Atmega 8 FM Radio

Atmega 8 FM Radio

This is the second FM Receiver i have made using MCU. last time i have used a arduino nano board to build this.this time i have decided to use a Atmega8 MCU and a external 16Mhz crystal instead of a arduino board.and i have ued a 16x2 LCD display + a external eeprom to save the stations.FM receiver module is the same as before its the TEA5767.eeprom and TEA5767 communicate via I2C.
i have utilized the rotary encoder to tune the stations, this time the rotary encoder don't use interrupts.

how ever i have used the arduino IDE to develop the code.it seems the arduino IDE is more convenient to use when come to development of new prototypes.

java swing face recognition

java swing face recognition

I have made a face detecting app using java swing and open-cv.web-cam support also added so live face detecting supports.you can select the cam source as well.

git repo : https://github.com/stark9000/opencv-java-face-recognition


this might need little tweaking to get it to pro level, this is basic testing app only.
source code is provided so you can dev it to your expectations.


java opencv Number Recognition

java opencv Number Recognition

This is java and open-cv integrated number recognition system.i have added web-cam support to the project.

and i have included test image file for testing purposes. how ever if the web-cam not present project won't run.you can tweak this to work without web-cam.

Java Swing Browser

java Swing Browser 

Recently i have to build a java swing embedded browser for some purpose.i came  across the jcef - java chromium embedded browser.i have success fully integrated this to java swing application.
here you can see the video of " in action " of this browser :
