It cost 540$ to fire this weapon for 12 seconds
Darts arnt that expensive youknow
Adventure force pro darts are 10 bucks for 100 darts and 20 for 200
@ManaHarrell-ep5eq you obviously dont know this refrence then. thats too bad.
Asumeing the conversion rate of 0.1 for one dart it would be 120 dollars
Almost into military budget........ Lmao
8:23 lol DuPont, they are hell... but a necessary evil
Jeff geerling? Damn 😮
pi man :D
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.
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
@@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.
@@sharkbyt8806 i think at this point making the darts hurt more is perfectly reasonable, if only out of sheer spite for the project. xD
@@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.
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....
Awesome! ... ... Wanna try Mega Darts or vortex?
Mega darts would be hilarious. But no :)
vortex or even just flat foam discs seems like it could get pretty ridiculous, might try designing something for myself
Rival/Vortex are the way! SO much quicker to pick up with those mesh basket things.
@@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?
@@3DprintedLifeeither that or i may try to make a rather nasty feeling shotgun
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
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!
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
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!
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....
One exists from CreateWithEzekiel for half length darts
Teflon rails as guides to help them from catching and throwing them off bore? That it worked that well kicks ass.
Teflon does work great against the foam but it’s terrible against the rubber, still too much friction there
@@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!
9:25 I think a physical button on the bottom would be better than a servo
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.
But then won't be as TeChNoLoGiC.
14:07 the fact that u managed to hit your own Dart is just amazing
Haha oh wow I didn't notice that before. Slow darts gotta get out of the way :D
@@3DprintedLife „I DEMAND YOU MOVE!!!“ - a fast dart once said
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!
I love DuPPa's I2C Encoder and I2C Encoder Mini because it solves all the annoyance with using interrupts to read the quadrature signal and lets you just read off an I2C register
I lol'd at "consumables." Great work!
@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.
Finally, I’ve been waiting so long for the update! So pumped!
When this came up on my feed, I thought it would be using Compressed Air, But this So much more complicated than that Kudos!
This is absolutely Amazing! I would love to get my hands on this! Great work!
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.
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.
I pondered this too
Also thinking of spin.
Is it just me or does this look like a bolter
For the emperor
FOR THE EMPEROR!!!!
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.
Insanely Fast Fire rate and the design looks really cool also
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.
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.
15:05 a dart lands upright lol, its just under the barrel
Maybe you can build a nerf lancer from gears of war with a nerf chainsaw congratulations for the project by the way
Fun idea: make it eject shell casings (broken darts)
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
@@3DprintedLife ii guess, but i was thinking maybe more of a controlled and reliable sort of add on but that probably works too xd
A big problem just might be the darts themselves.
The darts experience extreme acceleration and changes of movement.
The darts just can't take that kind of beating.
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.
Awesome job! Absolutely love it and all that hard work BRO… nicely done!!!
I've been waiting for this to drop, looks awesome!!
lol I just re-watched your last video yesterday. Good timing
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
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.
I swear bro I got an A1 mini 2 days ago and NOW you have an affiliate link for the X1?!?
Super cool project.
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. 😉
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
I think belt drives that contour more to the dart's round shape, or use 3 or 4 belt drives would work better
Awesome project 👏
Just in case it randomly sparks enough interest for you to go back to the project, I’ll ask again 😅
Really hope you go back to your robot arm project (even though this project is very much impressive)
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
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.
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.
@@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.
@@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.
@@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.
a spring loaded tension wheel for your belts may be in order
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.
I did replace them with jst connectors, but a non locking variant
amazing that u didn’t give up given all the annoying little hiccups 🔥🔥
very cool project
You had me at Ludicrous speed
Think you can just design the mechanism alone? I think such a nerf gun deserves it's own proper shell, and that means shell integration
Over-integration is usually my downfall. I tried to keep things modular here so the shell is fully cosmetic
Yes!! You're back!
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).
you should make a cinematic for this gun to show it off!
Man i really hope this guy isn't my uncle and going to show up to the family annual nerf gun fight.
It's BEAUTIFUL. Looking forward to whatever you're cooking up next.
It involves irresponsible amounts of current running through tiny pcb traces :)
You’re using a Bamboo printer?! What about the Eclipse3D2?? 😂 I still have mine and it works fine.
Design the gun so it can hold 100 darts or more.. that way, it can actually fire 100 darts in a second
Some seriously impressive stuff, I would love to put together a project half as intricate as this
12:23 DA Torque! 😲
It’s a 2kW motor :) absolutely overkill
this is the exact kind of bulky design and crazy concept for a weapon id expect to pickup in fallout 4. well done
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
Setting it to 10 or 20 darts/s fire rate is actually surprisingly useful! Though a little unweildy for actual use :)
Nice job!
To prevent tumble make a rifled barrel, maybe also a longer barrel
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.
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.
Ah no I haven’t but that does sound like it would help!
great work, most people would have given up after so long
Awesome build
Based dedication to making it easy to skip sponsored sections 👍
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
Use a longer barrel with threads on the inside to guide the darts like with real guns
I'll probably try do develope an autospringer for full lenght darts.
Wonder if someone would want to helf with electronics?
Bro, last time i watch this series i was at a south korean airport, then i just randomly thought of this series again and was blessed
The algorithm knows 👀
@@3DprintedLife 🔥
Great stuff!!
You have the quick firing, but what about the quick loading?
thats crazy! I mean the fact that nerf is not sponsoring those darts 😅
It’s nerf or nothing, and I got nothing!
Amazing. You should make a running minigun. Instead of rotating magazines make it a rotating barrel ;-;
I mean the MOAB by Gatling Tommy is already that made manifest.
It now needs drip and random bits
ive been waiting for this!!!
Looks awesome! Hope you patent the design and then contact Nerf to license your design. 😎
Hah this is maybe a little too dangerous for kids to use...a 2kW motor spinning the massive mag at 11 revolutions/sec could definitely cause some damage!
The way I audibly went "aaawwww" @ 12:13 :(
12:00 the mighty brrrrrrt
You could add rifling to the barrel as well as the stage that rotates it.
Cool flamenwafer
instead of calling the semi-auto mode SNGL i'd suggest SEMI, it's easier to tell what it means
Hah yeah that’s a good point
What if you use suction for loading the ammo fast? 🤔
I wonder if compressed air rather than belts would work better
Probably but that's kinda cheating. I wanted a mechanical solution
Man a Video that even I with my attention span Problem can watch
What 3D CAD software are you using? I’d like to make my own projects but i don’t think TinkerCad is going to cut it.
Onshape! It’s web based, free for individuals, and very powerful!
@@3DprintedLife Thanks!
question esspecially with removable and swappable barrels
rifled barrles what would that be like in this situation
You can but it would slow the darts down. I think some nerf blasters use barrels with bearings integrated at an angle to effectively do the same thing
No full auto in the building!
mfw bro pulls up to the nerf war with a 6,000 RPM nerf gun
That is awesome! Whats the significance of AA-81? Your first/last name initials and birth year or just random?
Haha well…AA because it sounds like and has the fire rate of anti aircraft guns and 81 because my smooth brain forgot the mag holds 72 darts not 81. But 81 had a nicer ring so I stuck with it
dual stage flywheels? that could improve it and also adding rifling
Amazing work here. You're dedicated.
i know a certain pink walrus that may want to review this blaster
This is the gun you pull out when you’re little brother is being annoying
Whats that background music, i think i know it from somewhere.
Does your local Walmart sell dart zone shirt darts?
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
Hopefully you will come back to this project as it is so entertaining
i was waiting for this video
