    Thanks! :D Oh whoops. I meant to link to my album, but by mistake linked to the photo. Here is the gallery with more details

    I got an inspiration last weekend, and decided to build a mini diorama of the Hoth rebel trenches on a 16x16 base. Once that was ready, I felt I had more in me. This was the result (the pictures are not that good, unfortunately)

    Thanks! :) Oh wow! Like magic! Thanks!

    I really like the new ninjago dragons, the one with brick-built heads, and try to collect them all. But there wasn't any cool dragon for Cole (the tiny one doesn't count ). So I decided to update the old set from 2011. Here is a link to the mod page, with instructions. Anyway LMK what you think, I built the thing in real bricks and then made the design in LDD. Do you also want to see pictures of the real thing? I don't have all the right colors, so it won't look quite as nice...

    You had my hopes up for a while there. I thinks it's a good decision. Maybe we can later make a multi-set contest Anyways, I'll need to re-think it. I really like the 10k limit, but I don't have any ideas on what to build yet... **puts on thinking cap**

    Back to the old drawing board, then.. I had planned on having the A model be 2 vehicles, and the B model a robot or a combo vehicle, but now hmm got to think something else.
  7. Sir Wolf
    Nice! I also stsrted on a motor grader, but in a different scale. I really like the look of it!

    I'm wondering if I can build a multipart set similar to 42023, with multiple things. If allowed, how should I calculate the volume, sum of the individual parts or just line them all up and then calculate the box they occupy? I thought it best to ask before I move onwards with my plans, rather than get a nasty disqualification at reveal time. I have already started, but not so far yet as to no be able to reverse direction, or even start over.

    Very interesting topic. I think I like it! I like the A-B theme plus the volume limit Just to be clear, are pull back motors classed as PF? It's not electronics, and not listed on the page, but was neither explicitly forbidden nor approved (like pneumatics).

    Great contest! Congrats to the winners! I was amazed by the number of votes and points I got, thank you all who voted for me! I entered for the love of cranes, didn't think I'd score any points, but yay! I had loads of fun making my crane. I actually modified it a bit, and now it's sitting there... One fun thing I noticed is that entries 1, 5, 13 and 14 ranked with their entry numbers! How's that for a coincidence!?

    Also, it can be an everyday device like Braigo, a Braille printer built with the ev3: https://en.wikipedia.org/wiki/Braigo

    As MajorAlvega says put ev3dev on it, and then start programming bots in your favourite language. I suggest you first choose one of the official models and try to replicate the sample programs that they show you how to code in the limited Lego programming language. That way you have clear goals, and something to aim for. I did this, and really learned a lot about programming it. I chose the track3r model and the missions that came with it. It was loads of fun. Now I'm looking at developing an autonomous sumo bot! Since you're a java developer, you might enjoy lejos more, but ev3dev is more flexible IMO, also someone started a java port for it: https://github.com/jabrena/ev3dev-lang-java As for programming a bot with a single motor function, you can go further. You can get non-lego sensors at http://mindsensors.com they have very interesting sensors that will allow you to explore more complex robotic topics like SLAM (Simultaneous Localization And Mapping). Maybe hook up a video cam on it and you have a mobile sentry robot ;)

    I just use the YouTube editor, it's pretty basic, but so are my editing skills. The only thing it didn't let me do, was create scrolling text (yes it will easily and happily rotate video). I do like how it comes with built in music search, which you can simply add to your video. All in all I was happy, it allowed me to do my editing on a simple laptop.
  15. Sir Wolf
    Ah, that explains why I can't see the cable :P I saw the video and I was impressed with the self-righting mechanism, very clever, well done! I also like your battery-powered hand-crank! Now that's clever! I think I'll build one for myself, to use with something. I just like the idea a lot.

    Wow! What an impressive crane! The video, it's really great, lot's of nice work you've put into it! I especially like the mud parts! Awesome! I bet it wasn't so much fun to clean the thing, but I was surprized by how clean the underside was. Good work!
  19. Sir Wolf
    I love this crane. It's simply stunning! How did you thread the hook cable? Does it go on the inside of the boom?
  20. Sir Wolf
    I think I'm done? The new and improved cabin, technic-style. I also enlarged the dashboard with more instruments. The operator now has more things to look at! :P I also created a trivial tilting system for the cabin. Here it is, the beast. In this picture you can see the full configures crane with all the modules engaged. I'll make one more white segment, but shorter, to extend the stumpy mast a bit (it's actually 2 modules connected without a middle part. The body of the crane is quite large to contain all the motors and counter-weights. A close-up picture of the crane main body, showing the boxy cover and the simplistic cabin. All in all, I'm quite happy with it. It turned out mostly as I wanted. The centre of gravity is pretty spot on the turntable and the counterweights allow the crane to extend the boom both forward and up. Functions * RC via SBrick with control to the 3 motors: 1.

    I love it. It's simple, and elegant! I think it looks better than the real thing!

    No ratchet, using motor resistance for these two. Seems to work so far. The M-Motor is linked to a pulley system that increases friction and reduces overall stress on the motor. The L-motor is directly connected to the load. So far it seems to be ok. I might need to implement some kind of a pulley system on the hook if the is not sufficient. But for now it seems to do the job. The XL motor that controls the whole boom assembly movement is connected via a worm gear and a 24-tooth gear, because it's quite heavy. The XL-Motor, and the gantry it's connected to. You can also see a bit of the counter-weights. I have now assembled the boom and mast and jib, and done some preliminary lifts. And then I realized that I wanted a different string as my cable so I ended up with a bit of a mess, but sorted it out eventually. I really like the new rope I use. It's the official lego rope, same as they use for the cables with round studs at the ends. Amazing stuff! Here you can see the whole crane from the tip of the jib See how thick that cable is!? And finally a sneak peek at the cockpit, very much WIP.
  23. Sir Wolf
    Really nice compact design!
  24. Sir Wolf
    Nice! Amazingly detailed! Will you make a single boom only or the full boom, mast jib configuration?
  25. Sir Wolf
    Thanks! I've now managed to make all booms nicely coloured, so that all extension modules are white, while all ends are red. I'll add pictures tomorrow. Thanks! I plan to build a cockpit for a minifig into it. It's been a challenge to build so small. Take for instance placement of the motors for the cable spools. Excuse the mess in the background. The L-Motor controls the spool for the hook, while the M-Motor controls the auxiliary cable that will raise and lower the jib (when there is no jib in play, it will be disconnected.
