Pong Clock
A fun clock designed and coded by Nick, with only minor modifications. The score is the time with hours on the left and minutes on the right, advanced when a paddle misses the ball.
Multiple display options are available. I added a peizo beeper, Daylight Saving hardware switch, an extra button to directly scroll through the display modes, and a radio module to synchronize multiple clocks to one master.

How it's done: Arduino Nano, DS3231 RTC, Sure Electronics LED display boards, nRF24L01+ radio transceiver for synchronizing to my GPS clock. Awaiting appropriate enclosure.
Some of the other built-in display modes.
