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 general-purpose 10-W audio amplifier for moderate-power PA or modulator use in...
Want to send your audio information via a light wave across the room I built this simple circuit...
The complete circuit diagram is shown in Fig. 1. Heart of the system is lC2, National`s MM5402...
Using an optocoupler ( MOC3021 ) to sense the On/Off state of an electrial appliance using a...
The circuit detects a sudden shadow falling on the light-sensor and sounds the bleeper when this...
The module provide a pre wired multiplex of 4-digit common anode LED, that`s great. See the...
What about the 10K resistors at the bases of the transistors, and the 1K resistors at the...
An 30 Watt audio amplifier circuit with TDA2040 shown here. TDA2040 is class AB amplifier...
It is impossible to imagine present day society without any batteries. Count the number of...
A VU-meter is a very common instrument usually installed on audio Hi-Fi amplifiers and is used to...
IC1 generates 150 µSec. pulses at about 80Hz frequency. Q1 acts as a buffer and Q2 inverts the...
The Shay is equipped with flickering ashpan and firebox lights. These are simulated with LEDs....
The usual procedure for the production of sustained oscillations in tuned L-C networks is to...
As shown in FIG constituted by 915MHz RF2155 power amplifier application circuit. Radio...
As shown, the circuit uses a zener diode D1 achieve overvoltage protection, a diode rectifier...
By phone automatically when the lamp base circuit NE555 and optocouplers constituted a call at...
