Stinger V2: Pushing The Limits of Brushless Nerf

[@derkaiser9881]

I'm a senior electrical engineering student. This video was absolutely fantastic. That breakdown of why you'd prefer an H-bridge over a flyback diode was sweet.

[@phylippusvonhohenheim3232]

awesome, an genius idea

[@NoHope_]

your production quality seems really good, would just suggest turning the mic gain down, to reduce the peaking, or optionally recording 32bit float which will drastically increase file size but allow you to adjust the audio in post, if not already.

[@Walnut3D]

good tips!

[@bitsRboolean]

Thank you! The youtuber "I'm using a lapel mic in a way other than intended" aesthetic really only works if you can hear them

[@NoHope_]

@@bitsRboolean i mean he can definitely use it that way, and many people do with good audio. Even when it is clipped to his shirt its arguable worse because its closer to his mouth.

[@vecchiofez5560]

I honestly thought this was a 500k+ channel, great quality man! You've gained a subscriber

[@littlemanjonjon]

Boring? That was the most amazing electrical design Ive seen. I am so impressed you put this much work and thought into it. 🤩

[@CrashTestRC1]

Awesome! Please sell hardware kits. I can ‘t afford to pay someone to print And build my blaster for me, so I need to do It myself.

[@CoolerCarl2]

Please do that!!!

[@blendervendor2220]

This

[@richfromtang]

Yes please!

[@salutbonjour123]

This!

[@Mr.Schneeebly]

This would be amazing. And enjoyable for us tinkerers, there’s a bit of satisfaction you get from putting it together yourself!

[@ncc28983A]

I love the explanations and the quick diagrams about each component in the build process. I think this really helps the foam flinging community with design and innovation. Thanks for especially sharing your thoughts about the flywheels.

[@beerdygeek]

3 shot burst mode would be killer.

[@semibreve]

bro why is this guy's filming locations all so interesting

[@TheLootGoblinOfficial]

good work! glad im in on the ground floor of your spectacular youtuber career

[@aaronvandegrift6478]

This video was incredible, the amount of thought you put into this project and your ability to create something so complex and well integrated is worthy a lot more recognition than you have received so far. this is super cool bro, please keep making stuff!

[@Cliffdivefpv]

Super cool project I love how I knew what you were talking about with the brushless motors and ESCs from building FPV drones. I admire you finding the time for a big project like this

[@igorcoene5126]

Damm the guy who made that logo has some great talent!

[@skimboards4life]

I do not care about nerf at all - but I'm here to see the engineering involved, this is an awesome build. Subscribed.

[@Bbeaucha88]

Holy heck. This has got to be the best video quality vs subscriber count I have ever seen!

[@MatterMage]

I'm only a minute in and I'm blown away that you only have 446 subs.

[@lucdaggers6224]

Tripled since you posted this

[@Evil_Duckie]

Thai is the coolest blaster I have ever seen in my life 🤯

[@ilmangiamandragole7857]

This video is so well put together for being a small channel, wow. (i feel like the mic is a bit too high and the mic quality it's kinda harsh) Keep on going man, this is fire

[@builderbb8767]

I love the rear rail option. Great design improvements all around. I've got an FDL3 and Pewtech would definitely add a Stinger to the arsenal

[@Roobotics]

There's an interesting discussion to be had about kinetic flywheel weights. I think it's easy to say lighter is faster recovery so better.. but heavier technically means there is also less deceleration effect as it grabs and transfers it's stored power into the dart. So there is probably an optimal balance point.

[@stingernerf]

I get what you mean but have a look at the graph where you see the dips in RPM. It barely loses any RPM.

[@vornamenachname8001]

the recovery time does not* depend on the flywheel weight, but the startup time from 0 rpm is better with the lighter wheel. a heavier wheel would be good to use if the blaster could not recover the rpm between the shots.

[@jasonrouse8215]

@stingernerf This is where we start looking at Mega darts and bigger/ heavier flywheels with adequate motors... you have the potential to make a "NERF Tank" at this point. Or the NERF Howitzer, sounds pretty dope too, and will probs just be a scaling issue more than anything else. Further Modularity might also favour a "heavier" flywheel in favour of being able to handle any loadout, like for example the Mega Darts or even Elite Balls. You've seem to have reached the point where the only way to improve the product, is to just make it more versatile, or make a bigger/ meaner version. Well done.

[@ReedBigham04]

Amazing vid! Some serious engineering going on here. Keep up the great work!

[@faked8586]

I bet that solenoid makes it feel so good to fire

[@the3rdperson2]

Solid video as always. Appreciate the detailed explanations

[@joeeeyyyyyy]

fantastic video man. twi things i would love to see: It would be so cool to have a blowback kinda like a gas blowback co2 airsoft. maybe also a slide that allows you to manually push the dart into the flywheels, or to open the chamber to manually clear jams! thanks again for the hard work - love it

[@iDoPew]

Oh boy! Closed loop motor control🤤👌 Glad to see you're updating that project further 🤩

[@anthonylipke7754]

I'm weird I like the technical solutions.

[@daveed1297]

Wow. I remember when I thought it was cool to add springs, o rings, and remove air restrictors on the Nerf Longshot back in 2009ish. Long way we've come. This is incredible!

[@Benetheburrito]

Great work Its clear that a lot of thought was put into the design

[@granttoye5852]

I've been looking for a super slim and super effective sub blaster to complement a great loadout idea i have! This thing just solved all those problems for me! In flying colors! About as good as the pewpew, in a maxim form factor, at practically half the size of the maxim!

[@JD-FPV]

not boring at all, loved all the explanation!

[@AScroobs]

You can get rid of the BCAR by putting the flywheels slightly off axis to the path of the dart. I don’t know how well it works with a double flywheel setup, or with concave flywheels, but it’s something that could be looked at.

[@Idontevenwanachannel]

That would significantly increase flywheel mechanism complexity and definitely increase overall width; it's not worth it.

[@PlanetMynd]

Thank you for this offering. Important note (particularly for us U.S. foam flingers)- it’s a blaster, never a gun. A gun refers to a tool that shoots projectiles using an explosive device (igniting gunpowder). Blasters use air and mechanical work to shoot darts/projectiles.

[@CrashTestRC1]

Actually, from someone who is also familiar with the firearm community, I hear people refer to there firearms as blasters, just as much as people in the nerf community. There is no difference between the two.

[@Komfortonset]

I worked on a nerf commercial and we had a saftey meeting that was proactively condemning any use of the word “gun.” Blaster was the only way to refer to the product we were shooting.

[@ILoveTinfoilHats]

​@@CrashTestRC1 that's called "being wrong"

[@nosuma6418]

In theory this is a Gun. Because a gun is any device that propels a projectile through a barrel. Its called a firearm if the propulsion force is generated by burning a substance to create expanding gas.

[@CrashTestRC1]

This is just Because the left has been trying to paint a negative picture about firearms, and guns in general. Like I said, firearm enthusiast call their guns “blasters” to. And their guns actually have an explosive blast, unlike our nerf guns.

[@Shahzad-Khan]

For the PCB you could mount it similarly to how gasket mount keyboards are. Two rubber washers affixed to each side of the board could mitigate extended vibrations from the solenoid. Awesome stuff!

[@KevinLarsson42]

cool project, also great job with the video structure

[@phylippusvonhohenheim3232]

Eu sou brasileiro e acompanho seu projeto desde a outra versão, adorei os detalhes sobre a solenóide e a solução ue você encontrou para descarregá-la , aquilo foi realmente genial.

[@Timbit901]

Really awesome design, honestly designed a lot better than other offerings I've seen and with MUCH more transparency. I'm trying to design a brushless rival flywheeler to use the magnus effect to curve rounds around corners, so if you have any advice I would really appreciate it!

[@shykj8892]

Cool concept! Watching with great interest.

[@chrisbellson7164]

Just found your channel, this thing is sick!!!!

[@crazycatfury2355]

Wingman aesthetics when? 🔥

[@tenguface1257]

So BCAR functions to nerf darts as a rifled barrel does to bullets? Very cool!

[@tmplblck]

This is literally more complicated than a modern semiauto pistol.

[@MidnightMaker]

This totally needs to be incorporated into an Alien pulse rifle...

[@segment932]

Cool. Now we just need a fast magazine swamping belt.

[@Flygonial]

Excellently produced, no surprises here. Though it's not the primary intent, there's enough information here to actually sort of give an accessible look into flywheeler physics and control that's easy to show to an outsider. What capacity does the 6S you used or maybe designed around happen to be?

[@stingernerf]

It's a 550mah pack from either Ovonic or Gaoneng

[@Flygonial]

@stingernerf That's actually approaching or exceeding the efficiency on a lot of singled-staged brushed motor blasters. That says a lot about the potential of 6S.

[@luceedfpv]

As an fpv quad pilot i’m super impressed and in love with the design using same motors and esc as we do in drones. Amazing design. Just for my interest - how much is one piece if you’d make a list open again?

[@luceedfpv]

Moreover if you’d like to do DIY kits and sell it worldwide - very good idea would be recording shorts with designing, assembling and using them in the filed. Like omg this blaster is so cool 😊

[@VEUXTV-VLX11]

You could angle the Flywheels to have the Effect of a BCAR and have a bit Higher FPS because you dont need a BCAR.

[@soza.pidgeon]

Am I the only one who sees the guy at 12:58? Poor dude got trapped between a camera and a blaster

[@malonejohnson3356]

You should upgrade the trigger to a paintball style trigger that you can feather 2 fingers back and forth or hold down for full auto

[@terence79chan]

Awesome work! You have a new subscriber👍

[@OuroborosArmory]

Do you have plans, or a parts kit for sale?

[@JackOHaraEngineering]

So glad you don’t pull punches with terminology and just talk about it like an engineer. Genuinely thought all escs were write only but I buy that alibaba 4 pack for $3 type esc lol Edit: is there any merit in attempting to spin the dart like a conventional bullet or is the juice not worth the squeeze

[@MyFirstYoutubeHandle]

Could you put a rifled barrel on the end to spin the darts on release?

[@minishrimp3009]

Are you going to release the files in some way? Would love to build on for myself

[@betterbuttersticks5073]

Make an over engineered extended mag

[@joox7364]

fantastic video, subscribed!

[@BrainHurts5446]

Would it be possible to generate the spin from the 4 drone motors themselves with adjustments to their angles.

[@nobodyinnoutdoors]

3:46 looks like a shed I saw in a park in Croatia lol

[@SergH.]

Best of luck

[@Obithereal]

Nice. Do you release the files for it or how can i get my hands on it?

[@aronjaeger]

can you please share the stl files ? i want to build one myself

[@ml.2770]

Damn impressed.

[@ivorjawa]

12:55 the electrical engineering is the fun part. Shooting is anticlimactic.

[@anthodaigle]

Pleaaase sell digital files of this! This has a lot of potential for a community to form and make accessories, adjust to local hardware, upgrades... My advice would be to be on a 3d printed website with a community where you can sell digital files, and a Patreon to get early updates & Wips. Also! be careful of not mentioning a brand or patented items (darts) if you are going to sell in larger quantities! I would love that tho! This with premium parts like Carbon Nylon and CNC parts from suppliers like PCBWay would be beautiful!

[@spr00sem00se]

when will we be able to start buying kits to make these?

[@Henri-z4j]

what does it cost?

[@h81_sdnc]

About 700 Euros

[@Heron54]

what if u make a built in tracer unit

[@Zav.-dp9rf]

You could tape the outside of the darts to improve life of them

[@helidrones]

Is there a link to the source code, especially the close loop control for the RPM? Are you using bidirectional DSHOT, serial ESC telemetry or did you bake the RPM governor into the ESC?

[@stingernerf]

we're using bidirectional (extended) dshot on an RP2040

[@maximusdarja]

Why did you not put a slightly smaller battery in the magazine, so they could be recharged independently of the blaster?

[@ikew3150]

Here is this awesome thing that basically nobody will be able to own! :(

[@MaxHill1]

really cool product, are the files and parts out for us to print?

[@ninomusician]

Where can i buy this

[@henrysodey843]

Bro that music is FIRE!! What songs do you use?

[@vornamenachname8001]

why not progressively angle the flywheels from stage to stage to spin the darts? this could distribute the rotational acceleration and remove a lot of parts

[@soundbraecker3642]

impressive

[@Elmojomo]

I don't have an IG account, and likely wouldn't be able to get on the list for one anyway, so this is just for curiosity... what's the cost on these?

[@jimbotron8552]

not trying to throw any shade but why use magnets for everything? why not a nice spring?

[@Vousie]

Im just wondering... How much nerf do you play with friends to make you wanna build this?

[@danward8807]

can u please make the magazine curve instead of straight down like a real gun kinda

[@chez-yd9gg]

not even 1k subs is wild

[@FilmRepair]

lets say just for the sake of science i wanted to fire stainless steel ball bearrings

[@shanegibbens]

If your selling fully assembled I'm interested in buying. Good way to wake up my wife lol

[@Acryodite]

No knuckle guard yes ✅

[@VRNC-kn5tf]

Amazing video it's very inspiring as a student majoring in computer engineering. If you don't mind me asking what degree did you graduate with? You seem to have a very good understanding across a lot of engineering fields.

[@stingernerf]

I am still in my bachelor doing Industrial Engineering (EA-ICT)

[@wokencs330]

you boutta blow up

[@kclazygaming8543]

Awesome!

[@Miaumiau3333]

16:28 no full auto in the building!!

[@h81_sdnc]

just noticed the trails left by full auto, really cool

[@xeverdeadx]

you look like if screech and zach had a baby.

[@smika710]

the mumbling in the audio is rough

[@smika710]

12:30

[@CT-ROBOTICS-7057H]

ligit AWESOME

[@jessehunt154]

It sounds like a high end airsoft gun when fired at full rpm

[@cabooey2905]

bro you hsold have a competition against the 200 darts a sec dude

[@JohnnyTsunami_]

I want a kit so I can print my own shell and assemble the electronics!! Pls pls

[@thalitaneres8605]

interesting video!

[@RIckHOltmannertje]

Please offer the designs for sale!

[@graycockerpunch6191]

great video dude but the background music is so loud

[@anteodak2965]

HARDWARE KITS PLEEEEASEE

[@Frank-fh2qn]

R u related to johan sahageborn?

[@hrmny_]

This isn't really closed loop, for that you'd need a rotary encoder reading physical RPM I'm a bit confused why you need a control loop on top of am32, I would have assumed that it will try to reach the target rpm as fast as possible and hold it as best as possible Really nice blaster, but probably going to be too expensive for me

[@Roobotics]

But the 'eRPM' is the true RPM for the flywheels? It's pulled from the magnetic Back-EMF from inside the motors as they spin. The only thing not closed loop about it is it doesn't know how much grab it has on the dart or it's relative speed to the motors.

[@stingernerf]

Yes the point is to both spin up quickly but also matching RPM between motors can greatly increase accuracy. And this also allows the response time to be as short as possible, shooting exactly when motors reach designated RPM

[@igorcoene5126]

I have 500 of these guns , brokie

[@taegibs7798]

Next over do a drum mag for it

[@rileyrc2461]

Here before you blow up. Great video quality and engineering. If in the future you want to make more, hit me up and I can help design a PCB with you for a blaster of some sort. Seems like a fun project.
