    Among the free and commonly available video software on Windows machines, I find the Quicktime viewer to be best for going frame by frame. Between that and my Samsung S4 at about 30 fps, it's sufficient to analyse our 4-meter trebuchet. Best of luck.

    If you haven't already tried it, a standard speed camera may be good enough. If you're in southern Indiana, USA, I'll loan you my tripod. :-)

    Those images are just thumbnails. If you actually want to see the modules, try http://www.brickshelf.com/cgi-bin/gallery.cgi?f=552922. 9v system, you asked in an earlier post if that pump jams, and I said no. At Brickworld Indy I found that if you run it faster than one ball per second, it will jam and start to break apart. The double sweeper is one I haven't seen instructions for. Is that your own design?

    Steve's GBC web page linked to above days "This started as a 'Ping Pong ball handoff' within our club (The Lafayette LEGO Robotics Club or LafLRC), and was combined with SMART's Crate Contraption to become The Great Ball Contraption ." There is a link to the SMART contraption discussion on Steve's page.

    The predecessor to the GBC was SMART's Crate Contraption, and it was all about moving containers of balls.

    Impressive! I sure wouldn't mind a longer video to see more of those intricacies.

    Nice touch including the balls in the barrels.
  8. ALittleSlow
    That's good work, as usual! Maybe you can divide and conquer.

    The photos don't show any useful detail, but the video is nice. I like the minecrafty stepper. The shooter looks very effective. Do you have more pictures of it, or, if you copied the design, do you know from where?

    I'm sure it's fine. I think he posted it on this forum earlier. I just wanted to give him credit.

    Owen, your advice is excellent, and I initially agreed with both the pain and sentiment of the above quoted statement. On reflection, though, I'm not so sure. Not everybody who buys LEGO sets builds something original with the parts. Sometimes they just enjoy the sets as they are. How much more true should this be for GBC modules, with their mesmerizing movements? You are right that nearly every GBC module will require some jiggering or tuning, but maybe that's enough for some people. Or maybe that's where they have to start. 9v system, I think one thing which would improve the responses you get here would be, in a word, reciprocity. Part of the idea underlying Owen's statement (if I can put words in his mouth), is that the GBC community, like most online communities, is built on the sharing of ideas and excitement. My observations of your posts here have been that you do lots of asking, but you haven't offered up anything yourself. Why not start by posting pictures of the GBCs you have built? I probably speak for all who have posted GBC instructions that we would be thrilled to see what others have done with our effort. Peace, Brian

    I don't remember if I posted this back in 2013, but I have just remade the instructions for my Wheel Lift 12x12.

    Thanks for sharing! The ball flow seems really good. You must all be pretty experienced GBC builders. I noticed a lot less ambient noise in this video than in most other GBC videos. Did you use a directional microphone?
  15. ALittleSlow
    Another way to get more height would be to use multiple stages. Slowing it down should improve the feeding efficiency and might reduce jams. Normally we control speed using a 9V train controller, but use could make a reduction gear set. A standard great ball contraption module will output one ball per second, so your ideal rpm would be 60. It will probably have to be a little faster to compensate for missed feeds.
  16. ALittleSlow
    Very nice! Very compact mechanism. Thanks for sharing your experience.

    If you are the member of a LEGO fan club that participates in LEGO's LUGBULK bulk order program, you might be able to get them in bulk. They are available in 2015 for, I believe, [edit] xxx USD each less than BrickLink prices. Oops. We're not supposed to publish LUGBULK prices. [/edit]

    I ran it for over an hour with to 5 to 50 balls and the pump never jammed. The feed mechanism did jam (the balls stopped feeding) once when I had over 30 balls in the hopper, but it cleared itself in under 2 minutes.

    My version of a classic. It's not special, but there are complete instructions. Enjoy. http://mocpages.com/moc.php/402738

    It is from the Crate Contraption by Gustav Jansson, David Schilling and Patrik. video: more images: http://www.brickshelf.com/cgi-bin/gallery.cgi?f=277534 There's an E-mail for Gustav at the end of the video.

    I've enjoyed (and subscribed, I believe) to your playlist. Because BrickWiki isn't a MOC site, I don't think I should try to create an exhaustive GBC Index there. I have been slowly adding exemplars, however. I could use help adding more or at least identifying the good examples. I think the good examples are those that are original, well-executed, and/or well-documented. Still I think it would be better if there were a place we could collaboratively build (and maintain) a GBC index. Maybe even as a theme, category or tag under some existing MOC bin?
  22. ALittleSlow
    White, unpainted balls are available on LUGBULK this year. The price is not yet available, at least in the US.
  23. ALittleSlow
    There are some examples here, categorized by mechanism: http://brickwiki.info/wiki/Category:Great_ball_contraption

    dr_spock Thanks for the report! What spray cleaner did you use?
