I was originally planning on making a minigun but one of those is already being made so i drew up this design for an automatic belt fed machine gun. I made a short animation of it here:



A small electric motor is used to push the dart from the belt into the barrel past the small hole for the air resevoir. When the rod is back, another motor rotates and catches the next dart holder on the belt and moves that one into position. The barrel is sealed behind the dart and the air resevoir is unsealed accelerating the dart forward. Then the resevoir is sealed, the barrel unsealed, and the next dart put into the barrel which starts the process over again. The air resevoir would be filled with an air compressor.

There are three big flaws with this idea.

1) I don't know how I would go about sealing/unsealing the air resevoir and back of the barrel.
2) The timing on the motors has to be precise and while I've used servo motors controlled by a board programmed in C before, I do not have access to those and I do not know how to obtain those for cheap.
3) Whatever I missed.

I would really appreciate if someone knew a way to solve the problems with this idea. I'm going to try and make a simpler design if I can't think of anything to fix these problems.

Edit: Here is an idea for the sealing/unsealing of the barrel and air resevoir.

First I would like to say that I'm sorry I can't post a picture yet because my camera broke and it hasn't returned from the shop yet.

I have one question. Is 50' flat a good range? I haven't tried it at an angle.

I did the basic mods for it such as an improved spring, knocking out the air restrictor, put glue and electical tape around the parts of the barrel that needed a better seal. I also put teflon tape around the plunger.

Then I cut out the "laser" LED housing and the dart holders. I glued cardboard onto the holes and covered that with electical tape. Then I took the piece that housed the lens of the "laser" and glued that to the bottom of the front. I took the 4 pieces of the dart holder and glued them in a line. Then I glued one end of that to the lens housing and put supports around it so it was not flimsy. The dart holder holds 8 darts. I can unscrew the lens housing to take off the dart holder. This is probably a bad explanation but I will take a picture when I have my camera back.

I also lengthened the barrel with 1/2" CPVC
