The Wizz Clock was a must-do project. It's very common to see hobbyists creating custom clocks so I just had to do mine. It's basically two 16x24 red LED matrix displays, bought from Sure Electronics on eBay, assembled in a pretty CNC-cut wood enclosure. The russian birch makes a nice constrast with the black laser-cut acrylic panels. A hand-made, acid-etched PCB with an ATmega164P and an RTC displays and keeps time. A FT232RL chip creates a USB connection to the computer to sync the clock with the computer's time and set alarms, up to 3 per day of the week, using the C# application I made for it.
