Hey all,
I need to build/buy a small, cheap, battery powered system which will
allow me to turn on/off another battery-powered apparatus remotely.
I have a small battery-powered radio which is behind closed doors.
The radio runs off a single 9-volt battery. For reasons I won't get
into, I can't easily get to the radio at all times of the day to turn
it on and off. Ultimately, as it goes now, the radio remains on at
all times, basically until I can get to the radio at the end of the
day to turn it off, or until the battery dies and I go back in to
replace the battery thus starting the cycle all over again.
I was wondering if there was a way for me to create or buy a remote
receiver (I guess it would need to be RF or something similar, since
IR won't work through the door) which could listen to a remote signal,
and switch on/off the radio circuit, alternately cutting
off/connecting the power supply.
Ideally, this receiver would be battery-powered, and would not draw
much power at all (so it could stay up and listening for days or weeks
on end). It could draw from its own separate battery. And, it would
need to connect to the radio circuit so the radio could be turned "on
and off" appropriately.
Sound like something easy or cheap?
Thanks,
James
