Rayovac discontinued their Hybrid NiMH

Years ago I decided to quit using Alkaline batteries and instead move to rechargeable. Of course, old nickle cadium (NiCd) batteries were horrible. They were prone to "memory" problems where a the recharging/discharging cycle could result in a loss of capacity. NiCDs also discharged quickly and just could not power some higher demand devices like today’s digital cameras.

I initially bought name brand but the Energizer NiMH were weak. Their D cell rechargeable batteries turned out to be spacers to fill the size of a D but with only a AA inside which I supposed doesn’t really matter except that "D cells are typically used in high current drain applications" [Source, Wikipedia, D battery] Duracell rechargeable batteries were equally disappointing. Now for years I chose Rayovac alkaline AA batteries for most applications and Energizer Max AAs for digital cameras. One day in Target, hidden toward the bottom of the batteries and off to the side, I found a package of generic looking rechargeable batteries labeled "Hybrid." I pleasantly discovered this was a Rayovac product and it rocked! In addition to being a great battery, Rayovac didn’t require a Rayovac charger.

Eventually Rayovac switched to a green label and then a blue label. It felt like the redheaded stepchild of rechargeable batteries but I loved the performance. Over time a cell or two died but I didn’t have the knowledge for using my multimeter to determine a good cell from bad. We just bought more batteries and soon our house had enough rechargeable batteries that we rarely use alkaline batteries anymore. Eventually I discovered the Ansmann 5207123 Energy 16 Charger. What an awesome investment! Even though NiMH don’t really get memories like the old NiCDs they do start to wear down. The Ansmann charger evaluates the cells and can refresh them. I quickly eliminated our bad cells and the charger worked to restore live to the remaining cells. On one it took 4 days but brought it back to life! Since the Ansmann is microchip controlled it does not require batteries being charged in pairs and since it conditions the batteries you can leave 12 AAs in it until they are needed. This makes it really easy for the children to use the batteries (unlike other charging systems).

So today I was reading a review of the new hotness, nickle zinc (NiZn) batteries. Despite the good words about PowerGenix’s Nickel Zinc AA I’m not ready to make the switch. Part of my hesitation is that NiZn requires a special charger and I don’t want the children accidentally putting a NiZn into the NiMH Ansmann charger; melting $114 device would make me sad. Another is that where an alkaline battery comes charged to 1.5V and most electronics are designed for 1V per cell, and a NiMH charges holds an optimal charge at 1.2V, the NiZn charges fully to 1.8 and holds an optimal charge at 1.6. I have not clearly answered the question of whether or not this poses a risk to certain equipment. I’m certain it doesn’t.

In the review, I discovered that Rayovac has discontinued their Hybrid AA/AAAs! Turns out, Hybrid is from 2007; it was rebranded to a blue wrapper in 2009 and is now (2010) called Rayovac Platinum Pre-Charged according to a review by the awesome NLee the Engineer.

We now use the Rayovac batteries in all the kids toys and our various electronic devices. For Cathy’s digital camera, we use Sanyo Eneloop which rates the same as the Rayovac Hybrids but had a distinctly different label that warns the children "do not use these." So, if you are looking for rechargeable batteries for the holidays, I recommend Rayovac Platinum Pre-Charged and Sanyo Eneloop.

Do your holiday shopping with Amazon!

This year we are striving to do most of our shopping online. I know it goes against "buy local" but if buy local means fighting crowds in a big chain store that isn’t locally owned then I’d rather shop in my pajamas through Amazon. I participate in Amazon’s affiliate program. When I refer people to Amazon, I get rewarded by Amazon. It does not raise the price of the person referred nor cost them in any way. So, if you are inclined to do your shopping online and do not participate in the affiliate program yourself, please consider getting to Amazon by using the link http://amazon.djuggler.net/ which simply goes to http://www.amazon.com/?linkCode=shr&camp=213733&creative=393193&tag=sidesigns-20. Much obliged!

The Internet’s Lowest Common Denominator

I have reduced the Internet!

To consume all knowledge on the Internet, you only need four sites:

That’s all you need! Granted, there are some sites that make the Internet a little more fun. Hundreds. For instance, Facebook has some value in that, "don’t make me think" kind of prime time comedy hour thing. Seesmic is a great aggregator for viewing your social networks in a single place. For getting links and news, the only aggregator ever needed (and this is huge geek crack so if you have no self-control stay away from it!) is Popurls. That’s about it. Sure, you should look in on Flickr once in a while but nothing else is really needed. Of course, there’s some utilitarian stuff like banking and travel sites but really…the Internet has come down to 4 sites. You’re welcome.

CRS disease related to 20-30 years of stress

Stress hurts memory. And my memory is undeniably in a less than adequate state. The memories are there. The recollection is poor. After feeding me a few clues, the memories surface. Clues can be reminding me of your name or where we last bumped into each other etc.

An experimental drug developed by researchers at the University of Edinburgh reverses age-related memory decline in mice, returning their brains to a more youthful state of cognitive function. The compound is designed to dampen the production of glucocorticoids, stress hormones that are thought to damage the brain’s learning and memory centers over time. [Source, Technology Review, Experimental Drug Preserves Memory in Rodents]

"What’s most surprising is that even short-term inhibition was able to reverse memory loss in old mice. I don’t think people had realized this was so reversible. It takes [the animals] back to being relatively young." Sign me up! I hereby declare my readiness to be a human subject in this testing of this drug!

Kindle – Killing paper books forever

I’ve declared for some time now that we are in the midst of a revolution and no one realizes it. That revolution is the death of books. Much like CDs replaced LP records in the early 80s, we will look back at this time and say that in the 2010s electronic books replaced paper books. Paper books will become the thing of collectors. It will take 20 years to realize this as the Kindle and the Apple iPad work their way into schools. Once we get one generation of children through the school system primarily reading text books on e-readers instead of paper, traditional books will die.

I was going to buy a Kindle at the beginning of the week but Amazon was conveniently "temporarily out of stock." I did not realize this meant that Amazon was releasing a new Kindle at only $139! They also improved the contrast on their $189 model (the one interesting me but I was reluctant because I wanted the contrast of the $379 model). Amazon is taking pre-orders to ship on August 27th. I can’t wait!

Update: Did you know you can buy the Barnes & Noble NOOK ebook reader (WiFi + 3G) on Amazon? And the Sony Digital Reader? Note that each are a pound while the 6 inch Kindle is 8 ounces. And of course the Apple iPad Tablet (64GB, Wifi) which weighs in at a pound and a half.

53 Years of Nuclear Bombs

How many nuclear bombs have been exploded? Many people would say, "One, over Japan" when it fact it was two, one over Hiroshima and another over Nagasaki. Would you believe that Britain has exploded a nuclear bomb in the United States? Would you believe that in 53 years 2053 nuclear bombs were exploded around the globe? I find the following video unsettling. It left me feeling hollow in my chest and subtly angry.

flickr iPhone app 99% upload then fails

My iPhone refuses to upload a picture using the flickr app. It gets through 99%, reports complete, then says "Upload failed. Try later. Try again." Not much on The Googles about this. However, I believe the answer is in Flickr’s monthly upload limit for free accounts. After upgrading to Pro, my upload worked flawlessly. To the flickr iPhone app developers, your error message needs to be altered to encourage the purchase of a pro account.

View pictures mainly from my iPhone at http://www.flickr.com/photos/mccaughan and see excellent photography from Cathy with a real camera at http://www.flickr.com/photos/domesticpsychology.
