How to Self Balance a Structure or Vehicle with a Gyroscope

Update Oct 2019: Wow, just ran across these two free pdfs by Mori, Hiroshi about how to make self-balancing gyroscopic monotrain. Includes all the theory and practical aspects. A must read: and: My free ebook to help you construct your own vehicle: I present some lessons learned about using a gyroscope to balance a structure or vehicle by constructing a model to demonstrate free precession. I have been able to balance this demonstration model over 15 seconds now before the gyro runs down. UPDATE: just occurred to me that I don’t need the extra weight - as one side of the gyroscope is already heavier than the other so I just spin up the gyro then swivel the heaviest side to the top and it actually balances longer and smoother than if I add weights.
