Hi Nicolas,
It looks great.
I also made something like this once (LED tube with "smart" Dim function).
After seeing your video, I feel like making something like that again.
Great that you take the trouble to share it.
Keep it up and especially post it here on the forum so that other users get as excited about it as I am.
Bye the way, I have built in a rotary encoder in the base to be able to dim the LED strip.
See this result and this one.
