TI’s eZ430 Chronos – tinkering 101

I recently bought TI’s Chronos eZ430 – 433 MHz development kit. Basically, it is a watch with a bunch of sensors and a controller that can be programmed wirelessly over the 433 MHz ISM band. Yes – I know it is bulky and has a huge ‘Texas Instruments’ logo on it. But, as long as…

Practical Trials – Videos are here!

We have almost come to the end of our project – An Indoor Navigation System using OpenCV on BeagleBoard-xM. It has been a wonderful five months over which we have seen many ups and downs. Following are the videos of the practical trials of our system – the first has the camera stationary and the…

A working knowledge of software releases

Software releases are huge events! And as time has progressed, the method of software releases has also undergone a number of changes. There come various stages in the release of software. And though it is not a very complex phenomenon to understand, many people don’t actually know why there are different stages of software releases…

CLAHE in OpenCV – Removing the Seg Fault

First of all – I am not going to discuss CLAHE (Contrast Limited Adaptive Histogram Equalization) here. This is because there is a lot of standard material available on the internet as well as in books for studying the algorithm in detail. This,  this, and this should be more than enough to fill you up on CLAHE. In this…

Paper Prototyping — prototyping economically!

I recently stumbled upon an article on paper prototyping – an economic prototyping technique that not only saves money but also a lot of time which was spent in writing code and developing data structures. Paper prototyping basically uses paper-based designs for testing out layouts. Sketches are drawn on paper – that paper may or…
