  1. Hello dear EB members, it really has been too long since I posted anything from my hands, but that only means I am lazy posting - not building. There are several creations I would like to publish ASAP, so here is the first one: The Dark Side of the Force never rests, so must not Lord Vader himself. Although he is strong with the Force, he is pretty tired after full 6 days of pedalling on two of our LUG's events in October and start of December. I give you The Dark Side Of Exercise. I got the idea a long time ago and got extra inspired by Jason Alleman a.k.a. JK Brickworks and his moving masterpieces - especially the Sizifus. After thinking about it for too long, I finally bought the 75111 Darth Vader set, which had to be modified quite a lot on the inside - outside remains the same. All the skeleton with bionicle ball joint parts was replaced by technic axles and u-joints in order to get a freely movable body. A free rotation of hips, shoulders and waist was also necessary. Free movement of ankles anf wrists is provided with bar pieces (I admit I cut 4L bars into 2L bars - I never thought I was capable of such horid acts ) Pedalling torture device was a bit more of a challenge. The main problem was getting all the necessary motion from rather spacious pedestal to a slim orbitrek body. I am pretty happy with the outcome, even though the gearing in the pedestal is a mess. The main goal was to get the body in its highest position twice in one revolution of the pedals. The gear ratio between those two is therefore 2:1 and they have to be synchronised so that the body is at its highest when the pedals are horizontal. The rest of the body motion is provided by linkages amongst freely movable parts of the body and the orbitrek. Another part run by the same motor is the big wheel, which is propelled by a small wheel inside the orbitrek body. This wheel is geared up a lot, so it turns fast enough. Running this MX bike wheel by contact proved to be most demanding for the whole system and caused most friction and wear of the parts and motor. A LEGO chain is not the best way to drive anything for a long time as well. You must guess it was a lot of fun to repair after it broke a couple of times during the exhibition. To conclude this presentation I give you another photo in Ludicrous Speed mode and of course a short video of swinging this man's booty from side to side Thank you for your attention and "May the Force be wih you!!!" Best regards and a Happy New Year, Miha You can check out bigger photos here: http://bricksafe.com/pages/MajklSpajkl/the-dark-side-of-exercise
