This is an electronic kit for the very experienced hobbyist.
The hanging clock shows 1250+ parts in all their
glory.
There are no Integrated Circuits, all functionality is achieved using discrete transistor-diode logic.
The 180 volts for
the NIXIE displays is
developed from 12 volts by a boost switching power supply, which is detailed in the manual.
The assembly manual has
a logic tutorial and circuit descriptions that attempt to explain how the clock works.

The
kit
comes with all parts and the PC board with the part symbols showing
the values of the components for easy assembly. Solder and
solder-wick are included, along with spare
parts for many items.
This kit is for experienced builders only!!
This project generates high voltage to power the nixie
tube display and can be very dangerous to those unfamiliar with safe handling
techniques. Only those experienced with building or working with high voltage power
supplies should attempt to construct it.
If you are not
qualified, we suggest building the original
Transistor Clock instead.
