IN-4 Nixie Clock using ATmega168

andrea biffi @ instructables.com has a detailed tutorial on how to build your own Nixie clock using IN-4 tubes and Atmel ATMega168 microcontroller.

Nixies are neon valve tubes, where ten cathodes have shape of digits and are lighted up by plasma when high voltage flows through them. I love these old era displays, which have been employed in last century before I was born.

In last year I’ve been slowly collecting components and knowledge to build some nixie clocks as Max Pierson’s beautiful creation, I like the old style, the roundness of glass tubes, the rough wood case, the simplicity of the design. That clock has definitely inspired my project. Even though I really love vertical digits arrangement I keep that original feature for my next clock.
