Ive been watching some videos on youtube about homemade lucid dreaming masks , but they don't really go into very much detail on how to make one.

I was just wondering if anyone has successfully made one of their own, or does anyone have a link to a tutorial on how to make one?

They don't seem like very complex devices , and from some of the price tags associated with some devices like the nova dreamer , they seem a bit overpriced.
