Airsoft minigun packs quite a punch

[Kuba_T1000] built a multi-barrell Airsoft minigun with an unbelievable firing rate and an almost inexhaustible ammo pack. The gun is made entirely from aluminum which meant some time on the CNC machine. The six barrels don’t rotate but they are all used, resulting in the carnage shown in the video after the break. That large box you see is the ammo pack, which can hold 16,000 BBs and uses an electric feed system to reach the necessary delivery speeds. It is certainly not something you’d want to run into as part of an automated turret.

Tank drone with automatic targeting and tracking

Humankind is making some great advances toward our own destruction with this tank drone. It’s got a powerful set of treads with an Airsoft rifle perched atop. Thanks to the cameras and the laser this thing can accurately target based on color. The hardware is controlled by a collection of Arduino boards connected via XBee so that Processing can be used on a computer. Just combine this with the facial recognition from yesterday and you’ve got the first generation of Terminators. Watch the clip after the break and you’ll realize that we’re doomed. [Read more...]

Mad machinist masterpieces

If a picture is worth 1000 words, by our count, [Ryan Commbes] has said 1.68×10^6 different things about his custom robot, airsoft, and monster truck builds. While we’re not ones to pick favorites, we agreed his Alpine TPG-1 (picture at the top) build is a step above the rest. Sadly, the forums with his build log doesn’t seem to be loading, but he says the basic process if you wanted to make your own is to gather pictures, measure, and create.

Autonomous tank terrorizing campus

tank

As a senior design project for ECE4007,  [Nate], [An], [Chris], and [Wink] built an autonomous toy tank. It is using a Panasonic IR motion sensor to find targets, then once it’s facing the target it switches to visual motion tracking through it’s web cam. If it can get close enough, it will stop and begin rotating the turret for more accuracy. Finally it fires a pellet. It’s brains are an ICOP technology eBox-2300 running windows CE. All of the programming is available on the site, as well as a breakdown of the various sensors and hardware. As you can see in the video after the break, it does a decent job. Given some more time, we’re sure they could speed up the target acquisition process. Maybe we should add a category for Georgia Tech final projects.

Portal-ish automated turret

turret

[RazorConcepts] has built this cool automated turret. It is a home made frame with an airsoft gun, a Roboduino development board, a rangefinder, camera, and some servos.  They programmed it to keep up constant random banter from the game as well as respond appropriately do different inputs. For example, it complains when you pick it up or knock it over as well as announcing if it has acquired a target. The range finder is mounted on its own servo which constantly sweeps back and forth, so the turret itself mainly sits still. You can see that the tracking is not so great in the video. [RazorConcepts] notes in the instructable that this is because the main focus was just to make it for “show”. We’ve seen our fair share of turrets before. We think he did a good job, but if it is just for show, maybe spend some more time on a nice body and smoother motion.

Airsoft hacking

[Barrett] sent in this hack he did to an airsoft pistol. He was using “tracer rounds” or glowing airsoft pellets and found that there was no commercially available way of charging them up with uv light before they are shot. He cracked open his pistol, removed the safety mechanism, and placed a UV led in it’s place. Now, when he turns it on, it charges up the pellets so they’re nice and bright. If he’s playing airsoft at night, won’t that bright purple light give away his position? yeah, we know he was probably just using that pistol to show the mod off.

Automated shooting range

targets

[Steve] was discussing airsoft with a friend when he came up with this idea. His friend was lamenting the lack of “action” style targets for their airsoft hobby. [Steve] took this as an opportunity to make his own automated target system. The targets themselves are made from Construx, a paper target and a piece of cloth to stop the airsoft pellets. Controlled by an Arduino and an ioBridge module, it has a web interface so he can switch programs from up range. You can see a video example of him shooting some targets after the break. Next,he should make it twitter where each target was hit.
