Hmm, so it would be wishfull thinking to try a IR module set up like this:
**broken link removed**
And try to fine tune it so that the current change is measurable when the person closes the eyes ?
I then want to from those different changes make a second circuit, propably with a PIC processor, (I have yet to figure that one out but that won't be a problem) that will notice if the current is low (closed eyelids) for t seconds.
Do you think the current change is so small that it won't be measurable?
