A second piezoelectric blower driver, built so I could run multiple blowers. I believe the paired blowers were used to push air from opposite sides of a fluid system, moving ferrofluid back and forth during the magnetic-refrigeration experiments.

A driver I built for a piezoelectric blower, a small device that moves air through vibration. The controller supplied an adjustable electrical drive signal for airflow experiments involving small fluid volumes. Keeping water out of the blower was important.
