esp32-dali-clock
This is an ESP32 recreation of the "Dali" digital clock where the digits "melt" into one another. Watch a full demonstration on YouTube
Stretch Goal for Sponsors!
:orange_heart: :yellow_heart: :purple_heart: If I get at least 25 GitHub Sponsors for this project, I will work on a vaporwave-style of this clock! Watch this helpful video Vaporwave vs Outrun, What's the Difference? for a breakdown of the differences between outrun and vaporwave aesthetic! :heart_eyes:
About the project
The Dali clock was first written in 1979 by Steve Capps for the Xerox Alto and later ported to the Macintosh. Later, Jamie Zawinski re-implemented an X Windows version called xdaliclock. Jamie's page has a full write up of the history, including a link to a super trippy film from the 1974s that inspired the clock.
My re-interpretation of the Dali clock includes colorful retro graphics and outputs composite video output for any NTSC or PAL television or monitor. Putting it together is ridiculously simple, requiring only two wires. All configuration is done via a web interface YouTube and clock's time is synchronized via the Internet.
More details
This project is a follow up to my earlier project, the [arduino-dali-clock], which used a TFT panel and an external clock module. For my clock, I borrowed the ".xbm" font files from Jamie's work, but my implementation does not share any code with that version. For video output, this project includes code from rossumur's [esp_8_bit] and bitluni's [ESP32CompositeVideo]. These changes are also available in my standalone project [ESP32CompositeColorVideo], which also includes a write up on what bits I borrowed from where.Troubleshooting
