But the top seems rough, we don't know if this is a real and working motorized top.
The Infini-Top precesses clockwise or counterclockwise ?
The Infini-Top with the full shell and good batteries works very well. As you can see at the end of the video below, it will rise by itself from a laying down position.
It precesses clockwise, like the black internal part that carries most of the weight.
Sorry, I haven't thought that the Infini-Top too is blue, but I was referring to the other blue top, the rough hand-made blue top of the video posted by Jeremy.
I never doubted that the Infini-Top is a functioning and effective motorized top.
The Infini-Top seems to behave quite similarly to a normal spinning top;
the tip is attached to the black chassis, which is the heavier part of the top, so the top walks and precesses in the same direction, (clockwise), like a normal top.
The tip rolls in the correct direction for the rise of the top, like in normal tops.
Vibration seems not necessary in this top.
Then there is a lightweight casing, pushed backwards, (counterclockwise), by the black chassis, through the motor.
The casing, for reaction, gripping on the air, pushes the black chassis clockwise, through the motor. This keeps the top spinning by the time.
It's a bit like a swimmer, who moves backwards his arms into the water, (the light casing into the air), and, for reaction, the body of the swimmer is pushed forward, (the black chassis is pushed clockwise).
If I remember well, you already gave a similar explanation, which I believe it is correct, at least for this motorized top.
The rotational speed remains pretty consistent, at about 1600 RPM clockwise for the black case and 720 RPM counterclockwise for the blue shell.
So the black chassis, through the motor, spins the casing at 2320 RPM.
1600 and 720 RPM are the speeds at which the torques of air drag and tip friction find an equilibrium and have the same magnitude.
But I can't understand yet the toupie lumineuse. Not even having it in my hands. The tip here is part of the casing, so the tip friction can't be used for to push the casing backwards against the air and keep the top spinning.
