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.....

A few months ago, I decided to build a compact, yet effective alarm. My demands were:- simple...
This circuit provides a visual indication of the input analog voltage level. It has a high input...
Twenty-five musical keys and 25 LEDs are provided to denote F to F" with half notes in between....
The MAX420 is operated at a gain of 191 to convert the 52 p.VI o C output of the type J...
This little tester is useful for checking vehicle electrical circuits. Two LEDs indicate whether...
This regulator is for the purpose of controlling a dc generator. The field configuration is that...
In the some building is need to using good security. For some example is using this design...
Timing capacitor (C1) produces several times constants which is used to allow large voltage...
The following schematic has been taken from buildcircuit. com. The following circuit can work as...
In contrast to an ordinary voltmeter, the input of an oscilloscope generally has one side (GND)...
The MAXQ7667 smart system-on-a-chip (SoC) provides a time-of-flight ultrasonic distance-measuring...
The Voice Changer has two different inputs, the microphone and the switches. The Voice Changer...
hi every one im not in the line to electronics so please can any one make a diagram for me that...
This page deals with the subject of replacing the crystal in any type of Temperature Compensated...
This kit is a daughter board, designed by Jan G0BBL and Tony KB9YIG, that provides four...
