I hope that by now you’ve gained a good understanding of the LEGO Technic system and how to build your own models. If you’re looking for more avenues to explore, I can recommend other interesting pieces no longer in production, such as elements of the radio control system (8366 set) and the barcode IR system (8479 set), an entire discontinued building system (8369 set), and some very rare modern pieces, like the Power Functions solar panel and energy display (9688 set).

And of course the LEGO Group also keeps introducing new parts, making new solutions possible or simplifying existing designs. Even if you’re a fan of the old school “all studfull” style of building, it pays to keep track of these novelties. For more inspiration, there is the worldwide community of LEGO builders who keep inventing and perfecting designs and sharing their ideas freely for others to try.

Having built well over 120 MOCs in the last few years,

I can say that the trial and error of building your own constructions is not the bad part of building—it’s actually the most enjoyable part. Getting to play with your finished working construction is a nice touch, but the real pleasure comes from successfully tackling problems, big and small, which always crop up when you choose to create rather than to build from instructions. With enough trial and error, the only real limit to what you can build is your own imagination.

It is my wish that this book helps you to experience plenty of that pleasure as you play with LEGO pieces.
