In this video, I fulfill my lifelong ambition to become a rollercoaster designer. I recreate real coaster tech at a smaller scale, and surprisingly it works quite well! If you want to see me improve and expand on this concept even further, let me know in the comments! LSM Coasters are awesome :D

[@Eutrofication]

oh I'd absolutely watch a whole series of these mini roller coaster videos

[@thiru85]

LED's were a nice touch! Also loved the PCB manufacturing + the build process. Thanks for some awesome work!

[@tuc0w]

This is really awesome! I am thinking about building a 1:87 scale "Wilde Maus" and seeing your wheel assembly helped me a lot, thank you!

[@legoandrollercoasters]

Very cool! You could probably detect the position of a train with infrared lights and receivers (or LEDs and LDRs or similar) and adding another set of magnets to the last car means you effectively increase the launch track by the length of the train. Really hope to see a part 2!!

[@j.1668]

That is wonderful and I'm super interested in seeing more. I loved seeing the wheel bearing design stuff. You say you made it too complicated but I love seeing it :)

[@nbrpwng]

that's super cool, I love to see more linear electric motors from makers

[@SpacemanFPV1]

pls do more of this this is so so cool!

[@nrdesign1991]

Key to a good linear motor is position tracking and field regulation. Some form of low-latency feedback instead of assumption by physical modeling of the train during acceleration could improve its performance greatly.

[@LachsFloete]

That's awesome! Nice work.

[@PC_YouTube_Channel]

3:00 Project Farm reference! truly a man of culture

[@Jademalo]

I don't think I've ever seen a video more to my interests, lol

[@msl2796]

This is sick

[@kanuki0]

finally a new 3dpl video

[@AnthonyDeChiaro]

What an awesome project! I'd love to see a follow-up. I'm also wondering if a thicker copper on the PCB would reduce the resistance. Any chance you could share the 3D and KiCad files?

[@SpacemanFPV1]

Really cool

[@DAustinHorowitz]

I feel like @ryantheridemechanic needs to weigh in on the restraint failures at 0:05... 🤣 Nice job!

[@dwang085]

You are a smart dude. And hard working. That’s a lot of cool stuff you did. Thanks for making such a great video❤❤🎉🎉😊

[@aleksjenner677]

The king is back! nice build

[@macho512]

Would be so cool if you were to make a desk version of the "shuttle loop" from the OG Roller coaster Tycoon

[@3DprintedLife]

Now that is definitely achievable!

[@emanggitulah4319]

Super cool project. Have you tried Teflon as a low friction glide material?

[@icheered]

Epic!

[@_spartan11796]

Very cool

[@uwuanims]

Nice, I got it

[@JonneBackhaus]

Man i would buy this as a kit... hope you will start selling it

[@3DprintedLife]

It was and still is a consideration…but would need a lot of optimizations first

[@frogsshadow4189]

​@@3DprintedLife Could do a kind of preproduction run with the intent to have others test and mess around with the design to help figure out different ways to optimize it

[@theabhominal8131]

hella cool.....

[@rizalardiansyah4486]

Feels like a railgun launcher would have been better but hey! Good work is still a good work!

[@3DprintedLife]

Better performance yes, reliability no. The goal here was accurately recreating roller coaster tech tho so railguns are definitely out of the question haha!

[@damncat2793]

1:08 ...or use an already existing plugin for it?

[@philthy5690]

You watch Project Farm, don't you? 😂

[@3DprintedLife]

Eyyy glad someone got the reference!

[@gedaliakoehler6992]

Nice project! My important question is what kind of iced coffee was that?

[@3DprintedLife]

Asking the real questions. Salted caramel iced latte 😋

[@gedaliakoehler6992]

[@maker3d385]

I can't be the only one who instantly heard the KSP orbit music near the start right?? (Is this just some royalty free track?)

[@3DprintedLife]

Good catch ksp is great. Yeah it is royalty free music lol, frost waltz

[@abdulwaheedouabihi5903]

would it work if you were to put the coils on the train and magnets along the track?

[@3DprintedLife]

Yes you can! That does make controls a lot simpler but the problem then becomes getting that much power to the trains. Batteries add unnecessary moving mass and you’d have to still charge them somehow. Brushes would work but that impacts reliability and adds maintenance. Also it’s a lot of power to pass through brushes! This is all a big reason why rollercoasters have the coils on the track like this.

[@abdulwaheedouabihi5903]

@@3DprintedLife and I just remembered that each coil can only be powered so long before it overheats so having a few coils that are constantly working won't work

your unnecesarily nice comment
