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 real analog synthesizer to build using easy to get components, capable of a wide range of...
Many devices operate from a car"s 12-V electrical system. Some require 12 V; others require some...
Switching regulator subsystems intended for use asdc to dc converters. 3V to 40 Volt DC Converter...
The voltage measurement is very general in electron technology at present, accuracy requirement...
60MHz Frequency Meter / Counter measures frequency from 10Hz to 60MHz with 10Hz resolution. It is...
This is a circuit that used to main pulse. The pulser is intended to switch the mains voltage on...
SMPS design and analysis requires an understanding of many different areas of study. This article...
This is a circuit that can be used for detecting sounds and providing an output signal when a...
This article will show you how to build your own version of the Fire-Stick infrared remote...
Field strength meter circuit is a very useful device for measuring the RF output of any...
1999 S10 2. 2L Fuse Box Quesion. There are two (what appear to be) main power terminals on the...
This article describes one reliable, simple, and universal method of interfacing MaxTrac, Radius,...
A while ago I was doing some fairly trivial repairs on a Philips portable radio/CD/cassette...
The purpose of this project is to visually communicate the effects that frequencies have with...
These versions are the original UV-3R, the UV-100, UV-100 MKII, UV-200, UV-200 MKII, UV-3R MKII,...
Penetrate the motor phase line with a transformer when the induced voltage is ov. When one phase...
