Enermax's (horribly named) Liqmax 240mm unit goes for €71, and from a very quick google performs with the best of 'em as well.

Now that is an interesting lead

I know its not the best place to ask but I'd only be wasting time opening a thread over in broadband / nets & comms, has anyone here experience with ubiquiti gear for doing a point to point link for internet?

The house just seems like it'll be years before there's a better connection available, so I was considering the option of getting fibre to my parents business premises and a link from that back to the house. I'm not planning on becoming a wisp (:D), ideally it would be replacing adsl broadband subscriptions, line rental and phone at both locations, with just the one fibre connection and associated costs of the link. and doing ip phones and have both numbers available at each place (which was the original idea)



distance 3.9kms. Looks to be flat enough all the way and not much in the way.

Should I bother going any further with the idea? Or does it look like it could be worth it. If it seems like there's a good chance it would work then I'll probably do a proper thread for it to decide what kind of equipment to use and such

ED E

Google maps is no good for LOS but if its actually there then you could have a runner.

Step 1. Grab OSI maps and check the elevation at both points and between

If you're only just clearing the motorway then its a no, you need to be higher than an artic.

I have used a good few nanostation M5's lately, mainly point to point and point to multi point for CCTV links. I have links at 300Mbps at 95%+ Transmit CCQ at 6Km with line of site without any issues, though obstructions like trees can cost you up to -20db. M5’s are good for 25Km theoretically.

Line of sight is important, especially with 5Ghz, I have not used them but apparently 2.4ghz and even more so 900Mhz work a lot better on non-line of sight/obstructed links. Any way you can hop up on the roof with a ladder and have a look? Good tip is to stick a flag (try the Limerick one ) on one roof, and get a pair of binoculars and have a look. Ubiquiti radios have loads of useful tools for alignment and a spectrum analyser to find a channel with minimal noise & interference, so setup is easy enough. They have decent support forums, and I got good tech support from the wholesaler I bought from at the start.

Let me know if you need any other help.

ED E

Looks like its semi built up so using 2.4Ghz may not be great, plenty of noise sources.

Can you use 900Mhz here? Its largely licensed for LTE use.

glynf

Good point, if its used by mobile phone comms not likely. GSM signal boosters can only be sold to licensed installers IIRC.

frozenfrozen

Thanks lads,

Just checked an os map, the house is showing as around 20m, the land in between dips down to 10m (including where the road is) and the destination then is 10m, but just from knowing the area it does appear slope up on the street the business is on, so there's easily another 2-3 metres of elevation, then the height of the building itself

when its dry I'm going to measure the height of the house and have a look from the ladder to see if I can see the other end, there's a lot of trees surrounding the building on the other end but they would be no higher than the roof so I hope I can spot that, and I'll try do the same in reverse over the weekend and get a good idea of the lay of the land.

No flegs involved yet There's a big landmark a few hundred metres from the end point and I know for definite you can see that from the roof here, so that'll make it easier to get my bearings for finding the place with binoculars.

I was looking at 5GHz mostly for the throughput but I wouldn't be against 2.4GHz or 900Hz, 900 could give me to make it worthwhile, the calculator is saying 42mbps tx at 10MHz / 84mbps at 20MHz.

so if the trees are an issue that could be the answer. Although that would probably more come into it for hills and other obstacles?

I'll be back for more info anyway definitely

ED E

Toshiba SSD, known dodgy (Apple recalled them). Controller died around chrimbo.


Just baked it in the oven (paupers reflow), now we've got a raw disk to work with

frozenfrozen

if its raw you need to put it back in the oven, I prefer my ssds medium rare

What are peoples thoughts on a 'hardware swap' thread? We have such a tightly knit community here I would only see it as an advantage but just curious on others opinions

Xenoronin

Sounds interesting. Not sure how viable it is with such a small community, but definitely interesting. What kind of hardware would people usually swap?

Serephucus

Wouldn't it end up being something similar to the gear selling thread?

I'd like something like this - something that would let us sell/trade internally - it would be very small sure, but probably a billion times easier than dealing with Adverts, and a handy first-stop for people thinking of putting something new together. I just dunno how viable it would be given Boards' rules, etc.

Or are we talking purely swaps? Because I see that being even smaller again, unless I'm missing something.

So grape vines be a talking. Zen single thread performance not that far behind 6700k

Looking for a benchmark to use that I can keep the same version of for a while. Cinebench R15 is standalone and is nice and consistent where as the likes of PCMark get updated so running it 18mo down the line I have less faith in a fair test. Mainly CPU/productivity. Suggestions?

frozenfrozen

Cinebench is my favourite anyway. Small filesize, quick tests, and easy / sensible numbers for comparing stuff.

Got approved to RMA a faulty PSU back to EVGA but the issue is postage. The PSU only cost about 30 quid at the time and looking at shipping its a similar price to ship it back. Am i better to forget about it or do you guys know of a cheap way to ship to the UK?

Parcel motel might be worth a shot.

If it's just a basic €35 430w psu or whatever, easier to just buy another from Amazon or the like - brand new unit, new warranty, and so on. No matter what, it'll cost you a fair chunk to ship it back to them. That's the problem even with cheap PSU's that have a 5 year warranty - once your retailer warranty runs out, it costs almost the value of the PSU again to send it back. Most people probably don't bother once the actual retailer warranty expires.

Its just an Evga 500B. Unfortunately bought from Hardware Versand before they went bust. I might just look into Parcel Motel, looks like about €15 to return. At least ill have a refurb PSU then that i can throw into a spare system. Will be cheaper than buying another 40 ish PSU off amazon

Kinda cool

Yeah it's pretty slick, the numbers are mind boggling, I wonder how they compute the performance if the emulated GPUs run slower. 16Billion transistors is mental. But in comparison a 16 GB flash drive contains roughly 64 billion transistors. The Human brain has at least 100 trillion connections.

Can anyone recommend me a set of headphones for work? Since they're for work they need to be:

• Not very expensive
• Noise cancelling / Noise insulating
• Subtle - My headset at home is too big

Had a poke around Amazon but I figured it would be better to ask around..

I was recommend HyperX Clouds myself and VERY happy with them.

Cloud 1's or 2's. Went for the 2 myself. Great headsets.

More expensive than I was looking for!

Although.. I guess I could buy those for home and being my Sibera V2 to work

They're well worth it. Best headset for under £150

Honestly I'd use IEMs in work. If you have hair, no headphone hair. Don't look like a gamer. Even cheaper units have great isolation. Don't look like you're gaming/faffing off.

Second this. I usually use IEMs. Most of the lads use headphones, as they can be more comfortable for longer periods, but I prefer the bang-for-buck quality that IEMs tend to have over full-size cans.

Anyone know a quick and easy way to calculate roughly how much energy your gaming PC uses on a 2 month bill? Never bothered to check it before but I'm just curious now after reading a thread about power usage but the prices were for American users.

Serephucus

ESB has a calculator yoke somewhere. Stick in "standby" and "on" power (I use those for "idle" and "gaming"), and hours on per week (hours gaming, in this case) and it'll give you a per bill price.
