Capacitors on the Curve Tracer

by

At its core, a curve tracer generates an I-V (Current-Voltage) curve. It does this by actively varying (sweeping) the voltage applied to a component and simultaneously measuring the precise amount of current that flows through it at each voltage step. Sweeping (2-Terminal Devices): For a simple component like a resistor or a diode, the curve … Read more

Healing with Cymatics Sound Medicine – a deep dive

by
Cymaheal

Healing with Cymatics Sound Medicine – a deep dive Life vibrates. An exploration of cymatics and vibrational healing through three distinct lenses — ancient history and mysticism (e.g., Saqqara and the Voice of God), modern fringe research (e.g., military projects, Emoto, Eileen McKusick), and biophysical mechanisms (e.g., protein formation, vibrational synthesis of life). Each will … Read more
