TDA2009 Ampl BCL (bridge amplifier) 18W ,Supply volt = 23V 2A The TDA2009 be 10 +10W STEREO AMPLIFIER integrated circuits interesting again the one number. We try to bring do the circuit amplifies 18W sizes better or Power Amplifier BCL 18W by IC TDA2009. Be circuit character model 18W Bridge amplifier the sound better model […]
This is a mouse and insects repellent circuit, use high frequency out of the piezo speaker and IC-556 is base as oscillator between 22kHz and 56kHz This projects is safer and more convenient than using chemicals to turn switch on only and use Low power consumption (only 0.5 watt) . How This Circuit works The […]
This circuit uses a 555 IC timer number. This small,compact and portable. For the snooze alarm by buzzer when some 5 to 30 minutes. It makes clear the brain is ready to continue to work. When the switch S1 to enter a power supply circuit, it will be ready to go.The circuit includes a circuit […]
