Introduction to Basic Electronics, Electronic Components and Projects. Learning about basic electronics and creating your own projects is a lot easier than you may think.
In this tutorial, we’re going to give you a brief overview of common electronic components and explain what their functions are. You will then learn about schematic diagrams and how they are used to design and build circuits. And finally, you will put this information to use by creating your first basic circuit. Before you get started, make sure your electronic workbench is properly set up. This Machine Prints Portraits with 8,000 Drops of Coffee. We’ve all seen printers use ink, and if you’ve been to a Maker Faire you may have been lucky enough to see a machine printing with chocolate or pancake batter.
RIT Assistant Professor Ted Kinsman decided that he wanted to print with coffee. “For many years I have thought about building a machine that could paint for me,” he says. “Since I always have leftover coffee, I thought it would be a fun medium to play with.” Using an Arduino and an x-y plotter, he’s been able to do just that. He explains, “The machine allows experimentation with drip height, drip size, drip chemistry, spacing of drips, and especially the paper that the drips fall on – all of these affect the image results.” Kinsman takes a portrait, heightens the contrast, and converts to a PGM file. He uses a Mariotte’s siphon so that the depth of the coffee in the reservoir won’t affect the pressure, which in turn could influence the size of the drops. What should we teach students about the future of technology? Will we ever become technology?
It sounds like a science fiction statement, but it’s actually not too far from reality. Humans rely on programmable devices for every aspect of their daily lives. These devices have transformed from stationary, to carried and worn, to physically implantable. There is no end to this progression; innovations keep evolving. With the ongoing focus of technology in education, and the need for schools to keep up with the ever-changing scope of its use in the classroom, it is essential that we provide students with the knowledge of how technology affects, and will affect, society.
In looking at the future and how we interact with programmable devices, students need to understand both the positives and negatives surrounding the use of robotics and artificial intelligence to simplify human tasks. Have I been pwned? Check if your email has been compromised in a data breach.
The File Extension Guide: How to Fix and Batch Rename Your Files. Do you have broken files with missing or messed up file extensions?
If you know the file type, adding the right extension could make those files readable again. And if you have more than a few files with this issue, we have something that could save you a lot of time: batch rename the file extensions. Introduction to File Extensions File extensions are the letters that follow the period in a file’s name. For example, in a file named document.doc, DOC is the file extension.

Calling All Parents and Educators of This Generation’s Digital Citizens. A few weeks ago, I was asked by a parent at my son’s school to share strategies on how to be conscious and aware of what their children were doing on the internet.
This immediately brought back memories of one of my favorite webinars on digital citizenship. If you missed it, you don’t have to miss out because it’s featured in Discovery Education. Access it here. (Canadian Subscribers). Discovery Education also has additional resources about Digital Citizenship. In the comment section, let us know how you work with families on strategies for working with this generation’s digital citizens. Our amazing presenter Devorah shared some final thoughts below. ————————————–The New Digital Citizenship Our kids’ future success will depend on true digital fluency.

15 Unusual (But Awesome) Websites to Use in the Classroom. By Jessica Sanders The Internet offers a seemingly endless amount of websites to explore.
A simple Google search for “coolest websites” provides dozens of lists, boasting handfuls of websites that you’ve never even heard of before. Use this list to spice up your usual collection of classroom websites, instead of returning time and time again to the same ones, and you’ll give your students an unforgettable learning experience, whether you’re exploring unknown lands or listening to the sounds of nature while doing work. 1.
