How they heck did you comment 4 hours before the video gets posted?
Just wait for my next project…a pocket sized Time Machine 👀
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 😮
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
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
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!
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
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.
Finally, I’ve been waiting so long for the update! So pumped!
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.
When this came up on my feed, I thought it would be using Compressed Air, But this So much more complicated than that Kudos!
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
This is absolutely Amazing! I would love to get my hands on this! Great work!
Maybe you can build a nerf lancer from gears of war with a nerf chainsaw congratulations for the project by the way
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.
@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.
I lol'd at "consumables." Great work!
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. 😉
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.
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
15:05 a dart lands upright lol, its just under the barrel
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 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.
amazing that u didn’t give up given all the annoying little hiccups 🔥🔥
very cool project
Based dedication to making it easy to skip sponsored sections 👍
Awesome job! Absolutely love it and all that hard work BRO… nicely done!!!
I've been waiting for this to drop, looks awesome!!
this is the exact kind of bulky design and crazy concept for a weapon id expect to pickup in fallout 4. well done
Awesome project 👏
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 :)
I swear bro I got an A1 mini 2 days ago and NOW you have an affiliate link for the X1?!?
Super cool project.
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.
instead of calling the semi-auto mode SNGL i'd suggest SEMI, it's easier to tell what it means
I think belt drives that contour more to the dart's round shape, or use 3 or 4 belt drives would work better
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
lol I just re-watched your last video yesterday. Good timing
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
you should make a cinematic for this gun to show it off!
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.
You had me at Ludicrous speed
a spring loaded tension wheel for your belts may be in order
Yes!! You're back!
It's BEAUTIFUL. Looking forward to whatever you're cooking up next.
It involves irresponsible amounts of current running through tiny pcb traces :)
Awesome build
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).
Man i really hope this guy isn't my uncle and going to show up to the family annual nerf gun fight.
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)
You’re using a Bamboo printer?! What about the Eclipse3D2?? 😂 I still have mine and it works fine.
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.
Great stuff!!
I'll probably try do develope an autospringer for full lenght darts.
Wonder if someone would want to helf with electronics?
ive been waiting for this!!!
To prevent tumble make a rifled barrel, maybe also a longer barrel
A) How is Nerf not sponsoring you, and 2) I want one of these so bad 😂
great work, most people would have given up after so long
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!
Design the gun so it can hold 100 darts or more.. that way, it can actually fire 100 darts in a second
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
Use a longer barrel with threads on the inside to guide the darts like with real guns
Is it just me or does this look like a bolter
For the emperor
12:23 DA Torque! 😲
It’s a 2kW motor :) absolutely overkill
thats crazy! I mean the fact that nerf is not sponsoring those darts 😅
It’s nerf or nothing, and I got nothing!
Cool flamenwafer
Hook that thing up to a compressor and you could do it totally mechanically. No electronics required.
It now needs drip and random bits
You have the quick firing, but what about the quick loading?
What if you use suction for loading the ammo fast? 🤔
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 :(
Man a Video that even I with my attention span Problem can watch
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
I wonder if compressed air rather than belts would work better
Probably but that's kinda cheating. I wanted a mechanical solution
mfw bro pulls up to the nerf war with a 6,000 RPM nerf gun
Amazing work here. You're dedicated.
No full auto in the building!
i was waiting for this video
YEAAAAH BABY
Does your local Walmart sell dart zone shirt darts?
i know a certain pink walrus that may want to review this blaster
Can make it shoot the ball darts?
Whats that background music, i think i know it from somewhere.
What's with all the Taylor Swift songs mentions? :D Bad blood, blank space, shake it off?
Whaaaatt
@@3DprintedLifethat’s just down bad
Holy shit he did it, the absolute madlad.
also, it looks so good, reminds me of recent US fighter jets with the paintjob to show exactly where components are, but a bit more polished. Awesome design, awesome execution
also yes, I skipped to the end, whatever
Why does it look like the surge fire?
This needs a dart sensor to stop when jamming
It actually just needs the software. The ODrive I use to control the drum has both torque and position error feedback, so it would be possible to look for a sudden spike and large error and cut the power.
next: 0.9c nerf gun
This is gonna be at Endwar right?
Try hyper boolets.
Are you still making the robotic arm?
It’s on the back burner at the moment, too many other projects
new video lets goooooooooooooooo
Taylor Swift references? 3:25 3:38 3:55
A BCAR or a SCAR might help
this is the nerf a10 warthog gun :)
yay
epic!

Link to the onshape project is in the description. It is a very difficult project so you need to understand the cad model if you want to print the parts, which is why I don't directly provide the stl files.
@@3DprintedLife oh thanks! I wasnt expecting u to reply but its super cool tho
