This "Wise Clock 3 kit" does not include the display. To build the clock, you need to provide your own 3mm 3216 display (about $30 on ebay) and make your own enclosure.
"Wise Clock 3 complete kit", which includes the 3mm display and the laser-cut enclosure, is offered for sale here.
Now that I have a version of the software working well with Wise Clock 3 board, I can offer a "Wise Clock 3 kit" for sale. This board is designed to plug directly into the 3mm 3216 LED display from Sure Electronics. The software is pre-loaded onto the microcontroller chip.
Note: Wise Clock 3 board can be connected to the 5mm 3216 display only through the ribbon cable that comes with the display. If you insist on using the 5mm display (which I do not recommend), you will need to replace the right (looking at the top/component side) connector with your own 2x8 male header.
This is, in summary, what Wise Clock 3 can do (Edit: the software is upgraded periodically, here is the latest):
- display the current time, retrieved from the highly accurate real time clock that is DS3231;
- along with the time, display quotations retrieved from a user-editable file on SD card;
- display a personalized, user-editable, message, e.g. "Happy birthday John", "Happy Valentine's Day my dear love";
- display the date and temperature;
- display the time as a Pong Clock;
- sound alarm at the specified, user-settable (through buttons), time;
- set the time, date and day of week from buttons;
- enable/disable the display of personalized message, date, temperature.
