LED Opto-electronics

As for the reason, the circuit to make is because it makes only once.
Generally, I don't make many sheet of the printed boards with the same pattern.
Also, when changing the circuit after the operation confirmation of the circuit, the universal circuit board is convenient.

However, when trying to make all electronic circuitses with the universal circuit board, there is a limit.
The case where had better make the Printed Circuit Board is
