Australian singing legend Alston Koch who was born in Sri Lanka has attracted worldwide interest with his tribute song to the world's greatest bowler in the history of cricket, Muttiah Muralitharan. 'Murali' is now the world's leading wicket taker, he swept past Australian spin bowler Shane Warne's record recently when Sri Lanka played England in a 3 test match series on the island.

In London, Muttiah Muralitharan received a standing ovation when his name was mentioned at the 'We, Children of the Pearl' cultural show held at Imperial College on 15th December 2007. Murali was hailed as a wonderful example of diversity in action in Sri Lanka.

Alston Koch has recorded the only tribute song officially endorsed by Murali himself.Alston told World Music Central that he has also released a music video to go with his 'Murali' song. It has been played by radio and TV stations in three continents and been even mentioned on the BBC's 'Test Match Special.'

He is the only Sri Lankan-born singer song-writer to be signed to an international record label and have success in Australia, Asia and Europe with Platinum & Gold record status.

Infrared remote control has been around for a very long time now, and we tend to take it for granted. Yet, it is a marvel of modern technology, which allows a whole variety of devices to be activated with the touch of a button. Remote control handsets are so abundant that they may be purchased new for a few pounds, which makes them viable items for experimentation. There are dedicated chips available that will decode the signals from a particular handset, however, with the flexibility and cost effectiveness of the PIC range of microcontrollers we can develop a decoding subroutine that may be placed into your own programs, or used as a standalone infrared to RS232 converter.

It is not my intention to teach you how to program a PICmicro, therefore, throughout this article; it is assumed that you already have some knowledge of either assembler or PicBASIC Pro. And that you have a means of programming the PIC16F84. For more information concerning the PicBASIC range of compilers, as well as an assortment of programmers, visit Crownhill Associate’s dedicated web site at www.picbasic.co.uk. For information concerning assembler programming, visit Microchip’s web site at www.microchip.com.

Here is the circuit diagram. I successfully built this.



The out put of RS232 is like this

IR_BUT<Button Code>\rIR_DEV<Device Code>\r

Button Code is the value assigned to the button i.e E00(in hex) is the value for for Number 1 button
Device code is the value assigned to the device.

Source Code written is PICBasic

Everyone knows about Hearts Game in Windows. We have been given an assignment of Middle ware Architecture Course unit to recreate the Hearts Game which can be played in a Network using RMI(Remote Method Invocation) and RPC(Remote Procedure Call). This program is written in java.
Here, I didn't implemented all the features in Hearts Game. But basic rules & functionalities are implemented. You are welcome for comments.
