    Very compact - I like that (remembers me of my "Shrink-o-Mania": make it smaller, make it smaller). And well shaped for this size
  2. Leonard Goldstein
    Very nice! And I like to see more non-vehicle-solutions
  3. Leonard Goldstein
    That is great! I hope you put a cuckoo into it (maybe you can use one of these as a replacement: 2546, 98388, 92084). Following

    Many thanks to @Jim for front-paging my crane As I wrote above I am away from my LEGO right now and it will take a while to bring more information and the video to this topic. Anyway [TC13] is catching a lot of attention right now (what a beautiful contest and some very interesting topics have been started ). So I will work on the LDD-file of my crane during holidays (and the video when I am back home) and I'll be back here when [TC13] is finished. Regards Leonard Goldstein

    Hi mocbuild101, first a (newer) smartphone is not that bad: for example I used my iPhone 7 for the indoor videos of my Mini-Truck: And the iPhone offers a slow-motion-mode with 240 pics/second. Important thing of course is to use a tripod. I got a simple one from amazon for about 35 Euro and it includes a bluetooth remote control (no need to touch the phone => no blurring). But although I am quite happy with my phone, it has its limitations. There is only a digital zoom, no optical (I know, the 7+ has one). And you have to preselect the zoom. No zooming while filming. And the very small objective cannot be as rapid as a big one. That is why I use a Sony Camcorder in addition. It is a little bit older ("HDR-PJ260"), but it makes a great job. Most of my outdoor videos were made with it. Regards Leonard Goldstein

    Hi Milan, thanks! Of course this idea is not new - googling "Lego life hacks" gives you about 1.500.000 hits ... Maybe the mission should be a little bit more specific. Or the rating depends on how much time (or money) the device can save. Regards Leonard Goldstein

    Yes, exactly. Of course it would be easier to use some more clutches, but the ambition with this project was to make it a C-model. And there where some other problems: the 42055 uses only one worm gear. And this is needed for the winch (self-locking effect). All other functions had to use "normal" gears (lots of them ...) Regards Leonard Goldstein Thanks! Yes, 42055 is a fantastic set for c models. And in relation to the number of bricks it is quite cheap. I got mine for 175 Euro - less then 5 Cent per piece! Regards Leonard Goldstein

    You noticed it Of course you're right: there are only 4 clutches included in the 42055. The remaining two functions are realized "old school": an axle with gears is moved to mesh the gears alternately. Regards Leonard Goldstein

    Hi JGW3000, thanks a lot I think the video will be done in the second week of 2018. The sidewalls of the engine house can be opened - then you see hundreds, nay thousands of gear wheels ... I promise to give a look at them in the video. I also work on an LDD-File, but this is quite tricky. There are a lot of tolerance problems, especially in the gearbox. Regards Leonard Goldstein

    Like others said: prizes are not that important - the contest itself is the kick And of course having a lot of fun and an animated discussion. May I suggest a mission for the next contest: build some object of daily use. Here is an example: This phone holder for an iPhone 7 is by far my most played MOC It works much better than the original that came with the car. "Daily use" gives a lot of room for interpretation - and in most cases it would be a "non vehicle" like @Jim suggested some post before. Bye Leonard Goldstein

    Hi everybody, my last few mocs were quite small - but not this one ... It is a Luffing Crane with a container claw - a perfect fit to 42078 Powerfunctions: 1. Moving forward/backward on the rails 2. Rotating the superstructure 3. Moving the boom up/down (level of the payload does not change) 4. Moving the claw up/down 5. Rotating the claw 6. Open/close the claw All functions are powered by one XL-motor. Function and direction is preselected by six clutches and there is one main clutch that activates the selected function. The main clutch works much smoother (it is a friction clutch) than the Lego dog clutch 18947 and allows precise steering. This is the key function of the model: the container claw. Three ropes, three functions: up/down, rotating, open/close The rigging is quite challenging Here is the engine house with 6 sticks to operate the clutches. The red read lever on the right activates the friction clutch. The shovels work as counter weights (with some old batteries inside). The trailer can carry two 42078 containers and has suspension with torsion bars. The container in the background looks a little bit funny as it is made of tracks ... And now guess what this is: ... these are the leftovers from 42055. Yes, yes, yes: this is a C-model It is using about 3000 bricks. Can you imagine to run out of black connector pins with a 42055 on the table? If you are wondering how these claw functions work, have a look at this topic: Many thanks to @kolbjha; I adapted your idea using a closed loop to open/close the claw. My crane uses the closed loop to rotate the claw and an additional rope is used for open/close. Well, that's it for today. I know you want to see a video ... please be patient. I will be away from my Lego for a while and of course I want to pick up the 42078 before I start the shooting. At least you can see the pics in higher resolution on my Bricksafe page: https://bricksafe.com/pages/Leonard_Goldstein/luffing_crane Bye Leonard_Goldstein

    Hi, my dream would be a PS3 (or higher) compatible receiver. This would solve a lot of problems. Advantages: game controllers are everywhere available for a little money the bluetooth connection of course works much better than IR these controllers offer a lot of channels, some of them proportional with a hardware controller the haptics is by far better than with any touch screen device (as I mentioned in my latest topic) And of course I would like a powerful replacement for the buggy motor Regards Leonard Goldstein

    What a beautiful set - must have No powerfunctions inside, but I think this is an advantage: if there is no need for updates it would be boring. The 42030 came completely motorized - nothing left to do ... so I built it, played a little and since then it stayed in the shelf. And I do like this mix of system and technic. Seems like Lego had to right a wrong from the 42070 (which really looked unfinished somehow). I will order it as soon as possible Regards Leonard Goldstein

    Thanks again The cable routing was indeed challenging. On the first try I wanted to place the sbrick between the seats inside the cabin. This did not work at all - the whole cabin was filled up with cables. But at the backside there was some space left between the two M-motors (see the picture above). I put the sbrick upside down between these motors and with a little pressure all the cables could find place. They are gushing a little - what you can see on the last pic of my first post. This is a familiar problem: my Highflyer of [TC12] was even worse ... The woodpicker is great fun to play with. Very powerful and the steering works great. In comparison to the 42065 I think it would win the race. The only thing I do not like so much is the handling via touchpad. The feedback of a hardware device is missing. Please Lego: there are so many cool solutions (sbrick, buwizz) out there. Why not developing an OEM-solution to update this IR from last millennium? Regards Leonard Goldstein

    Many thanks! As you can see in the picture below there is almost no framework inside - the two L-Motors are the framework. And the subtractor (my own creation ) is a little bit special: first there is no differential to split the power flux instead of this there is a separate motor for each side (gives more power, too) the differential of the steering is arranged in a special way: one bevel gear is connected to the steering motor this means if you drive the housing of the differential the opposite bevel gear is running at a double speed to compensate this the housing is driven by a 12T (=> 12:24 gives halve the speed). As a result both tracks run at the same speed as the steering motor is off. There is only a little disadvantage: when steering the tracks of course run in opposite direction - but not at the same speed ... (does not really influence playability ). Regards Leonard Goldstein Thanks, I did my best It was quite tricky to build some bodywork around all this powerfunctions (there are more PFs inside than in the 42030 ...) And there was another problem: the two driving motors have to run in opposite direction. But they have to be connected to the same channel (as there are only 4 channels). This means a switch (8869) is needed. This switch is soooo big and there was absolutely no space left. The solution was easy: make the switch part of the interior and now it is some kind of a central console. Regards Leonard Goldstein

    Hi, another Mini-MOC for you: here comes the Mini-Skidder This little thing is very powerful as it uses 2 L-Motors for drive and a third L-Motor for steering. Watch the video: On my brick safe page you can find the pics in higher resolution and of course an LDD-File: https://bricksafe.com/files/Leonard_Goldstein/woody_and_the_woodpicker/Woody-Woodpicker_V02.lxf Let me know what you think Regards Leonard Goldstein

    Hi @mocbuild101, thanks for sharing these safes, they are really great! Of course the little one is my favorite - this is Shrink-O-Mania developed to perfection Suggestion for the next contest: build a safe that cannot be picked by members of staff Regards Leonard Goldstein
  18. Leonard Goldstein
    Thanks! And have fun building the "Highflyer". If you have any questions don't hesitate to ask. I will keep my Highflyer in one peace except the electric parts - as I need them for some Mini-MOCs Regards Leonard Goldstein

    Hi @Oliver 79, your suspension system made it possible to have 2 studs of travel at this scale As I promised here some fotos (I added some mirrors as you can see) ... ... Cockpit and openable doors ... ... 4W-steering in action ... ... and the link to the LDD-File: https://bricksafe.com/files/Leonard_Goldstein/mini-truck/Mini-Truck_07.lxf Well, that's it. The next Mini-MOC is in the pipeline Regards Leonard Goldstein

    Hi @efferman, I really like your HX80 And the combination with your heavy duty moduls is a perfect match. The video with the on board camera is pretty cool - although I would like to see the whole train from some distance. Did you try to back up into a parking space ? Must be challenging Regards Leonard Goldstein
  21. Leonard Goldstein
    Yes, please! And please let me know when you're done I saw a video on youtube to this subject which really fascinated me:
  22. Leonard Goldstein
    That sounds interesting - any pics?
  23. Leonard Goldstein
    Hi @janssnet, this is really cool, well done At the moment I am a Lego-purist - the only third party parts I use is an S-Brick. Your MOC makes me feel missing something Regards Leonard Goldstein
  24. Leonard Goldstein
    Hi @Horace T, thanks - that is the advantage of this small scale: it looks so fast I hear a strange little voice every time I build with Lego: "Make it smaller, make it smaller". I think I suffer from Shrink-O-Mania ... Regards Leonard Goldstein
  25. Leonard Goldstein
    Sorry Of course let me say a special "thank you" to @Milan (Did I forget anyone else?) Regards Leonard Goldstein
