SOLAR GRASS CUTTER WITH SPRAY
$168.28$156.26We present an Arduino-based automatic robotic system that is used for cutting grass or
lawns, mostly healthy grass which needs to be cut neatly like in a public park or a private
garden. The purpose of this proposed project is to design a programmable automatic pattern
design grass cutting robot with solar power which no longer requires time-consuming manual
grass-cutting and that can be operated wirelessly using an Android Smartphone via
Bluetooth from a safe distance which is capable of cutting the grass in indeed required shapes
and patterns; the cutting blade can also be adjusted to maintain the different lengths of the
grass. The main focus was to design a prototype that can work with a little or no Physical
user interaction. -
SOLAR POWER BANK WITH WIRELESS CHARGING
$146.64$134.62In our proposed system we are used wireless charging ,it is a type of charging method which uses an electromagnetic field to transfer energy through electromagnetic induction. Energy is transferred between devices (transmitter and receiver) through the process of mutual induction.

Solar Power Vaccine Storage Refrigerator
$156.26$141.84Large areas of many developing countries have no grid electricity. This is a serious challenge that threatens the continuity of the vaccine cold chain. The main alternatives to electrically powered refrigerators available for many years—kerosene- and gas-driven refrigerators—are plagued by problems with gas supply interruptions, low efficiency, poor temperature control, and frequent maintenance needs. There are currently no kerosene- or gas-driven refrigerators that qualify under the minimum standards established by the World Health Organization (WHO) Performance, Quality, and Safety (PQS) system.

SPEECH CONTROLLED HOME APPLIANCES
$84.14$63.71The main objective of the project is to develop a speech controlled home appliances that load is ON/off when a voice signal is sent from the users mobile. While the user sends the signal from the mobile, the remote operation is achieved by any smart-phone

Speech Recognised Notice board
$102.17$60.10Notice Board is primary thing in any institution / organization or public utility places like bus stations, railway stations and parks. But sticking various notices day-to-day is quite a difficult process. A separate person is required to take care of this notices display. This project deals about an advanced hi-tech wireless notice board.

SPEED CHECKER TO DETECT RASH DRIVING ON HIGHWAYS
$90.15$60.10The aim of this project is to develop a device to detect rash driving on highways and to alert the traffic authorities in case of any speed violation. Accidents due to rash driving on highways are on the rise and people are losing their lives because of others mistakes. In the present system, to detect rash driving the police has to use a handheld radar gun and aim at the vehicle to record its speed. If the speed of the vehicle exceeds the speed limit, nearest police station is informed to stop the speeding vehicle. This is an ineffective process as after detecting one has to inform the same and a lot of time is wasted.

SPEED CONTROL OF INDUCTION MOTOR USING ACPWM
$100.97$88.95This project attempts a new speed control technique for the single-phase a.c. induction motor. It presents a design of a low-cost; high-efficiency drive capable of supplying a single-phase a.c. induction motor with a PWM modulated sinusoidal voltage. The circuit operation is controlled by an 8051 family microcontroller.
