  3. More of Theremin’s contributions • The Terpsitone • The Rhythmicon • Electronic Cello • Silent Alarms • Mad Scientist?

  4. Video Killed the Theremin Star • Spellbound (1945) • The Lost Weekend (1945) • The Day The Earth Stood Still (1951) • The Delicate Delinquent (1956) • It Came From Outer Space (1953) “I just wanted to be a serious musician and play Bach.” - Clara Rockmore

  10. Phototransistors

  11. Inner Workings of Phototransistors • Light enters the base region of the Phototransistor where hole electron pairs can be generated. • Mainly occurs in the reverse biased base-collector Junction. • The hole-electron pairs move under the influence of the electric field and provide the base current, causing electrons to be injected into the emitter

  12. Pin 1: Ground Pin 2: On and Off Pin 3: Current Out Pin 4: Stop, Interrupts Cycle Pin 8: Power Pin 7: Switch to Ground Pin 6: Measure Voltage Pin 5: Voltage Reference
