Hi all,
I've been thinking about this product for quite a while now, and I may
be wrong but it
could be a great way to globally save electricity & maybe even lives.
In an earlier Silicon Chip article someone posted a simple soldering
iron timer that used a clothes dryer timer. I thought the idea was
good, and scavenged a timer from the local recyclers
but have yet to do anything with it.
Anyway, this led me to think of something that may save a lot of
electricity and also offer
a safety aspect.
How about a generic countdown timer?
This (mains supply) unit would have to be simple due to it's most
likely use for forgetful or elderly people. It should also have a
rotary type input to make it easy to use
From my own perspective I also have a lot of 'wall warts' (DC
supplies) that I leave connected and using power. Add the TV etc.
also.
Of course if this is a good idea then I've pretty much screwed myself
for making any money out of it by posting this message, regardless...
As this is an electronics forum I'd like to ask your thoughts on how
to best implement
this idea.
1. Clothes Dryer control. Easy to make and inexpensive, but not
'scaleable'. ie. the 'product'
should have different 'templates' to allow for a different range
of times.
2. Microcontroller and RC servo. Limited feedback due to pot, but
maybe viable
3. Microcontroller and Motor-driven Potentiometer ie. remote volume
control. Maybe more expensive again.
Anyway, just thought I'd throw this out as an idea. Probably one that
someone else will patent
and make a stack of money off, but I think this could really save
power consumption.
