Product Review – Brother ADS-2800W network document scanner

Previously, I reviewed the Brother PDS-6000 sheet-fed document scanner which scans both sides of a document at once very quickly. This model connects directly to a host computer and would work with most document-management software. Now Brother have released the ADS-2800W which is a network-capable sheet-fed document scanner that allows you to direct a scanning job to a computer or a file server / NAS, and this is the machine that I am reviewing now.

RRP AUD$899

There are some more expensive variants of this network document scanner that can scan at higher speeds but I am reviewing the entry-level model.

Single-pass document scan, easy to service if anything goes wrong

Brother have avoided the tendency to create a separate setup regime for the ADS-2800W network document scanner, which will be a bonus if you have stuck with this brand for your multifunction printer. Here, the software interface both at the scanner and at the computer are very similar and you can even use the ControlCenter 4 software to process your documents.

Wi-Fi connectivity

It was simple to connect this scanner to the home network although I used the Ethernet connection which is what I would prefer for normally-sessile devices. Here, it can be connected to a Wi-Fi wireless network segment or a wired Ethernet network segment (which also works with a HomePlug network segment) with the former network type working properly if nearer the wireless router. Personally, I would recommend that you use the wired network (Ethernet or HomePlug) at your home or office as I would recommend for sessile equipment.

Walk-up and mobile operation

Brother ADS-2800W network document scanner - Web services

It scans directly to Dropbox

There is the ability to use a Web-based interface to set the Brother ADS-2800W network scanner to be able to scan to a computer, file server or NAS without the need to run a scan monitor on that computer. Here, the unit deposits the files to a known directory on the destination device in a predetermined form. As well, it can be set up to “scan and send” where it can send a document via SMTP-based email.

It also exploits the Brother Web Connect infrastructure to allow you to enrol it with Evernote, OneDrive, Dropbox, Facebook and other online services so you can use them as a destination for your scanned documents. You can also scan documents and images to your mobile device as long as you run the Brother iPrint&Scan mobile app, which is how I scanned some snapshots to be destined to Dropbox. An improvement I would like to have would be to see the scanned picture appear on the scanner’s screen so you can have the picture or document the correct way up.

Computer-based operation

The fact that this scanner makes use of Brother’s ControlCenter 4 software and uses the same scan monitor if you are running a Brother MFC alongside it means that you are not having to install extra software on your computer. When I ran the CD to install the drivers because I had issues with the Website, the installer detected the existence of the driver software associated with Brother printers and effectively updated the scan monitor to work with this scanner.

I even had the software set up so that blank pages were skipped even though the Brother scanner scanned both sides of the document when I was handling regular documents. This allowed for a single-side document to be worked on yet be ready to scan double-sided documents when dealing with “print-sign-scan-send” documents.

Scanning results

The Brother ADS-2800W network document scanner, like its stablemate the PDS-6000 implements a straight-through document feed which makes the scanning job quick but is kind to the documents because there is no curved path involved.

A job that I have been putting the Brother ADS-2800W network document scanner to over the past week is to scan a collection of snapshots due to the passing of someone whom I knew well. Here, I had set the Brother scanner to scan at the normal-for-35mm-snapshots “10x15cm” size with a resolution of 600dpi and fed the minilab prints in vertically. The document scanner had turned out the high-quality images while it was able to handle small batches of prints at a time like as though I was handling a multiple-page document. But I would like to see a “photo-optimised” scanning profile that copes with the glossy snapshots and works at a high resolution. As well, there could be the ability to determine whether a photo has a landscape or portrait orientation.

I had found that a bit of dust had ruined a scan of a photo and it was a cinch to remove that bit of dust from the scan head simply by opening up the scanner so I can see the scan heads. Then I was able to blow off the dust from the scan heads.

When I scanned a regular “print-sign-scan-send” document, the Brother ADS-2800W scanner made light work of this job and turned out the right number of pages based on what was marked. This avoided the creation of a 2-page PDF for a document that was written on one side only.

Limitations and points of improvement

A feature that would benefit the Brother sheet-fed document scanners, especially the network-capable units, would be to have functionality that gains the best out of photo scanning. This could be in the form of a “photo-optimised” high-resolution scan mode for scanning snapshots and / or a transparent-media scan mode with negative conversion for scanning film strips such as negatives.

Conclusion

I would recommend the Brother ADS-2800W network sheet-fed document scanner as a network-focused high-speed document-scanning solution especially if you want a high-speed dedicated-purpose scanner that can work independent of a regular computer.

For example, this could work well if you destine documents to the like of Evernote or Dropbox or to a NAS. Similarly, if you are wanting to get that hard copy document to be able to be viewed on something like an iPad, the Brother ADS-2800W and its peers can do the job properly.

But these devices would earn their keep if you scan many documents rather than the occasional few documents that have few pages and I would see it perform well with most businesses including tax agents who scan the receipts that are part of their clients’ “shoeboxes”.

Windows 10 Tiles not functioning? You may have to restart Explorer

Article

Windows 10 Start Menu

If you are seeing blank tiles in this view, you may have to restart Windows Explorer

Windows 10 Tip: Fixing Live Tile Counts and Blank Tiles | Supersite For Windows

My Comments

If you are running Windows 10 and are enamoured by the “tiled interface” that is part of its Start Menu or Tablet Mode view, there are times where you may find it not working “up to scratch”.

With this interface, you may find that the Live Tiles that are regularly updated simply go blank or are stagnant. The normal response to this situation would be to restart your computer, which would then fix the problem.

Task Manager with Windows Explorer called out

The Windows Explorer process in Task Manager

On the other hand, you may only need to restart the Explorer process to fix this problem without the need to reboot your computer. This can also apply to other user-interface abnormalities.

Here, you run Task Manager by either right-clicking the Taskbar or holding your finger on the Taskbar in the case of a tablet or 2-in-1, then clicking Task Manager, or pressing Ctrl-Shift-ESC together on the keyboard. Then you find Windows Explorer in the list of processes. Right-click this item and click Restart and it won’t take long for it to come good.

Task Manager - Context menu with Restart called out

Click the Restart option on the context menu to restart Windows Explorer

At this point, the Windows Explorer process will recover and update the tiles including reloading the data that populates the tiles from its source rather than working of corrupted data.

How to effectively establish that Wi-Fi-based mobile network

Brother PocketJet PJ-773 Wireless Mobile Thermal Printer

Brother PocketJet PJ-773 Wi-Fi mobile printer – one of the mobile peripheral devices pitched to smartphone and tablet users

A major trend that has become strong over the last few years is the arrival of mobile network devices that connect to each other and to client computer devices via Wi-Fi wireless networking technology.

These are represented in the form of:

  • mobile network-attached-storage devices
  • mobile printers
  • wireless speakers, and
  • mobile broadcast-LAN tuners that work with terrestrial or satellite broadcast systems,
Network setup for mobile NAS and smartphone

Network setup for Wi-Fi-based mobile peripheral devices

What is common about all of these devices, and is treated as a key marketing feature by their vendors, is that they can be set up to be their own access point with their own DHCP server as well as being client devices to existing wireless networks. Some of these devices like most mobile NAS devices are able to work effectively as bridges or routers between an existing wireless network and the network that they create.

This may work well if you are just using the one mobile peripheral device with your mobile client devices but may not work well when you intend to run two or more mobile peripheral devices. Here, you will end up switching between different wireless networks just to benefit from the different mobile peripheral devices.

Mobile NAS as bridge setup

Wireless NAS as a bridge between mobile client devices and another Internet-providing network

But you may want to run one or more of these wireless mobile devices together to serve multiple laptops, tablets or smartphones. Situations that may come about that will call for these setups would be where you are using a mobile NAS and, perhaps, a camera that has Wi-Fi functionality or one of the new Wi-Fi-capable mobile printers. This will call for you to create a proper mobile wireless network for all of these devices.

Use a router-class device as the main device

Here, you would have to run one wireless network device as a DHCP server and “master” access point and this function can be best served by a router-class device.

"Mi-Fi" portable wireless router

A typical “Mi-Fi” portable wireless router for a mobile-broadband service

The most common examples of devices of this class that apply to “on-the-road” use are the “Mi-Fi” mobile routers that work with a mobile broadband service or one of the travel routers pitched to work with a hotel’s wired Internet service. Some mobile NAS devices may also do this wireless-bridging functionality in an adept manner and could be the hub of your “travel network”. Similarly, one of the mobile-broadband wireless routers being integrated in to some new cars by the likes of BMW and Chrysler may also answer these needs.

You may think of using your smartphone’s Wi-Fi mobile-broadband-router functionality but this may encumber your smartphone for what you want to really use it for.

Some highly-sophisticated “Mi-Fi” and travel-router devices may also expose an Ethernet connection for LAN use, perhaps through an optional extended-functionality dock. This can come in handy if you want to increase your coverage area with another wireless access point or want to use devices like games consoles with your mobile network.

You may find that you don’t need to run the Internet connection on the Mi-Fi or travel router if you are simply establishing a link between multiple mobile peripheral devices and client devices and aren’t reliant on Internet functionality for their operation. Similarly, by having your mobile devices working this way, you avoid the need to authenticate with a Wi-Fi hotspot that implements Web-based authentication to do something like gain access to your mobile NAS’s data from your iPad.

Set up known wireless network parameters

Mobile network wiht "Mi-Fi" router and 2 Wi-Fi-capable mobile peripheral devices

Mobile wireless network for two or more mobile devices and mobile client devices – uses a router-class device like a “Mi-Fi” router

When you set up your “Mi-Fi” or travel router, you make this device the hub of your mobile network and have every device “point” to this device’s local-network by associating with its SSID (wireless network name) and security parameters.

Most of the mobile network devices that work on an “open-frame” approach can be quickly associated to this “mobile hub” thanks to WPS-based push-button setup. For devices that don’t support this quick setup mode like most Apple devices, you will need to note down the “mobile hub’s” SSID and security passphrase.

For that matter, a good practice would be to assign a unique SSID for your “mobile hub” device i.e. your Mi-Fi or travel router. This is important when you use these setups in campgrounds, caravan parks or hotels where many of these devices will be used at once.

All wireless devices to link with router-class device

It will also mean that the mobile NAS, mobile printer or other similar device has to work as a client device rather than as its own access point. This also applies to your computing devices like laptops, tablets and smartphones which also associate with the “mobile hub” device.

When positioning your mobile-network devices, make sure that they are in the range of your “mobile network hub” device i.e. the Mi-Fi or the travel router. All the wireless traffic that goes between these devices will pass through the “mobile network hub” device rather than between the devices themselves.

You may find that if you want to avoid draining your “Mi-Fi” router’s battery too quickly, it may be a good idea to have it run from a USB charger that runs from house current or your vehicle’s cigar-lighter socket. Similarly, a high-capacity USB power-pack can also earn its keep with these devices if you are away from power.

What I stand for when reviewing or researching mobile devices

When I review any device for this Website that is capable of being its own wireless network such as a mobile NAS or mobile printer, I test the device with my home network’s Wi-Fi wireless segment as if it is a client device. This is so I am sure they can work in this kind of setup as well as the highly-promoted “own access point” setup. As well, as part of researching a mobile device that uses Wi-Fi wireless technology as part of its link with client computer devices, I verify that it can work as part of an existing wireless-network segment as well as being its own segment.

Similarly, when I research a mobile router-class device like a Mi-Fi or travel router, I would expect the device to support WPS single-push connectivity along with other essential Wi-Fi connectivity and security standards. Similarly, such a device would have to be easy to configure including setting up the SSID and passphrase. As well, the Mi-FI device can’t be very thirsty with its battery if the goal is to have it as a “hub” device.

Conclusion

Once you are able to set up a mobile multi-device network, you can then be able to use it to store or print data while you are “on the road” without needing to constantly switch networks for each different task.

Feature Article: Multi-Building Home Networks

I have covered the issue of bringing your home network and Internet service to other buildings on your property, whether they be a garage, barn or granny flat (mother-in-law apartment).

You may consider this as being of value to, for example, achieve a quieter house by having your teenagers playing their video games in the converted garage; bringing Netflix and similar services to the man-cave or just simply allowing whoever is sleeping in the guest-house to have access to the Internet.

Europeans will benefit from the fact that one right-sized satellite dish could cover your property’s satellite-TV needs including the ability to watch from that granny flat thanks to SAT>IP technology that exploits your home network as a satellite-antenna link.

This will provide what I have been talking about as a single diagram that you can understand.

Buying a projector for your small business

Some of you may be buying a projector for the first time such as to add large-screen video display to your organisation’s presentation abilities; or you are replacing your existing video projector that has got a bit long in the tooth.

Praise and worship at church

Choosing the right projector can allow a church or other organisation to gain the most mileage from it

But when you are considering the purchase of a projector, take time to consider where you are intending to use it and what you are using it for.  This will make sure you are going to end up with a machine that can satisfy your needs exactly by projecting the brightest and sharpest image where you are using it.

What to look for

There are certain attributes that you need to look for when buying that projector such as its brightness and contrast-ratio specifications along with factors that affect how you can install your projector.

How your projector’s image will look

Brightness (lumens)

This specification affects how bright the images that appear on the screen will be. A projector with more lumens is also able to deal with competing light sources like room light easily. Today’s office projectors will typically end up with a brightness of at least 3000 lumens.

It is worth noting that a projector will yield the quoted brightness when it is using a relatively-new lamp and set to operate at full brightness.

Video and photo material along with games places more demands on the visibility of the image especially in existing light compared with graphic material that changes infrequently. This may call for a projector to have increased brightness. As well, you may have to look for a projector with increased brightness if you aren’t able to control the ambient lighting especially for video or photo content such as with rooms that have a lot of natural lighting.

The rule of thumb here is to buy the brightest machine you can afford no matter how small or brightly-finished the room is. This is more important if your room has large windows and you have a view to using the projector there during the day such as hospitality applications; or you intend to run the projector with the room’s lighting switched on which is the reality with most business or worship applications.

Contrast Ratio

This specification identifies how dark the black parts of an image will be and how white the white parts of that same image will be. It may influence the “perceived sharpness” of the projected images.

How your projector will “fit in” to your venue

There are certain specifications that concern how far back you have your projector from the screen or wall you are projecting the images on in order to have the largest useable image.

Throw Ratio

Projector setup diagram with distances

Throw distances and ratios explained in a projector setup

The projector lens’s throw ratio determines the effective size of the projected image in relation to the “throw” which is the distance between the projector’s lens and the screen. A lower figure allows for the projector to be closer to the screen for the same image size than a higher figure.

A projector that has a zoom lens, like most of the equipment pitched at small businesses and community organisations, will be specified a minimum and maximum throw ratio that is determined by the focal length you set the lens to. The zoom lens may help you with getting your image “just right” for your setup after you position the projector for best image size.

The “standard” throw ratio for most office and classroom projectors will come in at between 1.5 and 2.0 while a short-throw projector will come in at between 0.5 and 0.7. The newer ultra-short-throw projectors typically have a throw ratio of 0.3, allowing you to position them very close to the screen.

When you choose your projector, a short-throw projector can earn its keep in small rooms or for portable / temporary setups. These machines can earn their keep if you want your projector to be “ahead” of your audience. There are environments where an ultra-short-throw projector can come in handy like a small room such as a classroom, or a permanent installation for a space which gets crowded very quickly like a bar. Similarly, you may find that your venue has a bulkhead near the screen’s location where you can feasibly mount your projector, which may call for an ultra-short-throw model.

Projection Distance

Manufacturers will also provide a minimum and maximum projection distance specification in order to specify how close to or back from the screen the projector should be to yield a useable bright image.

But your setup’s “throw distance” will be based on the throw ratio of your projector’s lens multiplied by the width of the screen and this should be within the distances specified for the projector you are using. Once you know this figure, you can then determine how far back the installation’s ceiling bracket should be positioned.

Aspect ratio and Resolution

A projector, like a digital camera, is specified with a native aspect ratio which is the aspect ratio for the actual LCD or DLP image panel that realises the pictures. As well, they have a maximum native resolution that the LCD or DLP can handle for best results.

The "pillar-box" effect when you show 4:3 material on a natively widescreen display

The “pillar-box” effect when you show 4:3 material on a natively widescreen display

They can handle other aspect ratios but will yield “letterboxed” or “pillarboxed” images which have the black borders at the picture’s edges. You may have noticed this effect when you watch television and you watched some newer widescreen content on your old TV or you watched older TV content on your newer flat-screen LCD TV. In this case, you would need to determine your screen size based on the projector’s native resolution.

A projector with a wide native aspect ratio like 16:9 makes better use of wide screen areas whereas a projector that uses 4:3 as its native aspect ratio may work well for narrower screen areas including “traditional” screens.

Native 16:9 projectors are important if you are regularly showing live TV, movies or other video content turned out in this ratio; as well as yielding that wide look that easily impresses. You can get away with a native 4:3 projector if you occasionally show video but show a lot of graphics material or digital photos prepared in this ratio. It is also worth knowing that projectors that have a native 16:10 aspect ratio may allow for some flexibility between allowable screen area and what you show and is a go-between for 4:3 and 16:9 as well as accommodating scanned 35mm slides and prints.

As for the resolution, I would work towards projectors with a vertical resolution of at least 768 lines even for business applications. 16:9 projectors with the 1920×1080 “Full HDTV” resolution would earn their keep with most of today’s TV and video content, especially if you are running them with an HDTV set-top box or Blu-Ray player.

This is important because your audience will want to see a very sharp clear picture and the eye is less forgiving about fuzzy or blocky images on the big screen.

Connectivity and Functionality

Essential Connections

Economy data projector with VGA input sockets

Nowadays a projector should have an HDMI socket for newer computer and video equipment as well as a VGA socket for legacy equipment

Make sure that the projector that you are after has at least an HDMI input with HDCP for today’s computer and video equipment along with a 15-pin “VGA” RGB input for older computers that don’t use this connection.

If you intend to use your projector with consumer video equipment especially the Apple TV box or pay-TV services, make sure that the HDMI connection supports HDCP content projection. As well, a projector that implements HDMI-CEC control functionality can be a real boon with providing “one-remote” operation with most consumer electronics equipment especially Blu-Ray players.

Integrated image/video projection functionality

An increasing number of projectors are being equipped with the ability to display images and video footage held on a USB memory stick, onboard memory or other media which can make them become today’s equivalent of the old movie and slide projectors. This feature can be used for “there-and-then” applications or where you can’t connect a computer to the projector and is highly relevant to portable applications.

Sony BDP-S390 Blu-Ray Disc Player

Most recent Blu-Ray and DVD players can show still and video material from USB storage devices

On the other hand, if you don’t want to use a computer to show pictures or file-based video content, you can use a recent DVD or Blu-Ray player, network media player or similar device to fulfil this role.

Wireless and network projection

Another feature that is available with an increasing number of video projectors is the ability to project images from a computer or mobile device via a network, a dedicated Wi-Fi link or a Bluetooth link.

Most of these implementations are very dependent on the client device running particular software or the purchase and installation of certain interface devices. At the moment, Miracast and Intel WiDi are considered stable standards in this space but you need to be sure if there are other implementations that are able to work across devices offered by multiple manufacturers.

On the other hand, there are video-peripheral devices like the Apple TV and the Google Chromecast which can answer this role effectively. This is more so if you want native network-projection support from iOS and Mac OS X devices in the case of the Apple TV or Android and Chrome OS devices in the case of the Chromecast.

Audio

Most projectors will have an integrated amplifier and small mono speaker for sound reproduction and many will have an audio DAC if they are equipped with an HDMI connection. This is good enough at a pinch but I would rather use a powerful sound system such as a hi-fi, home-theatre or PA system for reproducing the sound.

It is also worth knowing that most of the projectors with an integrated amplifier and speaker will have a stereo line-out connection, typically in the form of a 3.5mm stereo phone jack. This comes in to its own with HDMI-equipped projectors that reproduce the sound from the HDMI connection and earns its keep if you have the sound system located close to the projector so you can keep a short unbalanced analogue audio link between the projector and the sound system’s amplifier.

If you want the sound to be reproduced independently of the projector such as to play music without a visual display, you may have to either connect your computer directly to the sound system or use an HDMI audio-extractor also known as an HDMI audio adaptor or HDMI DAC for best results with your sound system.

Lamp life

A projector will have its lamp life rated based on how long the machine will continuously operate before the lamp is half as bright. This is against the common logic of rating the lamp life based on how long it will operate before there it “blows” (burns out). I still factor in the reliable operation angle in that same equation. This specification is based on having the projector run at full brightness but being treated properly.

But most of today’s projectors implement lamp-management logic to effectively run the lamp for a longer service life. Examples of this include offering an “eco-mode” or similar setting to run the lamp at reduced brightness, tapering the lamp’s brightness slightly when the projector is showing the same image for a long time or some even adjusting brightness based on room lighting.

Problem can still surface with some projectors where the lamp lasts a long time but hits the end of its useful life and a good quality replacement isn’t available for that machine anymore. This can happen when a manufacturer makes equipment that is less “parts-common” with prior models when it comes to user-replaceable parts and it could be more financially viable to replace the machine with something of a similar or better standard when the bulb comes up for replacing.

Solid-state lighting (“lamp-free”) projectors

An increasing number of manufacturers are offering projectors that implement solid-state projection lighting which implements LED and/or laser-diode lighting technology. This is compared to the common practice of using a bulb-based lamp and allows for lower maintenance requirements. Manufacturers call these projectors “lamp-free” by virtue of not having to factor in the risk of the projection lamp “blowing” and stopping the show or you having to keep a spare lamp on hand.

These projectors offer best value for installations like displays were you are likely to have the projector running constantly. In other cases, you can get by with a projector that implements the regular light-bulb technology.

Buying guidance

When you choose your new projector, buy a projector which has as high a lumens rating as you can afford and look towards units with at least 3000 lumens. This is more important if you intend to use it in settings where you intend to run video content or show photographs in ambient lighting or your environment is brightly finished or has plenty of natural lighting.

Look towards purchasing projectors that support a 16:9 or 16:10 native aspect ratio unless you are using a narrow wall space as your screen.

Short Throw or Ultra Short Throw projectors earn their keep with small rooms or where you want the projector to be in front of the audience.

If you expect to frequently run your projector for long sessions, like a display, a worship scenario, or a bar that is showing the big sports fixtures every weekend, look for equipment that has a very long lamp life. If you can afford it, you may want to consider a projector that implements solid-state “lamp-free” technology.

Making sure your projector lasts a long time

You will typically get around five to seven years useful life out of a good-quality projector if it is operated and maintained properly.

To achieve this, make sure that the machine is on a sturdy surface before you turn it on. This also is of importance if you are using something to raise the front of the projector slightly to get the picture right. As well, transportable projectors have to be handled gently especially when they are on or just been turned off. If you are setting up an integrated installation, make sure you are using a good-quality mount kit and that it is anchored properly to the mounting surface.

At the end of each session, make sure that the projector is properly shut down so that the lamp isn’t damaged by excessive built-up heat. This procedure is more important for transportable units or units that are in an installation where they can be enclosed when not in use like “drop-down” installations. Here, you have to turn off the projector using the standby button on the unit’s control panel or its remote. At this point, the lamp and the circuitry associated with the projector’s signal path are turned off but the fan will continue to run for a few minutes. Depending on the machine you are using, an indicator light on the projector will flash or glow to let you know that this is taking place. This cool-down process is completed when the fan shuts down and only the “standby” indicator glows or no lights glow depending on the machine.

Avoid the temptation to turn the projector on and off too frequently because this can shorten the projection lamp’s lifespan. Here, if you need to have nothing on the screen such as when loading up subsequent content, use the “Mute” or “Blank” button on the unit itself or the remote; or a similar function on your display computer’s software to achieve this goal.

If your projector uses filters, make sure you change them on a regular basis. As well, it is a good idea to clean the ventilation grilles to stop dust building up in them. This may simply be a case of running your vacuum cleaner’s crevice nozzle over these grilles; and is more important in dusty areas.

Be aware of how your projector fan sounds when you are using your projector. If you hear excessive grinding or squealing noise, this is an indication that the fan’s bearings are on the way out and it could cease to do its job. It leads to unreliable operation and heat build-up which could shorten the lamp’s lifespan. This may be a time to send the projector to a repair workshop and have the fan replaced.

The screen you use for your projector

The other factor that you also have to consider when you buy a projector, especially for the first time, is the screen on which your projected content will appear. This may not be of concern if you are simply replacing an existing projector with a newer model.

Fixed Screens

Some of you may use a white wall or whiteboard as a fixed screen for your projector when you are on a budget or, in the case of a whiteboard, you intend to implement an interactive-whiteboard display.

On the other hand, you may purchase a dedicated fixed screen that mounts on the wall or on an adjustable bracket.  Wall-based setups will occupy wall space even when they aren’t used and you may use doors, shutters or curtaining that complement your décor to conceal the screen when it is not in use. The adjustable-bracket setup will earn its keep with classrooms, worship applications and the like where you have a main focal point of attention.

Here, it would be preferable to have a fixed-screen setup if you have a permanent setup or can keep unencumbered wall space available for a screen.

Retractable and Portable Screens

But, if you don’t have that wall space, you may find that you have to purchase a retractable screen of some sort.

Portable screens

These come in a portable form that either is the classic tripod screen that most of us are familiar with or a “pull-up” screen which is a simpler larger form with the screen coming out of a large tube that sits on the floor or table. Some of the “pull-up” screens may be designed so that they can be attached to a wall, bulkhead or other similar feature on a temporary basis so they are effectively portable pull-down screens.

Fixed retractable screens

A presentation shown on a retractable screen

On the other hand, you have fixed retractable screens that have a roll that is permanently mounted.

These screens, commonly described as “roll-up” or “pull-down” screens, are pulled down like a traditional roller blind when they are needed. They can be mounted with the tube that the screen rolls into exposed or this tube can be concealed, whether in the ceiling or a specially-built pelmet with the screen emerging from a slot in the ceiling or pelmet.

There are some more expensive varieties that extend and retract under electric control but are more suited to permanent installations. These may look more elegant and opulent but you will also find that they last a lot longer because they are less subject to the manhandling that a typical manual roll-up screen is subjected to. I would recommend this type of pull-down screen for those venues where the equipment is expected to gain a lot of regular use.

What to look for here

Here, you need to place importance on the screen’s build quality because this affects both durability and image quality. This is more important with retractable and portable screens when your screen will be set up and put away by many different people such as what happens if you have a high turnover of staff or volunteers.

As well, when you buy that portable screen in a “bricks-and-mortar” retailer, try to set it up and pack it up yourself before buying it. This will allow you to identify if it is well-built and can be easily set up or packed up by an inexperienced person, something expected of in volunteer-driven organisations like churches, or businesses like bars or cafés which have a high staff turnover rate. You also have the chance to see how stable the screen is once it is assembled in order to be sure of a high-quality picture and less need to adjust the projector during a showing.

It is worth paying attention to the fabric that the screen is made of. A heavy fabric or a lighter fabric that uses tensioning at the edges leads to high-quality images especially when you intend to use it with ultra-short-throw projectors. You can get away with a matt-white screen finish when you are using today’s video projectors so avoid being sold the exotic finishes like glass-beaded surfaces if you want to save money.

Conclusion

Whether you are replacing an existing projector or are buying a new projector and screen setup for your organisation, it pays to take some time to purchase the right equipment for your needs rather than rushing in to it. This will allow you to see a highly-reliable setup perform for many years of use.

Cable One pushes towards a Gigabit Arizona city

My Comments

In some areas, a small firm focuses on providing next-generation broadband to those areas, whether be FTTC fibre-copper (VDSL2), FTTP fibre-optic or HFC fibre-coaxial. This allows them to concentrate on enriching those areas’ Internet service and has been taking place mainly in rural UK.

Now this practice is taking place in some parts of the USA, especially Arizona, thanks to Cable One. Here they have rolled out in to Cottonwood and Clarkdale a DOCSIS 3.0 HFC service which can yield 1Gigabit/second downstream and 50 Megabit/second upstream. The cost of this service, known as Gigabit One, will be US$175/month with a 500Gb data plan, but will make sure it is able to be delivered across all of both towns. There are other plans being put up for this service including one that has a 2000Gb allowance.

It is the first of the cable-based firms to offer a Gigabit service and has been seen as a way to call those small towns “Gigabit cities”. But the idea of smaller companies focusing on smaller neighbourhoods allows them to concentrate on making sure that these neighbourhoods can benefit from current technology and may even allow larger businesses to set up shop there especially when they want to encourage telecommuting.

Sony SBH-52 Bluetooth Headphone Audio Adaptor

The Sony SBH-52 Bluetooth Headphone Adaptor – OLED display to show time or details about what’s playing like the SteelSeries Rival 700 gaming mouse

Regular readers may have read my review of the Sony SBH-52 Bluetooth headphone audio adaptor which implements a monochrome OLED display to show the time or metadata about what what’s playing. Sony has also implemented this concept in a few previous personal-audio players as well as this Bluetooth headphone adaptor because of the fact that this display technology doesn’t take up much room in the device itself and could be best described as a “VFD display for battery devices” where it offers the same brightness as a vacuum fluorescent display while drawing minimal current.

SteelSeries Rival 700 gaming mouse – OLED display

SteelSeries have taken this further by implementing a user-customisable OLED display on the Rival 700 gaming mouse. Here, this mouse uses a special program to copy over game stats or a user-defined logo to appear on the display courtesy of the USB connection. Here, it is proving the idea that an OLED display can earn its keep on a small portable device even if the device is powered from another host device.

The Rival 700 gaming mouse also implements tactile feedback during gameplay so you can benefit from that convincing game effect but it is achieved in a manner to avoid disturbing your gameplay. As well, the mouse is designed for increased durability so you can subject it to intense gameplay or office work and SteelSeries offer it as something to equip your gaming rig or workstation for AUD$100.

Google’s Project Ara modular smartphone is for real

Google Project Ara modular phone - for real

Google Project Ara modular phone – for real

Google’s Project Ara: build your dream phone | The Age

My Comments

There has been some previous coverage about Google’s “Project Ara” modular smartphone, but there was some doubt about this phone being for real.

This mobile phone, like the LG G5 smartphone, can be improved by you buying and adding extra modules that offer additional or better functionality. It is very similar to how the IBM PC evolved where it was feasible to add on extra parts to improve the computer’s functionality.

Google had put the Project Ara concept smartphone on the slow burner and LG advanced their take on a smartphone in the form of the G5 having an improved camera or a hi-fi-grade audio DAC module available as options. Now they have come forth with a firm proof-of-concept to be offered to developers so they can design the modular hardware and to have a system ready for the masses by next year.

Google will push the idea of requiring the modules to be certified by themselves in order to assure quality control and the user experience for installing or upgrading any of these modules will be very similar to replacing a microSD card in your Android smartphone. This is where you tell the operating system that you wish to remove the card before you open up your phone and swap out the card, something I do with my Samsung phone when I want to play different music because I see the microSD cards as though they are cassettes or MiniDiscs that contain music ready to play.

Like with computers, the modular phones will still appeal to those of us who are tech enthusiasts and don’t mind customising our phones to suit our needs. Personally, I would like to see this same modularity looked at for tablets, 2-in-1s and laptops pitched at this same user class who values modularity and customisability.

You can still claim the Windows 10 free upgrade after July

Making Sure You Are Eligible For The Windows 10 Free Upgrade Before It Expires | Supersite For Windows

My Comments

Windows 10 Free Upgrade screen

This is where you will reserve your copy of Windows 10

Microsoft is terminating the free Windows 10 upgrade offer for Windows 7 and 8.1 users in July but you may be able to reserve that upgrade and “make hay while the sun shines”. This can be achieved by you clicking on the Windows 10 icon in the Notification tray and going through the processes as if to upgrade to effectively reserve that upgrade for your current hardware.

But if you want to stay with your current operating system, you would have to roll back the update so that you and your current computer are effectively registered with Microsoft as if you have taken advantage of the free upgrade. You can also supply the Windows Product Key for your existing operating system in order to reserve your copy of Windows 10.

Some of you who are in the market for a new Windows-based computer may want to skip this process and focus on benefiting from Windows 10 whenever you have your new computer. But if you are “spinning out” your older computer as, perhaps, a secondary computer existing on your home network while you are buying the newer unit it would be worth proceeding with the upgrade. On the other hand, you can download and apply Convenience Rollup Updates from Microsoft to effectively keep the older computer to a similar security standard as the newer equipment.

Similarly, you could download the Windows 10 Media Creation Tool from Microsoft which allows you to create an optical disc or a USB stick as an installation / upgrade media source, then use this tool to deploy the Windows 10 update on to your computer. You could do this as part of registering your computer with Microsoft to reserve the free upgrade.

Cleaning up online advertising: Google and Bing make life hard for undesirable advertisers

Article

Advertising of predatory financial services

Google Will Start Banning All Ads From Payday Lenders | Mashable

Advertising of online tech-support scams

Bing brings in blanket ban on online tech support ads | Naked Security

My Comments

Google clamps down on advertising of predatory financial services

An issue that has caused a lot of concern with the Global Financial Crisis is the existence of predatory sub-prime financing services like payday and other short-term loans. This issue has been raised as a civil rights issue as well as a consumer-protection issue because predatory lending occurs more with disadvantaged communities and the kind of loan products charge exorbitant amounts of interest.

Google has attacked this issue by prohibiting payday and similar lenders from advertising through their Adwords search-advertising platform. As far as I know, it doesn’t affect any of Google’s display advertising services like Adsense or Admob. This follows similar action that Facebook had taken concerning their online advertising platform, with both these companies being the biggest online advertising platforms encompassing both their own properties and the ad networks that serve other publishers and mobile app developers. It is part of Silicon Valley’s reaction to contemporary issues of concern like civil rights.

This will effect the advertising of loan products that are due within 60 days or have an interest rate of 36% or more in the USA. But the issue that may surface is whether Google will apply this rule to their display advertising networks and if other online advertising services will follow suit and apply it across their products.

Bing clamping down on online tech-support scams

I have given a fair bit of airtime on HomeNetworking01.info about the online tech-support scams due to hearing from people in my community who have had near misses with these scams.

This typically manifested in the form of the phone calls that people received from someone pretending to be the tech-support team associated with a respected IT or telecommunications name, stating that the user’s computer has a virus or something else is wrong with the user’s computer hardware or software.  But they lead you to establish a remote-access path to your computer so they can “fix” the perceived “problem” or “threat” for a fee, with these scammers making off with a large sum of money or installing software of questionable provenance and relevance on your computer.

Most of us have become aware of these scams through the various customer-education efforts by the IT community and consumer-protection organisations, encouraging us to seek IT support from people whom you know and have met in person like your business’s IT department or the IT experts in your household, family or community.

This has led to computer users not answering these calls or simply hanging up when they receive those calls. Now the scammers’ MO has changed towards cost-per-click Web ads or popups that flash up warning messages saying that your computer has problems and instructing you to call a toll-free number. This plays on the fact that you are seeking a problem to be rectified by placing that phone call.

Bing Ads, which is part of Microsoft’s Bing search platform, have banned the advertisement of third-party tech-support services because of the quality issues that are affecting end-users’ data safety. There has been an unintended consequence from this ruling which has made it hard for honest IT-support providers to advertise their services on that platform.

Conclusion

I see it as one of many efforts by the online advertising industry to clean up its act and gain the same level of respect as traditional advertising but there could be a more uniform approach to the problem of questionable online and mobile advertising.

The only way I see this coming about is for the industry to adopt a code of practice with conformance being indicated to end-users, publishers, content-filter software and others through distinct trademarks and symbols. This could address issues like advertising that is allowed, the kinds of ad contracts offered including the tenure of these contracts and the kind of payment received, due-diligence requirements, and liaison with law enforcement, customer protection and other authorities.

I have provided some previous coverage about the issue of native client apps that run on desktop operating systems for messaging platforms. As I have highlighted in the article, I underscored the performance issue which will benefit heavy multitaskers and gamers, the ability to work tightly with the operating system’s functions and abilities and the existence of 2-in-1s and ultraportable computers as a viable alternative to mobile-platform tablets.

.. or your Apple Macintosh computer

The regular computer was the class of compute that benefited from the instant-messaging app but mobile-platform smartphones and tablets took over the role of personal-communications devices with the different messaging platform vendors focusing on these devices as their terminal of choice. Skype and Viber have kept the desktop (regular-computer) usage case alive and now Facebook offered a Windows 10 desktop native client for their Messenger platform.

for secure online communications so you don’t have to rely on your smartphone or tablet

Now WhatsApp have answered this call for their secure communications platform by offering native clients for the Windows (8+) and MacOS X (10.9 Mavericks + ). Like with Viber, these desktop native clients are pitched to be a secondary user interface for your WhatsApp account that is set up on your smartphone. This means that once you install WhatsApp on your Windows PC or Mac, you then have to bind the desktop app to your WhatsApp account by using your smartphone’s WhatsApp client to scan a QR code shown on your regular computer by the desktop WhatsApp client.

For WhatsApp users, using these native clients rather than the WhatsApp Web application means that you have the benefits of this platform on your regular computer without the unnecessary overhead that the typical desktop Web browser can impose on your session. Nor do you need to keep a Web-browser tab or session open for desktop-based WhatsApp communication.

This is a sign that regular desktop and laptop computer users, including multitaskers and gamers, are not being forgotten about when it comes to mobile messaging networks.

The CSIRO considers the Internet Of Things a viable alternative to the alarm pendant

Article

Why the CSIRO is building smart homes for elderly Australians | IT News

My Comments

The typical situation to assure the welfare of an  elderly, disabled or chronically-ill person who is living alone at home is to have them wear a pendant or wristband panic-button that signals carers or loved ones if they need help.

But issues have been raised about these devices being, for example, left somewhere in the home because the person forgets to wear it after they have finished an activity which may not play well with these devices. As well, these wearable devices are only of value if they trigger the device in response to an emergency situation like a fall.

The CSIRO are looking towards the use of the “Internet Of Everything” as a way of monitoring the welfare of these people, a use case which I do frequently refer to in the context of this technology.

Here, they would use commonly-available sensor technology like the motion sensors that are part of every intruder-alarm system, or flow meters and power meters on appliances; or door-contact sensors on wardrobes or kitchen cupboards to observe for normal activity.

Along with this, the CSIRO effort also wants to use health sensors like blood-pressure monitors or scales to register a person’s health statistics and it has been valued because the patients will be wanting to know how they are doing along with the ability to provide more knowledgeable information to their doctor about their symptoms.

They want to use knowledge of past health incidents affecting elderly, disabled or chronically-ill people to train the machine-learning algorithm to identify the abnormalities at an earlier stage rather than when a serious incident occurs. Of course, any machine-learning setup needs to be able to adjust to newer legitimate changes so as to avoid any “false positives”.

A question that will always be raised is the cost to set up this kind of observation with it costing less than AUD$3000 because of the use of common technologies and components rather than specialised hardware.

The topic of privacy has also been raised because the CSIRO monitoring system is based on cloud technology and Internet-based data access, and is of importance to reduce the risk of elder abuse. Here, the goal is to allow the patients to control their data so that it is exposed to whoever they trust in a granular manner. This is more so with relatives because they may be trusting of certain people within their family.

As well, the features that have been raised as being of importance to the elderly community for this personal-health monitoring setup include the ability to know who is at the door, the ability to engage in videocalls with family and friends along with the ability to know if one has forgotten to turn off a tap or appliance. This can easily affect older people who may become increasing forgetful about these things such as a burner on the newer gas cooker being left on but turned really down or not being able to hear clearly that the washbasin tap is still running.

The effort that CSIRO is undertaking is to be able to allow an elderly or other vulnerable person to live independently yet be able to know that help is at hand while their loved ones are sure that they are well.

Increased value for money affecting residential broadband in Germany

Article Flag of Germany

50 MBit/s und mehr: Verbraucher wollen immer schnelleres Internet | Computer Bild.de (German language | Deutsche Sprache)

My Comments`

Recently, German households are gaining better value for money when it comes to purchasing broadband Internet service. This is affecting the higher-speed 50Mbps service packages that are being preferred by the younger people.

German Internet customers preferring better value for money for their “50Mbps Talk and Surf” service

These plans are being underscored by their availability as part of multiple-play communications-service deals which include fixed or mobile voice telephony, broadband Internet along with other services. In Germany, the service package that is commonly preferred is the “double-play” service, marketed as a “Talk & Surf” service that encompasses a fixed-line telephone service and a broadband Internet service.

The article highlighted an increase in the preferred connection speed for the broadband services over 5 years with households showing strong interest in the 50Mbps services rather than the “economy” 16Mbps services. As well, the average cost of a fixed-line telephone + broadband service in that country had been dropping slightly from EUR€35.73 per month now to EUR€28.82 per month.

It is being underscored with the increased availability of better-value 50Mbps services in Germany’s larger cities but the 16Mbps “economy” packages are being found to have reduced value for money and this price drop is being described as being a slow one. As is often noted, this kind of value for money when it comes to Internet service doesn’t extend to rural areas which tend to find themselves at a disadvantage in this field.

Personally, I would attribute the increased ubiquity of VDSL-based Internet service in Germany’s urban areas being a factor leading to the improved value for money when it comes to the higher-speed packages.

But the questions to raise regarding the German broadband market is whether there is significant infrastructure-level competition in that country? Similarly, the availability of retail-level competition for residential and small-business telecommunications services has to exist at a sustainable level to assure customers best value for money.

At least something is happening for German households where they are gaining better value for money with their Internet services.
