I plan on posting all of my plans and code on-line with instructions to help you build your own. I'm calling it "Eclipse Clock" because I think it looks more like a solar eclipse (and I didn't want to steal the name). Here's the part list I'm using;
- 1M Neo-Pixel strip
- Arduino Micro
- DS1307 RTC chip
- 32.786 KHz crystal
- CR2032 lithium battery (and holder)
- push-button switch (N.O.)
- small Cds cell
- 4 10K Ohm resistors
- 1 1000 uF capacitor
- 5v power supply (4 amps ideally, more on that later)
The clock will consist of an strip of LEDs shining sideways out of a round case. They radiate outwards and end up reflecting off the wall. There is a single pushbutton for setting the clock and changing color scheme between some presets. A real-time clock chip keeps accurate time. Hours are represented by 3 lit pixels, minutes by 1 lit pixel and seconds by another lit pixel. Themes can change color values of these as well as use a separate background color (which could let you have a fully lit ring with dark values for hours/minutes/seconds).
Source code will be on github.
More in a future post, but that's where I'm starting!
