I've never ever done anything like it before so right now it all seems like voodoo to me. But if I get this right I would need an arduino board which I must buy separately, and if I look at the arduino site, ArduiNIX works with an earlier revision, not the latest. correct?
I assume that a driver shield is like an add-on board that can be connected to the Arduino board and that is what ArduiNIX is.
Also I don't want to make it too easy for me so I am thinking of buying just the board and installing components myself, or is that too much you think for a noob?
My plan is to make myself an alarm clock, I just haven't found a good alarm clock in stores. Something I saw came close, namely this:

So the idea so far is to buy some cheap twin-bell clock like that and take out the innards and place a nixie clock inside, maybe replace the front glass with smoked glass and have the tubes behind that. Is the arduino and arduinix small enough you think to fit inside such a housing? I think they are usually 7-8 inches in diameter.
