Mechanix Illustrated was an American printed magazine that was originally published by Fawcett Publications. Its title was founded in 1928 to compete against the older Popular Science and Popular Mechanics. Billed as "The How-To-Do Magazine," Mechanix Illustrated (MI) aimed to guide readers through various projects from home improvements and advice on repairs to "build-your-own (sports car, telescope, helicopter, etc)." It was headquartered in New York City.
