Luminescence

A joint project with the Handweaver’s Guild of Boulder County to support their 50th anniversary. More info here.

Retro Desklamp


mod_lamp_lo

A re-purposed 60s-era cork and glass lamp with about a hundred 3528 warm white LEDs and my touch dimmer.

Night Light


lasernightlight2_lo lasernightlight1_lo

A 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 hues.

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


mix6_1 mix6_2

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.

Rear Projection

A 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 surface.

Egg

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 partner.


70s Retro

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 desired.


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



orig_blinkie

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.
