I blogged previously about replacing one of my switches with something a little smaller, quieter, lighter and greener: https://tickett.wordpress.com/2011/12/29/a-few-small-updates/ this was all part of a pretty big rewiring of the network and relocation of the A/V equipment.

All of the devices were in a cabinet in the corner of the living room:

But now I wanted to add the new switch and relocate into the utility room adjacent:

And re-run the wires a little differently (I’d previously used existing holes to get upstairs):

I’ve already pulled most of the equipment out of the cabinet and the cables just keep on coming:

The previous excess cable "neatly" spooled behind the cabinet:

Some hours later- a little progress:

Now upstairs. You can see the grey "conduit" I ran alongside the copper pipes with the existing cables:

Here’s the new hole in the ceiling:

And in the floor to allow cables to be pulled without lifting the floor:

Now the carpet’s back down and the cupboards are back in place:

First few lengths of Cat5e pulled through for 2 connections in the master bedroom:

Back downstairs, lots of velcro to tidy things up:

The comms cab starting to take shape (still a mess but I’ve still got a lot to do):

*EDIT* This project has been abandoned in favour of a much larger project home automation hub: https://tickett.wordpress.com/2011/12/05/more-jeenodes-my-home-automation-hub/ which is now successfully logging data to pachube but still a long way to go!

I’ve been trying to find a Weather Station (only really interested in the temperature, wind speed, humidity, rainfall etc would all be bonuses but not necessities) which connects to the LAN so i can access the sensor information from my laptop/pc or office via the internet. My search didn’t come back with much:
-some reasonably priced USB devices but i don’t want to leave a computer connected to it 24/7
-some extortionatly priced network devices which look like they belong on a NASA space station

So i thought i’d take a look at what my options are on building something myself (how hard can it be?! :)

My first thought was- I need a networkable device with a web server that i can “customise” and a device which can bridge between the software and hardware. The devices i found which met these criteria:
-Router (w/ USB): Already runs a customisable o/s (sounds like DD-WRT or Open-WRT are ideal)
-USB Bit Whacker: Adds digital and analogue input/outputs to a computer via a standard USB port (and already proved to be connectable with DD/Open-WRT http://forum.sparkfun.com/viewtopic.php?p=44501 and http://forum.sparkfun.com/viewtopic.php?p=44501)

But after further research i stumbled across PIC WEB Server (http://www.coolcomponents.co.uk/catalog/product_info.php?products_id=41) which appears to be a PIC board with an ethernet (rj45) connection and built-in tcp/ip stack and web-server.

Anyway- i still have a lot of research to do before i know exactly what i need to start building my device but i’ve ordered a PICKit3, some breadboards, PIC chips and various other components to start learning!
