A couple of years ago there was a Canadian company called Pulsar Advanced Technologies that announced that they were close to launching a Microwave based (instant) hot water heater, called the Vulcanus MK IV. There were a fair amount of stories on the net at the time, as it sounded like an interesting idea:

Powered by electricity and unaffected by the volatile gas markets, the Vulcanus MK4 can heat water from 35 degrees Fahrenheit to 140 degrees Fahrenheit in seconds and can source multiple applications at once: showers, dishwasher, sink usages and more. The Vulcanus MK4 is the size of a stereo speaker with a sleek modern look, making it ideal for condos and apartments, while powerful enough to serve the needs of any size family.

Canada's Globe and Mail newspaper ran the original story about the Vulcanus in November of 2005.

Well, perhaps unsurprisingly, it's now looking like the product is vaporware. The company's original website, Pulsar-at.com is now just some sort of placeholder site with faux content. The web address the company eventually moved to is also just a spamsite: Pulstech.com.

It's unlikely anyone is too shocked, given the delays and comments like this one from February of last year, where the Pulsar people told an email inquirer that they weren't planning on releasing the product at any point in the year, and this was about 14 months after the Globe and Mail ran the Vulcanus launch story in 2005.

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.

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.

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.

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.

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

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

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).

Proliphix produces an internet connected programmable thermostat that uses your LAN as its power supply with the aid of an (additional) ethernet power adapter. The thermostat's configuration/monitoring webpage is accessible from within your home network as well as from the internet. The company also offers wall mountable and paintable sensors to increase whole-house temperature accuracy. From the site:

Proliphix offers indoor temperature sensors, which can be mounted away from the thermostat so that temperature inside a home or small business can be averaged across multiple rooms to avoid hot or cold spots and wasted energy. With an optional Proliphix outdoor temperature sensor connected to a networked thermostat, the heating/cooling system can be controlled more precisely to efficiently and more comfortably overcome the indoor to outdoor temperature difference. The web browser configuration tool is simple to use and allows users to easily configure heating or cooling programs to maximize comfort and minimize energy use.

Smarthome sells the Proliphix NT20e, which is the same unit but with 2 additional remote temperature sensors, for use in monitoring different zones within your home or even the outdoor temperature.

GelFireplaces.com carries a few really nice flueless fireplaces that are fuelled by a clean burning alcohol gel, resulting in a smoke-free fire.

From the site:

Gel Fireplaces holds three fuel cans, each container burning approximately three hours and, because there is no flue, all the heat is projected into the room.

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...

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.

Warmlyyours.com has an underfloor heating (or radiant floor heating, if you like) Flash tool that allows you to draw a room to scale in order to produce a cost estimate to install their underfloor heating product. Underfloor heating seems like a better idea all the time, especially each morning as the cold winter months bring your bathroom ceramic tile temperature down to about absolute zero.

Warmlyyours isn't the only underfloor heating company around, of course. There are plenty, including:

Looks like the people from Pulsar Advanced Technologies, the inventors of the Vulcanus MK4 (now apparently the "Mark 4")microwave based hot water heater, have updated their website, adding some details on the unit:

The Vulcanus Mark 4, is a state of the art microwave hot water delivery system for the 21st Century. It is a containment field otherwise known as a Faraday box, much like the ones used in your microwave oven at home. The unit size is 24x14x7.5 and weighs only 20lbs. It was designed to save on construction costs, as a boiler room is no longer necessary but was made esthetically appealing so that it could fit as a ?stand alone? fixture. Its compact size allows the Contractor, Plumber or Developer the versatility to place the unit as close or as distant to the water outlets as is desirable.

Also, some details from the gas to microwave comparison page:

Electricity used only when required

No storage tank

Can fit on wall or closet

Eliminates possible bacterial growth

Corrosion of elements - nil

Unlimited hot water

Gas infrastructure not required

20 year life span

Weight-20lbs

It looks the company will be showcasing the Mark 4 at the National Hardware Show in Las Vegas in May, 2006.

More and more, we're seeing modern, beautiful and sleek in-wall fireplaces that look less like fireplaces than art, and Canada's ThermArt is no exception - in fact they make some of the nicest specimens, if you ask us. The company lists five models on their website: the Teardrop (pictured), Quote, Flow, Bouquet and Clarity. Be sure to check out their installation gallery, available for your surfing pleasure.

If you reside in Europe, Safretti produces similarly stunning units.

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.

Apparently there are quite a few options in the on-demand, instant hot water department! We've seen the Quooker instant boiling water faucet, as well as the very interesting but not-yet-available Vulcanus MK4 microwave based hot water heater. There is also Chronomite Tankless, as well as Niagara Industries whole house tankless hot water heater. If you're browsing, Froogle produces no shortage.

With ever increasing energy costs, and given that traditional water heaters account for up to 20-30% of a homes energy use, tankless water heaters are becoming more attractive to homeowners.

The US Department of Energy has some information on tankless water heaters, including a section on whether the devices would work in your home. From the site:

For homes that use 41 gallons or less of hot water daily, demand water heaters can be 24%?34% more energy efficient than conventional storage tank water heaters. They can be 8%?14% more energy efficient for homes that use a lot of hot water?around 86 gallons per day. You can achieve even greater energy savings of 27%?50% if you install a demand water heater at each hot water outlet.

EcoSmart produces these unique, flueless fireplaces that can be installed essentially anywhere, as they do not require any sort of permanent fixture or fitting. The company makes many different 'shells' that house the actual burner unit which operates using a green fuel. From the site:

The EcoSmart Fire is fuelled by a renewable energy source called Denatured Ethanol. Ethanol is an absolute alcohol, produced by the fermentation of sugars originating from agricultural and forestry products; mainly sugarcane, potatoes, bananas, beetroot and recently from cereals such as wheat.

What are EcoSmart Fires? The EcoSmart Fire is a new, innovative style of open fireplace. It is environmentally friendly, aesthetically appealing, efficient and cost effective. The modular design means it is versatile enough to fit into a wide range of architectural environments. Whether installed in a loft, studio, apartment, terrace house or freestanding home, the EcoSmart Fire provides the 'primal' warmth and comfort of fire while enhancing the contemporary aesthetics of today's living environments. In essence, it is designed to be an inspiring, mobile 'piece of furniture'.

And yes, according to the FAQ, the fireplaces do indeed produce heat (about 13000BTU's worth).

In the original post about the Vulcanus MK4 microwave based water heater, the Pulsar Advanced Technologies website found in the Globe and Mail article turned out to be a work in progress. It looks as though the Pulsar Advanced Technologies people have another website, found here. Website number two has some actual information on the Vulcanus MK4, including a FAQ and a tiny picture, seen here. Apparently PAT, as I call them, are developing two models:

To begin with, we have two models whose function is to deliver two temperatures to several points of use. The first model has the capabilities to go from 35F-140F within seconds and supply multiple outlets concurrently. That is to say that this base model can service a bath/shower, and all other household faucets endlessly. The second model is equally fluid, but through a secondary thermostat control will deliver water at a higher temperature to service dishwashers and washing machines along with the various bathroom and kitchen amenities.

Stay tuned...

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.

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.

It's all about instant hot water these days. According to Canada's Globe and Mail, a company called Pulsar Advanced Technologies is about to announce a product that uses microwave technology to instantly heat hot water. According to the article, the Vulcanus MK4 "can heat water from 35 degrees Fahrenheit to 140 degrees Fahrenheit in seconds and can source multiple applications at once: showers, dishwasher, sink usages and more. The Vulcanus MK4 is the size of a stereo speaker with a sleek modern look, making it ideal for condos and apartments, while powerful enough to serve the needs of any size family." This is exciting news for anyone tired of being at the mercy of natural gas prices, not to mention those just looking to reduce their energy footprint.

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.

At only 4" thick, this gorgeous and unique in-wall gas fireplace is the perfect solution for those looking to add the warmth of a fireplace without losing valuable living space. The units are flueless and, according to the manufacturer, 100% efficient. This is due to the Firewall Flueless' lack of a heat-liberating chimney like those found in conventional gas fireplaces. There is also an added environmental benefit in that the warm air the unit exhausts is cleaner than the air it takes in!

So this guy combines an overhead projector and LCD projector panel, throws in a screen and for under $175, he's watching sweet, sweet big screen projected video. See also: Tom's Hardware version.

Quooker sells a nice looking product that produces instant boiling water, straight from the tap. The faucet draws the boiling water from an insulated tank mounted underneath the counter, where water is heated to 110°C. As the water flows from the faucet, it cools to 100°C. Quooker says that the unit's energy consumption is "next to nothing" in standby mode. I wonder if it would melt one of these.

Caution! The boiling water you are about to enjoy is hot...

If you live in a northern climate, you probably know all too well about escalating energy costs. Here is a list of some of the things you can do to minimize energy waste this season, as well as avoiding utility bill shock. These are pretty straight forward and frequently espoused, but dammit if I can help just one person out there... Sorry. Have any winter energy saving tips of your own?

Turn your hot water heater down. Most hot water heater's medium setting is fine for most uses. Check your dishwasher manual for minimum recommended temperatures just to be sure.

Consider a hot water heater blanket. Minor debate on the subject here.

Combat heat loss by caulking around doors and windows.

Install compact fluorescent light bulbs.

Change your furnace filter monthly. The less work your furnace has to do to push air throughout the house, the better.

Drop the temperature in your home to 68°F (20°C). Install a programmable thermostat and set it to a lower temperature at night as well as when you are out for longer periods of time.

Run foam insulation on the hot water pipe coming from your hot water heater. Foam insulation sells for pennies per foot.

If you suspect your furnace is due for maintenance, have it done as early in the season as possible. It's better to have the most efficiently running furnace for the entirety of the season to maximize energy savings.

Energy efficient appliances often qualify for government rebates and of course offer the monthly savings of a reduced energy bill.

Check your garage door for gaps and seal around it with weather stripping.

Install foam electrical outlet and light switch seals. This may seem futile, as each outlet only lets a small amount of heat escape, but when you consider the number of outlets and switches in the average home, the aggregate heat loss can be significant.

Turn off electrical devices you are not using. According to this site, a ball park figure you can use in calculating annual costs of electrical devices is one dollar per one watt (i.e. a 60w light bulb, left running year round, would cost around $60 dollars). Obviously not many things run year round, but for some, this rule of thumb would be easier to conceptualize than kw/h numbers. So, a single 150W PC, therefore, would run you about $150/yr.

Add insulation wherever needed - check your attic or between accessible walls.

Open the blinds or drapes as much as possible on sunny winter days - and at night, to keep that heat in the house, close them.

Use clear cling-wrap style window coverings available at most hardware stores. The plastic simply adheres to the window sill with the help of your hair dryer and the provided thin tape, forming an airtight seal.

Don't heat rooms that you don't use. Close off vents and tape them air-tight to prevent wasted heat.

Install reduced flow aerators in your shower. This will cut down on hot water usage.

Check out the DIY network's home energy audit to trace the source of heat loss in your home, without calling in the pros.

Stay warm.
