There is a tutorial available for this Sketchup plugin which allows you to find holes or reversed faces in your models. Recently, there was a model designed which failed to print correctly. When using the CADspan plugin, it was discovered that many of the faces were reversed:
The red faces are the ones that needed to be corrected. A few right-clicks later and the model was fixed:We’d love to know your tips and tricks for getting better prints from your own designs. Let us know!
Inspired by Kirk and the Kobayashi Maru, when Jim was faced with the near-impossible task of winding hundreds of turns of wire through a toroid core, he cheated.
By cleanly breaking the core in half and gluing one half to a spindle chucked in an electric drill, the winding became fairly easy. Super gluing the halves together afterward produced a magnetically and physically sound toroid again.
Several folks at the space helped Jim with his experiment, holding wire, counting turns, operating the drill, and of course taking pictures. Many thanks to Ti Leggett for his efforts and skills as the photographer. There are more details in Jim’s project notes, but here’s the video:
We had a great turnout for the electronics 101 class! It was so great to see everyone who came out to learn a bit about the fundamentals of electronics today. Big thanks to Eric, Paul and Bill who all helped out today with the class. Remember to sign up for the Electronics 102 class next week!
