From previous projects, I have a special place for wood. It's a beautiful natural material which is easy to manufacture and has a stunning aesthetic. I think this would be best for the clock base.
In terms of the light, I have researched into LED's, OLED strips, and NeoPixel's. LED's would be very difficult as they require resistors and wouldn't be programmable the way I want them. LED strips are too spaced out, also not programmable the way I want. OLED's are stunning, but very expensive to obtain. They create a very blended light source, but again I couldn't see any that were programable. This brought me to Neopixels.
The NeoPixel ring would be pretty perfect if it came in a much bigger size. After a lot of internet surfing, I came upon these NeoPixel strips from Adafruit. With these, you are able to control each individual led from your code. They come with two different spacing options. For my design I think the 144LED per meter would be best.
There was a question on the website that was very interesting about the amount of pixels you can use.
Q: Can I use more (or fewer) than 144 pixels?
Certainly! But there’s an upper limit of 170 pixels. This is the maximum that can be recorded in one SD card block (512 bytes). Going beyond this would require reading two (or more) blocks and would halve the speed of the entire system…you’d have to move at a snail’s pace when taking photos
You’re welcome to hack it up and try, but the code will need significant changes, and there’s no guarantee the Arduino even has enough free RAM to handle this.
To get the data from the website, I will need to get a Raspberry pi that translates the data into code that Arduino can read, and tell the NeoPixle's what to display.
