My first Mobile Phone App: The flashing tail light!

Cycling on crowded, poorly illuminated city streets can be a nightmare thanks to the recklessness of vehicular traffic. Cyclists, like pedestrians, are known to be accident prone. Lack of separate cycling tracks adds to their predicament. Considering the ubiquitous presence of mobile phones, I realised that these gadgets can be deployed quickly as a safety gadget if used as a tail light. All one needs is a transparent backpack. Install my piece of software on any MIDP2 compatible java enabled mobile phone and enhance your safety as a pedestrian or a cyclist on city roads!

My .jar package can be downloaded here. (I have used Sun's J2ME Wireless Toolkit) Install the app on your phone and you are ready to go!

My Live Score Notifier Gadget

I have come up with this Live Score Notifier Gadget. Sites like cricinfo.com do provide live score updates. To save screen real estate and for pure fun, I built this Live Score Notifier gadget. The Live score is automatically streamed every 30 secs (value can be set by user) and displayed on the Notifier’s LCD panel. Users can decide upon a level of update notification. I have kept it at a minimal wherein only the score and wickets are displayed. One can also display batting and bowling statistics. The update process is entirely automatic. One is only required to indicate the Live match one is following. In the snap it happens to be the Third Ashes Match when Australia saved the day with a final score of 375/5.

Anybody interested in details like code and circuit schematic, do contact via email.

Konkan Trip


Small winding roads make way through thick greens,
As the road curves along it reveals the typical Konkani scene,

There are houses with thatched roofs,
Surrounded by boisterous shoots,

There are evergreen paddy fields,
And stocks of cattle feed,

Through a rare green cover clearing we catch the first glimpse of the sea,
It is a picture postcard perfect scene,
As cool but humid breeze brings an occasional downpour over a distant devrai,

Traces of golden sand indicate that we are nearing the beach,
Soon a rail track glides over the sea,
While a lighthouse over the shore cliff signals our arrival to boats out on a fishing spree,

Konkan is surely the 'jari cha padar' of nature's unfurled 'saree'...
Dotted with peaceful temples and this satisfied look of glee!!

My Propeller LED display

Here is a video of my all new propeller LED display. The display uses six Light Emitting Diodes (LEDs). An IR Tx Rx pair refreshes the display with each motor rotation. The pattern to be displayed (in this case 'OM') is programmed in a uc (I have used an Atmel uc).
I can now display any message on my Propeller LED display!
Enjoy!

(Note: Camera frame rate limits visualization of actual display persistence and clarity.)
