Old Photo#1 - Breadboard circuit

Old Photo#1 - Breadboard circuit

As I started my blog, began to run out of Google space.

When I have free time, I am deleting the photos from Google Photos little by little.
Some of the photos that were automatically uploaded unintentionally have memories.

It was a project to analyze two-channel waveform difference.
we had to make some of the whole circuit on the breadboard.

I did not know then, but it looks so beautiful now.
