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.

The original AVR-MT development board requires 10V-14V but with a little modification, the demand of power can be reduced to 5V without losing any of the display, buzzer, LED, button, or computational capabilities of the original development board. the code for Pass Key has been written in BASCOM-AVR which is an incredibly powerful Windows-based BASIC compiler that can provide help in programming AVR microcontrollers.

During the construction, the first to be done is to convert the dev board to 5V power by carefully removing some components. Two jumpers were added wherein the first jumper is soldered between the two pins of removed component while the second jumper is between the input and output pins of a removed component. The header is added then the ATtiny2313 microcontroller is inserted. The demo program of BASCOM-AVR is downloaded and run. The Pass Key code is loaded after demo program checks out, followed by the generation of password.
