The “Ported and Polished 8091” Nixie

The “Ported and Polished” nixie clock represents what I believe to be a very unique way of displaying the beautiful NL-8091 nixie  tube.  I say this because most, if not all,  front view Nixie tube clocks are displayed with a shroud of some sort around the base of the tube.  However, in the Ported and Polished, I have recessed each tube in it's own very large 3"/2” diameter chamfered hole then polished the inner walls of each hole to reflect the changing neon digits. The end result is the tube appears larger than it really is. The overall design idea was again to capture the feeling of days gone by, a la the the Streamline moderne design movement of the 30’s and 40’s.  The electronics are by Jeff Thomas and are the same as used to drive the world famous NixiChron. They have been adapted to drive the larger NL-8091 tube by changing the anode resistors and the MOSFET. The species of wood used is the exotic Bubinga and the faceplate is milled out of a massive piece of 6" X 1-1/2" billet aluminum. The clock measure 22-1/4" in length by 7-1/2" high by 3-1/2" deep and weighs over 25 pounds. It is by far, one of the heaviest monster clocks I've built.

It's a whopper...and I think, a true beauty.
