Exoskeleton Aims to Prevent Falls for Seniors

Posted on by

When we think of exoskeletons, we tend to think along comic book lines: mechanical suits bestowing superhero strength upon the villain. But perhaps more practical uses for exoskeletons exists: restoring the ability to walk, for instance, or as in the case of these exoskeleton shorts, preventing hip fractures by detecting and correcting falls before they happen.

Falls and the debilitating injuries that can result are a cruel fact of life for the elderly, and anything that can potentially mitigate them could be a huge boon to public health. Falls often boil down to loss of balance from slipping, whether it …read more

We’ve Got It Down PAT: Appliance Electrical Safety Testing

Posted on by

Everywhere we look in our everyday lives, from our bench to our bedroom, there are the ubiquitous electrical cords of mains-powered appliances. We don’t give our electrical devices a second thought, but in addition to their primary purpose they all perform the function of keeping us safe from the dangerous mains voltages delivered from our wall sockets.

Of course, we’ve all had appliances that have become damaged. How often have you seen a plug held together with electrical tape, or a cord with some of its outer sheath missing? It’s something that we shouldn’t do, but it’s likely many readers …read more

Don’t Try This at Home is Cliché for a Reason

Posted on by

Oh, for cryin’ out loud. That’s the last straw. We’ve seen one dangerous YouTube video too many. Are we honestly cursed with a false feedback system that unequitably rewards dangerous behavior in online videos? Obviously the answer is ‘yes’. Now the real question becomes, can we do anything about it?

The Shocking Truth About Transformerless Power Supplies

Posted on by

Transformerless power supplies are showing up a lot here on Hackaday, especially in inexpensive products where the cost of a transformer would add significantly to the BOM. But transformerless power supplies are a double-edged sword. That title? Not clickbait. Poking around in a transformerless-powered device can turn your oscilloscope into a smoking pile or get you electrocuted if you don’t understand them and take proper safety precautions.

But this isn’t a scare piece. Transformerless designs are great in their proper place, and you’re probably going to encounter one someday because they’re in everything from LED lightbulbs to IoT WiFi switches. …read more

The Importance of Electrical Safety

Posted on by

Everything you do bears some risk of getting you hurt or killed. That’s just the way life is. Some people drown in the bath, and others get kilovolt AC across their heart. Knowing the dangers — how drastic and how likely the are — is the first step toward mitigating them. (We’re not saying that you shouldn’t bathe or play with high voltages.)

This third chapter of an e-book on electronics is a good read. It goes through the physiology of getting shocked (DC is more likely to freeze your muscles, but AC is more likely to fibrillate your heart) …read more
