This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of.... -
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is.... -
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to.... -
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This.... -
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the.... -
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,.... -
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the.... -
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power.... -
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....

The Electronic Cash Register (ECR) keeps track of sales transactions quickly and effectively. An...
The acoustic filters are met in various points in the sound systems. The knownest application...
The basic die circuit is given. A 555 timer, ICl, is connected as an astable multivibrator. This...
Simple function generators normally provide sinusoidal, rectangular, and triangular waveforms,...
A 4017 decade counter/divider driven from a low-frequency oscillator (Ul-a and Ul-b) is used to...
Our car radio has the annoying habit of forgetting what part of a CD it was playing when you turn...
This is the circuit diagram of USB powered computer speaker, or it widely known as multimedia...
Tank circuit C2 and L1 is used to tune the transmitter. The antenna is coupled to the transmitter...
Most of people ask TV transmitters. So Today I`m going to give you a very useful circuit diagram....
The transmission distance can be increased greatly by replacing the transmitter`s red LED with a...
Many modern motherboards are equipped with an infrared data interface compliant with the IrDA...
This is the circuit diagram of a very powerful and efficient Ni-MH battery charger using IC...
A very lab adjustable power supply that can provide an output voltage between 0 and 60 volts can...
Controlled rectifiers are line commutated ac to dc power converters which are used to convert a...
Prior to the advent of FET-input digital multimeters (DMMs), the vacuum tube voltmeter (VTVM) was...
A microcontroller is a single-chip computer. It has internal RAM, ROM, timers, counters,...
1C is SK - 2 integrated voice, when the object hit the sound is received in the body Xi ester...
As shown in the audio circuit is commonly used in color television sets (TDA2009) Pin 1: 1.2V--...
