Lego Technic Builder’s Guide

The Unofficial LEGO Technic Builder’s Guide by Pawet “Sariel” Kmiec (Second Edition) tells you how to build machines, models, robots, etc. that will work.

screen-shot-2016-11-25-at-5-46-11-pmYou need to construct these things in a way that ensures they won’t easily fall apart, and that requires a certain amount of engineering. There are some fairly expensive and specialized Lego Technic pieces that you may not have on hand, and this book can help you emulate them. How do you matcha motor or servo to a specific task? You need to know some stuff to make that decision sensibly. How do you make a transmission? Or an independent suspension?

And, very importantly, how do you manage the backlash that is “the gaps between mating components.” That seems important.

From the publisher:

This thoroughly updated second edition of the best-selling Unofficial LEGO Technic Builder’s Guide is filled with tips for building strong yet elegant machines and mechanisms with the LEGO Technic system. World-renowned builder Pawe? “Sariel” Kmiec covers the foundations of LEGO Technic building, from the concepts that underlie simple machines, like gears and linkages, to advanced mechanics, like differentials and steering systems. This edition adds 13 new building instructions and 4 completely new chapters on wheels, the RC system, planetary gearing, and 3D printing.

screen-shot-2016-11-25-at-5-45-47-pmYou’ll get a hands-on introduction to fundamental mechanical concepts like torque, friction, and traction, as well as basic engineering principles like weight distribution, efficiency, and power transmission—all with the help of ­Technic pieces. You’ll even learn how Sariel builds his amazing tanks, trucks, and cars to scale.

This beautifully illustrated, full-color book will inspire you with ideas for building amazing machines like tanks with suspended treads, supercars, cranes, bulldozers, and much more. What better way to learn engineering principles than to experience them hands-on with LEGO Technic?

New in this edition: 13 new building instructions, 13 updated chapters, and 4 brand-new chapters!

We’re only starting to mess around with techincs but there is a lot of hope for it. People are starting to combine arduino and traditional robotics, Lego and robotics, and arduino and LEGO Technic. Pretty soon, someone will be combining Arduino controllers, Raspberry Pi computers, LEGO technics, and the Cyberdyne Systems hardware, and we’ll all be history…

But in the meantime, The Unofficial LEGO Technic Builder’s Guide will be our guide for the immediate future.

The Cult of Lego

IMG_0052The Cult of Lego is a thing … a cult … a past time, a cultural phenomenon. But it is also a book called, as you might guess, The Cult of LEGO.

The book is written by John Baichtal, of Make Magazine and Wired GeekDad blog and Joe Meno, the founder of Brick Journal. The publishers describe the book thusly: “The Cult of LEGO® takes you on a thrilling illustrated tour of the LEGO community and its creations. You’ll meet LEGO fans from all walks of life, like professional artist Nathan Sawaya, brick filmmaker David Pagano, the enigmatic Ego Leonard, and the many devoted AFOLs (adult fans of LEGO) who spend countless hours building their masterpieces.” And that is pretty accurate.

IMG_0057Lego has an interesting history. The company Lego Group is Danish and was founded in 1932, an early on made a variety of toys. “LEGO” comes from Leg godt” which is danish for “Play Well.”

The company survived, perhaps even thrived ruing, Nazi occupation of Denmark. They company started making injection molded toys after WW II, and began production of the Lego blocks we are familiar with today in 1947.

IMG_0058We learn from The Cult of LEGO that at present there are about 62 LEGO bricks or parts for every person on the planet earth, though obviously they are rather unevenly distributed. In total there are 2,400 different “elements” (kinds of bricks and such) that have been produced in 53 different colors. I’m not sure if that includes Duplo or not.

Also, there are about 200,000 Youtube Videos that address LEGO. However, if you search for “lego” on Youtube there are over 13 million entries. That exceeds the 9.5 million entries one finds in searching the word “Evolution.” (Presumably both search terms find many entries that are not specifically about the building bricks or Darwin’s famous theory.)

IMG_0061The book is totally pro-LEGO, almost jingoistically so, but if you are a LEGO cultist, you will not mind. The Cult of LEGO covers all aspects of LEGO cultism, and provides a wide ranging survey of LEGO life, with these chapters:

Chapter 1: The History of LEGO
Chapter 2: Building Again
Chapter 3: Minifig Mania
Chapter 4: (Re)creating Icons
Chapter 5: Building from Imagination
Chapter 6: LEGO Art
Chapter 7: Telling Stories
Chapter 8: Micro/Macro
Chapter 9: Digital Brickage
Chapter 10: LEGO Robotics: Building Smart Models
Chapter 11: Gatherings
Chapter 12: Serious LEGO

I’ve covered a lot of LEGO related books on this blog. This book is different from all the others in that it is not a “how to” book. Rather, it is a guide to the bigger picture of LEGO world, a coffee table book to place right next to your latest LEGO creation or perhaps, on the coffee table you’ve made out of LEGOs. In your room made of LEGOs, in your house made of LEGOs, where you live along side various LEGO people you have made.

No other book I’ve seen says “I welcome our new LEGO overlords” better than this one.

Lego Adventure

The LEGO Adventure Book, Vol. 1: Cars, Castles, Dinosaurs & More! by Megan Rothrock is primarily for people who have been messing around with LEG for, say, less than 10 years or so, especially those who are new at it and seek both inspiration and guidance in such daunting tasks as making a scale two engine turboprop airplane or an entire Lego town.

The book guides the reader step by step through 25 exemplar models, each of which is fairly elaborate, and demonstrated with more basic information close to 200 other models to illustrate variation. Despite the name of the book and a fairly high degree of silliness in some parts (the Lego figures have a few things to say) the 200 page volume actually has a lot of information in it. The copy I have is hard cover and has thick glossy paper which means that when I open it to a certain page it stays open at that page. That may seem like a small thing but for a guide book for something you need both hands to do, that is a key feature.

To give you an idea of what the book covers, I’ve copied the table of contents:

  • Chapter 1: Building the Idea Lab
  • Chapter 2: A LEGO Town
  • Chapter 3: Hot Rods and Cool Rides
  • Chapter 4: From Below!
  • Chapter 5: The Sky’s the Limit
  • Chapter 6: The Turtle Factory
  • Chapter 7: Starfighters
  • Chapter 8: Mighty Mecha
  • Chapter 9: Medieval Village
  • Chapter 10: Triassic Park
  • Chapter 11: Making New Friends
  • Chapter 12: Full Steam Ahead
  • Chapter 13: Steampunk
  • Chapter 14: A LEGO Legend

The author, Megan Rothrock, was a set designer for Lego, and her displays have been see at ComicCon and other places. Rumors that she is a member of The Cult of LEGO are unfounded. Well, probably not.

Be a Lego Stud: The Unofficial Lego Builder's Guide (new edition)

The other day I reviewed a guide to using the very high end Lego Technic system. Here, I’ve got a book that addresses the needs of those at the other end of the Lego Spectrum: The Unofficial LEGO Builder’s Guide

By “other end of the spectrum” I do not mean unsophisticated or easy, I simply mean no electrical gizmos and not too many gears and things. For example, you might use this guide to build a very realistic scale model of the Space Shuttle or a cool Train Station with People waiting for the Train model. Or, perhaps, a house with a chimney. But a really cool one. Continue reading Be a Lego Stud: The Unofficial Lego Builder's Guide (new edition)

Tinkering with Lego Technic

Lego Technic is a Lego based technology that includes a combination of totally new kinds of Lego pieces and fancy technology that lets you build some amazing things. You can get kits that range in cost and sophistication from the LEGO 8514 Technic Power Roboriders a sort of motorcycle for robots that costs tens of dollars to a Motorized Bulldozer that will set you back nearly $700. Actually, I think there may be Techno kits that cost way over $1000.

The modified Lego pieces include the techno “brick” which comes in many forms that have holes in them through which specially shaped parts can be inserted, to have an armature that does not rotate, an axel, or some sort of pivot. Some of the tecno Lego parts seem to converge on Erector Set pieces, but without the annoying little nuts and bolts. Then there are gears and pullies and all that stuff, and on top of that, electronic doohinkeys. You can get electric motors, you can get a differential, and clutches. You can get lights. There is even a pneumatic system. Actually, there’s two different ones, a legacy system and an updated system.

With enough parts and some good design, you might actually be able to design a Lego Technic machine that does something useful. Like one that brings you a beer or scares away solicitors at the front door.

I’ve got this book that seems to be the book to have if you are going to start messing around with this Robotic Technology: The Unofficial LEGO Technic Builder’s Guide. If you know someone who is planning to play around, er, I mean engage in DIY hobbyist activities, with this form of Lego, do them a favor and get them this book so they can mix and match and design their own stuff rather than buying those expensive kits. Some details from the publisher:

The Unofficial LEGO Technic Builder’s Guide is filled with building tips for creating strong yet elegant machines and mechanisms with the Technic system. Author Pawel “Sairel” Kmiec will teach you the foundations of LEGO Technic building, from simple machines to advanced mechanics, even explaining how to create realistic to-scale models. Sariel, a world-renowned LEGO Technic expert, offers unique insight into mechanical principles like torque, power translation, and gear ratios, all using Technic bricks. You’ll learn how to:

  • Create sturdy connections that can withstand serious stress
  • Re-create specialized LEGO pieces like casings and u-joints, and build solutions like Schmidt and Oldham couplings, when no standard piece will do
  • Build custom differentials, suspensions, transmissions, and steering systems
  • Pick the right motor for the job—and transform its properties to suit your needs
  • Combine studfull and studless building styles for a stunning look
  • Create remote-controlled vehicles, lighting systems, motorized compressors, and pneumatic engines

The The Unofficial LEGO Technic Builder’s Guide, being unofficial, is not a catalog or sales pitch, but rather, a very well organized and clear guide to getting the most out of your new toy, er, hobby. Start at the beginning, work towards the end, and you’ll be an expert modeler and maker of things Lego-Technic. Nothing that flies, though. But a lot of stuff that drives.

Taking Lego to the Max

Huxley’s Aunt and Uncle have given him, as Christmas and Birthday presents, various kits to make Imaginarium style train setups. Imaginarium is like Brio and Thomas the Tank Engine, but generally available as a Toys R Us Brand. He has enough cool bits and pieces to make a kind of double figure eight layout, but the ends can’t ever be closed into a continuous loop because we don’t have enough pieces of track. Or maybe we do. We keep trying different configurations but it never works. It also may be the case that while Huxley, Amanda and I make great Train Engineers once the tracks are set up, we make lousy Civil Engineers when laying them out. We need to hire a consultant.

This is the same problem with Lego. You see all these amazing Lego things people put together … especially if you go to Lego Land at the Mall of America across town from here. But, when you start putting this stuff together, at first, it is hard to do because everything really has to be just right to make it work, especially if electronic motors and gears and stuff are involved.

You can learn to make great Lego thingies through extensive trial and error, or you can hire a Lego consultant, or you can just get these books by Yoshihito Isogawa. I’ve got two of them (I think there may be three or four in total): The LEGO Technic Idea Book: Simple Machines and The LEGO Technic Idea Book: Wheeled Wonders.

These are very smart books. There are no words in them, just a few on the cover and in the very beginning. It is all pictures, some of which I’ve pasted here to give you an idea.

The different types of blocks in a given picture are always different colors so you can easily see what is what. There are icons that tell you what kind of assembly you are looking at, and what principle is being illustrated, such as “turning” or “a door” or “putting something in or on something” and that sort of thing. As far as I can tell, it is pretty much one assembly per layout (two pages facing each other) with several angles and other helpful illustrations on each layout. The idea is that you can build the thing that is depicted by looking at what the illustrations (mainly photographs) show, and when you do so, you learn something about how Lego assemblies are made.

The books are divided into parts and chapters. So for the Wheeled Wonders book, Part 1 has Motorcars, Cars that Spin Something, Cars that Move something … Part 2 has Differential Gears, Steering, Suspension … Part 3 has Combining Vehicles with Different Bases, Reversing After bumping a Wall, Using Pullback and Windup Springs … Part 4 has Transmission and a special section called Cool Cars. Clearly, you can see the pattern: Increasing complexity as you move through the book, with later chapters building on earlier ones.

The Simple Machines book has too many chapters for me to name them all, but it starts wiht basics (Gears, Shafts, Turntable, Angled Gears, Womr Drives, etc.) then covers power and motion (Chains and Treads, Rubber Bands, Rack and Pinion, etc.), then motors, more complicated chassis, doors, pulley systems, and eventually, amazingly, provided diagrams with instructions to make a couple of musical instruments.

The author, Yoshihito Isogawa, of Tokyo, is a Lego master and has written a whole bunch of books like this. Imagine having that job!

I think the idea here is that you build from the examples, mainly working from simple to complex, until you find yourself anticipating what the instructions would say, and eventually getting to the point where you don’t need them at all. Thereafter you’d probably find these volumes handy as references in your Ultimate. Geek. Library.
