I briefly introduced TinkerCAD so that students needing 3D printed parts for their projects might consider using this tool. I recently heard about 3DTin from a colleague, and may offer this as an alternative 3D modeling tool. Like TinkerCAD, it is web-based, and since it uses existing google accounts for logins, is quick to get up and running.
More students have created laser cut prototypes for their projects. This tool will get a lot of use. Because of its ability to print quickly, and to use a variety of materials (wood, acrylic, felt, even metal engraving) it is extremely versatile and immediately gratifying. Students can use the results of their digital work within a class period.
Here are recent photos, and a video of a completed light cube project. This one uses an Arduino Uno and RGB LEDs to produce a color changing effect. More details are available on Flora's blog.
