Print your own 30 round AR15 magazine

AR

Here’s a 30 round magazine for an AR15, made just in time to add to the national conversation over things that look scary.

This magazine is the product of Defense Distributed who have previously graced the front page of Hackaday with their 3D printed scary bang bang machine. While continuing to work on their WikiWeapon – a gun printable on a home-built 3D printer – the team decided they could subvert more obtuse gun laws by making their own high-capacity magazine.

The magazine is printed on an extremely expensive commercial 3D printer, but the team is working to make it printable on more affordable models. The prototype magazine survived unloading a full 30 rounds. Video demo of that after the break.

Also on Defense Distributed’s DEFCAD is a sound moderator for paintball and air guns. While the design isn’t yet finalized for those big scary assault weapons, it should be possible to modify it for the big guns.  One of their next projects is a stock, hopefully one that includes a hinge.

Beating a plowshare into an AK-47

[Boris] must have been a little bored over Thanksgiving. We’re guessing that’s the case; why else would he build an AK-47 out of a common garden shovel?

After buying an old shovel from an antique barn in Vermont, [Boris] cut off the handle an attached it to an old Bulgarian AK he had just lying around. The new stock proved to be very comfortable, and not wanting to waste the iron in the shovel head, decided to make an AK out of the remainder of his purchase.

After tossing the shovel head into the furnace and pounding it flat, [Boris] had a respectable piece of metal to construct an AK receiver from. A bit of plasma cutting, grinding, and drilling turned this former shovel into a future gun, and with the help of a blank barrel the shovel became an AK receiver that is twice as thick and twice as heavy as a ‘normal’ AK receiver. Yes, [Boris]‘s new gun is even more indestructible than a stock AK – something that really shouldn’t be possible.

In the end, [Boris] spent $2 on a shovel, $30 on a barrel, and $200 on a Romanian AK kit. The result is an actual, working gun that is legal for him to own (but not sell – see the comments for that discussion).

Can you believe this Portal gun was built from scratch?

This Portal gun will really make [aNoodleJMC's] costume pop this year. He actually built the video game weapon replica from scratch. It even includes some electronics to light it up blue or orange depending on which portal he’s planning to fire at an available flat surface.

There’s a lot of parts that went into the project, but by far our favorite one on the list is an acrylic toilet plunger. Its handle serves as a light pipe for the colored LEDs and can be seen above as a cloudy rod at the center of the clear barrel. A 4″ and 3″ PVC pipe helped to form the rest of the barrel, along with a 3″ clear acrylic pipe for the transparent areas. The bulbous parts of the body were sculpted from florist’s foam. Once he had all of the parts roughed out it’s obvious that [aNoodleJMC] spent a ton of time filling problem areas with Bondo, sanding everything smooth, and giving it a paint job he can be proud of. We hope he didn’t forget to include GLaDOS in the fun.

We actually just bought our Portal gun. But that’s because we had the big plans of adding the ability to levitate objects.

Automatic Airsoft Turret

airsoft-turret

[Valentin] wrote in to tell us about his automatic Airsoft turret. What it lacks in accuracy, it more than makes up for with sheer volume of fire. The pellet container is able to hold 500 6mm bbs, so make sure to get out of the way after this device is armed.

The device itself is a great example of physical hacking, harvesting parts from a motion sensor as well as a G35 gearbox from Airsoft gun. For physical rotation, it uses a reversing platform reminiscent of the way a useless machine works (see this [HAD] article for more useless machine info). Even if you’re not interested in building a turret, this machine employs some very interesting concepts, so it’s worth checking out.

When live action Team Fortress becomes a fad, maybe these will make an appearance. Until then, check out the video of this turret after the break, or check out the original article for more pictures and video! [Read more...]

3D printed guns, laws and regulations, and philosophical discussions on the nature of printed objects

For as long as they’ve been banded about, 3D printers were regarded as the path to a new economy, a method of distributed manufacturing, and a revolution for the current consumer culture. With every revolution, a few people need to get angry and the guys at Defense Distributed are doing their part to make that happen. They’re designing a handgun able to be printed on a hobbyist-level 3D printer

This isn’t the first time we’ve seen a 3D printable weapon; this 3D printed AR-15 lower receiver is the only part of an AR-15 that contains the ID markings and serial number. Legally, the AR lower is the gun, and requires a background check to purchase (with the footnote that this varies from state to state and country to country – long story short, the BATFE probably isn’t happy about a 3D printed AR lower). The one drawback of a 3D printed AR-15 lower is that every other part of the gun must be purchased elsewhere. This is where Defense Distributed comes in: they propose designing a gun that is 100% printable on a hobbist-level 3D printer such as a RepRap or Makerbot.

Right now, Defense Distributed is looking for funding to produce two gun designs. The first design, WikiWep A will serve as a research build, allowing Defense Distributed to answer a few questions on what can be built with a RepRap. WikiWep B will have moving parts for the firing action and very nearly all the parts will be printable on a RepRap or Makerbot.

In the video Defense Distributed put up for their now cancelled IndieGoGo campaign (available after the break), the guys talk about the distribution of a CAD file of completely 3D printable weapon being a threshold of a new economy where laws and regulations cease to apply. We’re not sure we agree with that statement; after all, anyone with some metal forming tools can build an excellent weapon to acquire another weapon, but we’re interested in seeing what governments and regulators will make of Defense Distributed’s project.

Controlling a spud gun with an Arduino

We’re a long way from the Aquanet-powered plastic pipe spud guns of our youth. [smirpab] over on the SpudFiles forum posted a work in progress of an amazing replica AS50 sniper rifle he’s building. This pneumatic cannon goes above and beyond any air-powered rifle we’ve seen with an Arduino that is able to switch between automatic, semi-automatic, and burst modes with an LCD display and a rate of fire control.

The mechanics of [smirpab]‘s build are fairly normal for this level of pneumatic gun; it shoots 6mm plastic pellets from a smooth bore barrel with using air compressed to about 10 bar (145 psi). The electronics is where this project really shines, with an Arduino controlling the mode of fire (auto, semi-auto, and a 3-round burst), and the number of rounds per second adjustable with a pot.

A very cool project, and looking at the CAD renders of what [smirpab] completed project will look like, we can’t wait to see this build finished. As always, this build comes with the standard Hackaday “you’ll put your eye out, kid” warning. You can check out a video of [smirpab]‘s piston after the break, along with a demo of the Arduino-powered control circuit going through all three firing modes.

Soldering from the hip

You can be the Sheriff around these parts, but only if you have a solder gun and holster to boot. [Mikasaurus'] latest build is certainly fun, even if it’s not so practical. We’re not giving up our Weller knock-off any time soon, but this quick-heat repackage will certainly be a conversation starter at your next Hackerspace event.

The business end of the build is taken from a cheap four-battery soldering iron. [Mike] separated each of the components, then grabbed a toy gun to see where each of them might fit. The batteries are just the right size to fit into the gun’s magazine. All he had to do to make that happen is add contacts to the gun and springs to the magazine. A momentary push switch was positioned behind the trigger and used to connect the battery pack to the solder tip.

After the break you’ll find a little over-the-top modeling, and some solder melting. This will go great with that 9mm Bluetooth headset you built. Just don’t stick the wrong one in your ear.
