Alas; this circuit violates
The Law of Pernicious Parts Count,
which states:

"In any home-brew circuit, every part added
beyond 10 will divide the number who actually
build the circuit by half."

Sad but very true.
There is an exception:  If one has a pre-made
P.C. board for the project, the law does not apply.
