One of my colleagues pointed out a couple of weeks ago that Instructables offers free classes on many “makerspace” related topics, such as laser cutting, mold making, and 3d design.  I’ve used the site for a few DIY projects, but never knew I could dig deeper with these lessons.  I plan to investigate several of these for my own studies, and now I know that I can also refer some of my students to the site, especially if they want to learn more about something I may not have tried yet.  It’s a good resource for DIY’ers, educators, and students.
