a marker that doesnt use gas?

[John Molloy]

I wasn't aware of any "rail guns" currently fitted to any warships, anyway Gauss is the same principle only man carried (side arm) and the batteries are the problem for any system. They use super conducters to carry the charge that holds the object in suspension.
Their is a train in Japan based on this technology ( and I think it has started a migration to other areas) the system is called Mag Lev (magnetic levitation) once going it doesnt take that much power (less friction to push against).
If your system is along these lines with tech at the current level to reach 300 fps how long would your barrel be? the system will work but you may find it easier to tap the opposite back player on the shoulder with your barrel and any static charge you apply to the paint would risk affecting you as well (I can see your hair standing up like a toilet brush LOL) Think on the design any way cos battery size is coming down and you may find you can get a Phd out of it (original research cool )

Hmmmm, dont wanna piss on anyone's fire but...... here's the deal, firstly, it is impossible (as somebody has already mentioned) to propel a paintball magnetically, secondly, you can forget a static charge propulsion unit, I'm afraid there is no way you can induce suffcient charge in a paintball and you cannot provide a propulsion system that can propel a paintball at 300 fps even if you could charge up a paintball (well not that was portable anyway)

You gotta remember, the guy who is proposing this, is a young kid and whilst he should be commended for his imagination, I am afraid the harsh realities of physics will bring him back down to earth with a Newtonian bump.
I think from what he has said, that he is thinking along the lines of powering the control side of the gun electronically (which as we know, is not that much of a problem) but to also propel the paintball with the use of such things as solenoids or whatever, and remember not just one but thousands if this gun is to be deemed practical.
On that basis, with current technology as it stands, he would need a battery the size of Big Ben stuffed up the grip frame.

OK, here endeth the physics lesson and I guess here beginneth the onslaught of abuse.................

im getting everyone mixed up with analogies of bullet trains and railguns.

its basically an electro magnet based thing...someone said that part of it roughly resembeled the kind of solenoids used to lock car doors.

dont wanna say too much, for patent reasons. has anyone ever heard of anything similar baing developed in the paintball industry?

the gun itself is very short...as i said, it will proabably be shorter than most markers (without barels ) today.

please stop guessing what im doing but thanks for the advice

I'll show you all!!!

dont think in strait lines...i know that the static charge wont work.
i know that you cant propel a paintball using magnets.

i didnt say i would do either

yes, batteries is possibly an issue (hence the prototype). sorry i can only give a half picture here. and am getting some people muddled up.

As I said Sttab, I didn’t want to piss on anybody's fire but I also wouldn't want you to waste your time.
Just so you continue your experimentation down the right lines, here's what you have to do so you ensure you are not wasting your valuable time.
Work out the weight of the average paintball.
Work out the energy required to propel that paintball to 300 fps and then to multiply that figure by at least 15000.
This would basically cover a day's play before the need of a recharge.
Secondly, work out the energy requirements of the logic and control units for at least 8 continuous hours; this gives you, once again, the worst case scenario for a day's energy requirements (for the control electronics).

Once you have added those two figures together, you then need to design a system that will allow sufficient surges of current to propel a paintball to 300 fps using the solenoid type system of propulsion and believe me you will suck some amps with that little baby.
Once that little lot has been done, you then need to design a wheelbarrow and harness to put the power source (battery) in so that at least it has some mobility rather than running round the field with a 300 foot extension cable with the other end plugged into the Drax B PowerStation.

But on a serious note, if you do the first part of what I advised and then look up the figures with regard to battery technology, then you will make damn sure you can make the right choice in what to do with your spare time coz u will be wasting it if you ignore the basic principle of energy resource technology as against total energy requirements for the gun.
Good luck young man !!!

everything youve said has already been taken into consideration.

onn my design for the semi version i have a rather elaborate system of capacitors. no doubt she'll be a heavy bitch.

ive talked to some people (physics teachers and technichal teachers) who have no doubt my design will work and accelerate a painball at 300fps, but are not sure about power usage (in my design they resembled a gun clip that would be inseted into the grip frame, that could be quickly changed) guys who have remote cameras for long usages (like at rugby pitches) have a battery belt.

im not really considering this as a real option (it probably causes cancer or someting) but the dude who kind of designed the mains electricity systems in most peoples houses always wanted houses to be powered by a giant remote thing (i cant remember the details) that would be at the centre of every town, that would generate a electrical field that could be used by houses. (he also invented those hallogen bulbs i think and powered all his lab equipment in the above way)...this is bordering on fantasy, but you could have one at the centre of your field to power all the markers, making them supremely light.

 

[Cook$]

try petrol. Imagine, a two stroke marker. hmmmmmmmmm........

 

[John Molloy]

Thus making 'em supremely heavy, loud and smelly (just like walker lol, that was a joke by the way).

 

[John Molloy]

try Ethanol instead if worst comes to worst and you are eliminated get p1ssed in the dead zone lol

Hey Sttab, if you are thinking of using caps then you need to get a new physics teacher because he should have told that you need to re-charge capacitors after every discharge.
Combinations of capacitors, however elaborate, cannot get past the working limitations of the charge / discharge characteristics.

And the recharge time has to be something less than a tenth of a second for the final cap that drives the solenoid.
Bearing in mind the current requirement for that capacitor (to propel the ball at 300 fps) I have no knowledge of any capacitor available on the market that would allow you to stuff it in the gun.
I think your physics teachers may well be getting a little confused with the idea of propelling 'a' paintball (which is possible) as against thousands of them, one after another.

The primary capacitor network required to feed the final feed cap would have to be as big as a medium sized Cadillac (Estate version) .

In terms of power resource energy, I'm afraid Mr Boyle wins the day every time over Mr Faraday

Good Luck Mr Sttab !!!
