Which is the real one??
I found this some days ago in Brixe63's photostream at Flickr and until I saw the following image I don't realized that all parts where built in lego pieces!! ALL PARTS!

LEGO GBC 10 modules by laurens gauwloos
In their site laurens gauwloos pubkished this 10 modules GBC with some interesting features, and reinterpretations of known gbc concepts and techniques.
"This Lego great ball contraption "GBC" has 10 different modules and are sturing with 8 PF-M motors and 2 PF-L motors. It took me 1 month to finish it. It is 2 metre long and 30-40 centimetre width. It contains: A ball shooter, a moving bridge, 2 ball lifts, a ball accelerator, a ball wheel,.... It is powerd by 2 PF-battery boxes and 2 switches to have the righe direction. there are also many delays with gears and worm gears.
You'll see that I have used tracks for the lifts and for the ball wheel and a big shock absorber for shooting the balls."

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
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.
