    Marker Gas Supply Possibility...

    OK, this started as a joke over on the MCB, but before I finished making what was going to be a sarcastic remark this interesting possibility wandered into my head and I'm not sure but I think I just might be on to something...

    steam engine turns compressor pump...
    compressor pump fills HPA bottle...
    HPA bottle is connected to marker as usual...

    my god man; you have revolutionized the back pack idea!

    just got to use an electric element to heat the water and fill
    your "Batman" utility belt with capacitors/batteries to run the whole rig...


    you know the sad part...
    that is just crazy enough that it might work...
    only electric motor turns compressor pump in back pack filling HPA bottle/tank
    which in turn is connected to the marker by remoteline...

    kind of like that gun NPS came up with only move the compressor off the gun into a back pack with an HPA bottle to work as a bulk reserve, say 13ci should be good enough...
    even if it needed 3 or 4 of those big 6V or 9V lantern batteries, in a back pack
    that is more or less reasonable...
    hhhmmmmm.........
    gotta talk to a buddy of mine that is into Marine Robotics...
    i just might be on to something here; good lord this post started as a joke, now i just might have a great idea...

    oh crap...
    not even finished the post and the Gardeners patent ambushed me!
    now here is the real Idea and Mr.Kaye if you could please offer your insights it would be appreciated, OK here we go:
    you take the compact compressor like the one used in the NPS marker
    have it fill a 13ci HPA bottle to say 1500PSI enough to keep the hungry markers chugging along but small enough to keep the pump run time short.
    this goes into a pack pack with a rechargeable battery/capacitors to power the pump and the electronics needed to turn the pump on/off when the pressure drops below a preset level.

    the big problem with the NPS gun was that putting everything on the gun made it very heavy
    the batteries were small so only had a short cycle time; over all the gun was only good for half a hopper of paint then needed a recharge.
    move the compressor/bottle/electric source off the gun,
    put it in a back pack where the load can be better dispersed and is easier for a person to carry and we just might have a Paintball fill rig that never need to be refilled with any gas as it will just pull air in from atmosphere.
    OK, the batteries will need to be recharged, but I'm sure that there is battery technology that i am not privy too that will work for this application.
    if you could get a 4 hour duty cycle;
    continuous operation for 4 hours similar to many gaming laptop computers,
    because the compressor will not be running 4 hours continuously because of your reserve take and the pressure switching electronics
    a person should get a full days play out of a single charge, or maybe even longer.

    Engineers of the A.O. examine this idea, offer your thoughts, suggestions, pertinent information on small/micro compressors that could do the job, switching mechanisms, battery/compressor power sources that may fit the need...

    please keep everything positive and contributory.
    this might work, it might not, but it really does seem possible.
    but this is not my area of expertise, and I don't have the $$$$ to experiment with the idea.

    seems to me you would have pretty heavy pack your back , but in the spirit of things make a receiver that would take cordless drill batteries that way you could get replacements or additional batteries at the local hardware store

    but don't you remember this gun:
    NPS EVolt
    the compressor must exist!

    This is the official press release from NPS:


    --------------------------------------------------------------------------------

    2-10-05 (Sewell, New Jersey):

    The worldwide leader in the manufacturing, marketing, and distribution of Paintball products, unveiled the first in its new line of Paintball markers, the EVolt™, which utilizes patented Power Pulse™ technology, on January 28, 2005, in Las Vegas at the SHOT Show.

    Gino Postorivo, President and CEO of National said,

    This is not simply a revamp of known Paintball technology, but it is a truly revolutionary design, with patents issuing imminently on the first generation of the EVolt™ and various patents pending on the second, third, and fourth generations of this revolutionary new technology.
    so the compressor exists,

    The EVolt™ Paintball marker is powered by a rechargeable 18 volt battery pack. The battery not only powers the cycling operation of the marker, but actually generates the compressed air required to launch the PAINTBALLS. Air tanks not included... and not needed.
    so the compressor exists, it's out there some where!!

    The entry-level, first generation EVolt™ Paintball marker is currently capable of cycling at a rate of over six PAINTBALLS-per-second with velocities up to the "industry standard" minimum of 300 feet-per-second. A fully charged battery gives over 500 shots at a consistent velocity. The battery may be recharged in approximately 90 minutes, and can be replaced in seconds. The ambidextrous "Bull-Pup" design includes a Picatinny sight rail, removable clamping feed neck, "Timmy" barrel threads, angled foregrip and lockable velocity adjustment. Accessories are currently being developed.

    Production quantities are expected in time for the Fall/Christmas 2005 selling season. MSRP is about $250

    It is not exactly a beautiful gun and it's 6 bps is pretty meager, but this is the first marker that is powered by batteries other then compressed air. It is a new design and it's in it's early stages, so the weight and appearance is understandable. Who knows, maybe this will change Paintball forever, and we will laugh at the day that we used co2 to propel PAINTBALLS. Here are some more pictures.

    so the compressor exists,

    and if you take it off the gun,
    add a bigger battery pack,
    and a storage tank for a given volume of air,
    you should be able to make a back pack version work.
    it was the restrictions of the marker body that limited performance.

    compressor = a lot of batteries = very expensive

    I'm pretty sure that the Evolt did not use a compressor. I'm almost positive it used a spring piston like design.

    I could be wrong though...

    Sorry that I don't have anything helpful to add, but I like the idea, and I seriously think that it can be done. If I had the funds and the facilities, I might take this project on...but I don't. I hope someone can get somewhere with this, though.
