Single digit pyramid Ash wood Nixie clock:
Green or Yellow version available
On the top of the pyramid, a large
New Old Stock socketed Nixie tube (IN-18 Russian tube) display hours and minutes

½ a second with a slight pause between each digit to improve visibility.
This funny non-conventional way
of reading hour will captive the attention of every body and provide a nonstop
digit moving in the tube.

setting the clock; magnetic contacts (Reeds) are used in place. Setting the
clock is done with a small magnet (strong earth type).

top left angle of the pyramid will set hours, top middle front angle for 10's
minutes and top front right angle for minutes.

running when unplug from main.
