This is a simple electronics circuit of clap switch project. If you are a beginner electronics learner, and love to get new project experiment then this is a great circuit for you. This circuit can on/off a 220V electronic device like fan, lamp by the sound....
-
On the primary winding of the first IF transformer there is no capacitor. Does that mean it has only one tuned circuit, and the primary coil is just an inductive coupling The routing of the twisted pair couldn`t be done exactly the same every time. Was it....
-
Here is VU meter 10 LED circuit, This simple LED VU meter has only a few parts but it is useful as an indicator for the sound. The circuit is built around an...
-
Astable Multivibrator can be designed by using 555 timer IC, Op Amps and also using transistors. The 555 IC provide accurate time delay from mille seconds to hours. The frequency of oscillation can be controlled manually by simple modification. This is a....
-
The circuit below is similar to designs using unijunction transistors to generate the triggering pulse. The unijunction is replaced by a two-transistor "flasher" circuit that drives a pulse transformer. This type of circuit gives a wide range of control....
-
The circuit described here is that of a metal detector. The opera- tion of the circuit is based on superheterodyning principle which is commonly used in superhet receivers. The circuit utilises two RF oscillators....
