There are electrical multiplexers as mentioned, however there are also many types of mechanical multiplexers. The idea behind this is to use fever motors to do more. The advantage is the reduced weight and the disadvantage is the increased complexity and lower flexibility. For example, you can control both tracks with one motor. However instead of one motor ...

This would push the pins up and down like a normal key would. Here is the basic system. I don't have time to build to whole thing but this resolves the main problem and proves the feasibility. The main problem was to reproduce the pins system with LEGO bricks since each pins needs to have different lengths. Early in this project, I wanted to have a '...

I once had an acquaintance who worked at Lego as a product designer (I don't remember his exact title). His job was, simply put, to come up with new sets. There are some general constraints – balancing the different Lego worlds/themes (contemporary, pirate-age, Star Wars, Harry Potter, etc.), hitting certain price points/box sizes (limiting the number of ...

There's a nice interview with LEGO Designer Mark Stafford on The Brothers Brick: From LEGO fan to LEGO set designer - the Mark Stafford interview The basic process was: The position was advertised, and Mark's portfolio was sent in. He was then invited to a two day recruitment workshop along with a number of other candidates. I've also read other ...

As far as I know, designers work mostly with bricks only. They do have a desk and a quasi-unlimited supply of parts (which I think is actually not too exactly close to their desks), and usually use their imagination the same way a fan does. Something which fans don't do however, and which designers must do, is keep track of the price of the model they're ...

In addition of the already mentionned Blacksmith shop and the three first LEGO factory sets (5524 — Airport, 5525 — Amusement park and 5526 — Skyline, combined from the 10 winners entries of the contest), the following sets have been designed by fans: 10190 — Market Street was designed by Eric Brok. Eric sadly passed away a few month later. 10183 — Hobby ...

There are some Books available that include building-instructions (i don't own one of these, but i would choose the most current): The BrickGun Book (Book released in 2013, site has occasional updates as of December 2018 with more instructions) Badass LEGO Guns (December 2010) Weapons for LEGO Lovers (February 2009) as Joubarc said the at least 4 years old ...

Hexagonal symmetry and angles in 15, 30 and 60-degree proportions are scarce among LEGO elements. I think the smallest single piece that approximates a six-pointed star is the basic flower: I myself don't practice freelance brick modification, but someone with fewer scruples might easily trim one of these into a 6-pointed star shape. Another piece that ...

Mindsensors sells third-party parts that are compatible with the NXT. They sell several motor drivers and multiplexers, for use with NXT motors, RCX motors, hobbyist servo motors, or by sending commands to a PF motor remote control receiver. HiTechnic is another such company, and they likewise make a device that sends remote control signals for PF and ...

Currently in use: Stud and "antistud" (diameter 4.6mm) Longer studs (Minifig torso) Minifig legs 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 ...

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 ...

There are two non-wireless ways that I know of. One of them, (which is better most likely) is to use a Mindsensors Motor Multiplexer (Motor MUX for short), which allows the use of all motor functions and splits one port into several. Note that each multiplexer requires an additional battery box, making your robot heavier and less compact. Each multiplexer ...

I thoroughly enjoyed National Geographic's documentary - Megafactories - LEGO: It's one of the most popular construction toys in the world. In the age of unprecedented competition for their attention - from videogames to TVs to countless activities - children still spend over 5 billion hours a year playing with LEGO bricks. But building simple modular ...

It's difficult, but not impossible. A rigid axle turning at the centre would be mechanically simpler. As my crude drawing illustrates; I would place a 24-tooth gear over the 2x4 wheel axle. A 8-tooth gear is optional but will provide finer control over the steering. The two teeth gears can also be replaced with a pulley gear. This technique however will not ...

If I recall correctly, it started in 2007 with LEGO's initiative called LEGO Factory, where fans were invited to compete in designing models using LEGO Digital Designer. The winners would then have their entries made into the very first fan-designed commercial LEGO sets. Today, LEGO Factory is superseded by Design by Me. It follows a similar concept, except ...

Pierre Normandin followed the path of "well-known AFOL doing tremendous sets" to "AFOL invited by LEGO to participate in secret projects from time to time" to "Actual LEGO designer" (I'd like to say "demigod", but he tends to frown at me when I do that). He was also one of the first groups of LEGO Ambassadors. But in any case, the most important criteria is,...

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 :) — https://twitter.com/Spider_Sam_LEGO/status/1037914372897681409 Ah! Do both the colour and the shape (studless vs studded) ...

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....

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 ...

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 ...

Everybody else has pretty much said it all, but there is one more thing I can think of. The IR Link Sensor can communicate with Power Functions, RCX, and trains. So you can use three NXT motors, plus, say, two Power Functions motors. (Only the NXTs will have rotations sensors, obviously.) If you already have some PF kit, you will only need the sensor (£40)...

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: ...

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 ...

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 ...

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. :)

What about the 75930 Indoraptor Rampage for an almost timeless mansion? Without the raptors it is not too expensive. The 10228 Haunted house could provide a good basis for a rebrick of a nice mansion on the hill just outside of your city. However, this one is ALWAYS expensive, as you probably know. For many nice little ideas for everyday items and a MOC ...
