I've come up with five different ways to make a micro security camera that look like your reference image.
I'll run through the different methods in the image above from left to right 1 through 5.
Far left camera 1
Tile, Round 1 x 1 in black (the lens), Brick, Round 1 x 1 Open Stud in white (camera body), Plate, Modified 1 x 1 Rounded with Handle in white (...
It sounds like you're trying to implement a fairly simple bell mechanism such as this one:
You can certainly do this using some string and the pulley element that you mentioned.
I'd recommend tying the string to one of the holes in the pulley. Something like this worked reasonably well for me:
Here it is in action:
You'll likely want to do something to ...
While there could be various approaches building studless the easiest one would be with Tile, Modified 2 x 2 Inverted. These modified tiles have studs on one side, which fit under bricks and plates, and smooth surface on the other side.
Here is a prototype which features equal 6-stud (or 30 modules) long sides. Parts can be changed upon availability, but it ...
If you're after a simple collapsible solution to reach those items just out of reach, you can start with the following setup:
You can extend this for quite some way, and use longer bricks or beams throughout if you wish.
To finish it off, I'd use a couple of longer bricks with some additional plates on the end to act as fingers, and add some handles (via ...
Some of it may be your own perception changing, such as a room you remember being big when you were a kid, but which you find small as an adult. So when you perceive bricks as being softer, it could actually be that they aren't, but that your perception changed. (If you were to walk barefoot on LEGO bricks for one hour per day, your feet would eventually ...
Just to add a little to the answer by TheBrickBlogger, the blue piece holding the purple 1x1 slope is likely this one:
Here is a really simple example of one of the many ways this can be accomplished:
The hollow stud allows positioning to be "jumped". Hope this is helpful :)
Currently in use:
Stud and "antistud" (diameter 4.6mm)
Longer studs (Minifig torso)
Minifig neck and head / accessory (eg backpack) - also compatible with studs
Clip and bar (in a way, similar to stud, but with diameter 3.2mm)
Wheels (3.2mm axles)
Flower connector (similar, but even smaller, present in a surprising number of parts, including ...
I can't definitively answer, but I can say that this has been a common observation around the late 1990's and early 2000's-- nothing to do with Chinese manufacturing.
I personally made the observation when comparing construction in large-scale creations in 1999/2000 and later in 2005. The large scale creation in 1999/2000 was a very large building, ...
I asked one of the set designers at LEGO, Samuel Johnson, on Twitter. Here is our conversation:
This to aid in the building flow for children aged 5 and up. Easy to spot on the page, easy to find in the pile of bricks :)
Ah! Do both the colour and the shape (studless vs studded) contribute to ...
The black cheese-slope is attached to the stud below, and the purple cheese-slope is attached to the upside-down stud above it. The two cheese slopes are not attached to each other, but are held in place by the studs and the other pieces around them.
Cheese-slope techniques have been extensively researched by LEGO fan Katie Walker, who is well known for her ...
Perhaps Minifigure, Utensil Ring 1 x 1 will be a better fit as it is slightly larger than a stud, while life preserver is 3-4 studs in diameter.
Here how it looks when attached to doors you've mentioned:
You might want to look at Flex System tubing. It comes in a variety of lengths (including 6L and 7L) and doesn't have a stopper.
For what its worth, this is the technique that Jamie Berard used to create the downspout on the apartment in the Pet Shop:
As mentioned in another answer, there are dedicated pieces for this now.
But... 6x6x6 cube is plenty big enough to have a stud-reversing construction inside, then the bottom can be a simple 6x6 plate with regular smooth tiles.
For example put some of these inside the cube:
Burning oil is the easier of the two, since the basic flame elements
can connect into a realistically looking stream of liquid fire:
Depicting individual arrows is a lot harder due to the absence of a single arrow piece (aside from the proportionally way oversized harpoon piece), and adding a flame piece is even harder. Your best bet would probably be ...
I built a similar model to Zhaph's claw arm but with beams and a basic claw attachment:
360° Animation, Demonstration Video
I had a few problems operating the claw when I built it again with real bricks. If you collapse the beams too far, it can be difficult to open them again. When you try to pick up items with your tool, you also have to anticipate just ...
Here's the simplest way that I can think of to stop the vehicle at the finish line. You'll need basic LEGO Technic parts and a good length of lightweight string or thread.
Create two reels for the string. One should be connected to the wheels and the other may turn freely. Wind all the string onto the reel which can spin freely and attach the other end ...
Plastic pieces will become harder over time. Not sure why, but I think it is that the substance that were added to make the plastic a little softer evaporates over time.
I have been told that the people designing sets for LEGO never use pieces older than 2 years. This is because harder pieces will have more clutch power than softer pieces and because of ...
I don't think there's any LEGO set for which the age target goes any further than 16+.
Within the 16+ range, you'll find several sets, mostly in the exclusive sets (series 10xxx): mainly modular houses and some Star Wars UCS sets. Usually these are sets with a high parts count and a price to match.
There's a functionality to filter sets by age on shop.lego....
The first photo on this page shows the model Andrew Lipson made.
The photo is taken under a such angle in respect that the different parts line up in the photo, to get the desired effect.
"Waterfall" used a combination of specifically angled photographs, coupled with some post processing to remove the overlapping elements:
OK, let's come clean. We ...
Going for contrast to help you build?
This is probably the primary reason most of the time.
One Eurobricks user once said they asked a set designer about it, and they confirmed they do it to makes it easier to follow the instructions:
I had an opportunity some time ago to talk to a designer at TLG, and he told me that they use other colors to make it ...
This piece is only two plates high, to have another piece in here you would need to stack two plates, which would
make the total pieces count rise, or more expensive
might be more difficult to tear down by hand
probably less sturdy (with a piece on it acting as a lever stacked plates could pry apart)
Sets designers are under constraints for both piece ...
1989's Eldorado Fortress from the Pirates universe had torches made from part 3959 with a single transparent stud on the "top", with the entire assembly pushed into an Erling brick.
You can get a similar effect by clipping a lightsaber hilt piece to the wall or putting it onto a post. Just add a suitable flame piece (or simple stud) coming out of one end. ...
The "wheels" are really the hubs, mostly from the various Speed Champions cars among others.
The inside of the wheel takes a standard stud, so you should be able to use:
Plate Modified 2x2 with Pin Hole
Technic Pin 1/2
Wheel Cover 5 Spoke
Beyond the primary question of how to build these particular wheels, there are a few common themes among wheels and ...
Donny Chen made a LEGO piano that I believe is just large enough to play. Details are available on LEGO Ideas. You can watch him show it off in a video from Brickvention 2019. He has it motorized in that video.
From your comments, it sounds like you are interested in not simply having a piano with keys that can move, but one that actually emits proper sound....
As there are more and more LEGO fans who become designers, some of them are already well known from the community and are very dedicated to fans, going to events and the like. They are actually just regular people and always have an amused look if you treat them like they have ascended to godhood status or something.
A few of them in no particular order:
I was able to integrate this into a research project applying context free grammars:
This is not a polished software package, and the design is a bit esoteric given that I started with the goal of applying context free grammars to a practical problem. Hopefully there's something in there that may be useful to someone. :)
