Action Camera Accessories You Should Get for Your Next Adventure

Let’s face it: traveling—whether it’s a leisurely visit to another country or an action-packed mountain trek—affords A LOT of photographic opportunities for your Instagram feed. But while phone photography might suffice for casual travelers, more adventurous types might need something more.

Enter the action camera. These small-but-powerful cameras definitely bring a new dimension of photography for those who love adventure. Check out these action camera accessories that you definitely should bring with you on your next trip.

Tripod


A tripod is a must-have for travel photographers, especially those who love taking landscape and long- and multiple-exposure photos and videos. Tripods can also come in handy when you want to dabble in taking photos of the sky, especially at night when the stars are out. You might even capture the Milky Way on a clear night when you go hiking.

Tripods will also help you maximize your camera’s time lapse function (group photos, anyone?). Check out brands made out of aluminum for sturdiness; if you have more money to spare, you can invest on carbon fiber models.

Monopod

The selfie stick is not just for selfies. The monopod comes in handy when you’re planning to use your action camera all day. Bloggers can also use a monopod for quick interviews, for example. This humble accessory can also help you take steadier, clearer 360 or panorama photos and videos. And of course, you can use it for the ubiquitous selfies for the “pics or it didn’t happen” social media uploads.

However, the selfie stick you’re using for your phones might not be robust enough for your action camera. Some mandatory features you should definitely include are hand grips, articulation angles, and extension length. There are even models that can charge your action camera on the fly.

You can also check if your action camera’s brand have proprietary monopods to make sure you don’t have compatibility concerns.

Helmet and Chest Mounts

Cyclists will benefit the most with helmet mounts for their action cameras, especially as they take photos and videos of their trails. However, helmet mounts are also valuable for hikers and mountain and/or rock climbers. Those who routinely explore caves can also document their adventures easily with the use of a helmet mount.

For more stability, chest mounts are also available and can give a different, more interesting perspective in your action shots. Water sports enthusiasts, like surfers and kite boarders, meanwhile, can look for water goggles or diving masks with camera mounts.

A side note: some brands also take pet lovers into mind, so if you take your furry friends with you during your adventures, a pet mount is a must-have.

Waterproof Cases

Most action cameras are already waterproof up to a certain depth, usually 10 meters. However, if you’re planning to take more deep-water photos and videos, a waterproof case will prove invaluable.

Most waterproof cases can handle depths of up to 60 meters (197 feet), which is the standard depth for most scuba diving adventures. You can also find specialized diving masks with attached camera mounts. The handier ones can DIY a basic mount onto their masks, though these might not be able to go too deep, especially with stronger currents.

Drones


Bring your action camera to new heights with aerial photos. Drone photography has been steadily gaining popularity through the years, and some truly breathtaking photos have already made their rounds in the internet and beyond.

Beginners can take advantage of ready-to-fly quadcopters, while more experienced users can look for BNF or bind-and-fly models. ARF or almost-ready-to-fly are best for the DIY enthusiasts or are looking for customizable options. Many drone models can already be controlled by mobile devices, though there are drones that need specific remotes.

On the other hand, some models may be more difficult to navigate than others, depending on the complexity of the internal computer installed, also called the flight controller. More expensive models have additional sensors that make them easier to control.

The next time you travel or go on an exciting outdoor adventure, make sure that your action camera is fully equipped to take on the challenge. Acquiring the right camera accessories will allow you take the most amazing shots you never even thought you could do.

What is a Thermocouple and Will it Keep my Drink Icy Cold?

What is a thermocouple?

It is an electrical device that consists of two different conductors forming electrical junctions at different temperatures. A temperature-dependent voltage is produced as a result of the thermoelectric effect, which can be recorded and measured to interpret temperature. The thermoelectric effect is sometimes referred to as the Seebeck or Peltier (or Seebeck-Peltier) effect, in credit to the physicists Thomas Johann Seebeck and Jean Charles Athanase Peltier who discovered it independently of each other.

Some of you may have read ‘thermoelectric effect’ and thought, aha, let’s make electricity! Indeed, taking the thermoelectric concept of heat to voltage conversion, a series of thermocouples connected together forms a thermopile. The more thermocouple pairs in series increases the magnitude of the voltage output. Otherwise known as a thermoelectric generator it has the advantage of producing electricity in virtually all conditions, providing there is a heat source.

In Gas Appliances

Many gas fed appliances around the home, such as boilers and ovens, use a pilot flame to ignite the main gas burner when required. A problem may occur if the pilot flame goes out and unburned gas is allowed to be released. Naturally, leaked gas is never good and poses the risk of an explosion or a health hazard. This is where the thermocouple comes in as a fail-safe component. Its tip is attached to the pilot flame, and so long as there is a thermoelectric effect, i.e. the pilot flame heat generates a voltage, the pilot gas valve is held open. Conversely, if the pilot flame goes out, the thermocouple temperature falls along with the voltage. This closes the valve and avoids any leaks. Similarly, they are used to shut off gas supply in the event the main burner does not ignite after a specific period of time.

Many newer appliances have made use of an electronically controlled ignition, avoiding the need (and associated risk) of a constant pilot flame. Whilst this is more fuel efficient, and certainly safer in that gas cannot be built up, it is dependant on an external source of electricity. This is what makes the simple thermocouple invaluable as it does not require any external excitation and can operate in the event of a power outage.

In space travel

It is exactly that self-sufficiency that makes thermocouples ideal for remote use with little external energy. Many space probes travelling far from a solar source (or a weak source in general) make use of a thermoelectric generator. The heat source used on the Mars Curiosity rover, for instance, generated electricity from the heat produced from the radioactive decay of transuranic elements.

In lamps and radios

Perhaps not as sophisticated as radioisotope thermoelectric generator but equally as important, kerosene lamps have been modified to operate batteryless radio receivers in isolated areas such as thick forest or mountain ranges. Similarly, some survival lanterns use the heat from a single candle to run several light-emitting diodes.

In drink coolers

Have you ever wondered quite how your drinks stay nice and cold on a baking hot day in the park? There is a thermocouple to thank for that. The thermopile draws heat away from the interior of the cooler using the Seebeck-Peltier effect. The heat from the thermopile is dissipated with a fan, leaving the interior of the box to cool by as much as 20 Degrees Celsius (68F). All that’s needed is a good thermal insulator around the box, and a steady supply of AC from your car’s lighter socket or mains.

thermoelectric generator that sits as a coaster for your drink. We’ll drink to that!

As fascinating as the thermoelectric effect may be, care must be taken when handling electronics. If you are not sure, comfortable or confident, research until you are! If you would like to experiment with thermocouples stick with trusted electronic suppliers, such as RS Components.

4 Important Benefits of Automated Material Handling

Ports, warehouses, and factories have long depended on machines to accomplish material handling for plenty of tasks. Particularly, this applies to both the manufacturing of products and the packaging and transporting finished ones. As a matter of fact, various types of equipment have, for a long time, been vital to tasks that require a lot of movement, distribution, and disposal of different types of materials.

What’s more, rapid developments in logistical and manufacturing requirements have resulted in different types of designs catering to different needs and budgets. For example, companies with lower budgets can still make do with manually-operated lifts, pulleys, and crane systems. Meanwhile, those with more specific needs can make use of more specialized systems that use information technologies and incorporate motors, linear stages, and actuators for more precise motion control. This gives business owners and managers more choices if they wish to embrace automation as a means to improve efficiency.

However, an automated material handling system’s benefits go beyond improving productivity. Here are just four important ways that automating material handling positively impacts your business:

1. Redundancies Are Avoided

With a proper system in place, a company can work more capably, even with a smaller crew. Automating the material handling process means that you can survive with a smaller team that’s focused on guaranteeing that your machines are doing their job properly. However, relying on automated equipment doesn’t just allow you to hire fewer workers to handle your materials or products. It also leaves you with more resources to have a smaller but more dedicated group to handle your materials with greater care and efficiency.

2. Time on Distribution Is Lessened

Upgrading to automated material handling systems means you get to take advantage of technologies like robotic arms, gantry systems, check-in machines, sorters, conveyors, and barcode (or RFID) scanners. These tools ensure that factory and warehouse crews don’t have to manually check lists when producing, moving, controlling, and storing materials. The result is that everyone works more efficiently and with fewer chances for human error to impact their work. This doesn’t just allow you to accept more orders or improve inventory management. It also lessens the need to have your crews work longer hours and cost your company in overtime pay.

3. Company-Wide Stress Is Reduced

By relying less on humans, you reduce inconsistencies in work quality due to a stressful working environment. After all, stressed and demoralized employees tend to bring down your production line’s overall performance. But since automation passes laborious and repetitive tasks to tireless machines, you can expect overall stress levels to drop among your employees. This results in fewer mistakes from everyone, which brings us to our final point.

4. Accidents Are Minimized

Material handling should never be taken lightly. After all, accidents are hard to avoid when working with machinery large volume of products on a daily basis. Thankfully, fulfilling the previous three factors greatly reduces the chances of unpredictable workplace accidents that can cause injuries or losses because of failed production processes. Indeed, fewer working hours, a less stressful working environment, and work consistency brought about by automation all minimize the risk of accidents derailing operations. What’s more, these also protect you against costly compensation lawsuits—further helping you save time and money.

Advances in task automation are now transforming production lines and storage and distribution services for the better. Regardless of the type of machines used, plenty of large-, medium- and small-scale machines are now capable of operating with little to no human interaction. Because reliability is improved and errors are reduced, operating costs are minimized across-the-board, allowing businesses to make more while putting in less.
