Z502S (Mullard)
Dekatron counting tube
Bi-directional double-pulse decimal counting tube.
Neon
filled.
The following pictures show the tube spinning.
Of course, only one of the cathodes is glowing, but the shutter speed of the
camera generates different pictures:
A normal shutter speed of the camera:
A high shutter speed of the camera:
A low shutter speed of the camera:
By night, with low shutter speed of the camera:
An animation of a spinning Dekatron:
