Simple Audio Booster circuitHere the simple, low bulk and accessible audio booster circuit. It uses a transistor of 2N3392 ad the capital amplifier. This ambit has a maximurn accretion of about 22 dB (voltage gain). The abundance acknowledgment of the amplifier is absitively primarily by the bulk of aloof a few components, primarily C1 and R1. The ethics aural the schematic architecture present

Relay Circuit 9 Second LED Timer
Relay Circuit 9 Second LED TimerThis circuit provides a visual 9 second delay using 10 LEDs before closing a 12 volt relay. When the displace about-face is closed, the 4017 decade adverse will be displace to the 0 calculation which illuminates the LED apprenticed from pin 3. The 555 timer achievement at pin 3 will be aerial and the voltage at pins 6 and 2 of the timer will be a little beneath

Passive Crossover schematic
Crossover is a tool to limit the "frequency range" to be accepted by the speaker. Imagine that the court act as traffic police, which regulates the flow to the tweeter, midrange and bass for the subwoofer. Imagine if you had not crossed, the frequency will be chaos, there is a loss of low frequency on high street frekwesni tweeter on the subwoofer, so it is not effective and also if there are

SCR-DC delay circuit
The apparent reality of circuit diagram is delay circuit DC power which is based on a SCR. this circuit is a real accessible and can be active in applications. The live of this circuit is real simple. If the ability to assign is activated the capacitor C2 through resistor R2 accuses and the voltage and the capacitor just exceeds the breakdown voltage of the Zener diode D3, break it down and the
