


Electroencephalogram (EGG) to measure brain
waves
Detect and use conscious control of electrical signals
Interpret brain waves into a control system
Adapted from
www.brainstatetech.com

Produce a three plus dimensional controller for
widespread application

Create a brain wave
monitoring circuit.
2/5/10
Obtain 2 different
consumer EGG
controllers (2 of each
type). 1/13/10
Determine placements
for electrodes that
allow for conscious
manipulation of brain
waves. 4/30/10
Open up one of each
type and identify all
necessary signal
processing
components. 3/12/10
Combine electrode
placement knowledge
with RC controller for
demonstration.
5/12/10
Modify output of EEG
controllers to
manipulate and RC
controller. 4/30/10

One dimensional
Controls a fan that controls the height of a ball
Requires training time
Priced at about $100
Reversed engineered to see how they work



Interprets beta waves
Uses one electrode on the
forehead and two
references behind the ears
Uses an algorithm to
control the fan


Interprets fluctuations
in brain waves
Uses two electrodes on
the forehead and two
references on the ears
