Mobile device will not connect to Zorin OS with Zorin Connect

Zorin OS is a highly polished Ubuntu-based Linux distribution providing an excellent alternative to Windows and MacOS. It is a an operating system that is gaining popularity (distrowatch) for many reasons. One of those reasons is the ability to integrate your Android mobile device with Zorin OS by utilizing the built-in Zorin Connect.

Once your mobile device is paired with Zorin Connect via your local area network, the technology releases a number of features and benefits including:

  • The ability to share files and web links between devices
  • Send and receive SMS text messages from and to the desktop
  • View your mobile device’s notifications on your desktop, including incoming calls
  • Control slideshows and multimedia on your desktop from your mobile device
  • Issue commands on your mobile device to execute on Zorin

And there’s plenty more.

Backup Minecraft Worlds from an iPad or iPhone with a PC

How to backup Minecraft Worlds created on an Apple iOS device, to a PC and then restore them.

This article describes how to make a copy of your Minecraft Worlds created on Apple iOS mobile devices such as the ipad or iPhone, to a PC without using iTunes.

This is particularly useful if the Minecraft app becomes corrupt and you need to re-install it from the App Store. Before an app can be reinstalled on an iOS product, it has to be deleted first. The deletion process removes all associated data with that app, in this case your Minecraft Worlds. And, you don’t want to lose them, do you?

Attempting to make backups with iTunes is well documented on the internet but  can lead to frustrating errors such as:

"games" could not be copied because an error occurred. A duplicate file name was specified.

The following method works flawlessly and will prevent loss of your Minecraft Worlds if you ever find it necessary to re-install Minecraft on your iPad or iPhone.  There’s also no need to install iTunes on your PC.

What You Will Need

  • A PC running Windows. This computer will require a USB port.
  • The USB to iOS mobile device charging lead.
  • Syncios installed on your computer.

Syncios is a free, powerful and comprehensive tool to manage and transfer  files between an iOS device and a PC/MAC.

Steps to Backup and Restore Your Minecraft Worlds with a PC in the Event of Minecraft Re-Installation on an iOS Device

  1. Download and install the free version of Syncios to your computer.
  2. Launch Syncios on your computer.
  3. Connect your mobile iOS device to your computer with the charging lead and the computer’s USB port.
  4. If this is the first time you have connected your device to your computer, your mobile iOS device will ask to trust the connection. Trust the computer.
  5. Syncios will take a few moments to detect your iOS mobile device. And, when it does, it will display an overview of the detected device.
  6. Dismiss the warning: Turn off iTunes and do not operate your mobile device directly when running Syncios.
  7. Select Apps from the left-side menu.
Syncios | My Devices
  1. Scroll through your installed apps until you find Minecraft.
  2. Under the

    Actions column, click the ‘eye’ on the right-hand side of the trash can to open Minecraft’s app documents.

Syncios | Open the Minecraft App Documents Folder

  1. Double-click the games folder.
Syncios | Double-click the games Folder
  1. Double-click the com.majong folder.
Syncios | Double-click com.mojang folder
  1. Inside this folder is a folder called minecraftWorlds, which contains your saved game data. The contents of this folder can be copied to your computer in two ways: Either tick the box next to the folder name and then click Export OR drag and drop the folder from Syncios to an open folder on your desktop.
Syncios | Export minecraftWorlds to PC
  1. Check the content of your copied folder by exploring within on your PC. The Minecraft Worlds are each saved in separate folders named with unique random characters and ending with =
Minecraft Worlds contained in a Separate Folder
  1. Disconnect your iOS mobile device from the computer.
  2. Delete the Minecraft app from your mobile iOS device then re-install it from the Apple App Store (you won’t have to pay again).
  3. Launch Minecraft on your mobile iOS device and create a new world. Then, exit the Minecraft app.
  4. Re-connect your mobile iOS device to your computer and wait for Syncios to detect your device.
  5. in Syncios, navigate to AppsMinecraftDocuments/com.mojang/games/minecraftWorlds in the same manner as steps 7 to 11.

  1. Close Syncios and disconnect your iOS mobile device from your computer.
  2. Launch Minecraft and enjoy!
Honsel Loft 44441 Floor Lamp

Honsel Loft Review

A Review of the Honsel Leuchten Loft Collection

For the sake of clarity, this is a review of the Honsel Loft collection of lamps with the cappuccino fabric shade, purchased from Amazon with hard-earned cash.

Honsel Leuchten Loft Collection

This German-made Honsel Leuchten Loft collection consists of:-

The Honsel Loft collection can also be purchased with a white shade:-

Honsel Loft Cappucino Shade

The colour of the cappuccino fabric shade is consistent across all the Honsel Loft range. A point you may need to be assured of if you intend to purchase more than one lamp from this collection.

The cappuccino fabric shade is a composite of a rich brown woven textile on a white plastic light defuser. It looks good whether illuminated or not and will compliment any neutral colours in your room.

The two ends of the shade material are stitched together to form the shade’s circumference, resulting in a visible vertical seam on one side of the shade. The join is quite obvious when the lamp is lit and this might be a factor for consideration. However most lamps, such as the Table and Floor Lamps, are likely to be situated near a wall with the seam orientated out of sight. Potentially then, the seam might only be a problem in you intend to view this lamp from 360°. I own the semi-flush ceiling lamp which can be viewed from any angle and the seam does not bother me. In my opinion, it adds to the appeal of the shade.

Honsel Leuchten Loft 20462 semi-flush Ceiling Lamp

Honsel Leuchten Loft semi-flush Ceiling Lamp

The shade defuses and absorbs light to a pleasant level (at a guess I’d say approximately 20% of the bulb output) yet allowing full light to be thrown both up and down from the lamp shades. The light cast in the locale is pleasing, emphasising the nickel finish of the base and stand of the lamps. The strength of down-light is more than ample for nearby reading or writing tasks. The whole effect is comforting in the evening.

Honsel Loft 44441 Floor Lamp

Honsel Loft Floor Lamp | Philips Hue Bulb Producing Daylight 100%

Each lamp from the Honsel Loft collection is a well made, quality product and looks more expensive that it is to buy.

What to expect when you order from Amazon

Typically, Honsel Loft lamps are shipped from Germany, so even if you’re an Amazon Prime member, don’t expect next day delivery. However, as a Prime member, delivery will be expedited and the item will be rushed to you as fast as practically possible. All my items, which I ordered separately, arrived within a couple of days.

Detailed below is my experience of receiving both the Honsel Loft Table Lamp and Honsel Loft Floor Lamp.

Receipt of the Honsel Loft Table and Floor Lamps

These Honsel Lamps arrive extremely well packaged and require minimal assembly. The electric cable is already threaded through the base to the lamp holder. All that is required is to screw the stand into the weighted base, unwrap the well-protected fabric shade and fasten it to the lamp. Then screw in a bulb of your choice into the E27 cap. I opted for a Philips hue ambient and colour bulb in mine and they look gorgeous when illuminated in any colour and at any brightness!

Honsel Loft 44441 Floor Lamp

Honsel Loft Floor Lamp | Philips Hue Bulb Producing Blue 100%

Philips Hue White and Colour Ambience Personal Wireless Lighting 2 x 9.5 W E27 Edison Screw LED Twin Pack Light Bulbs

Lamp assembly is easy and just takes a few moments, although you may find that unwrapping the well-protected shade itself will take the longest time. The support for the floor lamp is made of two sections, which screw together seamlessly in a matter of seconds. This enables the tall floor lamp to arrive in a relatively small package.

I really like the choice of the semi-transparent electric cable and the integrated rocker on/off switch. The transparency allows both the cable and switch to blend in with its surroundings somewhat and are difficult to see from a distance if they happen to be on show. A neat feature in my opinion, and much better than having a high contrast black or white cable attached to the lamp. The rocker switch makes lamp operation simple and easy.

Honsel Table Lamp

Honsel Loft Table Lamp | Transparent Power Cable and Rocker Switch

The cable is two core and terminates with a European 2-pin plug. If you don’t have any spare, you may need to factor in ordering some EU adapter plugs at the same time. Amazon class these as add-on items. They’re not expensive, but ordering them separately will incur delivery charges. Check prices.

UK Travel Converter Plug – Euro 2 Pin to UK 3 Pin Adapter

It is also worth noting at this point that this lamp is not earthed but is perfectly safe to use. Due to the lamp’s design and the careful consideration of materials used in its construction, the exposed parts of the lamp are either non conductive or insulated. For example, the base and stand are made from a tough plastic and coated with the ‘nickel’ silver finish in order for the lamp to appear to be metallic.

The lamp bases are weighted sufficiently to prevent the product from being knocked over from general bumps.

Honsel Leuchten Loft 20462 semi-flush Ceiling Lamp

The Honsel Leuchten Loft semi-flush ceiling lamp is a beautiful modern shade that is easy to install. A quality, white-enameled lamp screws into the ceiling, to which the lamp shade is attached. The shade is completed with a white diffuser, resulting is a very pleasing finish indeed.

Instructions on how to insert the diffuser into the shade are provided. This is a tricky operation that can be accomplished easier with help from another person.

The lamp has two E27 caps and again, looks great when fitted with the Philips Hue colour and ambient bulbs.

Philips Hue White Ambience Twin pack A19 E27 60W Equivalent Dimmable LED Smart Bulbs

Advertised as semi-flush, the lamp shade of the Honsel Leuchten Loft 20462 sits approximately 25mm (1″) away from the ceiling. This creates a beautiful aurora between shade and ceiling when the lamp is illuminated. The lamp holder cannot be seen from ground level.

Block Spam SMS With No Number

‘Block’ Spam SMS With No Number

Spam text messages without number | How to block messages without number | How to block sms without number | Spam text with no number | How to block sms without number in Samsung | sms no number | How to block spam sms with a name not number

This article describes how to ‘block’ spam SMS text messages that have a name instead of a number and is specific to smartphones that use the Android operating system.

Without installing any third-party apps, this guide shows the steps taken on a Samsung S8 smartphone to ‘block’ spam SMS messages that have no number, by constructing a filter to identify and capture them.

Samsung S8

It replaces an older article written for the Samsung S3 mobile phone: How To Block Text Message SMS Spam on Samsung Galaxy Phones (Android)


Smartphones that run on an Android operating system are capable of diverting spam SMS text messages to a spam folder, even if the telephone number is absent from the message or the telephone number has been replaced with a name. Although these messages are still received by your handset, the method of identifying and diverting spam in this way creates the illusion that the nuisance message has indeed been blocked.

To ‘block’ spam SMS text messages that have a name instead of a number, follow these simple steps:-

STEP 1: Open the Samsung Messages app.

Samsung S8 Messages App

STEP 2: Identify the spam SMS text message and tap it.

Identify Spam SMS

 

STEP 3: Take note of the keywords or phrases that are in every message received.

SPAM SMS Message – Note the Keywords

In this example, I use the name of the sender, LloydsBank and the word ENTRIES.

STEP 4: Go back to your list of messages by pressing the back arrow, top left.

STEP 5: Open message options by tapping the three dots at the top right of the screen

Message Options

STEP 6: From the options that appear, tap Settings.

STEP 7: Tap Block messages

Block messages

STEP 8: Tap Block phrases – Manage the phrases that will cause incoming messages to be blocked.

Block phrases

STEP 9: Enter the keywords or phrases noted in step 3.

Block keywords and phrases

Type a keyword or phrase then tap the plus (+) symbol to add it to the list. Remove a keyword or phrase by tapping the minus (-) symbol associated with that text.

As soon as a keyword or phrase is entered, then any new SMS message that contains that text will be diverted to the Blocked messages folder and effectively ‘blocked’.

It is important to note that:-

  • phrase matching is not case sensitive and all text entries are stored in lower case.
  • if a genuine SMS text message contains one of your chosen keywords or phrases, then that message will be ‘blocked’ too. It is therefore important to choose your keywords and phrases carefully.

STEP 10: You’re done!

Return to the Messages main list by tapping the back arrows on each of the option screens.

How to check Blocked messages

Once you have your keywords and phrases in place, it is worth checking your spam SMS folder occasionally to check its effectiveness.

The Blocked messages list can be accessed from the Messages main conversation screen by tapping the three dots, top right, and selecting:-

REVIEW: RAVPower RP-PB057 Battery and Charger Set for Nikon Cameras

Product Description

RAVPower RP-PB057 Rechargeable Battery and Charger Kit

RAVPower RP-PB057 Rechargeable Battery and Charger Kit

The RAVPower EN-EL15 2100mAh rechargeable camera battery and charger set is an affordable aftermarket camera accessory that offers a tonne of features and benefits over the Nikon MH-25 battery charger.

This RAVPower battery and charger set aims to provide a complete backup power solution for your camera. With an extra two replacement batteries and a dual charger to keep empty batteries charging on the go, you will always be prepared for those unexpected moments when your camera battery runs out of juice.

With this kit, you will have the potential to triple your camera’s run time with the two extra batteries alone. And, with the charger being able to connect to any micro-USB power source,  this makes charging extremely versatile, as batteries could even be charged in remote locations with a portable battery, such as the RAVPower 26800mAh Power Bank.


RAVPower 26800mAh Power Bank Portable Charger 3-Port 5.5A iSmart Output External Battery Pack for Mobile Phones, Tablets and More RAVPower 26800mAh Power Bank Portable Charger 3-Port 5.5A iSmart Output External Battery Pack for Mobile Phones, Tablets and More

Good to know: This power bank is capable of recharging one EN-EL15 2100mAh battery approximately 12 times from a full charge.


Package Contents:

  • 2 x Replacement Batteries for Nikon EN-EL15 2100mAh
  • 1 x DC Dual Battery Charger
  • 1 x micro-USB Cable
  • Warranty Card

Batteries:

RAVPower claim that their replacement batteries (RP-PB057 Savior Series) are made to the exact specifications of the Nikon EN-EL15 battery but with a slightly larger capacity of 2100mAh/14.7W compared with the 1900mAh/14W of the Nikon EN-EL15. This equates to a 10.5% increase in battery capacity over the original.

RAVPower RP-PB057 SAVIOR Series Nikon EN-EL15 Battery V Nikon Original

RAVPower RP-PB057 SAVIOR Series Nikon EN-El15 Battery Pack V Nikon EN-EL15 Battery

In my own tests, where I used these batteries continuously for 3 days in a Nikon D7200, I found no discernible difference in battery performance when compared with the original Nikon EN-EL15 battery. The RAVPower batteries charged just as quickly as the Nikon original; shooting duration and number of shots obtained were also on par with the Nikon.

RAVPower RP-PB057 batteries will charge inside camera if your camera model supports this feature. However, note that some models, like the Nikon D7200 do not support inside camera charging.

Charger:

The RAVPower battery charger is light weight, but well made from a relatively strong, fire resistant plastic. It features two battery compartments and a pair of LEDs labelled CH1 and CH2.

The LEDs indicate charging status and glow red when a battery is charging. The LEDs glow green when a battery if fully charged or when a battery bay is empty.

The RAVPower charger is capable of charging the original Nikon EN-EL15 battery alongside a RAVPower equivalent.

The RAVPower battery charger needs to be connected to a power source via the USB to micro USB cable provided.

RAVPower recommend that you connect to a charger capable of delivering at least 2.1 Amps to maximise charging efficiency. However, connecting to any USB power source will still charge the batteries. It will just take longer.

Review: ZD V Full Vibration Feedback 2.4G Wireless Controller Gamepad Joystick For PC, Playstation 3, Android and Steam

ZD V Full Vibration Feedback 2.4GHz Wireless Controller Gamepad Joystick for PC (Windows XP/7/8/8.1/10), the PlayStation 3, Android devices and Steam.

For the sake of clarity, this is a review of the ZD V Full Vibration Feedback 2.4GHz Wireless Controller Gamepad Joystick for PC (Windows XP/7/8/8.1/10), the PlayStation 3, Android devices and Steam. It was purchased with hard-earned cash, so this review reflects that in terms of value for money.

The controller was purchased to compliment a RetroPie set-up and for occasional use with games on Steam.


The ZD V Full Vibration Feedback 2.4GHz Wireless Controller Gamepad Joystick is designed and manufactured by Dongguan Zhi Dong Electronic Technology Co. Ltd. in China. They are Amazon Marketplace Sellers and offer an incredible piece of gaming hardware for the money. A wired version of this model is also available with the same features as the wireless one. Both controllers are Plug and Play and PC fully compatible. They both contain a 360 core, which means that they are recognized as XBOX 360 controllers.

Features & Operation

The ZD V Full Vibration Feedback 2.4GHz Wireless Controller Gamepad Joystick is equipped with the following buttons, triggers and joysticks:

Controls: ZD V Full Vibration Feedback Wireless Controller Gamepad Joystick

Controls: ZD V Full Vibration Feedback Wireless Controller Gamepad Joystick

Both the LEFT STICK and RIGHT STICK are stick buttons and can therefore be clicked: LSB and RSB.

The trigger buttons [LT & RT] feel like single click buttons. They are, in fact, pressure sensitive buttons that provide linear graduation through pressure sensing. This means that the harder you press them, the greater the input value sent to your game. This feature means that the gamepad can be used in conjunction with racing games that require progressive braking and acceleration, or shooting games, where a one click shot is all that is needed.

Shoulder and Trigger Buttons - ZD V Full Vibration Feedback Wireless Controller Gamepad Joystick

Shoulder and Trigger Buttons – ZD V Full Vibration Feedback Wireless Controller Gamepad Joystick

Integral Rechargeable Battery

A micro USB port, located in between the shoulder and trigger buttons, is used to charge the on-board lithium battery and connect the controller to an Android device. The battery can be charged by connecting the device to a suitable 5 volt power supply via the supplied USB cable. A computer USB port or mobile phone charger will suffice. A charging unit is not supplied with the product, presumably to keep the cost of the units low.

The ZD V Full Vibration Feedback 2.4 GHz Wireless Controller GamePad Joystick is shipped with the battery partially charged. The temptation is to start using the game controller straight out of the box without fully charging the battery. I encountered numerous problems when I did just this, problems that disappeared when the device was fully charged later.

Since the lithium battery is integral with the controller, this means that it cannot be changed easily.

Important points for consideration are these:-

  • If the battery runs flat during a gaming session, the battery cannot be replaced. Instead, you would have to connect the controller to a charger, which means that you are now tethered to your charger until the battery has sufficient juice for you to remove it.
  • Lithium batteries have a finite lifespan due to the repetitive cycle of power depletion and recharging. When the battery begins to fail to hold charge for a decent period of time, then changing it may be difficult and expensive.

After a full charge, the ZD V Full Vibration Feedback 2.4 GHz Wireless Controller GamePad Joystick battery power lasts for a considerable amount of time. On a full charge, the battery lasts between 8 and 15 hours of continuous game play. These figures are in line with the published specifications.

Connection

Connection to gaming hardware if relatively simple. Just insert the wireless USB dongle into a USB port of your gaming equipment and select the operation mode of the gamepad with the HOME button.

On a PC platform, the gamepad is Plug and Play – except for Windows XP. For use on Windows XP, you will need to download and install the 360 controller driver from Microsoft’s official website before plugging in the USB dongle.

PS3 and Android platforms are Plug & Play.

How to Turn the ZD V Full Vibration Feedback 2.4GHz Wireless Controller Gamepad Joystick ON and OFF

  • TURN ON: Press the HOME button.
  • TURN OFF: Long press the BACK & B buttons together. Alternatively, the gamepad will automatically turn off after a reasonable time of inactivity.

Mode and Indicator Light Status

Press the HOME button to cycle through the input modes compatible with your device. The  colour of  the indicator light specifies what mode the gamepad is in.

The indicator light will flash until it detects a suitable driver on your gaming system. The indicator light will then shine constantly. Modes can be forced by long holding the HOME button.

Input Modes: ZD V Full Vibration Feedback Wireless Controller Gamepad Joystick

Input Modes: ZD V Full Vibration Feedback Wireless Controller Gamepad Joystick

  • Use the XInput mode to enable the full vibration feedback feature. It is recommended for PC / XBOX360 games that have been written to provide vibration feedback.
  • Use the Direct Input mode for the PS3 and other platforms like the Raspberry Pi.
  • Use the Android mode when paired with an Android device.

Note: the full vibration feature will only work in XInput mode AND when the games have been written to support it.

Exchange D-PAD and LEFT STICK Functions

A great feature of this gamepad is that the D-PAD and LEFT STICK controls can be swapped easily, back and forth, by pressing BACK and the LEFT STICK BUTTON at the same time.

Ecoair DD1 Mk5 Dehumidifier

EcoAir DD1 Classic MK5 Desiccant Dehumidifier

For the purpose of clarity, this is a review of the EcoAir DD1 Classic Mk5 Desiccant Dehumidifier (formerly DD122 Classic), purchased with hard-earned cash.

Overview

The EcoAir DD1 Mk5 Desiccant dehumidifier sets the bar for home desiccant dehumidifiers with its innovative design and a wealth of comprehensive features that optimize performance and save energy. It rectifies problem areas quickly and maintains them intelligently by toggling between full power, economy and standby modes as it senses the environment around it. This means that once your environment is under control, dehumidification requirements will be adjusted continuously so that power is only consumed when absolutely necessary. It works effectively at cold temperatures, even as low as 1ºC. Its operating range of 1ºC-40ºC makes this machine incredibly versatile for use in almost any home enclosure.

EcoAir DD1 Classic Mk5 Desiccant Dehumidifier

EcoAir DD1 Mk5 Classic Desiccant Dehumidifier

The EcoAir DD1 Classic Mk5 Desiccant Dehumidifier can be used to dry laundry indoors quickly yet keep humidity levels within a comfortable range. Clothes dried with the assistance of this dehumidifier smell fresher than those dried more slowly indoors.

The 3D-Louvre on top of the machine can be controlled to tackle problem areas quickly, like mould growth on a wall, by channeling airflow towards a target in a precise manner.

3D-Louvre

3D-Louvre

The selective Ioniser purifies the air by releasing negative ions from the air outlet. This has a normalizing effect on the human body, providing ideal conditions for breathing and relaxation. A silver filter traps airborne particles and kill bacteria on contact. The filter is designed to be cleaned very easily.

Desiccant technology means no more noisy compressor at the heart of the machine. This model is advertised as Whisper Quiet at only 34 dB(A). Measurements made confirm this fact, but whether or not you could sleep with this unit running in the same room is a moot point. However, it is barely audible at night when operating on a landing behind a closed bedroom door.

Review

Design

The EcoAir DD1 Classic Mk5 Desiccant Dehumidifier is impressively smart and fashionable in design and would compliment most decors and furnishings. It is slender enough to tuck away in a corner when not in use. And, it does not seem obtrusive at all when brought out for use. The blue light in the front grill is in vogue with modern appliances and rounds off a very pleasing design.

Operation

The push button controls on top of the unit are intuitive and easy to press. The dehumidifier can be programmed for simple or specific tasks with just a few button presses.

Essentially, the amount of noise emitted from the machine is governed by the two power settings, economy and high. The type of sound that is created is akin to the noise made by the fan in an extraction hood, common to most kitchens. If you want some idea of how this unit will sound, and more importantly, how loud it will be, go into your kitchen and listen to your extractor fan on low and high settings. The video below compares the sound from the EcoAir DD1 Classic Mk5 Desiccant Dehumidifier with the fan of an extractor hood. Sound intensity levels from both units are also measured and displayed for comparative purposes. Advertised as Whisper Quiet at 34 dB(A), measurements made during the making of this video confirm that the intensity of the sound emitted is correct. However, the type of noise created is unlike a whisper, and in my opinion, it is not pleasant to listen to. Nontheless, behind a closed door, the noise is barely noticeable.

Sound measurements taken at a distance of 1 metre (3ft) from all sources.

On the high power setting, the EcoAir DD1 Classic Mk5 Desiccant Dehumidifier will dehumidify a room to comfortable levels within a very short period of time. Additionally, the unit will dry partially dried washing very quickly and wet washing reasonably quickly, and at the same, heat the room and maintain a comfortable humidity level. Clothes dried rapidly in this way smell fresher than clothes that are dried more slowly on radiators or airers. Although this dehumidifier cannot compete with the drying times of tumble driers, the EcoAir DD1 Classic Mk5 Desiccant Dehumidifier is a viable alternative for those seeking to dry their laundry in a smarter way; where space is at a premium or home occupancy is low.

This model uses 300W and 590W of power in economy and high power modes respectively. You can calculate the cost of using this appliance by entering these details and your electricity tariff in this calculator. To give you an idea of the energy cost, you will also need to enter how often you expect to use this device.

Don’t be alarmed when you see the prediction! The EcoAir DD1 Classic Mk5 Desiccant Dehumidifier really is an efficient device. This means you will not need to run it as often as you first thought. It will get humidity levels in your home under control very quickly and then it will be a case of running the unit when needed to maintain those levels, or to dry laundry effectively.

Change your habits

Condensation will not disappear instantly when a dehumidifier is in operation. If you are generating excessive amounts of water vapour from cooking, boiling a kettle, washing, showering or bathing, it will be necessary to ventilate your property by opening windows and using extractor fans to expel the excessive humidity.

Digital Temperature - Hygrometer

Digital Temperature – Hygrometer

Invest in a digital hygrometer that will measure and display the humidity level of the room you keep it in. Switching on your dehumidifier only when humidity levels are excessive will keep your energy costs low. If you own a home weather station or a modern smart phone, then the chances are that you already have a hygrometer at hand.

Conclusion

Positives:

  • Sleek, modern design and aesthetically pleasing. Its slender design makes it easy to store.
  • Incorporates intelligent features that run in parallel to optimise efficiency and reduce power consumption.
  • Desiccant technology means a consistent extraction efficiency over a large temperature range. Extraction rate of 7 Litres/day @ 20ºC and 60% RH.
  • 2 Litre water collection tank capacity with the option for continuous drainage.
  • No compressor means a quieter product.
  • 3D-Louvre system can target problem areas by channeling airflow precisely.
  • Purifies the air with negative ions to aid breathing and relaxation.
  • Silver filter scrubs air particulate matter and kills bacteria on contact.
  • Dries laundry very quickly while maintaining comfortable humidity levels and thereby preventing condensation.
  • Works so effectively that you will use it occasionally rather than continuously. This keeps energy costs down.
  • Built in shutdown timer.
  • Lightweight and easy to carry at only 6Kg.

Negatives:

  • Although the intensity of noise produced is low and in keeping with that stated by the manufacturer, the type of noise produced in unpleasant to listen to, especially in the high power mode. However, the noise is barely detectable through closed doors. That said, deployment times and locations can be organised so as not to annoy people in the home.
  • Although this dehumidifier contains a hygrometer to measure the humidity level around it, it does not display that measurement. This would have been a useful feature.
  • The humidity thresholds at which the dehumidifier switches to economy, high power and standby modes are preset and cannot be altered. The option to change these would have been beneficial for refining power savings.

A very good product and value for money.

Humidity Guide

There will always be water vapour (or moisture) in the air. Water vapour in the air is measured as the ratio of the actual amount of water vapour in the air to the amount it could hold when saturated, and expressed as a percentage. This measurement is known as % Relative Humidity (% RH). Too much or too little moisture in the home can be unhealthy and uncomfortable. The optimum humidity range is 40% – 60% RH.

It is important to maintain a consistent humidity range to preserve your home and possessions and at the same time, remain comfortable and healthy.

Low Humidity

If indoor humidity is too low, this can lead to excess drying which in turn can cause skin irritations, eczema, chapped hands and a dry nose. It can also cause damage to wooden furniture, musical instruments and works of art by drying them out too much.

High Humidity

High humidity indoors causes condensation and damp. The damp left by condensation can damage plaster, wall paper, furniture, vehicles, timber, windows, doors and clothes.

Damp areas are breeding grounds for anaerobic bacteria in the air, which land in patches of moisture and then thrive, ultimately resulting in visible mould, fungus and the accompanying musty smells.

% Relative Humidity Guide

Condensation

The graph below shows the relationship between temperature and the amount of water that can be held in the air at 1 Atmosphere of pressure.

Amount of Water in Air (g/Kg) Versus Air Temperature | Graph calculated from http://www.lenntech.com/calculators/humidity/relative-humidity.htm

Warm air has the potential to hold more moisture than colder air. When the air inside the house becomes colder, the moisture content in the air can no longer be held as the air becomes saturated and water molecules coalesce to form droplets of water on colder surfaces like windows, bathroom mirrors and walls. This is condensation caused by a rapid increase in % relative humidity.

  • A precision Torx screwdriver set.
  • A flat blade screwdriver with a long shank to assist with leverage.

Tools Required to Dismantle the MH-25 Battery Charger Case

Tools Required to Dismantle the Nikon MH-25 Battery Charger Case

For any electrical repair on the circuit board, you will need:

  • A soldering iron with a fine tip.
  • Solder.
  • Sheathed wire.
  • Wire cutters or scissors.
  • Long nosed pliers.
  • A knife.

Work in a well lit area and consider having the means to magnify the pcb board if your eye sight is poor.

Step 3 – How To Take the Nikon MH-25 Battery Charger Apart

The Nikon MH-25 battery charger is held together with one small Torx screw and lots of glue.

The Single Torx Screw on the Rear of the Nikon MH-25 Battery Charger

The Single Torx Screw on the Rear of the Nikon MH-25 Battery Charger

The head of the Torx screw can be seen at the rear of the charger, next to the power connector. Unscrew it and store it safely at one side of your work area.

Using the flat bladed screwdriver, start to work your away around the unit, applying gently pressure to prise the two halves of the case apart. The glue is strong and this part of the procedure may take some time. You can see in the image above, the small amount of damage that is inevitable in prising the case apart.

When the back of the case is removed, the circuit board, rotary power connector and spring battery clip can be taken out easily.

The Rear of the Nikon MH-25 Battery Charger Case Removed

The Rear of the Nikon MH-25 Battery Charger Case Removed

WARNING:

The rear of the Nikon MH-25 circuit board has two areas clearly labelled Primary and Secondary.

The Primary circuit deals with transforming incoming voltage to the lower voltage requirements of the Secondary charging circuit. It is possible to receive an electric shock by touching any of the points in the Primary circuit even when mains power is disconnected. The capacitors will hold charge for a significant period after mains power has been removed. The capacitors should dissipate their charge to reasonable levels a few minutes after the removal of mains power.

Step 4 – Inspect the Nikon MH-25 Printed Circuit Board

More than likely, most faults will be on the underside of the circuit board; the side with the printed tracks.

An examination of the printed circuit board from my Nikon MH-25 battery charger shows the track-side to be peppered with indentations and other mechanical induced marks. In my case, there are clear pot-marks on the incoming power rail, which have caused my unit to fail.

This youtube video shows an example where solder joints have not been completed properly during the manufacturing process and a small knock can be enough to dislodge components from the electrical circuit.

However, it is worth taking a look at the electronic components too while the board is out of the case.

Top side / component side of MH-25 pcb

Check the condition of the capacitors. Look for capacitors that may have blown and replace them if necessary.

Bottom side / pcb side of MH-25

Look carefully at the tracks and solder points all over the board. Look for poorly soldered / loose joints and tracks that appear to be damaged or broken.

Re-solder loose/dry joints. Patch broken pcb tracks with solder and wire.

In order to solder to a broken rail, use a knife to scrape away the green insulation to reveal the copper surface beneath.

Scratching away the discolouration on the pcb track with a knife clearly shows that this part of the track is broken too.

Broken tracks can be bridged with wire and solder. In this instance though, I decided to bypass the pcb track all together and run a sheathed wire between the two solder points rather than make another fiddly repair on the same track.

Step 5 – Reassemble the Nikon MH-25  Battery Charger

Reassembly of the Nikon MH-25 battery charger is relatively easy to do provided you follow these steps.

  • Take the rear part of the MH-25 battery charger case and lay it flat on your work surface.
  • Slot the circuit board on to the charger case.
  • Put this assembly to one side.
