After moving into a new home in Knoxville , you should immediately replace its deadbolt locks.  It’s not just the home’s former residents that have the key, after all, but so might a relative, a friend, a neighbor, a dog-walker, and others.

You may call a locksmith for the job, but you can save some money if you can do-it-yourself.

In this detailed, 2-minute video, you’ll learn how to remove and replace a deadbolt lock using nothing but a Phillips screwdriver and a deadbolt from a hardware store.  It’s a simple project that requires little mechanical skill.

And one that can make your new home more safe.

You could call it the Ultimate Geek Gift for an iPhone-toting friend — or even for yourself. It’s a set of 16 coasters made to look like iPhone application icons.

Made by Brazilian firm Meninos, the coasters are constructed from sturdy, medium-density fiber plywood and are coated in vinyl.  They’re are roughly 3 1/2 inches square, washable, and feature non-skid, rubber bottoms.

Many of the most popular iPhone icons are included:

• Maps and Compass
• Camera and Photo Albums
• YouTube and iPod

The iPhone coasters sell for $59.99 plus shipping. Arrange them like your phone, or pin them on the wall.  Either way, they’ll be a functional conversation piece for your home, or the home of a friend.
