Nulling means tuning to the point that the theremin makes no noise when your hand isn't near it. The term comes from the process of finding the zero-beat frequency point - the point where the 2 osciallators on the pitch theremin circuit are perfectly matched in frequency.

When you play the theremin, your hand causes a change in the frequency of one of the oscillators while the other stays fixed. You hear the beat frequency, or the difference between the 2 oscillators.

Hope this helps!

Wow. I keep thinking that someday I will build my own theremin from scratch but I keep reading these posts and it seems like an ordeal to get one up and running.

Of course, all I hear here is the problems so my perspective may be slightly skewed.

The other great theremin website (*waits to be hit for advertising the competition*) has loads of schematics. I'll link you because there might be something that's of use:

Wait. Perhaps this is the actual theremin you were refering to. It's called the 'simple theremin':
