Hack a Day
[Chris Suprock] is interested in using technology to improve your accuracy with a firearm. To that end, he’s using an Accelerometer mounted to a gun to gather feedback about each shot. The hardware setup is pretty simple. We don’t have specific details, but it looks like he’s using a QFN accelerometer chip like you would [...]

After reading The Five Fists of Science, a retelling of ‘war of the currents’ between [Tesla] and [Edison], [Rob] knew he needed a Tesla gun, the sidearm of the story’s protagonist. Since nothing as stupidly awesome and dangerous as a portable Tesla coil has ever been made, [Rob] needed to make his own. [Rob] started his build [...]

[Unusualtravis] came up with this fairly slick electronic catapult. This easy to construct and moderately cheap rig has an arduino as the brains and controls for 3 servos. One is the release, another controls tension, and the third controls the angle. Both the circuit and the construction are very simple making this a perfect weekend [...]

This open source sentry gun controller board builds on a great concept by getting rid of the Arduino board. The previous version was an Arduino shield, but this upgrade keeps all of the cool features by rolling the necessary parts into one smaller footprint. The image above doesn’t quite convey the scope of the project. [...]

In Norse mythology, Mjöllnir is the hammer of Thor, forged in a contest to create the most wondrous and munificent tool for the gods of Asgard. While we’re not aware if [MrCrowley] recently made a bet with Loki, his version of Mjöllnir, a gigantic spud gun powered by MAPP gas, is wondrous enough for our tastes. Unlike most of the [...]

Here’s an image of a bullet’s path to the target. There’s a couple of things to note. First of all, this is not a tracer round, the projectile actually has an LED incorporated which was picked up as a trail in the long (relative to bullet speed) exposure. The second – and most obvious – [...]

A few years ago when [Dr. West] was wrapping up his collegiate studies, he put together a pretty cool coilgun for his senior project. The gun was built to simulate the Scorched Earth computer game in real life, but due to time constraints he was only able to build one turret instead of two. The [...]

Boeng and the US military found some systems on new P-8 Posiedons to be defective. The culprit: counterfeit electronics. These are scrap parts from 80s-90s electronics that have been re-branded and sold to the government as new. Many of the parts have been linked to dealers in China, but the Chinese government feels no need [...]

Every reasonable person prepares for the future. Whether it’s matching your employer’s 401k contributions, making sure you have bread and milk before a snow storm, or saving for your kid’s college fund, planning for the future gives you a comfortable life. [Gord] has exceptional foresight; he build an awesome Louisville Decapitron for the upcoming zombie [...]

Good old [Jörg Sprave]. That guy just doesn’t quit building insane slingshots. If he’s not honing his machete slinging skills in preparation for the zombie apocalypse, he’s blowing out car windows with giant steel balls. The huge cannon you see above is modeled off a small slingshot he made a while back, which fired 8mm [...]

[Mark] and his friends love fireworks, but got tired of the traditional ground-launched mortar rounds, so they decided to spice things up a bit. A while back he purchased an Army-issue bazooka at a gun show but didn’t use it for much, so it sat unused for about 10 years. He dug it out of [...]

They say all’s fair in love and war – trust us, you don’t have to tell these guys twice. With the war in Libya raging on, the rebels have turned to anything and everything to help give them the upper hand. Engineers and engineering students have put aside their work and studies to become the [...]

Although this isn’t the first pneumatic air cannon to be featured on HAD, this “paintball shotgun” is certainly one of the coolest. While most air cannons have little practical use besides looking awesome and being cool to play with, this cannon, according to it’s maker, has actually been used successfully in actual paintball competition. The [...]

[Jeremy] wrote in to show off his latest creation. he has built a two barrel pneumatic air cannon. Eschewing the traditional approach of having a single barrel and pressure chamber for his spud gun, [Jeremy] wanted to have a double barreled version. Since he was doing this pneumatically, he had to rig up a way [...]

Hack a Day
This collection of gauss weapons use rare earth magnets to accelerate projectiles to damaging speeds. They work using the same concepts as a coil gun, but instead of just one projectile travelling along a length of guide track, there are many projectiles that work in a chain reaction. A series of magnets are placed at [...]

Sometimes, you just need more ammo available. In this weapon mod, the chamber of a 12 gauge shotgun, a hammer from an 1857 Remington Perc Revolver, and other parts from an Italian auto shotgun were all combined to make this happen. The gun is of questionable legality depending on what state or country it resides [...]

This slick little chronograph can tell you how fast your paintballs are going, as well as what your firing rate is. In this instructible by [Klash69], you can see how to build one for yourself for less than $40. Chronographs themselves aren’t usually too interesting, but we thing he has done a great job here. [...]
