Electronics Comeback

I have (just about) made a comeback to electronics. A major publisher snapped up my magnetometer -- a magnetic field detector -- which likely means publication worldwide. It is no small project. I submitted nearly twenty pages of technical material. OBSERVATION: Behind the scenes, though, this is not a profitable undertaking. The effort and expense were enormous, all the more so because this was an experimental design -- I kept running up against unknowns -- and all the more so because I had had a long absence from electronics. But it's a good one. My sense is that it will go down as a classic.
