Okay, my first post here on Nerf Haven.


I've looked around online and I've seen two different types of nerf claymore/landmines. They either required a flywheel system or were spring powered and required a trip wire. I've created one that is less advanced (and quieter) than a flywheel, yet more advanced than some obvious trip wire.

Here's what I used to build it:

Pieces used to make it work:
Stomp Rocket Air Bladder
1 Inch PVC (Barrel)
JB Weld
Hot Glue

Pieces used for extra features:
Green Light
Suction Cup Dart Head
Green foam for protection

I ran into a Stomp Rocket air bladder at a friend's house last weekend and turned it into a little "landmine". It is pretty simple, load a dart into the chamber and hit the yellow bladder. I prefer to steady it with one hand and whack the yellow air bladder with the other. It can be used indoors and outdoors. It works best, however, on the floor/ground because of the angled barrel.

The angled PVC barrel ensures that darts hit around the thigh area on an adult. If the barrel were flat, darts would be hitting ankles. The side of the pipe that connects back to the barrel was shaved down by my dremel unevenly. This makes for an angled barrel because only one half of that side is in contact wit the bladder. The barrel was hot glued and then secured in place with JB Weld.

A suction cup dart head was hot glued underneath the PVC and air bladder to absorb some of the shock and protect the weld that holds the barrel in place.

My friends and I usually play in dimmed lights indoors, so I added a green flashlight I had lying around. It shines in the same direction as the barrel and pretty much goes where the darts go.

Have not been outside for a range test yet, but darts seem to go about 35-40 ft depending on how hard I hit, which is perfect for the type of indoor nerf I usual play.

The only thing I'd want to change if I did this again is to make it more of a buckshot, not just one dart.

Very clever. This is a cool project.

Have you considered weighting the base down, so it wouldn't move if you stomped on the stomp rocket part? If you could get it more fixed in a spot, it would be neat to be running away from a few people and step on it as you're running away in order for it to shoot behind you.

Thanks!

I'm sure that's a possible addition I could make to this. I'll think about it and see what comes of it.

I know that this thread is dead, but I finally got around to revising this design to increase dart capacity and allow for what Ice Nine described above. I figured I'd share that progress.

I bought another "stomp rocket bladder" off Amazon ($3), which actually turns out to be a foot pump for exercise balls, and made this 2.0. The new version shoots up to 4 darts and uses a larger bladder than the original. The larger bladder allows you to step/run on it. I don't recommend that however, because it's an awkward maneuver that yields less power than just whacking it.

 

It still operates the same way in general however.

 

The barrels are 1/2" PVC, with 1/2" CPVC supports underneath. I used two old tagger heads as extra cushioning for the supports. I used JB Weld to lock the barrels into place.

 

 

Here's a size comparison to give you a rough idea.

Ranges:

Shooting 1 elite out of each barrel = 60'

Shooting 2 elites out of each barrel = spread of darts between 30' & 40'

 

It's of great use during indoor wars/cqb and is a pretty straightforward project.
