You go, geeks!
Two years to affordable LED lighting?
More great documentation from NYU ITP. This is my holiday project.
Libelium in Spain is defining this open sensor space and making a business out of it. Good overview here.
CIW had a triumph just before they visited us this month - an agreement with Subway to increase the price paid for tomatoes by 1 cent a pound, thus raising income for workers from $10,000 a year to $17,000. This followed similar deals with MacDonald's, Taco Bell, and Burger King - all of them tough fights.
Look at Day 7 and 8 of their tour blog to see their visit to the Girls Club:
Also see Katrina Vanden Heuvel's column in the Nation on CIW's work.

David Stuart's creation, available on a t-shirt of your choice.
Some links to answer the eternal backup question.
New entry into the open or free WiFi mesh market.
For fulldome production. Blender is a free open source 3D graphics program, and the one I have spent the most time on.

I'm reposting this as I get closer to building it. I have the current metering chip and may tackle it soon.
Update: Jeff's example code is written in Python. I'll need to look at this, at least:
Thanks Rob! I needed this a couple of weeks ago, when I struggled with the number 1 item on the list, then discovered I needed a Windows-only utility to upgrade the firmware.
An open wiki where anyone can easily post a Google Earth window and description.
From the Xbee hive at ITP, of course.
This is two years old - I'll have to see if it has been updated:
This group sponsors high school scholars:
And here's one of their associated projects, using Google Earth and multiple sensors, webcams, and overlays.
Then there's this page of hundreds of maritime maps using Google Maps, and Google Earth:
Examples of using Sketchup in the new Google Earth browser feature.
Examples and demos of a variety of browser displays using the API (which is not really new - it's just finally available for OS X):
And the most basic example, a variation on the classic Hello World:
A screengrab from Google Earth and a link to the 3D Warehouse model:
And a webpage with embedded Google Earth player and Girls Club model (updated 12/20/2008):
Good resource for students of Processing, both enrolled and self-motivated.
We'll want sunlight controlled dimmers in the building if we want NYSERDA incentives for that energy saving addition. How would we do it off-the-shelf? How DIY?
Elaine Schele posted a small profile and tribute to Justin Kerr, with some good links and a photo of Justin with his rollout camera.
Still not sure I have a handle on the values on the y axis. I'll keep playing. Update: better now. Gnight.
Another update: adding the second graph. But ranges are screwy again.
12/18 Update: switched to new feed after mystery freeze up.
Calderon promises to seal the border with Guatemala.
So my hair is thinning the same way my Dad's did. I'm spending a lot of time tinkering with electronics. I remember how tall his workbench used to seem, the mysterious tools and smells when he worked on his radios. I never knew a lot about what he did at work - he had a security clearance, it was Cold War R&D on the fringes of '50s and '60s Washington D.C. - but I knew it had something to do with the space program. Yesterday I read in Airstream Magazine (I bought a '58 Overlander 2 years ago, to turn into a recording studio in the new Girls Club) that Melpar, my Dad's employer, had built the Airstream-based quarantine units that the astronauts had to stay in when they came back from the moon. Couldn't let alien moon-bugs destroy the Earth.
When he died in '92 he left his workshop as messy as ever. But while he was alive it had an animating intelligence. Afterwards it was mostly junk. But I claimed a circuit-board vise and kept it for the next fifteen or so years. It got lost in the shuffle, though, and I miss it. I'll have to order one just like it. I need it now.
These guys are serious. Public libraries of printed circuit board designs, and all the information to use them and design your own. Thanks Sparkfun!
The third part of the Arduino-Processing constellation. This is open source electronic design automation.
Not quite Rudy Rucker's Software-Wetware-Freeware-Realware but it is a brave new world.
In response to the Enerjar, Cornell students came up with this safer design for a power metering and computer controlled remote switch. This is very close to what I have been looking for. Nice work.
As friend Chris says, "we'll see".
Actually it is impressive to see Reforma closed to traffic and filled with bikes on Sundays.
More information (with illustrations and diagrams) of the new technology which generates energy from vortex induced vibrations around tubes mounted on the river or ocean floor. Big advantages - safer for marine life, works in low speed currents.
Hillbilly. Hell yeah.
And a free utility to make it even easier:
First test graphs. The top two show a snapshot as of this post, using two sliders on an Arduino, as I tested, slept, tested again today including a flatline when I tried a software combination that did not work.
Update: I have reassigned the input sensors, from the sliders (which I was changing myself) to the light and temperature sensors on the shield. I may need to abandon this first feed at some point and start a new one to get a useful range on these new sensors.
At the link below you can see the updated sensor graphs on the Pachube (patchbay) website.
UPDATE: I deleted this feed and created a new one, to use update software on the site. See this post.
