DIY 1MW Pulse Laser Gun

This custom pulse laser gun is packed with a 1 Megawatt laser capable of destroying a multitude of materials.  The 1 MW laser is able to be battery powered becuase it only pulses on for a fraction of a section to burn through plastic (and even wood) instantly.javascript:;
 The handmade pulse laser gun took 70 hours to build and has a brass and aluminum finish with a bit of plexiglass.  At just 32 cm long, it’s compact and light enough to carry.  The batteries can fire 50 shots on a single charge of its Li-ion batteries. While there aren’t any build details available, you can check out our other DIY laser projects for inspiration.

Paintball Pistol Turned Sniper Rifle

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.

SMAC Mag: Spider’s Minimal Analog Control Paintball Gun

[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.
