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!
This is the coolest k'nex project I have seen in a long time! I know that feeling of "Why did I even start this project". Great job pushing through those challenges, this is truly amazing!
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 just happened to be on my recommended. I've never looked up videos of model rollercoasters, but this brings me back to a train/toy shop we used to go as a kid that had metal rollercoasters like this. Love the engineering you're putting behind it
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.
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
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.
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!!
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.
My hat is off to you, looks incredible! I tried to do one of these a while ago with K’nex but got too distracted 😅 Yours looks way better than mine ever did, I’ll look forward to see where you take this :)
"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
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
Oh I know this trick of the trade already, the middle tube is black. It blends in well with the cross ties on the final clips of the ride, so it's easy to miss.
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.
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
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! 👍
Unfortunately the each coil requires 5 io pins to operate (enable, forward, reverse, sense1, sense2) which would require a big package mcu or a bunch of small ones. This is a good point on grounding, I have a new idea to try after thinking about this more.
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.
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.
Hmmm a yo yo roll orange track could this be knex Copperhead strike. Also little note a copperhead strike inverted top hat is very irritating to get right and also the curve after it into the last loop I've discovered this when replicating the ride on my phone in the ultimate coaster 2 but I can't wait to see how it turns out and thanks for replicating my favorite launch coaster in my home park
I wasn't expecting it to work this well, I planned the project around what I was seeing a the beginning of the video. The 360 watt power supply really changed the game!
Can you give a better description. Like what materials in what positions. So we could me one I understand that it works by using iron cores wrapped on copper in wave shaped lines. I also understand that you need a sensor to detect speed and connect to the permanent magnet in the bitty of the car. I found you explanation confusing because there is no pushing process in a real lsm ride.
You misunderstand what a LSM launch does. The way one works is pretty close to how I describe it in the video. There is typically a pulling and pushing force depending on the position of the car. I accomplish the current switching with a motor driver (h bridge).
@ does it work by grabbing the electric copper and wrap it around a iron core you connect the electrical unit and then it power the copper which powers the iron core to make a magnetic field. This lsm unit is attached to the next unit causing a continuous motion. Unless you’re talking about a LIM which uses electricity to power all the units constantly instead of slowly increasing or decreasing.

YES! ITS THE LSM!!!! you gotta make the launch 2x longer and build top thrill 2 😂

It pains me so much that the sscoasters forum has been down for months
I love when stuff like this shows up in my feed. Amazing project!
@@ArtofEngineering you should post a video
9:06 i would suggest using fuses with a power supply like that
Particularly blade-style automotive fuses are great to put on a small board inline. Trucks run on 24v.

Woa, great job, that's a super smooth launch!
You are definitely pioneering (I think that's a real word) this type of launch system for model coasters
This is awesome!!! Amazing work, sir!

I’d be impressed with just the jojo roll! Amazing job you’ve done what every K’Nex builder has dreamed of!
I'm sorry what????This is actually crazy. Thank you for showing on my fyp
Finally an LSM launch coaster!! Awesome video!

ive been wanting to try this for so long. thanks for posting your experience

Yes I suspect that's the problem, I have a lead on where that might be. Hopefully I can give an update in the next video.
My hat is off to you, looks incredible! I tried to do one of these a while ago with K’nex but got too distracted 😅 Yours looks way better than mine ever did, I’ll look forward to see where you take this :)
A multi launch Knex coaster using LSM's is mental. The days of rubber band launches are soon to be behind us
AWESOME!!! can't wait for more videos!
When you emptied the bag of Pico's... well I did something similar recently. That really made me chuckle
If this is a knex recreation, that's 1000% Copperhead Strike. I recognize that first few elements from a mile away.
VEEEEEEERY impressive, great work!
"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."

congrats on the roller coaster!
That works perfectly!

@@michawl_ Oh thats it well done on the first ever knex LSM launch!
cant wait to see the next stage!
this is an amazing video i love this nerdy stuff
Hey cool project! Gotta say your design works quite a bit better than my attempt :D
This is amazing to see working (ps. saw you were at 999 subs, so I subbed 😉 onwards to 10k!)
im convinced to subscribe 👍
A loop and a twist? Sounds like corkscrew from valleyfair

Amazing, irl minecraft powered rail!

:D this is so cool, I want to make one now
Try star grounding. Also would recommend to simplify the control system to only one processor.
Unfortunately the each coil requires 5 io pins to operate (enable, forward, reverse, sense1, sense2) which would require a big package mcu or a bunch of small ones. This is a good point on grounding, I have a new idea to try after thinking about this more.
Remake Velocicoaster!
I get the feeling I should go watch the Siren’s Curse video
magnets are awesome
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.
Why don't you have more subscribers!!!
I need a tutorial for the magnets. I have been failing at making an lsm launch for MONTHS
You could try making a magnetic conveyor belt similar to the Zierer Discovery Launch coaster setup
Thats rad! what are you using to control the coils?
A raspberry pi pico and a motor driver
@@michawl_ Thanks!
Please make an modular Set dor knex maker and Finish your copperhead Strike. I finally found an lsm knex built
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.
have you ever considered using fuses on the output side of the PSU? Would be a good safety net for you
That's crazy

its finally been done
Fun fact. The LSM’s you made for this scale model are more powerful and launch the cars faster than the actual ride. 😂
I wasn't expecting it to work this well, I planned the project around what I was seeing a the beginning of the video. The 360 watt power supply really changed the game!
What do you enjoy more, building the layout or programming and creating the operating system?
The programming/modeling/printing/electronics is what I enjoy doing. The roller coasters are great projects to focus those skills on to.
Stealth at Thorpe Park says hello
It's basically a rail gun setup
this reminds me of prof eric laithwaits magnetic river
flight of fear recreation when
liquid nitrogen the magnets for quantum locking
Copperhead strike
swing launch?
Wait!
Isn't picos powered from 3.3v?
I'm using a daughter board that breaks out the io more conveniently. It accepts 6.5-12v
@michawl_ oh ,ok
Next one you wire. Pre label the wires.
