Now that we have my EV3 connected to Dropbox, let’s have some fun. In this project I use a cheap webcam connected to the EV3 to take a photo and upload it into my Dropbox account. It’s a wireless digital camera using the EV3 and Dropbox!
Here’s a quick tutorial to add Dropbox support into a Java program in leJOS 0.9.0. It turned out to be far easier than I thought! Read on to discover how you can easily upload and download files to and from your Dropbox account from the EV3 in leJOS. Dropbox? On the EV3? The first thing(…)
I received a review electronic copy of Packt Publishing’s ‘Lego Mindstorms EV3 Essentials’ book. This book covers Java and leJOS programming on the EV3, so it differs from most other books on the market in that it choose a 3rd party environment rather than relying on the Lego-supplied one. It also requires a Linux environment(…)
Sometimes it’s fun to just build something different for a change. Red Racer is my version of Sunsky’s lovely Snow White Racing Machine which I updated to use the new power functions servo for steering and medium motor for drive. I also styled it in red.

You won’t find detailed building instructions here, instead each model is presented in stunning colour with(…)
A blog reader asked if I had created building instructions for my Lego EV3 Space Invaders model. Unfortunately I never did create them before taking the model apart. But I did the next best thing; I took pictures as I took it apart! The Space Invaders model is broken down into 3 modules; the coin(…)

Space Invaders! The classic arcade game is back, and this time built using a single Lego Mindstorms EV3 kit. I decide to write this game in leJOS using the 0.8.1-beta release (see the leJOS wiki for more on getting it installed). I contemplated writing it in the EV3 graphical language but the thought of coding(…)
CHOPP3R is a search-and-rescue helicopter made from a single 31313 Lego Mindstorms EV3 set. I built this as a potential model for a book, but as the book has not materialised I decided to publish it instead! CHOPP3R has working top and rear rotors driven my a medium motor. It searches for a liferaft containing(…)
