This is an update to the previous post: https://www.reddit.com/r/ProjectHailMary/s/VwEyCbzot5

I added 3d printed bricks at the bottom with a bit of cushioning to dampen the sound from the stepper motor and altered the code a little.

To the how I made it-

I used a Pico 2 W with a stepper motor control header

The front is flipped around and all parts for the hand crank are removed.

I used a flat 2x2 3d printed part to hold the motor in place

I used a self-made 3d printed stepper (5mm∅) to Lego technic adapter.

No Lego piece has been glued, cut or in any way modified.

It's currently powered by a servo controlled by a Pico 2 W hosting a website with the most shitty servo driver I was able to get my rat hands on.

Starting and stopping is only handled by the Pico so no remote and speed is controlled by the website too of course.

Still working on making it better with the materials I have on the floor somewhere.
