Robert,

Your email isn't listed, but please send one to my email. I'm about to start building the optical theremin from the oldmtemecula site. I was also hoping to build the RS theremin but haven't gotten the circuit PDF from Christopher. Perhaps he is just on vacation.

The emails should be hidden,
if somehow they are visible please tell me!
User privacy et. al. you know.

But if you really want to share it publicly you can put it in your website field and mark that for display.

As I said, I am happy to share this with anyone who asks. The more people who build it the better. I am hoping that this Theremin may bridge the gap between the Theremax, and the Etherwave. Granted, it is not a kit, but if we all make careful note of parts lists and construction, we can come up with great step-by-step plans.

I did an SMD PCB layout for the pitch oscillator
section of the EM Theremin. I changed the biasing
to run off a +-5V supply and added a small switching supply to the board. I also added a Maxim MAX9770 amplifier IC which is a 1.2W Class D amplifier with a headphone and speaker output.

I have a photo of the populated board at

http://www.luciani.org/eng-notes/ee-notes/ee-notes-index.html

The bottom photo shows the board. Only one of
the four antenna coils can be seen in the
photo.
