A Lego truck turns into a sports car. Inspired by the '80s movie "Condorman"
Lovely transforming tuck in brick style, combined with Power Functions ;-) by 3okapis (youtube channel)

Lego Oldham coupling and Schmidt coupling
"The Oldham coupling and Schmidt coupling are two various mechanical solutions for transmitting drive between two parallel axles that are not aligned in line".
As wroted on Sariel's Webpage: ( Visit for full explanation, instructions, more information and Moc's)
That makes this two mechanisms an alternative to universal joints, which are long, and to gear wheels, which only fit in specific spacings and affect power/speed ratio if not meshed at 1:1 ratio.
The Oldham coupling consists of two identical rotors, each connected to one axle, and a sliding element between them. In short, the Oldham coupling is short and maintains 1:1 ration, but is complex, fragile and has large diameter.
The Schmidt coupling consists of three discs or triangles connected with links, it can work while its input and output are moving relatively to each other. That makes it an interesting solution for transferring drive to the moving elements of your construction. The Schmidt coupling is also extremely robust and can handle high torque while generating minimum backlash.
A "real" Schmidt coupling, as you can see the Lego Technic version works perfectly...

Akiyuky's screw And my own version..
While preparing the GBC for the 5th Hispalug Meeting i've decided to build a replica of this extremely interesting and complex model from Akiyuky, in the design procces the need of specific pieces make me realize the level of building precision that this module requires.
Here is the original and my "different" version:

Lego Technic Container Crane
Excellent creation by Barman, controlled with Power functions.
As wroted in the video description:
"Minifig scale Technic container crane, that can load and unload containers on the 10219 Maersk train, the trucks or in the depot.
Using Power Functions to controle the train and crane.
Train is powered by 2 PF train motors
Crane moves by 3 M-motors and a old 9V micro motor (red)."

Sheepo's Garage: MINI Cooper Mark I
The last car presented at Sheepo's Garage is a MINI Cooper Mark I, featuring several mechanisms that appear in the real car, as this builder has accustomed us.
