I have trouble with headphones too :P

how reliable is the rem pulse method ?[/b]
I'm honestly not sure. We would need to test it I guess
And not just one subject, you'd need to test multiple subjects

i know i build a kvasar and junked it... *it took me one month to convince the guys at hamamatsu that i was an electronics company and i needed two samples of the IR sensor... and i ended up breaking the pins on both samples after some 3 weeks of trying to get the ir led and the sensor placed right... it picked up blinking, but not subtle rem movement (IR light is not dangerous for the eyes btw)[/b]
After all that ... hahaha

anyway... maybe we could start by finding a way of hooking up one of those wristwatches to the computer and figuring out how the data acquisition would happen (how the monitor send the information) and just how reliable rem detection would be (which would involve i guess sleeping with wires attached to your hand for a few nights)... then go on with the research ?

Yep. The problem I see is that its not gonna be easy to figure out what the wristwatch (or whichever device we butcher) pulse monitor sensor interface is like. Power, inputs, outputs etc
I was trying to source the sensors, but damn it's hard to find in my country
Another problem I face is that I'm not an electronics whizz
I have friends and work colleagues that might be able to help though

(i'm really interested in this project because i've lost all confidence in ir detection)[/b]
Is this because of the IR sensors that weren't sensitive enough?
There's a chance that IR detection is more reliable :/
I've been thinking more about the benefits you could get from the pulse idea
- We'd be able to activate it in slightly deeper sleep, etc ... possibly inducing lucidity at steadily lower levels of sleep. Maaybe.
- You end up with nice analog output data, that you can use to determine how healthy your sleep is (knowledge is power)
- It's more comfortable on your hand, than on your face. Perhaps a wire on your hand won't be too bad?
On the negative side... 1. Complex to work with and 2. A little more costly (I think)
When I get money in again, I'll try get myself a cheap finger pulse meter, and butcher it
