A while back I got to thinking about how it would be so much easier to fire my blaster when running if I had a more stable platform from which to fire... The result can be seen below. The G.S.S. MkI (Gyro Stabilization System Mark One) It has a dual switch system, and is lined with foam to help keep the noise down. I have also included a schematic of the basic power-train, and systems. The Green represents the switch, the red and blue the wires. The entire assembly is powered by one nine-volt battery. The motors and flywheels, indicated in teal, are arranged back-to-back, and are wired so that when viewed along the long axis, both flywheels spin in the same direction. During tests, it did in fact impart a stabilizing effect to the blaster. Ideally, this device would be best suited for use when firing from either a vehicle, or when moving at extreme speed. the MKII will have more powerful motors, and larger, possibly spherical flywheels. The gyro effect is most noticeable with smaller blasters, less so with larger ones.

I used the casing for one of the scopes you get with a longshot, but any scope will do, the advantage is that when you use a scope, you retain the clips, and the device can be attached to the tactical rails on any N-Strike blaster.

Have you ever held a gyroscope? They have this funny property of not wanting to be moved, so they cut down on the movement the gun goes through, theoretically making it more stable and accurate. Megaprops for building this Mega, but I get the feeling this is a high-work low-payoff sorta build.

Does it still attach to the gun via tactical rail

Hmm....
A little reading goes a long way.
As for the Gyrostabiliser, I love it! Looks like it was a pain to build.

Thanks for the props, and you're absolutely right, this is a high work-low payoff build. It's more of a proof-of-concept build, proving that a nerf blaster can in fact be stabilized by a gyro system. The next step is using faster motors, and heavier, possibly spherical flywheels to see if the effect can be magnified to a degree where the gun is locked in place, or at least much more stable than it is now.

It looks like replacing the battery is going to be a pain once it dies. Also, what n-strike attachment is that made out of?

He stated already that it was made out of the scope you receive with the longshot. This is exactly what Niteshot was talking about: "A little reading goes along way"

I don't know much about gyroscopes, so forgive me if I'm totally wrong, but wouldn't the effect change based on where the gyroscope was attached to the blaster? Like if you moved it to the end of the barrel instead of where the rail is does it become more stable? Or less stable?

This thing is pretty cool, I'd love to see somebody use it to make accurate shots from a bike or something.

If Mk.II is more successful, would you be contracting these? This is a very cool concept that I would love to see in action.

Actually, not really, the endcap on the long end is just pressed in, it comes right out, but stays locked in, because it has a grooved flange that fits inside the main body of the Gyro.

Interesting concept, though I expect the result would be the opposite of what you were going for: the rotational mass would make the blaster slower to aim (since it will resist quick direction changes), for example when snap shooting multiple targets with a semi auto. And I sincerely doubt it adds any type of stability to a bouncing/bobbing/weaving person on the move. I can back up this statement by demonstrating that no actual firearms use such a device, and surely a more stable firing platform (if it worked) would be in use by the military.

Gyro stabilization is something more commonly used on tanks IIRC. Still, an interesting use of an otherwise uninteresting attachment. I have one question though- wouldn't the stabilizer be more effective if the two flywheels spin in opposite directions? If it was strong enough and they both spun the same way then if you turned on way it would pull your aim up, while if you turned the other way it would pull your aim slightly down. While if they spin opposite ways you'd maybe get less up/down disruption from the gyro's bias? I don't know, but regardless, this is fairly clever.

EDIT: Something else which comes to mind as a possible usefulness of this- a weak stabiliser would not so much pull your gun around as it would give you very positive feedback when you do move your gun. IE, you'd be able to instantly feel if you aim is wavering while moving, etc.

That may be the case... But it still works. I have tested it extensively, and, so far as using it on a smaller blaster for snap shooting goes, you're right. But, it's not really intended for that. The gyro is intended for attachment to a long rifle type blaster, like my "Shattershot" or a similar layout of very powerful springs, very long barrel, and high accuracy. It would be used for shooting from a moving vehicle, or for scoped-in shots while walking towards or away from a target at long to very long range. If you take a look at the Shattershot, you will notice an additional tactical rail has been added to the lower surface of the forward body of the blaster, on the blue part. That is the ideal position for the gyro, or some place close to it. Certain models of Nerf blasters have a rail in this position already, or pretty close. That is where the gyro can do the most good. The intent is to make the blaster as stable for sharpshooting when moving, as when you are standing still.

What actually made me even read this post was the title. As someone that has been building/flying rc helicopters for years, I am aware that compact digital gyroscopes have become very inexpensive (even the 3 axis ones). What would be incredibly friggin cool would be to actually use them to stabilize the firing platform. The whole idea is that they are capable of making tiny adjustments to either x,y, or z axis hundreads of times a second, ie much much faster than a person is capable. Using this technology, it would theoretically be possible to construct a firing platform that could keep the barrel pointed on target irregardless of the direction or movements of the nerfer holding said platform (much like watching the turret of an M1A1 stay pointed at its target while the hull of the tank transverses uneven ground, changes heading, etc). I believe my idea is vastly superior, and would appreciate you getting to work on it right away :blink:

Edit: I'm sorry, did you just say

It would be used for shooting from a moving vehicle, or for scoped-in shots while walking towards or away from a target at long to very long range.


Where the fuck do you nerf? From moving vehicles and such I mean, and who does these vehicular wars with you? Do you host Mad Max Beyond Thunderdome scenario games? I want to play.

Well, the "From a Vehicle" part is a little over the top, but the idea is still sound... I think. (Perhaps from the back of an ATV or pickup truck Halo Style...) Regarding your "Total Stabilizer" idea, it could work... In fact, I had been toying with a 4-motor design, with either the motors arranged in an "X" configuration near the blaster's center of mass, with the barrel in the exact center, or a design with six motors arranged in a "cube" type configuration. The only major drawbacks I can think of at this point would be the ridiculous amount of power such a system would require, and how you would actually wear it... You would need to wear something like a steadicam rig, to achieve true stability. And that's without worrying about the occasional errant crosswind.

Not just motors, servos, and only two would be required for complete 3 axis control (3 If you wanted a true "Target and Forget" setup that could rotate the barrel 180 degrees from your own heading). Incidentally, micro servos are not only cheap, they consume very little power. It is possible (to someone with even just a basic knowledge of r/c stuff). Not likely, but possible.

I think we're getting well into "Armored Mobile Suit" territory here... Add a motion sensor, laser rangefinder, and auto-trigger, and you have the makings of a War Machine-esque secondary turret you could mount to your back...

EDIT: I just had a mental image of Dual-Wielding Barricades, and having one of those things strapped to my back... Variable threat response anyone?
