Wise Clock 3
is an open-source, highly hackable geeky clock that shows a lot more than the time. Its main function is to display user-editable quotations retrieved from an SD card (like those used in photo cameras).
In addition, Wise Clock 3
can show the time in "Pong" mode or "Pacman" mode. It can also display the date, including the day of the week and the temperature.
Another catchy function is to show a personalized message (e.g. "Happy birthday"). Wise Clock 3
can be also used as an alarm clock, as a scoreboard or as a countdown timer. To see the other features, please check out the "User manual", the last step of this instructable.
