I have a lava lamp, its neat, but lost its appeal after a few
weeks, same color, always the same color. What if the lava
lamp, instead of just a bulb, had a bulb, thermometer, and
regulator, to keep a constant temperature. Ie. too hot, dim
light, too cold, brighten light. Simple. Remember
those
little
things that go through a series of colours when you warm
them? Same principle just applied over a different
temperature range, and well, the lava lamp.
There could be two kinds: normal, and flowing. Normal
would
just stay at a constant temp, and the "lava" would shift
depending on how hot it is, red-blue going up, green-yellow
going down. "Flow" would have a wider temp. range to
change
the lava's color, the temp regulator would slowly shift up
and
down, maybe every 10 min, and the lava would constantly
change, slowy into another color, less variation, no boring
same color. I could have a fireplace made out of one of
these.

You could put that liquid crystal
temmperature sensing stuff in the wax |
|
| |
link please to some type of "liquid crystal temmperature sensing stuff" |
|
| |
It's the stuff they use in cheap
calculators. if you rub the screen it
changes colour |

I understand what [schematics] means, see link |
