With the new X-Men movie coming out soon, [Colin Furze] decided to make some real working props from the movies — starting with some bloody brilliant fully functional and retractable Wolverine claws.
We’ve seen Wolverine claws before, even electrified Wolverine claws, but never have we seen anyone take them to the level [Colin] has. He didn’t just want realistic Wolverine claws. He didn’t just want claws that could deploy. He wanted realistic claws that could both deploy, and retract — fast! And he wanted them to branch out just like the real deal.
He started brainstorming different ways of doing this. Motors, springs, geared racks, cables, pneumatic cylinders… nothing really fit the bill. Pneumatic power seemed the best option for performance, but the problem is he’d need a 12″ cylinder to sit behind his claws — it’d completely ruin the look — one of his main criteria for the project.

As technology continues to advance, make-believe props and technology from movies are coming closer and closer to reality. [Patrick Priebe] has managed to put together a working Spiderman Webshooter with the help of electromagnets!
He’s built a tiny coil gun that puts out 100 Joules of energy using a 350V capacitor bank, which straps cleanly to his wrist over top of a Spiderman costume glove. It makes the classic high-pitched hum as it charges, and launches a small barbed brass arrow capable of skewering Styrofoam.
He didn’t stop there though! He’s created a handy little winch using a small high-powered brushless motor with an ESC. A weighted disk acts as a flywheel to increase the pulling power of the fishing line, and he’s built it on a pivot so when you launch it, the fishing line just slips off the end without resistance. To engage, you flip it back perpendicular to the line and turn on the motor.

Today we’re looking at a few fun hacks, although they are perhaps a bit ill-advised. What’s the craziest thing you could strap to a quadrotor? Rockets? Lasers? Turns out… they’ve both been done already.
First up is [Ramicaza’s] firework launching quadrotor. The drone is stabilized using the ArduPilot Mega 2.6, and it carries a pair of “rockets” which are ignited by a pair of steel elements. An ATtiny analyzes the auxiliary radio channel’s PWM signal which controls the relays that power the elements. He’s tested it high up in the sky, so he’s actually being pretty safe about it.
Next is [JLaservideo’s] laser quadrotor. He’s taken a RC controller of a cheap toy to add wireless capabilities to his Arduino Uno. He’s re-routed the original RC toy’s motor wires to an input on the Arduino which in turn activates a 5V relay that powers the 1W laser. It looks awesome thanks to the bright beam — we just really hope he’s wearing proper eye protection, as a laser of that power can do some serious damage to your retinas!
Stick around after the break to see both quadrotors in action!

We’ve seen quite a few automated paintball marker systems over the years. Generally it’s the same story – a motion detection system used to target and fire upon the opposing team, prowlers, spouses, etc. [Waterloo Labs] decided to take a slightly different approach, and create a system that intentionally misses its target. Paintball Picasso uses a pair of Tippmann A-5 paintball markers to draw an outline around the person in its sights. This is a rather safe project for [Waterloo Labs], considering their previous adventures in car surfing.
The Paintball Picasso system uses a webcam to capture an image of a willing test subject. Picasso then processes the image. The human outline is plotted on a 50×50 grid of paintball pixels. Then the real fun begins. Paintball Picasso uses a National Instruments myRIO to command two paintball markers to simultaneously fire. The markers are fitted with high torque R/C style servos for pan and tilt. At 10 rounds per second the markers quickly draw the human outline. The test subject walks away slightly splattered, but otherwise unscathed. With a matrix of 2500 points, [Waterloo Labs] has enough resolution to draw some basic logos.
We liked the mounting system [Waterloo Labs] created for the markers. Using a mix of 3D printed parts, Lego Tetrix, 80/20 aluminum extrusion, and ball bearings, they fashioned a mount that moved smoothly enough for R/C servos to actuate, yet was strong enough to withstand the kick of firing. We’d love to see the servos swapped for stepper motors and belt drives. While open loop, stepper motors would afford more accuracy and a longer life than PWM driven R/C servos.

There’s a huge price discrepancy between paintball pistols and paintball sniper rifles. So the [Fresh-Prints-of-3D] decided to print himself an sniper upgrade kit.
He started with the classic Tippman 98 Custom pistol , which is a tried and true industry standard when it comes to reliable paintball guns. Using Sketchup he designed a side loading hopper adapter, a fixed stock, a magazine adapter, various brackets, and even a bipod fore-grip. He then printed the parts out at his local hackerspace; Innovatrix Labs, which is in Northeastern Pennsylvania. A Portabee 3D printer was used for some of the first prototypes but the final parts were all printed on a large MendleMax2 which has a build area large enough for the entire fixed stock!
The best part? He’s only been using SketchUp for a few months. Once the design and build is completely finalized he might release it under a CC license.
It just goes to show that 3D printers are really breaking down various markets of overpriced plastic components — 3D printers only print trinkets? Pfft.
[Spider!]’s contribution to the pantheon of paintball markers is the SMAC: a unique revision to one of Airgun Design’s ever-popular Automags. We needed our tipster, [Russell] to provide some context on the Automag’s evolution, because the brand has served as a popular hacking platform for nearly 20 years. The most frequent is a “Pneumag” modification, which converts the original, fully-mechanical trigger pull into a version where the trigger actuates a pneumatic cylinder to fire the gun.
According to [Russell], the Pneumag’s trigger must completely release between each shot to properly recharge the firing chamber. Without a full release, the gun can load extra balls into the barrel and lead to gloppy consequences. Electronic controls solve this problem, but [Spider!] favored an analog solution that captured a “less is more” mentality over a pre-fab microcontroller board. He built the circuit around a 556 timer used as a delayed re-trigger, but with a few modifications.
Swing by [Spider!]’s forum post for additional details, a cluster of pictures and a bill of materials. Microcontroller alternatives? We’ve got you covered.
The people who go nuts over 3D printed guns are going to have a field day with this one. It’s a shotgun and ammo built entirely from items you can purchase after passing through airport security. Now look, obviously the type of folks who read Hackaday understand that security in any form is something of an illusion. House keys don’t keep people from breaking into your home. Encryption doesn’t keep the government from looking over your shoulder. And no level of security screening can eliminate every possible hazard. So let’s just enjoy this one for the fine act of hacking that it is.
[Evan Booth] put his mind to work on the items you can buy at the stores inside of an airport terminal. Above you can see the diagram of all the parts. The break action accepts a Red Bull can that acts as the cartridge for the shotgun (our calculations put this at just under 0.25 Gauge). The bottom of the can contains water separated from Lithium metal (from cellular phone accessories?) by a condom. When the nonet of 9V batteries are connected to the heating element from the hair dryer it melts a hole in the prophylactic, mixing the water with the metal causing a reaction that propels pocket change as the projectile. The video after the break shows that this does take a while… perhaps 10 seconds from the time the trigger is pulled. Oh, and you might not want to be holding the thing when it goes off. We’d say the firearm can barely contain the explosion.
If you like this (or were horrified by it) [Evan’s] got a whole collection of weapons built inside the airport terminal. For those that care, here’s a link to the most recent of 3D printed gun posts which we referenced earlier.
