    I have a spare, dead M motor, so I might use the plug for that You could always just buy an extension lead, and cannabalise that... only a few dollars then

    Very cool concept, and excellent presentation! A lot of us in here would like more complex parts/sets from Lego Technic (a lot of people dislike the 1-part-per-step instructions of this generation) But I feel that while this is unlikely to be created by TLG... but it WOULD be an excellent candidate for people to 3D print themselves. Have you browsed Effermans' amazingly long thread? http://www.eurobricks.com/forum/index.php?showtopic=91294

    I ran it at a few lower voltages, and it still seemed to work OK.. but I'll test again tonight was funny.. half hour after ceasing my test.. I went back to my test bench... flipped the valve lever... and it still rose up - slowly! there was still enough pressure in the system to lift the arm fully - in about 10 seconds. RB

    Ok, so I dug out the pump I bought, and gave it a proper test... for 6V.. it's actually very powerful! (that's a train/boat weight that it's lifting with ease, in the video!) Ideally, finding a version that runs on 9V might be more practical... I found a website that lists the model, and it does say that this one might be ok at 12V, but with a lower current - I haven't tried it yet Googling 'Mini Pump 9V' yields quite a few results Anyway.. here's some pics.. and I think the video speaks for itself (esp compared to the fishtank pump! - Sorry Dr Spock! :) the nozzle/nipple on it IS slightly larger than lego.. but a soft lego hose connects just fine. Something like this could easily fit inside a decent sized Technic creation. I can't seem to find any record of how much I paid for this.. I seem to recall around AUD$30?

    Good video! I also have a motor (one from the Creator/Inventor set, with the clear casing, (47154) that has a gear, with a single broken tooth I have tried searching various hobby/online websites, for a similar sized gear, but it appears the Lego one is unique - all ones I could find have an even amount of teeth (12, usually), whereas the Lego one only has 11

    I think you'd be aghast at how my current lot of modules look right now... thrown into big tubs, during Brickvention pack.... most of them in a few pieces... ...but it's lego.. and I don't mind fixing and repairing bits here and there! I did make a long transporter box for my Truck Dumper module, though :)

    on a side note.. my 5yr old son who loves playing with motors.. made a hub, connected the 2 big rotor blades, and then connected to the old (2ndgen) 9V motor.. he then span it up.. ( took a while to get to full speed) I then stuck my hand it in... (to show him how Lego, used improperly, CAN hurt) OUCH! those blades have a lot of power in them, when spinning fast! Didn't quite draw blood, but left a nice dent in my hand, and stung for a while....

    agreed.. it's slightly awkward to transport I put the output stage on 2x2 tiles with centre hole, to make it easier to remove - will take a pic tonight.

    would be very happy to review PDF instructions + timing video.. I'm about half way through my build (Thanks Rebricker!! :) Didn't get it done before Brickvention, and will have some spare time on the weekend to check how I'm going I had the first half working.. but then, at one point bumped something, and knocked the timing out.. so I now have to go through everything again, and recheck. (the times when you get annoyed a build, and have to leave it, and return later, with more enthusiasm!) I'm also not sure why it's bumping the next bucket on the wheel so much, as you can see in the video... I also think I've got 'Bob' running backwards.. as he brings the bucket in fast, and returns slow... fun fun fun...

    I bought a small air pump on ebay (was actually advertised as ideal for technic pneumatics) to be honest, I haven't played with it much, but upon quick test, last year, seemed to work well - which is why it came up in my searches! I'll dig it up tonight and get details (maybe post a video) It was fair small... smaller than a D cell battery - possibly around C cell size RB

    ok.. here's my 'neccessary invention of the weekend' We had quite a few modules spilling balls... and of course, not all were nicely checkerboard tiled! ;) In fact, even some of Akiyuki's modules, when dropping the odd ball, were very hard to get out, while the module was running, thanks to his style of black frame base. So... while watching the grab and lift module (we had 2 of them!) for far too long.. it came to me... why not make one for picking up balls? So here's my quickie version 1 with a hook at the other end nothing overly complex, but it worked well.. allowing us to pick up balls stuck in weird spots, without disturbing a running module we ended up having 3 or so around the benches, and they got used by everyone. next improvement would be to have a pushbutton to eject the ball.. shouldn't be too hard to do! :)

    I've been hoarding rigid tube, in any long lengths and in any colour.. in anticipation of making a big rollercoaster There seems to be a lot in brown.. not sure what sets had a lot of them I bought a lot of those clips... but you also need a lot of these: http://alpha.bricklink.com/pages/clone/catalogitem.page?P=4085d#T=S&O={} (any of the 4 variants will work) I ran out of those (use for mounting to the structure), before I ran out of 76981 I did build a quick trial rollercoaster, but I was not confident it could stand up to a big GBC event, with people bumping the table occasionally
  13. RohanBeckett
    Yes.. we should have done a better job with the labelling... but I took the chance at every opportunity, talking with people, to say that all the modules along one side were originally built by Akiyuki.. I was surprised that quite a few kids already knew of him! "Oh look... there's the Ball Factory! I've seen that on Youtube!!" Aron (9VSystem in here), built the ball factory... it was 99.9% reliable.. he actually built most of it *before* the Rebricker finished his video instructions!. I think I noted once, where an arm somewhere slipped out of an axle, and had to be reattached.. but that was about it quite impressive for a 17yr old who lives out in the sticks! ;) His Invisible Lift was equally reliable.

    I think there were 4-5 in the tubs under the tables! I actually didn't get a pic of my picker-upper.. so will have to take one at home I too will be looking at how to improve it too! :)
  15. RohanBeckett
    hah.. thanks :) will put up some other detailed pics/videos of my modules a bit later.. Yes.. brought the Dynamo... and meant to label everyones modules, but didn't quite get around to them all! A couple of things that would haven been helpful A label with Name of Module, and owner on EVERY module (and who it was influenced by, eg Akiyuki/Torso) A Start and Finish marker! You won't believe how many times we got asked 'Where's the start?' - and how many times I answered - 'So you tell me.. where's the start of the earth?.... it's a circle!' and I'll take a pic (unless CaptainOwie) beats me, of my invention of the weekend - Ball Picker Upper Tool - which made life a LOT easier, when collecting balls stuck in tricky spots RB

    we did have a lot, during the day.. this video was filmed near packup time, and we'd already cleared most balls out.. I threw a handful in, just to film Thanks! Aron (9V System), and Steve (Onemorerobot) have been very busy lately building them! I need to get off my backside and finish tilted rotors! :) would have been slightly funny, if I'd finished my ball factory too... and if Steve had brought his down... we would have had 3 of them in one exhibit! Would be interesting to know from some of the other big layouts around the world, how many non-functioning modules they have at any one time. We planned to have around 50 modules.. but ended up with 40-43 at any one time in operation. I'm yet to properly unbox all my modules, and see how much ABS dust I have all over the place!!
  17. RohanBeckett
    Yes.. and it's a very reliable module too... ran all weekend... the only slight issue, is that sometimes (even with a full hopper), it only seems to push 4 balls up.. ..and sometimes.. when it does get 5... the 5th ball slides into the 'hand', and bounces out.. spilling But other than that, mechanically, it's perfect
  18. RohanBeckett
    Well.. we had a great display at Brickvention 2016, in Melbourne this last weekend One day of setup, and 3 days of running/maintaining it. Plenty of good compliments from the crowd, with lots of kids pointing out "I see a ball there!!" - to our numerous escaped balls! Overall, we had 14 members in our team, several of whom travelled interstate! We had around 42ish modules (a record for Australia!!) give or take one or two that were in and out of repair Quite a few Akiyuki modules, some who were very reliable (I don't think I saw the Invisible lift have any issues in 3 days!) I'm quite proud of my green-truck dumping module.. a semi original creation (borrowed the idea from another mechanism I saw) , but had no idea if it could run all weekend... and it did! Uploading a Gallery of photos soon.. will edit my post later. RB

    I did a timelapse build of this a while ago (can't believe this was so long ago! - uploaded in 2010.. but actually filmed in in 2008!) it's been in parts for many years.. but recently, I collected all the parts.. I should do another video... and see if I'm any faster at building it! Note to self - don't start huge builds at nearly 11pm!
  20. RohanBeckett
    Curious as to why your instructions have the one-way catch on it (red)... I found this module didn't care which way it ran! I've recently modified mine, so that one end of the catch-ramp can be angled the other way, to recirculate balls back into the hopper... since it's so effective, it clears balls too quickly before people get a chance to see it! :)
  21. RohanBeckett
    Great work, as always! But I knew I'd seen something before.. and after 20mins of google-fu... found this.. Definitely different to yours.. but does still create a programmable matrix of balls
  22. RohanBeckett
    But can it handle 1 ball per second?! ;)
  23. RohanBeckett
    built the hobson's coupling last night.. left it on the kitchen counter, for Mr 5yr old to discover in the morning... wake up with 'Cooool..... but it sticks a bit... oh.. it's this 6 axle jamming in the hole.. you have to poke it back a bit' I expect to come home tonight, and find it motorised... nice to have a little engineer/problem solver in the making!
  24. RohanBeckett
    I have the big beige one, with the big green/red button.. it's pretty cool - you can 'record' the movements of the drive motors.. and then play it back, once/repeat/loop quite an interesting creator set, it came from...
  25. RohanBeckett
    this looks like something Isogawa would build! might try to use it in a GBC or something - even if it's 'just for show' (which, technically, what most GBC's are!)
