I am Ben-Hur Gonçalves, a mechatronic engineer graduated in São Paulo University, São Paulo state, in Brazil (2009). I am the owner of a construction company.

However, I am also a maker of Drones, Arduino and electronic projects, and I like stuff as microprocessors, robotics and technology. I want to share knowledge about how to make DIY (do-it-yourself) projects and the common issues you will find making them. I also have an Instructable page and a blog with my projects. You can also follow me on Twitter @Ben_Goncalves, or Google Plus here. More about me:

I graduated on Universidade de São Paulo (USP), Brazil. Before college I was:

– Golden medalist on Brazilian Olympiad on Astronomy (2004);
– Bronze medalist on Brazilian Olympiad on Physics (2004).
