to mark as completed Adding motor to a toy gyroscope
The following video shows a cmg balancing itself on two legs (screws). I took a toy gyroscope, cut the gyro shaft and added a brass adapter between the shaft and a 180 dc motor (5mm to 2mm). Then mounted the motor to the top of the gyro frame and held it on with a single zip tie. Surprisingly it holds the motor on quite well but there are some high frequency vibrations going on.
I have ordered some 2x5mm bearings to allow the gyro shaft to rotate with a little less vibration.
Also need to up the size of the motor as it heats up and will eventually burn out I think and the added weight on the top of the gyro should help fight the precession a bit.
This next video is of a gyro car that I completed in 2021 but had worked on it for six or seven years. It will balance very well, even on a rope. It moves forward and backward with left and right turns. It uses a single gyro like the GyroX car from 1967 and unlike the dual cmg cycle from Lit Motors.
Finally, here is a free booklet I put together on the subject:
