Jeremy Blum built this Custom Word Clock. It has lots of non electronic parts such as the great looking case. Good thing Jeremy is no longer at Google and is now working at Shaper with use of a wood working shop. We have seen lots of word clocks here in the past but the main thing I like with this design is the LED panel based design. Most designs use either individual LEDs or addressable LED strips to provide the illumination, with the panel method it removes this large headache.
“I wanted to control the whole thing with a Raspberry Pi and Python. Why? I want to be able to use the clock as a platform for Leah and I to do some Python hacking. This word clock functions fine without an internet connection, but using a Pi makes it easy to hook up to the web for adding future features like a web interface to set an alarm clock – future expansion options! ”
