Self Balancing Gyroscope on Two Inline Wheels

About: I am an American teaching English at Shangluo University, Shaanxi. I like making machines that do interesting but fairly useless things - I call them Quixotic Machines.

Warning: cd rotors are very dangerous, mine was cracked and exploded. If you must build one, wear safety glasses or you may end up blind.
This video shows how I got a two wheel model to balance using a home made gyroscope from a toy motor and 4 stacked cds for the rotor. There is a little trick to doing this that I talk about in the video. Hope others will make one too and improve on it.

I know this has been done many times before but I couldn't find the details on how to do.

I also tried attaching two parallel wheels but it just wants to spin in a circle and when I try to move it in the direction of the wheels it falls over easily unless I push very slowly. I suppose motorized wheels will work but without some active dynamic balancing mechanism it would be pretty susceptible to falling.

    Thank you! It's always a cool feeling when something you are making actually works.
