Pachube (pronounced "patch bay") is a web service available at http://www.pachube.com that enables people to tag and share real time sensor data from objects, devices and spaces around the world.

The key aim is to facilitate interaction between remote environments, both physical and virtual. Apart from enabling direct connections between any two environments, it can also be used to facilitate many-to-many connections: just like a physical "patch bay" (or telephone switchboard) Pachube enables any participating project to "plug-in" to any other participating project in real time so that, for example, buildings, interactive installations or blogs can "talk" and "respond" to each other.

Here is how you can add your iphone's geolocation as a Pachube feed. (Warning this means you will be trackable at all times.... use at your own risk!).

1. you need a hacked/jailbroken iphone. Try this: http://www.modmyifone.com/wiki/index.php/ILibertyX
   You will also need a php host.
2. install Erica Sadun's "findme" application. her installation tutorial is here: http://www.tuaw.com/2008/02/21/tuaw-responds-iphone-lojack/ (and this tutorial is based somewhat on that procedure). as it happens i used the application here: http://ericasadun.com/ftp/TUAW/findme/
   rather than using "findme" i decided to use

Lots of new features for Pachube users! You may have noticed these already -- they include:

• profile pages: can be found at: http://www.pachube.com/users/YourLogin
  For example, for the Haque Design + Research office, the profile page is http://www.pachube.com/users/hdr. Here you can fill in information about yourself and, under "settings", select which bits of information you want to make public.
• stats: you can view your stats (and make them public in "settings") which tell you how many times you have accessed feeds daily, or in total and how many feeds you have published.

Usman will be leading a 2-day workshop, June 21 & 22, at Arup's headquarters in London, with a particular focus on using Arduino and Processing with Pachube. The Extended Environments workshop will form a basic introduction to networked sensors, making particular use of Extended Environments Markup Language (EEML) and Pachube. Please join us if you would like to go learn more about using Arduino to connect together remote environments across a network, share sensor data, or create interactive environments using Pachube.

we'll figure out a way to do this straight out of the pachube site some time later, but in the meantime, this is a bit of a quick hack: how to connect a pachube feed to twitter so that you automatically twitter with your latest pachube data.

first you'll need somewhere to host a php file, and set up cron to run the command at regular intervals.

your php can look something like this (i'm sure there are more efficient ways to do it):

http://pachube-jp.blogspot.com/ has some tutorials about Pachube, including a translation of the Arduino step-by-step tutorial and an introduction to using Flash with Pachube.

This document explains how to use the various features found on Pachube.

Browsing for feeds

You can use the map to find feeds of interest. Markers indicate a feed that has been added to Pachube that is located at that particular point on the planet. If you are a registered user then you can also use the real time sensor data from these feeds.

Using "List" view and searching for particular sensors

If you know what sensor data you are interested in connecting to you can either search for it or select something in the tag cloud at the bottom of every page.

"List" view is a quick way to view all the feeds.

To connect to Pachube using an Arduino with ethernet shield serving EEML sensor data, try one of the following (at the moment these are examples for providing inputs to Pachube -- i.e. to share your sensor data -- not to use outputs from Pachube -- i.e. other people's sensors):

1. Arduino with Nuelectronics.com Ethernet Shield: download this EEML server template for Arduino
2. Arduino with Lady Ada's Ethernet shield: download this EEML server template for Arduino EEML server template for Arduino. This forum post may also help.

Further information will appear here as the shields are tested further.

Pachuino is an Arduino with both local and remote sensors. It makes use of Pachube to provide real time remote sensor data (and to share your own local sensor data); and an Arduino loaded with Firmata, tethered to a computer connected to the internet.

Here you will learn to build your own Pachube/Arduino/Processing application step-by-step, connecting Arduino to Processing to Pachube. This tutorial consists of two basic steps.

1. Use Arduino to create an input to Pachube (i.e. provide Arduino's realtime sensor readings for others to connect to).
2. Use an output from Pachube to control Arduino (i.e. to have your Arduino respond to realtime sensor readings from remote devices).

If you are comfortable with coding then you can use the guidelines below to get going. If you want a nudge in the right direction and you intend to use Arduino/Processing (or a similar setup) have a look at the tutorial on using Arduino for Pachube.

1. To use Pachube, you can signup here: http://www.pachube.com/signup -- at the moment you need to request an invitation code from beta [ at ] pachube [ dot ] com (and include a couple of lines about what you would like to do with Pachube). Please note that registering for Pachube, the service, is different from registering here to write in the community/forum/tutorials/comments, etc.
2. You will receive an email detailing your Pachube account login and password details. These are used for accessing the Pachube website.
3. In a separate email, you will also be issued with an API key. You will need this in your code to authenticate your application's access the Pachube service. Don't share this with anyone: it's just like any other password.
4. Determine whether you will be making inputs to or using outputs from Pachube (or both). If you have a microcontroller and sensors and you want to make real time data available to others, this would be considered an input to Pachube. If you want to make visualisations from other people's real time data or have remote sensor data trigger things in your microcontroller this would be considered an output from Pachube.
