It's Back Baby! iPad with Retina Display

Earlier this week, Apple sent out an email announcing the reintroduction of the iPad with Retina display (4th Gen). (See the press release here.) As you may remember, when the iPad Air was announced, the iPad 4 was taken off the market.

Well, it’s back baby! The iPad featuring the Retina display will replace the iPad 2 and will provide a great upgrade in power, performance, and value. The iPad with Retina display (4th Gen) features the Lightning connector, meaning that this replacement spells the end of 30-pin Dock Connector usage on any iPad or iPhone model. (Note that the iPod classic still features the 30-pin connection.)

The iPad with Retina display is $100 less than the iPad Air, coming in at $399 — a great value. We’re even offering free shipping for the next week, just for you! See our special below.

P.S. If your current accessories support the USB-to-dock connector, there may be no need to replace them completely. Apple makes a Lightning-to-30-pin Adaptor, found here.

A Candle-Powered iPhone?

If you’ve been reading Kibbles and Bytes over the past few months, you might have noticed I’ve written more than once about power and electricity. A few weeks ago, I wrote about generating electricity and how watts work. In that article, I mentioned that I’ve experimented with thermoelectric electricity generation and I thought this week I’d explain a bit about what that is and how it works. Spoiler alert: it’s pretty cool!

Sometimes it can seem like our iPhones are just electricity black holes. Sure, they last a pretty long time, but they still need to be charged a lot. This problem has spawned a whole line of products to help charge our devices when a wall outlet isn’t available. Most of these that I’ve seen are based on solar. We even carry a number of solar-based charging systems by Goal Zero. These are really cool products, and they work really well, but you probably already know the catch: Without sunlight, all they can do is look nice.

With this in mind, I set out to see if I could use thermoelectric generation to generate power on demand. Thermoelectric generation uses something called the Seebeck Effect. When you have two dissimilar metals joined together in a loop, a temperature difference between the junction points will create a current. You can use any two metals, but modern devices use a P-N semiconductor junction. These tiny semiconductor pieces are small (sometimes only about 1/8” cubes) so dozens (or more) are linked together to form a thermoelectric module. When you apply heat to one side, and cool the other side, the module generates electricity.

Could you use one of these to charge something like an iPhone? Yes and no. These modules are typically only 5%-8% efficient, so you need to work really hard to get appreciable power from them. In my design, I used a 5-watt module and a tea light candle. 5 watts is enough to charge a smartphone, but to get that power, the hot side needs to be about 300C and the cold side would need to be around 25C. That’s a hard differential to create, and I was never able to do quite that well.

There are things you can do with that low power though, and having it on-demand allows it to be useful in ways solar panels can’t be. One thing you can do is use your own body heat to power an LED flashlight. How is that possible? LEDs don’t need a lot of current, but they do need a few volts. The small voltage generated from the heat of your hand can be boosted to drive the LEDs. Thermoelectric generators also power deep space probes. Out of reach of the sun’s rays, they use heat from radioactive isotope decay to drive the generators. One final application is in waste heat energy harvesting. Thermoelectric generators are used to capture waste heat energy from industrial processes to improve energy efficiency.

Obviously you can’t use radioactive isotopes to generate your power, but a few companies have developed thermoelectric generators for the consumer market. The most famous is probably the Bio-Lite camp stove. They claim it can charge an iPhone, which is probably true, but I expect it takes a very, very long time. Since it’s a stove, you also can’t use it indoors. Another company, Tellurex, has a device you can run with a tea light candle (like my design) called t-POD. I actually bought that one to try, and I have to say, it works really well. It comes with a bright LED light it powers, but I’ve plugged in other small circuits as well.

For now it looks like we’re mostly stuck with solar when it comes to powering our devices without a wall outlet, but we might see that change in the near future.

Black History Month - Sanford, Florida's haunted past

The city of Sanford, Florida is in today’s headlines as the place where Trayvon Martin was shot and killed.

But the city is also haunted by racist memories of the past, dating back to the early days of baseball Hall of Famer, Jackie Robinson. After Robinson joined the Brooklyn Dodgers, he was sent to train with their minor league team, the Montreal Royals, in Sanford, Florida.

Upon arrival, Jackie Robinson was met by an angry white mob and members of the Ku Klux Klan. They refused to let Robinson practice on the field. It was reported that Robinson had to pry himself through a hole in the fence of the baseball field to join the Royals.

Later that night, Jackie Robinson was forced out of town to avoid serious injury by racist haters. Sanford, Florida’s nightmare of racial injustice went on for years after the Robinson incident.

The story of black civil rights activists Harry and Harriette Moore plagued the community for years. Harry Moore founded the first branch of the NAACP in Sanford, Florida. The teacher was a known advocate for voter registration and the salary disputes of black teachers. It was no secret that Moore’s involvement led to an approximate 31 percent increase of black registered voters in the mid to late 1940’s. Unfortunately, hatred stirred in the local KKK, which had widespread presence in Sanford, Florida. On December 25, 1951, the home of Harry and Harriette Moore was firebombed. It was the couples’ wedding anniversary. They died a few days apart.

Even now, decades after Jackie Robinson encountered one of the worst bouts of racism in baseball history and the death of the Moore family, accusations of racist police brutality and wrongful death continue to lie in the courtrooms of Sanford, Florida.

The city, which is approximately 30 percent black, is investigating the recent murders of three black men. With the shooting of Trayvon Martin by George Zimmerman on February 26, 2012, the entire country has rallied around the victim’s family, demanding justice.

Apple Releases Crucial Security Updates for Mavericks and iOS 7

Otherwise known as “‘Bout time! Patch those OS’s, people!” Last Friday, Apple released an update for iOS 7, and then followed with an update for OS 10.9 Mavericks this week. Both address critical vulnerabilities that the operating systems had, not the least of which included the potential for hackers to access encrypted data (meaning they could potentially grab usernames, passwords, location data and more).

iOS 7.0.6 Update
It was largely kept under wraps, but many have speculated that the security flaw in iOS 7 was one of the largest in Apple history. iPod touch, iPad and iPhone users were vulnerable to hacking via the installed mobile browser(s) — Safari et al. However, as these issues became known, Apple acted quickly, and the release fixes the outlying problem.

If you’re running iOS 7 and you haven’t updated yet, please do so now.

Either plug in your device and update via iTunes, or navigate to your Settings app (you may have noticed that red number badge — don’t ignore that bad boy!) and tap Software Update. Click “Download to Install”, agree to the Terms, and start downloading. Note: I recommend plugging in as a preferred method so that you can back up your data before updating!

OS 10.9.2 Mavericks Update
Mavericks was found to have the same security flaws, as well as bugs within Mail and Calendar that Apple wanted to address. The update primarily “prevents the validation of encryption certificates from supposedly secure servers” so you’ll want to make sure you update immediately. Additionally, the security fixes affect Mail, Calendar, iCloud and other apps on your Mac.

If you’re running Mavericks, do this update immediately after you run a backup!

Among other things, this update:

  • Adds the ability to make FaceTime audio calls
  • Fixes and issue that may cause VPN to disconnect
  • Improves Autofill compatibility
  • Resolves a Mail issue that prevented new messages from certain providers
  • Improves accuracy of unread counts in Mail

For the whole list, click here.
For detailed info about the security content, click here.

It’s important to note that this update is fairly substantial in size and what it covers, so definitely back up your important data first. Mail will re-index once the update is installed, but that should finish quickly enough (I have a loooot of mail — tens of thousands across seven accounts — and it indexed in about 3 minutes, so it’s not too bad).

On both my Macs, I had to manually run Software Update — it didn’t appear in the list right away. Under the Apple menu, select Software Update, and it should then pop up in the list of available updates. There is also an iTunes update available that you’ll want to run that fixes app crashing problems.
