The aim of this ‘off-grid’ solar energy project was to build a charger for an eBike so that its battery could be charged (when not in use) from power collected from the sun via a ‘fixed’ off-grid installation, rather than relying on mains energy. This can also be used for other battery charging and small backup supply purposes.
Four main elements were put together to create the solar charging ‘system’:
Solar Panel
This fundamental part performs the key task of converting sunlight into electrical energy. There is a wide range of panel types to choose between. Firstly, sizes include the very small, through 50W, 60W, 80W and up to 100W. Thereafter, systems are typically built from connecting multiple panels together.
Then, there are four main types of solar array:
a) Poly Crystalline – cheaper to manufacture, sensitive to high temperature, less efficient with a shorter lifespan
b) Mono Crystalline – more expensive, more efficient, with a longer lifespanc)
c) Thin-Film Amorphous (A-Si) – flexible, lower cost – easier to produce, shorter lifespan, lower power
d) Concentrated PV Cell (CVP) – very high performance, solar tracking and cooling required, very expensive.
Finally, there is the choice of construction type:
i) Rigid – cheapest and most solid, heavy and longest lasting
ii) Flexible – PET – light-weight and bendy, ideal for vehicles and temporary installations
iii) Flexible – ETFE – longer lasting, marine grade, can be walked on.
For this project, the aim was to use something lightweight that could be easily attached to an existing small building structure by means of the re-enforced ringlets in its corners (not all panels have these, so choosing had to be careful), rather than a permanent roof-top installation, and so the Flexible PET type was indicated.
After some consideration of likely ‘sun-hours’ – estimates tend to indicate an average of 2-3, depending on the season and weather – and also cost, a 50W 12V Mono Crystalline Flexible PET panel was selected. This size could prove to be an under-estimation for the task, but this can be supplemented later as necessary since its possible to join panels in parallel to increase current (or series, to increase voltage). That will require ‘T’ or ‘Y’ joining pieces for the MC-4 solar cable connectors, and potentially in-line fuses to protect separate ‘strings’ of connected panels (on their own they don’t need the fuses since their short-circuit current rating is sufficient).
If a panel becomes partly shaded, its whole output diminishes. Hence the advantage of having separate panels is that they may contribute more energy individually that using one large single panel. Another aspect is that it is likely that the cost of solar panels will reduce over time, and so adding to the system over time makes sense, rather than trying to ‘future proof’ the power requirement.
Charge Controller
The task performed by this element is to ‘condition’ the output of the solar capture, converting an unregulated supply of around 18V (for a single panel) to a more stable 12V, the energy from which can be directly used or stored in the battery. The use of a controller avoids the risk of over-charging of the battery or issues with varying power, and will shut off its output to the loads when the supply is diminished and the battery is discharged. There are many models, which vary in power rating and functionality, some with simple LED displays and others showing a range of information, and may include sense terminals for long cable runs, temperature measurement for adjustment due to the weather and equalisation functionality for spreading charge across multi-battery systems.
The controllers fall into two main types:
a) PWM – Pulse Width Modulation
b) MPPT – Maximum Power Point Tracking
The latter of these is much more efficient, likely to convert more of the captured solar energy into stored power. However, these tend to be at least 3 times more expensive, often much more.
A modestly–priced (reasonably-functioned) PWM unit was selected for this system, with a 20A rating (more than enough for the initial project requirements). The reasoning for this product selection is this: with a small system, should the captured energy be not enough, then purchasing additional panel(s) to increased the wattage is more cost-effective in terms of energy produced, compared with the gain from the more efficient controller. It only becomes worth purchasing the MPPT version when much more energy is being generated (and therefore ’lost’ with a less efficient charge controller).The controller model selected is capable of both 12V and 24V operation, which allows for the increase the voltage rating of the system if desired in the future.
Battery
The traditional choice for this type of storage application is the ‘Lead-Acid Cell’, though it needs to be of a Deep-Cycle ‘Leisure’ variety, which is intended to be frequently discharged and recharged, rather than the ‘starting’ classification which is used in a vehicle for short-bursts of energy to get a motor running, after which its mainly in stand-by and therefore expected to be 100% charged most of the time.
Apart from this distinction, there are two main types of product:
a) ‘Flooded’ Wet-Cell or Valve Regulated Lead-Acid (VRLA)
b) Absorbed Glass Mat (AGM) or Gelled Electrolyte (Gel)
Of these, the Wet-Cell traditionally required periodic ‘maintenance’, topping up with fluid, though VRLA sealed versions are now available, and tend to ‘vent’ gas and can’t be tipped over due to the fluid inside. The AGM and Gel types however are available maintenance-free, don’t ‘vent’ gases and don’t have fluid that can spill out.
The AGM-type was selected for this project as, whilst being a bit more expensive, offered the convenience of a product shouldn’t require special attention; these are less sensitive to over-charging and can stand for 30 days totally discharged without harm.
There are a number of measurements of the capacity and capability of batteries:
A capacity of 110AmH was chosen for this project. Whilst ‘the more the merrier’ in terms of storage is certainly the case, this capacity should be sufficient for the basic storage needs. It is advisable however to allow for discharge of only 50% of the stated rating, whilst also bearing in mind the possibility of a few days without sun.
It is possible to add batteries in Parallel to create more storage, or in Series to increase the voltage of the system. For a modest system set-up, 12V is sufficient and convenient for the purpose. Adding another battery to double the system voltage to 24V would have a side-benefit of requiring lower gauge of wiring.
Inverter
In order to convert the 12V DC power generated from the Solar Panel and stored in the battery, to the 240V AC required by the Load, the Li-Ion battery charger adapter, an inverter is needed. This wouldn’t be the case if a suitable 12V charger-adapter could be sourced, which would avoid the inefficient ‘double-conversion’ of 12V DC into 240V AC and back into 42V DC again. The inverter does however provide the flexibility for powering other equipment requiring an AC ‘mains’ supply and therefore is ideal for a range of charging and backup tasks.
Apart from the selecting the correct voltage, which is normally either 12V or 24V (12V required to fit with this system set-up), there are two main choices:
a) Modified Sine-Wave
b) Pure Sine-Wave
The first type is the low-cost product, and available in a wide range of power-ratings, so if high-power is required then that tends to be the preferred choice. The draw-back is that it is less-efficient, creating a ‘blocky’ AC waveform which can upset sensitive equipment. The second type produces a smooth sinusoidal AC waveform equivalent to the standard AC ‘mains’ supply, and therefore is suitable for all equipment types, though at higher cost and usually lower-power rating.
Given the performance uncertainty and potential for harm to some equipment that the MSW product might bring, and the modest power needed, it seemed sensible to select the PSW variant. A 300W product was chosen, partly limited by cost, but also since it is recommended to ‘match’ the power rating to the consumption requirements; in practice the inverter size should be around 3-7 times the power needed by the load appliance. A much higher-than needed inverter is ultimately less efficient for smaller loads, consuming more power than necessary.
Additional parts required were cabling and mounting accessories, plus some optional ‘add-ons’ in the form of other battery chargers and lights to make full use of the generated power:
System accessories
The resultant assembly captures energy from the sun via the solar panel, ‘conditioned’ by the controller (to avoid over-charging or issues with varying power) and stored in the battery. Naturally, this can take place throughout the day when the sun shines, without the need for a load to be present. Then when required, the load can be supplied from the stored energy.
The inverter is utilised to supply a replacement AC feed to the specialised Li-ion charger required for the load battery, which can therefore be used as an ‘off-grid’ power source for other uses in place of a regular ‘mains’ supply.
Charging additional Li-ion or Ni-Cad batteries for other equipment can be also be facilitated using the 12V output to supply an appropriate battery charger, and as well as powering 12V LED lights for illumination of the work space.
Hopefully this project is of interest and of use to anyone contemplating establishing a solar energy system, with the aim of harvesting energy from the sun, a ‘free’ resource available to us all!

The ‘Personal Computer’ (PC) launched by IBM in 1981 was a breakthrough that revolutionised the workplace, though the early ones were quite limited especially in terms of how to use them and what they displayed. Not only did they have no ‘touch screens’ for ‘swiping’ and ‘apps’ as we know them now, but there was no ‘graphical user interface’ either. Rather than a ‘desktop’ with icons and a mouse pointer, there was just a black screen with text and a flashing cursor.
This was Microsoft DOS (Disk Operating System), which seemed to be the ‘proper’ way to use computers for at least a decade.
Indeed, some PC users were initially ‘suspicious’ of icons and windows which had appeared on the Apple Mac as well as other alternatives in use like GEM on the Atari ST.
People had become so used to typing commands, and knew all the ‘switches’ and other modifiers e.g. DIR /W to display a list of the files across the screen rather than in a column. And ‘WP’ was all you needed to get ‘Word Perfect’ to launch – the then favoured Word Processor, which gave rise to some still familiar short-cuts like ‘Control-C’ to copy.
Windows 3.1 showed PC users something different from around 1992, when 386 and 486 PCs powerful enough to run it well became available.
It even came with a tutorial to show users how to use a mouse!
No-one enjoyed having to install it using 7 floppy disks though.
And at first it seemed somewhat unnecessary to run existing applications.
Indeed, there was a bit of an ‘outcry’ that Windows 95 and later variants didn’t first boot into DOS!
But then it was realised there were some key benefits. Now you could delete a whole directory in one go without having to clear out each ‘level’ – not always the safest feature! Email really became more useable when you didn’t have to log in specifically to check to see if you had messages; now it could be running all the time in its own window.
With each variant of ‘Windows’ came more sophistication, and suddenly a whole world of connected information could be accessed with Netscape and then Internet Explorer, which then meant Windows really became a ‘must have’.
Certain difficulties were experienced getting old and new applications to behave themselves in the Windows environment; stability and also backwards compatibility started to become issues. Users now had to deal with ‘blue screen’ crashes of Windows, and then a variety of increasing security threats and viruses requiring ever-more enhanced anti-malware protection applications and mandatory backups.
Although the majority of modern offices, educational establishments and homes now use the latest PC hardware as well as phone and tablet computing devices running the newest generation of operating software and applications, some industrial workplaces have professional implementations of systems that still make use of early computing platforms (ranging from desktop PCs to OSS servers), where the basic requirements are unchanged, and particularly in stand-alone use where security threats aren’t an issue. And some people still have old PC games to play!
It can however be quite a task to restore the operation of legacy systems, particularly if backups are missing or incomplete.
Associated issues include obtaining the appropriate hardware replacement parts such as disks (modern versions can be too high capacity to work well with old systems) requiring the right settings of cylinders, heads and sectors, and preparation using FDISK and FORMAT commands.
Software ‘patching’ of configurations may be needed, hunting out correct versions of driver files and specifying the right parameters. Creating a floppy disk with ‘boot’ files can also be a helpful tool!
There’s still a way today to run legacy software even without the old PC hardware, and that’s via the ‘joy’ of emulation and virtualisation. Even using an Apple Mac or Linux computer, it’s possible to run various flavours of Windows legacy software.
Particularly useful applications to enable this include:
DOSBox – a handy emulator tool which enables the running of old DOS based applications in an application window. Relatively straight-forward to setup, with the ability to ‘mount’ folders so that files can be imported.
VirtualBox – a fully featured virtualisation tool that allows the creation of ‘virtual machines’ into which can be installed a full operating system, such as Windows 3.1, Windows 95 or Windows XP. The tool also emulates CD and Floppy drives for loading disk images and running legacy applications.
Takes a bit of work to set up, preparing a virtual ‘hard disk’, and then installing the operating system. There’s a ‘work-around’ needed to take account of modern processors being ‘too fast’ for the old operating software! Also, to set the display to the necessary resolution and get sound working, special video and audio drivers may need to be installed.
Or you could try the Windows 95 ‘computer as an’ App created by Felix Rieseberg, which can be downloaded and installed on macOS, Windows and Linux!
@YellowsBestLtd we can assist with support services for both legacy and new software and hardware solutions, so please get in touch if you have any requirements you’d like to discuss; we look forward to hearing from you.
Remember way back in the late 90’s and early 2000s, when Nokia ruled the mobile phone market, they launched the Communicator series. Essentially it was the coming together of a mobile phone and a PDA, joined with a hinge that ‘opened up’ to reveal a full QWERTY keyboard and display screen. Always somewhat big and bulky, it initially was way ahead of anything else, offering phone, text, email and even fax communication.
The E90 was the last and most feature-packed variant, produced in 2008. More compact and powerful, it featured colour screens inside and out, video and photo cameras with flash, 3G telephony, Bluetooth and WiFi connectivity, together with internet browsing, GPS maps, photos, video and music players, radio, clock, calendar, contacts and a file manager, plus games and the ability to install apps like quick office for document creation and spreadsheeting. In short, it had everything we’ve come to expect in a ‘smartphone’, lacking one key ingredient – a ‘touch’ screen.
10 years on, it’s a testament to Nokia’s impressive build quality that it looks almost as good as new and still works as well as it did, though of course without the ability to pinch, zoom and swipe, and no ‘app store’. The photo and video quality now looks very basic, as do the limited number of games and apps; but it is possible to load it up with an up-to-date Opera web-browser and Google maps. The music player still works well, using a headset or in speaker mode, as does email and texts – and naturally it can still make telephone calls!
The Nokia phone business itself didn’t fair so well, being eclipsed by the competition and then sold off, as recently well documented in “The rise and Fall of Nokia” (shown previously on BBC4, now on youtube) by Arto Koskinen. However, more recently Nokia phones have made a bit of a comeback, relaunched by HMD Global. Though probably no hope of a new Communicator model?!
If you can remember the 20th Century and the dawn of the mobile phone, then the Nokia 5110 maybe familiar. Introduced in 1998, during the period of Nokia’s seemingly unstoppable rise, and helped them become the world’s number one mobile phone producer, which they remained for the next 14 years.
This was the breakthrough when phones ceased to be ‘bricks’ (though still including an external antenna) and became mass-market devices that everyone could consider carrying, even just as an ‘emergency’ phone. Text messaging was included, though many people at the time couldn’t see what the point of that was: “its easier to just ring someone, isn’t it?” How times have changed! Plus it had a clock, calculator, and a choice of ring tones including the now famous ‘Nokia tune’. And Nokia introduced the world to ‘snake’, heralding in the era of mobile gaming. No app store yet, and ‘touch screens’ and even colour displays were still to come. But you could now choose the colour of the product; they didn’t have to be just black anymore!
The phones themselves were of the solid long-lasting construction that characterised the products of that time from the Finnish manufacturer, perhaps due to the harsh winter environment of home they were built to survive, which is why 20 years later, it still works! Looking back, the surprising thing is that despite its rugged nature, a case was often used, and given the (now, seemingly) impressive talk and standby time, it was quite usual to have a spare battery too. Perhaps that was because they were still seen as an expensive luxury, and given that ‘normal’ desk phones didn’t run out of power, ‘early adopters’ wanted to make sure they could always make use of their investment.
Much has since changed in the world of mobiles, such that they’re not even used much as just ‘phones’, and Nokia’s phone business itself came and went, though now being revived by HMD Global. On the cusp of the launch of a new ‘flagship’ model, the Nokia 6.1 plus, it’s also interesting to see the ‘re-introduction’ of some ‘classic’ phones, the 8110 and 3310, harking back to those early beginnings.

An annoying issue (for UK users) is of the date format defaulting to US (MM:DD:YY) rather than UK (DD:MM:YY). This occurs when transferring to a new Apple Mac computer with a previously correctly working installation of Microsoft Excel:mac 2008 (from an older computer, but running the same version of OS X). In theory, there should be no change, but hidden somewhere in the setup of the new computer lurks something preventing use of the UK date format.
The problem shows itself when, in a new Excel worksheet, a date is entered, e.g. using the formula =TODAY() returns something like 11/22/16 (for 22nd November 2016) instead of 22/11/16. Worse, if an existing workbook is opened, which had previously correctly UK-formatted dates, they are all changed to the US-variation. A particular ongoing problem is then generated when new dates are added to the sheet, as entering 1/12/16 is then taken as 12th January not 1st December 2016.
It turns out that the issue manifests itself in any User account set up on the Mac computer EXCEPT the ‘Guest’ account, which mysteriously sets the date to the UK-format. Hence this provides the clue to solving the problem. After some searching and trial-and-error, I have identified that the issue relates to the absence of a key file: com.apple.HIToolbox.plist, which for some reason is not created when setting up a new User account (and may not be copied across if importing from another computer). Luckily this file is created when opening the Guest account, which can then be copied across to all required User accounts.
Here is a detailed summary of the procedure I eventually used to fix this date format issue:
Panasonic DMR-EZ25 DVD Recorder
The DMR-EZ25 is a reliable and highly-specificationed DVD Recorder, and like several models made by Panasonic somewhat special by it’s capability of being able to use DVD-RAM disks (as well as the more common DVD-R and DVD-RW) for maximum flexibility of recording and playback.
This model does however sometimes fail, displaying various fault codes, preventing use but at least giving an indication of the likely problem(s). Fortunately, it is then relatively straight-forward to disassemble using just a screwdriver, and thereby replace (or repair) the relevant component modules.
Here are the full disassembly and reassembly procedures I followed to restore my unit, which had been displaying the fault code ‘U81’, to full working order by replacing the main PCB board.
Disassembly procedure
1. Remove top panel, removing 3 screws (normal, non-washer type) at rear and two on side (big).
2. Remove front panel, which pulls off once lugs are pushed back, being careful not to break lugs.
3. Remove HDMI board, removing one screw (normal type) and then easing it out of the black connector on the main board and the ribbon cable out of its socket on the digital board.
4. Remove the SD card board, removing two washer-type screws and the ribbon cable out of its socket on the digital board.
5. Remove the rear panel, removing 6 normal screws and 2 smaller machine screws by the SCART sockets, then unplugging the FAN connector cable from the PSU board (alternatively, you can leave this connector in place and lift the panel away with the PCB board).
6. Remove the PSU board, removing the three washer-type screws and easing the black power rail connector from its socket on the main board.
7. There’s no hard disk in the EZ25 model, other products have an extra step.
8. Release the digital board from its mounting frame, there are three washer-type screws (and an empty socket where a fourth one is not present), easing it out of its black connector socket on the main board hidden underneath and then fold it over onto the disk unit keeping the ribbon cables attached
9. Remove the DV input board, removing one normal-type screw.
10. Remove the digital board metal support frame, removing four washer-type screws.
11. Remove the power button pcb, removing the washer-type screw and sliding it from the lugs being careful not to pull the ribbon cable.
12. Remove the main board, removing the four washer-type screws and the ‘hidden’ normal type screw on the front by the AV sockets.
13. The remaining disk drive unit removes from the base panel, removing two washer-type screws and lifting out with the digital board (which can be disconnected if necessary by careful detaching of the ribbon cables).
Re-assembly procedure
1. Insert main board into chassis (and also the disk drive if removed, with digital board, with two washer-type screws). There is a lug to align into a hole at the front left edge, one at the front right side and a bent lug at the rear to slide under. A ‘hidden’ (non-washer type) screw is located at the front by the phono sockets, and four more screws secure the main PCB to the chassis, all are ‘washer-type’.
2. One screw secures the power button PCB, aligned with two lugs.
3. Five screws secure the metal frame for the digital support board.
4. One (non-washer) type screw holds the DV input board which needs aligning with the holes in the main board at the front next to the phono sockets.
5. The digital board flips over with its ribbon cables in place, mounts onto the frame, tucking under the lugs, slotting the DV input board into place and pressing down onto the main (black) connector underneath.
6. Three screws secure the digital board in place (a potential fourth, in the far right corner (away from the front panel) is not present.
7. No hard disk is present in the DMR-EZ25 model (different models have this extra step).
8. The power PCB is placed into position, and it’s power rail connector presses together. Three screws secure it in place.
9. The rear panel clips securely in place. Six screws secure it, all ‘non-washer’ style and two ‘machine-type’ screws locate between the SCART sockets . The connector for the fan presses in place.
10. The SD board mounts at the front onto the digital board, with a lug and two ‘washer-style’ screws. It’s ribbon cable presses in place.
11. The HDMI board slots into place onto its black connector and its ribbon cable slots into place on the digital board. A screw on the rear panel secures it in place.
12. The front panel clips in place.
13. The top panel pushes on, slides in place and is secured by three non-washer type screws on the rear and two large flat screws on the sides.
