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.
