Xander Soldaat from BotBench will be doing a Presentation on MINDSTORMS NXT on 8 September in Rijswijk, the Netherlands. Apart from talking about MINDSTORMS and its hardware, he'll also bring some of his NXT creations.
The presentation will be held at a conference center in Rijswijk, with free entrance. More information about the presentation and signing up can be found here.
Whether you don't have an NXT or whether you're an experienced user, it will surely be an interesting presentation. Before and after, there will be plenty of time to talk with other people on how they use Mindstorms.
I'll be around too, see you there!
