Chris Myles a robot engineer and Portal 2 fan has created functional replica mini Portal 2 personality cores, using SolidWorks and a number of other components including Eden 350, lancing device springs, paper clips and LEDs to name a few.
Chris has created Wheatley, Adventure Sphere (Rick), Space Sphere, and “Fact” Sphere, watch the video after the jump to see how the replicas function and the detail that has gone into creating them.
Unfortunately Chris is not selling or making any more of his mini replica Portal 2 personality cores.
**Note: The paint around the Space Sphere eye is yellow with a touch of orange (Technically Lemon Yellow with a touch of Saffron Yellow) and the LED is light orange ( a touch more yellow than the Omni-tool I made). I guess it just looks more red when I film/photo it.
