I'm trying my damndest to investigate alternative methods of detecting REM.
In theory, I'm doing well. In practice, its damn hard to find the right sensors for this stuff, without paying big money for the displays and equipment. I just want the damn electronic sensor

Does anyone have ideas on how to source finger sensor electronic components (ECG), finger oximeter components, galvanic skin response (GSR) components... or anything along that line?

I have a kickarse idea for a novadreamer replacement, but I guess the above question should pretty much tell you where I'm going with this...

PS
The reason I want to do this, is 'cos LD has to be my LIFE before I get decent consistency of them. I would like to have periods of LD relaxation, while still enjoying LD's with no effort. I do believe in learning how to attain LD's naturally, but I have a life outside of DV sometimes
