The lights would be at least 6 to 8 inches in from the outside surface.
Not sure about the light circuits yet. We'd prefer to make up cluster
of lights individually switched but probably the switching complexity
would require that we connect them all together to one switch...

Hey db,
How far inside the ice will you put the lights?
Will the the LCDs be connected by wires
in a circuit to a single power source?

Subject: DC powered remote control switch buried in
block of ice?
We will be making a large ice sculpture (1 ft x 4ft x
6 ft. block)
frozen for 3 weeks with some LED lights buried
internally (the lights
will be powered by lithium polymer batteries (90%
power at 0 degrees)
buried with them).
Without the use of wires running to the outside, I
want to be able to
turn the LED circuit off and on to save power.
What remote control switching technology does anyone
suggest I use?
Radio, IR, etc. ?
This situation is kind of a backwards from the usual
battery powered
remote control device switching a 110v powered
receiving device such as
in TV's and garage door openers.
In my case, inside the ice, a low powered receiver
needs to control a
low powered switch that powers the LED's on and off...
the external
controller outside the block of ice can be battery
powered or 110v.
(Walking up close to the sculpture with the control
device is no
problem....)
The problem I suspect is that the switch's allways on
receiver would be
more consumptive of power than the LEDs I am trying to
switch on and
off.....
Any advice anyone can give me re: the appropriate
technology and
components I might use will be greatly appreciated....
It just occurred to me that maybe some kind of timer
would work rather
than a remote switching capability... ?
