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.....

This circuit is a simple IR detector for testing IR remote controllers. The circuit is based on...
This section describes the various systems aboard Chinook II. Our approach is to use reliable and...
Did it ever occur to you that an array of white LEDs can be used as a small lamp for the living...
There are situations in home automation applications where you would like to measure the level of...
This electronic game is simulation of one-arm bandit game. Electronics hobbyists will find it...
A 24V DC power supply circuit using LM7824 IC. LM7824 is a 24V 1. 5A fixed output voltage...
This Time Domain Reflectometer (TDR) based on circuit idea published in Electronics Design...
To obtain such a monitor it`s enough to connect a resistor in series with the bulb and connect at...
This is a common control voltage in industrial and telecommunications equipment, so the relays...
The 82C55 and 7 segment decoders on the display board will be changed to a group of shift...
I built one of these with the RS-232 option many decades ago. It a three channel HF receiver (5,...
Amplifier circuit shown in Figure r) 100 shown, with two TDA2030 integrated circuit as a power...
