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.....

Originally, the prime harmonics were generated with 74HC4046 PLLs which were spot-on accurate but...
This moisture detector with pump controller is built around the special purpose LM1830 IC. The...
The operation of the circuit is like an enabled inverter, that is, the output Y = B provided A is...
This circuit checks the reliability of appliances so that the equipment may be used safely. The...
Using an ISD1016 audio record/playback chip (Information Storage Devices, Inc.), this circuit...
In my previous post of capacitive touch switch, it gives the o/p as long as you touch it. Means...
A wide range frequency meter is an useful tool for an electronics lab. This projects describes a...
When we modulate a carrier signal with amplitude modulation, there will be four frequency...
All you have to do is insert the pieces so that things that should connect are on the same lane....
DS1307 is a hardware realtime clock, which works on I2C protocol. Better graphics using the same...
How to build a voltmeter for DC voltage measurements without using multimeter testing This is a...
To create the circuit you will need to connect a switch as an input and an LED as an output to...
An LED is sure to fail if the current through it is too high. You will soon discover this after...
Provides overload and short-circuit protection for load while isolating malfunctioning circuit...
There are two resonant circuits tuned amplifying circuit known as a double tuned amplifier...
Colorful decorative lights loop circuit shown in Figure 3-22. It consists of the power...
