Maybe I sounded a bit blunt, (and sorry if I did!) but rest assured I wasn't trying to dismiss the value of your input
My concern is more about the fact that DYI poses some risks especially for people who tend to use these devices without proper knowledge about their possible side effects or proper management of the equipment. Because the technology itself fascinates me as much as the next guy: there's is a thread hidden around DV which talks about neuro-modulation and it's possible use on lucid dreaming.

Maybe in a few years we will all be using it ^^
