Wireless Sun/Moon Weather Station

Gardeners, hikers, beach combers, farmers, sailors, skiers, daily commuters and anyone who needs to keep an eye on the weather and temperatures indoors and out will love this wireless weather station from La Crosse Technology. With 15 forecast icons, the station makes it easy to plan for that outdoor barbecue, beach outing, or ski day, helping you decide what to wear and when to schedule.
With plenty of versatile features, the unit displays sunrise/sunset and moon phases for 99 U.S. and Canadian cities. A remote sensor helps you monitor outdoor temperatures and the main console displays temperatures and humidity levels inside. The remote sensor works from up to 330 feet away for monitoring temperatures and humidity levels in the greenhouse, shop, and garage. It works great indoors too, helping monitor temperatures in the baby's room, music room, and near plumbing you don't want to freeze up. The main console receives data from up to 3 remote locations with the purchase of additional sensors. A great way to help kids dress for the weather, the weather station's Oscar Outlook icon is always dressed appropriately for weather ahead, with outfits ranging from swimming trunks to a coat, hat and scarf, and other weather-themed accessories in tote, such as a beach chair, an umbrella, or a snow man.
The station's precision clock receives signals from the U.S. Atomic Clock, automatically setting itself to exact time accurate to the second. A manual override setting lets you set date and time yourself for areas where Daylight Savings Time doesn't apply (otherwise the handy unit sets itself for DST, too). A large button lets you toggle between an array of time and weather displays. A flip out table stand sets up quickly on counter, windowsill, or desk, or the unit hangs easily from any wall in the home or office. This weather station is compatible with La Crosse Technology TX29U-IT 915 MHz Wireless Temperature Sensor.

Linksys WRT54G2 Wireless-G Broadband Router

The Linksys Wireless-G Broadband Router is really three devices in one box. First, there's the Wireless Access Point, which lets you connect both screaming fast Wireless-G (802.11g at 54Mbps) and Wireless-B (802.11b at 11Mbps) devices to the network. There's also a built-in 4-port full-duplex 10/100 switch to connect your wired-Ethernet devices together. Connect four PCs directly, or attach more hubs and switches to create as big a network as you need. Finally, the router function ties it all together and lets your whole network share a high-speed cable or DSL Internet connection.
Once your computers are connected to the router and the Internet, they can communicate with each other too, sharing resources and files. All your computers can print on a shared printer connected anywhere in the house. And your computers can share all kinds of files--music, digital pictures, and documents. Keep all your digital music on one computer, and listen to it anywhere in the house. Organize all of your family's digital pictures in one place, to simplify finding the ones you want, and easing backup to CD-R. Utilize extra free space on one computer when another's hard drive starts to fill up.

The new Wi-Fi Protected Setup feature makes it easy to configure your wireless devices. Just push the button on the router and on your other Wi-Fi Protected Setup-enabled wireless device to automatically create a WPA2 connection that protects your data and privacy with up to 256-bit industrial-strength encryption. The router can serve as a DHCP Server, has a powerful SPI firewall to protect your PCs against intruders and most known Internet attacks, supports VPN pass-through, and can be configured to filter internal users' access to the Internet. Advanced configuration is a snap with the web browser-based interface.

With the Linksys Wireless-G Broadband Router at the center of your home or office network, you can share a high-speed Internet connection, files, printers, and multi-player games with flexibility, speed, security and simplicity.
