My Omniwheel Article in D&T Practice


A little while ago I was asked to write a robotics article for the British Design & Technology Practice magazine.  I chose to cover the basics of programming a LEGO MINDSTORMS NXT omniwheel based platform, and the mathematics behind it.  ROBOTC is used as the programming language, but I am sure the principles apply to other programming environments, too.  Although, I ...

Pi Uninterrupted: OpenElectrons PiUPS


Deepak and Nitin Patil from Mindsensors have created another awesome Kickstarter project under the OpenEelectrons.com flag: the PiUPS, an uninterruptable power supply for the Raspberry Pi in a very compact package. It’s an inline power supply system that constantly charges the backup batteries when it’s connected to the mains or another external power source.  When this external power source gets disconnected, ...

If you are involved in LEGO Education, then this may be the perfect place for you to discuss with your peers.  Below is a copy and paste of the original invitation.  The target audience includes parents involved in FLL and people with a general interest in learning and using LEGO in learning, so teachers and other educators.  However, due to ...

EV3 Build Your Own Block and HDK/SDK Docs Available


These files have existed for a little while now but I never got the official OK to distribute them.  However, one of my readers (Marius Steffen) was given two Dropbox links via LEGO Customer Support to these specific files.  That must mean that the documentation is no longer under NDA and so I now feel no reason not share them ...

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 ...

Virtually Awesome: Virtual NXT


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 »



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 ...

EV3 Supply Issues


It seems that “due to unprecedented demand”, there is a world-wide shortage of EV3 hardware.  This seems to affect the Educational set which some of LEGO’s distributors are marking as out of stock until March 2014.  I currently have no info on what the situation is on the retail EV3 set.  I’ll update when I know more. I am surprised ... Read More »

Review: The LEGO Build-it Book – Volume 1


As most of my readers know, I am not much of a studded LEGO builder, most of my creations are Technic studless LEGO.  When Starch approached me to review this book I wasn’t sure how I was going to be able to do build any of the models in it.  Lucky for me, the models in this book are mostly ...
