What is a Dekatron spinner?
A Dekatron spinner displays a spinning dot by using a vintage "Dekatron" style glow-transfer counting tube.
The colour of the dot depends to the gas the tube is filled.
Neon filled tubes display a red-orange dot (like the one here in this auction).
Argon filled tubes display a purple dot.
The spinning frequency depends to the mains voltage the spinner is connected to and to the counting steps of the Dekatron.
If the spinner is connected 50Hz and the Dekatron is a 10-way counter (like the one here in this auction) the dot spins with 5 turns per second.
If the spinner is connected to 60Hz the dot spins with 6 turns per second.

You can find more information about Dekatrons here at my Dekatron page.

On my page you'll find the complete description of the module, also Nixie tubes and other stuff. Check it out!
This module is good as power indicator for tube amps or something.
You also can build it into a housing and just use it as an art-object

The circuit works with:
 90-130VAC/50-60Hz
or
200-250VAC/50-60Hz

So it will work all over the world!

The following pictures show the tube spinning.
Of course, only one of the cathodes is glowing, but the opening time of the camera leads to that different pictures:

a middle opening time of the camera:

a short opening time of the camera:

a long opening time of the camera:

by night, with  long opening time of the camera:

Here you see a  picture of the module with the tube:

The bottom side of the board:

The tube is mounted in pin receptacles, so it's no problem to replace it:
