I wanted to create a nice looking Deej volume mixer and also have it show some smooth LEDs when mixing my windows volumes.

Check out the GIT repo with the code and a description as well: https://github.com/b03tz/deej-volume-mixer

Here's a full creation video:

You need 12x5 LEDs on a 144 led p/meter strip: https://nl.aliexpress.com/item/1005005574282373.html

You need 5 linear sliders: https://nl.aliexpress.com/item/1005006614304157.html

Also you'll need some M3 screws, M4 screws and M3/M4 heated inserts.

I got these inserts: https://nl.aliexpress.com/item/1005004870993068.html

And M3/M4 screws from here: https://nl.aliexpress.com/item/1005006034879477.html

But I guess any (fitting) screws/inserts will work!

Also any arduino of your choosing that has at least 5 analog inputs (for the sliders) and 5 digital outputs (for the LED strips). You can also daisy chain the LED strips if you want (the internal hardware board allows for that!)
