Still on the pneumatics mood, I've decided to bring this week, another fully automated pneumatic model.
It is a fantastic module for any GBC display. An automatic closed loop pneumatic excavator, built by Jetro (linmix), a veteran Hispalug member.
It is something I had the chance to see working live, during last December, at the 2nd Hispabrick in Barcelona, and which really amazed me!
Jetro has also some extra photos from his model, at this Brickshelf folder.
