Light bulbs mimic daylight & night light for better sleep – Lighting Science

Who couldn’t use a few more hours (or even minutes) of extra sleep, or better sleep overall? We should all go to bed earlier, but sometimes that’s not realistic.  Couple our poor bedtime habits with the fact many of us are glued to our screens (being bombarded with blue light that stimulates the brain and disrupts sleep) and we’re not doing ourselves any favours.

There are ways to fight off these sleep disruptors; one of them is to change your light bulbs. Yes, by matching your body’s natural circadian rhythms to different colours of light, you can help you body stay properly in sync, and possibly even stay healthier.

I recently received samples of several lights from the company Lighting Science.  These lights are specifically created to compensate for the problems that the wrong lighting can create. Continue reading “Light bulbs mimic daylight & night light for better sleep – Lighting Science”

How to Reset Your WeMo, LIFX, Philips, Osram/Lightify Light Bulbs

I ran into a wee problem with one of my WeMo LED smart light bulbs.  It was easily cleared up with a reset, but it took me some surfing to find out how to do it.

That got me thinking, you might someday need to know how to do this yourself, and possibly for other bulbs.  So here’s a few smart light bulbs and how to reset them, with instructions from each manufacturer’s website.

How to Clean Sterling Silver if yours is Turning Grey, White, Black!

There’s nothing worse then pulling a cherished piece of silver jewelry out and finding it’s turned black, grey, white or yellow.  Trying to figure out how to clean silver it  can be tough.That colour is called tarnish and it’s the bane of any silver-lover.

I love making sterling silver jewelry in my spare time. Occasionally I take on custom-made jewelry requests. But I recently had a customer write me to say a necklace I’d made for him had turned black after just a couple weeks.  He was surprised and thought something was wrong with the piece. Though it can look unsightly if not cared for properly, tarnish is a normal and natural process with sterling silver. But once tarnish or blackening is there, how can you clean silver?

What causes Tarnish?

When silver tarnishes, it’s a surface discolouration  caused by the interaction of oxygen (air) with the silver. As the British Assay Office explains it, “silver naturally interacts with oxygen and sulphur-bearing pollutants to create silver sulphide, resulting in a visible discoloration of the metal’s surface. Silver tarnishes in environments containing various sulphuric gases, even in very low concentration. The amount of tarnishing is determined by the relative humidity, ambient temperature, gas concentration, and the length of time the silver is exposed to the gases.”

With sterling silver this process is normal, natural, expected, and yes, it can occur relatively quickly.

Many things can speed tarnish; air pollution, the minerals in your water (and as such, wearing your silver jewelry in the shower can speed this process too), living or working near a chemical, electric or manufacturing plant, or even in proximity to a gas starion are all things that can cause discolouration more quickly.

Recent studies have shown tarnish develops microscopically within hours of being cleaned and exposed to air again.  You may not see it on the piece for several days or weeks, but it’s there, and will show up as a black residue on a polishing cloth.

How to clean silver

A great way to keep seldom worn jewelry clean (and silverware if you have it), is to store sterling silver in a ziplock bag with all the air squeezed or rolled out of it.  You can wrap it in a soft cloth first too.  Oxygen and thus tarnish may still seep in and can still cause blackening especially if the pieces are stores for long periods of time, but it should keep things to a minimum. Another great way to keep jewelry tarnish free?  Wear it!  Constant contact with the silver keeps tarnish from building up.

Chemicals can cause tarnish

Chemically tarnished rings. Oops!Coincidentally at the same time as this customer contacted me,  I had a friend show me some rings I’d made for her.  The shiny sterling silver had turned a deep, dark black (photo at left).  This was no tarnish effect, and she admitted she’d immersed her baubles in some household cleaner (Lysol) to spruce them up.  Instead, they’d become instantly and deeply chemically oxidized.

Now, she actually liked this look and referred to it as ‘edgy’, so she’s leaving them as they are for now.  If she did want them restored it should be a relatively simple process of buffing the chemical scarring off the surface layer, and exposing clean shiny silver beneath.

Don’t experiment with cleaning silver using household cleaners!

But this also serves as a leaning moment; only soap and water, silver polish, or a silver polishing cloth should be used to clean your silver jewelry.  Many household cleaners and chemicals can alter your precious silver.  In fact, I once had a ring turn bronze after accidentally spritzing window cleaner on it, and had other silver turn grey by getting baking soda onto it.  That too buffed out, but you’ll want to be careful with your jewelry.  Chemicals can also permanently damage certain stones like topaz, opal and more, so don’t experiment; you run the risk of really doing permanent damage.

If you do find some discolouration of your silver, you can remove it with a silver cloth (brand names include Sunshine Cloth, which is available inexpensively from me,  HERE or HERE). If that won’t work, stop while you’re ahead and take it to a pro for professional help.

A Note about Grocery Store Silver Cleanser

I’ve purchased cleansers from grocery stores that just don’t work.  If you’re going to get a cleanser from somewhere other than a jewelry professional, test it first on a small area.  If the cleaner doesn’t remove tarnish instantly, it’s not working.  Proper liquid silver cleaners will remove all tarnish in about 3 seconds.  Fresh new polishing cloths.If you need to soak, or scrub, stop using it, rinse your silver, and return the cleaner to where you bought it and get your money back. (Keep your receipt!)

Jewelry Fix: What to do if Your Sterling Silver is Turning Black, Grey, White!

Why is my silver jewelry turning strange colours? It’s a question I get asked a lot. I recently had a customer complain about a necklace “tarnishing” just a few weeks after purchase. His wife decided to use the polishing cloth to give the sterling silver a wipe, and was aghast when it came away black.

So he wrote me to express his surprise that his new necklace would discolour so quickly.  It made me realize it’s probably a great education opportunity.

As the British Assay Office explains it, “silver naturally interacts with oxygen and sulphur-bearing pollutants to create silver sulphide, resulting in a visible discoloration of the metal’s surface.

A 3D printer, a drone simulator, and gadgets galore: Where to find them in Calgary

IMG_6278
Want to see what it’s like flying a high-end drone? There’s a simulator for that!

I was hunting all over my house for my power cord — my one lonely, last Apple power cable— and realized I’d left it at work.  My phone was about to die, and I figured it was well past time for me to get a second cable.  I was dreading having to go to the mall and fight summer vacation traffic, so I googled “Apple retailer” to see if there was a better way to get that cord.

When London Drugs came up I felt a bit dumb, “oh RIGHT! I thought, “London Drugs has a huge electronics department,” but I didn’t realize they also carried Apple products.

I grew up in Ontario but lived in BC for many years, and out on the coast, London Drugs is people’s main source for electronics, cameras, computers and gadgets.

It sounds weird that a “drug” store should be the go-to destination for tech gear.  Maybe it is, but that doesn’t change the fact that London Drugs carries just about anything you could want that uses power or batteries.

That got me thinking about London Drugs, so I got in touch with Assistant Store Manager Dan Do to see about getting the 411 on the store people might not have at the top of their minds.

Computers, Electronics, and yes, drugs
Dan gave me a tour of the Royal Oak store in northwest Calgary.  It’s kind of the opposite of a traditional electronics store.  It’s warmer and brighter for starters.  And yes, there’s also a huge part of the store devoted to the eponymous ‘drugs’, health and beauty, and household goods.
Living in BC, and something I’d totally forgotten, was the handiness of being able to pop in to London Drugs, pick up some specialty batteries, a camera peripheral or whatever, then grab a few things from the drug store.  It’s one stop and two items checked off my to-do list.IMG_6311

But back to the computer and electronics department. The day I was there, there were lots of staff on the floor.  Anyone looking blankly at the cameras, or the Fitbits for instance, had a friendly employee swoop in and ask if they needed help.

The Fitbits were one of the things that first caught my eye when I walked in, as part of a display with the Aria scale.  The whole line was there for people to look at, touch and get to know. Indeed, London Drugs has a lot of other wearables available too.

Drone Simulator in-Store
Speaking of displays, Dan led me over to a really cool set up that has to be a huge draw.  There’s a drone flight simulator right inside the store!  As part of the promotional set up for the ultra high end Solo drone by 3DR, there’s a controller right next to one of the drones.  You can test it out and see how easy it is to fly (if you let go of the controls, it doesn’t crash, it hovers!).  Test flight over New York’s Statue of Liberty?  Yes, please! The Solo is built to work with GoPro cameras, something else you can pick up at London Drugs.

3D Printers?  They’re HERE

The Tiertime Up Mini 3D printer spit out this tiny dinosaur model.
The Tiertime Up Mini 3D printer spit out this tiny dinosaur model. You can buy this printer on the spot if the demo wows you.

If you want to get wowed some more, the London Drugs store I visited in Royal Oak also has a functioning 3D printer.  Yes, that technology you’ve been hearing about on the news is actually available at your corner London Drugs store.
The Tiertime Up Mini works just like a regular home printer, except with the obvious distinction of printing objects in 3D.  While the store model is for demonstrations, the printers are in stock, so if you want one, you can probably take one home on the spot.

While we’re on the subject of printers, London Drugs has a full selection.  Printers are so inexpensive now, it’s shocking.  The store also had a large scale Epson Surecolour art-quality printer for sale, which is a perfect back to school must-have for an art or photography student, or an amateur photographer. (Not to mention, the photo lab in the back can also do professional photo processing and printing and can print up to 44” prints in house! Plus there’s often free shipping. But I digress.)

While I was looking over all the amazing electronics and computer equipment at London Drugs, Dan reminded me they’re a Canadian company.  I really love dealing with Canadian companies.  It’s probably some sort of underlying patriotism, but it’s nice to know, and makes me feel good about spending my money here. That’s when I also found out London Drugs must be some kind of great employer, because one of the employees I talked to on my tour had worked at the store for 12 years, and one had been there 30 years, and apparently that kind of long-term service is common! Something else I didn’t know? London Drugs has been in Alberta for 30 years.

IMG_6317Back on the tour, I got a look at the computers and tablets all on display and ready to play with.  From the Microsoft Surface Pro 3 to Apple’s iPad line, and even London Drugs own computer brand, Certified Data, there’s a whole host of computers to pick from. Plus, if you ever need serious help with your computer, there’s an emergency service centre right in all stores.  That means you can bring your computer or tablet in and get it triaged, and fixed, all right on site in many cases. There are even Apple certified technicians in-store, meaning you can skip the Genius Bar, and the frenzy at the mall!

Skip the mall and your your Apple here
Speaking of Apple, I was really wowed at the full selection of Apple products at London Drugs. I’m a full-on Apple girl, so being able to pop into London Drugs to service my MacBook, or pick up Apple-authorized cords, cables or screen protectors or cases for my iPad is super convenient. (Because let’s be honest, those cables you buy from the internet will stop functioning with your Apple products after a few months and you’ll need new ones anyway. Take my advice and just buy the real thing.  It’s more expensive, yes, but you’ll have it for the life of the product.)

Back to my cable conundrum.  I finally decided to place my order on line and pick up in store later that day, another great London Drugs option that means you won’t need to waste a trip to a store only to find they’re fresh out of what you need.

So now London Drugs is top of mind for me again when it comes to electronics, computers and gadgets. And I can thank them for the power I needed (and the inspiration) to write up today’s blog, right from my fully re-powered phone!
