"Mood Loop" by Andy Flind

Everyday Practical Electronics/ ETI August & Sept. 2000

EPE has previously explored the principles of generating
weak magnetic fields at "brainwave" frequencies, which are
thought to encourage mental states of relaxation, creative
mental imaging and even sleep. Previous projects used a tiny 
locally-placed generator.

The EPE Mood Loop is a PIC 16F84 powered version produces
an increased effect by delivering amuch larger current into
an inductiv eloop system which may be placed around a small
room, to permeate an area of approximately 4 metres square
with the field. Switchable Alpha, Beta, Delta and Theta ranges,
driving a power amplifier.

The latest version of the software is available from
