Invention isn't some impenetrable brand of magic; anyone can have a go.

Do what gives you a buzz.

All inventors, they say, are a little mad. I reckon that only completely sane people are willing to admit they are slightly crazy.

I was on automatic pilot; ideas for gadgets kept coming, fed by a force of energy flowing through me and around me.

A good idea turns every cog in your mind, making you scared of bed in case the whole machine grinds to a halt.

That was the Alka-Seltzer moment, the moment when the tablet hits the water and begins to fizz.

As long as you've got slightly more perception than the average wrapped loaf, you could invent something.
