· Completed the course scoring 67.8% in final year
PROFESSIONAL COURSEs: Completed the CCNA course from RST Forum.
AWARDS, HONORS and activities
· Achieved second place in Technical presentation 2010. Presentation topic: Rail gun and coil gun
· Participated in Technical paper presentation: topic: Gamma knife
· Participated in National level project exhibition: Presented the project: 3-lead ECG
· Conducted an 8 hour workshop about “Basics of computer hacking”
ACADEMIC PROJECT DETAILS
· Diploma final year project:3-lead Electrocardiograph using computer’s sound card. The ECG signal from the analog circuit can be directly fed to microphone input of your computer and a graph can be plotted using readily available tools.
· Third year project undertaken in third year of engineering:1. 20 pixel Camera using LEDs and an Arduino microcontroller board.
2. 5 volts to 300 volts boost converter.
· Final year engineering project: Android based multipurpose vital parameter monitoring system used for monitoring patient’s health. This system enables measurement of vital health parameters such as ECG, glucose levels and temperature. The data gathered by the independent analog front end transmits it to an Android device for viewing and it can also be uploaded to the internet for record keeping and also to get doctor’s comment on your health. In short, it is a framework for connecting patient and doctor who are remotely situated.
· Hobby Project:Designed efficient LED driver.
· Complete multi-purpose Centralized Attendance system involving an android application and a web application based on PHP, MySQL and Linux.
