How About a Nice Game of Chess?
Greeting Professor…
This is cool no matter who you are. A nice chess set with vacuum tubes that apparently light up when they are placed into the sockets on the board. Very nice. However, a close look at the photos, and it appears that LED’s are doing the actual illumination. Well, I guess 20kV of filament voltage would burn the fingers.
This wonderful vacuum tube chess set, by maker Paul Fryer, actually has electricity running inside the board so that the tubes can draw power and glow as you move them from square to square. It is called, somewhat appropriately, Chess Set for Tesla, and Paul actually made seven sets last year.

Important note. The filament voltage of tubes is normally 12.6VAC or 6.3VAC. The reason LED’s were used is because the tubes would be hot enough to burn your fingers when left on.
