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.....

Monitoring a flame and directly switching a 120-V load is easily accomplished using the Ll4G1 for...
This simple receiver AF amplifier can supply several hundred milliwatts to an 8- speaker. The...
The tester consists of a rectifier circuit and a multivibrator circuit. The ac voltage is...
Have you ever wanted to make a line following robot but the infrared sensors were too expensive...
The 555 on the right is wired as an alarm sound generator and the second 555 timer on the left is...
This stereo balance indicator circuit diagram is designed using few common external components....
Experimenting with a vacuum tube VCO similar to the one in the link below, but with a few...
To start with, there is a step-down mains transformer with a secondary winding rated at 24 V/3 A,...
Usually when the car door is closed, the dome light just goes OFF. With this circuit, you can...
This acoustic sensor was originally developed for an industrial application (monitoring a siren),...
LM4782 uses the system of protection of National Self Peak Instantaneous Temperature ( Ke)...
As shown in the timer 555 is triggered by the positive trigger pulse, then a negative output...
As shown, the OPA277 constitute inverting amplifier, inverting amplifier use high input...
Color light-emitting diodes with different colors of light can indicate the operating electrical...
Electronic tube amplifier lovers started his art that simple, excellent single-ended Class A...
