How the Circuit Works (High-Level) This board is not a simple oscillator.
It is a multi-stage gated pulse system.
Signal Flow Overview DC Power ↓ Voltage Regulation (12V / 5V) ↓ Pulse Oscillator (LM3900) ↓ Pulse Shaping & Logic Gating (4011 / 7408) ↓ Monostable Timing (CD4528) ↓ Buffered Inversion (7404 / 7407) ↓ Power Switching (TIP120 → MOSFET) ↓ Inductive Load (LP+ / LP−) 3.
