With the packed schedules and truly demanding routines of modern life, a little break from the hustle and bustle is necessary every once in a while. Sure, we all have deadlines to meet and places to be, but when you need a change of pace, the great outdoors provides the perfect opportunity. Not only are the views and sounds of nature refreshing, but the activities that come along with them are just as exciting.

The living room is one of the most important rooms in the house, and an entertaining area of this kind won't be complete or functional without a TV. While some people overlook the addition of a television set because it can be addicting, having one can help you stay up-to-date with everything that's happening in the country and the world.

Insulation has an important role in electrical systems, from basic wires and cables to more complex and high-power components, such as industrial machinery, motors, and transformers. It is tasked with resisting current and keeping it on its designated path through the metal conductor. In simple terms, it prevents electricity from leaking, while also shielding conductors from environmental factors, such as water and heat. 
Damage to insulation can lead to a variety of unwanted issues, from dim or flickering lights, damage to expensive appliances and machines, or electrical faults, such as short circuits or electrical fires. But the main reason you'd want insulation in top condition is to minimise the risk of electrocution and burns. 
Assessing the quality of the insulation in cables, appliances, installation, machinery, and more is done with thorough testing using a resistance tester. This passes a defined voltage through the insulation to measure the resistance. Higher values, usually in mega or gigaohms, indicate that it is in good condition and won't pose safety risks. Lower values, often point to insulation that is fraying, cracked, or more severely damaged and something that can mean expensive repair costs or serious injury.

If you have a soft spot for arts and crafts and DIY projects, you know that nothing compares to the feeling of creating something with your own two hands. Painting, sculpting, mending and other similar activities are fantastic ways to de-stress and relax. Not only...

Smartphones have all but killed off compact 'point-and-shoot' cameras. But they’ve yet to come close to the control and adjustability that current mirrorless and DSLR cameras provide. Not to mention picture quality. Bigger sensors definitely help in this respect, but so do optics. This, and an understanding of how light and colour determine the outcome once you press the shutter button.

Lighting is a concept that many beginners seem to struggle with, particularly artificial lighting used in studio portrait and product photography. The move from natural outdoor lighting to lighting in a controlled setting, however, opens up many possibilities. This is the same transition from Automatic camera settings, to control motion, depth-of-field, and light with the camera (or lens) set to Aperture or Shutter Speed Modes.

RCD and appliance testers that have RCD trip features work by simulating current leakage in order to accurately measure the amount of time needed for the appliance or RCD to cut power. The trip time recorded by the tester determines whether the appliance or RCD meets the AS/NZS3760:2010 requirements, which demand the RCD or appliance's trip time is as low as 40 milliseconds. The most frequently used RCD tests require a trip time test at the rated current of the RCD itself. The fault current needs to be quickly applied by the tester. In most cases, the RCD is sensitive to 30mA, even though in some applications, like medical institutions, 10mA sensitive RCDs may be used. In other cases, variable trip current RCDs are used.

A person doesn’t have to be a first responder, an outdoorsman, or even a plumber to appreciate just important - or how ubiquitous - having a reliable flashlight is.

Whether it’s a 300 lumen knapsack essential that fits in the palm of your hand, or a 25,000 lumen torch that's kept as part of your family’s emergency preparedness kit, as a minimum, a flashlight can make finding your keys in the dark less of a headache. Or it can illuminate the way to safety in near-zero visibility.

Most flashlights, however, fall soundly between these two extremes. These are the modern, high-intensity lighting devices that are compact enough to qualify as everyday carry items, but robust enough to count on in case of a genuine emergency.

Did you know that about 10% of the Australian daily water supply is lost through leaks? And it doesn’t seem like it’s coming to a halt anytime soon either. In fact, water damage claims have virtually doubled down on the number of fire and break-in complaints in recent years. They’re normally caused by a faulty pipe system, changes in water pressure or high temperatures, all of which may lead to extensive damage in your household.

Minelab has been in business for a long time and is a well-known brand among treasure hunters. Ron Shore began selling metal detectors from his Chicago basement in 1985. Like any new business, he went through many trials before developing his detectors to be exactly what the gold enthusiasts needed and wanted.
