Robo-Rooster has a hard drive actuator arm for a head, LED Christmas lights for eyes (they light up), and a CPU fan mounted on a tube from a ballpoint pen. A 5V power supply drives the fan and eyes. He has wings and a tail made from hard drive and power supply connectors, and a grounded AC plug for a body. His legs are made from wire hangars.
His son has a laptop hard drive arm for a head, and a body salvaged from the gas tank of a broken toy motorcycle.
These creatures were built to the exacting specifications of my 9-year old.
