Eyeball Light

thingiverse

The Eye Blazer was crafted using three distinct sizes of cardboard rolls and a lengthy piece of nylon hose scavenged from a trash can. The tubes were severed in half utilizing a jigsaw and then painted. Printed spacers secured with hot glue keep the halves in a concentric arrangement. The printed nylon hose holders are zip-tied to the smallest diameter tube. The nylon hoses measure 10mm in outer diameter, 8mm in inner diameter. Each Eye Blazer measures 635mm in length, 635mm in height, and 317mm in depth (25"x25"x12.5"). Four lengths of bright blue LED tape are positioned inside the eye, shooting inward, reflected by the blue paint and glossy finish. Four lengths of intense white LEDs are situated on the outside of the two larger tubes, diffused by hemisphere-shaped diffusers printed in translucent "natural" color filament. Both Eye Blazers have switches that turn the bright white LEDs on and off. I keep them turned off most of the time; they're extremely bright! For the fairy lights inside the nylon tubes, I employed a clever tactic: soldering a length of wire with four 17-led parallel segments, then attaching a 10 ohm resistor in series. This allowed me to run the 2.5V fairy lights at 12V. For my next Eye Blazer-style light, I'll utilize more salvaged tubes - complete cylinders this time instead of hemispheres. I'll also use individually addressable LED tape for the diffused outside lights, connected to an Arduino Nano or a Digispark.
