    That's really beautiful! Reminds me of time lapse video of mushrooms growing (in a good way ).

    Wow, this is just astonishing! It's an achievement for anything of this scale to have significant functions, but to have full RC working as smoothly as this, as well as this degree of realism is simply amazing. As others have said, it would be a terrible shame to disassemble this beast without documenting it, so I really hope you make instructions!

    It's been done: http://www.eurobrick...showtopic=66099

    Wow, that's a really neat model! I would try to make the horse color contrast more with the background. Eg. horses white, center section black, no other white anywhere.

    I suggest studying akiyuky's astonishing GBC train module. All the movement is powered remotely by a motor on the train car. The key is that friction is very low, and everything is very well balanced, thus keeping the torque required to a minimum.

    Wow, the new loom looks awesome - eagerly awaiting the instructions. Very interesting and innovative use of the "timing wheel" concept. Perhaps this idea could be extended to make something like a Jacquard loom that can weave set patterns...

    Quite a few years ago there were white 1x16 technic bricks (in USA). I think I managed to get 30-40 in a cup - wish I'd got more now!

    This is a truly epic build - congratulations! I too am a big fan of non-vehicle technic MOCs and unusual mechanisms. (Nothing wrong with vehicles of course, but it is harder to be original.) I spend a lot of time on youtube looking for non-Lego inspiration - search for things like "kinetic sculpture", "mechanism", etc. One thing I would like to see is a very large scale walker that can actually walk efficiently...

    So - the laws of geometry live to fight another day... Incidentally, there are numerous examples of Pythagorean triangles in official models. E.g. a yellow 6-8-10 triangle features prominently on the side of the 42009: And 3-4-5's form a vital part of the 9398 chassis: I'm not aware of any 5-12-13 triangles in official sets, but I'd be happy to be proved wrong on that... Blakbird???

    Another kinetic sculpture for your enjoyment! Not much subtlety here - 50 Samsonite gears, 2 hailfire wheels, 60 #3 connectors, lots of 5x7 frames and 15L liftarms, 1 M-motor...

    Yup, your calculations look spot on to me! The yellow version was mine as well. That was much easier because it doesn't need internal support. The yellow gears are not too hard to get hold of, but finding 50 red ones was a challenge! With just 8 of either type you can make an octahedron...

    Enjoy...

    Here is my (WIP) entry. Not much subtlety here - one very simple function! Basically it is a pull-back motor and two "devastator" wheels, with three boat weights for balance. Plus I decided to blow about two-thirds of the parts on some rather unusual styling. Just under 200 parts at the moment - details of styling might change slightly. Video coming soon...

    Wow, that's nothing short of astonishing! Very very well done. Any chance you could make instructions?
  16. aeh5040
    Nope. "Hi" is a 2:1 ratio (geared up), "Lo" is 1:1, as Bzroom says. Just try it :) Differentials can be tricky ...
  17. aeh5040
    Well, of course it could be made more compact in various ways...

    Here you go:

    Wow, this is outstanding! A great example of what can be one by building smart and light rather than massive over-engineering (of course, that can be fun too!). Perhaps it would it be more manouverable and stable if the tracks were geared down more?
  20. aeh5040
    Awesome work! I'm guessing quite alot more speed would be possible indoors on a smooth floor (maybe a gym or convention center). Those bumps really don't help...

    I would definitely check out the brickshelf folders of Mark Bellis and Kevin Clague. There is also a list of old LUGNET posts that may be helpful. Since you only have 4 legs, you might need something like Kevin Clague's "one leg at a time" hexapod in order to keep balance:

    There is another pure lego solution to this one. First put a half-thickness liftarm onto the pin, then insert any minifig-tool type piece into the pin through the liftarm, and pull them off both together. I know it sounds unlikely but it works every time. (The tool enlarges the pin slightly making the liftarm grip it very tightly).
  23. aeh5040
    Nice! Very original idea. The mechanism looks very different from what I was expecting...

    And a couple more

    Thanks for the link! The mechanics are pretty straightforward - the hardest part was fitting motor, battery box and gearing inside,and then getting the center of mass exactly in the center (otherwise there would be a lot of wobble). I am indeed working on a rolling version! Here are some other variations on the theme using other gears:
