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.

Thinking about buying a refurbished Samsung? Refurbished phones are undoubtedly one of the easiest ways to get a high-end phone without investing a small fortune in it. However, a lot of people are opposed to purchasing a refurbished second-hand device, as there’s almost never a guarantee that you’re getting a phone that is 100% functional.

Different types of welding, different equipment. But common to all of them is the welder rod or electrode. This is the metallic rod or wire that is used to create the bond between two metals. There are dozens of types of electrodes, each used with specific metals and in different welding types. Knowing which to choose will also determine the overall strength and finish of the weld.
