Different Uses of a Stopwatch That You Can Benefit From Daily
October 13, 2021
The uses of a stopwatch have been shelved due to technological advancements but not anymore! Ever since 1822 when stopwatches were first recognised, they have measured time and events. Many years later, the introduction of smart phones paved the way for what we now call the phone timer. This smartphone feature acts as countdown timers where users can keep track of multiple events at one time. Sounds familiar? However, as technology continues to advance, the functions and uses of classic stopwatches have adapted to the demands of the modern world. Not many people know it, but this device can actually help users improve discipline, mindfulness, and enjoyment around everything they do. In this post, we will define stopwatches, including their history, how they work and their functions up to this day. This guide will also show you can the uses of a stopwatch can benefit you in your daily grind. Stopwatches were not built into conventional watches until a complex version called the chronograph came along. Chronos means "time", while graphos means "to write"—when put together, it means a device to record time. A chronometer, in contrast, refers to a device used to express time accurately. A great example of this is the marine chronometer. It is an essential item used for sea navigation, with accurate and safe reading. The word chronometer is also used to refer to watches with certified Swiss precision standards. The first stopwatches were mechanical analogue devices with hands to display time. Now, most modern models are quartz digital devices. Both types are nonetheless required to perform the same functions, such as: To start and stop the time, and measure the time elapsed. Take continuous measurements by resetting the time to zero. Take continuous measurements in the smallest units needed for competitive events. Record split times and measure times for multiple competitors or tasks. Provide highly accurate and precise time measurements. Records show that time measurement functions were added to watches during the 17th century. Yet the designs for stopwatches first appeared in the 18th century. In 1695, a British man named Samuel Watson invented the "Physician's Pulse Watch", requested by John Floyer, a surgeon. The device was a pocket model that could be stopped by operating a lever. It was able to measure to an accuracy of 1/5 second. But George Graham later came up with a start-stop watch that could measure time to 1/16 second. He was a British inventor who notably contributed to the advancement of watches through inventions. The world's first stopwatch was acknowledged under the name of Nicolas Mathieu Rieussec in 1822. King Louis XVIII tasked the French watchmaker to create it, following the restoration of royalty in France. The king was a keen fan of horseracing, so the first renowned watch was for recording the times of horses. Later, Rieussec’s chronograph was used at the Champ de Mars Racecourse, on the site where the Eiffel Tower is now located. This was the first time that results were recorded based on finishing times, rather than horses crossing the line. And did you know that this mere pocket watch also made its debut to time Olympics events at the first Modern Games in 1896? But the end of mechanical timekeeping at the Olympics took place in 1960. As per Gear Patrol, it is due to the increasing precision of electronic timekeeping. Advances in technology and industry over time led to stopwatches being used over a wide range of fields. From sporting events, military to measuring the speed of cars and aeroplanes, to name a few. Fast forward to the present day, the function of the stopwatch did not change that much. But how it works and its uses promise more upgrades in the future. Unlike clocks and wristwatches, stopwatches do not tell the time of the day. Instead, it tells the person how long it took to perform a certain task. It does this using the start and stops buttons. Basically, when the start button is enabled, it will begin tracking the time until you click stop. A handheld stopwatch usually displays the time taken in minutes, seconds, and one-hundredth of a second. Moden stopwatches can record time down to a millionth of a second for more accuracy. The function A stopwatch usually has a digital screen in the centre of the buttons. This screen shows the amount of elapsed time. And the buttons on top provide specific functions, such as starting, stopping, and splitting time. Generally a stopwatch follows the below layout: The button on the left is the splitting button, used for measuring lap splits, cumulative splits, and resetting the time. The middle one changes the mode, whereas the right button is the start and stop functions. Modern models can have more features like an alarm or even a calendar function. Tip: When buying one, make sure to refer to the manufacturer's manual to see the list of all functions that come with the stopwatch you wish to purchase. The basics A stopwatch works by pressing the start button when the event begins. For instance, if you were timing a race, you would press the start button when it starts. Press the stop button when the winner has set at the finish line or when the entire race is over. The calculated time will show on the displays just as the time of day would appear on a wristwatch. Clear the watch once done so you can use it for the next game. When it comes to how you should wear it, most stopwatches do not have wristbands. You will mostly like to carry it around your neck or in your pocket. A great example of this is this stopwatch with a lanyard (TI1270). This handy stopwatch can be a useful tool for your work, training, and everyday life. It can measure elapsed time for up to 24 hours and has an accuracy of 1/100th of a second! In addition to being water-resistant, it features a split time as well as alarm and calendar functions. Advanced features There are stopwatches that feature a split button for timing parts of an event. Suppose the race you are timing is a relay, which requires a time record for each leg. Press the start button at the beginning of the track-and-field sport. When the runner has finished one leg and passed the baton to the next runner, press the split button. The slick thing about this feature is when the watch displays the time for the first relay, it continues to cumulate time for the next runner—up to the total race. Just press the split button until the relay race is over, then press stop. To record the time for each team, press split to get the score for the first relay and so on. Keep in mind that some models can only hold a certain amount of split times. Hence we recommend checking the feature list to see how many split times your stopwatch can hold. Timer The main core of a stopwatch is the timer. As mentioned earlier, the timer times how long it takes you to do something, not timing the actual event. Assume you are leaving home to go to work. Press the start the moment you step out of your front door. When you reach the office, press stop. The time it took you to get to your workplace from your house can be seen on the stopwatch. Parts A stopwatch has a display (some call it the "face") that shows all the time data. And there are two types for this one: analogue and digital. Each is divided by separations that measure hundredths to thousands of a second. Analogue has hands to express time, while digital displays it on a small screen number. We already mentioned this, but both analogue and models have action buttons. These buttons let you start and stop time, or restart the count, make a lap, or split the count into partial times. A stopwatch, both analogue and digital, can measure time in three ways: Cumulative. This records how long it takes between one event and another. For one, the time is taken for an athlete to go from the starting point to the finish line. Laps or splits. This shows the time between a series of events, such as how long the runner runs each lap. Cumulative and laps. This measures the time between a series of events and in total. For instance, the time taken for a sprinter to run each lap and the entire race in total. Digital stopwatches are common in laboratories. They can measure a time interval up to 0.01 seconds, indicating the time lapsed as the start/stop button is pressed. The time interval is recorded between the start and stop of an event. See the accumulated numbers on the screen to note the time. The reset button restores its initial zero settings and you can start timing the next activity. Mechanical stopwatches measure a time interval up to 0.1 seconds. They feature a knob that is used to wind the spring that powers the watch. This lever control can also be used as a start-stop and reset button. The stopwatch will start to record the time when the knob is pressed. When pressed the second time, it stops. The third press brings the needle back to zero. When it comes to science, knowing how long something takes is important. This includes research, investigation, and understanding a certain matter. Scientists use stopwatches in kinetics, both in chemistry and physics, and experiments. This is to determine the following: Reaction. The time it takes before an event occurs. Speed. The time something takes in general. Velocity. The speed of something travelling in a particular direction. Stopwatches have always been important and an essential in the sporting world, too. This device makes it possible to record time as close to the mark as possible. Be it analogue or digital, stopwatches are used for three common reasons: For measuring performance and determining rank. How long it takes an athlete to run a 100m sprint, for instance? The time taken will determine first, second and third place. Part of training. Most athletes use a stopwatch for their training, tracking their performance and progress with their coach. During gameplay. Soccer matches use a cumulative and lap/split stopwatch to calculate extra time needed for timeouts during the game. Sporting events are highly competitive, every second (even a millionth of a second) counts! So time must be recorded as precisely as possible. The difference between first and second place for two athletes could be as little as 0.0001 of a second. Other beneficial uses of a stopwatch Did you know that stopwatches are also used as punch clocks? Some companies rely on this type of timekeeping for tracking their employees hours and evaluating their efficiency. The advanced setting even allow for break time adjustments. An analogue stopwatch would be perfect for you if you want something mechanically operated for monitoring time. Inaccurate timekeeping can also cause billing headaches. This is where a stopwatch comes into play for precision billing! It helps provide precise time data to ensure you nail every moment spent on projects and clients. And if you really want to go a non-digital route for setting a timer, you can time anything with a stopwatch! This includes meditation, writing, chores, work intervals, and other daily life situations. This practice gives you the sense of permission to be dedicated in whatever you decided to do and make it worthy of your time. Electronic timing did not replace mechanical timing. In fact, this mighty mechanical hand timer has proven its worth again and again. Even with electronic app timekeeping, nothing beats the accuracy and precision that a stopwatch offers for different uses. It may not be a necessity, but incorporating it into your lifestyle can also help make your daily life more manageable.
Getting Started With Outdoor Trail Cameras: A Beginner’s Guide
October 11, 2021
The idea behind outdoor trail cameras is simple, and you can take advantage of it more than you think! The world of digital cameras has expanded into a bewildering array of models and specifications. You can find a variety of event recorders on the market with different purposes, such as: DSLR cameras for photography Action cameras for adventures Trail cameras for wildlife watching You may or may not have heard the last one before, but what do you think of when you hear the words "trail camera"? The hint is already given—even so, it can be more valuable than that. This beginner guide to outdoor trail cameras aims to help you understand the nuts and bolts. You may also consider this your buying guide to find the best trail camera that fits your needs! Picture this. You spotted an animal in the middle of a forest and you want to take a closer look or a photo of it. Chances are your movements would alert the animal and it will flee. This is where trail cameras come in handy. They can capture close-up, freeze-frame images of animals without bothering them. Also known as scout cameras, outdoor trail cameras are often used by hunters. Wildlife researchers and homeowners find this device valuable, too, not only for wildlife watching but also for: Establishing migration for the animals Identifying places for feeding routes Home security system They make the ideal camera for checking up on wildlife, on what they are up to when you are not around. Whether you are interested in hunting or just observing them, a trail cam can be a helpful tool. You can get clear, detailed images of animals without running the risk of scaring them off. Or track the exterior of your property for wildlife intruders; use it as a home security camera alternative. For one, for monitoring your pets at home when you are on vacation or keeping an eye on wildlife intruders coming into your yard. There is also a trend going on blogs and video sites about "bloopers" of wildlife caught in goofy moments. Who knows? One day, you would be also surprised and delighted by the variety of animals your trail cams has recorded. You could get it viral, too! Trail cameras are designed to exist in a state almost like a TV left on standby. The piece that is operating 24/7 is the motion detector. Most trail cams feature a Passive Infrared (PIR) detector. This type of sensor is the same as those seen in burglar alarms. When the PIR detects motion, it alerts the rest of the camera and triggers a domino effect. Basically, this is how an outdoor trail camera works: The light levels are detected and the flash is turned on—focus is set—shutter speed is determined—pictures or video are taken by the image sensor—the data are stored on an SD card—the camera goes back to 'sleep' (except for the sensor). In short, once you install the camera in your animal activity area, you can leave it to do the work. When passing wildlife trips the motion sensor, the cam will snap a picture or record a video. Modern models can take coloured images/videos during daylight. And black and white at night using an infrared (IR) flash, as opposed to the white-light flash of a conventional camera. A spot with signs of animals (e.g. animal tracks, woodland edge, or along a stream) On a stable location (e.g. tree trunk) Near food or water sources In a shady spot At animal height There are a few key features of trail cameras you need to consider before making your purchase. 1. Ability to detect animals The key element of a trail camera is its knack for detecting animals. Experts usually recommend models with PIR. PIR can detect average changes in the thermal landscape in front of the cam and not the specific heat sources a thermal imager does. These changes in temperature occur when something moves with different temperatures to its background. The sensitivity of a PIR to detect these subtle temperature changes depends on the make and model of the trail camera used. Some trail camera units use up to three PIRs, pointing in different directions. They anticipate wildlife moving into the field of view of the camera. 2. Trigger-time This is the time between movement detection and a picture being taken. For instance, once an animal has been sensed, the trigger-time determines whether it is still in front of the cam when the picture is captured or not. A trail camera can be as fast as 0.1 seconds or as slow as 1+ seconds. This may represent the difference between photographing a fast-moving animal or missing it altogether. Thus, a model with a fast trigger-time is the real deal here. 3. Recovery-time This is the time between a picture/video being taken and the camera getting ready to be triggered for the next. There is less benefit in a fast trigger-time if the camera has to spend the next minute gathering the energy to make another attempt. The best trail camera has no recovery time at all. It keeps on taking multiple pictures in a row, so make sure not to overlook this feature. 4. Lens Most outdoor trail cameras come with a fixed-focal-length lens. This includes a fixed near-point of focus. The wide-angle lens is great for taking pictures without excluding crucial elements in the background scene. But when it comes to individual subjects, they tend to appear small on the image. A narrow field of view zoom lens, in contrast, can miss a lot of detail. If you plan to use the cam for photographing birds on feeders, user-changeable lenses is your best bet. For one, they are specifically designed to have a very close near-point of focus. Be mindful of the type of lens for the trail camera you wish to buy. Make sure it suits the type of work or project you want to do. You can find more information on lenses on the manufacturer websites. 5. Flash The flash or illuminator in trail cameras is factory fitted. Meaning this feature is installed when the camera was being built on the assembly line. One of the important factors in which a trail cam can be used is largely determined by its flash and illuminator type. Hence the choice of model is vital; make sure the flash and illuminator are in the same unit. The lights flash on instantly when a still image has to be taken, whereas they illuminate for longer when it comes to recording video. 6. Picture/video quality While the flash type can affect image quality, the feature having the biggest impact on this is the resolution of the image sensor used. Often, the resolution is specified in Megapixels (MP). A megapixel is the number of pixels in a digital image; one Megapixel is one million pixels. The more Megapixels, the better quality the image is likely to be. The other way resolution can be specified is in Pixels (P). The differences between a camera specified in MP and one in P may seem ridiculously high. I mean, we've already said one Megapixel is a million pixels! The key here is the way we are defining the resolution. When they are specified in MP, the resolution is referring to the total number of pixels in the image. For instance, a 2MP camera could have a resolution of 1920 x 1080 pixels (2,073,600 total pixels). Alternatively when a cameras resolution is defined in P, we are just referring to the number of horizontal lines in the image, ie the number of pixels on the y axis. Thus a 720P camera could have a resolution of 1280 x 720 (921,600 total pixels). This difference is done to avoid complex numbers when describing the resolution of an image. For instance having Megapixels in fractions or Pixels in the hundreds of thousands. The resolution will also differ between photos and videos, so make sure you know the resolution for both (depending on what you are using it for). If you are finding it hard to compare cameras using the two different definitions, look for the resolution specified by both vertical and horizontal axis (1920 x 1080, 1280 x 720, 640 x 480 etc). Note the downside to a higher resolution is a higher storage requirement. 7. Memory SD card It makes sense to buy an SD card with the largest capacity you can afford, from 2GB to 128GB storage or more. But it is important to check the camera model for what the maximum capacity SD is. The file system built into SD cards is different in various capacities. For one, you may find that your chosen camera is limited to only 16GB storage capacity. So if you plan to take a lot of videos, we recommend opting for a trail camera unit that supports high capacity SD cards. You also must consider the SD card class, which refers to the speed at which pictures/videos are written to storage. To know more about the specifics, this memory SD card guide answers all your questions! 8. Power supply Outdoor trail cameras are generally powered by AA batteries within the unit enclosure. But there are models that do have provisions for external power supplies. This could be one of (or a combination of) DC—an external high capacity rechargeable battery—or a solar panel. These external power options can dramatically increase the camera longevity in the field compared to AA batteries. Moreover, they may be especially useful if heavy use of flash is needed for video. But if you wish to stick with AA batteries, be mindful of what type to use. Here are the different types of batteries, including their uses and applications. 9. Other bells and whistles Timelapse, security, walk-test, and shutter speed fall in this category. Timelapse is an extra feature to look out for. In timelapse mode, a trail camera is set up to snap pictures at regular intervals, not only when movement is detected. But some models can do both at the same time. This feature is very useful for picking up cold bodied animals that may not trigger a PIR. Or for capturing images of warm bodied wildlife that moves too slowly or is too far away to alert the PIR. Next is security. Trail cameras are expensive and there is nothing worse than returning to the site only to find that your camera has been stolen. While setting up your trail cam in a hidden place using camouflage, extra physical security will be at your advantage. There are trail cameras that also have Python cable lock to attach to a tree. There are also 'cages' which are also known as bear cages wherein the entire camera can be fitted into it. These cages feature pre-cut holes for the lens, PIR and flash. A bear cage for your trail camera will help prevent damage from the animal itself as well as against theft. A walk-test function is also essential. This is great at eliminating blind spots in the PIR's detection range, where the camera can see something but the PIR fails to trigger a picture. By moving a hand or foot in front of the cam, you can test it to see if your movements can trigger the PIR and snap a picture. To ensure greater success, do a little repositioning or tilt the camera a little in the desired part of the camera’s field of view. It is also crucial to have the option to adjust the shutter speed for your trail camera. Even if it is just at the basic level of fast, medium and slow. It is amazing how a trail camera makes wildlife photography and hunting more convenient and interesting! You can also take advantage of your trail cam by using it as a home security camera. This trick can help you capture both pesky animal and human intruders. We hope our beginner's guide will help find the perfect outdoor trail camera that suits your needs.

How Do Wireless Cameras Work: The Basics
October 7, 2021
Did you know that wireless cameras may or may not be entirely wireless? Gone are the days of long and cluttered wires running across floors and walls. Thanks to technological advancements, wireless systems have experienced significant improvements. But how do wireless cameras work? Do they really need the Internet to operate? What are the benefits and limitations of using one? Read on to find out the basics and important ins and outs of wireless cameras. Not all wireless cameras operate fully wirelessly. Some are powered by batteries, while other models must be plugged into the wall. They may not be completely cordless, but they use wireless transmission. This means you do not have to run a cable from the camera itself to the receiver. Plus, there are fewer cables to deal with compared with wired cameras. This makes wireless home security systems easier to install and more convenient to use. But why is a wireless camera is not wire-free? Basically, it is considered wireless because it uses WiFi, a.k.a. wireless internet. Hence the term ‘Wi-Fi camera’. When it comes to home CCTV systems, there are several reasons to use wireless cam units over their wired counterparts. On top of reliability and performance, they also offer greater flexibility for placement and come with extra features! Just like this 720p wireless surveillance camera kit with a 7" LCD (JQC3764). This wireless camera kit comes with a large 7" touch screen LCD, giving you full control. You can also connect up to 4 cameras (available separately—see JQC3765). This wireless surveillance kit also features a 2.4GHz RF band. The camera itself is weatherproof and has built-in LEDs for night vision and a motion detector (PIR) to automatically trigger recording. This help reduces required memory and saves review time. Power supplies and mounting hardware included. The first security cameras on the market were wired. These wired cameras rely on video cables to transmit video signals to a viewing device, such as: Computer monitor screen Television Fast forward to the present day, there are still multi-camera setups that work this way. Also known as a DVR (Digital Video Recorder) security system, they record 24/7 and you can also connect them to the internet to view remotely. But this could mean more wires are needed, resulting in cluttered cords. And just like that, many started favouring wireless cameras since their introduction to the market. As explained, the wireless alternative transmits over the internet and is powered by AC power. This means wireless cameras must be plugged into an outlet using a power cable. But other than that, there are no further wires or connections needed. Some even use Cloud storage accounts to save the video footage for later viewing. A wireless camera relies on communication between video transmitters and receivers. Most digital-video cameras come with a built-in wireless feature, allowing the cameras to connect to a computer. The receiver must also maintain a wireless connection to a monitor or time-lapse recorder. That way, the camera can capture the feed going into the receiver. Frequencies The communication between camera and receiver takes place at a frequency specific to both devices, such as: 700 MHz 900 MHz 2.4 GHz 5 GHz These RF bands offer varying bandwidth, range, and penetration capabilities. Do wireless security cameras need internet? The answer is yes. A wireless camera must maintain a good signal to record and capture footage. Therefore, it needs to be connected to your Internet network provider. If there is a disruption to your Wi-Fi, the security camera unit may not be able to send the feed to your device. A wired camera, in contrast, does not need to be connected to the internet. They can operate independently from your network. Wireless cameras address the most significant downside to wired systems: installation. Unlike wired cameras, you do not have to hire a professional to connect and install the unit to your electrical system. You can even do it yourself! In less than 15 minutes, you can set up your wireless cameras in no time. Due to the lack of wires, wireless cameras can also be placed wherever you need them. Going wireless allows you to conceal the cameras easier, as you won't be caught out by dangling wires. They tend to be less expensive than wired cameras, as well. Plus, they are easier to move and transport, and easily accessible. Another thing that we like about wireless camera systems is they provide secured footage. Most models save data directly to the cloud and are fitted with alarm monitoring services. With wireless cameras, you can back up your footage. The limitations If the camera is completely wireless, then it needs a battery for power. Thus, you need to replace or recharge the battery before it dies. Do not place a wireless camera too far away from the router. If there is a direct line of sight, its range may reach up to 150 metres or more. Within the house, the range is usually lower, around 45 metres, in some cases. The signal range depends on a few factors, these limitations include: Your home's building materials Other wireless devices in the area Any walls or objects through which the signal has to pass The reliability and performance of wireless technology have equipped us with innovative solutions to wired systems. But it turns out that the term“wireless” refers to how a camera communicates, not how it is powered. Wireless cameras are a great addition to your home and business security system. They offer you 24/7 viewing access, no matter where in the world you are. Now that you know the basics, it is time to explore the best wireless security cameras on the market. Take a look at our wireless cameras available here and see which one can integrate with your security system.
Action Camera Use: What Can You Do With Action Cameras?
October 5, 2021
Action cameras may be small in size but never underestimate their power! Going for an outdoor trip or planning to travelling abroad? Great! You better bring a camera with you to capture those epic moments and relive them through recordings. But if you plan to go on a hike, scuba diving, or mountain biking, using a point and shoot camera or smartphone may not be your best shot. You need something compact, lightweight, and as mountable as possible. Action cameras somehow manage to cram the functionality and convenience you need for those kinds of adventures. If you are thinking of investing in one, this is the sign you have been looking for! As the popularity of this incredible digital camera continues to climb, it is time to get yourself a cool gadget accessory like this to own. In this post, we will talk about the following: Defining action cameras Can action cameras be used for photography? How do action cameras actually work? The difference between action cameras and GoPro Special features you can find on an action camera (with an expert’s tip!) Conclusion Each digital camera has its own use and purpose. They also come in different types and sizes, and one of the most common uses is for photography. A DSLR camera is an ideal tool for professional photographers. A standard point and shoot one, in contrast, is the best option for beginners. And an action camera is an excellent cam companion for thrill-seeking adventure or sports enthusiasts. It takes the best elements of a point-and-shoot camera and packs it into a tiny, durable frame. But what are action cameras and what are their uses? Actions cameras are similar to how a normal digital camera functions. You can use both for shooting pictures and recording videos. The distinctiveness between the two actually comes from the form rather than the functionality. When it comes to taking quality photos and videos in all kinds of environments, action cameras are unbeatable. Most of them are small enough to fit into the palm of your hand. They are lightweight, highly portable, and are great for recording the action. The materials used for this invisible outdoor camera are impressive, too. No wonder why an action camera can withstand knocks, bumps, and jolts—and why they are used for adrenaline-fueled activities! This includes hiking, cycling, skydiving, skateboarding, climbing, scuba diving, surfing, and more. And one of the reasons why action cameras are loved by adventurers is they can be mounted on the body. Other models have some kind of mounting system for placement on bikes, surfboards, helmets, to name a few. Most are likely to have some sort of quick-start mode or button as well. Yes! There are modern action cameras that can capture high-quality 20MP photos, such as stills, bursts shots, and long exposures. Some models even feature night photo mode to control the shutter speed and nail those long exposure shots. You can even get the RAW images. This gives you more flexibility with editing in post-production. To know how an action camera works, you need to know what is inside of it and its components. Because of the miniature size of action cameras, most feature a small lithium polymer battery to operate. Batteries with higher mAh specs usually come in larger sizes. But most high-powered action cameras are capable of giving you a couple of hours worth of juice. As for the lens, an action camera itself acts as the eye. It packs a huge amount of technology into its very small glass lens. Keep in mind, though, that every unit is different, but often they feature an aperture of ƒ/2.8. Some models even have a wide-angle field of view with reduced distortion. The image sensor of action cameras is matchless, too! It acts as the optic nerve, which detects and converts the light waves into a breathtaking image or video. It is the image sensor that can provide you with 4K or 1080p video quality and 12MP for the images, as well as control the frames per second (fps). And did you know that most modern action cameras allow wireless communication? Thanks to the hardware chip that they come with, you can connect it via WiFi or Bluetooth. Modern action cams have microSD card slots to get the data for your camera’s motherboard. Choose one with a high storage capacity, especially if you plan to use your action camera for taking high-quality videos. Pay attention to the speed class, durability, and warranty, too. This curated SD Card guide has everything you need to know about SD cards. Lastly, the motherboard connects all these parts together. It is the key piece of hardware that allows fast communication between components. It works by managing all the core functions, whether it is for processing video/images or managing power. Most people think of GoPro when they hear the phrase "action camera", and for good reason! But to explain it briefly, a GoPro is one of the leading names in action cameras. It is one of the best action camera brands out there. Whereas an action camera is a variety of digital cameras—the camera itself. Action cameras open the possibility for the invention of GoPro, Sony RX0 Mark II, and other units. And this WiFi Action Camera 4k 2 Inch LCD Screen Water Proof (JQC8071) is another great option! Take this WiFi action camera with you in your travels and capture your adventures in 4K ultra-high definition. It records and stores images, video and audio to your trusted microSD. You can playback your recordings on the 2-inch colour LCD screen or stream it to your smart device via WiFi. This action cam model also has all the features you would expect from a modern and high-quality action camera, such as: Timer Burst mode Single shot Slow-motion Timelapse Adjustable exposure Wide-angle 170° lens Built-in microphone Speaker and much more! On top of these, it is supplied with seven different mounts for most applications and a waterproof case for use in above 30 meters of water depth. What separates action cameras from standard digital cameras is their power to shoot high-quality videos and photos in any environment. And these special features make it even better! 1. 4K video 4K action cameras have been available for years now, so most models support 4K videos recording. But the high-end ones can record 4K cameras at up to 60 fps. This means you get to record and achieve clear and crisp videos, even when played on smartphones, computers, or TVs. As mentioned earlier, action cameras can get stunning photos up to 12 megapixels, too. You sure do not want to miss these features when shopping for your action cam soon! 2. Waterproof The number one reason why action cameras are ideal for surfing, scuba diving, and other activities that involve water is because it is waterproof. Unlike other cameras, action cams have extra layers of protection for the lens and the body. Manufacturers have been developing water-resistant action cameras with or without a protective case. Now a camera like this Mini DV Camera Low Light WiFi & Case 1080p (JQC8102) is not just waterproof but also weatherproof! This means it can be positioned anywhere to capture the action. Even better, it measures less than 30 mm cubed and weighs just 25 grams. The 155° lens has a very broad field of view and it features eight infrared LEDs, which allows low-light recording. 3. Image stabilisation It is important for action cameras to be shake-proof. For one, users are likely to move, jump, and climb when they are filming with the cam. Fortunately, most models adopted Electronic Image Stabilisation (EIS) technology. This feature helps reduce blurring and maintain high image quality while in motion. No wonder why many extreme sports enthusiasts love these cameras for recording their adventures! 4. Mountable Action cameras are infamous for their mobility. Unlike with a DSLR, action cams are small as a hand and can be handheld or mounted to anything. You can find models that come with a set for water use or a helmet mount for when you are on a bike or surfboard. An expert's tip The key to finding an action camera that is best for you is to figure out what you are going to do with it. If you need one for diving, opt for a model with the best waterproof capability. But if you need the camera for biking, we recommend getting one with the best image stabilisation. Action cameras have overtaken traditional camcorders and compact digital cameras. And why should they not? Considering their super convenient size and being waterproof, it is no surprise why they are high in demand! They are the perfect choice of camera for capturing immersive action shots. Why? Action cameras let you become part of the adventure and capture photos and videos in a way that traditional cameras or smartphones cannot do. They also have proven to be very useful for tourists and sightseeing travellers. Filming adventures in foreign countries and at distant landmarks has never been simpler than with action cameras. Now you know why how mighty and influential action cameras are!
Microscope Set: The Importance of a Microscope for Kids
October 1, 2021
Are you thinking about buying a microscope set for kids? No biology class is complete without using microscopes. They are a great science tool that can offer an effective learning experience. But is it necessary to buy a microscope for kids? Whether it is for school or an addition to your child's maker space at home, a microscope set is essential. In this post, we will learn more about its importance as well as the ideal features you should look for. Microscopes introduced a whole new dimension into the fields of science and technology. This advanced tool aids scholars and scientists to discover and study fine detail which our eyes alone cannot perceive. This includes the existence of microorganisms, the structure of cells, and the minute structures of plants, animals, and fungi. But what is a microscope and how does it work? Micro means "tiny" and scope means "to view or look at". A microscope is a tool used to enlarge images of small objects for study. It uses visible light and magnifying lenses to detect or observe an object at the cellular level. For instance, microbes that are not visible to the naked eye. The two lenses in this instrument do the magnifying job. There is also a variety of knobs attached for resolving or focusing the picture. Note: A microscope set with more than one lens is a compound microscope. It is the most common type of microscope. The compound microscope has two systems of lenses for greater magnification. These are: Ocular eyepiece lens which you look through Objective lens which is the closest lens to the object But a microscope set is more than just two lenses. Listed below are its common parts and their functions. Eyepiece lens As mentioned above, the eyepiece lens is found at the top of the microscope where you can peek through. It usually has 10x or 15x power, depending on the type of microscope you use. Tube It is the part of a microscope that connects the eyepiece to the objective lenses. Arm The arm functions by supporting and connecting the tube to the base. Base It is the bottom part of the microscope used for support. Illuminator An illuminator is built into the base of the microscope. It provides even, high-intensity light at the place of the field aperture so light can travel through the condenser to the specimen. Stage with clips They hold the slides in place. If your microscope has a mechanical stage, the slide is controlled by turning two knobs. This means you do not have to move it manually. One knob moves the slide left and right, the other moves it forward and backward. Revolving nosepiece or Turret It holds two or more objective lenses and can be rotated to change power easily. Access to high-quality microscopic images online is accessible. But nothing beats the real experience when kids can see the magnified visual of small objects themselves. This is what a microscope has to offer—it can greatly strengthen your child's academic experience. This is especially important for students who are interested in the field of science. But even those who do not want a science career may also need access to it. For one, microscopes make science hands-on for everyone. This tool helps them understand the methods that scientists and doctors use to study the environment and world. Indeed, microscopes have become fundamental for studying biology, particularly in looking at cells. If your little one is in late primary or high school, they will most likely need a microscope set with at least 400x magnification. There are many affordable options on the market with this magnification or higher at a reasonable price! Take a look at this Discovery Microscope Starter Set - Heebie Jeebies (MS1015). For only $59.95, you can provide your kid with the perfect microscope starter kit. This microscope set includes a stylish microscope, 5 prepared slides, 5 blank slides, plus slide covers and labels. Plus, it comes with accessories like a petri dish, eosin dye, tweezers, plastic scalpel, and more! Most importantly, it has 100×, 400×, and 1200× magnification. So, what features should you look for when shopping for kids microscopes? Here are some important things you need to consider. 1. Type of microscope There are two types of kids microscopes on the market. Each is used to view different samples, and these are: Stereo microscopes (low power) Compound microscopes (high power) Stereo microscopes are used for viewing 3-D specimens, like a crystal, coin, or bird feathers. Also known as dissecting microscopes, this type of digital microscope is designed with a low magnification power. They provide anywhere from 10x-40x magnification. Kids stereo microscopes are available with three sorts of magnifications: Single magnification (20x is the recommended power) Dual magnification Zoom magnification They may also come with extra features, such as a large staging area for dissections. Compound microscopes, in contrast, are used to look at things you would not be able to see with the naked eye. This includes bacteria and blood cells. Thanks to its high magnification power, it provides a larger image or view of the object than stereo microscopes. For viewing of samples, slides and coverslips are needed. There are also compound microscopes that have a mechanical stage on them. This feature allows you to maneuver the slide a lot easier, especially when viewing at higher magnifications. 2. Magnification An important feature of a microscope is its magnification. It enables you to see how detailed the small object is. If you are shopping for your kid's microscope set, pick a unit with high enough magnification. As much as possible, opt for something sturdy but not too expensive. But how much is enough magnification for your child? This will depend on how small the items your kid will likely look at. 400x magnification will allow them to view and study cells. Tip: We recommend investing in a microscope with at least 400x magnification available and above. If you plan to get one with higher magnification, make sure the microscope has a strong light source. Or if it is a school requirement or specific curriculum, check what magnification is required before purchasing. 3. Source of electricity Will you go for cordless or not? All microscopes need a light source for more clear and detailed viewing. Microscopes that could work on batteries are especially crucial in many classrooms. For one, students could trip over cords when working throughout the room. But if the microscope set will be used at home, think of your child's at-home lab setup. Is there a nearby outlet for the device? Even so, it may be worthwhile to invest in one that can work without a cord. 4. Digital options A microscope set with digital features may provide more benefits to your kid. Depending on the setup you have at home or school, you may be interested in digital options. There are units you can plug into a computer, while some have a camera hookup. The latter would work well for a homeschool setup. For instance, the instructor can use the digital hookup for demonstrations. So, is it necessary to buy a microscope for kids? The answer is yes! Studying the structure of tiny objects that cannot be seen with the human eye alone could be something that your child is interested in. Regardless, a microscope makes the perfect learning companion for them! Where to buy microscope kits? Here at Wiltronics, we offer a wide range of microscopes suitable for kids, students, and education and laboratory use.
Uses of Drones Today: What Are Drones For?
September 29, 2021
The uses of drones today range from military operations to aerial surveillance to simple recreation. They can carry out an impressive variety of tasks! Have you seen camera-wielding machines hovering in the sky? Most commonly known as drones, they are rapidly growing in popularity. What was once seen as vehicles used only by the military are now widely used across the globe, for industries and personal use. But what are they—this drone technology, and what they are used for? Let us find out the answers here! Over the past few years, drones have proven to be extremely beneficial in places where humans cannot and should not go. They also come in handy for those who are unable to perform a task in a timely and efficient manner. From military bases, search and rescue efforts, to your front door—drones can help make monotonous or dangerous tasks more efficient. The adoption of drone technology around the world also offers: Increased work efficiency and productivity Decreased workload and production costs Improved accuracy Refined service and customer relations Resolved security issues These are the biggest reasons why drones are being adopted worldwide. Not only for military use, but also for commercial and personal technology. Drones are unpiloted aircraft that are navigated using a GPS tracking system from the ground. They operate with different levels of autonomy through a software-controlled flight plan. In short, they are remotely controlled—thus, these robotic drones can fly unaided. Drones are also referred to as Unmanned Aerial Vehicles (UAVs), particularly when used for military purposes. They can be as large as an aeroplane or as small as the palm of your hand. These unmanned aircraft systems have the potential of reaching the most remote areas with no manpower needed. They carry out tasks ranging from the mundane to life-threatening. UAVs can be found flying around by land, sea or air for: Aerial photography for journalism and film Security purposes (e.g. building safety inspections) Express shipping and delivery Rescuing victims from disasters (e.g. hurricanes) Scanning an unreachable military base Advancing scientific research in extreme climates on the planet ...to name a few! This flying technology has increased in popularity with new models and types releasing over time. An unmanned aerial vehicle system has two parts: the drone itself and the control system. The nose is where all the sensors and navigational systems are present. Then the rest of the body is packed with UAV technology. As for the operating system, a drone's autonomy level relies on sensors to calculate its movement. This means it can be flown at varying distances and heights. Hence why drones make a few of the best candidates for taking the toughest jobs in the world. Different models are capable of travelling varying heights and distances. A typical drone with a close-range can travel up to three miles and a range of around 30 miles. This is mostly used by hobbyists. In contrast, short-range ones travel up to 90 miles and are primarily used for surveillance tasks. For scientific and meteorological research, they use mid-range UAVs with 400 miles distance range. The longest-range drones are called "endurance" UAVs. They have the power to go beyond the 400-mile range and up to 3,000 feet in the air. Types and sizes Drones come in a wide variety of sizes. As mentioned, the larger sizes are mostly used for the military. The next in size are the ones used for geographical surveying or to combat wildlife poaching. This type of unmanned aircraft usually have fixed wings and require short runways. Then there are mini flying robots that have made their way into our homes and serve as entertainment. These are the common drones we see hovering in the sky and controlled by hobbyists, photographers, and even kids! VTOL stands for Vertical Take-off and Landing. This type of flying has the ability to take off, hover and land in a vertical position, as the name suggests. Many drones, particularly multi-rotor ones, are considered VTOL. Also known as the Global Navigation Satellite System, GNSS can operate in both non-satellite and satellite modes. It provides enhanced connectivity during operation. GNSS allows Return to Home safety technology to function on a drone. You can also activate it through the ground station's remote controller. High-end GNSS systems use Satellite Constellation technology. This tech is a group of satellites working together to give coordinated scope. They are also synchronised so they can overlap well in coverage. Highly accurate drone navigation is very important when flying. This is especially true in drone applications such as creating 3D maps, surveying landscapes and search & rescue missions. There are three common types of drones with wide applications. Single rotor helicopters This type of drone resembles a helicopter but in a mini version. It can be gas or electric-powered. The single blade and ability to run on gas helps its stability and to fly for longer distances. Single rotor helicopters are used for transporting heavier objects. They can also be used to survey land, research storms and map erosion. Multi-rotor drones Multi-rotor is one of the smallest and lightest drones available on the market. This type of UAV has limited distance, speed and height. Multi-rotor drones can spend 20-30 minutes in the air while carrying a lightweight payload like a camera. They are ideal for enthusiasts and aerial photographers. But other units already come with a camera. Have a look at this RC drone (JGT4146). Ideal for hobbyists, this drone lets you stream your flight using the onboard 720p camera. Use your phone for live streaming; attach it to the universal phone cradle and get ready for take-off! This beginner-friendly UAV has built-in take-off, landing and Return to Home functions which allows you to operate it safely and conveniently. It makes the perfect present even for kids ages 14 above! You can fly it up to 60 metres away while connected to WiFi. As for the features, it has a 6-axis gyro and an onboard micro SD card. This means the amazing aerial views you filmed can be download and viewed later. You can fold the rotor arms away after flight, allowing for easy storage. Be sure to check the relevant regulations for use of drones and recording equipment. Fixed-wing drones As the name suggests, this type of UAV has fixed wings and is almost identical to normal airplanes. The wings provide the lift instead of the rotor, making them more efficient. Fixed-wing drones use fuel instead of electricity. This enables them to glide in the air for more than 16 hours. Considering their larger size and design, they need to take off and land on runways. These types of UAVs are usually used by the military, scientists, and for delivering food and goods to areas that are hard to reach. 1. Military The most well-known and controversial use of drones is in the military. Today's drones are much more advanced and can be equipped with thermal imaging, laser range finders, and even tools for airstrikes. On a positive note, there is also research into the usage of drones for the detection of IEDs and other explosives. They are also already being used for the mapping of landmines, helping to provide safer mine clearance. 2. Delivery There are drone models that are designed for transporting food, packages and other goods. They are referred to as last-mile delivery drones. They are used to make deliveries from stores right to your front doorstep. Delivery drones can carry 55 pounds of goods to your front door. They can make your life, and the work of retailers and grocery chains, more effective and convenient. 3. SAR (Search & Rescue) There are instances where first responders cannot go into a rescue situation due to the severity of the disaster. This is where drones come into play. For instance, if there is an avalanche, emergency rescue drones are deployed to look for those caught in the snow. There are also models that have been used to assist in fighting fires. 4. Photography Drones have been an excellent companion for photographers and cinematographers. Both beginners and professionals alike use UAVs for taking expansive aerial photos. This can be the secret to getting a bird's eye view of a city, beach, or a certain building. There are drones specifically for photography as well. They provide a new way to capture places from the air. But in places or buildings with obstacles, you might want to consider a UAV that is great for obstacle avoidance. 5. Wildlife and historical conservation Tracking wildlife populations is nearly impossible with humans on the ground. An effective solution for this is by using drones. They are cheaper and more efficient alternatives for wildlife conservation. Drones enable the keepers and specialists to see and track roaming group of animals with a bird's eye view. Moreover, they are also used for reforestation, such as scouring the forest floors affected by fires. These UAVs drop seeds, fertilisers, and nutrients that will help a tree rise from the ashes. 6. Agriculture Drones have also been beneficial to the agriculture industry. They especially come in handy and advantageous for farmers in several ways, such as: Optimising the farm Maximising efficiency Reducing physical strain UAVs can help them carry out field surveys, seeding, tracking livestock, and estimating crop yield. In short, drones can help agriculture professionals save valuable time. 7. Medicine Getting medical supplies to people in hard-to-reach areas can be tricky. Time is crucial too for delivering organs for transplant patients; traffic - be it land and air can be an obstacle for this task. But thanks to drones, this advanced flying technology can be the perfect solution! Modern UAVs are, in fact, being used for delivering emergency medical supplies and cargo to off-grid communities in Alaska. Plus, for delivering donated organs to transplant patients, as well! Did you know that one hospital in Maryland made history by transporting a kidney through a specially-made drone in less than five minutes? This shows how drones can help cut time down while offering a safer and secure method of organ and medical supplies transportation. 8. Outer space NASA and the U.S. Air Force have been testing out drones geared towards space travel. The X-37B UAV resembles the look of a space shuttle but in miniature size. This unmanned, reusable spacecraft by the US Space Force has been circling the Earth for the last two years. It set the record for longest flight from an unmanned aircraft. Basically, the X-37B UAV operates experiments for examination on Earth. It seems that drones have potential for future space exploration and innovation. 9. Recreation Lastly, drones can also be great fun! For instance, check out this Laser Battle Gun and Drone Set (JGT4082). Toss the drone into the air where it will hover automatically. Three successful hits with the infrared light beam to win and the drone will safely descend to the ground. As modern technologies continue to grow and evolve, drones will become more dependable. They will provide more new opportunities in military, transport, logistics, and commercial sectors. Hobbyists, photographers, and professional aerial cinematographers would also benefit from drone technology. Plus, the uses of drones today could expand in many categories in the near future!
