[...] a
motorized USB "Aquarium" [...]
Whule I can see the point of taking power
from the computer for an
interface converter, keyboard, mouse, something like that, wouldn't
it be simpler if devices like the aquarium, light, etc had their own
mains adapters?
As regards a light, I use this simple device containg 4 components. A
couple of AA-size primary cells, a tungsten filament lamp, and a swtich.
Even I can keep one of those going :-).
WOW, you really cling to the obsolete technology! Filament Lamps! AA
batteries, and alkaline too no doubt... Its all Lithium power cells and
Xenon or LED bulbs these days ;) I bet you're still using some version
of Edisons carbon filament incandescent bulbs in your home too, even though
compact fluorescents cost less than $2, last 10 - 15 times longer than your
60 cent incandescent bulbs, and use 1/4 the electricity (soon to be obsolete,
though, when the cold cathode bulbs start appearing in higher wattages).
