IP over Fatness

Something I've seen a little of lately, if you had some Bluetooth or internet-enabled weighing scales, you could exert a force on the scales to transmit a reading. You'd have to check and see what kind of accuracy you can get and how much force you can generate with Meccano. You could place one of two weights on the scales for 0/1, or if you could generate the force mechanically (and accurately enough) you might be able to get 4 or 5 bits per reading. A screw and a spring might work, as long as you can lift it clear of the scales so they can calibrate on power-up.

I like Bluetooth for this application because it adds lots of lovely layers to the stack diagram.
