Single-Transistor 1.5V VHF FM Transmitter
This simple VHF FM transmitter uses a single 2N3904 transistor and operates from just a 1.5V battery. The LC tank circuit (L1, C5, C6) generates the RF carrier in the 88–108 MHz FM band, while the input audio from a smartphone or music player directly frequency-modulates the signal. Its low component count, low power consumption, and compact design make it an excellent project for learning the fundamentals of FM transmission and RF oscillator circuits.

An educational hardware reference diagram for an industrial control system is illustrated in 6989.png. The schematic details wiring connections integrating a Raytek M13 module, a 24V DC PLC, an auto/manual switch, and an 11-pin timer relay alongside a 230V/24V transformer and a thermal overload relay to manage a green three-phase motor and various peripheral terminal outputs.
