Night Cavity #2 : New Sculpture
This is my latest sculpture, its mixed media/assemblage art. Mounted in a 8x8 deep edge canvas. The "organ" part the glows is made of moulded fabric/paper and acrylic paints. The illumination is provided by a high brightness LED. This powered by a 2xAA batteries, connected to a home made circuit, which is a light-dependent resistor and a "Darlington pair" of two transistors. This detects when its dark and switches on the LED. The batteries last weeks and it looks quite different at night to during the day.
