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 digital clock of circuit, has as base one IC, the MM5314N, in which are contained all the...
The pitch of the tone is dependent upon the resistance under test. The tester will respond to...
Capacitive sensors are found in a wide range of equipment, from consumer electronics to...
This is Overheat Detector Alarm Switch using Temperature Sensor IC LM35 Electronic Suite Diagram,...
Many low pass filter circuits for subwoofer seem to be given And this is also just Another one....
Circuit The circuit diagram provided is a triac - diac electronic fan regulator that would reduce...
Aim of this project is to present a way to store a large quantity of data into microSD card in...
Despite the need for an IC, this ubiquitous interface between the modulator and audio-video...
This little circuit will pay for itself many times over the first time it is used, especially if...
As shown, the circuit consists of a dual time base circuit 556 consisting of two synchronized...
LM2002 / 2002A is an audio power amplifier integrated circuits, LM2002A high pressure protection,...
