I have recently completed a project to compose tunes using EV3. I have produced project files for both the Retail 31313 set and for a combination of the Education Core and Expansion sets 45544 and 45560. The project uses two motors as angular sensors to control the pitch and duration of notes which ...

I've now added a second video, with a modified robot using an iphone camera.

Hi there I've had a bit of a lull on the forums, but in the last few days I have started playing with the Kleekbots system, principally because they introduced a very good sale price, which I thought was worth taking up. For those who haven't come across it, the system lets you remotely control a NX...

This looks really cool. I built aversion of the connect 4 game which used the colour sensor. see http://www.youtube.com/user/rbn1tube#p/u/2/UDi7ORELoSk and http://www.youtube.com/user/rbn1tube#p/u/1/ZOShrwxwgtc However it is tricky to set up and I much prefer your method which scans the whole board ...

Isn't this Danny Benedettelli's tic tac robot, from his LEGO MINDSTORMS NXT Thinking Robots book? I made it just after Christmas. As you say, a neat design, although quite fiddly to calibrate.

The best thing is that you can (graphically) analyse your data while your program is running. You'll find NXT2excel on my blog . Thanks for th...

You did post this on the ROBOTC forums :) Eventually. I joined the board but it took ages to send the confirmation email. Whilst waiting I posted here, then I also posted it there! It appears to be down this morning so I can't even see if there are any replies! Anyway, I've never managed to really ...

I should probably post this to the robotc board, but can anyone help with this problem. robotc has a system variable nDatalogSize which shows the size of memory allocated to store datalog files. The sample program supplied with robotc suggests that you can alter its value. e.g. const int kDatalogSiz...

At University of Cambridge there's an extremly cool project going on! They seems to use your Mindstorms NXT Toolbox for MATLAB with Octave, is it right? Well, inspired by this cool course, I've installed octave on my Mac and played with it, working through an excellent tutorial by Dr P.J.G. Long of...
