PrismaChron Color Clock

Myself and the other fine gents at Maniacal Labs just finished a new, Arduino compatible, clock kit called the PrismaChron. The display consists of three RGB LEDs, one each for seconds, minutes and hours. As each value progresses through time, its LED slowly fades through the spectrum from red to violet, and everywhere in between. It's easy to build, has a built in RTC for accurate time, and has both FTDI and ICSP headers for easy upload of new/modified firmware. We're trying our hand at community funding and have started a fundraiser over on Tindie: https://www.tindie.com/products/ManiacalLabs/prismachron-clock/

We’d love to hear what you think!

Cool concept!

Except for the colour blind, => you should include the intensity to solve that,
Is the hours 24 based or 12 based?

It's 24 hour based. Made for a broader color range.
We've actually thought about making a "Monochrome PrismaChron" at some point. Just 3 regular LEDs and varying intensity. We could do something similar with the RGB leds though :slight_smile:

you could add

  • a pulse for counting seconds with the seconds LED (e.g. 0.1 seconds off)
  • a minute pulse for counting minutes with minutes LED
  • a hour pulse for counting hours with the hours LED.

Now it is rather difficult to count seconds (etc) with the continuous colour. The above scheme could solve that!
