Gears Tutorial A complete tutorial on Lego gears, their advantages and disadvantages as well as the basic laws of mechanics that apply to them. Updated on February 19th 2010. When I describe my constructions or ideas, and when I explain their functionality, I usually assume that readers have the basic understanding of mechanics and of the rules that apply to gears. This assumption, it seems, is sometimes wrong. Neuroscientists Successfully Demonstrate Rat and Monkey ‘Brainets’ A team of neuroscientists at Duke University published two separate studies today, one involving rats and the other involving rhesus macaque monkeys, that describe experiments on networks of brains, or Brainets, and illustrate how such networks could be used to combine electrical outputs from the neurons of multiple animals to perform tasks. Monkey experiment: primates were seated in separate rooms, each facing a computer monitor showing the virtual avatar arm from a first person perspective. Image credit: Arjun Ramakrishnan et al. In the monkey experiment, Dr Miguel Nicolelis of the Duke University School of Medicine and his colleagues linked the brains of rhesus macaque monkeys, who worked together to control the movements of the arm of a virtual avatar on a digital display in front of them. Each animal controlled two of three dimensions of movement for the same arm as they guided it together to touch a moving target. Arjun Ramakrishnan et al. 2015.
Technology Integration Matrix The Technology Integration Matrix (TIM) illustrates how teachers can use technology to enhance learning for K-12 students. The TIM incorporates five interdependent characteristics of meaningful learning environments: active, constructive, goal directed (i.e., reflective), authentic, and collaborative (Jonassen, Howland, Moore, & Marra, 2003). The TIM associates five levels of technology integration (i.e., entry, adoption, adaptation, infusion, and transformation) with each of the five characteristics of meaningful learning environments. Together, the five levels of technology integration and the five characteristics of meaningful learning environments create a matrix of 25 cells as illustrated below. We appreciate your feedback.

Tutorial: Hopper NXT Hopper This little jumping robot jumps around on one foot with the help of a walking frame. Youtube viewers collectively suggested it reminded them of an old lady (I can’t blame them). To get a good idea of how it works, just have a look at the video, which is quite self-explanatory. If you have the NXT 1.0 kit, you’ll have all the pieces required to build this robot. NEW RESEARCH: More than half of the top 100 URLS are tracking you You’ve probably never heard of most of the 100 top URLs in world. In fact, most users have no idea that they’ve even accessed most of the 89 domains the average user interacts with in a month. A new F-Secure Labs study of the top 100 URLS accessed by customers all over the globe shows that of the world’s top URLs only 15% were accessed directly.
Best Free Video Converters What good is having a super-compressed MPEG4 video if you can’t watch it on whatever device you choose? Sure, that movie may look absolutely phenomenal in high-def on your computer, the resolution popping with the visual crispness and fidelity of real life, but it can be a pain to watch on your home console, or — if you want to cut the cord entirely — on your tablet or smartphone. Luckily, quality video converters have been around for several years, allowing users to convert their precious video footage into a number of desirable formats. And they’re completely free. Most video converters work in a similar way, requiring the user to upload their files and select an appropriate output setting before choosing a save location within their computer’s directory. Here are our picks for the best free video converters so you can free yourself from the ball-and-chain formats of yesterday and convert video so that it’s playable on practically any device you choose.
How to Make a Robot - Lesson 1: Getting Started Getting Started Welcome to the first installment of the Grand RobotShop Tutorial, a series of 10 lessons that will teach you how to make your own robot. This tutorial is aimed at anybody willing to get started in robotics and have a basic understanding of terms such as “voltage”, “current”, “motor”, and “sensors”. Although this might seem pretty basic, even people with previous robot building experience might find useful information regarding the general method of building a robot. What is a robot?
NXT Step Building Instructions We're compiling a list of Building Instructions for the NXT MINDSTORMS kit. Have you created your own building instructions or know of a fantastic website that has building instructions? Please let us know! DomaBot - www.damienkee.com A great robot to use in the classroom. Quick to build and plenty of places to mount sensors etc.
SORT3R, an EV3 brick sorter SORT3R, an EV3 brick sorter As I have a long record of building color sorters... for RCX, NXT and now for EV3! SORT3R can be built with a single 31313 EV3 set. Well, almost! The kit contains a capable color sensor, but no colored elements to use with it... So for SORT3R I used ubiquitous 2x4 bricks, in 6 colors: black, blue, red, yellow, black and white.
What is a 'computer' anymore? Technology It used to be a person. Now it's a machine. Limits of PivotTables in Excel PivotTables are interactive tables that quickly summarize, or cross-tabulate, large amounts of data. Within a PivotTable, you can rotate the rows and columns to see different summaries of the source data, filter the data by displaying different pages, or display the details for areas of interest. What Are the Limits of PivotTables? The following limits apply to PivotTables. Maximum Size There is no fixed maximum size.
