The two 1" acrylic balls were drilled to about half their
depth so that the LEDs would just fit in. Two LEDs were then wired up with a 470
Ohm resister and covered in heatshrink. The two wires were spliced together and
connected to a length of two core wire.
After testing, the LEDs were
secured with dab of hot melt glue. The balls were then secured to a 'Bucky'
skull from 'The Anatomical Chart Company'
Prototype haunted house light unit. 3 Ultrabright LEDs are mounted to a small piece of strip board, along with 3 470 Ohm dropper resisters to be able to run from 12V. Connection is via a length of 2 core flexible 'bell wire' . The board is secured in a small PVC pipe end cap using hot melt adhesive. I will probably use bottle caps when I make a few more as they will be lighter and smaller. This one is green and acts as small spot.
