NY Times Article on Solid-State Lighting
The New York Times published A Glimpse of a Future in a New Kind of Light today, an article that says semiconductor lighting will find its way into the home and office by 2007.
The eventual result, the experts say, will be savings of billions of dollars annually in energy and maintenance costs and a revolution in how people use lighting in homes and offices to influence their moods.My favorite quote? Fred Oberkircher at TCU says, "I'm waiting for the day when clouds of light float across my ceiling." Ahh, time to crank up the old video camera and go shoot some b-roll.
"We are not talking about replacing light bulbs," said Arpad Bergh, a former Bell Labs researcher who is president of an industry trade group working with the government to promote the new technology. "We are talking about a totally new lighting industry."

Dutch Graduate Student Discovers Two-Tone OLED
A grad student working in a Organic LED lab in the Netherlands discovered an interesting feature in some OLEDs he was given to test:
While Dr. Hofstraat is still studying the fundamental nature of his two-tone O.L.E.D.'s, making them change color could not be easier. The color changes from red to green (or, in subsequent models, between any two primary colors) when the direction of the electrical current running through it is reversed.Red Light, Green Light: A 2-Tone L.E.D. to Simplify Screens

Semiconductor Lighting
I just woke up from a dream where the last vignette was a green lighting display featuring artificial palms that employed semiconductor lighting-- LEDs.
I really like this term. Every time you say LED to someone you have to explain it anyway, so why not talk about semiconductor lighting instead? It's more elegant.
Besides, there is a terrible assoiciation with lead (Pb) based things in the household that should be avoided, eh?

Four LEDs, 9V battery, film canister.Jack-O-Ledtern
Psydeshow Roductions is pleased to announce our first commissioned glowbot, the Ledtern, seen here as part of a Jack-O-Ledtern.
The Ledtern will light up any small space, without generating heat, and without excessive battery consumption. In fact, the 9V battery in this pumpkin will keep it lit for weeks.
You can make your own, here's the recipe:
