Earth Browser is another Pachube.app quickly knocked up in javascript to make it easier to search for Pachube feeds, displaying the realtime values of the search results distributed across the planet. Using the app, you can overlay new search results by changing bar colours and supplying new search terms. It's available at http://apps.pachube.com/earth_browser/ and this video shows how you might use it.

As we've said many times before the reason we launched Pachube was to take care of the messy, difficult things (like storing floods of data, serving and sharing that data, creating embeddable graphs, authenticating access to the data) so that you, the community can build useful applications on top of it.

One of the simplest ways to build web-based applications that use this data is to work in Javascript.

A good example of such an app is Feed Finder, a little app I knocked up this afternoon to show how, with the new search API parameters, you can quickly build a powerful 'browser' to discover useful and interesting Pachube feeds. It's available at http://apps.pachube.com/feed_finder/ and the video documentation below shows how you might use it.

Below are a couple of sketches for Arduino Ethernet: the first can be used to share sensor data with Pachube and grab remote sensor data, so you can effectively have both "local" and "remote" sensors; and the second enables you to control Arduino Ethernet via a web page.

These sketches should make Arduino-based web-controlled home automation, and remote-responsive spaces a lot easier. The advantage of working with an ethernet shield is that you no longer need to tether the Arduino to a computer in order to access Pachube and other network services!
