Reverse engineering presentation - Digital Alarm Clock

In this project, the principle change that would be added to the alarm clock is voice recognition. Some of the other modifications would be a larger screen display, larger buttons, louder speakers
and a solar panel that would supply power to the alarm clock which would reduce the usage of ordinary batteries. The primary target audience are the visually impaired while everybody can
use it. This alarm clock would help the user know the time and weather and listen to the radio through their voice commands.
