Hacker Maketh Kingsman Umbrella

Yes! Someone made the Kingman umbrella and yes it can shoot and yes it has a display on the inside. [James Hobson] just put up a video on YouTube for this excellent project detailing the process that went into creating this live working prop and it is amazing.

The build starts with finding a rugged umbrella and was tested by standing on it as well as decimating a few household objects. Compress CO2 cartridges provide the fuel for propelling blow darts as well as other non-lethal forms of ammunition. The coolest part of the project is the screen inside the …read more

Wield The Power of Molten Metal

[TheBackyardScientist] at it again with another super villain-esque demonstration of gadgetry: a liquid metal squirt gun.

The squirt gun has a compressed air tank like most others — more on that later — but to fire its primary ammunition, a nozzle that connects directly to an air compressor is needed. Again, like most guns of this nature, air is forced into the gun’s reservoir, displacing the pewter and expelling it out the gun’s barrel. Yes, pewter.

Working around the heat tolerances of thread seal tape, pewter has a low enough melting point that an airtight system is preserved — plus …read more

Cardboard and Paper Gun Shows Off Clever Construction

This project by [blackfish] shows off a cardboard lookalike of an MP5 that loads from a working magazine, has a functional charging handle, and flings paper projectiles with at least enough accuracy to plink some red party cups. It was made entirely from corrugated cardboard, paper, rubber bands, and toothpicks.

In the video (embedded below) you can see some clever construction techniques. For example, using a cyanoacrylate adhesive to saturate areas of wood, cardboard, or paper to give them added strength and rigidity. The video is well-edited and worth a watch to see the whole process; [blackfish] even uses a …read more

Folding Mass Effect Pistol!

Video game props require a dedicated maker with a repertoire of skills to create. When those props are pulled from the Mass-Effect universe, a little more technological mastery is needed. Bringing those talents to bear,  [Optimistic Geometry] has built a motorized, folding M-3 Predator Pistol!

The gun was modeled in Fusion 360 and 3D printed on an Ultimaker 2 at the  MAKLab Glasgow. [Optimistic Geometry] felt constrained by the laws of our reality, so opted for the smaller firearm thinking it would be an appropriate entry-level challenge. I’m sure you can guess how that went.

There wound up being three …read more

Tear Gun Transmutes Emotions Into Firepower

Frustration is tough to deal with. When driven to the point of tears it’s sometimes a short step to lashing out irrationally. Focus in these situations helps, channeling your frustration into something useful. [Yi-Fei Chen] has done that — quite literally — by designing a gun that fires her shed tears.

The gun’s design manifested following a strenuous midterm presentation. Her insistent tutor drove her to tears as frustration clashed with the deep cultural values of her native Taiwan which prevented her from speaking up against authority.

A silicone cup resting against her cheek collects the tears which flow into …read more

Disposable Camera Coil Gun!

Some of the most enjoyable projects tend to have the terrible drawback of also having the most potential to cause bodily harm, like getting zapped by the capacitor when digging into a disposable camera. But often — if you’re careful — this curiosity pays off and you wind up learning how to make something cool like this coil gun from a camera flash’s capacitor. This handheld launches a small nail, and is packed in a handheld form factor with a light switch trigger.

[LabRatMatt] dispels any illusions of potential harm upfront and then repeatedly urges caution throughout his detailed guide. …read more

Weaponizing Elementary Science Experiments

[austiwawa] was playing around with one of those simple linear motors people build as friendly little science experiments. There’s an AA battery in the middle of a set of magnets. When you put it inside of a spring it zips around inside until you run out of spring or magic pixies in the battery.

Of course, the natural question arose, “How do I make it go fast!? Like fast!” After making explosion and woosh noises for a bit (like any good hacker would) he settled down and asked a more specific question. If I made the coil the barrel of …read more
