Big changes to the car project!

The old design began to stop working because the cardboard gears kept wearing down and the stepper motor was a lot slower than I wanted it to be, which is why I decided to switch to 3d printed gears.

With this switch, I also decided to change from using the stepper motor primarily to now using a dc motor.

The first step to making the dc motor usable, was making a gearbox, and the first iteration didn’t go very well… I made it gears first and motor last, which caused the gears to not have enough play and required too much torque from the dc motor. Which is why I had to rebuild it, with right spacing and now it works!

The video should be a short showing of how the gearbox works!
