2 Essentials of a Digital Camera


In addition to the camera body and the lens, there are many other essential elements for certain shots. In addition to memory cards and batteries, the photographer’s basics, the technical range expands according to your desires: lens hood, camera bag, flash, tripods… for each shot, its appropriate accessory.

The essentials:

– Digital camera card

– Camera battery

No photo without a memory card or battery! Remember to bring spare parts for these essentials.

The memory card is an essential element for the storage of digital pictures. It exists in different formats with different characteristics and is more or less powerful.

Digital camera: function of a memory card

The memory card is used to store photos taken with a digital compact, a bridge, a micro four-thirds or a reflex.

The pictures can then be transferred via the camera and a USB cable to a computer hard drive or other storage systems.

The card can also be taken out of the camera to be read on a digital frame or a specific card reader. Card readers allow for faster data transfer.

2 main types of digital camera card

2 Essentials of a Digital Camera

There are two main types of camera cards:

– The CF card (for Compact Flash): if it tends to disappear from the median ranges, the CF card is still very present on high-end cameras.

– The SD / SDHC card: is a universal format that is also found in cameras or cell phones

Good to know: the format of the card is determined by the device. However, there are SD adapters for cameras that use CF cards.

How to choose a memory card?

2 Essentials of a Digital Camera

Several criteria are taken into account when choosing a card:

– Reliability: it is better to turn to the reference brands to avoid the risk of seeing a report disappear without explanation.

– The storage capacity:

o It is determined according to the number of photos you plan to take on average between each image download.

o It also significantly depends on the weight of the pictures with a 21-megapixel camera, so it’s better to plan.

o If you want to make videos, you also need ample space on the card.

o When you have the choice, buying two 32 GB cards rather than one 64 GB card is better. Because if you lose one, or it gets damaged… you don’t lose everything.

– The flow:

o Not all cards have the same writing speed.

o If you have a high-performance camera, it is better to have a card that keeps up with speed so as not to slow down the shooting in burst mode, for example.

o Thus, a card with the mention 266x will be preferable to its equivalent in 133x.

Camera battery

2 Essentials of a Digital Camera

A camera’s battery is an essential element, without which it would be impossible to take digital photos. It provides power to the camera body and all connected electronics, except for the external flash.

What is the purpose of a camera battery?

The battery is the sole source of power for the digital camera. It is what powers all the electrical components.

Nowadays, batteries and other batteries consume less energy and at the same time become more powerful.

It is also possible to equip yourself with a grip on specific reflex cameras. This accessory embeds two batteries and allows a better grip in portrait mode. Tips: it is always recommended to have at least one spare battery to avoid the risk of being without a camera in the middle of a hike or during a wedding…

Different types of batteries

There are three main types of batteries for digital cameras:

– Lithium-Ion which have a relatively short lifespan but is easy to recharge. 

– The Ni-Mh have an average lifespan.

– The Ni-Cd has a longer life. Their average autonomy is rather interesting, but their price is quite high.

They contain products that are very harmful to the environment, such as cadmium. Considering the composition of these products, it is necessary to take care to recycle them well.

Flashes and other accessories still use AA or AAA batteries.

Where to buy a battery?

Consumerist logic pushes manufacturers to develop different battery formats for each model.

– Proprietary batteries are still recommended. They are sold on the Internet and in large stores or specialized stores.

– However, some sites specializing in batteries and other batteries provide quality material at a more attractive price. Compatibility is usually assured, but it is best to ask around and consult user reviews.

Controllers and Thermostats for Water Heater Radiators

Controllers and Thermostats for Water Heater Radiators

Controllers and Thermostats for Water Heater Radiators



    – Aquastat: basic thermostat present on all heaters

    – Room thermostat: indispensable!

    – Heating programmer: comfort and savings

    – Outdoor sensor: to anticipate climatic variations

    – Thermostatic faucets or thermostatic valves


Many devices regulate and program heating or domestic hot water production. They allow you to handle your different heat sources better and control your consumption.

Aquastat: basic thermostat present on all heaters

Every heater has at least a straightforward thermostat placed on the heating water circuit or heater:

    – This basic heating programmer is present on the heater itself.

    – It has the function of a heating controller: it measures the temperature of the water circulating in the circuit and keeps it constant and at the set temperature display.

    – However, it only measures the system’s internal temperature and is indifferent to the temperature of the rooms. But by varying it manually, you can regulate your heating!

Room thermostat: indispensable!

Room thermostats are very widespread, and they allow you to set a set room temperature throughout the house (18°C, for example):

    – Connected directly to the burner of the heater, it plays the role of a heating regulator since it modulates its operation to maintain the temperature constant.

    – Installed in a reference room (living room, hallway) where the temperature is supposed to be homogeneous, at the height of 1.50 m from the floor (avoid an outside wall), it allows you to correct temperature variations within the house.

    – Economical, starting at $20, a room thermostat allows energy savings of up to 10%.

    – Available with or without wire, it is now often coupled with a heating programmer.

Heating controller: comfort and savings

The heating programmer is an electronic device that the user can set. You can take advantage of it in several ways:

    – Heating controllers switch on and modulate the heating according to the programmed times and days. They typically offer 3 different regimes:

        ◦ comfort mode where the heating operates normally: evening or weekend;

        ◦ economy mode where the heating operates weakly: during the night or short absences;

        ◦ frost-free mode where the heating is on standby: extended absences.

    – Heating programming can be done:

        ◦ according to time: from 7:00 a.m. to 9:00 a.m., for example;

        ◦ according to the time of day: day/night, morning/afternoon/evening;

        ◦ according to the day of the week: workdays/weekends.

    – Three highlights of the heating programmer:

        ◦ Energy savings: you only heat when necessary! If during the day the house remains unoccupied, you can choose to program the heating in standby mode from 10 a.m. to 6 p.m., for example.

        ◦ Increased comfort: the heating programmer allows you to anticipate your needs. For example, the bathroom heating will turn on 30 minutes before you wake up.

        ◦ Functional and automatic: once the programmer is set, you don’t have to touch anything!

    – The price of a heating programmer is between $150 and $300. The device quickly pays for itself through the savings generated.

Outdoor sensor: to anticipate climatic variations


The outdoor sensor among the various heating programmers allows you to anticipate climatic variations and thus maintain a certain level of comfort inside.

    – The outdoor sensor measures the temperature outside the house. It is recommended to place it on a north or northwest wall.

    – The temperature sensor transmits any change in the outside temperature to the heater’s heating controller, which automatically adjusts the heater’s speed accordingly.

    – An outdoor sensor keeps the temperature inside the house constant, regardless of weather variations, while shortening the standard response time of the system.

    – Prices start at $40.

Thermostatic faucets or thermostatic valves

Controllers and Thermostats for Water Heater Radiators

Always with the objective of optimized and comfortable heating, there are thermostatic valves, which are mounted on water radiators.

    – The thermostatic valve allows to regulate independently the heating of the radiator on which it is mounted, and thus modulates the temperature according to the room and its use (bathroom and bedroom do not require the same comfort).

    – Thermostatic faucets or valves vary the temperature of the water circulating in the radiator, so you don’t have to change the heating speed. Setting the thermostatic valve to 5 will not make it heat faster!

    – Expect to pay between $20 and $40 per valve, or $60 including installation.

Bike Speedometer

3 Steps to Install a Bike Speedometer

3 Steps to Install a Bike Speedometer



Step 1: Mount the base and monitor screen

Step 2: Mount the transmitter

Step 3: Mount the receiver

An odometer or speedometer for bicycles is the first accessory the amateur cyclist wishes to install on his leisure machine.

Two families exist:


A true symbol in terms of a speedometer is often a dial with a needle whose position varies according to the speed.

Advanced versions show a totalizer of kilometres travelled.

The digital odometer:

More modern with its digital display of speed.

It indicates not only the speed in a precise way but also parameters that its analog counterpart cannot give: average speed since the start, average speed between two points, etc.

All speedometer models consist of three components:

  • a transmitter;
  • a receiver;
  • a box and cable (except in the case of a wireless speedometer, of course).

The installation of these elements is done by clipping or screwing and, in all cases, remains simple.

Here are the steps and the necessary material to install a bike computer.

1. Mount the base and the monitor-screen

Bike Speedometer

The assembly of the housing (i.e. the base) is carried out in the following way:

  • Clean the handlebars with a sponge and soapy water: the area where the housing will be attached must be clean to fit properly.
  • Dry carefully with a lint-free cloth.
  • Unscrew the mounting system. Many manufacturers have opted for a clamp fastening system. With a self-tightening nut, this clamping system is perfect for limiting the loosening of the nut during vibration.
  • Insert the clamp around the handlebar.
  • Insert the screw and a washer (to increase the screw’s grip).
  • Screw into a self-tapping nut.
  • Tighten securely with a screwdriver and open-end wrench.
  • Place the monitor on its base.

Good to know: some bases clip onto the handlebars, making installation even easier and allowing you to remove the speedometer from the bike easily.

2. Mount the transmitter

Bike Speedometer

A transmitter is a small plastic box with a magnet inside.

This magnet must be attached to one of the front wheel’s spokes. The fixing is done by “clipping” or by screwing.

  • Clean the bicycle spoke on which the transmitter will be positioned with alcohol (or any other degreaser).
  • Place the transmitter on the spoke:

To determine the height, refer to the computer manufacturer’s instructions to not install the transmitter too high or too low on the wheel (which would distort the measurement).

  • Press firmly on the transmitter to clip it to the spoke.

In the case of a screw mounting, fit the transmitter around the spoke and tighten it with a screwdriver.

Good to know: some transmitters can be mounted on two spokes. The mounting system is simple.

3. Mount the receiver

Bike Speedometer


The receiver is an essential element. It will “receive” information converted into speed and transmit it to the speedometer box. Its positioning must be precise and stable over time. Always refer to the speedometer manufacturer’s instructions so that the receiver is not installed too high or low.

Here is the installation method:

  • Unscrew the screws of the clamping brackets.
  • Insert the receiver on one of the front wheel fork posts.
  • Tighten the screws slightly. The tightening must allow an adjustment! Be careful not to overtighten.
  • Turn the wheel so that the transmitter faces the receiver. If this is not the case, change the position of the receiver.
  • Tighten the receiver mounting screws completely as soon as the transmitter and receiver face each other.
  • Route the receiver cable to the housing on the handlebar. Run the cable along with the bike frame, securing it at regular intervals with tape or plastic cable ties.

Good to know: some bike computers are wireless and even faster to install!

For proper operation, don’t forget to specify the diameter of the bike’s wheels on the speedometer box! Refer to the manual of your computer.

All you have to do is test your bike computer by turning the front wheel in a vacuum:

If the speedometer lights up, the installation is successful.

If not, check the alignment of the transmitter with the receiver.

Materials you will need to install the meter 

Sponge + Cloth


Phillips screwdriver

Flat wrench

Rubbing alcohol

Adhesive tape


5 Best Video Games Of 2022

There are many new games releases this year, and after the past 2 years, many people got into gaming because of the several lockdowns that we all suffered through. You can spend hours discovering this new release, and there is something for everyone, whether you play on console or on PC.

This list will help you plan out your next couple of years, especially when it comes to the video games release, and this is the guide for all the gamers out there. Are you looking for some of the best and most popular new games and releases of 2022, then look no further because we’ve got you covered. So, without further ado, let’s dive into this blog.

1. Breath of the wild 2


This is a Nintendo Switch only release, and it is one of those games that most people are anticipating this year. The first game of this series was a breath of fresh air (no puns intended) with stunning visual and genuine innovative gameplay. We know next to nothing about it, but if it is anything like the first Breath of the wild, we are in for a real treat.

This one is a continuation of the same storyline and builds upon it. The couple of trailers and snippets we saw reveals that this installment might be a bit darker in its themes. Here to hoping that this is one is open of the greatest Zelda games of all time, and we can’t wait to find out the story and all the easter eggs.

2. GTA 5 Expanded and Enhanced Edition

This game is going to be available on both the PS5 and the Xbox Series X/S. Let’s be honest for a second; we’ve all played GTA in our childhood, and most of my memory of this game is stealing cars and driving recklessly around the streets of Los Santos. This new installment to the series is coming around 9 years after the original game.

This new game boasts new graphic modes, ray-tracing, 3D audio, HDR options, and so much more, and PS4 and Xbox One players are also able to transfer their saves to this new game. This new upgraded version of GTA 5 is only a taste of what GTA 6 has in the bank, and we are excited for this confirmed next installment of this series.

3. Elden Ring


If you love Games of Thrones, you might want to try this game, as it was co-written by George R.R Martin, the modern-day bard himself. It is set in a fantasy realm of the land between, and players have to hack, dodge, slash and perfectly time their way through this realm with the ultimate hope of becoming the Elden Lord. The game was released on PC, PS4, PS5, Xbox One, and Xbox Series X/S.

The combat fundamental of Elden Ring is stronger than ever, and you have a wealth of options to specialize and customize your character. You will have many weapons and spells to support your desired play style. For people who rage quite easily, then this game might not be the one for you because it is by no means easy.

4. Pokémon Legends: Arceus

Like Breath of the wild 2, this game is being exclusively released on the Switch. This game is different from any Pokémon game you’ve played before- and we’re saying this in the best possible way. While games like Sword and Shield add new features that are a breath of fresh air to the long-running series, Arceus goes one step further: it turns the game as we know it on its head.

Thus Acting as a prequel to the main series, Pokémon Legends: Arceus takes players to a much older version of the Sinnoh region from Pokémon Diamond and Pearl (known here as the Hisui region), where Pokémon are free to roam, and you’re tasked with filling one of the region’s first Pokédex.

Pokémon Legends: Arceus focuses mainly on catching Pokémon rather than battling them with no gym ladder or badges. This new focus will be welcome for some, but others will find it a bit too far from the Pokémon formula we’ve become accustomed to. Either way, Pokémon Legends: Arceus is one of the best Switch games out there, and it’s worth discovering if you’re a Pokémon fan.

5. Dying Light 2: Stay Human


It wouldn’t be a proper gaming year without at least one zombie slayer, and 2015’s Dying Light sequel is our savior. In Dying Light 2, set 20 years after the first game, you take on the role of Aiden Caldwell, an infected survivor trying to uncover the secrets of his past and find his sister amidst a ruthless, decaying world. This game is going to be available on both the PS4, PS5, Xbox One, Xbox Series X/S, PC, and Nintendo Switch.

Aiden’s search leads him to The City (where the last human settlement is). It is then up to the player whether our protagonist focuses on his own objective or decides to help the remaining survivors by rebuilding the settlement. In Dying Light 2, the focus is on choices and consequences, with your decisions affecting the environment around you and the story itself.

The original game took the parkour of Mirror’s Edge, mixed it with a zombie shooter, and added a day-and-night system to boot. Dying Light 2 takes it up a notch, focusing on stealth, parkour, and optimized equipment to traverse the environment. With a map four times the size of its predecessor, packed with NPCs, side quests, and challenges, Dying Light 2 is perfect for those who love open-world survival horror. Both games are the perfect games for all the horror fans out there.

Top 5 Best Tech Gifts For Father’s Day

Father’s day is the one time of year that most of us show our love and appreciation for the father figure in our life, and this is usually done under the guise of a gift. Even though we deeply appreciate the presence of our father-figure (be it your biological or adoptive father or the man who acted as the father-figure in your life), we rarely say it.

This is the one time of the year when we are able to do it without sounding corny and too emotional. Father’s day is a capitalistic holiday, and we can all cope with that, but we live in a capitalist society, and we might as well celebrate it. So, without further ado, let’s dive into this blog and learn some of the best tech gifts to give your father-figure.

1. Kindle


If your dad is a bookworm like me, then this is the perfect gift for them; instead of buying them a book this year, go ahead and make the big jump and buy them a kindle. It allows you to download thousands of books straight on the device, and you can read them offline on your library.

It is ultra-portable and has a natural-looking e-ink display which has a resolution of 167 pixels per inch and now even features a front line. It also has a battery life of weeks after a single full charge. It is also pretty inexpensive and is available in 2 colors: black and white.

2. Modern Vinyl turntable

If your dad is a music lover and collects vinyl, then this might be the perfect gift for him. Nowadays, most of us stream our music, but some people still prefer the old fashion vinyl, and if your dad is someone like that, then this might be the best father’s day gift for him.

The Fluance RT81 is the perfect entry turntable for your dad and is compatible with your existing record collection and is affordable, easy to use, has a built-in preamp, and supports 33-1/3 and 45 rpm playback. If your dad is an avid music listener and collects vinyl, then this might be the perfect addition to his collection.

3. Electrical screwdriver


Most of our dads are really into fixing things themselves, even if they have to call up a professional later on, to fix what they were trying to fix. The thing is, they love getting their hand dirty and fixing things around the house. An electrical screwdriver can be the perfect companion in future DIY endeavors.

Get them the new Craftsman Max 4V Cordless screwdriver with 10 screw bits. It is a universal tool that your dad will thank you for. It’s possible that they already have one but get them either, as the one you get them will have an emotional resonance.

4. Mirrorless camera

In the past couple of years, Sony has built some of the better mirrorless cameras on the market, and the Alpha A6000 is the perfect example of this masterpiece. The Sony Alpha A6000 comes with a camera body and a 16-50mm lens. This means that this camera has everything you need to get started right off the bat.

You can always add-on to it, but it is perfectly usable as-is. It is also relatively easy to get a grasp of how to use it, and compared to other cameras on the market; it is also relatively inexpensive. While most mirrorless cameras currently on the market cost on average a thousand bucks, this one shines because its retail price is only $650.

5. Apple Watch


The Apple Watch continues to be an excellent gift for Dad. The Series 7 is the latest model with health tools like a blood oxygen sensor and an electrocardiogram that can help him keep track of his heart health. The Apple Watch Series 7 also ensures he receives notifications when he doesn’t have his iPhone with him or nearby, making it easier to contact him.

The new model also features an updated display design with narrower edges, making it easier to see the time and other “complications” than previous models of the Apple Watch. Apple has also made the Permanent Display brighter, so it’s easier to see the screen when you glance to check the time.

Let’s Talk about Transistors (Part One)

The transistor is the most important component of today’s electronic circuits, and it is essential for the realization of digital circuits. A modern microprocessor like Intel’s Core i7 can contain more than 700 million transistors. All this makes the transistor one of the most important inventions of the 20th century.

Although some active components such as diodes are capable of allowing current to flow in one direction only, with these we cannot perform an essential task in any electronic circuit of moderate complexity: the control of a signal with another sign. It seems important to have a component that allows to control the conditions of current (i)-voltage (v) by the electrical signal that passes through it, and that is able to modify these conditions according to a second signal (control signal).

A Bit of History

At the beginning of the 20th century, “triodes” appeared, 3-terminal devices consisting of a vacuum valve to which a control electrode (called a grid) was added to modify the flow of electrons from the cathode to the anode. The invention of the triode was the consequence of many almost simultaneous works, being the first patent filed by Lee De Forest for a very similar device (it had 3 terminals, but it did not work in vacuum) that he called “Audion”.

The main problem with triodes was their large size and power consumption. As the knowledge of solid state physics progressed, research began on the possibility of using this new knowledge to develop a device that would perform the function of these valves. And it was from the experiments of John Bardeen and Walter Brattain, conducted in 1947 at Bell Laboratories in the United States, with work group leader William Shockley, that the three co-invented the modern bipolar transistor, for which they received the Nobel Prize in Physics in 1956.

Types of Transistors

There are two groups of transistors, on the one hand bipolar transistors (also called bipolar junction transistors, or simply junction, “Bipolar Junction Transistor”, BJT, for its acronym in English). On the other hand, there are the field effect transistors, which in turn are divided into transistors such as JFET, MOSFET or IGBT, their operation is similar and they can be considered as modified versions of the bipolar transistor, although they will be discussed later.

Bipolar Transistors

A bipolar transistor consists of three doped semiconductor regions. As is well known, semiconductor components are insulators in their pure state, but they can be converted to conductors by adding small amounts of doping elements. A BJT consists of two regions of the same type (N or P) separated by a region of opposite type. Each of these is connected to one of the three terminals of the device, called emitter, base and collector. Depending on whether the separating region is P-type or N-type, it is referred to as an NPN-type or PNP-type bipolar transistor.

The picture above shows a conceptual representation of the structure of a junction transistor, NPN type. As can be seen, the low-doped, high-resistivity base (P-type) separates the N-type semiconductor regions. The base-collector junction is much larger than the emitter-base junction. For this reason, since the emitter doping is higher than the collector doping, BJTs are asymmetric, i.e., the emitter and collector terminals are not interchangeable, which could also lead to different behavior in our circuits.

Although there is a lot of relevant information about bipolar transistors, in short, the fundamentals about them have been mentioned. Do you still want to learn more about them?

Top 6 Glitches that the Ps5 Is Facing

The PS5 is here, with the Xbox Series X and Xbox Series S, ushering in the next generation of consoles. Thanks to its new bespoke CPU and GPU, as well as its new ultra-high-speed SSD, the PS5 adds a slew of new capabilities and improves system performance.

Bugs in software and hardware are normal, but they will obstruct your pleasure in your new console. However, every new console generation brings with it a new set of problems and faults. We’ve compiled a list of all known flaws and difficulties, as well as any known workarounds that may be useful.

The PlayStation 5 comes with a new operating system and a slew of innovative hardware features on both the console and the controller. Changes made don’t always operate as expected, and they’re generally fixed within a few weeks of their discovery.

Top 6 Glitches that the Ps5 Is Facing

Having Trouble Connecting To The PlayStation Network

Some PlayStation Network users have reported having trouble connecting and downloading games. The best thing to do if you’re having problems is to verify your wifi connection and try again. You may also look at the Network Service Status to determine whether the service is experiencing any problems.

There’s a massive rush of customers wanting to login in, download, and update their new consoles, so give yourself plenty of time for setup, especially if you’re using the digital version.

Ongoing Power Issues With Your Ps5

If your PlayStation 5 loses power soon after turning it on, won’t switch on at all, crashes or freezes while playing, or turns off while playing, it might be down for the count due to an internal power issue. If this happens, you’ll need to troubleshoot your system on the PlayStation website to see if you’re qualified for a repair.

Uninstalling Game Once the Disc Is Removed

Users have reported that games have been uninstalled from their systems after removing the disc. We have a solution for you if you’re facing this problem. Allow the PS5 to install the game on its own after inserting it. Do not choose Manually Copy. If the installation does not begin, restart the console and try again.

Strange Screen Flickering During Game

Your PS5’s GPU might be to blame if your game is flickering, stuttering, or has any other screen oddities. If this is the case, contact Sony for more assistance.

Crashing or Rebooting to a Black Screen

It might be a problem with your HDMI connection if your game crashes and reboots to a black screen. Turn off your PS5 and TV, unhook the power, detach the HDMI connection, then reconnect to troubleshoot. The connection between your console and television should now be restored. If at all possible, try a different HDMI cable.

My PS5 is overheating.

When their PS5 overheats, some customers have reported seeing an error message. This might indicate that the system isn’t properly vented. If you encounter this message, follow these actions to resolve the issue:

  • Do not store it in a cupboard or any other enclosed space.
  • Because the fan is located behind the faceplate, the console is primarily intended to keep it unobstructed, thus avoiding blocking it.
  • Do not cover it with a cloth or place it on a cloth.
  • Make sure there’s some room between it and the walls.

If the problem persists, it might be a fan problem with the console. Additional troubleshooting should be sought from Sony.

It is totally normal that the not-so-new PS5 is facing glitches. This is what happened to any new gadgets on the market that why it is still important to have a waiting time for the company to fix all the glitches before buying. Even if some people have been disappointed Sony Interactive Entertainment has come up with a different update that fixes bugs and provides a better version of the console. Have you ever tried the new Ps5 yet? Let us know in the comments…

Ergonomic Mouse

What Is an Ergonomic Mouse

What Is an Ergonomic Mouse


    – Differences between vertical mouse and classic mouse

    – Characteristics of the vertical mouse

    – Price of the vertical mouse

When the hand’s wrist and fingers are badly or too much solicited, the hours spent in front of the computer can cause pain in the long run. Some computer tools, such as the vertical mouse, prevent or alleviate this.

Differences between a vertical mouse and a conventional mouse

The shape of the vertical mouse

The main difference between a vertical mouse also called an ergonomic mouse, and a traditional mouse (or computer mouse) is its shape.

This shape, which is higher up, and the distribution of the buttons allow:

    – To maintain the forearm, the wrist and the hand vertically, in a position close to their resting position

    – To optimize the use of the fingers

Health benefits of the ergonomic mouse

A vertical mouse is recommended when prone to musculoskeletal disorders (MSD) or tendonitis-type pain.

Unlike conventional mice, vertical mice eliminate the need to twist the wrist and forearm. The muscular effort is therefore reduced. The adjustment of the vertical mouse buttons minimizes the use of the finger extensor muscles.

The entire shoulder-forearm-wrist-hand-finger chain is better and less stressed, preventing or reducing pain.

The characteristics of the vertical mouse

Ergonomic Mouse

The following characteristics should be chosen according to your needs: office, games, graphics, etc.

Criteria similar to the classic mouse

    – Technology: optical or laser.

    – Power supply and connectivity: wireless with battery or wired with USB connectivity.

    – Sensitivity in DPI (dot per inch).

Note: For optimal performance, the vertical mouse, like the classic mouse, must be used on a mouse pad.

The particularities of the vertical mouse

    – Asymmetry: there are different models for right-handed and left-handed users.

    – The buttons: at least 3 buttons. You can configure the functionality of each button directly on your computer or with the software that comes with your vertical mouse.

    The vertical mouse’s size must be adapted to the size of your hand; 2 or 3 dimensions can be offered depending on the model.

Tip: It is best to try the vertical mouse before purchasing, as there are different shapes. The grip should be natural. Depending on your use (office, games, graphics, etc.), the adaptation time for optimal use is from 2 days to 2 weeks.

Comfort at working

All in all, it’s critical to be comfortable and take care of your hands and wrists while you work, and if this is a situation you’ll be in for a long time, an ergonomic mouse is an obvious option.

I would tend to recommend the Logitech MX Master series which has been the best for years. Every refresh improves on the previous one, but the essential design remains unchanged, and there isn’t much that can be done to improve it.

However, it’s very pricy, and you might discover that another of these wonderful mice, or perhaps a trackball, better suits your needs. Your wrists will thank you regardless of which option you choose.

Price of a vertical mouse

The majority of vertical or ergonomic mice are priced between $10 and $50.

Some specialized sites offer a wide range of vertical mice, such as games or graphics, for specific purposes. In this case, prices range from $50 to $150.
