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 circuit is composed of a relaxation oscillator formed by Q1 and an SCR flip-flop formed by Q2...
The shift pulse amplitude is less than 15 volts. If a stage is off, the shift pulse will not be...
Many record players unfortunately exhibit two undesired side effects: rumble (noise caused by...
This circuit will power up a water pump when the water reaches a predetermined level. Then it...
The battery charger circuit below is very simple to build requiring only a handful of cheap parts...
Below it is a circuit of power amplifiers with power output of 450 watts mono, amplifiers are...
This relay circuit is controlled by almost any type of infrared remote controller. This circuit...
The target of this project was the design of a small portable mixer supplied by a 9V PP3 battery,...
The PNP Transistor is the exact opposite to the NPN Transistor device we looked at in the...
A simple and cheap Laser Based Security System, which costs below Rs. 100. It is a simple circuit...
This simple robot, which responds to light and avoids obstacles, can be built without using a...
