Working on cabling layout now. When running 240VAC and Cat6 data cabling down from ceiling void to a shared wall socket, I'm assuming putting both in same channel is not best practice. So my question is: what is a sensible separation between parallel runs of mains and data cables? 2cm, 5cm, 10cm? Closer in blockwork than behind plaster board? Or am I being too picky about this?! -
Ok, don't shout. Cat 6 cable already installed going to a kitchen island. It feeds 1xcat5 data point. Would it be, setting aside perfection for a moment, possible to use the non data pairs of a cat6 data cable to power 2 short pieces of RGB LED strips? How many of the 4 pairs are actually servicing the data point? If it's 2 pairs, then are the other 2 pairs redundant? 1 pair leaving 3 redundant? This is with a view to cutting, splicing and hijacking the cat 6 under the island, and doing the same 1.8m away at the plinth where it reemerges, but still retaining the use of data and the cat5 outlet as normal. Its low voltage so no legal infringements as far as i can see? Ill get my tin hat polished. TIA -
Please can anyone give guidance on the cost of installing a data network? I had asked to be installed twin data sockets in LR and 3BRs, and my contractor has put in an additional cost for the labour that seems to me to be exorbitant. The plans were not specific on this matter, and the sparkie had given an overall cost that did not break down items. The cable is inexpensive and I had provided the hardware. I had had put in the cables as a contingency, particularly since it had been suggested to me that e-transmissions through insulated walls are poor, so I wanted to be able to wire phones and the like if necessary; tho actually the wifi seems to transmit ok.

I've got my virgin wifi / router / hub thing in my 1st reception ( dining ) room downstairs. Now I need to get cat5's throughout the house and not enough outlets on the virgin do-dah. 1) Will the wifi be better with do-dah moved to mid house first floor, at floor level? 2) Can I take 1 cat5 out of do-dah and go to a larger ( more ports ) mains powered router at aforementioned location? 3) Should every cat5 device have its own run from point to point? Do I run one cable to the Xbox and another separate run to the smart tv above it, or can I split the cable behind the Xbox? Multiple rooms to do with same scenario. Mucho gratsi-arse. ?

As way of an experiment I've resurrected the old Raspberry Pi to see what sort of monitoring I can put in place with low cost components such as DHT11 and DS18B20 sensors. An hour or two of dodgy scripting on my part (god my python and bash is rusty..) and I've got a nice neat cron script that is logging data every 2 minutes pretty reliably. As I'm inherently lazy when it comes to backups and other stuff, I decided to use one of the online services for IoT to log to. Logic is that if I log at short enough intervals then any lost data points would be averaged out. I can also download the data if needed so it's not like I can't review the data offline Has anyone else done anything similar ..??

CIC online offers a really well collated set of information But, I get the feeling that, since it's a project funded by several Higher Education Institutes, the project is likely to be pruned. The site isn't as useful as it might be because there's no site-based search facility. For example, I'd like to have researched 'Thermal Mass'. Purely for reference and research purposes you understand. However this page was the most useful starting point for me : it lists a set of relevant categories It's best to register (they'll ask you to do that for some resources -not all) -
I needed to do a bit of research about my local area and bumped into this site. My motivation was to research the relationship between GCN (Great Crested Newt) distribution and temperature. The reason the site is useful is because it refers to other data sets, and either draws on them for 'its' own use or hyperlinks to other useful sets (like this one)
