Keeping an eye on your server health isn't the most romantic of pastimes. That's what compelled modder mkanoap to build a computer-free monitoring system that was as cheerily simple as Xymon's red ...

If you want to DIY solution to your energy consumption, here's how modders created a home energy monitor from an Arduino, some wiring, and a little custom code.

This hack takes advantage of all of these aspects to bring you an Arduino controlled CGA monitor. One problem with experimenting with one of these monitors is that they are not that well documented.

Still, it's a handy project if you need to monitor and track the air quality in your home. Hit up the link below for the Arduino source code, a build guide, and all the details of the tests.
