NXT Password Safe

For you that want security when keeping your stuff and don't wanna carry keys, this safe is the ideal one. Robotized with a NXT 2.0 set, it receives 5 passwords from 0 to 99 and, as long as all are correct, it opens automatically. After the opening and closing of the door, it locks automatically and ends the program. If an incorrect password is given, the program ends immediately. All the safe's "covering" was built with LEGO System & Duplo (only the bottom was made with cardboard, owing to lack of pieces...). Here's the video:

Hybrid Brick Sorter

Here is the first post with one of my robots: the Hybrid Brick Sorter, a robot which sorts standard LEGO bricks by color (green, blue, yellow and red) and by size (2x2 and 2x4). Building and programming step-by-step instructions following "The LEGO Mindstorms NXT 2.0 Discovery Book", but the "V2" was programmed entirely by me, only based on the original program. Built with just one NXT 2.0 set. Watch this video for further information:

Welcome to NXT Brazil!

Hello. Welcome to my blog, NXT Brazil. This blog is a door I'm trying to open for everyone, in Brazil or all over the world, that are already LEGO lovers (specially Mindstorms NXT) and those that want to meet this so fascinating toy. The blog will have a lot of models made by me, links for other fantastic websites about LEGO and a link for the Twitter that I'll also create for us to discuss everything about LEGO.
