laser shotgun

These are three words that should never appear together. Yet here we are thanks to YouTuber styropyro. He writes:

The output of this laser is complete insanity, and is made up of 8 parallel 5W laser beams totaling to 40W. The parallel beams are manipulated with lenses, sort of like how a choke modifies the spread of a shotgun blast.

The massive diode array is powered by a huge lithium polymer battery pack (capable up dumping 250A) and the laser array is regulated by a whopping 24 LM317 drivers.

See what it can do in the video after the break…

Don’t hire the Doof Warrior to play a luau.

Make’s Caleb Kraft is responsible for this ridiculous flamethrower ukulele, and you can see it in action in the video after the break…

bb8

From the moment he was first seen in the trailer for Star Wars: The Force Awakens, BB-8 has captured many an imagination. Having been there for his first reveal on stage at Star Wars Celebration, I can tell you that he’s a very cool, very real little ball of awesome and everyone wanted to know how Lucasfilm built him.

While there aren’t any official guides on how to make your own BB-8, more than one person has tried to create their own. This super extensive video guide by prop and robot builder James Burton of XRobots.co.uk will give you the best information yet on how to make one yourself.

If you do make one, can you make an extra for me?

Capture

This propane rifle was built with just a few simple components, but the firing effect is awesome to watch. All it required was a self-igniting propane torch and some 7/8 inner diameter tubing. The Backyard Scientist went a step further however and colored the flame green with boric acid. Adding a little powdered charcoal resulted in an orange flame with sparks.

See the video of the gun in action after the break.

Kelsey Kronmiller is a gamer who also happens to love her pet fish. So, she took it upon herself to construct an epic, gaming-themed fish tank that we first spotted in 2014.

Now we have a lot more information about how it was made.

lego-glue-gun-3d-printer

This isn’t your mama’s crafting tool any longer. This is a super MacGyvered 3D doodler created by Industrial design student Vimal Patel.

The idea started from a university project where he was challenged to use biodegradable 3D printing filament (monomateriality) to replace the functionality of multimaterial products. Products like helmets, for example, use multiple materials like foam, plastic, adhesives, and paint which cannot be recycled easily. A helmet made of a single material would go a long way in overcoming this problem. Plus, it would be a lot cheaper to produce.

Experimenting with traditional 3D printers, Patel printed layer upon layer to resolve the hardness issue of the filament, but then the flexibility became compromised. Realizing the answer to both issues would be to “extrude material along a path in multiple axes”, he took the next, uh…logical step and fabricated a handheld printer out of LEGO and attached it to a glue gun. Viola, a handheld printer that layers on all axes.

This is just pure genius. Check out the video below showing the build and the printing in action.

scare-owl

Imagine that you’re a squirrel, browsing a terrace garden for a snack when when suddenly this frighteningly disfigured owl from hell shoots you in the face with water. You’ve just been served by the Squirrelinator 2000.

After several unsuccessful attempts to rid his garden of the furry buggers, Redditor metroSFVogange decided to go nuclear. He installed an old IP camera in a garden owl (discounted because of the nightmarish exposed eye socket. He plans on adding a Terminator red eye soon) and wired an electric squirt gun to it. So when the squirrels sneak in, the motion detection on the camera triggers the squirt gun to fire. There’s even a solar-powered spinning prop to make it more menacing. But the best part is that the device takes pictures of its victims.

Check out the photos from the build and a recent squirrel encounter after the break…

These little crocheted Teenage Mutant Ninja Turtles might even be better than action figures (they’re certainly cuter). Plus, the pattern you need to make them yourself is available as a free download.

Secret-Mines-of-Moria-Door

Imagine having a secret door in your home that only appears with the touch of your hand. Redditor Eclipse_007 built a secret entrance to his home movie theater inspired by the Door of Durin from Lord of the Rings. Although the famous doorway to the Mines of Moria opened with a spoken word, he’s working on that.

First he built a box out of plywood to fit the doorway and lined the inside with a string of super bright LED lights. Then using plexi-glass covered in vinyl, he hand-drew and cut out the designs to replicate the markings from the LotR door. After painting, the installed door looks more like something from the side of a rock, which ultimately gives a much more desirable look.

And finally, he hand-carved the most important part, the incantation which reads,  “Ennyn Durin Aran Moria. Pedo Mellon a Minno. Im Narvi hain echant. Celebrimbor o Eregion teithant i thiw hin.” Translated it means “The Doors of Durin, Lord of Moria. Speak, friend, and enter. I, Narvi, made them. Celebrimbor of Hollin drew these signs.”

Check out the incredible work and completed door in action after the break.

rc tie interceptor

The rebels got their RC Millennium Falcon, and now the Empire has a version based on the TIE Interceptor.

Both were created by hobbyist Oliver C who notes that the TIE version took about 15 hours to design and “at least as many” to get it flying properly. There was also a mishap or two along the way, with shattered propellers embedding splinters of carbon in the walls of his garage.

Check out a video of the RC TIE Interceptor in action after the break…
