BEAMers,
I recently came upon a page with a vertically diving bot. I really liked the
idea. The person proposed to put it in a long glass tube filled with water
in his living room as a piece of work to admire. I liked that idea too :). I
propose to build one and I propose to build one in an inverted test tube.
The solar panel (perhaps some of the very small 0.5 volt, 3mA cells in
series) will be in the top where it will charge under a lamp or sunshine at
the surface of the water level. The cap will be below it with a solar
engine, probably a 1381 type and the pager motor will have a shaft extending
out the bottom test tube plug with a propeller. I intend to use metal
washers of equal diameter to the test tube to achieve just above neutral
bouancy. I want to make it in as small a test tube possible so that I can
put it in a large graduated cylinder on my desk as an active ornament.
What do you think?
Greg
