Introduction: Lego Portal 2 Sentry Turret and Wheatley
Hey guys, and welcome to another instructable! If you missed my last one, go ahead and take a look at my page, it should be the first one! If anything is confusing or unclear, don’t heasitate to ask, and I will try and get back to you in a day or two. Enjoy!
Step 1: Wheatley
Here are the pieces you will need for Wheatley
Step 2: The «Head»
For Wheatley’s face, take a translucent light blue stud and put it on the inside of a mini white satellite. Connect that to the bottom of a black sextant brick.
Step 3: The Handles
To make Wheatley’s handle things, take two black handle bars and two black 1×1 clips. Put them together like so. Connect them to the sextant and bend them forward as desired.
Step 4: The Back
The back of Wheatley just takes a mini white satellite piece placed on the opposite side of the face.
Step 5: The Final Step to Wheatley
To finish it off, take two white satellite dishes and place a white stud on the inside of each of them. Take the two pieces and place them on the empty sides sextant. There you have Wheatley!
Step 6: The Sentry Turret
Here are the pieces you will need for the sentry turret.
Step 7: The Body
To start off the turret, take a white jumper plate and two black 1×1’s with studs and place them like so.
Step 8: The «Wings»
To make the sentry turret’s wings, take two white jumpers and four black studs. Place two black studs on either side of the 1×1 with stud and put the jumper on top of that. If you want to open the wings, take the other two black studs and stack them on the original studs.
Step 9: The Front Two Legs
For the front two legs, take two white antenna and place them on the remaining 1×1 with stud.
Step 10: The Back Leg
This one’s a bit trickier. Don’t worry if it hangs really low, the pressure will push the leg up once it’s standing. To make the back leg, take a neckbracket and put it on the back of the 1×1 with stud. Then, take a half axel and place it upright into the hole in the neck bracket (if this gets confusing, don’t be afraid to ask me in the comments for help). Take the antenna and place it upside down on the half axel (sorry, this sounds really bad…). The white sloped brick is optional, but helps give a nicer look to the back.
Step 11: The Final Step for the Sentry Turret
Finally, you did it! Okay, so you can use either a translucent red stud, or a translucent red «smooth» stud. Personally, I think the smooth one looks better, but I know it’s a rare piece, so the red stud looks just as good. Thanks so much for taking time out of your day to look at my instructable, it really does mean a lot to me to know that people out there are actually interested in what I build. I hope to continue making more builds, and maybe inspire you to try some creative building of your own! Thanks again! ~Shade Heart
Introduction: Lego Portal Turret
These are the instructions for my popular design of a laser turret from Portal. It’s all Lego; you won’t need any other materials to make this nice display piece.
Step 1: Parts Needed
Here are the parts you’ll need. You may have some, most, or all of these in your own collection; if not, you can get them from Bricklink.com (or Lego’s Pick-A-Brick , but they tend to be much more expensive, if somewhat easier). Part names may be different between Bricklink and Pick-A-Brick.

An Excel sheet of the parts with links and more information is attached.
Step 2: Step 1
Onto the build! I’ll add hints down here for the Lego-illiterate. 
Step 3: Step 2
Yes, the tiles are supposed to swing back and forth loosely here. They will be secured later.
Step 4: Step 3
Unlike the previous step’s bricks, these have studs (the knobby things) on all four vertical sides — they are often called «travis bricks». This step ties the whole assembly thus far into one piece.
Step 5: Step 4
Step 6: Step 5
Step 7: Step 6
None of the non-white pieces’ colors here matter much; they won’t be very visible.
Step 8: Step 7
Notice that you do the same thing on the other side.
Step 9: Step 8
Step 10: Step 9
Step 11: Step 10
Step 12: Step 11
This connection may be a little loose; using newer clips or gently squeezing the clips before attaching the brackets can help.
Step 13: Step 12
The 1×1 slopes are called «cheese slopes», one of my favorite parts.
Step 14: Step 13
Step 15: Step 14
This one can be a bit tricky; the bases of the sticks, when put in together, should stick tight in the red plate.
Step 16: Step 15
Fit the previous assembly in the 1/2-plate gap that goes around the body. Try to fit the balls of the lever handles in the gap in the middle; this may take several tries. Once they’re in, gently squeeze the body to slightly shrink the gap, to hold the eye in place.
Step 17: Step 16
Did you get the eye in? Great!
Step 18: Step 17
Step 19: Step 18
The tap’s top can move around a bit within the slope, making for some nice angles.
Step 20: Step 19
Depending on the parts you have, you may have to pull the hands out of your minifigs’ arms. It’s okay, they won’t mind.
Step 21: Step 20
Step 22: You’re Done!
Once you’ve adjusted the legs to your liking, congratulations! You now have your very own Portal turret. I recommend using it only as a display trinket; it won’t hold up to much play.
Step 23: Credits
These instructions were built in LDraw/MLCad, then screencapped in LDView and edited in Photoshop Elements.
Step 24: …But What About the Laser?
Oh, right. You’re wondering how I achieved the laser in my photograph? Don’t worry, your turret won’t actually kill you.
Materials needed for laser effect:
Laser light (warning: don’t shine in anyone’s eyes, etc.)
Misting humidifier or something else that creates a mist or fog
Step 1: Shine laser into turret’s eye (it’s okay, he can’t be blinded)
Step 2: Fog up the area with the humidifier to make the laser visible
Step 3: Take picture
Here’s my setup:
Remember when Lego used to be cool before you got all these sets with custom shaped pieces and step by step instructions on how to put it together? Seriously, Lego used to be about nothing more than 4-5 different shaped bricks that you used to foster your own imagination. Now? Well, some would argue that Lego is more awesome than ever whereas some are pining for the old days. We’re not here to judge. But I will say this. When I saw this Portal 2 made out of Lego I was definitely on the more awesome now bandwagon.
So what happened after that? Only coming across instructions on how to build your own lego turret. Yeah, legos rule.
Step 1: Parts needed
Here are the parts you’ll need. You may have some, most, or all of these in your own collection; if not, you can get them from Bricklink.com (or Lego’s Pick-A-Brick , but they tend to be much more expensive, if somewhat easier). Part names may be different between Bricklink and Pick-A-Brick.
