Having some fun with my WS2812B and MSGEQ7 Spectrum Analyzer.
This time trying some code with the FastLED Libray.

That is super Willy! Nice pattern variations.
Any build photos? How many pixels per meter on the strips you used?
@marmil Thanks for your comment.
I do have some pictures of my build I may post some of them later.
I basically used Denis Lanfrit’s design from his website: http://www.hardwareguida.altervista.org/spectrum-i/?doing_wp_cron=1537138674.6949400901794433593750
My design has more leds per tower. 10 leds per tower with a total of 70 leds. The type of led I used is the PL9823 similar to WS2812b.

The whole set of leds are treated as a single led strp.
Here is short video with pictures of the Spectrum.

Oh, you didn’t use LED strips! (I didn’t actually click through on the link you provided.) Nice. You got some good soldering practice. 
Super nice !!
