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 real core of the dimmer system. This circuit generates ramp 100 Hz signal which...
The circuit shows a simplex fiber link between the NE5080 transmitter and the NE5081 receiver....
Here is a very simple passive headphone box that I have made that works really good. I have used...
This text describes preliminary plans for a frequency meter for a bat detector. It measures the...
A commercial motor controller is more than simply a circuit to alter the speed of the motor and...
Circuit The circuit diagram provided is a triac - diac electronic fan regulator that would reduce...
This chapter contains the description of a simple development board for the study of the 8051...
This article describes the Flip-Flop Flashers, Buzzers CIRCUIT (2N4401). The content is very...
A 1998 tracker it has 1. 6 multifuel port injection system. The vehical is hard to start. when we...
Tesla coils are air-core, resonant transformers. Working at high frequencies, they can generate...
This page describes a color clock that displays the time using two RGB LEDs, one for hours and...
Charging apparatus shown in schematic circuit, the maximum output current of 20A, the maximum...
Circuit as shown, consists of four light-controlled electronic switches, timing circuits, voice...
