A simple timer with a ring to count down. The build is done and I hope I took photos. I still need to work on code which should be reusable in your own projects
Code will be ip on GitHub when I have something working

Bill of materials

  • Seeed Xaio
  • 24 LED ring light ( Not an Adafruit Neopixel ring but only because I couldn’t get one with Amazon gift cards)
  • 2 momentary switches (part of a donor board. It is mounted under the diffuser so that the buttons can be pushed but are hidden. 

External build

  • The LED diffuser is part of a opaque folder with mirrored sticker stock covering the middle.  I tried just paper, card stock, and half a clear plastic ornament ball.  None of those results looked as nice. 
  • Underneath the LED ring is a clear plastic ring salvaged from a roll of large format printer paper.  This was what everything was mounted to.  It was wrapped with more mirrored stickers to cut down on light leaks. 
  • The colourful outside was made with Hey Clay, a foam clay for kids.  It is easy to mold and clean up. It dries soft but shrinks a significant amount.  This is why it’s pulled back from the diffuser. 
  • Not shown - lots of hot glue.  Seriously, it was a lot.

    For anyone following along at home I've added the code to Github.  So far it's just a few visualizations I've coded up to test and decide what I wanted it to look like..

  • Q: Why is it called squishy?

    A: The clay foam outside ended up almost like a stress ball and the way the buttons are mounted under the diffuser means you have to squish on the top to press them.

    Sorry, no mystery here

    To anyone looking for Hey Clay that isn’t in Canada to buy it from COOP….

    Good luck. 

    I just used it because it was handy and good enough for a prototype. 
    if you have the cash just use Sugru for better results.
