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 design used to measure air or gas flow works by measuring the energy required to maintain a...
This device was designed to replace the original digital clock in a Fiat Ducato 1992-1994,...
You can buy ready-made programmers, but why spend money when you can build it yourself from parts...
This article means to utilize your old PC to be come a simple controller. Many old PC like 8088...
This version of the Link is for those who really need a good cheap intercom that will work...
First you will have to use a opamp like ne5532, than calculate the frequency you want on each...
This circuit provides you with wireless audio and visual transmission to a TV. The TV acts as a...
The White`s Classic I was a very simple, easy to use machine, ideal for the entry-level...
For power supply is needed transformer with two individual secondary 12V windings. If you want to...
The purpose of this project was to develop a stepper motor driver for 2-phase unipolar stepper...
This page`s mission is to help you understand how to use the STA013 MP3 decoder chip in order to...
The following is a layout of my repeater system and what was needed to get it on the air. The...
AD524 low-drift (drift voltage 0.5mV, maximum drift 25 mV door C), low noise (0.3mVp p,...
