"Software engineer Ken Shirriff took a close look at 12 different USB power adapters and confirmed what we already suspected -- that counterfeit chargers are junk. They are poorly constructed and can cause serious damage to both your devices and yourself."

"As someone who primarily taught math and science when I was a classroom teacher, I associated robots, robotics curriculum, and robot apps as things that were only used in those subjects. However, this past year my school received a robot grant that provided ten robots for us from the company Sphero. Sphero emphasizes the power of play in education and has a variety of lessons that are aligned to the Common Core and Next Generation Science Standards on their website. They also have a number of STEM challenges  in the form pre-designed engineering projects designed for collaborative group work with students and are helpful for teachers using the robots in their classes. Sphero is a robotic ball that can pair with an iPad, tablet, iPhone, or smartphone through Bluetooth, and getting started is relatively easy. Once you are ready to use Sphero, you take it off the charger stand and give it a "tap-tap" to "wake it up." When the robot wakes up, it starts to flash three different colors until it pairs with the device you are using it with via Bluetooth. Once it turns blue, then you know that it is paired and ready to go. There are at least 14 different education related apps that are available with Sphero: some of them use augmented reality technology, some of them teach the basics of coding, while others allow students to draw on a tablet to manipulate the color and movement of the robot. During the last week of June, I did a presentation at the ISTE conference with many other educators from all over the country who also received the robot grant. What amazed me was that people who taught subjects like language arts and social studies found incredible ways to integrate robotics into their curriculum to create some really engaging lessons for their students."

"It really all started with the 20+ iPads we loan out to educators. Those suckers are constantly in demand and constantly in need of charging. They're each firmly encased in Fintie Kiddie cases, which, laugh all you want, those things can stop a bullet. And they stand up. And they recline, have carrying handles and come in neon colors, perfect for locating 20+ loaned out units during the chaos of an event, but that's a whole other blog post. Anyway, we've been loaning these iPads out in tote bags, and just tossing the chargers in higgledy-piggledy. Mainly because if you have done any shopping around for charging carts you likely have needed to be resuscitated at least twice when looking at the prices. The cheapest we could find that works with our beloved Fintie cases started at $399.00, and there was no guarantee everything would fit. We've borrowed another department's iPad charging tray a couple times, but a) it cost them closer to $1,000.00, b) weighed close to 25 lbs and c) had no wheels, thus entailing that their tech guy** lug it four blocks each way. The thing about the Fintie cases is that part of their magic durability is that they surround the iPad in thick molded foam rubber - perfect for tossing in bags and bike panniers (guilty!) but problematic for trying to buy a pre-made charging cart, as the slots in those are generally cut for slimmer, uncased iPads. Plus can we get back to the whole cost thing? Are school districts really running around with so much cash? I know I'm not. And thus, with no more rambling, I present: How to Build Your Own iPad Charging Cart Out of Office Supplies"
