Apple’s Lightning Connector

clock November 5, 2012 22:53 by author Ty

Lightning is a new power connector designed created by Apple for its 2012 products such as the iPhone 5, the IPod Touch 5th generation, the IPod nano 7th generation, the iPad 4th generation and the iPad mini.


Lightning is an all-digital 8-pin port connector, Apple’s replacement for its 30-pin port connector. Unlike the 30-pin connector, the new 8-pin connector is reversible and can be inserted into the device with either side facing up. Furthermore, the 8-pin connector’s key benefit is its size and it is approximately 80 percent smaller than the 30-pin connector. To comply with the 30-pin connector devices, Apple sells Lightning-to-30-pin-adapters for $29.


According to the latest news from Apple Insider, Belkin has announced two new accessories designed for Apple’s lighting connector. They will be the first official third-party lighting accessories to hit the market. Belkin’s lightning accessories are now available for pre-order on the company’s website and in-store purchases will be available in mid-November. It is said that Belkin’s car charger for lightning with a 4-foot lightning cable and over-voltage protection will be sold at $29.99.

Quick Charging Li-Ion Batteries Using Graphene

clock August 21, 2012 01:10 by author Ty

Development of a new type of battery using the world’s thinnest material could power our future devices with fast charge and discharge rates. Currently, we are using today’s lithium ion (Li-Ion) battery technology to power our laptops, tablets, cell phones, digital cameras, camcorders, and other portable electronic devices.  Current Li-Ion batteries mark today’s industry standards. R&D engineering researchers at Rensselaer Polytechnic Institute are taking Li-ion battery technology to the next level.  Intentionally blemished graphene paper is used to create quick-charging Lithium-ion batteries with a high power density.

Graphine Batteries

Graphene is an allotrope of carbon, which is structurally modified by bonding atoms together from the element in a different manner. Conventional Li-ion battery cells use carbon, metal oxide, and a lithium salt electrolyte in an organic solvent. Graphite is the most popular electrode material in batteries. The graphite is replaced with graphene paper, which has been photo-flashed and zapped with lasers to increase blemishes, countless cracks, pores, and other imperfections. This will transform the graphene paper and new battery design with high-rate capable anodes for lithium-ion batteries.

Graphine Li-Ion Battery

With the success of a high power density graphene Li-ion battery pack, holding large quantities of power, quickly holding charge and releasing this energy would bring a huge solution. Complex paring of Li-ion batteries and the use of super capacitors wouldn’t need to be extensively used in electric cars. A new graphene Li-ion battery pack with large power densities and energy densities would allow very fast charge and discharge rates. Imagine fast charging hybrid cars, all-electric cars, and solar powered vehicles becoming a reality.  Quick charging laptops, tablets, cell phones, cameras and mobile devices wouldn’t need to be recharged overnight. The world would be a very mobile place, without the need of an electrical outlet every few hours.

Curiosity Power Source Batteries for the Mars Rover

clock August 8, 2012 01:49 by author Ty

The Mars Curiosity Rover is powered by plutonium, which is a nuclear power source to charge its batteries and fuel its onboard systems throughout its planned two-year mission on Mars. The battery packs are made up of two separate battery systems, charged by the nuclear power source. These battery packs are 2 Lithium-Ion rechargeable batteries to meet peak demands of rover activities when the demand temporarily exceeds the generator's steady electrical output levels. The Power Source unit produces enough electricity to power all Mars rover activities.

If you look at the tail section of the Curiosity Mars rover, you will notice a cylindrical unit sticking up at a 45 degree angle. This unit is the Power Source that runs everything on Curiosity. Below are detailed technical specifications off of the JPL NASA Web site.

Curiosity Mars Rover Power Source


Curiosity Technical Specifications – Mars Rover Power Source:

  • Main Function: Provide power to the rover.
  • Location: Aft side of the rover.
  • Size: 25 inches (64 centimeters) in diameter by 26 inches (66 centimeters) long.
  • Weight: about 99 pounds (45 kilograms).
  • Power Source: Uses 10.6 pounds (4.8 kilograms) of plutonium dioxide as the source of the steady supply of heat.
  • Electrical power produced: slightly over 100 watts. 
  • Batteries: 2 lithium ion rechargeable batteries to meet peak demands of rover activities when the demand temporarily exceeds the generator's steady electrical output levels.
  • Reliability: NASA has used this power source reliably for decades, including the Apollo missions to the moon, the Viking missions to Mars, and the Pioneer, Voyager, Ulysses, Galileo, Cassini, and New Horizons missions. 
  • Safety: Built with several layers of protective material to contain its fuel in a wide range of potential launch accidents, verified through impact testing. Manufactured in a ceramic form, is not a significant health hazard unless broken into very fine pieces or vaporized and then inhaled or swallowed. In the unlikely event of a launch accident, those who might be exposed would receive an average does of 5 to 10 millirem. The average American receives 360 millirem of radiation each year from natural sources, such as radon and cosmic rays.

The Mars Rover Curiosity is projected to last two years off of its nuclear power source and battery pack combination. Curiosity’s power source could last as long as six to twelve years. This would keep the operation running longer, as seen in previous Mars rovers, such as Spirit and Opportunity. For more information on the Curiosity Mars rover, check out the following sources.

Apple iPhone 4S Runs HTML 5 Faster Than Android Samsung Galaxy Nexus - PerfMarks Report

clock March 5, 2012 21:29 by author Ty

Which device runs HTML 5 faster? Apple iPhone 4S or Samsung Galaxy Nexus?

HTML 5 has been tested and proven to run faster on the Apple iPhone 4S running  iOS 5.0.1, when compared to the Samsung Galaxy Nexus running Android 4.0 Ice Cream Sandwich. This claim has been proven by a recent study at Spaceport.io with a benchmark called the PerfMarks Report. The PerfMarks test determines the number of moving images on a screen at a rate of 30 FPS (frames per second). Below are recent scores of the Apple iPhone 4S vs. the Samsung Galaxy Nexus.

 Apple iPhone 4S vs. Samsung Galaxy Nexus

From Spaceport's data above, we see the Apple iPhone 4S is significantly better at handling HTML 5 than anything else out on the Android market. The iPhone 4S is able to run 252 images vs. the Samsung Galaxy Nexus at 147 images at 30 FPS.

If you want to see a full list of Spaceport's data that dates back to early 2009, check out the timeline below. You will find comparisons with the iPhone 3GS, iPad, iPhone 4, iPad 2, iPhone 4S, Motorola Droid 2, Samsung Galaxy Tab 10.1, Kindle Fire, and the Samsung Galaxy Nexus.

Apple iPhone VS Google Android

As you can see, year after year, Apple has beaten Android devices in both the smartphone and tablet markets with HTML 5 PerfMarks testing scores. However, the Android OS is closing the gap fast with new and faster releases such as ICS (Ice Cream Sandwich). The proposed and upcoming Google Android Jelly Bean and Key Lime Pie OS releases might give Apple a run for their money with speed.

On a side note, Google Executive Chairman, Eric Schmidt stated February 28, 2012 at Mobile World Congress 2012 that people use Google Chrome because it is the most Secure, the Fastest, and it is Free! You can be rest assured that Google has their eyes set to be the fastest smartphone on the market. Here's the video of Eric Schmidt's quote about Chrome being the fastest! We skipped to 1:42 in the video to get straight to the point.
