Everyone has had that moment that they turn the key and you don’t hear that satisfying noise that lets you know the car is up and running. Then you start to realize that you left your headlights on and your battery is completely dead. In those cases you have to grab the jumper cables and find someone to jump start your car. That means standing outside and hooking up the cables too, which is never fun in the dead of winter. Well now you can jump start your car all by yourself with a very small and easy to store gadget. The SelfCharge Auto Jumper hooks up inside of your car through your car’s cigarette lighter. After it’s hooked up it’ll take it less than ten minutes to get your car up and running. The device itself is rechargeable and can be recharged up to 500 different times. It will even work as a portable back up charger for cellphones, laptops and other smaller gadgets you carry around. It’s small enough to fit right under the passenger seat for easy storage and will cost you$44.95. If that’s a bit too much for you, there’s a version that also plugs in through the cigarette lighter that requires a second car to charge your car for$25.95.

Pocket projectors are all the rage now, the ability to use a projector the size of an iPod to display information on a wall is a godsend for the business set, who look to expand the ability to make presentations without having to travel with expensive projectors or having to customize their presentations to what equipment is available. But while getting more popular, projectors like the PICO and the Mili Pro - which can connect to an iPhone or iPod Touch - are still in their infancy. At it’s current state of technology, the MiLi Pro can project a 640×480 resolution image up to about 30 inches away before the lumens simply dissipate from distance. So, while it won’t project in very large meeting places, it can work for small, intimate gatherings where the presentation can be seen on a 40″ screen area.

This is one of those inventions most of the world really would probably wish it was never created. To be more specific everyone around the person that owns one of these will really really wish that it would just break. It can be reused time and time again, you’ll never need a refill for it like you would a normal air horn. Which means misery for all those around the person that owns it, up until they wise up and “accidentally” smash it. The horn blares just as loud as all air horns. In order to keep it going you refill it with the included pump or any bicycle pump or service station air pump. Each time you recharge it or fill it up using a pump it will get you 70 excessively loud blasts. The fun will just keep on coming. Not only is it meant for sports fans or those that just enjoy annoying others but for boaters as well. You can purchase the Ecoblaster Rechargeable Air Horn for $29.98 from Things You Never Knew Existed.

Some of you might be too young to remember when the Nintendo Entertainment System tried to sell the world the Power Glove. I guess they thought people would want to wear something on their arm and look like a cyborg, but it didn’t sell that well, even with the not-so-subliminal ad in the movie The Wizard. I believe that the Power Glove was one of the first attempts at motion control for video games, but motion control has made some leaps and bounds quite recently. A company known as AthroTronix has recently made some interesting motion control advancements with the Acceleglove. The Acceleglove isn’t designed for video game entertainment, but it is more for robotics. You can watch the YouTube video after the jump if you want to see a “hands-on” demonstration. As you might have seen, that freaky looking robot arm moved as the user flexed his fingers. It didn’t take a lot of flexing to make it move in its preprogrammed direction either. The Acceleglove works out-of-the-box, and comes with open source SDK so the user will be able to connect it to anything that he or she wants. Perhaps Nintendo needs to adopt the Acceleglove to make Power Glove 2.0. Maybe they should use it as a control for R.O.B., the Robot Operating Buddy from the NES Deluxe Set.

You never quite know when you might need to summon help, and since nobody seems to carry a magic lamp around these days that calls forth a slumbering genie after a few rubs, the next best thing would be the One Touch 911 Dialer. This is the pendant that calls a 911 operator with one press of a button, helping users sustain independence and mobility. Requiring no contracts or monthly fees, and operating over your existing phone line, a single push of the cordless pendant phone’s button immediately dials 911, letting you converse with emergency responders–not a distant third party. The pendant comes with a lanyard and belt clip, so it’s always close at hand, and its 600′ range allows you to move freely around your home. A unique test function verbally informs you whether the system is within working range. Smaller than most cell phones, water resistant, and weighing a mere 6 oz., the pendant is powered for one year by one AAA battery. The base unit will plug into the pone jack and AC, and you can bring home the One Touch 911 Dialer for $199.95.
