Remote-Controlled Switcher
This single-cable system transmits composite video (NTSC, PAL, or SECAM), power, and channel selection signals. The interface end of the circuit delivers 10 V down the cable, pulses the supply voltage to transmit channel-change commands, and buffers the received video...
how to make electronic siren circuit
The sound produced mimics the rise and fall of an American police siren. When first powered on, the 10µF capacitor is discharged, and both transistors remain off. Upon pressing the push button switch, the 10µF capacitor begins to charge through...
POLICE SIREN USES FLASHER
A low-drain circuit powered by a 1.5-V cell utilizes National LM3909 flasher integrated circuits (ICs) to replicate the "whooper" sounds characteristic of electronic sirens found in some city police cars and ambulances. Two flashers are necessary to create the required...
Home security system
The security system application and program offers a simple demonstration of the BASIC Serial Interface. By adding only a few door and window switches, a transistor, a siren, and a few lines of BASIC program the interface can become a...
Siren Circuit
An LM380 audio IC is configured as a feedback audio oscillator. A transistor astable modulates this oscillator at a low frequency, which produces a siren tone.
The circuit utilizes the LM380, a power audio amplifier IC, which is configured to operate...
SIREN ALARM SIMULATES STAR TREK RED ALERT
The signal begins at a low frequency, increases over approximately 1.15 seconds to a high frequency, pauses for about 0.35 seconds, and then starts to rise again from a low frequency, continuing this pattern indefinitely.
The described signal exhibits a repetitive...
3V Sweeping Siren Alarm
A loud sweeping siren-type audio sound generator powered by 3V. The circuit utilizes an LTC1799 precision frequency generator from Linear Technology and a 74HC14 hex Schmitt trigger from Texas Instruments to perform various functions. One section is configured as a...
