Launched K'Nex Rollercoaster

Thu Dec 06, 2018 7:29 am

Just came across this fantastic creation. Someone has adapted a K'Nex rollercoaster to make it multi-launch.



From the Reddit thread:

The trains have magnets underneath them which trigger reed switches in the track, which signal the program in the microcontroller to move on to the next step. I try and upload the code in the morning because it's late here in the UK.

The motors are third party and aren't Knex pieces in a u way shape or form. They take 24v and draw about 2.6A (all the power pack can provide). I can't remember the rpm or torque provided, but its very good. I'll dig up the data sheets in the morning.


Looks amazing! :)

They are a nightmare to build, and even then they don't work!

I just remember the blisters from making the original one. 8 hours and it was nearly the length of the room.

But yep, did require frequent adjustments to the cars to stop it derailing.

I used to have a good collection of serpent screamer Rollercoater K'nex, I build some layouts, but sold all mine to purchase the Faller fairground model kits.

There are some great K'nex coaster video builds on Youtube
