Buying refurbished kit is a great option. That's what we've been doing over the last year.

Splitting Digital Telephones via Switches (5 to 1)
Chris_Cook replied to Steve21's topic in Wired Networks
If its a proprietary digital system that only uses 1 pair per phone, you could use one of these at each end of a cat 5 cable: UNBRANDED - ADQ88 - Cat5e 4 Way Ethernet Cable Splitter, RJ45 Male to 4x RJ11 Female | CPC UK That's assuming you have cat5 for your phone port in the office - it would get you 4 phones. If you have more than 1 PC in the room, could you use a small switch for the PCs and free up a cat5 run? Otherwise, you're probably going to have to run more cable to the room. -
Any motorbike riders here? First time rider advice.

You won't go to far wrong with anything Honda, provided its been well maintained. CBF 125s can be had relatively cheaply, and as above, the CG125 is good. If your buying used, then this video has some good tips: Personally, I would find your nearest Honda dealer, but any of the Japanese bikes are good these days. If your tempted by the Chinese ones, then look up the bbc watchdog video. They have been known to fall apart when in use, and they will have very little re-sale value. Its also worth looking at the general maintenance of any bike you go to look at. Check for leaks, especially in the front forks and rear suspension, tire condition, drive chain, and engine oil and whether its due a service. If its not been serviced and looked after, it can be expensive and time consuming to get it sorted, as there will be more problems that you will find once you've brought it. Its not a reason not to buy, but certainly something to factor into the whole running costs of the bike. 125's are often neglected because they are run by new riders who don't know better. Labour rates in the garage can be pricey. Doing your own servicing can bring the prices down quite a bit, but takes lots of time and can be messy. YT has lots of videos on this, and its worth looking at to give you an idea of what to look for when buying. -
I feel your pain. However, it should be possible to do most things on that list, apart from sims/discover - you would need some sort of remote desktop solution or boot camp for that. It should be possible to connect to your AD. which would give you logins. You won't get GPOs, but for a one off computer that's probably not a big deal. There is an option in finder to connect to windows shares. Under the GO menu there should be a connect option. Type in SMB://Server_name/share_name. If you have a network printer, that should also connect directly, but it might bypass any print monitoring. Your printer manufacturer should have instructions. USB printers should be fine. You can get versions of Office etc for Mac. I would avoid the mac specific programs like keynote and pages, unless they can remember to convert the files every time they save. They are a pain if sharing documents with PC users.

The quickest way is probably to un-thread the cable and fit a completely new bracket : SAHARA - 1150014 - PROJECTOR MOUNT, 1M CEILING KIT | CPC UK I think that one has been over-tightened looking at the amount of thread that sticks out the back. If its damaged the thread then I don't think your going to get that out. You could also try good old wd-40, or possibly a blow-lamp and get both ends of the bolt glowing red-hot. If you let the bolt cool as slowly as possible then it should soften the metal. Another option could be to find an allen key or torx bit that is slightly too big and hammer it in. But I think the head of that bolt will just get more chewed up. It'll also damage the tool which will mean the next bolt will get chewed up as well. If you go for the drill option, then drill out the back of the bolt rather than the head - otherwise you wont be able to grip onto it to undo the remains of the bolt. You need to use a center punch to stop the drill bit slipping sideways. The black collar would then need replacing as there wouldn't be any thread left to hold the new bolt. Its probably the threaded end of the bolt that is stopping this coming out, not the head. And when you do the new bolts - hand tight only. You don't need to lean on them that much. Do them up till they stop turning easily, then about an 1/8 of a turn more at most. Any more than that, and they are more likely to fail, or be impossible to get out. Youtube has various videos for stuck bolts.

According to this, the pin spacing is 2.5mm,and no gaps between pins. http://www.dinkle.com/upfiles/proter21358919438.pdf This looks almost identical: FK-MC 0,5/8-ST-2,5 - PHOENIX CONTACT - Pluggable Terminal Block, 8 Ways, 160 V, 4 A, 2.5 mm, 26 AWG, 20 AWG | Farnell element14

We brought about 40-50 laptops so far - we are very happy, as are our students. Like others, we've had a couple of minor issues, but all sorted quickly. And to be honest - we've had less issues than with the last 2 lots of new desktops and laptops we brought. With money as tight as it is, and the number of PCs I'm trying to keep going - I would need a really good reason to get anything else.

It looks similar to a Phoenix connector. possibly one of these would fit. Pluggable Terminal Blocks | Farnell element14 There is some difference on pin spacing, but otherwise I think they are almost a standard.

Switches, differences between manufactures and pricing
Chris_Cook replied to caffrey's topic in Hardware
It depends on what features you use. Netgear are great if you want just a basic switch. But once you start doing things like VLANs etc, they can be a pain in the bum. Especially if you have several different models/firmwares. The HP stuff is still pretty low cost compared to what you could spend on switches. -
How about a refurbished HP 4250 from ict-direct?

[wanted] Viglen Genie Ultra Small Stands (All in one mounts)
Chris_Cook replied to Markallanach's topic in Classified Adverts
I have some in my store cupboard. Where abouts are you located? -
I've not used it or done an msi, but NSIS installers offen support a /S switch. Can you script it if you are just trying to deploy it? Chris

You might want to look at the order of your CV. It doesn't necessarily have to have paid experience first. When an employer looks through CVs, they want to get an idea of the candidates experience and skills quickly. So you want something in the first half of the first page about your IT skills. You could maybe start with a short paragraph about where you are and where you want to go with IT as a career. They will also want to see the skills and technologies they have asked for in the job description. Make sure keywords from the job description are in your CV and customize it a little bit for each job. Your CV might have to get past someone who isn't an IT specialist and doesn't understand how some skills transfer over for other jobs. Make sure you sell yourself as well. If there are other skills you've gained from other jobs, explain how they might be helpful - customer service and organisational skills are really useful for a technician to have. Being able to deal with difficult people or boring jobs is also valuable. It might also be worth talking to the job center. They used to offer CV and other job hunting advice. I don't know if they still do. I found it helpful. Last but not least, be prepared to send of 100's of CVs and applications or maybe even more.

CCTV Storage 30TB - Your thoughts and suggestions please :-)
Chris_Cook replied to lmgtfy's topic in Physical Security
We use milestone, and automatically archive footage after a day. We have about 200Gb storage for live data, when it runs out, it goes onto a nas box automatically. We keep footage for 21 days, and make sure everyone knows if you want a copy of the footage you need to let us know within a week. With regards to quality, its important to keep framerate and resolution high enough that you can use the footage. Otherwise it becomes an expensive yet pointless exercise. -
I would suspect the vast majority of classroom projectors are maintained and installed using a ladder or table. Towers can be far more work and risk for small jobs like this. Think about getting one, moving it, putting it up, taking it down, clearing enough tables and chairs to get it in. Its about risk assessment and using the most suitable method available, and ladders for most 10 minute jobs are fine. The HSE says so. You would need to assess the risk of theft for the school in question. If its a difficult building to secure in a high theft area with known intruder problems, then taking them all down and putting them all back up again might not be much less work than sourcing and installing a schools worth of projectors in a hurry in September. If people really want your stuff, they will take it. We've had macs taken from a first floor classroom a couple of years back. Through the window, down a ladder. There was that school recently where they cut through the wall to get the ipads. Work with your insurance company and slt to make sure you have taken appropriate steps and its all good.

We had some performance problems on our oldest machines (Pentium D's), but then they're just slow full stop. Otherwise, we've only had a couple of user training issues.

We had a similar issue yesterday, but sgdClash instead. Our sims support people found this on support net:

We use Viglen, misco and cpc for the bulk of our stuff. Viglen have been very good at sorting problems and repairs. They do next day onsite - either an engineer, or just the part if we want to do it ourselves. One of the other schools in our federation uses stone, and I think they are happy with them as well. We've also been experimenting with some referb stuff from ICT Direct this year.

shapeways has a pretty good service. I've done a spare part for a motorbike using there service.

We use parent pay and have a PC setup at reception for parents to use. It doesn't get much use. We have cashloaders to go with our Vericool tills, so kids can still bring in coins and notes and put it on the system that way. We are hoping to move away from that though. You can also print off some sort of token to use at PayPoints in corner shops. We don't do uniform, but we do event tickets and textbooks through parentpay, so I guess its possible.
-
We mark most stuff over £50 or that is desirable for thieves - cameras, apple mice and dvd drives etc. We have found on some newer, more expensive plastics it doesn't etch properly. Viglen are able to do this for us on new PCs, but only the own brand stuff as far as I know. Having stuff nicked is a bigger pain in the bum, although how much this will stop a thief I don't know. We keep stuff till its really old. Never had any complaints from our recycling company. We don't sell it on.

can you connect via wifi / AI companion app? If you do that and scan the qr code, its much simpler. No messing with aistarter. AI starter and the emulator are a mess, but the rest of it works quite well.
-
Does the tablet have an internet connection? I don't know about the usb method, but if you use the wifi connection, it downloads the app from the app inventor website. Also, you might need the development drivers for the tablet or phone. Otherwise it might not show up. -- CORRECTION: it first connects to http://rendezvous.appinventor.mit.edu . Please see here: http://appinventor.mit.edu/explore/support/explain-wifi-connection.html The device then connects directly to your development PC to get the app. Both your PC and the tablet need to be able to get to the rendezvous website AND be able to commenicate with each other.

[voip] Single phone extension
Chris_Cook replied to Tricky_Dicky's topic in Mobile Devices & Tablets
Yes, but it might not work reliably if you do it on the cheap. It can also be tricky to configure - one of those projects you regret starting. We did this with 3cx, a grandstream phone, and a grandstream gateway. Have you got any Cat5 network cabling going there? you can run phones over cat5. Another option would be to get a sip trunk via your internet connection. You can have your external number ported to this. This might not work if you have a PBX on the line, but you can avoid the hassle of an analog gateway.
