LED Clock
The LED Clock project builds on the Alarm Clock Project, adding a display of the time by illuminating 24 high-powered LEDs.
The time display uses 12 LEDs for the hour, and 12 LEDs for the minutes, so the example pictured shows 2:50pm (2 of 12 hours in one row, and 50 of 60 minutes in the other).

For a more compact build, the two breadboards can be placed back-to-back and housed in Lego.
5mm LEDs fit exactly into the 4.8mm voids of Technic LEGO. Who knew? https://t.co/RHwetyFMbk pic.twitter.com/VbkFm2GajQ

The project can be embedded in a laser-cut housing to produce an ambient time display, or a Word Clock style overlay can be added, showing the time by lighting up words, such as [It's] [Two] [Fifty] [in the] [afternoon]
