My network at home up until recently has centred entirely around a cheap ADSL router from O2. This is fine, but I decided to move the DHCP duty over to my little home server. As part of this, I thought it would be nice for it to also handle DNS, and dynamically assign DNS names to the machines it learns about through DHCP requests.

The first three parts of this series talk about the hardware and software I have set up in order to capture my energy usage. Of course, it's a good fun (and somewhat geeky) project but ultimately the aim is to help me save energy. So now it's been up and running a little while, it has yielded results which have taken a slightly unexpected turn.
