  • This must be using a voice coil, correct? If so, I'm curious what you used to control the frequency. Thanks!

  • @JeffEmbracedDC We used a solenoid powered through a power transistor. In this video we just used a function generator to send a square wave to the power transistor. I have another video up where we used a microcontroller to send a PWM signal to the transistor, allowing us to control the striking force.
