Some people are just crazy when it comes to Christmas lights, and if this guy's tree is just average, the things he can do with it are awesome.
He made a DIY system that allows him to trigger the Christmas lights when he gets a call from Santa, using morse code, or even be giving it a hug. He even took the time to record a dozen videos to explain the behind the scenes of those experiments.
It's not his first attempt at doing this, as he made a similar video last year already, with the detailed process of building the connected tree.
