My Node0 built in a double
wardrobe cupboard. Gets quite hot in there with all the kit
though. I did add a ceiling extract fan (an in-line bathroom
type) that is controlled by an X10 AD10. This means I can turn
it on/off as necessary. I currently have it turning on at 08:30
and off when the Comfort alarm is armed to night mode (as the
fan is a little noisy). The next upgrade is to fit a quieter fan
with a bigger air flow as Node0 still gets very warm in the
It started off with a small
cupboard, but after the garage has been partitioned into two
spaces I ditched that and bolted everything to the desk/wall ;)
It also answers one of the questions asked a while back about
running stuff from the garage. Mine has been operational for a
number of years and as long as you keep the gear running,
condensation or cold (is actually a bonus!) is not an issue.
Only thing to do is when you do switch off (and leave off for a
while) stuff is to bring them indoors and let them become room
temperature again before you start them (as condensation will
have settled then).
My Node zero is spread out across
two walls in the garage, so no single photo could do it justice.
This photo shows the CBus wizardry.
The top two cabinets contain a single eight channel dimmer and
three twelve way relays.
The lower cabinet is a recent
addition and, following a suggestion from a fellow UKHA regular,
contains contactors to further protect the CBus channels that
drive the outside security lights. In addition to CBus, I also
have a Comfort installation.
Further details and more pictures
are on my web site, with more being added all the time.
This is my first attempt at a
Node 0. I'm currently building a house in N. Kent so I have been
able to integrate it in the basic design. Having been a Manager
in several Telecoms companies I have seen quite a few Data
Centres and have copied most of the ideas from these.
Flexibility is very important to me so I have several patch
panels and have also used cable routes that can be easily
accessed. The other design requirement is that the rest of the
house should look as 'normal' as possible, so my Node 0 is the
only place for me to express myself. Any questions or comments
e-mail me at firstname.lastname@example.org
Node 0 is a custom built
cupboard(s)/desk in my office. Other than LCD screens, ceiling
mount speakers and Xantech IR eyes we have NO equipment anywhere
else in the house that's visible.
The whole idea was that with the doors shut it looked like any
other cupboard and was pretty much silent, its built from ½ inch
ply and mdf and has been sprayed to match the wall colour in the
office, due to the weight of the equipment in the racks the
structure is tied to the ceiling and floor joists.
To the left and right of the desk we have two full height rack
enclosures containing all PC and AV equipment and above the desk
contains the wiring patch panels for data, voice, audio and
video. Below the desk are the C-Bus consumer units for the
lighting. The right hand unit also houses the Comfort alarm
install although this is not visible from any of the pictures.
Calling it Node 0 is probably a
bit grandiose but it is where most of my bits sit under the
The space is just 44x44x54cm
hence why it looks so cramped. On the left are the incoming
BT lines (3), patch panel below and HomeVision below that.
Back wall houses the 3x8 pabx with two switches in front
sitting on the Vigor 2600+. Finally on the left we have
power, wireless AP and an MSS100 for Homevision. The main
servers are in the garage and Sky is distributed from the
In node 0 we have termination for
the 3 CAT5 sockets and coax from each room, and the usual
router, switch, cable modem. The bottom right houses a 1-wire
hub currently monitoring six room temperatures and providing
switching for the heating. The box on the right that looks like
a doorbell actually is an wireless doorbell receiver hooked into
the 1-wire network. The rest of node 0 stores all those old PC
bits and pieces I'll never need but just can't throw away (like
an ISA SCSI card).
Node 0 is in the upper half of a
closable, custom built cupboard in MDF on the first floor. It is
fully functional in our newly build home since 2 years. On the
left hand side are the incoming (mostly CAT 5) cables from our
home (IR-sensors, phone connection, TW 523, Camera's and other
Video connections, security connections and control, smoke
detection, anemometer, temperatures, etc.).
They interconnect in a flexible
manner to the Node 0 equipment side: the Homevision controller,
a laptop PC linked with the WiFi + ADSL home network, a Power
distribution board + supply unit + battery, + an I/O board (with
relays and allowable windforce detection: 5 Bft), an X10
integrity testmodule, a phone unit and TW523. On top of the
controller is an IR + RF relay unit for remote control of the
variuous automated functions in the house or vicinity. The
laptop is used for the Homevision monitoring software, the
always on line Internet weather information data exchange and
also as a simple PC-scope for measurements via the PC soundcard.
This is my Node Zero, and it's located in the
loft. I have a number of devices located in a 19'' rack. From
top to bottom, the order is as follows: Power strip (6 sockets)
o Linksys 18 Port 10/100 Switch o 48 Way CAT5
Patch Panel o Netgear ADSL Router o Mini Keyboard & Mouse o
2xUHF Modulators (CCTV Camera 1 & 2) o Home Security Server (CCTV)
In the rack is a room thermostat that is
connected to two high speed (but noisy) case fans in the Home
Security Server. When it gets a hot up there, the fans kick in
and create a high through flow of air through the case, and stop
the server from overheating. Overall, it has been worth the
effort, and keeps everything much tidier and less prone to
'accidents' when in the loft!
