I got an incredible opportunity to travel to Las Vegas and give a short talk at the 2011 AT&T Developer Summit on a few of the cool Android projects I’ve done in school. I was given only ~5 minutes to present 3 of my projects: RoadBump, FeedSpeak, and SPRIME – giving a student’s perspective on Android programming. … Read more
January 2010 Over the holiday break, I finally created an Android app that allows image processing on the camera’s raw data, and displays it back on the screen. It only uses Java on the CPU for now, but in my free time I’ll be porting the code to OpenGL ES to run on the GPU, and … Read more
December 2010 My first project as a GRA under Rich Vuduc involved accelerating 3D Fast Fourier Transforms (3D FFT) with GPUs. The project was basically porting the open-source P3DFFT code (written in FORTRAN) to run on GPU(instead of CPU) clusters using CUFFT. Update: 04/16/2011 – This project has morphed into a SC11 paper – a draft … Read more
September 2010 I got an incredible opportunity (at the last minute!) to give a short talk at Nvidia’s GTC 2010 on what I learned about GPU matrix multiplication, while at AccelerEyes over the summer! Watch presentation here (I’m 19 minutes in)!
July 2010 OK, it’s not really a project, but I did learn a lot about GPU matrix multiplication over the summer, working at AccelerEyes. I re-worked the back-end CUDA code for the MTIMES Jacket function. I also modified it to accelerate SUM, MIN, and MAX. Checkout my MTIMES wiki page!
May 2010 FeedSpeak reads your Google Reader RSS news feeds aloud to you using Text-To-Speech. FeedSpeak started as a class project, but I now continue development on my own free time. Read the XDA-Developers blog post about FeedSpeak! (Note: reviewed for v1.9.6) FeedSpeak Pro for Android on AppBrain FeedSpeak Lite for Android on AppBrain … Read more
April 2010 Simple Powerline Remote Interactive Monitor and Enforcer SPRIME is an outlet that allows you to monitor power consumption and control power usage remotely, using a computer or even an Android phone. SPRIME is an open-source smart-grid technology. SPRIME GT-RNOC poster: SPRIME pictures: Awards SPRIME has made it on Hack-a-day! SPRIME has won … Read more
April 2010 I got a chance to use a 3D Printer and a Laser Etcher in one of my undergraduate CS classes. I took the opportunity to make some Motorola Droid mods. I got to laser etch a sun onto the back of my Droid’s battery cover. I also 3D printed a car mount for my Droid, that attached to … Read more
April 2010 I find graphics card programming fascinating. I presented a UROC Poster on GPGPU Molecular Dynamics analysis and visualization on the GPU at the 2010 Georgia Tech Undergraduate Research Symposium. I also had a cool demo set up of the system running (above), along with my Android bonds visualization client.
March 2010 I recently started playing with the Nvidia CUDA SDK Samples involving image processing. I extracted the SobelFilter kernel and made it run off my USB webcam using OpenCV – the two live modes are single-channel-gray and three-channel-rgb. I wrote two different basic kernels on my own that did binary thresholding and found the most dominant RGB value. Now on Google Code! cam-cuda-sobel
