We’ve already seen that LEGO modeler Nick Jensen not only loves Halo but is very good with expressing that love in the medium of life-size models of weaponry. Now, he turns his attention to his favorite gun in the Halo games: The M45 Tactical Shotgun. His model, in addition to being human-sized, has a working trigger, moving slide, and a mechanism to eject LEGO ammo “shells.” See more of this impressive build, after the break.

As a sterling reminder that it’s the little things in life that matter comes this recent video from Norwegian outdoor sports enthusiast and freelance journalist Aleksander Gamme. For three months through 2011 and 2012, Gamme embarked on a solo cross-country ski trip to the South Pole and back. After 86 days of travel, a few days from the end of his return trip, he came across a cache of supplies he’d left while heading inland. What he’d forgotten was the chocolate and cheese doodles inside.

We’ve often discussed the trials and tribulations of beard ownership on Geekosystem, but what if you don’t have a beard? What if you’re a man or woman that wants to stay clean shaven, but is only interested in spending a dollar a month? Then friend, the Dollar Shave Club is here. Their claim: For a dollar a month, they’ll send you a high-quality, no frills razor blades. Sounds like a deal, and the only thing the Internet loves more than a good deal is a clever commercial. Fortunately, they have that too. See it, after the break.

The modern business card isn’t just about communicating information, but saying something about yourself and nothing says “motivated self starter” like a business card that is also a siege weapon. That’s the idea behind this trebuchet business card from mechanical engineer and business card manufacturer Bryce Bell. Simply fold, add 16 pennies as counterweights, and launch a paper clip some 10 feet. It’s surprisingly functional and remarkably accurate, though you’ll probably have to explain what it is to every single person you give it to.

Fishing in a kayak half a mile off the coast of Sarasota, Florida a man was greeted with a surprising guest swimming up to his boat, Barney the dog. The fisherman quickly reeled in his fishing line once he saw the dog — something I’m not sure if I would be quick enough to realize to do — and pulled Barney into his kayak. He dried the dog off and headed for shore, and during this time, Barney was perched on the back of kayak, a very small space, too afraid to move, clearly traumatized in some way. Obviously, small dogs don’t regularly end up half a mile out to sea, and it was apparent by that and the way the little guy was acting that he was involved in something unfortunate. It turned out Barney was involved in a deadly DUI crash; he was out for a jog with his owner, and a drunk driver struck and killed her not too long before the dog fled to sea. Fortunately, the story doesn’t end badly for poor Barney.

In an interview with New Scientist, Stephen Hawking was asked what he thought about most during the day. In a classic, age-old form, he replied, “Women. They are a complete mystery to me.” Possibly even more amusing, he wasn’t making the fairly standard joke — he was serious. A man who literally wrote the book on something as complex as Time doesn’t understand women.

At a recent concert in New Zealand, the Foo Fighters rocked so hard that it caused geological tremors similar to those of an actual earthquake. New Zealand’s GeoNet blog reports that two seismic stations outside the stadium no more than 2 kilometers away detected a “strong low frequency” of tremors during the time of the concert, with the strength of the tremors corresponding to the highs and lows of the music. Hilariously, the strength of the levels record were consistent with volcanic activity.

That’s right, Foo Fighter fans, your band rocks that hard.

Here’s the best use of $348,000 you’ll hear today: Using it to construct a pair of 10-story tall Tesla Coils, the largest in the world, and use them to simulate the effects of lightning in a controlled environment. That’s the plan of Greg Leyh and the project he calls The Lightning Foundry which is currently seeking funding through Kickstarter. But in addition to the complete badassitude of the project, Leyh has science on the mind as well.

When eating a ridiculously spicy taco, it’s convenient to have a soothing beverage on hand to ease the burn. But what if that soothing beverage was on your head, and what if it was attached to a suite of sensors that worked together to determine how much you were reacting to the spicy food you just ate? Then you’re probably wearing the Nuclear Taco Sensor Helmet, presented by Lisbon’s altLab at this year’s CodeBits conference.

Of course, after they built the taco sensor hat, the only possible way to present it was by making a fake Japanese game show. See it, after the break.

You knew it was coming, so you’ve had plenty of time to brush up your résumé and apply for a job as an astronaut. Sure, it’s not the most glamorous job. You’ll only make between $67k-$141K, and to qualify you’ll have to posses over 1,000 hours of jet-flying experience, an advanced degree, and also be between 62 and 75 inches tall. The perks? You fly into space.

See the requirements and apply for the job, after the break.
