I believe Scarborough has died. when he was still in this world I communicated with him several times. As I recall, he was a priest or minister of some church in Africa. His hobby was electronics and he came up with some nice but simple designs.

Looks like a simple detector. has anyone built this? The circuit is a standard oscillator using the coil to change frequency when in presence of metals.
