Digital powermeter

written by Javier on 3/03/2009

Alexandre Girard, the technical mind behind Feevy, is a what I would call a *real* hacker. He is now into building a Power Meter for household usage. That is a device that measures the amount of electricity that you spend at home, so you can have a greener usage. 

He is going to make it with two arduino boards and I presume it all will be opensource. That’s why he’s asking for donations (besides explaining the project) to raise the €145 he needs to do so. Not a big deal.

I wonder how many different things you can do if you use the capabilities of an arduino board to do such measurements: all that information in digital format asking to be designed and displayed in many ways.

Good luck, Alex!

    The “how-to display” issue is a really interesting question, as it’s still a new domain where a lot can be experimented.

    Here are some examples of what’s available today:

    - Telefonica Domotic in Madrid: http://www.flickr.com/photos/alx/2679463771/
    - Pachube feed: http://www.pachube.com/feeds/1239
    - Google Powermeter: http://www.youtube.com/watch?v=6Dx38hzRWDQ
    - Current Cost applicance, let’s see when your iPhone will do that :) http://www.currentcost.com/product-cc128.html

    As a developer, I would just “copy” these ideas, but if anybody feels like experimenting how-to output these data feeds, feel free to contact me :)
