If you have ever been in this position, you know that it is not a fun place to be - my astro toy account is "broke", and I need to sell something to get enough $ to buy >another< piece of equipment...
So I have lowered my asking price by $75.00 -

This is a fully operational self-contained (9vdc), solid state
laboratory-quality brainwave monitor/biofeedback monitor from Edmund Scientific Company; reuseable electrodes and electrode gel are included. Outputs are provided for connecting a microvolt meter, strip chart recorder or oscilloscope. I do not have the instruction manual, but have asked Edmund Scientific to locate one. This unit is no longer manufactured. A GOOGLE search finds 8 references to the Biosone II and they will tell you how to place the electrodes.

The Biosone II monitors alpha and theta brainwaves and indicates brainwave activity either visually by led or by audio tone via speaker or headphones.

Alpha and/or theta brainwave activity can be monitored either
"Proportionally" (by measuring the amplitude of the selected brainwave) or by "Threshold" (in which the amplitude of the brainwave must exceed a variable threshold intensity determined by the user).
With sensitivity set to 100 mv, use "Threshold" to learn to produce the desired brainwave. Once you learn to produce and maintain the desired brainwave state, use the "Proportional" function to train yourself to increase the amplitude (strength) of the brainwave.

The Biosone II incorporates a "Self Test" feature which shows that this unit is operating as designed. Operation is very simple, almost "intuitive".

Selling to help finance CCD camera.

Shipped to your door insured (conus) for <<<was $300.00>>> NOW $225.00

Cost new: more than $600.00

Thanks for looking,
