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.....

The Project presented here waters your plants regularly when you are out for vocation. The...
An EL lamp is a solid state, low power, uniform area light source. Because of its thin pro ¬le...
IRF9540N Gate Charge Test Circuitis schemed in the diagram below. IRF9540N is known to be...
SO HERE YOU CAN SEE THAT USING ENCODER 4-BIT DATA ISGENERATED AND THIS DATA WILL MODULATED USING...
The cardinal principle originally designed is, the temperature value that the one-chip computer...
This circuit automatically turns a motor cycle`s headlight on and off, independently of both the...
If you do same after W2 will have maximum voltage the released S1 on W2 shortly after short...
This module is HC-06 a slave mode serial bluetooth data link. The chips is made by CSR. In this...
As shown by FIG MAX4100/4101 unit gain buffer circuit constituted. This circuit uses a small...
Circuit Description: The 566 can be connected to either positive or negative ramp generator. For...
Core elements of this circuit is the second four-input NOR gate terminal IC CD4001, the entire...
