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 controls resistive and inductive loads up to 2,500W. Its main functional device is...
The LT1007 is capable of providing excitation current directly to bias the 350-0 bridge at 5 V....
It has been designed as a panel meter and can be used in DC power supplies or anywhere else it is...
The brief with this project was to produce cost effective electronics that could be assembled by...
This is the circuit diagram of the simplest single chip AM radio. The circuit is designed around...
A preamplifier operating on a single supply and suitable for use with high impedance type crystal...
The BU8872 and BU8872FS are DTMF receiver ICs developed for use in telephone answering machines,...
Have you ever seen the stairs to one of the upper stories in your house turn into a waterfall Or...
The 900 Hz tone is generated with an LC-oscillator. The "L" part of the "LC" is provided by the...
This is a "beta release" schematic. Use at your own risk The idea is to add this circuitry to a...
To be used with PC connected to video projectors, where the lighting controller may require...
The bipolar junction transistor is still one of the cornerstone`s of modern solid-state...
Analog switches alternately pass, off the input signal by the low pass filter to make pulsating...
