Maybe it was an efficiency improvement or greater power output or something similar

i heard they were going after the guy that made the shake weight next. lol

Wouldn't work very well at all, that's probably why it hasn't been done. When generating power the magnets would drag slowing the bolt down.

So what you're saying...is that the marker would have the efficiency of a Geo

Unless the bolt was the magnet?!?! think about it! i think we got something here. they could also do it with excess air like a windmill.

[y0da900]

Excess air = inefficiency. Even using the air normally vented to cycle would create a restriction in venting and slow things down.

Take a small motor and spin the shaft by hand. Now hook a lightbulb to the wires and try to do it again.

the whole point of this project is to make the g series better not worse.

lol thats funny but it is also very true.

:o Us vs apple.. we win, any day. XD

A magnet and a coil will pass each other with no resistance as long as there is no load on the coil. Put some sort of load on the coil and the magnet passes the coil with increased resistance. What you are asking for is a way to charge the battery off the "excess" energy in the bolt. The problem is that there is little or no excess energy. An efficient gun is efficient because it doesn't waste energy or put extra energy into moving the bolt that isn't needed. You are wanting there to be waste energy that you can take advantage of so that you can use the bolt movement like a magneto...not going to happen.

The QI option is more likely. However the receiver coils all deliver 5 volts so they are not capable of charging a 9 volt battery.

Could 5v be enough to for solenoid to operate?

why are we still talking about this?

Nobody said you had to reply. just talking for sake of talking of outside tech that could be used in pb.

Think he meant would prolly be a good idea it had it's own thread. This is for the guys making the new bolt

not consistently. deff not enough to run a paintball marker reliably through a tournament.

NO

[Deathwish_DW]

Don't hate on random ideas.
How do you think Jonathan and I got started?
=p

Anyway, contacted another machinist off of MCB.
He's reviewing the prints and will hopefully get back to us soon.

5v could power the solenoid, but gun boards are designed around 9v. There's a very simple circuit called a joule thief that can take a lower voltage and step it up to whatever was needed. It uses a tiny transformer, and a couple other very small parts all of which could fit inside your gun frame. I have considered using a cell phone battery which are lithium ion and a joule thief circuit to power my gun. It would be fully rechargeable and smaller than a 9v battery. Adding an inductive charger to it would make it totally enclosed with no external connector to charge the battery. Cell phone batteries can be purchased for a couple of dollars for older phones. I might have to revisit this idea with the inductive charger. A Lion cell battery with a 9v connector, inductively charged that was an exact fit replacement for a 9v battery is compelling.

It would be possible to have a fully regenerative gun that used air as its power source. You would always need a battery so that you had a starting point, but as long as the gun was firing, it could generate electrical power that would charge the battery. I suppose a tiny impeller could be added to wherever vented air comes out that drove a tiny magneto to generate electricity. You wouldn't impede air flow and may get what you need to charge the battery. Something integrated into the air flow path going into the dump chamber would possibly work best. Very small flat neo magnets glued inside the bolt may not add significant weight to make the bolt too heavy to fire reliably and then a pickup coil on the side of the gun body to gather the magnetic pulse might work as well. In the G4 with the Techt bolt a magnet could be added to the inside of the bolt tail and a coil carefully wound at the back of the stop block that would pick up the magnetic pulse. The wires could be ran out the back cap and sealed with epoxy around the hole. Of course with the bolt described in this thread, I don't know how it would be possible to accomplish this idea without having one in my hands to play with. I guess you could say, I'm somewhat recanting on what I said earlier. I think with a couple ms of dwell added, this would work. You would lose some efficiency. An impeller added into the air flow path into the dump chamber would not impact dwell and for most of us that have no need for 30bps firing rates, probably wouldn't impact air flow sufficiently to cause shoot down.

I love joule thiefs!! I powered 3 led's off of a dead AAA using a joule thief the only issue with it was it takes up quite a bit of space. That means it would be hard to fit it in the grip frame but you never know someone will get it done if it really makes a difference.

Depends on how you wind the transformer. It is wound on a toroid and they can be very small. In this case I think one that is 1/8" thick and around 3/8" in diameter will do the trick. If I use 30 gauge transformer wire or smaller gauge, it will be small enough.

[stuff21397]

That's true I did use thick copper on a pretty large piece of ferrite

[firefoxx04]

okay come on guys, we have a customs forum for this. great idea but it does not belong here.

Move along please!
