Quadcopter using a Multiwii – Material
For some time now I have been getting a number of parts for the assembly of a X Quadcopter. Following the OOZ Labs tutorial i was gathering all the parts.
Prusa I3 Hephestos Assembly
One of the things we wanted to acquire, for some time, was a 3D printer. But taking into account the prices and maintenance I decided to assemble my own. I decided to assemble it because the cost is lower and when it is necessary to perform maintenance, i know exactly what part purchase, where to buy and how to replace it.
Temperature and Humidity Station with LCD
A few months ago i’ve presented a workshop about Arduino and decided to build a simple meteorological station. The station measure the temperature and humidity level, showing the values on a LCD and on a visual indicator. This indicator as three leds: one blue, one green and one red.

MongoDB on Raspberry Pi Model 1
One of my projects is to automate a LEGO City, especially the train section. For that i need a place to save all the information. Initially choose a SQL database (MySQL), but as necessary to create custom tables for each case and create relations. But as i didn’t know what information was supplied by the City and i would need a communication protocol ( i’ll use MQTT. In the future i’ll write a tutorial how to use it) i choose a NoSQl database, MongoDB.
RC Car Arduino Controlled
In this year Eletrónica e Informática (http://ei.aicb.pt) i presented a project prototype of an autonomous car controlled by an Arduino Nano.
The project was simple: a r/c car was controlled by an Arduino nano and uses an ultrasound sensor to detect obstacles that was in his front. If it was detected an obstacle, it stops, moves back and changed direction.
