My site is: http://www.wattoogle.com/ I need this ASAP, please provide a time line when/if possible. ---------------------------------------------------------------------- The short: I need the same counter that this site has http://www.blackle.com/. (The counter is based on the length of time a visitor is on the main page, not a per hit basis). I also need a "money saved" counter, which will be calculated with the value from the wattage. ---------------------------------------------------------------------- The long: ->What I need: I need a "wattage counter" and a "dollars saved" counter. ->Wattage Counter: This counters must have the ability to track each and every individual user's time spent on the site in seconds. The seconds will translate into a counter that will be displayed in plain text on the site stating how much kilowatts were saved (based on 20W, which I should be able to change in the script if need be). For example, if there are users who are on the main page for 10hours, that would be 10 watt hours, which in this case will be 200Ws. Please take a look at: http://www.blackle.com/ Watt hours saved for an example. ->Savings Counter: This counter will be based on $0.10/kW·h, and the data collected above will allow this script to be written very quickly. In a nut shell I need this script to be written so that it will calculate the total cost of 20W. ->Programmer requirements: You must have a good understanding of wattage and how it's calculated, or at lease be able to learn it accurately, it's not very hard at all. If you need any reference I'd recommend reading http://en.wikipedia.org/wiki/Watt-hour. ->Programming requirements: This should be written in PHP, in a clean, documented and easy to follow format. If I need to modify any of the numbers I should be able to without any further help. There should be a referral system (so that others cannot put the script on their site, only www.wattoogle.com and localhost can). ---------------------------------------------------------------------- Thank you all for looking.
He said PHP. One thing I wonder though, you may as well pull a number out of thin air not so much unlike what blackle.com does, as they seem to base it on 15 watts is saved by every user who visits which is completely unrealistic and isn't really supported by any testing (I have however read figures of a more conservative 7 watts decrease in power usage for a 17" CRT). That's only on a CRT monitor anyway, which makes up a small proportion of the monitor market now.
You're probably right, but the point is to get some savings, and we're all happy. Check out the chart at: http://www.microtech.doe.gov/EnergyStar/info.htm#display
