Nixie Tube Mania - A Speedometer and a Chess Set
things just shouldn't be done, like converting a World War II
era Douglas DC-3 airplane's engine from its original twin multi-cylinder
radials to jet-engine-powered turboprops; it violates nature's rules.
Another example might be installing a
speedometer in a vintage pickup truck. I say 'might' because thanks
to Luke Miller's ingenuity, his 1953 International pickup truck
- indeed the world - now has a proven plan for a GPS-driven, two-digit
speedometer featuring a Nixie tube numerical display. A two-part
article on the EE Times website provides the theory of operation
and the details for constructing the Nixie tube speedometer. Why
GPS-driven, you might ask? It was evidently simpler - and more impressive
- to do so than to tap into the truck's speedometer cable and implement
a sensor. An added benefit is portability. This looks like a Kickstarter
opportunity for commercial productization if there ever was one.

In other Nixie tube news, the
Nixie Chessboard DIY kit is now available for sale just in time
for Christmas! The price is $399, a mere pittance of a sum
when you consider it includes 32 Nixie tubes and all the required
parts, even the 12V power supply. Unfortunately, if you want give
it as a gift, you'll have to wrap a promise for delivery in 2014
because its popularity has caused a stock depletion.
