I made him in year 7, when we first learnt how to use sewing machines @ GWSC. He is complete with 2 red LED eyes and a green LED beak with an internal buzzer. The design was modified from a sewing book and the internal circuitry is just a normal wire circuit without a circuit board. The wings have home-made press switches, which activate the LEDs and buzzer. They're just 3 cardboard pieces, two with foil and the middle with a large hole in it so when you press the cardboard together the foil contacts each other. He is powered by love and a 9V battery attached and hidden by velcro-lock opening.
Definitely visiting this sign the next time I'm in Canberra:
And if a geohash ever lands there ... ;P
