Not properly fresh news, but another cute construction from leggor3.
"Pneumacube", a LEGO TECHNIC pneumatic cube, that folds/unfolds sequentially.
The pneumatics actuate in sequence for each face, while the air is provided by a regular compressor design, made of LEGO bricks and driven by a PF XL-Motor.
For more images from this creation, take a look at the respective webpage (in German).
Another nice, very well done and imagined construction!
