Bored. Started a new project. The circuitry unit I am building are the wired chips that interface a timer to a relay board.

The control circuit will receive a selected pulse from the counter and alternate the on off cadence of the two Relay board. This will give me a left/right direction of a motor. With this motion of the motor, I will sweep a angled di transducer left and right at a controlled rate and time. A real sweep sonar.

Maybe it will work. Love tinkering.

Here is a Pic of my prototype.

It works. Waiting on a relay board.
