"    Radio-Controlled Lawnmower Built by: David O&amp;#039;Neil Greenacres, Florida     Here&amp;#039;s one we&amp;#039;ve all dreamed about on sticky, 95-degree days when the grass is starting to look too shaggy: a radio-controlled lawn mower. You don&amp;#039;t need to break a sweat to keep your lawn immaculate with this gadget around. In fact, you don&amp;#039;t even have to leave your house. David O&amp;#039;Neil took an ordinary 5 HP mower to use as a base for his project, stripped off the human controls, and added parts to control it with a remote. He used standard servos to control the shifting and gas, heavy-duty servos for steering the front wheels, and a centrifugal clutch to drive the rear wheels. Forget hiring the neighbor&amp;#039;s kid to mow your lawn - you&amp;#039;ll have way more fun planted in the shade with a cold one and the remote control for this contraption.    Battery Pack AC Adapter Built by: Clayton Westcott Cecil, Wisconsin     After dropping over $700 for cordless tools to help remodel a friend&amp;#039;s house, Clayton Westcott was dismayed to find that he could burn through all three of his battery packs in a day&amp;#039;s work, even while constantly charging the spares. Shelling out for cordless version of his brand new tools wasn&amp;#039;t an option, so he did what any Popular Mechanics reader would do: he improvised. Clayton built an AC to DC adapter into a battery pack, so that he could run his tools from an outlet whenever there was one nearby. Now he has a tool that he can run all day long off of wall current, and with the swap of a battery pack, the same tool can go with him wherever he goes, too.    Angled-Head Spray Bottle Built by: Raoul Drapeau Vienna, Virginia     Anyone who has used a spray bottle can attest to their finicky behavior when they&amp;#039;re less than full. Tilt your bottle just a little too far, and the dip tube is no longer submerged, leaving the spritzer gasping for air while you&amp;#039;re trying to clean a tilted window or a spot on the garage floor. Raoul Drapeau came up with an angled spray head to fix the problem. Users can twist the sprayer tip to shoot up, down or straight ahead, while the bottle and the liquid in it stay perfectly upright.    Dripless Squeegee Built by: Daniel Bastien Quebec, Canada     Just as gravity causes problems for the spray bottle, it also makes life difficult for the sprayer&amp;#039;s close companion - the squeegee. For instance, attempting to use the rubber blade of a squeegee on the inside glass of a windshield leaves a trail of cleaner all over the dash as the excess runs off. Daniel Bastien found his way around this little problem with non-vertical surfaces by adding absorbent material behind the blade, to soak up the excess before it runs off. You can find a video of Daniel showing off his invention on a mirror, as well as a copy of the patent he holds for it, here. "^^<http://www.w3.org/2001/XMLSchema#string>
