It's an open source power monitoring kit that mods an off-the-shelf power meter which can 'tweet' (publish wirelessly) the daily KWH consumed & Cumulative Kilowatt-hours to your Twitter account, Google App Engine, Facebook, IRC, whatever ... They recently won the 'GreenerGadget' design competition and have now released an open source hardware kit."

Open Source Russian Vacuum Fluorescent Tube Clock 155 comments
ptorrone writes "Hacker extraordinaire Ladyada (whose open source hardware projects we have discussed before) has just published a complete how-to, with design document, on making your own open source Russian vacuum fluorescent clock. The vacuum fluorescent tubes aren't as dangerous as (high-voltage) Nixie tubes, and there seem to be more of them available in the world. If you're not interested in building a clock from scratch, you can also pick up a kit version. All the schematics, source code, and files are available on the project's page."

Isn't that missing the point? (Score:2)
Installing a lot of hardware that uses power to monitor it, connect to the internet, and send the email? Wouldn't it be far less overall pollution to just read the meter by hand? I can see this as maybe useful for corporate offices, but then you wouldn't want a tweet, an email, web service call, or database write would make more sense.

Another point is in order to read the power meter you generally need to wander outside in some hidden corner of your house, or down into a hidden location in the basement. It's really hard to keep that routine up. Adding the hardware may take just a touch more power, but at least that data is in a

I don't know about you, but my computer is nowhere near my power meter. Not to mention the handy monthly usage monitoring that comes courtesy of the the power company. Its cool in a geek sense that making anything is cool, but its rather useless overall, and if you really cared enough about being green for more than the appearance, you'd find the time to check the actual meter rather than wasting your power (oh, and you'd be turning off your computer when not in use, which would save far more power than m

Aggregate power consumption would be nice... (Score:1)

Why would I want to monitor usage on a single plug? ... Having a view in the aggregate would encourage people to disconnect devices using power in stand-by mode, etc
I almost completely disagree... with only aggregate information, you don't know what to turn off. You can't point and say "hey, the TV is using quite a lot of power in standby", because you don't know what proportion of the whole is due to it. Even if you compare the aggregates across a couple days, one with the TV plugged in and one with it not

Yea, there's a meter on the side of your house that does this for you. You don't really want something that bugs you every time a fan turns on do you?
Too much work? Your power company sends you a nice note each month telling you what your consumption was.
That's what I did anyway. I found that my "stand by" power usage is so small it got lost in the noise.

I actually agree with you. My wife would kill me if I tried to string up extension cables across every room just so I can tweet my power usage. Not to mention, I don't know if a single plug could handle all the stuff in my television/computer room. Besides, how many houses do you know that plugs every electrical device into a socket or even 110? What about the Fridge and the dryer?
Give me a way to measure my whole house, then graph it over time, then I can do something with this.

What's the difference between a single plug and a string of plugs off the same circuit?
Most household circuits are running off 20A breakers anyway. Your whole office is probably off the same circuit. Normal plugs can handle 15A an the plugs with a horizontal cut in them by the one plug can handled 20A.
But you can plug devices in and read how much power they are using. Keep plugging until you get close to 1500 Watts.
You really want to graph your whole house by outlet. Then you can "optimize" from the dat

I'm using The Energy Detective (http://www.theenergydetective.com/index.html) and a custom version of this python script (http://svn.navi.cx/misc/trunk/python/ted.py) to measure, track, and graph whole house power consumption.

There's a company in my office building (http://www.rpi.edu/dept/incubator/homepage/ethermetrics.html) that's doing something similar, except they have a device much smaller, that plugs into your power meter and gives the reading for the whole house.
It uses little to no power but requires an ethernet cable to get online. It's got a built in web server and you can log in to check your power usage. They don't have much of a website yet though they've got a working prototype and I'd definitely get one for my o
