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.....

There are many ways to create a stereo effect. If you were miking a piano, a string section, or...
This simple circuit generates both white and pin noise. Transistor Q1 is used as a zener diode....
A VOX is a voice-operated switch that is often used as a substitute for the press-to-talk switch...
The circuit has a frequency response that ranges from 100 Hz to 3 MHz; the gain is about 30 dB....
LM4880 is a dual audio HiFi amplifier IC from National Semiconductor. This headphone amplifier...
AC power is rectified and applied to the motor in the same polarity when the momentary switch is...
This diy digital thermometer circuit can measure temperatures up to 150 °C with an accuracy of ±1...
I`ve been putting in a lot of extra hours at work the last week in anticipation of an editing...
This is a 25 Watt basic power amp that was designed to be (relatively) easy to build at a...
This lead acid battery charger circuit is designed in response to a request from Mr. Devdas. C....
A high-input-resistance op-amp, a bridge rectifier, a microammeter, and a few other discrete...
Making an lcd digital watch alarm and thermometer. C source code downloaded converted that C file...
This page is a revised version of the original submission of an article entitled "Better Bachmann...
Build a library of circuits and service data for old valve and transistor radios. There are many...
A very simple circuit forexperiments with AT90S2313, 2x16 LCD display and 4x4 keypad. The clock...
Develop a self contained unit that can automatically control up to four DCC equipped engines,...
The world`s first practical crystal amplifying device, in 1948, and the dawn of the commercially...
