I'm working on a interesting stuff ' Wireless controlled PC robot with wireless camera'. Phone is used as wireless cam over bluetooth. Robot is controlled with arrow keys in keyboard. movements can be seen on screen . 
here is pic 

This is just the relay driver circuit. Signals are sent through wireless transmitter operated using these relays.This bot is used in spy and in military applications.


8051 simulator

Edsim is a 8051 simulator which can be used instead of burning a program into chip. Edsim is java app, just load a hex or asm file into it and run the file. We can test the code without the actual harware.

If program is in C , convert it to hex using keil and load it . Be sure to select "INTEL 8051". 

here is link 

One more addition .. Pinnacle 52 is another simulator can be used for same purpose.


Bar codes!

Posted by Krishna Patil on March 17, 2011 at 11:06 AM Comments comments (1)

I'm getting really crazy about these barcodes! Simply point phone camera onto a code, phone reads the code and links the data , sounds really nice! Any data can be embedded using these codes. 
I nigma is a japanese company. Its 'The best' Reader i have come across . I have used lot many readers like neo reader,quickmark,sema reader, and .. nokia reader , perhaps nokia's reader is the worst among all! .

I nigma is also featured to create 2D barcodes, both QR and data matrix.
Read wikipedia : http://en.wikipedia.org/wiki/QR_code

These days many download links are embedded as QR codes (quick response) codes. Just pointing phone camera will link you to that address! You can also create a one, which links your blogging site or website . For example 

(click this link to open image in new tab. )

This will link to homepage of my website ! 

 As far now i was telling about only 2D codes, but there also 1D codes which you can see on books , products etc . Read' types of barcodes '  in this articlehttp://en.wikipedia.org/wiki/Barcode
Most mobile readers wont read 1D barcodes. They require optical scanners connected to PC via RS-232. 

Create ,read , enjoy! 

Prog- To generate random number

Posted by Krishna Patil on June 1, 2010 at 11:43 AM Comments comments (0)

Well! here is a program which can generate random numbers. This can be used in playing lotto,lucky games etc.,

Download the C souce file here


Extract the .rar file . Copy the file into C:\TC\BIN  then open the complier , compile it by pressing Ctrl+F9.

This will create a .exe file use this as a lucky num generator!

its a developed one ,basic prog can be found in topic search in C compiler only!
