Subject: [alt-beam] LEM videos now on-line.
Whew, that was too close...
Ok, the LEM page has been updated to include the videos!
(sorry no schematic yet...)
The videos have been encoded with the new RealPlayer G2 codec, and a link for a
free
download has been provided.
The 'Seeking' video shows the rather unusual form of phototropisim that is
unique to
these new multimotor symets. In this video you will see the LEM's reaction to a
moving
light pool. While having no prefered direction of travel, its strongly
phototropic. LEM's
behavior is also strongly effected by the overall light level, and some evidence
of this is
also shown when the light source is moved closer to the RJP.
A second, shorter video shows LEM's logic powered and running with the motor
drive Bicores disabled in a dark room so you can see the timing and sequencing
of the microcore, and its mapping to the Bicore modules.
The 'Seeking' video also has sound, one of LEM's best features is its cool
1950's sci-fi
sound effects when bare gears are used as wheels. Check it out at:
