home of office with the Current Cost meter
Dothegreenthing.com

What You Need
• Current Cost Meter (http://www.currentcost.com)
• Mac or Linux PC*
*NB. Mac and Linux have different instructions
Dothegreenthing.com

Linux
• Before we start you will need to install James Smith's
(http://www.floppy.org.uk) rb232 Ruby gem
(http://github.com/Floppy/rb232/tree/master)
• Then put your Current Cost meter together
Dothegreenthing.com

Step Two
• Plug everything in an attach the clamps around
a cable
Dothegreenthing.com

Step Three
• Download James' daemon from here:
http://github.com/Floppy/currentcost-daemon/tree/master
Dothegreenthing.com

Step Four
• Run the program and watch your Tweets stream in
Dothegreenthing.com

Mac OS X
• We couldn't get James' rb232 code to work, so
we're going to go a different route...
• First install PL2302 drivers for your mac

Step Two
• Same as with Linux, plug everything in and attach
the clamps
Dothegreenthing.com

Step Three - Oops, A Problem
• Unfortunately, we couldn't get James' rb 232 code
to work on OSX, but we found another way...
• The plan is to:
– Have the data sent off to Pachube (using a
Pachube app)
– Have a script that will pull the data off Pachube
and then post this on Twitter
Dothegreenthing.com

Step Four
– Sign up to Pachube (http://www.pachube.com)
– Create a Feed
Dothegreenthing.com

Step Five
• Download this app

• Download and run this code
