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 is a nice amplifier and very easy to make it. Its an 20W Audio Amplifier based on LM1875 IC.
The achievement of this 30 watt amp was thought to take place on a heatsink microprocessor PC....
Display interface uses the ICM7218A/B with an 8048 family microcontroller. The 8-bit data bus...
This is the schematic diagram of 300W power inverter circuit. The inverter uses power transistor...
Every key pad button generates 5 bit binary code and IC1 sends this code to the IR leds through...
Create a PC synch cord off of the extension cable by putting in a connector and having different...
I have an 01 Civic EX. A/c blew very cold. On a hot day ran into a store, came out to start the...
A touch switch for a USB powered desk lamp, and the touch switch isn`t working. The circuit...
240/24Vac(rms) transformer was used. After rectification and filtration i got about 30Vdc....
The goal is to repeat the demonstrations showing that the electrical field energy developed by a...
Shown for the precision digital timing control circuit. The controller consists of crystal...
Circuit principle is shown in FIG apparatus. When the night light irradiation on the...
