The Pistol Splat was a very weak blaster built for children, designed to shoot toy-grade paintball-like ammunition. [Matt Yuan] recognised the potential of the single-shot design, though, and repurposed it as a powerful Nerf blaster.
The blaster is a simple spring-plunger design. Upon pulling the trigger, the spring drives the piston forward, shooting the ammunition out the barrel. As stock, the Pistol Splat featured an incredibly strong spring and an unrestricted barrel, giving it plenty of performance capability. With some finagling, it’s capable of shooting a Nerf dart at 100 feet per second in stock form.
[Matt] improved the blaster by removing its dry-fire protection spring, which consists of a second spring to resist the plunger’s motion. Modification also involved fitting a barrel sized to properly seal on the darts. These two mods boosted the dart velocity to 110 feet per second. Adding a spacer to ensure the spring fully drove the piston forward for its full travel further boosted the dart velocity to a mighty 145 feet per second.
It bears noting that serious Nerf blasters like these demand eye protection. Video after the break.

Remember the pistol controller for the original Atari 2600? No? Perhaps that’s because it never existed. But now that we’re living in the future, adding a pistol to the classic games of the 2600 is actually possible.
Possible, but not exactly easy. [Nick Bild]’s approach to the problem is based on machine vision, using an NVIDIA Xavier NX to run an Atari 2600 emulator. The game is projected on a wall, while a camera watches the game field. A toy pistol with a laser pointer attached to it blasts away at targets, while OpenCV is used to find the spots that have been hit by the laser. A Python program matches up the coordinates of the laser blasts with coordinates within the game, and then fires off a sequence of keyboard commands to fire the blasters in the game. Basically, the game plays itself based on where it sees the laser shots. You can check out the system in the video below.
[Nick Bild] had a busy weekend of hacking. This was the third project write-up he sent us, after his big-screen Arduboy build and his C64 smartwatch.

The modified Nerf scene used to be about getting the absolute maximum performance out of Hasbro’s off-the-shelf foam dart blasters. The community quickly found the limits of plastic parts made down to a price, and an underground market for heavier springs and CNC-machined upgrades sprung up. Eventually, however, the advent of 3D printing and cheaper home machine tools led to a rise in popularity of bespoke blasters. [Zach] has long advocated for their supremacy, and has made a long-range blaster aimed at newcomers to the hobby. (Video, embedded below.)
The blaster is built around the popular Caliburn spring-powered design, originally created by [Captain Slug]. Modifications by [Zach] involve a longer barrel, relocated side-feeding magazine port, and other modifications designed to suit the long-range sniping role. There’s even a special “rifled” stabiliser on the end designed to reduce the effects of muzzle blast from disturbing the dart as it leaves the barrel.
It’s a design that very much builds on the efforts of the wider Nerf community, and is all the better for it. [Zach] has shared files and links to parts bundles to help get enterprising builders up and running with a minimum of fuss. We’d love to take the long blaster out for a round or three ourselves – it may just be time to fire up the 3D printer!

If ever there was a quintessential weapon of science fiction, it would have to be the ray gun. [lonesoulsurfer] built this one-of-a-kind stunner from his impressive collection of junk. It’s centered around a vintage Bakelite soldering gun, a vacuum tube, and a portable stove burner, all of which contribute to the fantastic mid-century look.
Inside is a slightly modified version of a ray gun sound effects circuit from MAKE: that squeezes square waves from a lo-fi synth builder’s favorite IC, the 40106 hex inverting Schmitt trigger. [lonesoulsurfer] was able to reuse the soldering gun’s trigger to start the pew-pew-pew, and he can adjust the death ray’s output with potentiometers. The gun is powered by an old cell phone battery and a combo Li-ion charger/step-up module from the world’s largest virtual auction house. Blast past the break to watch the build video.
If one little green LED isn’t enough for you, maybe you’d prefer this light painting gun.

[CutTransformGlue] recently posted a build video for “Making Rey’s Star Wars Blaster“, embedded after the break. The construction uses layered MDF sheets to build up the blaster, and it’s a treat to see it taking shape, ending with an amazing paint job. It’s a good way to learn about the techniques used to bring such props to life and help you hone your skills. But digging deeper led us down an awesome rabbit hole.
[CutTransformGlue] got plans for Rey’s Blaster from the Punished Props Academy – a prop and costume making team from Seattle committed to “transforming passionate fans into confident, skillful makers”. These folks have built a wide variety of projects ranging from guns, weapons, costumes, props and more, and are obviously extremely skilled at what they do. But they aren’t keeping those skills to themselves and in a series of posts and videos they are sharing with us such varied skills as Foamsmithing (gotta love that coinage), Molding, Casting, Painting, 3D printing, Vacuum Forming and electronics. If you’d like more information about supplies, check out the Tools and Materials section. And if all of this has given you the itch to build a Skyrim Wuuthrad or a Halo4 Sniper Rifle, head over to the amazing Free Blueprints section for a treasure chest full of downloads.
Like we said earlier, if building such stuff is your thing, it’s a rabbit hole from which you’ll find it extremely difficult to extract yourself. Have fun.

Nerf blasters have been around for decades now, exciting children and concerning parents alike. Most are powered by springs or compressed air, and are the ideal holiday toy for putting delicate family heirlooms at risk. Not content to settle for the usual foam-flinging sidearm, [Peter Sripol] decided to take things up a notch.
The build starts with a MEGA CYCLONESHOCK blaster, which uses the larger red NERF darts as ammunition. Water tanks are rigged to the outside, fitted with stainless steel electrodes. The original spring & plunger firing assembly is then removed, to make room for a firing chamber made out of copper pipe. A small taser-like device is used as an igniter. When the charging switch is pressed, current is passed through the electrodes in the water, which splits the water into hydrogen and oxygen gas. This is then passed to the firing chamber, where it can be ignited by the taser module, activated by the trigger.
Despite some issues with the blaster occasionally destroying darts due to what appears to be overpressure, it is capable of higher shot velocities than the stock blaster. For all its complexity, performance is somewhat hit and miss, but the cool factor of a handheld hydrogen bubbler is hard to ignore. [Peter] does note however that the combination of explosive gases and dangerous catalyst chemicals make this one build that’s probably best left to adults.
If this NERF hack isn’t dangerous enough, you might prefer these Taser darts instead. Video after the break.

This full-size replica blaster from Star Wars, most iconically used by Han Solo and Princess Leia, has everything. Flashing LEDs, blaster noises, LEGO, and yes, even an Arduino. Not bad for [Baron von Brunk]’s first project to use an Arduino!
The blaster was based on electronics and LEGO that were lying around and was intended for use for Star Wars Day 2014. (May the Fourth be with you.) “Lying around” in this sense might be a bit of an understatement for [Baron von Brunk], as the design of the blaster required the use of the LEGO Digital Designer and 400 blocks, some of which are quite rare.
The electronics for the project are tied to a moving trigger mechanism (also made from LEGO). The trigger mechanism hits a momentary pushbutton which tells the Arduino to activate the LEDs and a separate 555 timer and sound recording/playback device which handles the classic blaster sounds. The whole thing is powered by a 9V battery and housed in the front of the blaster, and all of the code (and the LEGO schematics) are available on the project’s site.
This is quite an impressive replica, and the craftsmanship that went into the build shows, especially in the LEGO parts. We think Han Solo would indeed be proud! If you’re ready to go even further with Star Wars and LEGO, you might want to check out this barrel organ that plays the Star Wars theme.
