This document describes a project report for a DTMF based mobile control robot system. The system allows a robot to be controlled remotely using Dual Tone Multi Frequency (DTMF) tones generated by a phone. It uses an 8051 microcontroller as the main controller, which receives DTMF tones using a decoder module. Based on the tones received, the microcontroller controls motors and other devices on the robot. The report covers the hardware components used - including the power supply, DTMF decoder, motors, and microcontroller. It also discusses how the system works and the software used to program the microcontroller. The aim is to build a basic autonomous robot that can be operated remotely using a phone.
Project Report on HOME AUTOMATION USING DTMF.
The Project “Home Automation using mobile communication” has different sections such as:
1.Microcontroller
2.DTMF decoder
3. Relays
. This project we propose a unique System for Home automation utilizing Dual Tone Multi Frequency (DTMF) that is paired with a wireless module to provide seamless wireless control over many devices in a house. This user console has many keys, each corresponding to the device that needs to be activated. The encoder encodes the user choice and sends via a GSM transmitter. The GSM receiver receives the modulated signal and demodulates it and the user choice is determined by the DTMF decoder. Based upon this the required appliance is triggered.

Seminar report on solar tree (by Vikas)dreamervikas
Now a days with the growing population and energy demand we should take a renewable option of energy source and also we should keep in mind that energy should not cause pollution and other natural hazards. In this case the solar energy is the best option for us.
so based on solar energy the solar tree is formed and it acquire very less land.
Mind Melds and BattleBots: Creating the Right Kind of Designer/Developer DynamicWebVisions
Improving the designer/developer relationship is an ardent wish on a lot of project teams. And yet, a lot of excuses seem to be made for bad relationships between designers and developers… several of which are tied to when and how each are involved.
Do these sound familiar?
“There’s not enough budget to involve all members of the team from beginning to end.”
“We don’t want to limit designer creativity too soon by bringing tech into the process.”
“We don’t want to waste developer time at the beginning when there’s nothing fully defined yet.”
“If we design a detailed enough style guide, development should be able to implement without retaining a designer through implementation.”
How do you find the right balance of involvement without breaking the budget - and make the most of the skills that each team member can bring to the table?
In this presentation, Carolyn Chandler (Experience Designer and instructor) and Don Bora (Developer and iconic tech mentor) will take you on a journey through the main stages of a project from both sides of the divide.

In this thesis two different circular shaped proximity feed antenna are undertaken, both in the
area of compact RF/microwave circuits design. The first design involves the design of a
Circular shaped radiating patch antenna with Semicircular ground plane and ring of circles. A
study of several circular shaped microstrip antennas reported in the past has been carried out.
In this research, a method of reducing the size of a printed slot-ring antenna for dual band
applications is proposed. The reduction in size is achieved by introducing proximity feed
technology with circular shaped feed line.
The minimum axial ratio of 0.3 dB is obtained at 1.27 GHz, which is the operating frequency
of the antenna. The size of the proposed antenna is reduced by about 50% compared to a
conventional Circular Polarization slot-ring antenna and it displays a Circular Polarization
bandwidth of about 2.5%. The simulated results are presented, and they are in good
agreement. The small size of the antenna makes it very suitable for use in modern
RF/microwave wireless systems which require compact, low cost, and high performance
circuits. Moreover, its Circular Polarization behavior makes it more applicable for
applications such as satellite communications.
The second geometry in the thesis involves the design of a compact circular microstrip
Antenna using semicircular ground plane attached on both sides of a square geometry. The
measured dual frequency band with center frequency is 3.0 GHz. The Antenna demonstrates
about 21% bandwidth with antenna gain of 1.8 dB in the radiation band, a return loss of less
than -10 dB is achieved in this work. The simulated results are in good agreement. The
proposed antenna is very reliable for use in modern wireless systems which require dual band
geometries having compact size, low insertion loss, high selectivity, and good antenna gain.
Li-Fi audio transmission is the transmission of wireless data by using visible light as a medium of communication in which the receiver section interprets the incoming light which is detected using a solar panel and converts to the audible sound signal with the help of a speaker.
