Knight3

Although not a castle set, I would suggest you to get Rivendell (10316). Perhaps the best set ever made, imo. It looks great with the medieval theme. Also, the new Snow White (43242) set looks really really good together (with others)! Edit : +1 to the upcoming Dungeons and Dragon set too!

As the title goes, what are some of the best MOCs? And what are the must build MOCs?

안녕하세요 :) Could I ask you what themes you have collected? Like Technic, Star Wars, etc. I'm also interested in this post, because I too have a big collection (around half of what the OP has; mostly technic and some Star Wars) - most of them are lying in my granny's home, so I have not yet decided what to do. "If push comes to shove, I will put it out with the recycling" - if you ever decide to recycle - please give it to me! :)

I'm currently doing a postdoc, in my home country and I decided its time to build something useful with what I have at the moment (Unfortunately, I have left a lot of legos at my granny's place). I would like to build a lego printer out of EV3. (Edit : I can also use the Powered Up system as well) I pretty much have an idea on how to build a physical (lego) printer - one motor to control the X-axis, and the other motor to control the Y-axis. (We could add in another motor to just control the pen, but that's optional) And if I want to print something, like letter "A" - just program it to make three line strokes, so that it looks like an "A". Well, that is the gist that I have. However, I can't wrap around how to make the lego printer to actually print an image file, like a real printer. Of course, after this, I would love to move on, to make a 3D printer as well. (I'm good with Python and other programming languages like Java, and am familiar with algorithms. And I heard ev3dev is good? Also I am familiar with html/css/javascript - just know how it works. I'm not good with it though) So here is my question : How do you make an interface between the lego ev3 and the computer, so that the lego printer can actually print an image file? How does it work? What are the steps involved to make one?

Yes, I did read it before buying the set - that was one of the best reviews I've read! Surely, it helped alot while building. ^_^

Hello everyone, Its been 4 years since I started playing with Legos once again. Starting from NXT, I've bought lots of sets - 9397, 8110, 9398, 8043, to name a few. Even if I didn't post anything, I've been a fan of this site. I've been busy with my studies then, so I've disassembled the pieces in the hope of building something cool like everyone. Getting used to the studless system was hard. I realized my knowledge of lacking, so I read Sariel's book and Lego Technic idea book. (Skimmed through, as I didn't have much time back then.) I took a break from legos starting from 2014 - I had to go live in my grandmother's place (So I had no choice but to leave most of my legos at home, but I took some important parts like Pneumatics/Power functions/NXT/beams, etc). Recently, out of the blue, I started collecting it again - I've bought the EV3, 42053, 42049, 42043, 42055, and a race car which had a pull back motor. Anyways, while building, I always seem to have this problem of not following how it works. I'm not talking about easy sets like 9398, or 42049. Something like 42043, 8110, 42055, 8043 - I just have trouble understanding the complicated gearbox. I try playing around with what gear is connected to what, and turn the axles to see how it will work, but as it becomes gradually more complex, I lose sight of what happens. So, all I do is, turn on the motor, and see how it performs. I turn on the other switch. Then I see how it all rotates like magic. "Ohhh!" I say that, but am not satisfied. Since I can't recreate the inner mechanism, I've not understood it clearly. (Yes I'm talking about the ones with the 16 tooth gear with Clutch, like 6542a and 18946 (rebrick ID)) So my question is, 1) How do you guys deal with the gearboxes? How do you understand it? Is there an easier way to do so? 2) How does one come up with such a thing? And if you could give me any other tips, that would be helpful! Thanks in advance. :)
