A multi launch Knex coaster using LSM's is mental. The days of rubber band launches are soon to be behind us

Looks insane dude nobody has even come close to you with this, if I were you to improve heartlining and shaping I'd use middle tubing as it really enhances the effect and looks more realistic

Super cool and Im pretty sure that the flag is mounted backwards like if you're standing facing it the stars should be on your left side

It's basically a rail gun setup

I’d be impressed with just the jojo roll! Amazing job you’ve done what every K’Nex builder has dreamed of!

AWESOME!!! can't wait for more videos!

Finally an LSM launch coaster!! Awesome video!

I like your tinkering with electronics. Your using coils and that is the same as an inductor. The coil has inductance... What does that mean. You apply voltage to the coil, and the current start flowing every millisecond a little more, increasing linearly. What does that mean. A little explanation when your cart go fast. You detect the cart. You apply a voltage to your coil. The coil picking up current and magnetism slowly over time. The cart overshoots a little, you detect that with your sensor. Then you invert the voltage, but the current (and the magnetism) still flows in the other direction slowing the cart down. You have a lot of sensors, so you can calculate position and speed and in your program you can compensate the timing of the voltages applied to the coils. Good luck and a happy new year.

When you emptied the bag of Pico's... well I did something similar recently. That really made me chuckle

After this I dare you to make an lim (linear induction motor)

"Can you guess what I'm building yet?" "I have no idea but it kind of seems a bit like Copperhead Strike (which I just rode for the first time despite living in Charlotte and having been to Carowinds plenty), but nah it's probably something else." And then it actually was Copperhead Strike :0

I love this! Let me know if you have any circuit or electronics questions since I work with this scale of power electronics for my job. I'm particularly interested in making sure you've got good protection for the control circuitry from the power circuitry after seeing several of the picos meet their demise

You're the indoor zna and I love it yes that's a compliment 😂

this reminds me of prof eric laithwaits magnetic river

liquid nitrogen the magnets for quantum locking

Next one you wire. Pre label the wires.

Dude, this is wicked. Came for the LSM, stayed for the K'nex. Is this a standard K-nex rollercoaster system or something else. They have only ever sold the coasters with mini trains here.

im convinced to subscribe 👍

I love these types of projects, and I can totally relate with destroying microcontrollers. Awhile back I build a beanbag catch and throw project with an old laser printer motor that drove a winch and pulled back a huge spring. The whole thing was run from a lead acid UPS battery. When the spring released, it would spin the motor and put some 50v back into the power supply. Even adding a big capacitor across it didn't help. We fried two microcontrollers before we decided to isolate them on a different battery from the motor.

Holy shit! This seems so much cooler than model railways to me! Edit: If changing the power source fixed the issue (and voltages were correct) you likely had a ground loop, at minimum they cause interference at the worst they facilitate magic smoke escapes.

Fun fact. The LSM’s you made for this scale model are more powerful and launch the cars faster than the actual ride. 😂

Amazing, irl minecraft powered rail!

This is amazing. Wish you had shown up in my feed a long time ago!

Always love that slow jojo roll. Amazing stuff so far

swing launch?

cant wait to see the next stage!

Hey cool project! Gotta say your design works quite a bit better than my attempt :D

Fuses exist yk...

Did you make the 3D model for those Gridfinity containers? Where can I find some so I can make my own?

magnets are awesome

I get the feeling I should go watch the Siren’s Curse video

You got to recreate Wicked from Laguna amusement park. because it has a vertical LSM launch, and it is the first roller coaster that has a vertical Sim launch. Usually, you need some kind of way to cool down the coils.

Why don't you have more subscribers!!!

Okay. I just discovered you and i love your content. Please make more of these, i love small project with big technology that you explain simply. That is very cool and i want to see more ^^ Greets from France!!

its finally been done

I’m in Charlotte and I’ve been to Carowinds twice and been on both fury and copperhead strike I was done with roller coasters for the day after that but I feel honoured that you made copperhead strike

A loop and a twist? Sounds like corkscrew from valleyfair

Amazing. Congratulations on making what I have dreamed of. "Spacewarp" by Bandai was released in the 1980's. I loved it. One of the issues I had was with the motorized carriage that returned the ball to the top of the track. I used it so much it slowly wore out the Archimedes Screw return carriage. It would bog down and get stuck if too many balls were in play. Then I did the thing you don't do to plastics. I oiled it with some of my mom's sewing machine oil. I was so sad. The oil caused that plastic to crack and become brittle. Once the return carriage screw started disintegrating, it was game over. Fast forward to today: watching your video has satisfied my childhood dream. You have built what I had imagined was possible and wished I could have "manufactured"! Thank you for making my dreams a reality. Cheers Friend!

This is absolutely incredible. It's been literally decades since some of the folks at SSCoasters were trying to make something like this, and no one even came close to the success that you have shown in this video. Can't wait until the final Copperhead Strike video. Also hoping that this system gets perfected enough that those of us who are less electrically gifted are able to reproduce it!

Stealth at Thorpe Park says hello

I’m currently building (well, it’s been stuck in development hell for some time) Xcelerator but using the CDX Blocks coaster kits plus huge amounts of LEGO. I assumed I would have to use a tyre or chain launch but wondered if an LSM launch was possible. Subscribed and watching with great interest.

Why did he perfectly describe my grades in one sentence: and then go like blblblblbl down

Fantastic work! Definitely subscribed to see how this progresses. Very interested in the control system you plan to build - any chance you'll go over-the-top and use a PLC? Either way... awesome project! 👍

Congrats on ur 1000th subscriber! I have no idea who it would be ;)

This is amazing to see working (ps. saw you were at 999 subs, so I subbed 😉 onwards to 10k!)

VEEEEEEERY impressive, great work!

You could try making a magnetic conveyor belt similar to the Zierer Discovery Launch coaster setup

:D this is so cool, I want to make one now

congrats on the roller coaster!
