Big thanks to Vizonex for discovering the principle behind this fascinating mechanism. Be sure to check his channel / @vizonexbuilds and the original video • Lego Hand of God Shift...
Again, this video is fresh and new, with all the filming and editing being done after the previous video was published. It was planned long before, though, in the meantime I somehow even managed to stumble upon Vizonex in a Discord voice chat and got a permission from him.
Extra info about the mechanism:
- I built the mechanism based on Vizonex’s video, although I modified few things and improvised on the parts that couldn’t be seen
- It’s built from my own parts I had on hand at the time, don’t consider it as building instructions as the structure can be built in many ways and mine is definitely not the best one
- The intent was to best show how the mechanism works, I thought the build process could help with that too (still, you can build it based on the video if you want)
- The combination of knob gears and 5,5 long axles is what makes it work
- The axle pushes the knob gear more than 45 degrees, which is important because when the axle is retracted back, the stepper has to snap to the next position and not the previous one
- Rubber bands are required in 2 places - the stepper part of the stepper, which makes the rotating shaft snap to every 90° position and the levers themselves, which return up automatically
- My placement of the rubber bands is quite janky, I didn’t bother to improve it, of course you can use other rubber bands including Lego’s, although you might need to change their attachment point
- The blue pins on the levers themselves act as an end stop, I added them myself because they improved things in my configuration, though they might not always be needed. I specifically paid attention to their rotation, you can see it in the video
