Think about the masses of AA batteries you go through every year. How many of them could have been reused with an easier method of recharging? Even though we already have plenty of gadgets we charge from our computer, USBCELL allows us to save some money too.

The USBCELL batteries charge right from a USB port on your computer, and are fully powered to provide 5 hours of constant battery usage. Then you just recharge them again. This helpful gadget would also reduce the amount of batteries in our landfills, which is just an environmental hazard waiting to happen. — Andrew Dobrow

Somethings we’ll never understand, but we learn to accept them as certainties. What is our geeky obsession with cool clocks and watches? We don’t have an answer for that question, but we do have incentive for you to join our excitement. The Four Cubes Clock is a snazzy tabletop timepiece consisting of…well, four cubes that display the time, two designated for the hour and two for the minutes.

The cubes are connected through a wire that allows the cubes to be switched up regularly, which would make for a pretty funny practical joke to play on the owner. The clock is powered by 3 AA batteries. At first, people would look at it and be all like “why does my good friend have random number cubes sitting on his desk?”. And then, common sense will strike and they’ll feel moronic. All that’s left to do is give yourself a pat on the back for your genius design habits.

This cool kit gives you everything you need to create your own four-legged, spider-like robot. The Joinmax Digital Quadruped Robot Kit packs in an intermediate level DIY project, with 8 servos for enough degrees of freedom to explore and experiment with the robots motion and gait. The only thing not included in the set that an amateur robotics builder would need to add is 5 AA batteries to get the little guy going. To assemble the robot all you need is a phillips head screw driver and you’ll have your very own built robot in under two hours, even for the novice builder. No glue is needed since each piece is form fit to match the other. The Quadruped also comes with illustrated instructions and is available for $230. It might not be enough to win you world domination, but it’s a start. — Andrew Dobrow

If you’ve ever wanted to take pictures that are 3D, the StereoVision 3D VuCam finally brings the dreamers a dream come true. Using a combination of binocular optics and two 3.1 MP cameras, the VuCam can take 3D pictures even from a distance, allowing an up close and personal realism to your photos.

The VuCam’s binocular optics magnify up to 8x with a 44mm objective lens. With the option of both auto and manual focus, you can add a hint of creative blurring or what have you to any of the 3D images you take. The images can also be downloaded directly onto your computer. Images can be saved to a removable flash memory card as well for you card reader fans. You can also preview your shot by glancing at the pop up LCD display.

Images will work on a 3D monitor or screen without glasses, and with glasses when not using a special 3D display. You can also print the images with anaglyph settings. The VuCam runs on 2 AA batteries, but sadly only compresses photos in JPEG. — Andrew Dobrow
