WriterBot: build the attachment - ev3basic In this project we will design a pen attachment for the standard Lego 'driving base' model. This will include a medium motor that will lower the pen onto the paper when appropriate, and lift it off the paper when not needed. The design will make the pen touch the paper at the midpoint between the wheels - this will make the code much easier to write because it means the pen tip will remain stationary when the robot turns on the spot. I spent a number of hours designing a mechanism that can lower a pen into the ideal location, midway between the driving wheels, while maintaining compatibility with the standard Lego Driving Base model (also called the Educator Vehicle'). That means my pen mechanism is a simple add-on that can be attached to the Driving Base without dismantling the model. The trick was to have the pen held at an angle, as shown in the following photos (clickable):
Canadian Inventor Eden Full's Low-Tech Fix Solves Solar Power's Biggest Problem This article is part of a Huffington Post series, on the occasion of the site's 10th anniversary, looking at some of the people and issues that will shape the world in the next decade. Eden Full holds as much promise and potential as her name implies, and her mission is to save our metaphorical garden. At just 23, she's already an accomplished inventor who has dramatically increased the effectiveness of solar panels, landing her on Forbes' 30 Under 30: Energy list three years in a row.
5-Minute Film Festival: Resources for Filmmaking in the Classroom I'll admit I'm a bit biased here since I'm a filmmaker by trade, but I truly believe the process of planning and making videos can offer tremendous learning opportunities for students of almost any age. Not only is the idea of telling stories with video really engaging for many kids, filmmaking is ripe with opportunities to connect to almost every academic subject area. As the technology to shoot and edit films becomes more ubiquitous, where is a teacher with no experience in video production to begin? I've shared some resources below to help you and your students get started on making blockbusters of your own. Video Playlist: Student Filmmaking 101
Free Lego NXT MindStorms NXT-G Robotics Challenges Tutorials At the request of Tasmanian teachers Miss Clare Neilson and recently retired Mrs. Juanita Airey, activities using LEGO's NXT 1 MindStorms Robots have been developed for use in School-based 2-hour sessions. Some, but not all, will work with the new NXT 2 kit (click here for more information). The tutorials are presented as a series of Challenges, which are gradually being converted for Web use.
Ideas for Using Minecraft in the Classroom As is the nature of sandbox games, players can roam free, choosing objectives as they go. Because Minecraft has such open possibilities and potential, the teacher can choose how he or she wants to use it. Just as the student has the ability to be creative, the teacher has the same. That can be overwhelming, but luckily, there is a tool for using Minecraft created by teachers for teachers. MinecraftEdu provides a custom mod, basically a customized modification of the game, that helps facilitate organization and focus for teachers to use Minecraft effectively. In addition, Joel Levin, the founder of MinecraftEdu, provides ideas and updates at The Minecraft Teacher blog.
