    This really is lego at its best. Thank you Barman and others, for a fascinating 'learning' experience.

    There are way too many DBG parts in Akiyuki's GBCs, and it's getting 'pricey' to get DBG parts off bricklink ... unless one wants to build a 'circus' (colorful) version

    Your LEGO regrets

    DrJB replied to Tariq j's topic in Community

    Sorry ... what's a lego challenger?

    Thank you for sharing. I like how you implemented the tit of the front wheels (that's quite realistic) as well as the tilt and up down of the blade. Too bad THLG does not make a larger turntable. Now, typically there is no suspension and I'm not sure about the springs you have on the front axle. Also, it looks like the tandem wheels of the rear are driven by gears/chains, and this is quite realistic as well. The only aspect I am not sure about is the pivot point between front and rear chassis. I know on CAT/Deere, the pivot point is BEHIND the cab, whereas for Case and New Holland, the pivot is in FRONT of the cab. Each design has pros/cons (of course). Though, I am not sure if the Volvo is like you depicted. Great Job!

    That is real nice MOC, do you have an LDD file u could share? Or better yet, can u describe the various functions? Now, one thing I noticed, it as about the articulation point. Some OEM put such point in front of the cab, others behind. When the articulation is behind the cab, the cab's weight gives the machine better traction in AWD or FWD. Which have you implemented?

    That's a piece of history that you got, enjoy! I always wanted to have one of those, even back when it came up, settled for the red tractor and yellow forklift.

    Can't wait as well. I'll try doing an LDD as soon as instructions are available ... as long as there are no 'illegal' connections (we all know how finicky LDD can be)

    Thanks, I somehow thought it was the same axle going through. It must have been 'difficult' to figure this out from just the video. If anything at all, this gives an appreciation into how much work it is to reverse engineer. Thanks again.

    I'll give my 'twist' on Technic vs. else. I'm guessing many of us (if not ALL of us) who are interested in technic have some sort of engineering background (I'm a mechanical engineer). Yes, I do find technic a way to replicate working-mechanisms out there but lately, I've been drawn to the more 'artsy' side of Lego, be it fancy/modern architectural pieces or or even rock/mountain shaping. Those really require some 'art' aptitude that is certainly not availabe to everyone. There must be a reason there are way more engineers than artists ...

    Of all machines I've worked on, graders tend to be the most intricate in terms of driveline and hydraulics. For sure, a grader a-la 8455 would be the perfect flagship. One can only wish/dream, yet with all the pneumatic components available today, a grader is not too far fetched an idea. Edit: looks like we posted within seconds ... did not see your comment.

    I've made the same observation a while back. My belief is that is plain marketing to 'up' the parts count. Many of the new sets (be it technic or else) contain way too many tiny pieces (that are easily lost), and those are not 'friendly' for grown-up men.

    From what I've seen, most cylinders tend to be either yellow/orange or dark gray. Not saying black do not exist, but I have not seen any.
  13. DrJB
    Very nice. Gotta love those technic frames, as they do come in handy. Now, a while back I saw a professional Stable-Camera-Support, and I wonder if such device can be replicated with lego.
  14. DrJB
    Agree with all above about the nicely done MOC (I still have the SUV assembled and displayed). Now, I know many on here like the realism of fake engines, but in a distant future, when all automakers would have switched to electrical power, these parts would look prehistoric ...

    Absolutely gorgeous. Is that a fresh or salt water tank? Can't really tell from the picture. The light intensity and colors say saltwater but the plants say fresh water. Which one is it? Also, that looks like a 210G tank, correct?
  16. DrJB
    LOL ... I must have missed the video, I only saw pictures. Found it, it was a youtube link

    I'm not sure what optimization really means (in this context). When designs (cars and consumer electronics) are optimized, typically it is to take cost out of the product. Sometimes optimization refers to balancing various performances (ride vs. handling in cars). Optimization tends to go after costly parts. When it comes to software optimization, it usually revolves around speed and using less memory. Here, with the EV3, I am not sure what optimization will do, are we after faster running programs, smaller number of sensors, or else?

    Might be difficult to replicate the 'sound' aspects with Lego. There is one reason musical instruments use either metal or air. Metal tends to have high frequencies and low damping, plastic does not. So, yes even if we can replicate the mechanisms with Lego, I bet the sound will NOT be that good.

    Well, somehow I can't make it with two 5L axles. The first axle has to go through 5L (parts in between, and stick out 1L on each side. One side connects to the 2x 2L thin liftarm with cross holes, and the other end connects to a 2L axle joiner. As such it must be at least 7L long. But, since it's sticking out 2L (when connected to the 2L joiner), it has to have a 8L length. Now, a related 'issue' is on page 29 (step 9). There, it calls for 3x 3L axles, but in the picture I can only see where two are placed (the cranks that connect the 4x 2L thin liftarms).
  20. DrJB
    Thanks for checking. Then I'd need to look at the LDraw file (in a 3D viewer) (no LD file available) The view angle from the instructions does not tell how to attach those axles.

    Thank you BlakBird ... I just felt like throwing some math in, as that acronym reminded of a course I took a long time back. :) Now, for the fun of it, I'm building the Invisible Lift in LDD. I think there is an error in step 17 (page 34). The inset calls for 2x grey axle of length 5L. I think what is needed there are 1x 5L and 1x 6L. Anyone encountered this?

    Since we're on this topic, might as well. Here are few pictures of something we did a couple of years back, to raise awareness about breast cancer. There is even a die-cast version for collectors. Precisely ... it's a win-win, for both the cause and the sponsor. I'm not sure Japanese men and Italian women make a good match ... ... or maybe I need to expand my 'geography'.
  23. DrJB
    The answer was given above (post # ). I think it's to make the frame kid-prrof, and prevent kids from playing with small/tiny parts (and risk swallowing them).

    What does LDU stand for? Not sure what I was thinking but, to me LDU is a matrix factorization algorithm/form. It basically states that any square/symmetric matrix can be factored as an LDU, for (Lower Triangular, Diagonal, Upper Triangular). Of course, then there is the LDL', L' = L transpose.

    Could not agree more, but I 'floated' the idea few months back of having technic parts in women colors (pink/magenta/purple...). Not sexist at all ... Someone told me once the fundamental difference between men and women is: Men say 'as long as it works', women say: 'Make sure it's beautiful'. So, if TLG is willing to add (girl) looks/colors to function, maybe we'll see more adoption of Technic with our significant others. For now, I'm not sure TLG is willing to venture that far, except for few 'small' technic sets, and of course Elves and friends.. For sure it does!
