Week of 3/24/25

This week I continued assembling the design I had made the week prior. The old motor pins I was using snapped off inside the gimbals, which meant I had to 3D print all the gimbal parts again. I had to redesign my motor pins anyways, as the previous ones had no way to connect to the servo motor. Speaking of the servo, I also finalized my design for the mount that attaches the servo motor to the body of the train. Originally, I was planning to go with a two-part 3D printed mount that the servo would slide into, but I eventually gave up on it, as I came up with a new design that uses a single laser-cut piece instead.

I also redesigned the pegs that secure the gyroscope gimbals to the chassis. The previous design was just for testing if the build would work. The new design has an added part that will attach to the servo motor and allow the motor to control the gimbals position.

This is the fully assembled testing rig. Next week I will begin placing the electronics and getting the flywheels ready to go into the gimbal.
