Brings back memories of middle school.. Just hear me out. Around 6th grade is when myself and a lot of buddies got into airsoft. Anyone who plays with airsoft guns knows the BBs get absolutely everywhere. Well they ended up in someones pocket one day, and we got the bright idea to start shooting them at eachother with Bic pen tubes- surprisingly accurate and powerful, its like they were made to work together. Me being the crafty little bastard I was, created a version of this gun from a pill bottle and a few melted pen tubes. Fill the pill bottle with BBs, pressurize pill bottle with breath, and presto- you've got yourself a machine gun. My uncle had a sand blaster, and explained to me how it worked while we were cleaning up some old 2 stroke parts or something. Was really proud of myself when that little device worked, and excited for the shenanigans to come. Eventually the classroom blow gun airsoft war ended with 6 of us getting a 10 day suspension, we reverted back to the classic paper wasp after that. Good times.

This brought back some memories. Back in the 80’s there was a multi-state hobby group called Hull Busters. Think 3’ scale RC WW2 warships…mounting Freon (yeah, Freon just go with it) powered BB guns & “magazines” w 50-“unlimited” BBs each. Goal, sink each other’s ships (1/32” balsa hulls per rules). Early versions were servo activated single shots. Then someone got the bright idea of using O rings..come to find out the pressure control wasn’t quite fine enough and you’d get say 3-10 BBs squirting out w one servo activation. Then someone said, hey that’s a great thing…just keep the servo open and fire all the BBs in one go..the arms race was on and the ZIP gun was born. Why ZIP? Cause all the BBs would empty out at once so quickly it was almost instantaneous and sound like an extremely short blurp or somewhat high pitched “ZIP”…more like a 10th of the “Z”. Results were rather than an occasional hit, your were likely to see about 3-8” of yours (or adversaries) hull disappear almost instantly. Yes, we had onboard pumps, and depending on class ship & # pumps allowed, what became known as the “penny pump” could keep her afloat, w water streams shooting 3’-6’ in the air, even with huge sections of hull missing/holed. Ah, those were the days. I think there may be a few Hullbusters groups still active at least pre-“virus of unknown origin”. Have a good’un.

[@jessefurqueron5555]

Looks like the name may have morphed a bit from “hullbusters”. Try searching for “hullbusters rc boats BB gun” in “$moogle” or duck-duck. Back when I was involved, we only had Usenet not internet, most info was in a monthly newsletter (which I still have, somewhere), I think the editors name was “Fleugal”, he was based here in Dallas in the early-mid 80’s. Don’t forget, in this hobby if you lose (or even if you win!) you might have to go swimming 😁. Yep, auto electronic shutoffs got popular real quick. Hobby was big enough at the time that we’d have regionals & nationals. Popular ships to build were Tiriptz, Bismarck, Prinz Eugen etc. I built the Deutchland (Lutzow). Building materials were Baltic Birch ply for ribs, main sub-deck. Balsa for all hull and vertical superstructures. Each gun had a mini gas (Freon) cylinder (mine were ball shaped), BB magazines were just brass tubing (the entire magazine was pressurized), RC electronics, simple “water detection” switches for pumps electronics shutoffs etc. was amazing how fast the “weaponry” evolved just a few years.

Beautiful! You might not be able to avoid those shots clustering, unfortunately, if they are caused by vortices - similar to the way that water, when falling, will fall in a steady stream at first, then the surface undulates, which causes it to form globs that fall in clusters. As a pellet moves through the air, in a region which was not previously disturbed, it will create a toroidal vortex in its wake; when the next shot follows close behind, it will be dragged into the wake of the leading pellet; the 'train' of pellets act like a line of Mac trucks on the interstate, drafting behind one-another. Eventually, however, the gun's angle has changed enough that the next pellet is *not* captured; that pellet acts like a new lead-truck in an entrained cluster.

[@stevep7346]

Coming from a more traditional ballistics perspective, my first thought was barrel harmonics, but this seems like a strong theory, especially for low-mass pellets. You could test this by making the barrel axis fixed and moving your target instead, so entrainment would pull pellets in a straight line and could be neglected. Or just use a high-speed camera, which I would think would be easier.

[@IVAN_ENT]

@OskarHersch i understand itd be alot less energy than powder fired anything ,but even this would fuck up an fpv quad if you could just target it properly in my opinion, one of my hobbies is building fpv quads and flying them freestyle for a few years now, and while I haven't shot at one I'm pretty aware of what abuse they can take and have had to replace many a part ,they are pretty durable sure but that's mainly just the carbon frame everything else like props battery or front cam are pretty exposed/ fragile and if we are talking about russian lancets or similar you would just need to damage its control surfaces which I imagine are light weight enough. Also I'm just talking about very close defence as they get too close just zzzzap em haha I doubt this could have any real accuracy at much range at all

[@MatthewZelek-iv8tb]

Steel loses energy too fast. Your “close range” would be maybe 50 yards. You would be better off with .22 pistols on a rack cam fired. .22 machine guns exist that have 200+ round drums, a few of those mounted correctly would serve your purpose, easy 500m+ range on softer targets like drones.

[@terke1230]

Have you considered that your firing rate might not be that uneven, but that your barrel might be vibrating at some harmonic frequency? That would explain the vertical spread as well as the horizontal grouping.

[@benjaminshropshire2900]

Interesting thought. Another resonance possibility; eyeball math suggests that there will be between 2-4 BB's in the barrel at any given time and if they are interacting with each other they might be creating a periodic variation in muzzle velocity. (Easy way to check that would be to have two sheets of target 6-8 feet apart and check if the groupings are different at different distances from the muzzle.)

[@kev7777777777]

That's possible. Someone else also mentioned that it could be alternate rotation of the bb's spinning as they go down the barrel causing them to curve in different directions.

[@Oldtanktapper]

Or it could be a pulse forming in the air supply/ammo feed from back pressure caused by rounds not exiting the barrel quickly enough. A bit of tuning with air pressure and barrel length might help?

[@davidmorganson4327]

It may not be the firing rate causing clusters. It may be the sweep motion system which is pneumatic. You have an intertial load when the air cylinder first begins to extend. You hit peak pressure here in the pneumatic system. After that you get a pressure oscillation similar to water hammer in a plumbing situation. Water does not compress, but the pipes flex which causes an oscillation similar to a pneumatic system. If you switch to a hydraulic motion system, and use short tubing, you will see the cluster effects diminish. A cheaper way would be to increase your air cylinder diameter and observe the difference.

[@Choober65]

Try using an ultrasonic transducer attached to the ammo feeder. This might stop the ”clumping” by giving a smoother feed into the barrel

[@dwaynesykes694]

An ultrasonic transducer isn't the right tool for the job. You need something that outputs a bit more power at a lower frequency, like an industrial vibrator made for compacting sand/concrete, or a slightly less industrial smaller version.

[@llahneb10]

Something that would be super interesting to try given the mechanical and inconvenient limitations of physical movement could be to put a high voltage on the barrel so that the BBs get electrically charged - can then be slightly deflected by electrodes outside the barrel. This would allow near-instantaneous control along two axes. It might additionally offer interesting diagnostic data by hooking it up to an oscilloscope. The amount of current draw should be indicative of the firing rate

[@DBurgur]

Unless your receiver is shooting groups of BBs, rather than a steady stream of individual BBs, I have a different idea to explain the gaps between groups at high rotational speed. The barrel, especially at that length, is quite flexible. Assuming you are rotating from right to left, during the constant acceleration phase, the barrel is flexing to the right due to its inertia. When acceleration decreases (nearing constant velocity) the barrel attempts to return to its neutral position and will oscillate flexing right to left to right and so on. Assuming the front mount of the barrel was added to add rigidity, and reduce the unsupported length of the barrel, the frequency at which these oscillations happen can be very high. Therefore, while the gun is being rotated towards the left, towards the end of the travel, the barrel is moving further left than the actual direction of the receiver and then bouncing back towards the right where it has previously fired shots. This could very well look like groups of shots with spaces without shots in between.

[@Timestamp_Guy]

I commented basically the same thing. Also, BBs, unlike lead pellets through rifled barrels, can have lateral spin issues since the sort of "roll" down the barrel which can cause them to "curve" like a baseball. Even if the flex in the barrel isn't enough to shift point of aim that much, having the bbs coming out with alternate left/right spins could compound the effect.

That's an interesting idea no one has come up with yet, alternate spinning of the bb's. That could be possible.

[@pizza6447]

bro i love this voice. its so easy to listen to and so calming. he talks about guns (airgun but still) yet id listen to this while falling asleep. damn

[@DigitalNeb]

Well, that gets my sub. Nice work man. Very interesting.

[@oooooof5023]

The shot grouping looks like a barrel oscillation, potentially from the actuator or the firing impulses? Or both.

[@charleyfarley68]

It could be a dynamic funneling of the rounds, A real Slow Mo of the rounds flying will tell.

[@Michael-uj2fb]

Hopefully some helpful advice. To help with gaps in grouping, round ammo is not ideal unless you can create a spin on the BB. I'm looking forward to watching more as this is my first video of yours I've seen.

[@codyramos3200]

The guy built this gun 20+ years ago. .

[@DoctorTemblor]

It is amazing how you managed to make this video like this without using high speed cameras

[@iplaygames8090]

this has such old internet vibes, yet came out in 2023. Godspeed

[@airgunningyup]

would love to see the internal mechanism.. Feeding the BBs to the chamber at that rate is difficult.

[@benjaminshropshire2900]

What would be really cool would be to see the insides working in slow motion to see what's causing the bursts. Does anyone know if the CCDs in high speed cameras are sensitive to x-rays? This seems like something @AppliedScience might be interested in figuring out.

[@MatthewZelek-iv8tb]

I can tell you already the bursts are from pressure variances and or turbulence.

[@rangerdanger222]

It could be binding of the bbs.

[@RBMK-ym4dm]

@@benjaminshropshire2900 the X-Ray source you'd need to use to use to film that is only available at National Labs. You need a particle accelerator to get an x-ray source that bright.

[@benjaminshropshire2900]

@@RBMK-ym4dm A few quick searches suggest there are man portable, commercially available X-ray units that are powerful enough that they can inspect large steel weldments in a reasonable amount of time. IIRC those systems are *well* into the "don't stick any part of yourself in there that you would mind falling off" power levels an you can get full motion video at exposures below that used for normal medical x-rays. I'd totally believe that you could end up with rather grainy results, but I'd have to call [citation required] on saying you would need national labs level sources to get anything. I suspect some sort of x-ray strobe source synced to the CCD would end up being part of the operation. You might not get high frame rates from that, but even lower rate very short exposures could be very useful in seeing what's happening.

[@jasont80]

Amazing! Clean design. I'd love to for you to break down your feeding mechanism! I feel like that's where the improvements need to be made.

[@tylergood9168]

scrolling through the comments to see if anyone mentioned it. I agree. It was not mentioned from what I heard. he couldn't possibly be using gravity...(?) with all the air, there must be a charged feed. ...electromagnetic? super bitchin. great stuff.

[@trollmcclure1884]

there's no second hose or container full of steel BB's. He may be feeding it through the air hose somehow. Maybe the "magazine" itself is pressurized. One hole keeps supplying the air while pushing the balls and the second hole goes out. It's a mystery but it cant be too sophisticated

[@MP-qn1jw]

A masterpiece. Thanks!

[@taldal1923]

I've waited years for this

[@vne5195]

Maybe the firing rate is consistent, but the barrel is oscillating (bending/whipping) fast enough to cluster the impact points. I would certainly expect greater horizontal oscillation due to the acceleration imparted by pneumatic panning mechanism used to move the gun from right to left. Perhaps it is possible to to plot the audio wave form of a series of shots to better understand the variation in firing rate. Audacity is a free app that can plot the wave form of audio files.

[@back40snuts]

300fps or even 120 frames per second would have helped significantly, majority of smart phones can do around 240 no problem, some newer ones 480 and even 900+

[@heinous70]

I think his work deserves an upgrade. Several years ago, in an attempt to get some interesting stills from the range, we shot some slow-mo footage. We not only caught the fire and shell casings shots we were after, we caught one frame of around in flight, a foot and a half away from the muzzle. With a Samsung phone

[@toad3222]

Brother

[@lifeofgarrett]

That is by far the best thing I have seen today

[@copperry4381]

This was pretty great nice work

[@matthewloxton2570]

Cool Two points: 1. you cant ignore the slow startup shots, those need to be kept in your calculation of overall rate 2. Moving the target is maybe a better approach than swinging the gun. Many competition targets have a journal roll behind that is essentially a big roll of paper unrolling on the one side and being rolled up again on the other side. That shows whether more than one round went through the same hole on the target, and also shows up any fluctuations in the firing rate.

[@pumello]

I bet that a roll of paper would be a lot cheaper than all the (not) coke cans too haha

[@GeorgeTsiros]

the starting delay is due to the location of the valve. Place the valve closer to the barrel, so that the hose maintains pressure, there won't be any perceivable delay.

[@CorePathway]

No he does not need to keep the slow start. There are no rules stating max rpm is defined by anything more than whatever time he chooses.

[@teejin669]

Why can't he ignore the startup shots?

[@johnathandavis3693]

What happened to the guy that remarked "This has been done a million times"? I guess he went to troll heaven👼

[@stephenaddison7212]

Absolute insanity Well done

[@jrhamilton4448]

I think it's safe to say sir, those cans that survived won't be bothering anybody again anytime soon.

[@Bantallas]

Like the ingenuity with the limited Equipment.

[@watervapor42]

this is awesome keep up the work

[@user-mg5dn2zt6e]

Came across this video, will say hats off to ya my friend

[@brtt_]

If my math teachers had told me I could use math for this, I would have paid more attention.

[@flugruger25]

The idea of 20 barrels firing for a whole minute gives you a perspective how much 2 million actually is

[@dreaticadta806]

you are a genious, do you plan to post a blueprint or something for explain your work ?

[@glennbrymer4065]

Nice! Well done sir, well done!

[@AdmiralSym]

Metal storm! What a classic YT video

[@SJR_Media_Group]

Gotta love a man who knows how to 'crank the numbers'.... fellow math and physics geek. You sir have a bright future...

[@WhatSmellsLikeToast]

I just watched your video about the valve, really great work! Do you have somewhere we can learn more about this project? CAD files or anything?

[@lukephilpot5660]

That's mental. So good!

[@starpuss]

Keep up the good work!!!

[@feelup1111]

The gaps will be down to the harmonics of the barrel. Really good job, next level skills.

[@jacob_90s]

I was about to lose my mind at the thought that you weren't going to show the coke cans in real time. Clutched it at the end though

[@niklaswo]

I just imagined you not showing the real time shot at the end and it literally twisted my gut 😂

[@jakelandry5645]

There is NOTHING to be disappointed about regarding those results my guy.

[@Travistyj]

Just Wow, really cool man and great job

[@davidwitkopii291]

Awesome man!

[@ArnieMcStranglehold]

Well, this man has created the current, definitive, "fullest auto".

[@meneerjakob]

Very cool! How does it work?

[@smagnusen]

I would love to see a long format version of your development process
