Portable Password Generator for Passive Authentication

The project has been built from a modified AVR development board where the Pass key is a sweet little 5V candy bar style computer which can generate 16-bit alphanumeric passwords as fast as the buttons can be pressed.

Building A DDS Module Using AD9835

The small size and simple handling of AD9835 makes it easier to design a DDS module in order to do various digital RF modes with a PIC microcontroller.

MP3 Player Project Using AVR

An ATmega128 microcontroller is used to build this particular mp3 player that can read data from old 2.5” laptop hard drive.

Hamtronics USB Computer Control

The project illustrates the use of USB connection which is a more convenient way to interface to a computer for the Hamtronics receiver.

101 LED Displays of Bar Graph

project was based on AVR AT90S8515 and HDSP8820 to create a bar graph which can be modified to move the light from side to side that is similar to knight rider bar.

Serial ICSP PIC Programmer Device

The project allows the programming of a PIC in circuit while avoiding the need to constantly take in and out of the programmer with the bending of pins subsequently.
