As any casual TV shopper may know, venturing into your local electronics store's HDTV section can be a bit confusing, to say the least. Unless you keep up with the ever changing technology and terminology of the industry, you risk making a mistake, or worse - wasting money, when the time comes to purchase your new set.

This article by George Ou should help sort things out. He covers the advantages and disadvantages of:

Projection: Pro: price. Con: viewing angle.
Plasma:Pro: resolution, colour, viewing angle. Con: price.
LCD:Pro: picture quality. Con: expensive large size sets.

George also advises, bluntly, against getting suckered into buying so-called high end cables:

Consumers need to get the concept of "monster cables" out of their minds since they DO NOT apply to the digital world. There is zero difference in quality between the cheapest $12 HDMI to DVI cable versus the $100 gold plated "monster cable".

He also makes available some colour gradient graphics and explains how to use them in testing the colour quality of an HDTV.

This is a great piece for anyone in the market for a new HDTV, and it's especially useful for those of us that may be more than a little confused and/or overwhelmed by variations in HDTV technology.

Cables and desk clutter are often the bane of many people's home office experience. Decluttered.com demonstrates one way to get a handle on the situation by making clever use of a pegboard and wires. A pegboard is mounted on the underside of the desk and any routers, powerbars, modems and the like can be lifted off the ground and secured to the pegboard, bringing the plethora of associated cabling along for the ride.

The site has a lot of pictures of the process and results, and has recently added pictures sent in by people who've tried the pegboard method on their own desks.

Total cost: $33.42 CDN.

Enviroscaping to Conserve Energy is an interesting guide on maximizing your home's energy efficiency by modifying various aspects of its immediate environment, or "Microclimate".

A microclimate is any small, local area within which the effects of weather are both relatively uniform and easily modified. Microclimate modification involves the best use of structural and landscape design elements to maximize or limit sunlight, shade and air movement. Structural modifications involve the design of the house and associated construction (walkways, fences, patios). Landscape modifications (enviroscaping) involve the use of plants to further increase or decrease the impact of sun and wind upon the local environment.

This site, which applies mostly to homes in hot weather climates such as Florida, offers a lot of interesting ways that a home owner can creatively reduce energy usage. Some of the suggestions apply to potential home builders, such as home orientation (a house is more energy efficient if it is oriented with the long axis running east-west), however the majority of the tips apply to existing residences.

There are many examples of "enviroscaping" strategies on the site, such as optimal tree placement for maximum shading, tree type (In winter, the sun is low in the southern sky. Southern exposures of a home in north and central Florida can receive free benefits of passive solar heating, provided that deciduous trees are used along the southern exposures. Deciduous trees shed their leaves in the fall, and are bare during the coldest months of the year.), fencing options (fences vary in amount of air circulation), shrub and vine placement along walls, increasing air conditioner efficiency and much more.

Here's an in depth article on turning an average basement into a slick home theatre room. The author illustrates his plans with CAD drawings while detailing many, many issues to consider, including the differences between LCD and DLP projectors, mounting and image keystoning issues and the secrets of progressive scan DVDs.

One of the more interesting things in this piece is how the author used the hard paper columns that builders use to pour concrete along with some marble paint to create some faux marble columns for $20.

A relatively new company called 'Cydus' has addressed the dearth of residential RFID access controllers in the marketplace by releasing a pair of modern electronic deadbolts. The locks operate as you may expect RFID proximity access controllers to, however, this unit, the MyKey 2300, unfortunately requires that a button be pressed before the unit is ready to read the keychain RFID tag. The higher end unit, the 4000, only requires the card to be in close proximity to the reader for activation. Besides it's raison d'etre; the convenience of keyless entry through small RFID cards, the deadbolts have some interesting features, including this backup battery system in case the unit's batteries die:

Simply touch a 9v battery to the built-in battery terminal and your MyKey 2300 is up and running. The MyKey even stores all of your existing security keys, so even if it's without power, when you turn it back on your access cards and pin combination are fully intact!

Lost or forgotten RFID cards aren't the end of the world either, as the unit comes equipped with a nicely hidden keypad for which to enter your password.

Australian company Avega Systems are developing WiFi speakers that connect to your wireless home network. The speakers, called "Oysters", play digital audio streamed directly from your computer. Listeners can control, browse and select media from their PC through the Oyster's graphical remote control. The speakers will also accept input from a CD/DVD source and wirelessly distribute the audio to the other speakers in the room. The Oysters also will accept iPods or other MP3 players, via USB port, which will, again, trigger the connected speaker to distribute the audio via WiFi.

The speakers feature wireless connectivity (801.11 a/b/g), support for DTS, 5.1 surround as well as MP3, OGG, WMA, AAC and FLAC digital audio formats.

The unit also has 2 S/PDIF optical connectors and USB port for wired connections.

Although the title sounds like an Ebay auction that offers you 10 foot TVs for $2.99, this howto from Projector Central really does deliver a thorough walk through on constructing a projector screen yourself. The article details, in 7 steps, how you can create a 100 inch, 16:9 screen for $98.50.

Here's the criteria they were after, from the article:

It must be cheap. Total budget for all materials to make a 100" diagonal 16:9 screen, including frame, must be less than $100.

It must be simple and quick to assemble. We did not want to make a lifetime hobby out of making a screen. We wanted the materials to be easy to find, and we wanted to put it together in less than two hours of invested labor.

It must be easy to install. We wanted a no muss, no fuss solution with a fixed frame that we could hang on a wall in a matter of minutes.

It must perform!!! We had no delusions that we could invest a hundred bucks and a couple hours labor and come up with a screen that would match the quality of the Stewart screens we use in the projection labs. But how close could we come? That was the challenge. And as you will see below, the results were surprisingly good.

If the cost of the screen is what's been holding you back from buying a projector, perhaps a frugal DIY solution such as this one will be your tipping point.

Article: Make a 100" Screen for under $100

HomeTheaterBlog has documented a recent LCD television wall mounting and has shared the details for anyone looking to undertake the installation on their own. The installer lists the tools you'll need for the hanging and also covers finding an appropriate mount location, stud finding, cabling issues, etc.

About.com also offers some wall mounting instructions, including tips on handling situations where cables aren't (or can't be, for whatever reason) behind the wall:

We can either place an obstacle under the television, which would look odd, or we can cheat the eye with camouflage. I have a friend who had this very problem, and his solution was to create a molding that would be used as a cover for his cables. He painted the molding the same colour of his wall, and when placed over the cables it looks like part of the wall. Granted, it's raised about 2-3 inches off the wall, but it looks very natural. As far as supplies, small strips of wood (a 1x2 for the sides and 1x4 for the face) cut to the length of the TV to the floor should be enough to make such a piece.

Wikihow.com provides a more orderly and straightforward, step-by-step instruction set, if that's more your bag.

Home Heartbeat is a notification system that continuously monitors your home's electrical appliances, faucets and other household devices while conveniently sending status data to the "Home Key" keychain, via the ZigBee wireless communication protocol. The system's base station offers internet connectivity that allows for remote monitoring, and the device can also be configured to issue status updates through email or text messages to the homeowner's cell phone.

The system is built in a modular fashion, meaning the device can couple with many different types of (Home Heartbeat) sensors, as they become available. From the site:

The backbone of the Home Heartbeat system is a network of detection sensors: water sensors, open/closed sensors, power sensors, reminder and attention sensors. The sensors can alert the homeowner to a wide range of problems, including pipe leaks and flooding, opened doors and windows, and appliances that are left on. An additional feature is a water shut-off valve that can be controlled and activated by any of the sensors. Reminder and attention sensors can be set to alert homeowners about easy-to-forget tasks, such as changing batteries in smoke detectors or cleaning out the gutters.

According to Fast Company, the basic starter unit offers only one sensor as well as the base unit and keychain and will retail for $149 US.

Ideal Homes of Norman, Oklahoma has produced a "Zero Energy Home" that sells for just under $200,000. ZEH have been produced before, but have tended to be much more expensive and thus out of reach of the average consumer.

The home is connected to the power grid, but attempts to satisfy as much of it's own energy requirements through alternative, renewable methods as well as utilizing high efficiency construction techniques, resulting in net zero energy consumption for the year.

From the site:

"Zero energy homes get a black eye in my mind," says McKown, "Every time they do a demonstration site, they run out and they hire some brilliant architect and they go off and they build this one-off amazing house that sticks out of the neighborhood like a prairie chicken, and it costs a million dollars. Everybody looks at that and says, 'That's interesting. With enough money, you can do anything.' "We wanted to show that you can take any house out of a builder's product line," McKown continues, "and make it a zero energy house and it would look and feel and be just like a regular house, and it doesn't have to cost a million dollars. We could do it under $200,000."

The home made use of some interesting energy saving technology, such as:

• Tankless water heaters
• Ground source heat pumps
• South facing solar panels
• Low-e vinyl windows
• Fresh Air HVAC system

The home isn't currently one of the models that Ideal Homes sells. The company says that as people toured the home, they were more interested in the energy saving technology found in the home and using it to achieve super high efficiency, rather than actually having a home be zero energy, oddly.

Alan Lofft of Axiom Audio has written this informative article on the do's and don'ts of setting up your first home theatre. Topics covered include cabling choices, speaker positioning, video tuning, connection types and a ton more. Here's a television tip, from the article:

Try this simple visual test to determine if you have your video image too bright or contrasty. Look at any white area on the screen during scenes from live TV or a movie. It could be the white shirt or blouse on an actor or TV host. Are you able to see detail within the white areas? If you can't, then you are likely running the brightness too high, which washes out fine detail in bright areas. So lower the brightness and/or contrast. There's a reason why control rooms for TV productions and telecasts are always dimly lit: it's because video images on the monitors look best in a dim or darker room and the greatest range of colors and tones can be displayed.

Alan's website is also packed full of home theatre information and worth checking out.

Of the instant doorway arch kits we've seen, this one by Creative Corners looks like it may be the easiest to install, at least judging by the quick four step process outlined on their site. The company lists four arch sets, three of which come in two corner pieces, and the forth being a full, one piece arch.

According to this article at Beststuff.com, room acoustics are the most important factor in making a truly engrossing, quality home theatre system. The author, Norman Varney, says that a high end audio system can be wasted in an acoustically poor environment and that a decent system can sound great under the right acoustic conditions.

From the article:

Don't believe it? While working at the Science and Technology Center for Owens Corning, we built two identical rooms of average home theater size. Both included the same equipment, set-up and furnishings. One room had acoustic treatment in it and the other did not. I ran bio-feedback tests with a couple of dozen engineers playing the same 'Das Boot' clip for them in both rooms. We found that when subjects were in the room that was acoustically treated, their heart rate and blood pressure increased. Acoustics controlled their emotions. They did not understand why it was happening, or even care, but they all wanted it at home. A similar thing happened when I gave a little acoustic seminar for about a dozen teenage boys. In the untreated room they behaved like teenage boys, but in the acoustically treated room, it was like flipping a switch; they were totally focused on the movie, motionless, involved. So you see, it's real, and it's for everyone to enjoy. It's not just for audiophile geeks like me with golden ears.

Now don't get too carried away with improving your home audio experience or you'll soon find yourself dropping nearly $500 on volume knobs and the like.

Article: Room Acoustics Number One Component

We've seen solar powered address lights before, but it's always good to have more options on the market - and it doesn't hurt to have sleeker looking options such as these, either. The address numbers are available in two colours; natural aluminium and soon, black.

Perhaps taking cues from gadgets such as the telephone controlled thermostat and the telephone controlled oven, Plutohome produces a home automation appliance that is, conveniently, controllable via your bluetooth cellphone.

The unit is, however, a lot more than simply a home automation PC. In their own words, Pluto is:

the only all-in-one solution for your home that seamlessly combines media & entertainment, home automation, security, telecom and computing. You can control your whole house with a mobile phone, a touch-screen tablet or a web-interface. A Pluto system is like an appliance - not a computer. It is self-configuring, maintaining and updating. No technical skills are required to use or install Pluto.

There are some interesting features on the Pluto, such as television programs following you (or your bluetooth enabled cellphone, more specifically) as you walk from room to room, the ability to instantly turn any television into a videoconferencing unit, using your bluetooth cellphone as a remote control, and the system sending live video to your cellphone upon intrusion detection, as well as turning all the speakers on in the house to give you the chance to scare the potential burglar off, or perhaps make a dangerous new friend.

The software is free and open source and installs on any PC. The company recommends that if you plan a large system with many concurrent processes (streaming video on one TV with a video conference on another, for example), you'll want more in the hardware department, naturally. As far as peripherals go, the company is supposed to list it's recommendations here, but unfortunately, doesn't seem to list anything yet.

In the luxury home elevator world, there seems to be much more copy given to things like discriminating buyers, status, opulence and equity elevation than to sloth and physical fitness, but of course that might just be the jealousy talking.

If you've convinced yourself that a luxury home elevator is the true benchmark of luxury, then here are a few manufacturers that would be quite willing to set you up:

• Concord Elevator
• ThyssenKrupp
• Acme Home Elevators
• Inclinator.com
• Residential Elevators Inc. Motto: 'Just say no! - to stairs'. lol
• Dayton Elevator

If you want, you can design your future elevator cab yourself.

Here's an excellent soundproofing discussion over at studio-central.com. The thread begins with the oft recommended carpet and foam wall technique, which, as you'll read, is a total no-no to some - although it's not quite unanimously opposed. The carpet opponents believe carpet and foam to be dangerous potential fire hazards that, lacking any significant mass, have minimal soundproofing ability - which is hotly debated due to many people adding their anecdotal evidence to the contrary.

The discussion offers many links to different, informative soundproofing resources, including this document called Exposing Acoustical Myths (PDF), which really breaks down a lot of the misconceptions people have about the science of soundproofing a space. Another nice resource is this page that details the different drywall, stud and insulation configurations and their corresponding STC ratings. STC ratings are, according to stcratings.com:

...a single-number rating of a material's or an assembly's ability to resist airborne sound transfer at the frequencies 125-4000 Hz. In general, a higher STC rating blocks more noise from transmitting through a partition.

So, the higher STC the better. Another site worth checking out is Acoustics.com. They've made available an Acoustics 101 overview page, as well as handy project design resources that give detailed tips on designing all sorts of different types of rooms, including home theatres.

If you're renovating and considering putting in a home theatre, you may want to think about soundproofing the area. A quality soundproofing job will both prevent outside noises from entering your listening room/theatre and, conversely, give you the freedom to listen to whatever you like without having to disturb your house mates. Here's a drywall option, called QuietRock, that claims to be able to deliver that level of soundproofing. From the site:

• A single layer of QR-530 is equivalent to 8 layers of standard drywall (acoustically)
• QR-525 requires no power saw
• QR-545 is the only THX Certified soundproofing solution in the world
• 10x more reliable than resilient channel with no resilient channel liability risks
• Use like standard drywall (installs without special training)
• Fire rated. Environmentally friendly. Lab tested. Available in X, anti-mold, greenboard, blueboard, high impact and others

Installation video from the website available here (direct link to wmv video).

Wow. Here's another example of an amazing home theatre room, created by someone who obviously had a vision of what they wanted, and saw it through to completion. It's probably safe to say that the homeowner enjoys his cinema, no? The homeowner, Steve Jenkins, has posted galleries of the entire construction job, from sketch to finished room. Granted, it's definitely not the most subtle home theatre room in the world, but what a cool in-home movie experience it must create. It certainly looks like it would be easy to forget that you're still at home while enjoying your favourite Michael Douglas film.

This movie buff certainly takes his home theatre seriously. This is one of the more grandiose home theatres on the web (in recent memory, anyway). The owner obviously aimed for a true theatre experience, and given what must have been a sizable budget to play with, it's safe to say that he's achieved his goal.

Here's a nice touch, from the site:

One of the things I wanted to do is to provide a true cinema experience for movie showing parties. So I have three DVD players. One is used to show the theater intro (Welcome to the Regency Theater, etc.) which was done by Digital Forge, the other DVD player is used to show a movie trailer as a preview of an upcoming movie, and then the third DVD player shows a DVD if we're playing a DVD that night (alternatively, we show movies on the JVC 400 D-VHS player).

Like the Scarface poster before it, this Reservoir Dogs poster from L.A. Pop Art is created using the entire, handwritten (and legible) script. Add it to your movie poster collection in your home theatre, or give it as a gift to the Reservoir Dogs fan in your life. We purchased the Scarface poster and had it plaque-mounted as a gift for a serious Scarface fan in our family and it proved to be quite the hit. Sometimes it's fun just searching for the numerous obscenities scattered throughout the thousands of words...

A team of South African scientists led by University of Johannesburg professor Vivian Alberts has invented a solar power technology that is not only more efficient than current solar power solutions, but can be produced for, they claim, a fraction of the cost. From the article:

The South African solar panels consist of a thin layer of a unique metal alloy that converts light into energy. The photo-responsive alloy can operate on virtually all flexible surfaces, which means it could in future find a host of other applications.

The new panels are 5 microns thick, allowing for a tremendous efficiency improvement over older solar panels that measure about 350 microns thick.

Science in Africa has a November 2004 article with some additional details:

Prof Vivian Alberts of the Department of Physics at the Rand Afrikaans University in South Africa and team have developed and patented a novel manufacturing technique that finally makes it possible to construct CIGS solar panels at a very low cost. The method is easily upscalable to industrial output levels, while remaining much cheaper to produce than conventional silicon solar panels.

Work done over the last two years indicates that panels can be produced in commercial volumes at a cost of about R 500 for a 50 Watt panel. This is much cheaper than existing solar panels available on the market. CIGS is a remarkably stable material and conversion efficiencies should be sustainable for 15-20 years in any given panel.

It will be interesting to see if this technology is able to gain traction and catch on, offering both humanitarian and eco-friendly benefits to the world. Also worth watching is the film-thin photovoltaic solar strips developed by Nobel laureate Alan Heeger's Konarka.

ProjectorCentral has a large projector database with an extensive criteria filter that enables you to find the projector that works best in your space. If you're planning a home theatre setup, you'll want to know which projectors will work with your available real estate. Feed the site the distance the projector will be from the wall as well as the desired image size and you'll receive a list of suitable units. There is a plethora of other filtering options available too; price, brightness, HDTV compatibility, PC card reader and so forth. Also worth checking out is the site's top 20 overall projectors.

As we've said before, doorway arch kits seem like an easy way to make a doorway look a lot less cookie cutter while adding some extra character to your home. Although, as easy as the Insta Arch kit may be to install, the 15 minutes that the company is claiming it takes to do the job seems like a bit of a stretch, especially if you've seen their pictorial step-by-step instructions. That's not to imply that the installation would be difficult, but for a first time installer, 15 minutes seems a little optimistic, to say the least.

This is quite possibly the most wired, monitored, internet enabled home ever. Obviously privacy isn't too much of a concern with 9 webcams (some with nice pan and tilt action) and endless stats available openly and publicly over the net, including real time data on water usage, electricity usage, gas usage, doorbell rings, incoming phone calls with caller ID (and playable messages), alarm status, fridge door status, toilet flush count, washer/dryer monitor, temperature, rainfall, wind speed/direction and on and on. The amount of available data from so many different sources is staggering and must have taken a serious amount of time and a herculean effort to complete.

Engadget has posted a useful step-by-step howto on building your own Tivo-like home theatre PC (HTPC) using MythTV. They list each piece of hardware they used on the way to a successful, smooth install. From the site:

The total for the base system is $988. The addition of the TV tuners brings the grand total to $1126.

This price is probably beatable if you opt for a lower end processor, which will save you some money and really wont cost too much performance-wise provided the tuner cards you choose do hardware encoding. Tuner based encoding takes the vast majority of processing load off of the CPU. That being said, faster is always better when it comes to CPUs, generally speaking, so too severe a drop in clock speed will hamper menu navigation and other features which will detract from the snappy, slick user interface that you want in a PVR. If you're not too Linux savvy and aren't ready to do a manual install, a great way to set up MythTV on a PC is by using KnoppMyth. KnoppMyth is available on a downloadable, bootable CD that aims to make the MythTV installation as straightforward, user-friendly and painless as possible. If your system meets the hardware requirements, the CD will install MythTV onto your system while prompting you for only a minimal amount of configuration questions. If you encounter problems along the way, the KnoppMyth forum is invaluable. The site's admin, Cecil, not only tirelessly develops KnoppMyth, but also personally answers an unbelievable amount of questions on the forum, which, by the way, is packed full of information on getting up and running with MythTV - useful no matter what your method of installation.

Help friends, delivery people and vagrants find your home after dark with this solar powered address light. The unit lights up at dusk and automatically powers down at dawn. With three nights worth of light being supplied from just 4 hours worth of daylight, the unit seems very efficient.

If your home is like most, it will have come with a generous serving of the quick and cheap popcorn ceiling. If you're thinking about removing it in favour of something a little sleeker, check out what Jason from jasongraphix.com went through to achieve a clean, popcorn free look. Also, something interesting - and scary, as Jason notes:

Asbestos was used in some sprayed coatings for ceilings from 1935-1978 and can cause Mesothelioma & Asbestosis. It's a good idea to have a sample tested by an NVLAP approved testing center before getting started.

Here is a nice, very detailed page with instructions on building a spacious, double layered desk for your home office. According to the site, the desk had to be spacious enough to hold a lot, including three 21 inch monitors, a mini fridge, a Nintendo 64, a DVD player, a receiver, 3 computer systems and a whole lot more. Not surprisingly, the designer couldn't find a desk on the market that met his criteria for under $300, so he built one himself.

If you plan on redesigning a bathroom, or are lucky enough to be able to design and build one from scratch, here are some tips on making the most out of the space you have available to you, including things like where to place the toilet, amount of space required for sinks, showers and baths, as well as storage and safety ideas.

This page lists some very unusual Japanese home appliances and gadgets, written in classic Engrish, luckily:

Electric Bucket
Also in today, a bucket still exists in a home and it is used for various uses, such as bleaching of a shirt, pasting, and every clothing beginning. It has been said that it being dirty and putting into a washing machine suddenly washes by hand division washing of the thing, for example, a dustcloth etc., and important lingeries in a bath just for a moment.

It sure does.

Some interesting items:

A refrigerator that opens from either side

CathyMoore.com shows you how to stain concrete on the cheap. After some initial testing, trial and error, her floor seems to turn out very warm and inviting (and professional). The procedure seems relatively straight forward, although it looks as though there is definitely room for mistakes or misplaced mop strokes. This informative site, Decorative Concrete, says that the age of the concrete is not an issue, but the concrete's condition is. They also go on to caution:

Also remember this is an acid. PROTECT yourself from accidental splashes, spills and fumes. I like to have a 5-gallon bucket of water close by should I need to neutralize myself or anything else. Protect vegetation and other concrete surfaces. Don't inhale the fumes from the concentrate or your mixed solutions.

If you're looking for some ideas on geeky home improvement projects, CNET's site devoted to home technology howtos is worth a look. Projects include turning an old monitor into a television, making a home music server from an old PC, and setting up a powerline access network. The site isn't very heavy on the home automation front, although they have posted a decent overview article on the subject. The majority of the projects are related to networking and digital home entertainment.

Here's an informative video on laying ceramic tile in a bathroom. The Michael Holigan site has many videos such as this on a wide range of home renovation subjects. If you are considering laying ceramic tile, you may be interested in underfloor heating. Warmly Yours offers an online flash app to aid you in estimating the cost of an underfloor heating system.

This fire alarm has some interesting features. The smoke detector incorporates an aesthetically pleasing, daily-use, dimmable light that activates during an emergency. In case of fire, the unit communicates with other like units to illuminate an escape route through your home. The unit is powered by your home's electrical power, yet doesn't rely on it. Instead, the device employs a long life emergency back up battery that activates during an alarm. Now if it only had a wifi notification system...

If you're in the market for an HDTV, check out CNET's response to reader questions regarding HDTV, and specifically 1080i vs 1080p, source importance, price/value, and some gotchas:

Those of you thinking of running your PC through a 1080p set should be aware that you may not necessarily get to use all that extra resolution--even if you have the right high-end graphics card. For instance, the Sharp set we tested allows you to max out at only 1,280x1,024 resolution while the less-expensive Westinghouse LVM-37W1, along with Samsung's 1080p RPTVs and one series of high-end sets from Mitsubishi, accept true 1,920x1,080 resolution from a PC.

Mounted between your house and your attic, this 'Whole House Cooler' by Tamarack Technologies claims to be able to reduce the cost of home air conditioning by as much as 30%, all on the energy it takes to run two 60W light bulbs. From the site:

Engineered to reduce indoor air temperature, the HV pushes the hot air out of the house through the attic and replaces it with cooler outside air. The HV utilizes twin, high-tech, super efficient fan motors to minimize noise and power consumption. Our systems have the industry's only automatic door assembly, providing an air-tight seal with an insulating value of R-22.

The unit operates by remote control to boot.

Now here's a great idea. Gutter Stuff is a clever product that is so simple that it will leave many wondering how it was that they didn't think it up themselves. The product is a non-absorbent foam filler that fits in your roof's gutter, allowing water to drain out as normal while preventing leaves or unwanted debris from settling in. Check out the Gutter Stuff movie (direct link) for a demo.

According to the TMIO (Tonight's Menu Internet Ovens) website, the Connect Io Intelligent Oven allows you to begin cooking your food remotely, via either a telephone or internet connection. The idea is that you prepare your food ahead of time and place it in the oven, which keeps the food refrigerated until the cooking process is initiated remotely. Throughout the process, the display on your web browser exactly matches the display on the oven itself, in real time.

Program, command, and control your Connect Io oven remotely through your cell phone from anywhere in the world. No matter where you are, send commands over the Internet from your computer through a standard web browser.

Anywhere in the world? Sure, this might be handy to use from work or even to monitor your food from the pc in the other room, but who are they marketing to with 'from anywhere in the world'?

The Cooking Blog has an excellent list of tips and tricks for making life easier in the kitchen. Pros may know a lot of these already, but clever tips like: "Stuff a miniature marshmallow in the bottom of a sugar cone to prevent ice cream drips" are sure to be new to many, if not most, of the kitchen novices among us.

CurveMakers.com offers these clever doorway arch kits. Modern homes are rarely built with doorway arches, which were much more common in the past. Arches offer so much character but usually require some significant renovation dollars. These kits, which are reasonably priced, allow any standard doorway to be made to look more elegant and unique. Very nice.

There's just something appealing in the warmth of a candle's flicker, perhaps more so for those of us unfortunate enough to be experiencing the first hit of old man winter. People of all climates, however, can appreciate the beauty of these stainless steel oil lamp shadow projectors, by Adam Frank. The projected shadow size is "adjustable", obviously dependent on the base's distance from the wall. The site claims this to be the first in a series. The fuel cells lasts 17 hours.

Any Scarface fan on your list would be a happy camper after receiving this incredibly creative piece on Christmas morning. Decorate your basement or home theatre with a poster made using the entire 300 page hand-written script from the 1983 Pacino classic.

As the singularity approaches, one would expect that the amount of mopping being performed by humans would decrease as cute, dirt loving robots near ubiquity. The transition seems to have begun with the Scooba, from iRobot (of Roomba fame). iRobot is accepting pre-orders for the Scooba, which they say will ship in 8-10 weeks.

From the site:
Scooba is an intelligent and effective Floor Washing Robot. Scooba uses a four stage cleaning system to prep, wash, scrub, and dry floors all by itself. Scooba features iRobot's AWARE Robot Intelligence Systems. AWARE uses dozens of sensors to monitor the robot’s environment, and adjusts its behavior up to 67 times per second, ensuring that Scooba cleans effectively, intelligently and safely.
