More mechanical sculptures

We already seen mechanical sculptures like this from aklego, this time we present the sculptures from aeh5040 the creator of the previously featured seven segment dysplay 

Parda's LEGO TECHNIC pneumatic compressor V4

This is my 4th Lego Technic compressor, after little modifications it has been used in a pneumatic sequential GBC module that I will present soon. Very simple yet effective.



My previous compressors:

Automatic gearboxes

There are a few kinds of Lego Technic automatic gearboxes, here some examples:

The first one, a two speed gearbox by Sariel, based on a 3 speed design by Misha van Beek 

Another automatic design by Misha van Beek 

Click Here to see it working

This gearbox by Zblj using 2 differentials switches between 1:1 and 1:5 gear ratios:

Sariel make a more compact version of this and published this two shots at facebook

From the same builder is this 3-speed "simple, yet effective gearbox, using a very unique design to change gears"





YotamPoleg show us in the first part of this video a real CVT gearbox:

Another interesting concept, this one is controlled by a centrifugal device:


By error4385

And finally my own first prototype of automatic gearbox, mixing Misha and Zblj concepts, two differentials to switch between 1:1 and 1:5 gear ratios, and a third differential to unlock the 1:5 gears when more torque is need and lock it when less torque and more speed is wanted, also the 1:1 gears got anti-return device in order to prevent the stop of the entire gearbox.
