Gadgets come in all shapes and sizes, so our editors have decided to compile a list of the world’s largest (?) for your enjoyment. Which ones are your favorites?

60-inch Subwoofer

For earth shattering bass you can’t beat this custom made 60-inch subwoofer which has the ability to produce SPL levels above 180 dB. This monster has ouput displacement comparable to 160+ ten-inch woofers!

The motor is capable of producing 6,000+ pounds of linear force, which is necessary when considering the very large surface area and displacement volume required to produce high SPL levels


NES Controller

Incredibly enough, the world’s largest functional NES controller cost only $400 to build and made its debut on G4’s Attack of the Show.

We mounted the small NES controller inside the big one and ran the regular NES controller cable out to the actual NES unit



You’ll find the world’s largest functional Blackberry at the Nextel store inside the Las Vegas Convention Center Monorail Station.

Say good-bye to Blackberry thumb and hello to Blackberry hand. Remember, what happens in Vegas, stays in Vegas



Brian Walker has created the world’s largest crossbow and codenamed it Project RUSH (Rapid Up Super High). This crossbow will boost a “rocket-propelled” craft 20 feet into the air. It’s currently awaiting FAA approval.

He plans to pull 10 gs as the carbon-fiber bowstring releases and sends his little spaceship-like vehicle soaring into the air while firing a jet turbine with 1350 pounds of thrust. He will be wearing a Russian space suit to help keep his innards in, and has hydrogen peroxide rockets to help slow his descent, but we can’t think his mother is very happy about this all the same



MacDailyNews managed to snap a picture of the world’s largest iPod — strangely powered by an iPod Shuffle — located in Columbus, Ohio.

Visitors walking down Third St. have been gawking at this thing for the past couple of days. The 25 ft. iPod is attached to the side of the Unizan Bank building across from the state house. Not only does it look like an iPod, but it actually plays music!. We chose some of our favorite local musicians that had submitted songs to the online jukebox and we added them to the ipod playlist


3-D Display

Engineering students at the Delft University of Technology (TU Delft) have created the world’s largest 3-D display, using a matrix of 8,000 LEDs and lots of ping pong balls. It measures 8 x 4 x 2 m and was created in celebration of the 100th anniversary of “Electrotechnische Vereeniging” (ETV). Video of someone playing Snake here.

Tetris Game

Not technically a gadget, but still interesting none the less. This giant Tetris game was created using “eleven custom-built circuit boards, a twelve-story data network, a personal computer running Linux, a radio-frequency video game controller, and over 10,000 Christmas lights”. It took over five months of planning and can be seen off Interstate 95 in Rhode Island. [Source]

HD Screen

At 50 feet high and 137 feet across, this HD screen by Daktronics is the largest of its kind — built inside Miami Dolphins stadium. It has an incredible 145.83 foot diagonal, which makes it a 1,750-inch display. [Source]


One of the largest CPU fans ever made, Zalman’s CNPS9500 LED needs 1400W of power and “starter cartridges” to even start running. This 100% copper fan measures a hefty 85(L) X 112(W) X 125(H)mm and weighs in at 530g. Its compatible with Intel/AMD Processors and Socket 775/578/754/939/940 motherboards. British Aerospace wind tunnel engineers aerodynamically optimized this fan with a “tunnel” design for maximum cooling efficiency.[Source]
