Home UPS

Looking at a few UPS sites, http://icrontic.com/articles/super_ups, has set me up with enough info to put my house on batteries. still a few questions I have. can you get deep cycle gel cell batteries? I ask this as I heard lead acid batteries let off a gas that can corrode metals, rust silver, and if not well ventilated can cause a serious fire/explosion risk. If any one can give me a little more info on this it will be great.

secondly, I am looking at attatching my UPS to my distrabution board. supply from main trip to UPS and UPS to trips for lighting and plugs that supply power to the office, and tv and DSTV. kettle too, possibly microwave. maybe jacuzzi, but thats going a little far. Ok the Kettle will have to have its own battery. a car battery to be specific. Watch for part 2 for the explanation.


Any opinions, please! Im not too keen on blowing myself just yet. batteries are pretty scary things to work with

Ubuntu Networking

I have been playing around with my wireless and mucking about with my mac address. these are just a few useful tools I have been using.

I picked these up off the net somewhere, when i find it again I will put the link up. there are many web sites on macchanger.

sudo /etc/init.d/networking start
sudo /etc/init.d/networking stop


sudo ip (Untitled 18) set wlan0 down
sudo macchanger wlan0
sudo ip (Untitled 18) set wlan0 up


machanger package will need to be installed, I normally search for programs in synaptic package manager, and download them from there, unless the link is shown on the page.
