I was still struggling to choose my arduino project but finally picked one. I want to try relatively easy project since this is the first time I am playing with arduino. So I just decided I will stick to the first idea – the nixie tube clock with arduino. However, I realize that actually there is no interactive work in this project. So I am thinking to put some sensors with the clock, for example, arduino nixie tube clock with a light sensor and switch so it only works when it is dark or user push (or touch) switch.
In tinkerkit.com/modules, It can be useful for my project :
Button, light sensor, and touch sensor.
That interview you posted had a lot of good information. Thanks for that!
