" Happy Camper The quest to bring the comforts of the great indoors to the great outdoors has spawned a wide variety of gargantuan RVs and trailers. But fuel doesn&amp;#039;t grow on trees, and maneuvering through traffic and narrow roads is no picnic in a Winnebago the size of a Greyhound. These days, it&amp;#039;s refreshing to see anything on the road that makes efficient use of its own space. Which brings us to the T@B ($8843 to $15,213, depending on exterior and options), a lightweight &amp;#039;60s-retro teardrop trailer that can be accessorized with red, orange, yellow or silver trim. At 6 ft. 7 in. wide x 7 ft. 9 in. high, it&amp;#039;s small enough to fit in your garage and big enough for you to stand up (okay, crouch) in. Should you wish to lie down, the couch seating can turn into a queen-size bed. You can even tow the T@B&amp;#039;s 1346 pounds with a Toyota Corolla. Its period-piece exterior doesn&amp;#039;t mean you can&amp;#039;t trick out the trailer with air conditioning, porta-potty and mini fridge--somehow, the T@B makes room.--Wes Meltzer Wish List  Can You Hear Me Now?

Toshiba has long supplied hard drives for Apple&amp;#039;s music players, and that makes Toshiba&amp;#039;s Gigabeat (available in 10GB, 20GB, 40GB and 60GB) a natural contender. It has a larger color screen and sells for less than Apple&amp;#039;s color machines (if you shop around).

A: I designed a wheelbarrow with a ball for a wheel called the Ballbarrow. Unlike conventional wheelbarrows, it didn&amp;#039;t sink in soft earth. 2 Q: Your new vacuum works by using an articulated joint around a rolling ball. What&amp;#039;s with the balls? A: It&amp;#039;s a very efficient shape. With an ordinary vacuum, you have to go back and forth to steer around an object. Our vacuum moves around the ball, so you can steer without all the extra movement. 3 Q: What is life like for the modern basement inventor? A: So many patents have been filed that it&amp;#039;s hard to be completely original. But I still think there&amp;#039;s room for the basement inventor, because he can take risks that big companies can&amp;#039;t. Backyard Lab Thrilla On The Grilla Some swear by gas, others by charcoal. We tested both--flamo a flamo. BY LOGAN WARD SPARKY (gas) VS. SMOKY (charcoal) Since time immemorial--or at least 1960, when Modern Home Products invented the gas grill--men have gone Hatfield and McCoy over the best way to cook dinner in the backyard. In the States, gas grills outsell charcoal models 2 to 1. Still, purists swear by the ancient ritual of laying a cooking fire and the smoky flavor that comes from searing meat over glowing coals. To douse the heated debate, we staged a cook-off between gas and charcoal. To help us, we enlisted the services of one cow, one pig, two chickens and a couple of cans of beer.  TEST ONE: BURGERS Before we can get down to business, Smoky needs a 40-minute warmup, while Sparky is raring to cook after less than 10 minutes. When flare-ups from both camps threaten to burn the beef, we drop a lid on Smoky and choke down his airflow by closing vents. Quenching Sparky&amp;#039;s flames is as simple as rotating burner dials from high to low. In the end, Sparky&amp;#039;s patties are better-looking (wide stainless grates leave near-perfect sear marks) and slightly juicier, but when it comes to flavor, the panel of hungry carnivores (aka &amp;quot;the judges&amp;quot;) rules unanimously in favor of Smoky.  TEST TWO: BEER-CAN CHICKEN Sparky&amp;#039;s hen, with its plump brown breasts, wins the beauty contest. But the charcoal-cooked chicken, coated in a fine layer of ash, is both juicier and smokier-tasting, probably due to the dwindling charcoal temperatures that dipped below even the &amp;quot;low&amp;quot; setting of the gas grill.  TEST THREE: PORK SHOULDER Last up, the grilling marathon-5 hours of slow-cooking a bowling-ball-size hunk of hog. We season two 8-pound picnic shoulders, lay them above drip pans with low, indirect heat rising on either side, and wait. We add charcoal once. The charcoal-cooked pork turns out tastier and juicier, and falls away from the hock with the prod of a fork. The gas-cooked shoulder, though russet-colored and savory, is tougher, slicing more like a roasted turkey. THE WINNER The gas grill is more convenient, cleaner and turns out better-looking dishes. The same could be said for the kitchen. Which leads to the deeper question: Why grill? If it&amp;#039;s to break the workaday monotony with a nod to our hunter-gatherer past, then the dirtier, smokier experience of the charcoal grill--not to mention its superior flavor--wins spatulas down. Did you know? The first charcoal briquettes were made from wood scraps left over from Model T production. The charcoal plant Henry Ford built later became the Kingsford Co., which today converts more than 1 million tons of wood scraps into briquettes each year. Off The Shelf Class Project We locked a team of teenage geniuses in a room for 6 hours with RadioShack&amp;#039;s Vex robotics kit. Here&amp;#039;s what came out. BY JILL DAVIS This year, 2Train Robotics, a student team from the South Bronx&amp;#039;s Morris High School Campus, snagged the top prize in the New York City regional FIRST Robotics Competition. The team&amp;#039;s 130-pound machine, dubbed 2Spicy, took six weeks and $3500 to build. So when we decided to test the limits of RadioShack&amp;#039;s Vex Robotics System, a do-it-yourself kit with 500-plus parts and a comparatively puny price tag of $299, we gave the kids at 2Train a call. The assignment? Build a freakin&amp;#039; cool machine--and do it fast. After 6 hours, the result was 2Spicy Jr. (above), a robot with an articulating crane designed to pick up the receiver of a standard telephone. A separate articulating finger dials numbers--in this case, 911. &amp;quot;We wanted to help the handicapped,&amp;quot; says sophomore Livio Guerrero. Admittedly, 2Train felt constrained by the limitation of a mere 500 parts. The gear ratios didn&amp;#039;t provide enough torque to build a robot that could perform more complex tasks, such as climbing over walls. However, if the customer wants more functionality, RadioShack is more than happy to sell accessories. The retailer stocks several kits that allow users to preprogram their robot, coordinate it with other bots, or use multiple remote controls for different functions on one robot. Robot novices will appreciate the kit&amp;#039;s hefty inventor&amp;#039;s manual that includes clear explanations of analog versus digital sensors, gear systems and the preprogrammed microcontroller. And for parents concerned about putting keps nuts and radio transmitters in the hands of curious kids, fear not: The guide also warns against licking batteries or inserting sensors into nostrils.   STUDENT REVIEW COMPONENTS/PRICE &amp;quot;When I saw all those parts, so many ideas for robots came into my head, like ones that smash cans or flip items into the air.&amp;quot; --Jon Tarkenton, 15 &amp;quot;If it were just a toy, it would seem like a lot of money, but you can take it apart and put it back together again and again.&amp;quot; --Kristian Bruno, 16 EASE OF USE &amp;quot;Actually building the robot is supereasy, because all the plates are predrilled, and all the parts are designed to fit together.&amp;quot; --Lori Gonzalez, 17 &amp;quot;Concepts such as torque and gear ratios can be difficult to grasp, but the instruction manual explains them really clearly.&amp;quot; --Kristian Bruno LIMITATIONS &amp;quot;We wanted to build a robot that flipped over an obstacle, but we needed more servos, more motors, more gears and more wheels. Our idea had to be based on what was in the kit.&amp;quot; --Livio Guerrero, 16 Buying Guide High-Tech Roadshow These portable devices let you bring along everything for work and play, without getting weighed down.  LIGHTWEIGHT LAPTOP With its mini keyboard and 7-in. screen, the 2-pound Toshiba Libretto U100 looks as if it were left in the dryer too long.

I had the chance when I tested the Olympus m:robe 500i, a 20GB machine with a 3.7-in. touchscreen display that is a music player, 1.2-megapixel camera and photo viewer. Verdict? Great with tunes and the screen is crisp, but colors are weak and controls are a chore--the touchscreen is your only interface.

Clear Photo transmissive/reflective LCD screen is likewise impressive in preventing reflective light from washing out the image. $500; www.sonystyle.com  SHRUNKEN STORAGE There&amp;#039;s usually nothing glamorous about hard drives, but a 100GB drive that measures only 5.1 x 2.9 x 0.5 in. can make heads turn. That&amp;#039;s 21 DVDs&amp;#039; worth of capacity in a drive that fits in a shirt pocket. It requires only a USB cable for both power and data. It spins at just 4200 rpm, but in our tests we were able to stream smooth video from it to our PC. $299; www.iomega.com  BABY BOOMERS At some point in the past 20 years, the personal music player killed the once-mighty boombox, and portable tunes got a little less social in the process. But now a minispeaker trend is gathering steam. Our favorite palm-size set is Pacific Rim&amp;#039;s Cube Travel Speakers. These cheap, self-powered speakers sound impressive, fold up when not in use and work with nearly any player. $40; www.pacrimtechnologies.com WHO&amp;#039;S GOT GAME?
