Tweet-a-Watt

This project documents my adventures in learning how to wire up my home for wireless power monitoring. I live in a rented apartment so I don’t have hacking-access to a meter or breaker panel. Since I’m still very interested in measuring my power usage on a long term basis, I will build wireless outlet reporters. Building your own power monitor isn’t too tough and can save money but I’m not a fan of sticking my fingers into 120V power. Instead, I’ll build on the existing Kill-a-watt power monitor, which works great and is available at my local hardware store.

this looks like a fun project

Earth Nervous System

He aims to develop a panoply of microscopic-scale nanotech devices that will be able to measure essentially anything – and at low cost to boot. Viruses, bacteria, the chemical composition of molecules, vibration, moisture levels, particular sounds – these are just some of the things that the super-cheap devices he envisions will be able to detect. “A very tiny laser would light up and we could look at the optical spectra of chemicals. Each one is like a fingerprint, with a unique spectral identity. That would be a single universal detector.” Though a laser capable of such a task would today cost around $100, they can eventually be produced for about 10 cents.

the planet-scale sensorweb is coming. baby steps towards the angelnet. An angelnet is any all-pervasive distributed processing supervision and safety infrastructure.

Radiohead House of Cards

LIDAR enters the mainstream

Radiohead just released a new video for its song “House of Cards” from the album “In Rainbows”. No cameras or lights were used. Instead 2 technologies were used to capture 3D images: Geometric Informatics and Velodyne LIDAR. Geometric Informatics scanning systems produce structured light to capture 3D images at close proximity, while a Velodyne Lidar system that uses multiple lasers is used to capture large environments such as landscapes. In this video, 64 lasers rotating and shooting in a 360 degree radius 900 times per minute produced all the exterior scenes.

BrightEarth

BrightEarth is a project dedicated to exploring ways in which a new generation of Internet mapping tools can improve the sharing of information about humanitarian issues, both among the organizations directly involved and with the wider public. BrightEarth will help humanitarian organizations publish information to 3D virtual globes such as Google Earth, ESRI ArcGIS Explorer and NASA’s World Wind.

Open Aerial Map

Open Aerial Map is a non-profit, open access, meeting place for the aerial imaging community. It exists to provide a freely available image map of the world created solely by community contribution, and to facilitate the free exchange of imagery, technology, and ideas. In order to provide an unrestricted, free, an unbiased view of the world, OpenAerialMap encourages the free exchange of aerial imagery, without restriction on its use.

that & gps data & lots of people = free maps for the world.
