[@ryanpallesen3569]

I think a lot of your problems with jamming at high speeds can be explained this way: When the dart leaves the magazine, it has incredibly downwards momentum. The more darts you're trying to shoot, the faster your magazine, the more momentum. Your darts are a flexible object, and you're only catching them at the tip with your launcher, so the momentum in the bottom is continuing, which then causes friction and jamming. This is also the same issue with the tips being brought upwards and angling strangely. This might be fixed by changing the angle of the drum, either making it horizontal to transfer the entirety of your rotational energy on release into forwards momentum, or diagonal to just cut down on the amount of energy that you're having to mitigate/deal with on the dart when it is released from the magazine. Custom hard rubber darts or solid darts might also solve this issue, but that doesn't seem like an option.

[@3DprintedLife]

You're exactly right, the darts are moving at nearly 7m/s when shooting at 100/s rate. And they have around 2-3 ms to change directions and extract from the mag, then

[@sharkbyt8806]

@@3DprintedLife I wonder if you could use a harder, thinner dart in order to counteract this issue. I don't have the resources to try this but it would be cool if someone did. The downside is that they would hurt a lot.

[@draco6349]

@@sharkbyt8806 i think at this point making the darts hurt more is perfectly reasonable, if only out of sheer spite for the project. xD

[@ironbeagle1610]

@@3DprintedLife I wonder if you could integrate the mag and the feeding belts more closely. right now there a lot of space between them and they don't really join together. maybe you could somehow make the feed belts mesh with the magazine by having cutouts in the mag for the belts to sit.

[@paranoidzkitszo]

What if a "force" was added from the back? So, the dart isn't just snagged, dragged, bagged, sometimes making it, other times just causing ones' self to go mad- what if a slight flow of air was being generated by a fan from the back to kinda push it along especially at the higher speeds so that it's not just the front of the dart being grabbed by the shnoz and dragged into criticall velocity like a brat child getting caught stealling by thieir moms at the candy store/ toy store....

[@marekfiferna]

Important note about drone ESCs: Their current rating is based on air cooling. Without cooling, expect them to blow up even below that. And if your throttle signal is jittery as hell, they (or the motors) are gonna pop too

[@3DprintedLife]

Yeah I expected the heat from not cooling them, but they only run at high load for a few seconds tops so shouldn't burn out. I did discover a bad signal would kill the esc's haha but that was resolved by switching to the teensy!

[@Cam64viper]

Yes! More! Perhaps, since you already have the rotating design working, you could make an RPD-style belt inside a drum the same size as your current drum, and make it belt fed? I don't expect it to be nearly as fast, but it would be a fun challenge

[@3DprintedLife]

Definitely could modify it to be belt fed, would be an interesting way to increase cart capacity. But no way it’d top Gatling Tommy’s!

[@jackermis3104]

​@@3DprintedLifehmm i may try to take a old leafblower do something like that, have all the air channel into the feed system, aending the dart forward into a flywheel system like yours, and out of a barrel with the leftover exaust of air or co2 from the blower. Either way im not sure i can really make this possible, but i might try. For i have zero knowledge of programming, but maybe i can make it completely mechanical. Mechanical mags, full speed flywheels (sustained fire may have cooling issues, water cooling or heatsink?

Time to create an automated mag-loader....dump the darts in a hopper and it sorts them to be the right direction and then feeds them into a mag....

[@wistralis7387]

One exists from CreateWithEzekiel for half length darts

[@lukasp.7663]

Oh man this is awesome! Incredible that you've pulled this off. For a more stable flight path you could look into getting a SCAR or BCAR (basically it's rifling for Nerf), I would recommend using a BCAR with a flywheeler because it has a way lower impact on muzzle velocity.

[@covodex516]

Once again I highly appreciate all 3D printing content creators who openly show their journey through all the failures until they finally archieved a working device. I really dislike it when people act like its just printing, put it together and there it is. Integration hell is something every maker will encounter at some point, usually in everything when its even just mediocrily complex. Many of them will give up out of frustration and I find it important for them to see that even "professionals" have these exact same issues as they have.

[@Rebar77_real]

Teflon rails as guides to help them from catching and throwing them off bore? That it worked that well kicks ass.

[@3DprintedLife]

Teflon does work great against the foam but it’s terrible against the rubber, still too much friction there

[@Rebar77_real]

​@@3DprintedLife Ah nuts. How about a wedge shaped belt to feed better as the round comes down, or even full V-shape to capture the shape of the tip? Do the initial belts need to be that fast? They only need to pluck the round out of the magazine to feed to the next drives, right? Are the belts too long for plucking duty? Belt shape to grab the tip better and not so fast. Let the secondary or tertiary drives accelerate it, type thing. Just throwing thoughts at the wall, cheers all!

12:00 Now that I think about it, the way you spin the mag is similar to how a revolver works by spinning the chambers... with that insane fire rate this thing is more akin to a mini revolver autocannon Awesome and scary!

[@justOVERCH]

9:25 I think a physical button on the bottom would be better than a servo

[@arcanealchemist3190]

the servo allows it to be a smart-blaster, and eject the mag as soon as its empty. which isnt practical but does add cool factor. pretty sure this design does allow for both the wedge and a pull-tab at the back for manual ejection. id be suprised if this isnt already in the design and just not covered.

[@teresashinkansen9402]

[@drflux]

This is absolutely Amazing! I would love to get my hands on this! Great work!

[@quantumview8151]

There are some changes that are necessary to make. 1. Current limiting. It will jam at some point huring regular use. 2. A jam door and improved belt frame to more easily clear jams. 3. (Not as necessary) Perhaps the dart belts could go at a speed proportional to the fire rate.

[@SSTC.]

Why didn't you use wide GT belts for the belt drives? Widths up to 15mm are available. Perhaps they would have performed better at such speeds as they don't stretch as much. And if you turn them inside out, the teeth would provide extra grip. Also, a pair of flanged bearings with a regular bearing (or a spacer) between them would work great as a pulley in that case.

[@inoob26]

Maybe he wanted a drum mag design from the start

[@lady_draguliana784]

@JeorgSprave over at the slingshot channel has tips on how to make a cheap and easy projectile catch. just need: -medium cardboard box -towel -box knife -tape (optional) -fold in or remove all but one flap around the opening -cut 2 slots into the side of an amazon box about 2 inches or 4cm apart perpendicular to the opening, on the side opposite the remainder flap, -slip a towel into the slots, draped over the middle bit (leave the towel on a hangar to stiffen if needed) -dangle the towels layers like curtains, passed the remainder flap, which you can tape up to make a basin to catch your projectiles that's it, takes 10 to make your first one, and I've made them in just 2min. you can also just cut one larger slot if you have a simple triangle hangar that's longer than the width of the box.

[@DIYDSP]

I lol'd at "consumables." Great work!

[@atacstringer8573]

Insanely Fast Fire rate and the design looks really cool also

[@ben.alldridge]

Perhaps consider two belt stages. A slower catch belt feeding into a faster propulsion belt is how I've seen similar mechanisms work well before when the item is flexible.

[@tomarmadiyer2698]

I pondered this too Also thinking of spin.

[@OnlyXaM]

15:05 a dart lands upright lol, its just under the barrel

[@ChainsawFPV]

I love that you can put so much different music on the ESC's. Bluejay is the best firmware for startup songs. Try the Ovonic V2 130C lipos. They are less money then a Tattu, and the same quality. And way better then those CNHL. Black's.

[@theworkshopwhisperer.5902]

Here's an idea maybe an RC tank with any variety of strange wheels screws multidirectional drive and a mega dart launcher. The fun bit is some kind of overcomplicated and deliciously over engineered autoloader for the mega dart.

[@Diesr]

Angle the feed belt a bit in the opposite direction of the turning so the feeding is gradual and make the belts spread and then push inwards a bit so they can slowly grab better

[@Demonanimator]

In my opinion that is a very narrow barrel those darts are expected to pass through, which may be why they sometimes get jammed in the flywheels. The narrow barrel space may also be causing dart drag, which may be why your darts aren't traveling straight when fired.

[@ironbeagle1610]

this is such a cool design. once you get it flushed out you should definitely order a custom PCB for it so you can make the body slimmer and integrate everything better. also one suggestion is to make the mag release purely mechanical, while the current design with the servo is really nice, a mechanical one might take up less space and have less weight.

[@VictorGarcia-ug5jn]

I think maybe make a cone where the mag loads in to the treads, the bearing ramp is awesome but the heads are getting stuck on that first bearing, if you do a cone maybe it'll help

[@infinate_gaming]

Fun idea: make it eject shell casings (broken darts)

[@3DprintedLife]

Haha oh it kinda already does when it jams at full speed. It tends to rip a few in half and spit them out the other side before the mag locks up

[@infinate_gaming]

@@3DprintedLife ii guess, but i was thinking maybe more of a controlled and reliable sort of add on but that probably works too xd

[@nighthawkgaming2953]

“With over 100 rounds per second, full auto becomes a shotgun.” -some guy who made a cool quote

[@billymarmalade3263]

instead of a spring system, could you use centrifical force to bring the darts to the outside of the mag? youd most likely have to make the channels for them straight though.

[@hazza2247]

amazing that u didn’t give up given all the annoying little hiccups 🔥🔥 very cool project

[@nanastos18060]

Awesome job! Absolutely love it and all that hard work BRO… nicely done!!!

[@tech_of_steel20official]

I have a question, why didn't you use rubber belts on the belt drive? I don't remember if you explained it in a past video but I feel like it'd be a good idea compared to plastic, also with rubber belts you could have a very small belt side loaded into the drive to get rid of any problem with the belt expanding when sped up. Also for the jamming problem I don't know if it would help but you might be able to have a tube barrel with cut out sides for the belts instead of a open space where the darts can stray off the wanted trajectory, also another person has said the centrifugal forces of the rotating drum might be your problem, but I think this might be the solution to said problem.

[@RonaldMcDonald6969]

I think belt drives that contour more to the dart's round shape, or use 3 or 4 belt drives would work better

[@tcdenby]

I've been waiting for this to drop, looks awesome!!

[@walf6978]

You should use JST connectors for the wires. I've never gone back to dupont since switching. They're polarized (so you can't plug it in backwards) and have a locking feature.

[@3DprintedLife]

I did replace them with jst connectors, but a non locking variant

I hope engineering channels such as Stuff Made Here, etc. take on the challenge of refining your current design to work even better. After all, it’s only a matter of time before someone designs a blaster and mag that can do 1000 RPS. 😉

[@lisaridener7514]

I feel like you should’ve not over powered servo might like break sometime soon because of it but if it’s like a gap thing then yeah I would get it but it seems like you wanted to keep it there forever so I don’t know and also you should do like the ultra darts because they are way stronger than the regular dartsbecause they’re like fully filled up with like the strong like foam, but I don’t know he’ll be the best though

[@goldenandesite]

You could add rifling to the barrel as well as the stage that rotates it.

[@sokjeong-ho7033]

Based dedication to making it easy to skip sponsored sections 👍

[@Napoleon_Bonaparte1804]

For the darts going all over the place, you should put a bcar. A bcar is a type of barrel addon that acts like rifling.

[@siberx4]

These generally don't work that well on flywheel-based blasters; they rely to some degree on the air pressure of a typical spring-and-plunger arrangement pushing them from behind to ensure the darts travel through the bcar reasonably straight and don't lose too much velocity doing so.

[@shatteredskies191]

⁠​⁠@@siberx4they work fine on flywheel blasters but are a bit more touchy. On a springer, you usually have air ports before the bearings, so that’s not relying on the air pressure either.

[@maweitao]

​@@shatteredskies191Air pressure is not a factor in flywheelers; the only thing imparting momentum is the flywheels themselves. It's why the only marginally effective BCARs sit just ahead of the flywheel cage. Good dart alignment is one reason, but the bigger issue is that anything ahead of the dart, be it bearings or the barrel is doing to drop FPS. Springers, on the other hand, are entirely dependent on air pressure. It's why barrel length is an important component. It's so much of a factor that muzzle blast can disturb a dart's flight path and that's why some BCARs are ported.

[@shatteredskies191]

@@maweitao correct. But anything after that porting on a springer will also drop fps. All I’m saying is that bcars can be used effectively on flywheel blasters.

[@jacobnewman3152]

Maybe you could add a auto tensioner to the belts, similar to an automotive tensioner on timing belts or accessories belts.

[@3DprintedLife]

These belts are elastic so that doesn’t help. Tension can be adjusted by modifying the belt loop length. This is also how it’s done on cars typically for belts running to accessories that are under less load

[@jacobnewman3152]

@@3DprintedLife I didn’t expect you to get back, that makes sense though. Watching the slow mo with the belts kinda almost jumping around. Which maybe had an impact on how the darts fed in. Also do you plan on making this more reliable in the future?

[@blendervendor2220]

this is actually kinda cool but still I think it's still a bit of an over complicated design. Still best one out of the group (not including the moab. that one wins purely on style points).

[@Scott.E.H]

It's BEAUTIFUL. Looking forward to whatever you're cooking up next.

[@3DprintedLife]

It involves irresponsible amounts of current running through tiny pcb traces :)

[@Forakus]

Really cool project, maybe a bit too fixated on the 100 darts/sec but that's understandable. I think adding additional features and improving reliability even at a lower rate of fire would've made a better end product, but of course a much less cool youtube video title

[@nucleartime]

Have you tried using EPS darts? They're a bit more expensive, but I find they feed better on finicky blasters due to being stiffer.

[@3DprintedLife]

Ah no I haven’t but that does sound like it would help!

[@HavocStylesJoe]

12:23 DA Torque! 😲

[@3DprintedLife]

It’s a 2kW motor :) absolutely overkill

[@Gunbudder]

why not go to track fed like a real minigun? they have to use a track that rounds slide on because any other method is too slow or unreliable for feeding. and you don't need extra barrels either like a real minigun does because your barrel doesn't factor in to firing a dart at all (you aren't even using gas expansion to move the darts). i'd move towards a huge carousel that feeds a track into the "action" of your two belt drives, and then a rotating pawl that grabs darts from the track and puts them into the belts, then moves out of the way (exactly how the minigun's action loads). what you have now is like if you deleted the track and the loading system on a minigun and just threw rounds from the carousel into the open action lol

[@aze4308]

you should make a cinematic for this gun to show it off!

[@willcubemakes]

Awesome project 👏

[@metalsuccattack]

without the need for a 100 dps blaster, this drum design does seem really cool for a high capacity blaster and would rock for someone to build a tommy gun style blaster off

[@3DprintedLife]

Setting it to 10 or 20 darts/s fire rate is actually surprisingly useful! Though a little unweildy for actual use :)

[@8lives873]

You could reinforce the darts so they were stronger and heavier and wouldn't bend and you could move the belt at a faster speed
