Travel activity wearable
I developed a wearable system using a sensor tag, that operates similar to Fitbit, but for travel activities instead of fitness activities. The user wears/carries the tag during the day, and can later sync it with the phone via Bluetooth to view the travel timeline and statistics.
Bus tracking wearable
I developed a bus tracking application for three different devices: two wearables (an Android smartwatch, and a sensor tag), and an Android smartphone. I make novel use of the barometer (air pressure) sensor for extremely low-power operation (high-power location sensors like GPS are not used) and a memory-optimized lightweight algorithm.
3D graphics editor
MySketchUp is a 3D graphics editor I wrote for self-interest during my Bachelors, using OpenGL. Using the editor, we can draw simple coloured 3D scenes.
This is a simple bootloader I wrote for self-interest during my Bachelors, that loads, relocates, and runs a 16 bit C++ executable into memory from a bootable CD. You can run it on an Intel machine, or use VirtualBox.
MyThread library is a simple user-thread library I wrote for self-interest during my Bachelors, to demonstrate the "Many to One" multithreading model.
WPA password cracking
I designed and implemented a WPA password cracking tool, as part of a systems security course group project, using inexpensive GPU compute power on the cloud. The tool can crack 8 digit passwords in less than 2 hours, at a cost of less than $2.
DASH video streaming
This is a DASH-compliant video hosting service I wrote for a multimedia course project. The user can take a video on an Android tablet/phone, and upload it to a DASH video hosting server. The video can then be played in any DASH-compliant player (such as VLC player) dynamically switching between 3 streamlet qualities.
I developed a middleware for Android that supports Delay-Tolerant Network (DTN) applications. Forwarding protocols can be dynamically loaded, replaced, and customized, at run-time, to suit diverse application requirements and network scenarios. Using the middleware, I developed a mobile web application to help wheelchair people board buses easily.
