I do know what I'm talking about and I didn't flame you. If you feel insulted by expressed opinion, that's on you bud. I don't see any 9v going though any piece of metal holding a "handful" of nails though. People have already made it clear that they want to see the prototypes, not just see a paint picture.
Now, if you aren't going to be helpfull, then don't bother posting here.
HAAAAAAAAAAAA
I just gave you the plans for a fully operational, easy to assemble, inexpensive and stable (as in without 900 moving parts that have to move perfectly synchronized) minigun. Not to mention, I'm trying to save you from hours and hours of agonizing work on something that, even if made functional, the mass of moving parts are destined to misalign with the slightest wiggle.
On a more productive note, if you wish to continue with this idea, I have a way to make your shell eject work. You didn't outline any plan for doing it so I'm not sure if you have one or not. In order to disconnect your shell holding electromagnets, add a NC lever switch (also known as Snap action switches with levers) onto each circuit (I'm not quite sure why your diagram has 4 circuits in the first place, but I guess if you want to do it that way.. In all honesty I don't think you need the magnets at all, since gravity will hold your shells in and make them fall out). Put a bump on the shell right over the shell eject spot that actuates the lever switch. This will turn off your electromagnet for a moment, and gravity will drop the shell in at the same speed as if it was a bowling ball.
A couple more things: In the key on your diagram, red is electrified areas, but the only red in either picture is the plunger head.. And when the gun is firing in the diagram, there is no shell in the firing barrel.
How do you plan to make an airtight seal between the plunger head and the shell. The shell fell in through the hole in the barrel and falls out through it two steps later, so it will be there for the firing step. Perhaps a spring loaded curved door on a hinge right above the firing barrel spot (attached to the shell also of course)?
Don't get me wrong, I do love the idea of a nerf gattling gun.

You obviously know what you're doing with the gears; I'm just helping point out and fill in the gaps. It's what I'm good at. Big, complex situational problems.
Does anyone else think what I'm saying makes no sense? These are, in fact, things that will have to be taken into consideration at some point if we're going to follow through with this.
Maybe while we're at it we should add an assembly line thing to the shell eject that refills them with darts and carries them along tracks back up to the shell loader! Like a gumball machine on 'roids!
Hehe.. I just noticed I posted at 1:23 server time..
Teehee.
