There are a few pdfs listing the linear and angular ratios, can't find them right now. Enjoy your google fu.

[1] and as programmers I'm sure you enjoy that ;)
But the fact that THREE flat pieces equaled a standard height piece drove me nuts as a kid. WHY NOT TWO OR FOUR?
This fact is extremely under-appreciated: the Lego system works the way it does because they have attained truly astounding tolerance control in a cheap injection-molding process. I remember a couple of years ago when a small startup promised a Lego-like replacement, but themed for girls. The hype got them plenty of sales, but the poor fit of the pieces meant lots of disappointed customers.
>Marvin Minsky, the MIT scientist who helped pioneer artificial intelligence, has even said that “the decline of American inventiveness” can be traced to the rise of Lego, arguing that by becoming the most common construction toy, it’s pushed out construction toys like Tinker Toys and Erector sets that can get kids building simple machines.
Whoa, those are some names I haven't seen in a while but did grow up playing with. Tinker Toys in particular. To me, the criticism isn't fair - those were toys and learning tools from a prior generation. I'm pretty sure the only reason I grew up with Tinker Toys was because I had a Grandmother who grew up during the Great Depression and was of the generation that enjoyed them. My Parents much more embraced Legos, and, quite simply, getting bags or bins full of used, miscellaneous bricks at garage sales was a huge creativity boost. Then, later, turn around and sell or donate them. Rarely did I see Tinker Toys or Erector sets around. Technics seemed to bridge the gap between Legos and higher-level engineering / complexity / use of motors.
What does feel important about Legos & playtime, to me, is the manipulation of 3D space, coordination, and dexterity training. There is no such replacement via a 2D screen, and 3D / VR or AR aren't even close. The ROI on play time, age appropriate, with Lego-type hands-on exploration is worth keeping in mind. No batteries. Easy to clean. Hard to break. An Occam's Razor of developmental toys.
The pieces are almost all generic, and closely model their real-world mechanical equivalents -- beams, pins, gears, axels, motors, linear actuators, switches, battery power supplies. There a great book exploring all the technic fundamentals: "Unofficial LEGO Technic Builder's Guide" [1]. It covers concepts like leverage, torque, gears, gear ratios, differentials, suspensions, transmissions, etc.
Throw in the fact that technic electronic components (motors, lights, sensors) can be driven by code (eg. scratch on a rapsberry pi), and I can't imagine a better learning toy which is initially so approachable, and yet has such a high ceiling for advanced learning.
If you want to see what incredible creations are possible in the hands of the masters, check out "Incredible LEGO Technic" [2].
However, I see many kids building one model, and then sitting it on a shelf as something they have made. What a waste of Legos...
Basically, how I can find start-sets of LEGO Technic?
In addition to those comments, another option is the Lego WeDo construction set (9580) [1]. Not as many technic parts, but it contains a couple of sensors (tilt/distance), and the USB hub for interfacing with a computer.
You could also just buy a small technic set or two from the toy store (they are all clearly labeled "technic" on the box), but after buying a couple of these, you'll wish you had just bought a single large set for the value for parts.
[1] https://www.amazon.com/Lego-Education-Wedo-Construction-9580...
NOTE: Same caveat that this set uses the power functions 1.0 plug design, and version 2.0 is upcoming and seems incompatible. Maybe they'll make adapters.
When I looked >= 1-2 years ago, the best single set for spare parts I found was the Volvo L350F wheel loader aka. "42030" [1] (each lego set is uniquely identified by a numeric id). It had the most power functions parts I could find, and probably gives you all the beams, wheels, gears, and other parts you need.
You can supplement your collection with specific parts from places like BrickLink [2] or even the lego.com store [3].
NOTE: Be warned that LEGO is changing their Power Functions plug shape. Most current sets are still on Power Functions 1.0, and new sets will eventually become 2.0
[1] https://www.amazon.com/technic-Volvo-L350F-wheel-loader/dp/B...
42043: - contains the pneumatic pump & tubes which are less common pieces - this is the only other large technic set I've bought (and I got it mainly for the pneumatic parts)
42009: - Lots of beam parts, but not many power functions parts included.
"Turns out the border between genius and insanity is a pretty cheery place."
I think most of the people who make these complaints simply haven't shopped for Lego in a while and so are operating on a lot of feeling but not much data. Stroll down the Lego aisle(s) at Target, you'll see plenty of free-form sets and traditional pieces like these entire product lines: https://www.lego.com/en-us/classic?icmp=COUSFRClassic and https://www.lego.com/en-us/creator?icmp=COUSFRCreator
Check out the architecture series: https://www.lego.com/en-us/architecture
They use mostly basic shapes, and not many colors, but I think have found a nice balance between representation & abstraction for the buildings they model.
Another thing going on is, I think their model designers have gotten a lot more skilled at using pieces in novel ways in their models. They've gotten better at representing details, so more details show up.
But yes, that Creator line is great. I think the 3-in-1 sets especially are very good. My 3-4 yo son loves those. e.g., https://shop.lego.com/en-AU/Vacation-Getaways-31052
Especially when the 3 options are quite diverse; in this case a campervan, a house and a boat. The campervan is particularly clever.
Of course, a just-pieces set of Lego technic would be amazing :-(
They turned things around again in the late 2000s, and in some cases, have gone a bit too far in the other direction, in my opinion. Some sets are overwhelmed with tiny 1x1, 2x1, etc pieces where larger ones (though still from the basic brick set) would be stronger structurally, and wouldn't inflate the piece count as much.
If you want to complain about the current direction of lego, at least pick something that's still going on, like lego's increasing commitment to IPs. These used to be all licensed (Star Wars) but now there are a lot of sets that are on lego-owned IPs like Bionicle.
What there is is much less emphasis on traditional lego lines like "city". There is, if anything MORE availability of basic pieces at different prices. Other than size, why would you need lots of basic sets? The point is that they are basic.
Also, inflation adjusted, bulk purchase of lego basic pieces is historically very low right now, because it mostly seems to track the price of raw materials (mainly oil). I'm not 100% sure of this but I read someone making this case with some analysis on one of the lego collector boards.
Anyway, if you like plain, generic lego, this is probably the absolute best time to be into lego: extremely cheap basic lego in the constructor sets, very reasonable priced SPECIFIC lego in the bulk orders, ability to export from lego cad, the best range of technic parts and computer integration of all time...
lego is in much better shape than it was in the dark days of 2001.

Personally, if I have a big pile of mostly plain bricks, I tend to make a few generic things like a stick figure and a car and a rocketship and then run out of ideas. But give me a piece with a weird angle, or a bar sticking out of it, or a weirdly-shaped socket, or an engraved texture, and I start thinking, "What else could this be? What could I attach to this and how?"
Online Lego galleries (and official sets!) are full of designs that use apparently single-purpose pieces--handheld items for minifigs like weapons, tools, food, and flowers; larger components like doors, radar dishes, and wheel wells; even minifig limbs that were never even designed to be popped off of the torso or pelvis piece--to build weird new joint assemblies or imply small details or represent all sorts of objects. Limitations foster creativity.
Of all the toys that I had as a child, Legos had by far the biggest impact. When I was in college, my mother gave away my "big box of legos" to my cousins. I was, and still am to some degree, devastated. I'm buying legos for my daughter now and its going to be a long time before I can afford to replace what was lost. I still harass my mother about it from time to time (and it's been decades).
Side note: Buying new legos for my daughter, I've come to realize just how much my parents spent on toys for me (and my sister). Even given the fact that the price of legos has increased less (per brick) than inflation, they're expensive. I have dreams of coming upon a great lego stash at a garage sale, so I can jumpstart my daughter's collection and creative "scope". :)
You can buy Lego by the kg or pound from Ebay. Depending how much cleaning and sorting you're prepared to do you can get some bargains.
I have a kid, now, and I definitely look forward to getting to play... or watch someone play... with Erector sets and Lego and all those toys.
edit: Thinking about it some more, Lego is Minecraft, and Erector/Meccano is Kerbal Space Program.
I actually have fondest memories for Meccano - possibly as it was the one I played when I was older. Did used to get upset at my dad "borrowing" bits to help make repairs to cars, greenhouses etc.
What really hooked me was that they were so well suited for electrical components. Adding gears to the axle and making it turn on its own.
I had Erector set (actually "Meccano"), but preferred LEGO/Technic because they just snapped together, you didn't have to spend time screwing a bunch of tiny nuts and bolts together. The feedback loop was shorter.
I also had some other construction toys like Capsela. I don't think I had Tinker Toys, but they seem much more simplistic.
By middle school Technic were the only LEGO sets I was interested in (unfortunately Mindstorms came later, but I had one of it's predecessors, Technic Control Center).
I wrote a blogpost about it and the positive effect on my career:
http://joseoncode.com/2012/02/01/capsela-the-game-that-chang...
Original post in hn:
I don't know that LEGO really pushed out TinkerToys though.
He's right that LEGO is rather inflexible, as far as building structures and mechanisms. You need to mix in non-LEGO materials to build simple machines.
Which would be somewhat amazing, given Mindstorm's pedigree.
- Co-invented Logo Programming language
- Authored "Mindstorms" [1]
- Collaborated with Lego to produce (Logo-programmable) Lego Mindstorms.
- Was made co-director of the MIT AI Lab by...... Marvin Minsky
[1] https://en.wikipedia.org/wiki/Seymour_Papert
[2] https://www.amazon.com/Mindstorms-Children-Computers-Powerfu...
I'm not sure I agree with Minsky, but I have definitely noticed that the Legos of today are very different to the ones I grew up with. Today there is a far, far greater variety of pieces available.
This is definitely a very mixed blessing. On one hand, it does offer a skilled builder many more options, and certainly allows the creation of things that look much better than what could have been created with Legos of thirty years ago. However it also means that finding the right piece takes far more time, which I remember as being the least fun aspect of Legos.
Then there's also the fact that reduced constraints are often not beneficial to the creative process. As a kid, certainly I would have always liked to have had more Legos, but as an adult I realize that an unlimited amount (or, perhaps more importantly, variety) of Legos would probably not have been for the best.
My kid has always enjoyed making shapes in 3D, but not so much the machines part. For 3D manipulation and creativity, she's spent more creative time with Magformers and the magnetic Y-ball and X-ball toys you can find at museum shops, than with Legos.
Erector, on the other hand, was prohibitively expensive which made it hard to have a meaningful enough collection to build what you wanted.
The things you made were a lot more abstract, but people have even made computers using Tinkertoys: http://www.retrothing.com/2006/12/the_tinkertoy_c.html (which doesn't excuse the fact that Minsky was flat-out wrong there)
Minsky's not the only person who has come to that conclusion. Tinkertoys were a good match for young boys' sometimes clumsy hands and, for the older more patient boy, Erector sets were a perfect way to spend a solitary rainy day.
Some chemistry professors, students and engineers still work with Tinkertoy-like tools every day.
Marvin Minsky says LEGO isn't ideal, because you can't build triangles, no pulleys so .. no machines.
there was value to the building experience, the sense of accomplishment, the spatial reading
Toys like this are always so much more memorable--and meaningful.I made a list of gifts that help people build, hack, create, explore etc [1], would love feedback from HN.
The generic pieces were the way to go.
Then, after what seemed like about a year, he started playing with them again. He showed me his long, snake-like sumbaraine with parts of dragon bits here and there which he'd found somewhere in that bin. It was awesome. It was unscripted and creative. It came from his mind, not some 30-paged instruction booklet.
I was more excited to see that kind of creativity than I was the original dragon (which I was made to assemble eons ago). I recently felt a bit jaded about Legos. But my son brought me back.
That was one of the points of this article—people see their themed lines, or their Friends line, and say "why can't it just be like when I was a kid?"—when what Lego said was "why can't we do both, and more?"
It's more likely the reality is the more specialized blocks come and go, and you only remember the more useful ones that survive the generations. There were junk pieces back then too.
It's kinda like saying "all music nowadays is trash, not like the old days". Sturgeon's law applies: 90% of everything is trash, and you only remember the best parts of the past.
When I was a child, the sets I received usually had some sort of theme, even if it wasn't a branded theme. Pirates, space, race cars, whatever. Also, as other articles have pointed out, the majority of the specialized-looking pieces in modern, branded models, are actually creative re-uses of pre-existing pieces. Re-contextualization.
One thing I remember distinctly is that my sets always came with two sets of instructions - one would build the model featured on the box, the other would use a subset of the same parts to build something related but different. Personally, I would usually build the intended model, play with it a bit, then disassemble it for the alternate model. Eventually that would get disassembled as well, added to the big box of unsorted Lego, and would be fodder for modeling some other random idea.
That said, I think I did more experimentation with the Technic line of Lego, which is more like a plastic erector set, than I did with the regular bricks. At least, I remember more of the experimentation with those, probably because it was at a later point in my childhood.
But then roughly once a year I would break down everything I'd built and sort every piece. Then I'd rebuild all the original models.
Funnily I have trouble swallowing medication, but I once put a flat 1x4 piece in my mouth for storage, but accidentally swallowed it. After that I'd always be bummed out when building my fire truck because it would be missing a piece. Back then in the 80's you couldn't get replacement pieces (at least where I lived).
But you could still make your bat mobile engine something else, if you let your imagination run wild during a building process.
Also, I've noticed that my kids (<8yo) both get new Lego, build following the instructions, then within minutes they will be moving pieces around to better suit their style. Or completely destroying it and making something they want to build instead.
Your opinion is common, but it reflects a waning creativity of a person growing older, not a major change in LEGO
My own family experience is reflective: my daughter enjoyed building Lego sets (and got quite good at it) but didn't really engage with playing with them until the Friends sets came out. With Friends she can spend hours creating a huge narrative about their adventures. Now you can't find a coffee table in our house that doesn't have a couple Lego sets on it. And when other girls come over to play, they're drawn like magnets straight to the Legos.
http://lego.wikia.com/wiki/TECHNIC_Figure, http://lego.wikia.com/wiki/8714_The_LEGO_TECHNIC_guys
I'm a bit disappointed they didn't use the same design (or a similar one) for the new figures - there was a lot to be said for the full posability of the Technic figures.
Also, the legs had holes in the side, allowing you to mount bricks either on their feet, or to the side of their legs. This allowed for building reasonably convincing exo-suits.

I am somewhat surprised the chinese haven't started making counterfeit smart bricks with the same capability.

While I've seen the trend of more kids just following the instructions (vs free-building from their imagination), the pieces still provide a lot of opportunity for creativity.
Even better, Lego released their free Lego Digital Designer (LDD) software, which is a CAD-like program where you can build in 3d using the entire catalog of Lego pieces. It opens up many more creative possibilities.
For example, using LDD, I was able to design my own take on the A-Team van.
https://ideas.lego.com/projects/160590
On the Lego Ideas website, customers can submit designs, and the Lego company will consider making them into official sets... Yet another way to stimulate creativity.
Bear in mind that I was doing all of this when I was 10. Clearly this was not normal play amongst my peers, and I would not expect Lego to provoke this sort of thing in most people. However, it was for me a valuable tool in building a worldview which I still strive for today.
My point in mentioning all this is that the great virtue of Lego is that it can be used for pretty much anything. Even if you get a set which is intended for "conflict play," it can be repurposed by the recipient to match whatever it is they're most interested in. (It's sort of like an inverse of the short story The Toys of Peace[2] in that regard.)

Technics is brilliant, even if my enjoyment with it is currently limited to following the instructions. I hope that it'll teach my kids a lot about engineering. The gear boxes in the big sets for example are genius.
Apparently, the visual programming environment was just a thin wrapper on top of C, and people quickly came out with simple IDEs that let you program the brick in C.
I tried to program a musical sequence, and was mystified when programs involving simple decimals didn't work. I didn't understand at the time, but the Yellow Brick didn't have any floating-point support! I eventually just faked it with a good-enough approximation of using integers to emulate fixed-point arithmetic.
Legos are amazing and are definitely the focal point of my kids (age 5 and 9) creative play.
Not only does the difference not matter, I'm not sure I believe that there is a difference. When kids play, they're acting out variations on stories they've encountered. I don't see a real difference between performing scenes from a video game and performing scenes from a book, movie, TV show, or real life.

I saw another mention of a raspberry pi driving Technic on here. Has any tried this?
If you get the Lego USB hub part (9581), you can attach Power Functions v1.0 components to your raspberry pi via the hub. Works right away. The USB hub has two channels, so you can use it to control 2 motors, 1 motor + 1 sensor, or 2 sensors.
The LEGO extension to Scratch has controls like:
- Set Motor (A or B or both) to speed 0-100
- Turn Motor (A or B or both) on for x seconds
- Stop Motor ...
- Reverse Motor Direction
- Read tilt/distance sensor value
I've also worked out the IR codes (with the help of others' work) so if you hookup an infrared led to your pi and install LIRC you can imitate the Power Functions remote controls.
The power functions pieces have special bricks which embed electrical endpoints which click together when the bricks are connected. The system is basically 4 wires - 2 which propagate the power rails to downstream pieces, and 2 more wires which are for PWM controlling of motor spin rate.
I would love it if they added more electronic components to this set (eg. timers, sounds, more sensors, etc). If you like to tinker, you can cut apart these wires and hook up the control wires to an raspberrypi-controlled circuit.
There's probably even more circuits possible with Mindstorms components, but I'm not familiar enough w/ Mindstorms to comment.
After a few times you consider crawling across the floor probing the floor before you as if you were Rambo in a minefield.
(I know you can still buy the basic box full of bricks, but these are sometimes hard to find)
One thing I've always really wanted was a modular castle line, akin to the modular town building series, e.g. https://shop.lego.com/en-US/Pet-Shop-10218
