I am specially interested in things related to pinball machines. I am building my own machine. You can see pictures here: http://www.flickr.com/felipesanches and videos here: http://www.youtube.com/user/felipesanches
I am a co-founder and current president of the first brazilian hackerspace, Garoa Hacker Clube.
Currently I am travelling around Europe visiting hackerspaces. I will be in Vienna until September 3rd 2011, then Budapest until September 7th and Paris until September 12th. Then I fly back to Brazil.
I am also interested in any device listed here: http://libreplanet.org/wiki/LinuxLibre:Devices_that_require_non-free_firmware (for the purposes of reverse engineering them and implementing alternative firmware that respect software freedom)
