You should only attempt this project if you are comfortable and competant working with high voltage electricity, electronics and computers. Once the project is complete it is enclosed and there are no exposed high voltages. However, you must only work on the project when its not plugged in and never ever attempt to test, measure, open, or probe the circuitboards while they are attached to a wall socket. If something isnt working: stop, remove it from the wall power, then open it up and examine. Yes it takes a few more minutes but its a lot safer!

OK, if you agree we can move on!
To make the tweet-a-watt setup, we will have to go through a few steps
- Prepare by making sure we have everything we need and know the skills necessary to build the project
- Build the receiver setup by soldering up one of the adapter kits
- Configure the XBee wireless modems
- Build the transmitter setup by modifying a Kill-a-Watt to transmit via the XBee
- Run the software, which will retreive data and save it to a file, upload it to a database and/or twitter
- Expand and extend your setup
