The 12-Point Star Coil Pulsed Motor is a brushless, Bedini-style motor demonstrator with copper wire wound in a 12-point star around pillars on a clear acrylic frame. A Hall-effect sensor triggers current pulses to keep the magnet rotor spinning, and DIP switches let you change resistance, add a capacitor and toggle diagnostic LEDs. It is a hands-on electromagnetism demo for under $50.
