PURE WATER

Getting pure water is a bear. I’ve tried everything. Recently, a company sent me a new reverse osmosis system that sits in a small space on my counter. It’s called “Aquibear.” Before Aquibear, I tried water pitchers with replaceable filters, such as Brita and ZeroWater. My new condo has an LG refrigerator with a filter built in. But none of these things were as good as Aquibear is so far. I know because I tested them. I bought a $15 “HoneForest” water-quality testing stick on Amazon. All I had to do was put the stick in each glass of water I tested and check the digital read-out. A high score means lots of pesticides, parasites, arsenic, lead, microplastics, virus nitrates, […]

I LEARN TO FLY A MINI DRONE

DJI makes the best drones, according to just about everyone. But who wants to spend a thousand dollars? I don’t know about you, but I’m not planning to become a drone professional. Recently, I borrowed a $31 Holy Stone “HS 210” mini-drone from a friend. It’s astonishingly easy to fly, compared to the last miniature drone I flew. The old quadcopter shot past me like a rocket, banging against every obstacle in my apartment. Not this time. Push a button on the three-inch-by-three-inch flying machine and it launches. Push another and it flies in circles. Push another and it does aerial flips, or lands. Push two buttons —  if it’s about to hit Aunt Sally — and it shuts off […]

NON-FUNGIBLE IS ALL THE RAGE

Did you hear about the New York Times article, still online, that sold for $560,000? How about the digital cat in a pop tart? It sold for $590,000. Or the 5,000 online images that sold for $69 million? They’re part of the brave new world of “Non-Fungible Tokens.”  “Non-fungible” means “can’t be copied, unique,” much like the items on Antiques Roadshow. In the digital world, Non-Fungible Tokens (NFTs) are sold in online auctions. If you buy a token, you own a link to a unique piece of digital art, music, video clip or what-have-you. Recently, a video clip of  LeBron James’s basketball dunk was tokenized. The buyer paid over $200,000. Before NFTs, digital files weren’t considered unique because they’re so […]

SMARTER EYES

My mom used to swear by eye exercises. She said they would correct nearsightedness. Science may be proving her right. Kubota smart glasses can fix your eyesight, if you wear them 60 to 90 minutes a day, according to a report in ZME Science. They work by shortening the distance from the cornea to the retina using augmented reality and virtual reality. Fortunately, you don’t have to wear them for hours at a stretch. They’re a bit odd-looking. At a distance, the lenses look like windshields after rocks have shot through them. The smart glasses were developed by Kubota Pharmaceutical Holdings of Japan. In Japan, 95 percent of those under age 20 are myopic. In South Korea, it’s 96 percent, […]

LOOK MA, NO GLASSES PRESCRIPTION

I asked a friend to be a guinea pig for the “EyeQue,” a $60 gadget that tests your eyesight and gives you a prescription.  Results were great for him, not so for me — but that wasn’t the machine’s fault. Besides giving you a prescription, EyeQue will send you a pair of John Lennon-style glasses for an additional $19. They call them “try-ons.” They work well and look fine, but you’ll probably want another pair. For instance, the bridge width and earpiece length may be slightly off, since EyeQue doesn’t ask for these measurements, which are typically found on your old pair of glasses. My friend ordered new frames from GlassesUSA, which is not affiliated with EyeQue. He now sees […]

A SECOND LOOK AT AMAZON HALO WEARABLE

Amazon Halo, the new Fitbit-type wearable I wrote about it last time, is even weirder than I thought. But I like it.  Halo’s voice analysis can pinpoint my moods to the very second, telling me when I sound delighted, amused, shy, and so on. (I’ve yet to sound angry even once in over three weeks.) For example, it said I was  “miserable” at 11:10 a.m., but “happy” exactly two seconds later. If you want to improve your tone, the app has video challenges for that. For instance, a four-time martial arts champion and yoga expert guides you in warm-ups for powerful public speaking. You can turn off the mike if you don’t want your tone analyzed. Speech samples are processed […]

BUILD YOUR OWN

We remember when personal computers first came out. You could build them yourself if you were savvy. That’s what Michael Dell did way back when. He sold them to other college students and the business went on from there. Now there’s a computer that kids can put together. The “Computer Kit Touch” is $280 from Kano.me. Designed for young children, it has a ten-inch screen. Follow a printed storybook to build a portable, touchscreen computer, and attach a keyboard. From there, kids can make apps, art, and games with simple steps. Included apps are Chromium (a web browser similar to Chrome), YouTube, Libre Office (similar to Microsoft Office) and Google Drive; more are available in the app store, such as […]

THE BIG DISCOUNT

So we went to the drugstore to pick up Bob’s post heart-attack prescriptions and the pharmacy clerk said she looked around and knocked $135 off the price. That cut the bill in half. She should go on our Christmas list. What she did was look at our prescription list and then went to her phone to check that against an app called “Good RX.” This must be pretty new stuff because we just heard of it last week. We heard of it but we’re not as sharp as the gal at the pharmacy and we didn’t install it on our phone. We thought: come on, how much could this save you? Good RX gives you coupons for lots of pharmacies, […]

HERE THERE BE TYGERS AND ALL MANNER OF STRANGE BEASTS

One of our frequent correspondents had a near miss. That’s a near miss from disaster when he got a phone call telling him his PayPal account had been compromised and he owed $340. The caller said they could fix the problem for $299 but they needed to take control of his computer. They said they needed his bank account number too, so he gave it to them. There was a lot of background chatter on the caller’s end of the line. The red flags went up, the rockets exploded and the bells started ringing. He turned off his computer, told the caller he just had a power outage, hung up and moved everything from his checking account to his savings […]

HOW BOUT FREE PHONE SERVICE?

A reader latched onto his wife’s old Samsung Galaxy phone, now that she has a new one. At first he thought he needed a cheap phone service to go with it. We suggested a Tracfone plan for $7 a month — $21 every 90 days for 60 minutes of talk time. But he decided to go even cheaper: use free Wi-Fi to make calls. If you use Google Voice, Google Hangouts, Skype or some similar service to make calls, you don’t need a dedicated phone service. Search on “How to Make Phone Calls and Texts from your Smart Phone without Cell Service,” which leads to full instructions at HowToGeek.com. (Gotta love that name.) But what about the landline? You know, […]
