I would be interested in this as well. Are you planning to market and
sell these modules?

Hi Dylan,
It is actually a small circuit board that I have manufactured together
with the nixie watch circuit boards to save costs. The circuit board
is the size of a DIP24 chip and has an SMD 4514 multiplexer that
drives 10 high voltage SMD mosfets. There is 1 spare mosfet on the
board that is not driven by the multiplexer, it can be used to drive
the colon lamps for example, not really a dedicated purpose but I had
board space left over :-). It's pretty basic really, but very
convenient to use.

I'm very interested in hearing more about this module...Are you saying you
are having this custom manufactured? If so, how have you found a way to do
this economically?

For my clock I am designing a module as I am not really a fan to use
these types of old TTL logic. It's a 24 pin module that fits into a
DIP24 IC socket. It basically mimics the 74141 but has high voltage
output mosfets (240V) and the 4 inputs can be latched, so you don't
need extra latches as required by the standard 74141. It also offers a
blanking input, either by writing 0x0a or using a dedicated pin (which
is convenient for PWM dimming). It can be interfaced with MCU or
arduino.
