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... ?
