Thread: Magnetic field viewing film - bistable, high resolution
face picon face BY : M. Adam Davis email (remove spam text)

I thought a lot of you would get a kick out of this:


Magnetic field viewing film - green plastic turns black where a field
penetrates the sheet.  High resolution, bi-stable - you reset it by
swiping a magnet across the surface.

Relatively inexpensive - 1 square foot is $40.  A 3"x3" patch is
$4.50.  I could see using this as poor man's e-paper - perhaps making
a high resolution line solenoid array, drawing the 'paper' through,
and using it until it needs new information.  Different from the
magna-doodle ( http://www.howstuffworks.com/magna-doodle.htm ) but
similar in several interesting ways.
