how much electricitu did you generate in the day?

“I made a nerf shotgun”

V2 update please! Please optimize for actual max watt output 🙏 Subscribed! ❤

結局は失敗するんだよね。マツダのロータリーも駄目だもんね。

is part 2 up?

are you gonna make a coaster with this?

Man it's been one of the most satisfying videos I've seen this year!... let us know if there is a second part 💪👌

This is my kind of optimization. Accessible to more, with less $.

I'm a bit confused by your math for these two videos. When you were adjusting the speed from 25 darts per second it certainly wasn't an accurate fire rate. You would fire 1500 darts per minute at that rate. 100 darts per second would be absurdly fast. Does the mag even hold 100 darts? 6000 rounds per minute is unnecessarily absurd. Would there even be enough space between darts in the air? I don't understand how you're measuring this. 100 darts per second means 100 darts will have been fired by the time one second has elapsed. There's no other reasonable interpretation of "darts per second" I can think of. What am I missing?

how is the plastic fixed to the brass tube?

What is the gear speed ratio?

Brings back CIWS memories 😂

that was such a cool build. Subbed!

@3DprintedLife maybe u should make a nerf tommy gun out of this. this sir really good! they way it looks is like a tommy gun

hi, The spools, what is the mm³ of these coils and amount of windings? max voltage and amps??

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.

Time to add a plc system and swing launch

Great job man. Any plans to reduce the jerks in the motion?

Try use resin 3d printer its smoother

This is a pretty sweet project, modified railgun projects are so awesome. If you do another video on this it would be cool to do a more typical railgun that way the whole track could be powered, but I know that would be difficult to implement

Am I the only one who thought he made a rotary engine watch from the thumbnail?

Hopefully you still get notifications on this; have you made any improvements on your card shuffler, I think a simplified version maybe even a bit more compact it could be really useful for home card games. We still play a lot of uno and I always thought that the cheep alternating shufflers are just not good enough where real randomized shuffling would be so much better but anything that currently accomplishes that are way too expensive for “home” play.

1:15 Why is that tooth brush so jiggly?

Now I know why magnetic levitators are so expensive and why I should not bother trying to make my own! You saved me hours of my life, so thanks.

Can I get the gerbers for the motherboard?

OnShaper- simple wonderful!

While this is cool, the coolest model coaster on yt has drive motors that mimic the motion of a full scale coaster.

I did actually come just to see how a shuffle machine works lol. I work in a casino and so while those machines are different, this gave me the general idea :D.

How about using a propeller governor device to control the pitch and keep RPM constant?

i'd love a full series! cool project and great work!

Very nice. I can't help but think there must be something fundamentally wrong with the wheels though - probably the bearings as you mention - it kinda looks like they're gripping the track.

Just hook up a microwave transformer lol

This is incredible, a series of mini coasters would be great to see

nice

what name the application ?

Dude that is so cool. I'm working on mini LSMs for my model roller coaster as well, and some of your ideas I've never thought of. the PCB coils are super cool.

it always perplexed me how when you get a great hand at casino the dealer somehow gets the better hand. Happens too often and I always suspected the auto shuffler set the cards, now im convinced they cheat us. Thank you your hard work on this project.

Awesome project!

In the early days, the Lego guys were reluctant to visit the theme park.

It is a super cool project and I hope you will continue it! If I wasn't already subscribed, I'd consider doing it just to watch the follow-up :)

What Ratchet & Clank Future song are you using at 0:51 and 3:37 ?

interesting, I was thinking about building a miniature version of the Tykrupp Multi elevator. It uses linear motor to operate and can go sideway. Could be another uses for your pcb coil :p

Man this is so cool! I am inspired to copy you and try something on my own

Fuck it [un-circles your motor]

I don't think all 6 wheels should be. touching the track at once. You need a tiny gap so that 4 at most are ever touching. Ceramic bearings would help a ton too. They don't need to be clamped, just rigid. gravity always keeps a set of wheels touching the rail.

I'd love to see more of this!

The lights are the most important part! They add +10% speed!

Pls more Videos of the roller coaster!!!!
