Blender is a power tool for rendering 3D visualizations used in creating animations, special effects, interactive 3D computer applications, video games and models for 3D printing. Historically the interface for using Blender has had the repuation of being difficult to learn to use, but recent development on Blender has been focused on improving the user interface.
This class will be an introduction to the Blender user interface (UI) including how to use the keyboard and mouse effeciently. The class will cover how to model a fairly simple object including the use of a few handy modifiers included in Blender. This class will not cover texturing, rigging, rendering, animation or the game engine, but if there is interest in these topics you should look for a future class on these advanced topics. At the end of the class you should have a firm basis to make more informed searches of how to do what you want with Blender.
Tiny85: a simple, cheap alternative to dedicating an Arduino to a long-term project
Atmel offers several processor chips in the same family as the Arduino’s ATMega328P that are often perfect for a simple permanent controller. This class introduces you to the ATTiny85, with mention of some others. You’ll leave with an ’85 running a simple blinkie with code you wrote, you ported to Tiny85, and you burned into the ’85 along with a mini shield to use an Arduino as a programmer for the ’85 and many other Atmel chips.
The class is open to Arduino users with at least basic programming skills. (You’ll need to be able to modify the Blink sketch.) You’ll need to bring a working Arduino (or clone), a laptop with the Arduino 1.0.4 development environment, and a breadboard. We’ll supply a Tiny85.
Workshop 88 is offering our introduction to the Arduino platform at our makerspace in Glen Ellyn.
This class is for anyone who wants to learn how to get started with the arduino microcontroller, regardless of experience with programming or electronics.
Class attendees will learn how to configure their arduino programming environment, how to design simple circuits for interfacing with the arduino and how to write simple programs to control the arduino. What is Arduino, you ask? From their home page:
Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It’s intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments.
If you need to get an arduino, please see the Workshop 88 Arduino Store. Sales from that store are fulfilled by amazon.com, and help support Workshop 88. Alternatively, you can order Arduino systems from several places, including Adafruit and Sparkfun. Both companies have lots of tutorials and howtos to get you started with Arduinos. If you’re looking for a local source to get Arduinos, try Trossen Robotics.
What you’ll get from this class: If you choose the registration + materials option, we will have an arduino and assortment of electronics components for you to take home after the class. (The Workshop 88 Arduino Store is by far a cheaper route to get supplies.)
In this class you will learn how to start programming in the Arduino environment including interacting with the inputs and outputs of the Arduino.You should bring: a laptop with the Arduino environment downloaded and installed.

Two of the questions we often get at Workshop 88 are: “How many people show up to your public meeetings?” and “What usually goes on at your public meetings?”
If you’ve been wondering the same things about Workshop 88, take a look at what was going on during our last meeting:
If you’ve never been to Workshop 88 before, the video gives a sense of how the makerspace is laid out. We have four areas from front to back: meeting room, wood/metal shop, electronics/rapid prototype lab, and multimedia room. All the rooms get a lot of use; it just happened that when the video was shot there were not many people in the back rooms.
Workshop 88 member Jim Williams shared these breadboard photos for our “What’s on Your Breadboard series
This board had a electret microphone with preamp on it, for use in an arduino class that we ran. As you can see, he eventually put the circuit onto a PCB.

The second breadboard shows that sometimes a breadboard is just a convenient way to connect one sensor to an arduino. In this case, it was an ultrasonic rangefinder that Jim wanted to test with the arduino. He reported that it worked well.
