Every innovations starts from a simple day to day life problem like you watching IPL in TV and suddenly the current shuts off, fortunately you will find another way to watch the match via mobile network. Similarly, I too had faced a problem of frequent drains in mobile battery while travelling There are many innovative projects on wind powered mob

ile charger which looks huge enough to produce 5v dc but they weighs more and bulky. I gathered some information from them for my project and started with a basic 12 volt DC motor. I used it to generate power for my mobile phones, and it ended up with failure. Then I used an feedback amplifier circuit but it was so huge. A Multi-source Pocket Energy Generator(MPEG) is a portable and constant power source that can be utilized anywhere around the world. The world is in demand of proper utilization of renewable sources owing to frequent power failure. The MPEG is the best choice of interest for the utilization of alternate energies, facilitated with high portability. Now my aim is to construct a portable power source that depends on renewable energies with efficient utilization of available resources. The MPEG receives energy from renewable resources like wind or solar energy and convert it into an electrical energy with output 5volt DC. In the absence of any of the above renewable sources, the 5V MPEG can be used with a single 1. 5 volt battery to produce 5V DC output. The problem of bulkiness, armature reaction in mini-wind generator and irregular availability of renewable sources are recovered by using our methodologies. MPEG consists of a power generator, an amplifier circuit and an output port. The power generator may be a wind sourcing DC generator(range may be 1 v to 3 v) or a solar cell of dimension(4cm x 2cm) owing to...
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.....
