Third Eye for Blind

According to estimates from the World Health Organization (WHO) Prevention of Blindness and Deafness Program: About 285 million people are visually impaired worldwide: 39 million are blind and 246 million have low vision. To solve this problem we are going to make one of the best wearable technologies based innovative device which will detects nearby objects or obstacles and notify with buzzer. This devices is called “THIRD EYE FOR BLIND PERSON” Now a days there are so many instruments and smart devices for visually [...]

Laser Security System, LDR Based Security System

Laser Security System / LDR Based Security System is type of alert system that uses laser light and a photo resistor sensor LDR (Light Dependent Resistor).  It is also called wireless Light based fencing security systemThis security system can protect our homes, offices, banks, lockers etc. from unauthorized access. There are different types of security systems available in market but laser based security system is an important and efficient type alert system.

Wireless AC Power Detector

We all know that electric shock can cause serious injury or even death. In order to avoid injury, prior to starting work on an electrical box such as an AC mains switch-board or a power supply, for example, you must first verify there is no AC voltage.Problem is that how you can be sure that there's no voltage remaining?Here is a solution that helps you test cable without requiring any physical touch with cable . This circuit is called Wireless [...]

Touch-less Doorbell

We all have a doorbell at our homes. When a guest comes to our house, they search for the doorbell switch and then ring it to let us know their presence. If who came to our house and unable to find doorbell, else person is so short then they cannot find the doorbell in this case we need a solution that can find the presence of a person and rings the doorbell automatically.Here we are making an object sensing [...]

Wind Mill With Electric Switch

Wind mill is a machine that converts the wind energy to another form simply stated, a wind mill works the opposite of a fan. Instead of using electricity to make wind, like a fan, wind mill use wind to make electricity. This project shows basic concept of wind power generation. This is prototype of wind mill.Parts Required : DC Motor with connector pin -1Fan Blade – 1 LED – 1Wind mill base-1Motor Base – 1LED Base -1Safety pin -1Thumb pin – 4Battery Cap-1Buy [...]

Simple Electric Circuit with Switch

Electric circuit provides a complete path for electricity to pass between two terminal of the electricity source (Battery, cell etc).In an electric circuit, the direction of electric current Is taken to be from the positive to negative terminal of electricity source (Battery, cell etc).Basic Electric Circuit With SwitchIn other side we can said that, A circuit is a closed path that electrons flow along. A simple electric circuit contains a power source (battery), wires, and a resistor (light bulb). [...]

Wind Mill || Electricity Generator DIY (100 % Working )

Simply stated, a wind turbine works the opposite of a fan. Instead of using electricity to make wind, like a fan, wind turbines use wind to make electricity. The wind turns the blades, which spin a shaft, which connects to a generator and makes electricity.Parts Required : DC Motor with female pin -1Fan Blade – 1LED – 1Wind mill base-1Motor Base – 1LED Base -1Buy this DIY Component Kit from AmazonASSEMBLY& WORKINGArrange all the parts as shown in pictureBlow the fan with full [...]
