    I decided to finally make some renders. I hope I used the most current file. You can get much larger versions at my Bricksafe.

    Your photos are so good that making renders doesn't really add anything, but I did it anyway.

    I couldn't resist. This was actually pretty tricky to render because I had never defined some of these rare colors in POV-Ray before.

    Wow, that's a great looking Jeep! Excellent work.

    Your observation is well known to LDraw part authors. That's why they build up parts out of "primitives": subsections of parts that are repetitive. Each of the four you mentioned is a primitive which can be used to build up a more complex part.
  6. Blakbird
    Yes! I recall @crowkillers talking about this. The pin is not exactly the same length in each direction so it sticks out a bit past the 2L side. This can sometimes interfere with gearing so it is important to position it in the other direction.

    No. Step 48 installs the top supports, step 49 installs the bottom supports.

    This certainly doesn't belong on the Technic forum. Moving it to General.

    I can think of a couple of possibilities. My first thought was that you were not logged in. If you drop a PDF file into a window it will simply open the PDF file. If you are logged in, it should be running a script though and should work as long as you drop it directly into the upload rectangle, not just anywhere in the window. If it is still not working, it may be that your browser does not support the scripting language. What browser are you using? Another possibility is a corrupted file. Does it work OK on your computer? You can always contact Nathan, the owner of Bricksafe. He is pretty responsive. If you get desperate you can send the file to me and I will try to upload it.

    I actually kind of hate this part. While it does open up a lot of build possibilities, it can also be really difficult to install. This is partially because of the stiff plastic used and partially because it rotates out of the way and has little to hold onto. My favorite part is probably this.

    What seems to be the problem with Bricksafe? Let me know if you need help.
  12. Blakbird
    Agreed! This model is actually very tricky. Every single part is at a weird angle and it is not at all obvious what anything is supposed to do until you are done.

    I like your solution. Looks really robust. aeh uses a wonderful Geneva mechanism in his Pen-dragon drawing machine that you should check out. Akiyuki also uses an incremental motion device in his Ball Factory GBC for 1/16 motion of the bucket wheel.

    I think you are referring to djm's original draft instructions. The final instructions I published all have the gears meshing perfectly. There are other differences in design between the two versions as well. Edit: You may have downloaded an early version of my instructions. My original idea to use train windows didn't work and I updated the instructions, at the same time fixing those gears. Make sure you get the latest version. This has happened with a few parts, including DBG bricks in general.

    Not every seller has a minimum buy. In my experience, Bricklink beats eBay on price almost 100% of the time even with shipping. The last time I bought LEGO on eBay was 2004.

    I see that this model was blogged on The Brothers Brick. Too bad they didn't mention that instructions are available.

    Keep the chassis rails as far apart as possible both in the horizontal and vertical planes. Stiffness varies as the cube of distance, so a little distance makes a big difference. Never build the chassis only one stud thick. Use as many right angle parts (L-shaped liftarms) and diagonal braces as possible. Use frames (5x7 and 5x11 light gray frame boxes). Use friction pins (black) as opposed to frictionless pins (gray) or axles to assemble the chassis. A chassis built from old studded parts is much stiffer than a studless chassis. A combination of both gives you the best of all. Check out the instructions for 8466.

    Yep, that would be the crane, 8094_4. http://www.technicopedia.com/8094.html#4

    The render is completed and exported using H264 codec. The original file size is 162Mb, but of course YouTube messes with it. The flickering is noticeable if you know what to look for, but is not bad. Some things to notice: I like how the start/stop of the motion is gradual. For example, the wheels don't just go from stopped to full speed. They ramp up gradually giving the illusion of inertia. U-joint crosses are hard to get right. These are perfect. The way the spring compresses must have required a new version to be generated for each frame. Good work! I'm not sure if the fan belt actually moves. With no texture, there is no way to tell. The Ackerman correction on the steering is noticeable at full lock. The way the ratchet pawl is visualized on the seat recline is awesome. I suppose this video would benefit from some captions to explain to viewers what is happening in various sections. This is a perfect way to demonstrate all the functions of a model.

    From 1977-1981 the gray pin was the only pin. The black friction pin was introduced in 1982, but it did not replace the gray version. The frictionless gray pin still exists but it is only used for rotating joints, not for structural connections. So if your definition of "new models" is after 1982, then you are right about those black pins!
  21. Blakbird
    I certainly have over a million parts, but they are pretty much all assembled. In loose parts I'm sure I have less than a thousand if you ignore pins. ReBrickable says I have about 40,000 black pins, and about 100,000 if you include all pin types.

    Sbrick+ supports WeDO sensors.
  23. Blakbird
    Yes. You can control MANY Sbricks at once. I forget what the limit is, but it is more than you would ever use. I have done as many as 4. As many as you want as long as you stay under the current limit. If you are using the full power of a motor, then probably no more than 2 XL motors. you might be able to do 3 L motors and 4 M motors. Yes. When you make your control profile, you can map as many channels to same slider (even on multiple Sbricks) as you like. For example, Madoca's Icarus supercar uses 2 batteries and 2 Sbricks with 2 drive motors so they are each on a separate battery for maximum power. Works great with a single slider.

    Good point! I will probably upload the final file to YouTube for easy access, but I may also put a downloadable Quicktime file on Bricksafe. It will be huge, of course, but the kind of people who want the extra quality won't care. The other option is to render at full HD 1920x1080 like Roland intended, but that would take twice as long. Maybe I'll launch that render next time I go on vacation. 2500 frames done so far......

    One thing I just noticed is that YouTube won't display the video at it's native resolution of 1600x900. It resamples it at 720p and therefore it is not as sharp as the original file looks on my screen. I'm not sure there is anything I can do about it.
