You’ll find hundreds of clever, buildable mechanisms, each one demonstrating a key building technique or mechanical principle. You’ll learn to build sliding doors, grasping claws, rack-and-pinion mechanisms, and ball-shooting devices of every sort! Each model includes a list of required parts and colorful photographs that guide you through the build without the need for step-by-step instructions. As you build, you’ll explore the principles of simple machines, gear systems, power translation, and more.","forthcoming":false,"isbn13":"9781593276881","publication_date":"20151001","publisher":"No Starch Press","slug":"the-lego-power-functions-idea-book-volume-1","subtitle":"Machines and Mechanisms","title":"The LEGO Power Functions Idea Book, Volume 1"},"discovery":{"categories":{"all":[{"bisac_code":"JNF061020","confidence_band":"medium","label":"Robots & Robotics","score":0.7699,"source":"bisac_hint_model"},{"bisac_code":"JNF051120","confidence_band":"medium","label":"How Things Work","score":0.768,"source":"bisac_hint_model"},{"bisac_code":"JNF051130","confidence_band":"medium","label":"Machines & Tools","score":0.7605,"source":"bisac_hint_model"}],"hint":[{"bisac_code":"JNF061020","confidence_band":"medium","label":"Robots & Robotics","score":0.7699,"source":"bisac_hint_model"},{"bisac_code":"JNF051120","confidence_band":"medium","label":"How Things Work","score":0.768,"source":"bisac_hint_model"},{"bisac_code":"JNF051130","confidence_band":"medium","label":"Machines & Tools","score":0.7605,"source":"bisac_hint_model"}],"publisher":[{"bisac_code":"CRA020000","confidence_band":"high","label":"Model Building","score":1,"source":"onix_publisher_code"},{"bisac_code":"CRA043000","confidence_band":"high","label":"Kids' Crafts","score":1,"source":"onix_publisher_code"},{"bisac_code":"TEC009070","confidence_band":"high","label":"Mechanical Engineering","score":1,"source":"onix_publisher_code"}]},"genres":[{"label":"Robots & Robotics","score":0.7699,"slug":"robots-robotics"},{"label":"How Things Work","score":0.768,"slug":"how-things-work"},{"label":"Machines & Tools","score":0.7605,"slug":"machines-tools"}],"reader_fit":["Good for readers interested in building LEGO Technic mechanisms","Readers exploring gears and simple-machine principles"],"related_lists":[],"series":null,"similar_books":[{"authors":["Jessica Farrell","Hannah Dolan"],"book_id":"9780744099027","cover_image_url":"https://img.bookfrontier.com/9780744099027.jpg?v=b9f40ff86dcc7168","score":0.77,"title":"How to Build LEGO Robots","url":"https://bookfrontier.com/books/9780744099027"},{"authors":["Jeff Friesen"],"book_id":"9781718502505","cover_image_url":"https://img.bookfrontier.com/9781718502505.jpg?v=776762fddf65fa93","score":0.759,"title":"The LEGO® Engineer","url":"https://bookfrontier.com/books/9781718502505"},{"authors":["Holger Matthes"],"book_id":"9781593278199","cover_image_url":"https://img.bookfrontier.com/9781593278199.jpg?v=2a235b862701fc09","score":0.753,"title":"The LEGO Trains Book","url":"https://bookfrontier.com/books/9781593278199"},{"authors":["Shari Last","Julia March"],"book_id":"9780744099157","cover_image_url":"https://img.bookfrontier.com/9780744099157.jpg?v=ef1d3e006cba5287","score":0.7356,"title":"LEGO Minecraft Ideas","url":"https://bookfrontier.com/books/9780744099157"},{"authors":["Colleen AF Venable"],"book_id":"9781250152169","cover_image_url":"https://img.bookfrontier.com/9781250152169.jpg?v=5f4bfca644264832","score":0.7093,"title":"Maker Comics: Build a Robot!","url":"https://bookfrontier.com/books/9781250152169"},{"authors":["Charles Pritchett"],"book_id":"9781718500488","cover_image_url":"https://img.bookfrontier.com/9781718500488.jpg?v=b967d480e3d5680e","score":0.705,"title":"LEGO Train Projects","url":"https://bookfrontier.com/books/9781718500488"},{"authors":["Jenny Jacoby"],"book_id":"9781631585852","cover_image_url":"https://img.bookfrontier.com/9781631585852.jpg?v=69528344567d5cac","score":0.6987,"title":"STEM Starters for Kids Robotics Activity Book","url":"https://bookfrontier.com/books/9781631585852"},{"authors":["Clive Gifford"],"book_id":"9781438050409","cover_image_url":"https://img.bookfrontier.com/9781438050409.jpg?v=f4fe60cd71e2cc19","score":0.695,"title":"A Robot World","url":"https://bookfrontier.com/books/9781438050409"}],"topics":[{"evidence_refs":["keyword:books for 11 year old boys"],"label":"Year","score":0.8411,"slug":"year"},{"evidence_refs":["keyword:books for 11 year old boys"],"label":"Boys","score":0.4174,"slug":"boys"},{"evidence_refs":["keyword:gift ideas"],"label":"Ideas","score":0.0281,"slug":"ideas"},{"evidence_refs":["keyword:stem"],"label":"Stem","score":0.0255,"slug":"stem"}],"what_you_get":["Themes: LEGO mechanism building, Gears and power translation, Simple machine principles.","Themes: Year, Boys, Ideas.","Reading lane: Robots & Robotics and How Things Work."]},"llm_signals":{"confidence":0.96,"pacing":"unknown","reader_fit":["Readers interested in building LEGO Technic mechanisms","Readers exploring gears and simple-machine principles"],"themes":["LEGO mechanism building","Gears and power translation","Simple machine principles"],"tropes":[]},"source_presence":{"amazon":true,"book_detail":true,"goodreads":true,"llm_signals":true,"similarity_seed":true},"stats":{"amazon_ratings_count":661,"goodreads_ratings_count":66,"goodreads_reviews_count":2,"quality_score":0.8643}}
