    Can't you start with the narrowest available and widen it until you get to 13? There was a post/thread a while back on here on the narrowest axle steered with a differential (driven). Though, if my memory serves me right, has to be above 13L, unless you do without a differential.

    Might need hydrofoils and a very smooth water surface But, wait: sailboat requires sail/wind and that very same wind creates too much water surface agitation. This in turn requires a bigger boat. All in all, not sure if at all feasible

    Congrats to All. I was busy and have forgotten to vote but, that would not have affected the results as most my votes would have gone to #1 anyway. I thought I had seen enough MOCs of cars and got bored of them. Now, the winner has proved me (and many on here) very wrong.

    Thank you. Those sound very promising.

    Just found this on youtube. Apparently a lego fan built the contraption and made a small video of it. And, he even referenced this thread, cool! http://computerbackup.vidlify.net/en/video/pGgv7VNb6Nk/Lego-Technic-Free-Wheel

    It seems there was a GBC Challenge on TLG's Mindstorms site earlier this year. Checkout some of the entries on the page below. http://www.us.lego.com/en-us/mindstorms/community/browse/?query=GBC&order=date&category=

    It's a bit pricey. Though, it is more tempting to try the EV3 sensor/remote ... Any more input ideas on this topic? for sure many others have faced the same challenge/frustration.

    Thank you. I read a bit more about those on the apple store and apparently they require a server app to run on a computer. This means that both the NXT and the remote need to be within the computer's range. I'll check MIT, as an alumni, I'm a bit biased towards whatever comes out of there.

    It seems I'll be going the i-phone/i-pad route. There are many apps on the apple store and all of them 'promise' the moon. Anyone has experience as to how solid/reliable they are?

    Thank you... this has been a 'slow' morning

    This is going to be an expensive summer.

    I've seen this somewhere else (it's not yours ). Do you know who the original author is?
  13. DrJB
    Thanks, those are certainly good alternatives. I'm taking here the 'lazy' way as it's a school project for my son and want something more-or-less 'fool-proof' that won't die during a demo (as in BT). I guess the 'simplest' would be to use the EV3 sensor/remote with the NXT, but I'm not sure they're compatible.
  14. DrJB
    When it comes to the EV3 and RCX bricks, the answer is easy as there are remotes for each platform (shown below). However, I do not know of nor could I find a dedicated remote for the NXT. Has anyone come-up with a work-around?
  15. DrJB
    Yup, and for someone to have the dedication/drive/time to accomplish such mega project is equally mind-boggling.

    These tend to be more common in Europe, and I found this while perusing a MindStorms blog. Rather neat, check it out. and some blog in German http://www.freggelwe...s_Parkhaus.html

    Nice and Compact. Reminds me of the Pontiac Aztek.

    Almost, the set with the absolute largest number of black panels (28) is the FLL 2012 Senior Solutions
  19. DrJB
    Which set was that?
  20. DrJB
    if you're buying an old set anyway, why bother buying new parts for it? From my experience, used/assembled sets, once washed, typically have good quality parts ... but of course, it's your $$$ ;)

    I've seen enough snow in my life to tell that some of it is suitable for sliding toys, other might not be. How well the vehicle handles/grabs the snow depends a lot on the size of snow flakes. This is especially true with the small lego liftarms. One rule that seems to work: The bigger the contact surface, the better the vehicle can 'float' on the snow. Back on topic: Very nice contraption that you have and will definitely following this thread.

    In the top of the LDD screen, you can type the angle you wan DIRECTLY.

    Looks like a Black Lamborghini Aventador ... the one in London, that got wrecked by a WV.

    Try to get the 8996 Bionicle Skopio set, it's full of technic parts, and often you can get it for decent price. Other Bionicle Battle Vehicles and Exo-Force sets as well pack a good amount of Technic parts.

    Very 'inspiring' questions you're asking here. Is it fair to 'infer' you've already answered most of them? When 8455 came out, it reminded of 'cascaded' functions I learned during a 'Pneumatics Automation' course I learned in High School few decades ago. I got 2 copies of the 8455 (20 cylinders!) and few more valves off bricklink. I wanted to replicate many of the L/U/T cycles I had learned back then. The closest contraption I built was , which uses an 'L-cycle'.Yes, pneumatics offer a lot of potential for automation ... if only one has the time (and parts).
