3D Modeling with Blender

We have made a few posts showing off our 3D printers and some of the classes on 3D printing that we have done here at Digilent. Garrett Mace from macetech.com showed us some of the basics on how to use various 3D modeling software like AutoDesk Inventor, Autodesk 123D Design, OpenSCAD, MeshMixer, and SketchUp. Today, I’m going to introduce some of the basic modeling tools available in the free but robust Blender.

Nexys vs. Basys

At Washington State University, the electrical engineering department uses Digilent FPGAs in several classes. Students are allowed to pick from a variety of our FPGAs. The main choice is between the Nexys or Basys lines of FPGAs. As a student, I hear a lot of confusion from students about the differences between the two series of boards. I figured that students can’t be the only ones who have questions about the difference, so I decided to write a quick summary of the differences. I’ll be using the Nexsys 4 and the soon-to-be newest member of the Basys series as an example. I’ve compiled two lists to highlight the differences between the two.

WF32 Pin Diagram

I’m a big fan of the chipKIT WF32. It’s a powerful little board with a WiFi card and SD card reader built in, but there’s a lot more to this board than meets the eye. There are a ton of communication lines, external interrupts, output compare pins, and more hidden in all those GPIO pins, but how do you tell what is what? That’s where the WF32 pin diagram comes in. I’ve compiled, color coded, and listed what each pin is capable of.

Electric Dune Buggy

I’m an intern at Digilent working on converting a dune buggy to electric power. Once the buggy is complete, the operator will have the options to use either remote control or autonomous operation and will exemplify the functionality of Digilent products. The overall goal is to create something fun yet safe that will encourage innovators to go out and build something awesome.

Fritzing and Digilent

At Digilent, we use Fritzing to present educational concepts. A lot of our Learn projects feature Fritzing. A number of our parts (with more being added regularly) are in Fritzing Projects (search for Digilent) and in the user-created parts repository. From designing circuits to demonstrating new concepts, we use Fritzing for showing people what we’re working on. We also use some Fritzing graphics in our inventories for our Learn projects. (The one shown below is from a project about debouncing circuits with libraries.)
