Cool Project: EV3 and NXT over WiFi

featured-wifi-ev3-nxt

One of my readers, Elias Barcia, mailed me back in May 2013 to ask for some input for a university project he was working on: make the three generations of MINDSTORMS, RCX, NXT and EV3 communicate with eachother.  I gave him some feedback and pointers and some time passed.  I had all but forgotten about it until he mailed me ...

LEGO MINDSTORMS EV3 Windows Themes

featured-mindstorms-theme

I downloaded most of these background pictures from the LEGO EDUCATION website via some Google searching.  They’re very nice high-res images of their models.  The reason I picked the LEGO EDUCATION images is because they’re less busy than the retail ones and have a beautifully clean, uncluttered and white background.  Both these themes are essentially the same but one uses ...

Tristan from Tris10.com (yeah, very clever domain name!) sent me a FindBall NXT and EmitIR to play with and write a ROBOTC driver for. The FindBall NXT The FindBall NXT is a sensor specifically made to locate a 40KHz modulated IR signal, as used by the RoboCup Junior balls.  Tris10 claim that it is currently the best sensor for this ...

Virtually Awesome: Virtual NXT

featured-virtualnxt

Robotics is great but if you have a lot of kids that want to take part, you’re going to need a fairly large number of sets.  You don’t want to have spend the first 15 minutes of each class rebuilding the base robot for the lessons of that day. Up until now, you could use the ROBOTC Virtual Worlds, which ... Read More »

Review: Instant LEGO MINDSTORMS EV3

A little while ago, I was asked by Packt Publishing to review one of their new e-books called “Instant LEGO MINDSTORMS EV3” by Gary Garber.  It’s a small (82 pages) e-book that is “A concise guide full of step-by-step recipes to teach you how to build and program an advanced robot.”  It aims to be usable for both an experienced ...

Setting up a Wi-Fi AP on your Computer: Part 2

Virtual_Router_Manager_v1.png

Virtual Router Manager In an earlier article, I had written about how to allow your EV3 to connect to your laptop (or desktop) with a shared WiFi network, using a feature called Hosted Network.  It essentially turns your computer into an Access Point (AP).  Since then I’ve had a bit more experience with it and I’ve found a very easy ...

EV3: Adding a pull-tab to your micro-SD card

featured-ev3-tabmicrosd

The EV3 has a lot of cool features but a push-to-eject micro-SD card drive isn’t one of them.  It’s fine for users who don’t work with custom Linux distributions on their brick, but a major PITA (no, not the Döner Kebab kind) if you’re like me.  It takes a needle nose pliers and a lot of patience to remove the ...

Breathtaking: Debian Wheezy on the EV3!

2013-10-27-16-cropped.jpg

Ralph Hempel is no stranger to MINDSTORMS and he’s been quietly working on something very special: a port of Debian Wheezy on the EV3.  The folks of the Debian organisation wouldn’t let him use the Debian name (for copyright reasons), so this project is called ev3dev. What is ev3dev? It’s a complete Linux distribution for the EV3.  What do I ... Read More »

Talking to your EV3: EV3Messenger

20131019_135648.png

I was contacted Joeri van Belle last week about a new project that he is working on, a C# project that allows you to send messages to your EV3.  Using it, you can send and receive messages between your EV3 brick and PC. On the brick you can use the standard BT communication blocks, so you can do this without ... Read More »
