Sounds From The Old West
This circuit demonstrates the extensive capabilities of integration: IC1, a Type HT82207 from Holtek, performs a wide range of functions. Only a small loudspeaker and the necessary selectors need to be added. The standard 18-pin Type HT82207 is an integrated...
ultrasonic transmitter 40khz
A 40kHz ultrasonic transmitter circuit consists of three oscillators (F1, F2, and F3), with F3 generating a 40kHz square wave output. The frequency is primarily determined by components C1, R1, and an adjustable resistor (RP). The excitation output from the...
cuckoo sound generator
This circuit generates a two-tone effect similar to the sound of a cuckoo. It can be utilized for doorbells or other applications due to its integrated audio amplifier and loudspeaker.
The circuit is designed to produce a distinctive two-tone sound, replicating...
Ultrasonic Pest Repeller Circuit
This circuit utilizes two transistors and one integrated circuit (555 timer IC) to generate a pulsating ultrasonic frequency. Transistors Q1 and Q2 are configured in a direct-coupled oscillator arrangement. The frequency of the oscillator is determined by capacitor C1. The...
ultrasonic measurement circuit
This design circuit is for an electrostatic transducer used in ultrasonic measurement applications. It employs the LM1812 ultrasonic transceiver. The transducer (X1) and the LM1812 work together to transmit a burst of oscillations. The return echo is detected by X1,...
Ultrasonic switch
The transmitter part of the circuit is built around IC1 (NE 555), which is configured as an astable multivibrator operating at 40 kHz. The output from IC1 is amplified by a complementary pair of transistors (Q1 and Q2) and transmitted...
