Blackberry Storm Customers Complain - A lot

http://news.cnet.com/8301-17938_105-10149766-1.html

It seems that RIM and VZW may have pulled the trigger a bit too early on the Blackberry Storm. I tried one out at the local VZW store a few weeks ago and came across very underwhelmed. At this point I'm thinking the iPhone (aka "Jesus Phone") or the Blackberry Bold may be my next PDA, with a good hard look at the T-Mobile G1 (or G2, when it comes out).

Pico Projectors - how to overcome your iPod's video drawbacks

I just read that a new class of projectors, called Pico Projectors, are poised to hit the market in the next few months. Microvision, based in Redmond, Washington, is slated to release a digital projector that will be just a bit larger than an iPod Classic (small enough to fit in a shirt pocket), and will allow video to be projected on just about any surface, up to six feet in size.

What an awesome idea! They are also working on a series of even smaller projectors that are small enough that they could actually be embedded in devices like audio/video players and cell phones. The company's Pico Projector (seen above), code named "More", is supposed to retail in the $300-$400 range and will be available in late 2008.

Sign me up! Imagine plugging your iPod into one of these beauties, and projecting your own movie on the back of the seat in front of you on an airplane. And if you can plug it into a laptop, and project presentations, there is even a business use for it--I can't tell you how many times I've traveled to a customer location and they were supposed to have a projector, and didn't--and it's pretty hard to show a decent PowerPoint presentation on a laptop screen with 8 people peeking over your shoulder!

The SunCell™ Solar Powered Charger

A good friend of mine who knows the founder of EcoPowered Solutions here in Colorado recently lent me a SunCell Solar Charger recently to try out, and I am very impressed both with the product as well as the company. In fact, I will have a hard time giving it back--I may just have to buy one of my own!

The SunCell Solar Charger

The SunCell is, at its core, a rechargeable battery that can be used to recharge any number of devices, including virtually any USB device (like cell phones, iPods/MP3 playe
rs, digital cameras, etc), plus a number of other devices with proprietary connectors (like Motorola and Nokia phones, for example). The battery holds enough juice to fully recharge a typical mobile phone three times. Unfortunately, it can't recharge laptops, as they generally require much higher voltages to recharge, and some (like Dell) also have proprietary charging mechanisms. The device comes with a selection of 16 "power tips" that can accommodate a wide variety of gadgets. The device is small and lightweight: 5.5 inches x 4 inches x 1.4 inches and 0.5 pounds in weight, and it's available in a number of colors.

The product's "Inspector Gadget" feature is that it can be recharged using a number of methods, the coolest of which is two solar panels that are included with the unit (it opens using a 'clamshell design' to expose the panels. The SunCell can also be recharged using an external USB port (e.g. from a computer or a USB wall charger). It works as advertised--the internal battery fully recharges in 3-5 hours from an electrical outlet or a laptop and will recharge using solar energy (strong sunlight--outside is best) in 8-12 hours, depending on how depleted the battery cell is. The SunCell's battery capacity is 3600 maH (about what a laptop battery holds) and the solar panels can output a peak of 1.5 watts. The device has selectable output voltages that are sure to accommodate virtually any device, including 4.8v, 5.8v, 8.4v and 9v.

The SunCell retails for $125 US, including a full selection of power tips, and you can purchase the units directly from the EcoPowered website.

In addition to being very impressed with EcoPowered Solutions' product, I am equally impressed with their mission. As one might guess, they are very much into promoting renewable energy, which is admirable in itself, but they also have a higher calling--providing their technology, free of charge, to organizations that utilize it to save lives and increase the quality of life in the areas they serve. Currently, donations to their program go directly to providing SunCells to Partners in Health, which is an international health services organization.
SunCells are currently being used by Partners in Health in many of the countries it has operations in such as Haiti and Malawi. They are used by the communities they work in to power cell phones in remote areas and they can be used as lighting systems for people that have no electricity. If you're interested in donating to this program, click this link.

This is a point to ponder. In addition to assisting organizations like Partners in Health, this device could very well save your own life one day. 15 years ago, I was an Emergency Medical Technician and volunteer fire fighter in a ski resort in the Colorado mountains. I also served on the local search-and-rescue, helping to locate and rescue people that had become lost in the wilderness.

There weren't as many radios and mobile phones then as now, but every time that I hear about people that get lost in the outdoors because 1) they relied on a GPS that lost power, or 2) their radio/mobile phone battery died and they weren't able to call for help, or 3) their camera ran out of juice and they couldn't save themselves by signaling to passing aircraft using the flash (you think that's funny? It works!), I think about this device. If you were to become lost or stranded, you could use the SunCell to recharge those devices that could potentially save your life, over and over. Pretty cool. It also has a built-in LED flashlight that will run non-stop for up to six days on a charge, which can also be used as a signal light. I think it makes a lot of sense to purchase a couple of these units to place in backpacks and car trunks--just in case--it could save your life some day.

The SPOT Personal Locator Beacon (PLB)

I recently attended the Denver Sportmen's Exposition, and tucked in between all of the fishing/hunting lodges, wonder glass cleaners, and knife sharpeners was a booth for the SPOT Personal Locator Beacon, also known as a PLB.

PLBs are small Blackberry-sized devices that allow you to either notify the authorities that you need help (also known as "911" mode, named after the U.S. emergency phone number), or to "check in" to let your loved ones know where you are and that you're OK. These are NOT satellite phones--you can can't use them to communicate via voice--but they are capable of transmitting your GPS fix to orbiting satellites from many places on the earth. The "check in" service allows your friends and loved ones to access a Google map that shows all of the places that you checked in, along with the date/time. The device weighs 8 ounces and will run 14 days in "SPOTcast" mode (using the check-in feature) and 7 days in 911 "emergency tracking" mode. It also has replaceable AA batteries, in case the original batteries fail.

I've seen PLBs for a number of years, but they were always really expensive (like $500+). What struck me about the SPOT is the price: $149, plus a $99 annual fee for the service. The coverage is also pretty good: virtually everywhere in the U.S., Canada and Europe, plus portions of South America, Australia, Asia and Northern Africa--click here for a complete coverage map.

This could be an invaluable, potentially life-saving device for outdoors types, especially since it works in areas where mobile phones do not. It also gives the outdoors types' loved ones peace of mind. Either of these advantages would be easily worth the $150 price tag!

My Journey of Discovery through HDTV Land

I recently began investigating high-definition TVs (HDTVs), as our venerable (read: 9 year-old) 53" Sony projection TV is just about to kick the bucket. Some of you may be surprised to hear that I haven't made the leap to HD by now, but the combination of high cost and lack of HD content has kept my gadget geek side at bay until now.

This blog entry is intended to help me understand (and remember) some of the lingo, technology and jargon that swirls around the world of HD--and hopefully it will be of use to you as well. I'm going to separate this into four sections: 1) HD Standards, 2) HD TVs, 3) Broadcast HD Sources, and 4) HD DVDs/Players. In order to increase readability and allow me to separate this into manageable chunks, I'll split it into two pieces: #1 and #2 will be in this post, and #3 and #4 will be published in a subsequent post.

I welcome your comments/corrections on any of this--since I'm an HD newbie, I'm bound to make mistakes. This information is my own interpretation of information that I've culled from a variety of sources: Internet, Big-Box sales personnel, friends, etc., and not all of it may be accurate.

1. HD Standards

One of the most confusing aspects of HD are the variety of video standards floating around: 720p, 1080i, and 1080p and the three most prevalent standards, and a good understanding of what these numbers mean is critical to purchasing the right set for your needs (and budget!).

In order to understand what these standards mean, it's first necessary to understand how TV resolutions are described. The number portion of the standard indicates the number of vertical lines (also known as "resolution) that comprise the video picture--720 or 1080 lines. The general rule-of-thumb is that the higher this number, the better, as the more lines of resolution there are, the closer together they are, and the finer the picture. This is especially critical as the size of the TV gets larger--especially over 46 inches or so.

By comparison, regular US TV broadcast standards (known as NTSC) have only 486 lines of resolution (sometimes referred to as '480i'), so 720p sets represent a ~148% sharper picture than conventional TVs, and 1080i/p TVs are ~222% sharper (note that these figures only consider the vertical resolution). Specifically, 720p has a resolution of 1280x720 pixels (horizonal x vertical), and 1080i/p resolution is 1920x1080. European broadcasts use the PAL standard, which has 576 lines of resolution (also referred to as 576i).

Next, let's examine the little letter after the vertical resolution number: i and p. 'i' stands for 'interlaced', and 'p' stands for 'progressive'. Interlaced, which dates back to the original NTSC and PAL standards, means that the vertical lines on the screen are painted either even or odd first, followed by the opposite--in other words, only 1/2 of the screen is painted per pass, or refresh. Progressive indicates that the TV screen is painted one line at a time, and the entire screen is painted per refresh. Progressive monitors are considered superior as they have less 'flicker' (which is a side effect of interlacing).

Based on all of this, it is safe to assume that 720p is clearly better than 480i/476i, 1080i is better than 720p, and 1080p is the best of all. Interestingly, 720p is actually much closer to 1080i than you might think--progressive scanning makes up for a lot of the flicker that comes with interlaced signals.

Unfortunately, the ability to take advantage of the various HD resolutions is a factor of the HD source's ability to actually provide that much resolution (more on that later).

2. HD TVs

There are a bewildering number of HD TV technologies on the market today. In order to prevent writing the great American novel, I'll condense them down into two main categories: flat panel and projection TVs.

Flat Panel TVs

Flat Panel TVs have several key advantages. First, they are very thin and light-generally only a few inches deep and under 100 pounds in weight, which allows them to be mounted on walls. Tube-based TVs can weigh several hundred pounds and be 18 inches deep, in comparison. Flat Panels also use less electricity and put out less heat than comparable tube TVs.

There are two main types of flat panel TVs: LCD and Plasma. Both technologies have advantages and disadvantages. Plasma TVs, which operate on the principle of exciting luminescent gas, are generally less expensive than comparably-sized LCD sets. Plasma sets feature good color and black rendition and work well for signals with a lot of movement (like sports). The main drawback of plasma sets are that they are prone to "burn in" (if the set is left with the same image displayed for too long, the image may be permanently "ghosted" on the screen), and plasma sets are also reported to have lower life spans when installed at high altitudes (generally over 6,000 feet). There are a new crop of plasma TVs that are rated to work up to 9,000 feet; if you live at one of these altitudes, it would be best to make sure you buy a high-altitude rated plasma or an LCD panel. Also note that the noble gases used with plasma sets gradually fade over time, and plasma sets also require a "backlight" that must be replaced over time.

LCD panels rely upon millions of discrete LCDs to comprise the video picture--virtually the same technology that computer flat screens use, only much larger. Advantages of LCDs include long life, low power consumption, no burn-in problems, and high-altitude compatibility. Disadvantages include less vibrant color than plasma and the tendency for high-speed images to leave a trail (the reaction time of LCDs are typically much slower than plasma). A new crop of "120 Hz" LCD TVs is reported to help solve many of the speed problems, but at a premium. LCD TVs are also generally more expensive than comparable plasma sets, although the gap is narrowing. LCDs also require "backlights", which need to be replaced over time (generally every 9,000 to 12,000 hours).

Rear Projection TVs


There are a mind-numbing number of different rear projection HD TVs. Projection TVs are generally much less expensive than flat panel TVs, and they are also deeper (only some projection TVs are thin enough to be wall mounted). Many projection TVs also have a much narrower range of viewing angles than flat panels (in other words, they become dim as one moves to the extreme left or right side of the TV).


The best known HD projection technology, Digital Light Processing (DLP) relies on millions of microscopically tiny mirrors that are laid out on a semiconductor chip. Light is reflected from the mirrors on to the screen, and each mirror corresponds to a pixel on the screen. Advantages of DLP include low cost, good color and movement rendering, no possibility of burn-in, and an easily replaceable light source. Disadvantages include poor viewing angle, possible eye strain (reported by some users), fan noise (in some units), and much thicker cabinets than flat panels.

Other HD projection technologies on the market include LCoS (Liquid Crystal on Silicon) and LCD projection. I have not done much research on the non-DLP projection sets to date, although DLP repoertedly has the thinnest cabinets of the three projection technologies.


Coming Soon

As mentioned at the top of this entry, I will be publishing the second half of this posting shortly, which will cover various live HD content sources as well as the options for DVD sources.

Unboxing - What Inside High-Tech Gadget Packaging

This is a really interesting idea--a website (a sub-site of Gearlive, actually) dedicated to unboxing all sorts of high tech gadgets, including the newest game consoles, PCs and laptops, phones, mp3 players, and cameras.

Not only does the site give you an idea as to how easy it is to unbox and install a particular gadget (look at the Apple products, for example--they set the standard for ease of installation), it also gives you a peek inside the latest technology--like the XBox Halo3 game console.

A very cool idea--everyone in technology should take a look at this site for ideas on how to (and how NOT to) package their products.

The Starbucks iTunes WiFi music store reviewed | Gear Live

Starbucks iTunes WiFi Music Store - Brilliant!

Starbucks has partnered with Apple to create their own branded iTunes store. This is in itself a good idea, as it allows Starbucks patrons to purchase music they may have heard playing in the Starbucks stores. Starbucks and T-Mobile took this concept one step further--if you happen to be in a Starbucks store with your laptop, iPhone or the new iPod Touch device, and you like the music you hear playing, you can connect to the iTunes store using T-Mobile's WiFi hotspot, free-of-charge, to purchase and download music on the spot. The Starbucks iTunes store also displays the last 10 songs that were playing in that particular store, making it much easier to buy that track that you really liked when you heard it playing. (Note that the free WiFi access only allows customers to browse and download music--not the general Internet service).

This is not only marketing genius, but when you consider the technical infrastructure that would be required i order to make this happen, it's down-right impressive. Consider that they had to integrate the music playing over the Starbucks channel on XM with the Apple iTunes Store systems, along with the T-Mobile hotspot billing systems. I'd be really interesting in discovering more about how they pulled that off from a technical perspective.

The link below points to a really good review of the Starbucks iTunes Store by GearLive, including screen shots taken from inside a Seattle Starbucks store.
