Neet website, thanks. It looks kind of too complex for me but maybe I will give it a shot. I have had some interest in that nova dreamer but it is just way too expensive. Electronicly it isn't even all that complex so why do they price it so high?
Read what the inventor of the device has to say about it here:
http://www.improverse.com/ed-articles/craig_webb_1997_may_dreams_foundation.htm
- go to the section where he answers the question "Do you use the Lucid Dreaming technology yourself?"
I've been wanting the Novadreamer for a long long time, and never could afford it. According to this webpage (the only site that sells it), it costs £299.00 / $493.36 (see http://www.lifetools.com/acatalog/Awaken_In_Your_Dreams_with_Lucid_Dreaming.html#a34).
I've found this webpage (http://brindefalk.solarbotics.net) that has a DIY project to construct a Novadreamer-like device. The parts cost about $50-60, and requires a basic knowledge of electronic assembly (and a multimeter).
Technically its for LD training, but it would be very useful in OBE training.
Just a FYI. I make no profit from it one way or another (especially as it is Do-It-Yourself).
