30 bps redux

[314159]

*edit* (to be nice)

with the last sound clip, there were a couple concerns expressed:
-the rate of fire was not sustainable
-the marker was not in perfect working order
-the marker had to be "recocked" (actually the hammer was in the cocked position and was reseated on the sear after every string)
-there was no controll over the marker cycling (the sear was not catching the bolt everytime)

yay, the files:

this should show that we have controll of the marker

this soundclip shows a long string. yes, the tank does go empty at the end. the marker is obviously starved for gas at the end of the string (tank empty), and this can be compared to the rest of the string (when the gun is not starved, not half firring, and under controll)

didnt even listen to it but il guesse its a spyder...


Edit: just listend and that sounds messed up

the second clip sounds like you're getting some heavy shoot-down or your tank is running dry... the dry-fire makes it sound really wierd too.

what is it?

the upper half is an old dragun black (not the newer electro black dragun). and it has black dragun frame on it, gutted, with some special electronics controlling the solenoid.

the second clip was shot with a tank that was almost empty to show the sound of the marker when it is starved of gas (tank empty) and let it be comared to the marker cycling at 30 bps with plenty of gas.

cool....

Next up...video! Good job!

Have you thought about increasing the sear "lock" time and seeing how fast you can go while shooting paintballs? I haven't been able to view the video yet, but it would seem that the only thing you need to do to get it to actually shoot paintballs is have the sear hold the bolt back long enough to load a paintball.

[314159]

based on a measurement of 20 ms for one cycle. at 30 cycles a second, that should leave 13.3 milliseconds to load a ball.

i guess we will see if that is dooable with a force feed =]

That seems like a very small amount of time to load a ball. I'd personally suggest increasing the "sear latch" time and using something like a 12 volt warp or Halo B. Good luck.

this is going to be my last post on this before shatnerball. (the powers that be want me to have something to suprise people, i can't give it all away before the big event)

let's just say i am intrested in how little time i can get a ball in the chamber .

and for one specific unbeliever out there, and to ever else that it might please.

good work guys... maybe this will lead the way to very inexspensive high ROF guns that normal people can afford...

[rhetor22]

pretty much all blowbacks are capable of a very high rate of fire... but they will suffer blowback, and inconsistancy.

The internals of spyders and their clones can go pretty fast. Its nothing new.

The only thing holding them back is recharging rate and paintball feed rate.

but a full auto blowback is incredibly simple. in fact its simpler than a semi automatic blowback. the only problem is that its too fast.

You know.. I may actually listen to these at some point... but not now.. sorry. What I WOULD like to say though is that it seems you DO miss a lot.

Please stop calling me an "unbeliever".

What I said, and will state again, is that I was not arguing IF your marker did what you said it did, but instead the fact that NONE of the information you provided last time proved it. I never said I did not "believe" you. I would very much like to believe you. In my heart I believe you. But what you showed and posted was far from being proof. You may have corrected this with these new clips, or again you may not have.... we will see later.

I hope that better explains my position on this matter. Have fun.

(Note: I also have to add so that people don't get the wrong impression... I am not upset.)

Sam, my suuggestion is to just go with what he says. It is true. I have talked to him on more than one account and he knows what he is doing.

The E-mag demo was NOT done with a 3000 psi input either

You might wanna correct that bit of misinformation...

The scuba was nearly empty at 900 psi for the reason that you will be hard pressed to find a tank reg that will recharge the RT valve set at 300 fps.

All the tanks we had instantly dropped 400 psi as soon as the trigger was depressed.

If you are not experiencing a similar pressure drop from your tank that means you might be shooting low.

It would be intresting to find out how fast and consistently (velocity wise) the e-mag is shooting compared to the 30 bps spyder.
