A re-purposed 60s-era cork and glass lamp with about a hundred 3528 warm white LEDs and my touch dimmer.
custom night light built in a laser-cut enclosure. Red LEDs
illuminate the rear edges and top surface to match the red
wall it is plugged into. A single RGB LED illuminates the
front using a slowly changing random fade between different
Pill Bottle Light
Twelve 5050 (3-chip) LEDs provide the
light source in a pill bottle shaped like an Edison light
bulb placed in a Mexican star light. Dimming provided by a
custom 12VDC touch sensitive dimmer prototype.
Mix 6 is carved alabaster about 15" x 11"
x 9" running the rainbow6 program. I originally wrote this
program for Ilya Makedon who creates LED artwork and owned
the Labyrinth gallery in Denver. The main idea behind Mix 6
was for a LED sculpture to show multiple random colors at a
time. rainbow6 allows for a wide variety of pseudo-random
color patterns. I aimed the red, green, blue, white and
yellow LEDs so that these color patterns would play out
non-uniformly across the surface of the piece.
Blown Glass Ball
The glass was blown by my daughter and
sits above four LEDS (red, green, blue and yellow)
controlled by the rainbow2 program. The idea was to refract
color off the air/glass phase changes inside the glass
globe. rainbow2 is a simple fader with 16 different modes
but primarily oriented at fading through the rainbow of
colors at various rates. I personally like sculptures that
change color very slowly so a casual observer doesn't
realize the color is changing until looking at the
sculpture much later.
gift for a friend controlled by the rainbow2 program. I
used silver jewelry wire to mount the LEDs above the
electronics enclosure. Colors fade across the polished
Agate slab. There is a beautiful interplay between the
partially mixed LED colors and the irregular agate
The egg is a lit "found art". In this
case an alabaster "egg" lit with 12 red, green, blue and
yellow LEDs controlled by the rainbow2 program. It doesn't
really show in the images but each "segment" of the egg is
slightly different which changes the light slightly
resulting in a beautiful object. The egg was a gift for my
The 70s Retro light is another "found
art". I found a square glass mood light on top of a cork
base at a garage sale on Saturday morning. It is lit with
55 red, green, blue, yellow and white LEDs shining through
a couple of different diffusers running the rainbow5
program. This program cycles slowly through a color
spectrum about each half hour. It has a set of push buttons
that allow setting the light to a specific color if
Jewel case Nightlight
The Jewel case nightlight series runs
rainbow2 using a single RGB LED and two Yellow LEDs in a
small ring case. I like the way the light plays off the
plastic facets of the ring box. I overdrive the LEDs and
the device is amazingly bright.
A Harbinger of my future
During the summer between my senior year of high school and freshmen year at college I was fascinated by electronics systems, such as spacecraft, that once built, could never again be touched, modified or fixed by a human. They would just run on their own until some failure. Since I couldn't build space faring devices I would build a circuit and encapsulate it in epoxy resin. That way it was impossible for me to ever get to it again. One item that still runs, some 30 years later, is a set of 4 LEDs driven (with inverted logic) from a 7490 decade counter TTL IC with a 555 oscillator. I have had this device running constantly no matter where I have lived.
