Using these images as canvases, I started sketching the outlines of the 3 views. The design started from sketches found online. This sensor is nearly invisible from the front once assembled. The lidar sensor (time-of-flight) is on a chip with a rectangular profile.

18 individual expressions and sounds used in this go-round. It is inline with the black infill strip, making it essentially invisible once installed. The sounds are stored on a microSD card, which is accessible from the back side so that sounds may be updated or changed later. With some basic sketches found online, I started modelling and planning. I took some liberties in the design, trying to make it appreciably the same as the one seen in the game, but functional and printable. Use Portal turret sounds and voices from the game. Close up and go to sleep until someone else comes along. If the person is no longer there, run a little scanning search routine. If the person is still there after opening, fire until they drop. Use a crank mechanism with sliders, just because. Open the "wings" if it senses someone in front. The goal here was to make it move in 3 "axes", with spoken sound from the game and LED's to simulate firing. This design uses an Arduino Nano, an MP3 player chip, distance sensor, servos, LEDs and 3D printed parts. For me, this was an exercise of properly modelling the entire assembly in Fusion 360 first, before building anything. This Christmas, I decided to design and build a working Portal turret gun from the game A way to control you Turret gun! Control multiple turrets with a single controller. CARA MIA! - Master Turret Control is here!! -Ĭheck out the Master Turret Control.
