6 Axis Motion Data Logger   [Oct 2015-Jan 2016]
GSM Based Tracker with μ Energy Harvesting [Feb-Nov 2013]

    Completed as a partial fulfillment for the final year undergraduate project, this device is capable of efficiently harvesting from as low as microwatts (μW) to milliwatts (mW) of energy generated from a variety of sources such as solar, thermoelectric, electromagnetic and vibration energy. The strength of energy scavenging capability of this design emerges from the capabilities of the TI BQ25504 IC. The MSP430 MCU further extends the unit’s lifetime with it's ultra-low power capabilities. This conceptual system was formulated as per the idea of Dr Malitha Wijesundara (my undergraduate FYP supervisor) with the intention of enabling a mechanism to log prolonged locomotion data of wild elephants to formulate a solution to the Elephant Human Conflict (HEC) in Sri Lanka.

A Model Radar [November 2012 - January 2013]

    During the internship at the Airport and Aviation, I undertook a project to develop a simple circuit that demonstrates the basic concept of a radar using reflected ultrasonic waves. The project was presented at the annual national exhibition "Deyata Kirula", 2013. The project involved no programmable devices.

    I also use this opportunity to express my heartfelt gratitude to the world's best analog electronics designer, Mr. Ananda Perera, who during the time of my internship was a Senior Electronics Engineer at the Electronics and Air Navigations Unit at the Airport & Aviation Service, Sri Lanka. I cannot express enough the gratitude I have towards him for teaching me the power of analog electronics and spending his valuable time mentoring me throughout my internship at AASL.
