If you thought the LEGO Stop Animation Digital Video Camera that Janet posted about earlier today was interesting, you might want to check out the 3 volume series of LEGO Technic Idea Books from O’Reilly. These books offer 100′s of ideas through photographs with little to no text. Volume 1 is The LEGO Technic Idea Book: Simple Machines. This volume focuses on gears and power transmission. Volume 2 is The LEGO Technic Idea Book: Wheeled Wonders and its main focus is on vehicles that can drive, turn, move things, and go backwards. Volume 3 is The LEGO Technic Idea Book: Fantastic Contraptions and it offers ideas for combining LEGO Technic propellers, motors, weights, magnets, and other parts to make creations that walk. Each book is $19.95 and is currently available for pre-order with availability sometime in October.
