[Ryan Palser] wrote in to tell us about his Portal Turret. [Ryan] set about making this Portal 1 style turret by first carving a Styrofoam form, bondo and waxing then casting molds of the various components. Anyone interested in mold making (like us) should check out all the pictures and comments in the stream. The turret’s camera lens style eye has some excellent detail including a laser cut aperture with text inlay. A couple LEDs behind the eye assembly provide the signature red glow and evidently [Ryan] also fitted the little guy with a red laser. An internal Arduino (Incident Resolution Chip?) takes ques from a PIR sensor mounted in one of the turret’s arms to play one of 17 sound clips through a sparkfun MP3 player shield. In order to fight repetition the sound module runs through a playlist of the 17 tracks then shuffles it before playing through again. Theme music can also be spammed by pressing a button in the back of the motion sensing arm. The turret can be battery powered or plugged into a wall socket for constant operation. All that’s missing are the Aperture-Brand Resolution Pellets. We would love to see this integrated with some similar turret projects previously featured here.
Are you still there? We have more Aperture Science stuff including a Sentry Turret, Weighted Companion Cube, and even a portal shirt. If you are interested in more model making check out the spectacular Daft Punk helmet build from a little while back.
As many of you are probably aware, Portal 2 was released last week, and gamers have been going crazy over it. Over the years, people have constructed replicas of their favorite in-game items and “characters”, including portal guns, companion cubes, and turrets.
After playing Portal 2 for a bit, [Jonathan] wanted a turret of his own quite badly. Rather than construct it from hard plastics and resins however, he decided he wanted to construct a cuddly turret that talked.
With the assistance of his friend [Leigh Nunan], he is now the proud owner of a plushie turret. It’s a bit smaller than you might expect, but it is packed full of turret personality. The plushie plays audio from the game, can sense motion near its face, detect if it has been tipped over, and also knows when it has been picked up. [Jonathan] added all of these features by stuffing an Arduino inside the turret, along with a wave shield for playing sounds. Proximity and motion sensing are provided via a trio of different sensors, enabling the turret to behave in the same way its in-game brethren do (minus the machine guns).
It really is a neat little toy, one we would no doubt be glad to have around. Keep reading to see a short video of his plushie turret in action.

Couch potatoes have a new line of defense thanks to this remote-controlled turret. The gun itself is a hacked down airsoft model. The mount started with a servo motor in the center of a plastic cake box. A thin strip of plywood was added, along with a couple of sliding furniture feet to stabilize the platform as it rotates. A second servo mounts to that platform, which allows the trajectory of the projectile to be adjusted up or down. A PIC 18F4520 controls both of the motors, as well as the firing of the airsoft module, all while listening for commands from an IR receiver. Just adjust the firmware to match an unused device on your universal remote and the power to annoy your roommates will be at the tips of your fingers.
You can see an overview of the build process, as well as a demonstration of the final project in the video after the break. The page linked at the top has a very detailed build log but some of the ‘next’ buttons on that page don’t work for us. Luckily you’ll see a table of contents in the right column which lets you navigate around these bad links.

Project Thunderbird is an automated predator and pest control system. It consists of a pellet gun mounted in a motorized base. The icing on the cake is a 60x zoom camera that has cross-hairs superimposed on the picture. This reminds us of the Internet hunting for the handicap we heard about years ago.
In the video after the break you can see how the motorized base works, watch the trigger-pull motor, and observe a demonstration of some target practice. The creator, [Gadgetapodimus], mentions the possible sale of plans and kits as soon as he completes the system. Perhaps it would be better if this was not easy for people to build.

Pay close attention. At roughly 36 seconds we see Asimov’s laws going out the window. We’re pretty sure we saw this little autonomous battle bot take a shot at a human. We can’t tell for sure, but it looked like it enjoyed it too.
This bot is being built by [xdream] to compete in the Mech Warfare section of the Robo Games 2010. His target acquisition system and firing are completely autonomous. We think his motion is controlled by an operator though.
This little fellow may seem harmless enough, until you realize that those servos and guns could be replaced and this “little guy” becomes that “big fella”. That’s not anything the maker suggested, we’re just pointing out that a killer robot is only cute when it’s small.
[Jared Bouck] is on a roll this week. We just covered his Diamond thermal paste and now he’s got more for us. To celebrate the re design of his website, he has released the plans for the paintball turret. As you may recall, we absolutely loved this design when he originally showed it to us. Though he has had kits available for a while, he has finally put the plans up for download. You can cut your own parts and build it yourself. He mentions that version 2 is coming shortly, we wait with bated breath.
[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.
