Well, these Fibonacci displays really turned me on last year. I really had to make one by myself!

Fortunately, @Jason_Coon provided source code for his creation. I used that as a basis, thank you Jason!

@Jim_Bumgardner developed some very nice animations with his incremental drift algorithm. I implemented that and added our colortable shift mode to that and the result is a very nice animation. Almost as nice as @Mark_Kriegsman 's colorwaves! At least I’m almost sure about that :wink:

You can find the Arduino source code here: http://coto.homenet.org/fibonacci.zip

One more thing…

If you want to play around with a Fibonacci display, but don’t have one yet, here is some processing code that serves me quite well exploring new ideas: http://coto.homenet.org/fibonacci.pde (you need the processing environment available for all major platforms here: https://processing.org/)

One more thing…

You probably need palettes. @Mark_Kriegsman made the famous paletteknife. http://coto.homenet.org/paletteknife.py Here have a Python tool to download all (or just the best) cpt-city palettes and make a large palette file for the processing Fibonacci sketch as well as for your FastLED sketches. It filters too dark and too large palettes, but you still get almost 4000 good looking palettes!

Feel free to use all that code however it pleases you (read: no annoying GPL, no license whatever, just public domain) and have fun!

Fabulous! Great display.

You’re most welcome, thanks for sharing your contributions as well. Looks great, I really like the frosted acrylic, the animations, and the scrolling text.

Looks GREAT – and I love the mapping and text, too!

I am curious to know how you make the holes? Are you using laser cutting or CNC? Do you have a file that lays this out? I am just doing research now to figure out how to do Fibonacci spirals and would be great to not have to figure it out and start off with a template to work off of.

The holes are manually drilled. 100 holes. Don’t ask! :wink:

Here you can find a processing sketch to generate a PDF which you print and use as a mask: Processing sketch to produce fibonacci faceplate · GitHub

How to put the LEDs, so Jasons and my sketch will work out of the box: https://photos.google.com/share/AF1QipNMbXmLbqoGXKTdy2P7uu9c0Q6VIj6W49K7ITw3DsqOMquoQ2Gg6zDxBzYWA4M8gQ?key=ZEdNSlJILTZHaTFGTmZmVzBzNEN1M2g4eG1pbUF3 Otherwise you have to make you own mapping arrays for spiralarms patterm, noise pattern and xy mapping.

I have a CNC machine and am planning on building out a large scale type version of the fibonacci pattern 2’x2’ at least maybe even 30"x30". Thanks for sharing the .pde file, I think I can modify off of that to create what I want and then import the .pdf into V-Carve to create the pattern I want. Thanks for sharing!!!

With a little knowledge and affort you could export G code from processing for your CNC machine. >:-)

Certainly could. However, I have ruined enough material on my CNC because of my own errors, think I will stick with the purchased software. Focus my efforts on coding patterns :slight_smile:

Here is another piece. Basically going to do something similar to this one but with fibonacci…

Sounds cool, Justin, can’t wait to see it!

Thomas, I think this is great! Thanks for providing the source code for Arduino and Processing (yet another powerful tool).

Now I want to build something like it to hold me over until the Christmas season.

Where do you buy/source the frosted acrylic?

12

There is a small company near me, that produces very nice stuff using plastic (including acrylic) and that is so kind and let me dive their dumpster :wink: http://www.carlthomas.de/

But there are companies, that sell sheets of acrylic in every thinkable size. Just look around in Amazon. Drawback: not that cheap.

http://www.estreetplastics.com is a great site for online.
