Lego Technic Meets Gravitrax: Height Gaining Pendulum
A height gaining pendulum for Gravitrax marble runs built with Lego Technic parts.
My son and I, we love Gravitrax. It's like a system of building bricks for marble runs. And just like with Lego you can add more and more parts to be able to build bigger projects.
But sometimes you really reach limits. The biggest challenge is that for a long run of the marble you need to gain height from time to time. There are extensions to gain height, but with most of them the marble will only gain the height of 3 to 5 "bricks", which is not much.
One solution are "custom" electrical lifts, most of them built with 3D printed parts. A rather simple solution are pendulums activated by a marble on a lower level starting another marble on a higher level. Most of these are also built with 3D printed parts.
But not everyone has a 3D printer at home, but as a "brickhead" I have Lego Technic :-)). So I started looking for solutions to combine Lego with Gravitrax.
Well, it works, so I was able to build this.
