I'd like to put a strain gauge on my bedrail to allow my alarm clock to sense whether I've gotten out of bed. Obviously, high accuracy is not critical. Digikey doesn't seem to have anything under ten bucks, which is a lot to pay for what seems like a bit of etched foil.
Am I missing something, or is that really as cheap as strain gauges get?
