On Finding an Excuse to Buy an Arduino or: How I Finally Got Myself a Theremin

On Pulling Musical Notes Out of Thin Air

I am an unapologetic Downton Abbey fan. The series is full of memorable scenes, but one in particular has stuck with me. Daisy, one of the scullery maids, is asked if she turned on the electric lights in one of the rooms and she replies "No. I daren't".

It seems like such a minor, throwaway line, but I feel like it succinctly captures how the uninitiated must have felt about electricity back then. Daisy is downright afraid of it. Steam and fire are very direct and literal sources of energy, but electricity is much more abstract. You never see the electricity moving or burning, even as the motor spins or the lamp shines.
