There’s something new for LEGO Technic fans from No Starch Press.
These books from Yoshihito Isogawa are a great guide to all the wonderful ways you can combine LEGO Technic gears and related elements. I’ve always been a little wary of Technic myself. Even though I got an Expert Builder parts pack as a kid, I never did a lot with it. (I was probably too young, since I was only 6 when that set came out in 1977.) I’ve built a number of modern Technic sets, most recently the Lego Technic Crane Truck 8258
, but I’ve only done minimal work with designing my own Technic machinery. Mostly what I’ve done is simple gearing such as my Scrambler amusement park ride, but I always seem to have trouble getting the gears to do quite what I want without either destroying the gears, skipping teeth, or woefully misjudging speed and/or torque.
The first book is The LEGO Technic Idea Book: Simple Machines which shows a myriad of different ways to combine LEGO gears and pulleys to achieve particular gear ratios and directions. If you’ve ever scratched your head wondering how to get a certain speed or torque out of a LEGO motor, your answer is in here. Even the most experienced builders will certainly find something new they can use. For example maybe you know how to get the gear ratio you want, but the mechanism you’re thinking of is too bulky to fit into the model you’re working on. Take a look through this book and there’s a good chance you’ll find a better way to get the same effect in the space that you need to fit it into.
The LEGO Technic Idea Book: Fantastic Contraptions is full of clever ways to combine gears, pulleys, springs, and magnets to create models that move. There are ideas for shooting projectiles, building shock absorbers, and even using magnets to animage LEGO minifig scenes. The only problem is that the magnets shown have been discontinued (due to fears that a child might swallow magnets which would get stuck in their digestive tract and require surgery – for example, the new train sets have a redesigned coupler with a magnet permanently affixed), so that might be frustrating to some people without extensive collections of older parts.
Finally, the The LEGO Technic Idea Book: Wheeled Wonders is full of great ideas for LEGO vehicles. Drivetrains, steering mechanisms, and other vehicular ideas are illustrated in full detail.
The examples in these books are purely pictures. There are no verbal explanations, which you would think would be a problem. But the pictures are reduced to such a level of simplicity that it’s easy to understand the mechanism without any text, and if you build them you could easily understand how they work. There are a lot of tips that show ways of combining gears that I had never thought of, and as I was flipping through it I kept thinking “Oh, that would be good for X” type thoughts. The lack of text would also be helpful for younger kids or people whose primary language is not English (or Japanese, in this case).
I think the one area where this could have been improved would be to show more complex ideas – instead of just showing the simple combinations of parts to achieve a particular kind of connection, show ways to combine these together to create more intricate machines. Some of the examples in the Fantastic Contraptions and Wheeled Wonders books do this to some extent, but I’d prefer to see that taken to a higher level. Also, instead of just showing each model from a variety of angles, I’d like to see step-by-step building instructions or to see some of the simpler modules combined together to create more detailed ones.
One area that isn’t explored very well is motorizing the sets. There are some examples that use motors, but they are largely built using the older 9V motors instead of the current Power Functions parts, and with the Power Functions remote control system, there are a lot of things you could do that aren’t covered by these examples. Hopefully they will come out with a fourth book featuring Power Functions.
All in all though, these are excellent books showing a lot of great ideas for LEGO mechanisms. Even if you’re an experienced builder, there are surely some ideas in here you’ve never seen.
