Remote Visual Doorbell Clock

Hmm, a doorbell clock doesn’t exactly ring a bell in our books (pun not intended), but we guess there was enough research done to justify the existence of the Remote Visual Doorbell Clock. What does this $39.98 device do anyways? Regardless of whether it is powered by either an AC adapter or a quartet of AAA batteries, it will provide additional notice whenever someone is at your door step (an alert watchdog would do equally well, but at least you don’t have to clean up after the clock). Each time the doorbell is pressed, the clock will play one out of 32 selectable tunes, lighting up and flashing crazily away for 10 seconds to boot just in case it is late into the night and you are listening to your favorite relaxation tunes with a pair of noise-isolation earphones. Works great as long as you remain within a 50 foot radius from the doorbell.

Solar Chargers for Gadgets and Cellphones

Even though we've never reviewed them here (what's wrong with us?) we actually own and use both the Powermonkey eXplorer and the Solio Magnesium Edition Solar Charger and find both of them quite satisfactory. However either of these solar chargers run upwards of $100 to own. ThinkGeek has the budget conscious in mind with the Pico Freeloader Solar Charger, a compact and lightweight wonder that according to the specs provides power of 35 hours on mobile phone, 14 hours on iPod, or 1.5 hours on GPS on a single ten hour charge. What's particularly nice about the Pico is that you can recharge its internal lithium ion via USB in case of eternal winter (no sun). Oh, did we mention it's only $39?

Dell Streak Android Tablet

We were afforded the opportunity to preview the new Dell Streak cellphone prior to release, and our early hands-on review is extremely positive.

Full specifications:

5-inch capacitive multi-touch WVGA (800x480) display
Qualcomm1GHz Snapdragon ARM processor
5 MP rear camera, shoots 640x480 video
640x480 VGA front camera for video calls
Replaceable battery! (yay)
3.5mm headphone jack
3G/Wi-Fi/Bluetooth 2.1 connectivity
2GB Internal storage, Micro SD slot expandable up to 32GB

Best External Portable Speaker For iPod

Let's be honest - sometimes party music just sucks. Either your host has great taste in everything else but music, or a sub-party forms outside and is too far away to hear the music inside. The Altec Lansing iM-237 Orbit Ultraportable Speaker uses a 3.5mm input (or 2.5mm with adapter) so you can plug in your MP3 player, iPod, iPhone, Zune, or anything that can accept a standard headphones. The up-firing neodymium driver pumps out impressive sound in a 360-degree pattern - almost everyone who's seen me whip out this speaker and use it can't believe the sound it puts out. (The others were too busy dancing to notice!) If you're looking for the best external portable speaker to compensate for the wimpy sound most MP3 players put out with their built-in speakers, look no further.

Griffin FlexGrip Action Case for iPod Touch 4G

What's In Griffin FlexGrip Action Case for iPod Touch 4G?

FlexGrip Action Silicone Case
Handstrap

Pros:

Form-fitting silicone protects well.
Twin wedges provide a comfortable feel and solid grip.
Handstrap provides extra protection against "oopsies dropsies."

Cons:

Just a wee bit pricey at $29.99.
Handstrap could snap off if pulled too hard.
No screen protection.

Conclusion:

As of today, the iPod Touch 4G came out roughly two weeks ago. TWO WEEKS. Yet Apple Stores and other retail outlets are devoid of any cases for the 4th Generation iPod Touch! Could it be that Apple wants to make sure everyone sees what your new handheld looks like out of the case? We thought all the leaks about form factors for new iPods came from case manufacturers!?! All conspiracy theories aside, the Griffin FlexGrip is exactly what we are looking for the first of what will be surely many cases we will review for the new iPod Touch. It has an excellent look and feel, doesn't add much weight or thickness, and the dual-wedge design provides just enough extra width at the top and bottom to keep your new handheld from slipping out of your hand and on to the pavement. Recommended.

A primer on architecting nextgen smart LED lamp applications

Mukund Krishna

Light Emitting Diodes have come a long way from simply being cheap and inexpensive indicator lights on a myriad of electronic appliances. Today they are powerful source of illumination for a wide range of room, signage, displays and decorative lighting applications.
LEDs have been gaining importance over incandescent and fluorescent lamps for their capability to provide an equivalent amount of light for a significantly reduced intake of energy. Energy is one of the biggest debates of this century and is soon expected to become one of the most important issues concerning designers across the planet.
There are many potential benefits for lamp manufacturers to use LEDs. However, there are also many vendors trying to get in early on the LED action, so there is a pressing need for product differentiation. Also, with energy conservation and human labor costs being the prime design concerns, large lighting installations are almost expected to be ‘intelligent’.
The ability of a lamp to be able to communicate with a ‘parent’ controller, to monitor its own condition, modify its mode of operation based on this monitoring, and even ensure movement to a safe state during faults are all examples of what the next generation LED lamp is expected to be. This article will explore a few of these ‘intelligent’ options suited for LED lamps and the steps involved in achieving them.

Figure 1. Input Under-Voltage Lockout
The input voltage to an LED drive system is usually DC. The supply is either produced by an AC-DC converter working off the line or from a bus. Apart from providing the power for the LED drive, this supply will also be used to power the controller in the system (after converting to 5V or 3.3V as suited to the controller).
As shown in Figure 1, above, this controller power supply will usually be designed such that it will start operating when the input supply is a little above the required output voltage. For instance, a 5V regulator will start operating when the input reaches 6-7 volts. However, the steady state level of such a supply could be 24V supplying a string of 5-6 LEDs with 1A per string.
Once the controller powers up, it assumes that power is available and turns the LED drive system on (assuming it is configured as such), which will then try to draw the full power. If the input has reached only 10V by this time, the amount of current required from the input supply would be much higher than under steady state conditions, and it could collapse due to the sudden draw. The excess current draw could also surpass the ratings of the cable, connectors, and any other components on the power supply input, potentially causing permanent damage to the system.
In order to avoid this situation, the system should implement an ‘under-voltage lockout’ feature. The hardware for this involves a resistor divider setup that steps down the input voltage to a range that is tolerable by the controller’s inputs. The input is connected to a comparator internally.
The behavior inside the controller (firmware) should be designed such that the power section is turned on only when the input voltage has crossed the threshold that is deemed reasonable for operation.
Moreover, rather than turn on the power system as soon as the comparator switches, the firmware must poll the output of the comparator to check that the condition is consistent (since the comparator is a piece of combinational logic) and then turn the power system on. Figure 2 below shows the hardware schematic (simplified) that implements this feature.

Figure 2: Load (LED) monitoring
The load here has a constant current that is regulated through the LEDs. While it is true that the current regulation system is inherently monitoring the load, the purpose is to ensure that the correct load current is flowing. LEDs are prone to damage, which often shows up as open circuits or short circuits.
These kinds of faults can also be caused by loose wires, connectors, assembly issues on PCBs, and so forth. A short circuit on the channel could also be caused due to damage to the MOSFET (which plays the role of the switch).

Blu-ray Disc (official abbreviation BD) (Japanese: ブルーレイディスク Burū-Rei Disuku) is a high definition media format designed to supersede the DVD format. The format defines as its standard physical media a 5-inch (same as DVDs and CDs), 25 GB per-layer optical disc, being dual layer discs (50 GB) the norm for feature-length video discs, and the addition of more layers left open as a future possibility.

The name Blu-ray Disc refers to the "blue laser" used to read the disc, which allows for five times more storage than on a DVD.

Blu-ray Disc was developed by the Blu-ray Disc Association, a group representing makers of consumer electronics, computer hardware, and motion pictures. As of June 2009, more than 1,500 Blu-ray Disc titles were available in Australia and the United Kingdom, with 2,500 in the United States and Canada.[2] In Japan as of July 2010 more than 3,300 titles were released.[3]

During the high definition optical disc format war, Blu-ray Disc competed with the HD DVD format. Toshiba, the main company that supported HD DVD, conceded in February 2008,[4] releasing their own Blu-ray Disc player in late 2009.[5]
