magnent will be able to give you in my mind.

emag

E-mags do have a problem with it you can move the magnet too close to the grip, then the electronics stop working till you move it farther out, at least my X-mag does

[tjmpaintball06]

Its along the same lines of the mag-lev train. A series of electromagnets on the track and the train itself. The ones in front of the train attract it and then switch polarity when it passes to repel it. Thats what propels the train down the track. It would work in the trigger but it would need adjustment.
