So this is a normal nerf rifle. You have your scope, magazine and your bipod. This is a really
cool toy but I felt it was missing something. I felt it was missing power. So, I decided to fix that.
So the nerf gun I bought fires these darts, this is a standard nerf icon dart. Now the only problem is
it's really hard to hit small targets with a dart that small. I could either become a better shot
with a nerf gun by practicing or I could just make a bigger nerf gun. This is the dart the new nerf
gun shoots and as you can see it's a lot bigger and as we all know bigger is better. So, this nerf
dart is basically one and a half inch pvc pipe runs along the inside core and then I have these
3D printed caps that fit over the pipe. Then, all I do is epoxy foam around the exterior and then
you get this really nice nerf dart. Another pro of having the world's largest nerf gun is that you
really don't have to aim anymore - you simply point the gun at the target and it kind of goes away.
The first step of this build was to model everything in CAD. Once I finished the design
process I could transfer my design to wood and begin cutting out the shape of the nerf gun.
A majority of this gun was made from plywood however I did 3D print a lot of the more
complex geometry such as the scope, bipod, bolts or anything that I didn't want to make out of wood.
Once I had the basic design of the nerf gun assembled I could begin adding the
more detailed parts such as the side panels, 3D printed bolts and any other
pieces of plastic that would make it more accurately look like the original nerf gun.
Now it's time for the fun part, final paint.
So right here I'm masking off all the parts that I don't want to paint gray and then after
I do all the gray parts, I mask this off and do the yellow and any of the more detailed parts.
Now, if you're watching this nerf, I don't plan on selling this gun so please don't
sue me but I really had to add the official nerf batch to really bring this gun to life.
Also if Mr Beast or Dude Perfect wants it - hit me up! Measuring 12 and a half feet long and
weighing over 200 pounds - this is the world's largest nerf gun. This nerf gun can project
12-inch darts at over 50 miles per hour at half of the gun's full power potential.
For safety reasons, most of the shots shown in this video were taken at half power or 40 psi.
This gun is capable of shooting over 80 psi. It's also 300 percent larger than the gun it's based off of.
So this is how it all works. Air is stored at 3000 psi in this paintball tank right here. The
air passes from the regulator through the silver hose, down to this first air valve. When you push
this handle, it will allow air to flow through this valve and into the main firing chamber where the
air is regulated to 40 psi. Starting right here, down to right about there, is the firing chamber
for the gun. At this point, all you have to do is pull the trigger and air will be released down the
main barrel. Now let's talk about the electronics. So to power up the system, you're going to turn the
switch to the on position. Power is regulated from 5 volts down to the Arduino pro mini down here and
what this Arduino does is it controls the signal coming from the gun's trigger and when you pull
that trigger the signal is sent to the Arduino and it passes to a Servo which releases the
secondary air valve which in turn clears the air down the barrel, propelling the nerf dart forward.
Rounds are loaded from the front of the gun and pushed to the far back with an aluminum rod.
Now that we know how it works, let's see how far it can shoot.
Three, two, one!
Now let's see what the gun can do at full power or 80 psi. One, two, three!
That did a lot more damage than I thought.
It's a good thing we had a backdrop there because it blew right past the first stop. So we're gonna
shoot this block next and we've never shot this kind of full power before so I don't know what's
going to happen. I think we might have a shot of breaking this if we hit it on the side right
here and not at this support area right here. I think if we hit it right here we'll be okay.
So we're going to try shooting it with a solid core tip dart it's the heaviest start that I have
right now and if anything's gonna get through, it's probably gonna be that dart. One, two, three!
So, this is what's left of the cinder block.
That's actually pretty impressive, and the rest of it fell down there.
Hello, my name is Michael Pick and I run a YouTube channel where I make really cool stuff.
I studied computer science in school and worked professionally as an engineer
ever since graduating. Most of my previous videos have been either
miniatures or super-sized projects of normal items. For example, I made a super-sized nerf gun
and I made a miniature iMac computer. I'm also working on several much larger projects that
are very different than anything that you've seen before so if you'd like to
see that please consider subscribing and I'll be posting those videos very soon.
