Saturday night: husband spent a long time on-line researching some of the new initiatives he'd seen.
Sunday morning: he explains to my son how we can wire up the computer to a circuit board and control lights from there. They can come on and go off as we decide. Furthermore (and here's the scary bit) this technology can be extended from just the little bulb that is connected to the whole house.
My son's eyes lit up.
We can set it to be voice sensitive. Walk into the room, say "ON" and the lights come on, "OFF" and the lights go off. We can create a scary burglar alarm. We can control the DS so that it won't work at certain times (son not necessarily quite so happy about that!)
"Daddy, I've been thinking about the lights."
"We can set it up to control other things as well, so the washing machine comes on when we want it to," he says.
"Yes, and we could use sensors so the dishwasher goes on automatically when it knows it is full." My husband is encouraging this thinking.
And now my son gets quite excited. "And we can use it to control robots that will do the work for us. Such as hanging out the washing and folding it away."
Since when has my eight year old had any interest in the mechanics of washing? Oh, I get it - this is to try to get mum on his side.
"And this will save on electricity, only being used when we want it to, and so we'll have money to spend on food."
[I hasten to add: despite the credit crunch I do buy food. And feed it to them. ]
