My favorites are the solid state micro-machined accelerometers from Analog
Devices as can be seen at:  http://www.analog.com/pdf/preview/ADXL105_a.gif

They have low power consumption (2mA), and are small (surface mount) and can be
used for tilt *and* vibration with different filter models; also they are cheap
(even free if you ask them nicely for a couple of samples).

Hi All:

For the cats pajamas of tilt sensors, take a look at www.schaevitz.com.
Sadly, the single axis tilt sensor I want  is $135.00.  It offers a
ratiometric output, 0.5ma draw@9vdc, threshold of +/-0.001 degree,
linearity to better than 1%.

I have absolutely no practical use for these in my toys, but boy would I
like to be able to justify one (or two) ;>)

Hi David ... There are two types of switches commonly available.  One
is a small plastic box with a metal ball inside ... when it rolls in
one direction it touches two contacts and closes the circuit ... tilt
it the other direction and the ball rolls away from the contacts.  The
other type has a bead of mercury in a glass enclosure and works the
same way.

Have fun,

Ayyone made a tilt sensor yet out of an old switch or an old thermostat? • It
wouldn't be a linear function. It would be like a touch sensor, reporting • if
the tilt angle was reached.

Just an idea....
