DIYmakerspaceDo-It-Yourself Engineering is a unique 24-lecture video learning experience offered by The Great Courses.  In this course, Professor Ressler guides you through 17 challenging hands-on projects, designed to enhance your understanding of basic math, science, and engineering concepts.

This web page provides the following supplemental DIY Engineering resources, organized by project number:

  • Sketchup 3D computer models (.skp format) for all projects
  • 3D computer models for 3D-printing (.dae format)  for Projects 12 and 13
  • Full-size layouts for laser-cutting (.svg and .eps formats) for Projects 14 and 15
  • Full-size layout drawings and cutting patterns (.pdf format) for Projects 1, 2, 5-9, 11-13, and 16
  • Excel spreadsheets (.xlsx format) used to perform advanced computations for Projects 5, 9, and 12

PLEASE NOTE: These resources are provided solely for the use of Great Courses customers who have purchased DIY Engineering.  These resources are intended as a supplement to the course, not as a substitute for it. To understand how the 17 DIY projects are designed, built, and tested, you’ll need to view the course! And by purchasing DIY Engineering, you will also be supporting the development of future courses.
