Introduction

I had decided to upgrade my Bluetooth headphone adaptor which was the Nokia BH-111 to the Sony SBH-52 Bluetooth Headphone adaptor, with a view to head towards some newer capabilities that these devices have. This is also to benefit from various improvements like multipoint operation, aptX audio codec for high-quality music and HD Voice codecs for improved mobile telephony services.

Price

RRP: AUD$159.95

Specifications

The Bluetooth adaptor itself

The Sony SBH-52 Bluetooth headphone adaptor comes with a pair of in-ear earphones but can be used with any headphones that you wish such as your good Bose, B&O, Sennheiser or Skullcandy “cans” or a set of noise-cancelling headphones for that flight or train trip. It also works as a Bluetooth handset or speakerphone which would come in handy with a computer that is running a softphone application.

Touch your NFC-capable phone on the clip to pair it with the headphone adaptor

For setup, you can pair up an Android or Windows device with the Sony headphone adaptor using NFC “touch-and-go” pairing by touching the device to the headphone adaptor’s tie clip. But you would have to hold down the POWER button at the end to make it discoverable if you were to pair it with a device that doesn’t support this kind of pairing like all of the Apple devices.

It presents itself to the host device as a Bluetooth Hands Free Profile device and a Bluetooth A2DP audio device with support for aptX high-quality sound for music and HD Voice codecs for communications. It also works to the AVRCP 1.4 device-control standard with the ability to show the title and artist of the currently-playing song when used with a device that supports this level of functionality.

You can even pair this Bluetooth headphone adaptor with two devices and set them up in “Multipoint” mode so you can run them at once. For example, you could pair with two smartphones such as your work phone and your personal phone and answer calls on either of them using its handset button. Similarly, you could pair it with you desktop or laptop computer running a “virtual-extension” softphone app or a Bluetooth-enabled desk phone alongside a smartphone and manage calls from both these devices.

The SBH-52 as an FM RDS radio

As well, the device serves as an RDS-equipped FM stereo radio but you will need to use it with your headphones because the headphone cable serves as its FM aerial.

But the Sony SBH-52 shows its real capabilities when you use it with your Android smartphone because of a Sony “Smart Connect” app, something I see as Sony’s “love-letter” to the open-frame Android mobile-device platform. This works as a “go-between” for messaging, Facebook, GMail and some other services through the use of downloadable “extensions” that you pick up from Google Play. It also becomes a watch showing the current time when you have it switched on and connected with the Android smartphone running this app.

Operational Experience

The Sony SBH-52 as a digital clock for your Android phone.

I have found that the Sony SBH-52 Bluetooth headphone adaptor clips to your shirt or tie without any issues whereas the older Nokia BH-111 had difficulties with clipping to thicker materials present in winter clothing or premium ties. This is due to the use of a clip that works in a similar manner to the old clothes-peg or the clip on an old-fashioned clipboard.

One issue that I have noticed at times is for the Sony SBH-52 to lose its connection with the phone if there is a period of inactivity. It can also manifest in the form of the on-screen data being out-of-sync with what is playing or whether the music is playing at all. This can be rectified by you powering the Bluetooth adaptor off and on or pairing again with the host device and may be a problem with the particular Android Bluetooth software in the Samsung smartphone.

The call-log function wasn’t all that consistent – it was able to show the caller’s name or number for whoever rang in or whoever I rang, but I couldn’t ring that caller back from the Bluetooth audio adaptor. Here, I would see the option to call back on the screen, with the “Yes” or “No” options, but couldn’t action these options using the Play/Pause key. This may be an issue if you haven’t set a particular call handler to be your default call handler on your Android phone.

A problem that can also happen with this headset and other Bluetooth headsets or hands-free devices is if you run a VoIP client like Viber or Skype on your Android phone, you can’t answer the VoIP client’s calls using the headset’s call-control button. This can be awkward in those situations where hands-free operation is desireable or paramount such as driving, walking or cycling. It is something I had found to my chagrin that I couldn’t answer an incoming Viber call using the SBH-52’s call button and had to use the Viber user interface on my Samsung phone to take that call.

The sound from your phone’s media player comes across as good as what the phone and headphones allow. Of course, you may notice a sense of clarity in the sound that it yields.This occurs with both the Bluetooth music and phone calls along with the radio. Of course, it will exhibit the limitations of the FM band which are similar to what is expected of Walkman-style FM radios, such as inconsistent FM reception in hilly or forest areas or city-centre areas with many tall buildings. But it was able to stay locked on to whatever I tuned it to without drifting.

The SBH-52 headset works properly with my Windows 8 computer, even providing elementary AVRCP-level control of media players using its media-control buttons. As well, when used in the Multipoint mode, each of the two devices is treated as a “source” in context with music and audio-content playback.

As for battery runtime, I was able to obtain one and a half days of music-streaming with a few phone calls out of this device before it needed to be recharged. As well, it was able to come from being empty to a full charge overnight once hooked up to an ordinary USB charger. Here, I could use any old microUSB-USB charge/data cable to connect the SBH-52 to a computer or charger when the time comes to charge it up.

Limitations And Points Of Improvement

The software for the Sony SBH-52 headset adaptor could be worked on better such as to allow the connection between it and a previously-paired Android host device to be properly healed when you switch it on and press the “play/pause” button. It could also make sure that it intercepts all incoming-call events from other Android VoIP apps so you can take calls on the headset.

The FM radio leaves a lot to be desired when it comes to functionality. One important function that is sorely missing is the ability to have preset stations. Similarly, the RDS aspect could be improved on, such as to have the PS station-identifier information shown in lieu of the frequency like what happens with automotive implementations. Even implementing the AF “follow-me” functionality that is used in Europe to automatically tune between different transmitters for a network station could earn its keep with travellers who use this while travelling across a country or region.

Sony could sell a variant of these headphone adaptors which is equipped with a DAB+ radio tuner for Europe, Australia and other countries where DAB or DAB+ digital-radio service is operational. It is more important with those markets like Australia where the AM radio stations which carry information-based radio content also appear on DAB+ digital radio while also underscoring DAB+ digital radio’s robustness for portable use.

Sony could extend their Bluetooth headset adaptors’ functionality by providing native support for the Bluetooth MAP messaging profile so that all text and other messages that come in show up on the adaptor’s display. As well, they could implement the full Bluetooth Handsfree profile with its call-control features in the headset adaptor natively without the need to run extra software. This means support for call-log abilities and access to platform-based “voice-assist” functionality irrespective of the phone’s platform. Some functions like a “call-log” ability could also require implementation of the Phone Book Access Profile.

Conclusion

I see that the Sony SBH-52 Bluetooth headset adaptor can work effectively as a Bluetooth headset adaptor when you have a smartphone that is your music player or run a separate Bluetooth-capable music-player device such as a tablet alongside your smartphone. It is also worth its salt if you also value having access to FM radio as another content source while on the go.

As well, Sony is stepping in the right direction by offering Bluetooth headset adaptors like this one that suit the needs of current smartphones and mobile telephony services.

Introduction

I am reviewing the Brother MFC-6720DW A3 colour inkjet multifunction printer which is the latest in Brother’s A3-capable multifunction inkjet printers

The model I am reviewing is the second-tier model in Brother’s new A3 multifunction range with the Brother MFC-J6520DW economy model having only one paper tray and the top-shelf Brother MFC-J6920DW having single-pass duplex scanning and NFC / Wi-Fi Direct mobile connectivity

Prices

Printer

Brother MFC-J6520DW: AUD$279 (Single paper tray)

Brother MFC-J6720DW: AUD$299 (Two paper trays)

Brother MFC-J6920DW: AUD$429 (Two paper trays, single-pass duplex scan, NFC support)

Inks and Toners

It is also worth noting that the Brother LC-133 series ink cartridges, which are standard-capacity cartridges for these printers are compatible with most of Brother’s newly-released consumer and small-business inkjet printer range whether as standard cartridges for some models or high-capacity for others. This may allow you to buy and run different Brother inkjet printers from that range yet be able to buy the same lot of cartridges to replenish them which can be a bonus if your supplier does sell them in quantity at a cost-effective price.

The printer itself

Setup

Brother MFC-J6720DW loaded with documents

Like most of the recent Brother multifunction printers, the trend is to place the network and USB computer-connectivity sockets within the machine and have the machine open up in a clamshell manner to expose these sockets. But Brother also moved the telephony connections used for regular telephony-based faxing to this same area. This can confuse some users who are installing the printer for the first time or moving the printer to a newer location.

Other than that, this printer worked well when it came to setting it up. But Brother still needs to work on the computer software so it doesn’t time out and throw an error message if it can’t find the printer quickly enough or prefer to use the operating system to discover the hardware.

This printer, like the other Brother A3-capable inkjet multifunction printers uses a paper tray that extends to a large size for A3 or collapses for A4 and smaller paper. As well, you load the ink cartridges in a compartment that is at the front of the machine, moving away from the need to lift heavy lids to replace them. Personally, I would like the printer to identify if multiple new cartridges are being replaced at a time which can come in handy if you were doing a few large printing projects and you needed to replace a lot of cartridges.

Walk-up functions – can be started from printer’s control surface

I have done quite a few copying jobs such as some family trees for someone who lives with me and this has yielded high-quality copies although it doesn’t print to the absolute edge and can clip the original at the edge. As well, it “copies to memory” so that you can remove the original document before the copies are printed which can come in handy with multiple-copy copy jobs. Even the ID copy function worked properly with you having to keep the card in the same corner when you turn it over.

Like with most of the recent Brother printers, there could be an option for the printer to keep the same settings rather than timeout to default settings. This would make things easier if you were doing larger copy, scan or fax jobs where you have to spend some time organising the original documents to be worked with. Luckily there is the ability to “preset” common setups as shortcuts which can make this workflow quicker and easier.

For that matter, when you copy, fax or scan from the glass platen rather than the automatic document feeder, you have to position the original lengthways. This confused me initially due to using the Brother MFC-J4710DW which was the first to use landscape printing and required the original in “portrait” mode.

The fax functionality works both with the regular telephone, offering Super G3 with a best case of colour A3 or T.37 store-and-forward with monochrome A4 faxing. If the standard was extended, it could support JPEG colour faxing. The T.37 store-and-forward faxing function is available with a free firmware update from Brother’s Web site.

Like other recent Brother inkjet printers, these printers implement the Web Connect functionality which allows them to be used with a lot of hosted services like Dropbox and Facebook. This comes in to its own with the “download-to-print” functionality for photos or PDFs that these services can offer.

Computer functions

The software that Brother supplies with this printer and most of the other printers gives up too easily when it is searching for the device. It could use the host operating system’s hardware-discovery methods to find the printer.

As for printing, it can turn out most jobs quickly but you would have to set the print driver to the “best quality” if you want to turn out “presentation-grade” colour work.

The A3 functionality comes a long way for larger graphics work including most signage but use the “Booklet” printing with A3 and you turn out a double-sided four-page A4 booklet which could save you money or give you a desktop-publishing bonus.

For operation speed, it turns out most most business documents very quickly but takes a slightly longer time to turn out “best-quality” work. Even turning out the A4 booklet on A3 paper came out properly and quickly.

I have printed some test photos and noticed that this printer does work heavier on the yellow and turn out a darker image. There is still a bit of a redder flesh-tone in people’s faces and this may have an impact with turning out best-quality brochures. For a small-business inkjet printer, these don’t beat the previously-reviewed HP OfficeJet 8600a as a high-quality photo/brochure printer.

Limitations And Points Of Improvement

One area I would like to see improvement take place is with the software where the onus for discovering the printer is placed on Windows rather than the printer’s software.

These Brother printers like the MFC-J6720Dw could implement a straight-through paper path for their automatic document feeders, especially with machines that have the single-pass duplex scanner. This makes them easier to trust with documents that are on fragile paper. Similarly, they could benefit from increased flash memory or a dedicated SDXC card slot for “fax vault” functionality, caching of print queues and similar functionality.

Also a midrange Brother A3 multifunction printer could still implement A4 duplex scanning with A3 one-side scanning as has been achieved with the prior generation of Brother A3 multifunction printers such as tbe Brother MFC-J6910DW that I previously reviewed. This is while a premium model could still support the full-duplex operation for all paper sizes.

Similarly Brother could work on these printers and the rest of their business inkjet printer range to make them answer HP’s OfficeJet Pro 8600 multifunction printer when it comes to printing brochures, flyers and similar marketing collateral. They could achieve this by making the colours more vibrant in most printing modes especially with coated or gloss / matt paper and being able to handle multiple sheets of special-media paper whether in the manual-bypass tray or the paper drawer.

This is due to inkjet printing being material-flexible due to the absence of heat in the printing process. It would be highly relevant with the Brother A3 inkjet printer range because of that paper size appealing to noticeboard or shop-window use or to creation of A4 booklets when the printer is set up to print in “Booklet” mode on A3 paper.

Another way that Brother could “cut in” with their A3 printers woudl be to provide an A3 single-function printer that can answer a lot of the “wide-carriage” A3 inkjet printers offered by Canon and HP or a DCP-series A3 multifunction printer without fax abilities to come in to its own as a cost-effective A3 multifunction when A3 faxing is not on the agenda.

Conclusion and Placement Notes

Any of us who handle large documents regularly would find this latest range of Brother’s A3-capable multifunction printers earning their keep. For most of use, the Brother MFC-J6720DW would come in handy especially if we are also using it as the main printer. The MFC-J6520DW costs $20 cheaper but I would consider it a false economy due to having to switch paper when you want to print on a different paper size. The MFC-J6920DW, which costs significantly more, is for those of us who copy or scan a lot of double-sided documents or want the ability to work with Android-based mobile devices in a standalone manner.

You could easily partner one of these printers with Brother’s HL-4150CDN or HL-4570CDW colour laser printers or the cheaper HL-3150CDN or HL-3170CDW for a high-performance colour desktop-publishing setup for your small business or other organisation. This is where you can use the laser printer with laser-capable media for high print runs while you use these inkjet printers for smaller print runs, large A3 documents, double-sided single-sheet A5 flyers or A4 multi-page booklets on A3 paper and similar work.

UPnP+ links non-IP devices to wide-area networks | EETasia

My Comments

The recent extension of the UPnP Device Architecture specifications, known as UPnP+ is being worked on at the moment by the UPnP Forum. This is to extend the reach of the UPnP Device Architecture specification sets to satisfy certain new realities.

One key reality is to make UPnP work properly with the “Internet Of Everything” concept. This is where devices are able to interlink with each other and share their information in a manner not dissimilar to the concept associated with the Internet.

It will be achieved with native support for IPv6 across IP networks. This takes advantage of the huge number of addresses this standard offers compared to the legacy IPv4 which most of the Internet works on at the moment.

As well, a SensorBridge Device Class will be defined. This caters for the “bridge” device that links sensors and similar devices that work on non-IP networks with IP-based networks. The article talked of the non-IP wireless-sensor networks as being Zigbee, Z-Wave and ANT which take advantage of low-power low-overhead operation suited for those fields. These devices could be represented by “black-box” devices that stand between an Ethernet or Wi-Fi-based home network and the sensors or controllers such as the Honeywell Evohome Mobile Access Kit, but could also be represented as software integrated in either a router that also has a Zigbee or Z-Wave interface or a smartphone, tablet or laptop with Bluetooth 4.0 Smart interface.

There will also be inherent support for cloud-based “hosted” services to be part of the UPnP ecosystem. Of course, I find that the term “cloud” alludes a lot to services hosted by other parties away from the main home network, typically to provide remote access from smartphones, tablets and other computers connected via the Internet. In the context of “Internet Of Everything”, it could extend to service providers like utilities or monitored-alarm companies using this data to participate in the “Smart home” concept.

I would see this come in to its own with home and other networks that are operating along the line of “Internet Of Everything” and this could be supported with newer devices that have newer UPnP+ firmware in place.

“Antivirus is dead” says maker of Norton AntiVirus | PC World

Antivirus Is Dead — Long Live Antivirus | Krebs On Security

My Comments

What did anti-virus software do?

A typical desktop-security program in action

Previously, an anti-virus program was regularly vetting software against a known signature-based list of virus software or, in some cases, Trojan-Horse software. Better programs of this class also implemented “heuristics-based” detection that observed software behaviour for known virus-like characteristics.

The software authors beihind the anti-virus programs were playing cat-and-mouse with the malware authors who are trying to get their rotten software on to our computers. For example, malware authors use “crypting” services to hide their software from the gateway software, typically through the use of obfuscation.

What have the anti-virus software programs evolved to?

These have evolved to robust “desktop security” software suites that perform many different security functions for the computers they are protecting.

Firstly they work with your email client software to vet your incoming email for spam and phishing emails. This will typically work with client-based email setups like Outlook, Apple Mail, Windows Live Mail and others rather than Webmail setups like GMail or Hotmail.

As well, they implement a desktop firewall that  verifies traffic coming to and from the Internet and home network so that malware can’t easily “report to sender” to fulfill its task.

They also implement a wider malware-checking mandate such as catching out rootkits, adware and spyware. Sometimes this is done on a “software reputation” mechanism or observing for particular behaviour traits.

Another function is to implement a “reputation check” for the websites that you visit. This checks whether a Website is a host for questionable software or implementing other questionable practices. This may also be included with a desktop content-filtering function which filters against pornography, hatred and other undesireable content.

They also work as a privacy watchdog by monitoring Websites or social-media services for improper activity that threatens your privacy or that of your child or other vulnerable person.

But, wait, there’s more!

Some of these programs offer extra functionality in the form of a password vault which looks after the passwords for the Websites and other resources you visit.

They may offer a client-server VPN so you can use the Web from other networks like your friends’ and relatives homes or public networks in a secure manner. Similarly, they offer a secure file-storage option, whether on the cloud or on your local machine.

Different levels of functionality available

Most desktop security suites pitched at the home or small-business user tend to be sold with client-focused manageability where you set their parameters to manage that particular client computer. If you have multiple computers, you have to manually replicate that same setup across those computers. As well, they are priced either “per machine” or in a licence-pack that covers up to five or, in some cases, ten machines. You may be lucky to have the software provided as a site-licence that covers equipment owned by a particular household.

Conversely, desktop-security software that is targeted at the big business or at some small businesses is set up for management of multiple machines from one logical point. This includes the ability to deploy the same software across multiple machines yet have the same standards preserved across the multiple machines. They are typically priced in licence-packs that encompass many machines or may also offer a site-licence deal which covers all equipment kept at a particular location or by a particular organisation.

Gigaclear starts installation of its network for Underriver in Kent | ThinkBroadband

From the horse’s mouth

Gigaclear

Press Release

Product Page – Underriver

My Comments

Underriver, a small affluent village just on the southwest of Sevenoaks in Kent has now started working towards a fibre-based Gigabit next-generation broadband service courtesy of Gigaclear. Like other Gigaclear projects and similar projects, it is more about achieving a value-priced real broadband service to the small towns and villages around the UK.

There is a goal to have the service pass 2000 homes and businesses and is to provide a symmetrical Gigabit broadband service which would please a lot of small businesses, professionals working from home or intending to do so and people who have long-distance relationships. This is because the upload speed is as quick as the download speed which would satisfy cloud-computing needs, online storage, Web content creation, VoIP amongst other needs.

Of course, one of these “fibre-to-the-door” deployments is considered a value-added feature for a premises that is being sold or rented out at a later time. This was something I touched on when RightMove were adding this factor to what their customers were searching on when they were seeking out property to buy.

Who knows what other villages and small towns in the “Garden Of England” could duplicate what is happening up in Underriver?

New desktop comptuer at church

As I had mentioned in a previous article, I had moved to a new church congregation and, a few services later, my new pastor had approached me for advice about specifying a new computer for the church. This was because the then-existing computer that was being used to show the song lyrics during worship and to sometimes show video material during a service or similar church event was nearly on its way out.

A risk I often identify with non-profit organisations of any size is where they could end up buying capital equipment that is undersized for their needs or is very likely to fail too frequently. They are also likely to fall for purchasing mistakes where they buy from a vendor who offers the goods for cheap but doesn’t offer good-quality after-sales service and support. In a lot of cases, these organisations are likely to source goods from a “friend of a friend” or “my friend’s boss” where they are not likely to get the best deal and this can place a toll on friendships and relationships.

Identifying the application

I identified that this computer is to be used for AV playout during services and other church activities. One activity that this church also engaged in very regularly is a concert outreach with band members playing the appropriate Christian songs as part of this concert. In these concerts, it would earn its keep with playing out video material or backing tracks for the performances.

These requirements placed an emphasis on multimedia work thus requiring a computer that can handle this kind of work very smoothly. As well, we were moving towards a newer media-playout practice which is to handle file-based media that is provided on a “transfer now, play later” method. This means that the pastor or one of the church elders can receive the media via an Internet path or create the media themselves at home and transfer it to a USB stick to take to church. Then they copy it to the computer’s hard disk for playback and work from the file that is on the hard disk when the time comes to play the material.

The existing system was an orthodox “tower-style” white-box desktop computer that was running Windows XP but was underperforming for today’s requirements due to small RAM and hard-disk space. This is connected to a local screen at the sound desk for cue/monitor purposes as well as a “front-of-house” video projector for the congregation to see the material.

For that matter, a “white-box” computer is a computer, typically a desktop computer, that is built by a value-added reseller or independent computer store using components that the reseller purchases. This can be a custom-built system or a package that is available “off-the-rack” for a known price like this computer.. It was infact the way most small businesses and home users bought their personal desktop computers since the 1990s.

What can benefit this application

For this application, I have identified certain key features that are important. These are increased processor capability and speed along with a dedicated graphics subsystem so as to allow the system to work with the local monitor and the projector in a highly responsive way.

As well, I placed importance on a computer having as much RAM and hard-disk capacity as the church can afford with the minimum being 4Gb RAM and 750Gb to 1 Terabyte hard disk capacity. One of the computer dealer also recommended in to their quote the use of a solid-state drive which can give the computer some speed especially when loading the software such as during startup.

I made sure that the computer came with a legitimately-licensed copy of Windows 7 so that most of those in the AV ministry don’t need to learn new skills if Windows 8.1 was in place. This was assuming that most of the people were operating computers running Windows 7 on their home network or at work.

Obtain competitive quotes

Before any money changed hands, I made sure that the church obtained quotes from a few different vendors. This has an advantage of knowing how much a computer system of this standard was to cost and it also allowed for the pastor to use these quotes as a bargaining tool to get the best value for money.

I made sure that the vendors we had on our shortlist had a local “bricks-and-mortar” storefront because of the issue of service and support. Here, we would be able to talk with the vendor rather than an offshore call centre if the machine did break down. It also allows one of the church elders to put the computer in their car and take it to the store if it needed repairs.

The kind of vendors we went for were national computer-store chains or independent computer stores who were able to build a system to the specifications or have one that was already built. For that matter,smaller independent or local computer vendors are likely to supply a “shop-built” white-box system for better value with local support.

The new system in place

We purchased a small “white-box” system to the specification, installed the necessary software on to it such as EasiSlides and set it up for use in the church. As I was worshipping God through the first Sunday morning service after the computer was installed, I had noticed that there was very little “lag” with the song-lyrics display.

There were still a few issues with the operators getting used to Windows 7 on the new computer after being used to handling Windows XP on the previous computer which I found out after that service and is something that I notice when one is confronted with new equipment.

Conclusion

As I had mentioned in my previous article about purchasing technology for a small business or community organisation, it is important to spend some time “doing your homework” when purchasing the technology. This is to make sure you are buying the equipment that represents the best value for money and can serve you in the long run.

In this case, it involved defining a set of baseline specifications that you won’t go below along with a price range that suits your budget, then seeking different quotes on systems that meet the baseline specifications from a few different vendors for the best price within your range before buying the actual equipment. As well, placing importance on vendors with a local physical shopfront allows for one to be able to obtain prompt service and support if the equipment malfunctions.

Home inkjet printer fabricates circuit boards on photo paper | ComputerWorld

Video

My Comments

There have been a few methods for building electronic-circuit prototypes which involved a “breadboard” of some form and having the components anchored down with either mere friction, with wires inserted in a spring or screwed down with a screw and washer. This was either used to teach electrical and electronics concepts or to “rough out” an electronic-circuit idea and having it work properly before spending time on building a printed circuit board for permanent deployment.

Now Microsoft have come about with a method of making printed-circuit boards using the common inkjet printing method that most printers (including a lot of the ones reviewed here) implement. Here, users could design a circuit using a regular computer and print this out on the photo paper. But the inkjet printer would have to be equipped with a cartridge that holds a special conductive ink and think it is printing something in black and white.

You could then think that you have to solder down the various regular components like diodes, resistors, capacitors and transistors, punching their wires through the paper. But this could prove to be difficult with heat-based soldering and wires attached to the components. Instead, Microsoft and 3M are implementing “stick-on” components that are conductive through the tape as a way to build the circuit that work in a similar way to a SIM card where there is conductive areas on that card.

There would be the requirement to use card-grade paper for improved mechanical reliability as well as the ability to connect regular wire to these circuits whether to connect regular batteries, switches and the like or connect between two circuits. Another issue would be to provide the conductive-ink cartridges for most of the currently-issued inkjet printers so that one can get going with using these printers for turning out the printed circuit boards.

But what I see of this is that equipment used by most computer users could come in to its own with learning electronics or building electronics circuits, especially “short-order” circuits. At the moment, the idea hasn’t been commercialised but the kind of people who could make it sell would include the educational sector or electronics shops of the Maplin, Jaycar or Radio Shack kind.
