Interesso-me por ciencias exatas de um modo geral Deste foguetes ate astronomia Desde construcao de telescopios ate polimento de espelhos amadores. Desde eletronica ate.Home science -- I like exact sciences in general. I played a bit with home made rockets, homemade telescope mirrors, and recently diy RC gliders. Love electronics (arduino) and love photography too.
