Most DIY digital picture frame howtos people post on the net go the 'dismantle an old laptop' route. As this site notes, the scavenged laptop approach has a couple of drawbacks:

All of them involved taking the laptop apart completely and generally rendering it useless for any other activity. The screens were also smaller than I wanted - equivalent to an 8"x12" photo, and varied considerably in contrast, brightness, and general image quality.

For my project, I wanted a desktop quality LCD screen of a size equivalent to an 11"x14" photograph. I also wanted professional quality matting and framing.

So, the author opted to use an old LCD monitor along with a hidden laptop. The trick is using two holes in the wall; an upper and a lower. The VGA and monitor power cable is fed through the upper hole and fished out through the lower hole, which is where the laptop sits, still accessible for maintenance and whatnot, but, in the author's case, hidden by a piano and usually controlled wirelessly.

The New York Times real estate section has an interesting article entitled "Making Every Pixel Count", which is about the importance of properly photographing your home for online real estate sites.

From the article:

When selling properties online, agents and Web designers say that the pictures buyers see of houses and apartments for sale are often the first - and sometimes the only - chance for a seller to make a good impression. Less-than-flattering pictures can turn buyers off and lead to lonely open houses.

So why is this so important? Well, some stats, from the piece:

Eighty percent of people across the country who bought a new home last year used the Internet while house hunting, and they rated photographs as the most useful tool in their search, according to a survey of buyers and sellers by the National Association of Realtors. The survey also found that 24 percent of home buyers got their first glimpses of their new homes on the Web, up from a mere 2 percent in 1997.

And let's face it, this number is probably going to continue to tend upward. If you've ever searched for a house or apartment online, you've probably been surprised and/or frustrated at the lack of pictures some listers provide. As many people will tell you, all the details in the world are still taken with a grain of salt when pictures aren't provided. Unless listers are trying to hide something, why not give web searchers what they want?

And although the mere act of posting pictures is crucial to attracting web-savvy prospects nowadays, the variance in the quality of the pictures can change the buyer's impression drastically. Be sure to see the audio slideshow that accompanies the article for examples of this.

If you've got an old, broken, space-eating gas lawn mower, you may be interested in resurrecting it and converting it into an eco-friendly solar charged model, provided you don't mind having it look a little Frankenstein.

This how-to walks you through the process of modifying a mower as well as creating the solar panel/charging station that provides the power. The mower does take a while to charge up (40 hours by the authors calculations, assuming a half-charged battery), but since most lawns don't require mowings of any greater frequency than that (or anywhere near that, one would hope), the solar solution seems like a perfect fit for the task.

The author provides a lot of detail, including a couple of schematics and a parts and costs table. The final price tag was $699, with the bulk of the cost going towards the motor ($312), solar panel ($120) and battery ($90).

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.

Powercast is a Start-up out of Pennsylvania that has come up with a way to wirelessly transmit power to electronic devices. According to this article on CNN, the technology uses radio frequency and has a range of about 3 feet, making it suitable for charging mobile phones on desks or keeping wireless mice and keyboards charged. Thanks to the tiny receiver chip, electronics manufacturers can implement the technology into almost any device.

Powercast won CNET's Best in Show for Emerging Tech at the 2007 Consumer Electronic Show, and they describe the technology thusly:

While it's presented as wireless power, Powercast isn't just a replacement for a universal charger. Instead, it's meant to either continuously charge a battery or replace the need for them altogether.
It works like this: a transmitter can be placed anywhere--in a lamp, for example, that is plugged into the wall and sits on a table. The transmitter in the lamp sends out a continuous, low RF signal. Anything with either AA or AAA batteries set within its range--and equipped with a Powercast receiver, which is the size of your fingernail--will be continuously charged.

The first Powercast devices will be hitting the market in 2007, according to the Powercast website.

If you've got a wireless network at home, you may want to check out this page from Microsoft that lists a bunch of things you can do to improve your WiFi network. Tips range from the obvious, such as removing obstructions and placing your wireless router in a central location, to the not so obvious, like advice about swapping out your router's antenna:

The antennas supplied with your router are designed to be omni-directional, meaning they broadcast in all directions around the router. If your router is near an outside wall, half of the wireless signals will be sent outside your home, and much of your router's power will be wasted. Most routers don't allow you to increase the power output, but you can make better use of the power. Upgrade to a hi-gain antenna that focuses the wireless signals only one direction. You can aim the signal in the direction you need it most.

and also changing the router's wireless channel:

Wireless routers can broadcast on several different channels, similar to the way radio stations use different channels. In the United States and Canada, these channels are 1, 6, and 11. Just like you'll sometimes hear interference on one radio station while another is perfectly clear, sometimes one wireless channel is clearer than others. Try changing your wireless router's channel through your router's configuration page to see if your signal strength improves. You don't need to change your computer's configuration, because it'll automatically detect the new channel.

Check out the rest of the tips to ensure your wireless network is running at it's optimum level.

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.

This creative tree of knowledge bookshelf by Italian designer Matteo Casarosa would fit right in to a children's bed or playroom. It's not clear as to whether the bookshelf is weighted down or supported in some manner, because if not, it looks like one would have to be careful not to place too many books on one side or the other, causing the shelf to tip. It's probably not an issue - just something to think about, as no one wants a branch across the noggin.

Here's a nice doormat that both welcomes guests and, later, bids them a coarse adieu. The designers of this clever mat have been able to massage and manipulate a font in such a way so as to create a readable message from both right-side-up and upside-down orientations. Upon arrival, the mat offers a welcoming "Come in", while departing guests are left to deal with the blunt "Go away" parting shot.

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.
