Short build-lapse video of building up the front panel “matrix” used in BinBoo. This isn’t a true LED matrix. Instead it combining all of the LEDs into a common Anode, since the Cathodes are all controlled by individual outputs of the TLC5940.
I decided to wire up 16 LEDs, even though a binary clock only needs 11 or 12. This gives some flexibility to other uses for the box, like a random sci-fi computer pattern.

The DS3231 is a Precise Real-Time Clock from Maxim. It requires almost no external components and is temperature compensated. This chip solves some of the RTC issues associated with the DS1307. This Arduino shield will make it simple to add a RTC to any project, especially one where lost time is not acceptable.
