This video showcases my custom-built temperature-controlled Dual 12V FAN controller powered by a 6W AC to DC Flyback converter (85-260VAC to 12V DC). The controller chip is DK106. The device uses an ATtiny13 microcontroller to read temperature from a 10K NTC thermistor and dynamically adjust the FAN speed using PWM (Pulse Width Modulation). The coding IDE is Arduino and the PWM frequency is 25KHz. The ferrite core is EE19/8/5.
