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.....

Here the popular 555 timing IC, is wired as a monostable. The timing period is precise and...
VUTRAX (pronounced View-Tracks) is the major professional Electronics schematic and PCB (Printed...
The two basic parts for working with IR are the emitter and the detector. The emitter is...
The water detection time is less than 10 seconds. Since the microcontroller enters a low...
Each and every time a phone on the same line or calling numberis taken off-hook, the circuit will...
When power is first applied, three things happen: the light-driving transistor (Ql) is switched...
The following diagram is the circuit diagram of 20W power amplifier which build based tube...
This oscillator is called the Colpitts oscillator and voltage controlled to achieve the FM...
The frequency meter can be used to measure the frequency of 10 Hz-60Mhz. The frequency meter has...
This is an actual reverse engineered circuit diagram of the one transistor circuit most commonly...
There are so many circuits available for infrared Burglar alarm but transmitter section of these...
The circuits incorporate two FM Demodulator TDA2555 systems to perform the Demodulator functions...
In order to meet the needs of the control loop, often require electromagnetic relay or transistor...
