I will be in San Francisco this Monday afternoon, and am looking to meet up with some local hackers interested in having a look into the future of light. Arkalumen is a bootstrapped startup founded by an exceptional electrical engineer and hardware hacker (no, not me). I am in town for a cleantech conference and would love to meet up with some interesting folks. Anyone interested?
I'd be interested in a demo if you manage to round up a crew of people. If you're around for a while, or plan on coming back, you might get a better response doing a demo down at Tech Shop. http://www.techshop.ws There are more hardware hackers down in the valley than there are in The City.
This is a very short trip I'm afraid, and short notice too. I will be in San Francisco on Monday afternoon Sunnyvale all day Wednesday. If I get enough response I can arrange a meetup in either location.
I am not sure I know enough about your LED Christmas lights to be helpful, but we are working with newer (and orders of magnitude brighter) lighting-class LEDs which are not really the same thing. Our startup's core technology resides in low-cost embedded intelligence, and multi-channel control of high-power LEDs.
FYI, there isn't much info on our very basic website as we have been in stealth mode. For more information, here is a link to a brief describing our technology and it's applications: http://www.scribd.com/full/13501981?access_key=key-tdquqebl0...
There is also a video demo of our lamp in action available here: http://www.youtube.com/watch?v=x4GnC_1LbsE&feature=playe... (Our light is featured at 5/7min into the video)
