- First to note....sensors for detecting movement I have not really heard
- of, but I do know that most brainwave monitor circuits can be used, set
- to the Alpha mode. Plant two electrodes either side of your head on
- your temples, and when you are in REM you generate large quantities of
- Alpha, which you can use to light lights, sound sounders, or in one
- circuit I saw , when you are dreaming it gives you a ~ 90v shock
- (harmless) through your leg....this is supposed to make you become
- a little more conscious and stimulate "Lucid dreams". However
- any electronic circuit like this *Must Be Powered By Batteries* as any
- mains powered equiipment with a fault could kill you! ... Connecting to
- a PC analog port/digital port is fine ... as long as it is opto-isolated.
-
- If you can get hold of a magazine called "Electronics Today International"
- there was quite a lot of EEG/Brainwave/Dream machine stuff over 1987-1989.

- Have fun
