Pawel "Sariel" Kmiec is a legend in the Lego world. If you have ever seen a video with some amazingly complex machine made of Lego, you probably already know his work. If not, take a look at this awesome video compilation first, then keep reading.

It's truly impressive. Obviously, Pawel is a master of Technic, the advanced mechanic Lego that allows anyone to create practically anything imaginable. His machines are fantastic.

The only problem is that using Technic, like any other advanced Lego builds, requires technical knowledge, actual engineering skills and a lot of design genius. Of course, you can learn the techniques. Once you grasp the basic concepts, you'll be able to start building complex machines too.

Luckily for you — and me — Pawel has published a new 352-page colour book called The Unofficial LEGO Technic Builder's Guide to speed up that learning process. In it he reveals all his secrets, which are many. You can buy it at [Amazon]
