Interesting Design

I have completed the core design of a detector circuit. It has been (to me) a very interesting design. It lights up when two frequencies un-lock. Both frequencies may be adjusted, both frequencies may shift, and the strength of the lock may be adjusted -- between total lock and a refusal to lock. As an easy first application, it responds to the electric field which surrounds the (living) human body, at a quarter metre. It also (so far) responds to moving shadows. OBSERVATION: Five months ago, I had a magnetometer published in the UK. That was probably the most complex circuit I have ever done -- yet easy to develop. This latest circuit is quite simple -- yet full of unorthodoxy and subtlety.
