Voja Antonić, Serbian computer scientist and journalist, designed the Galaksija computer

Vojislav "Voja" Antonić is a Serbian inventor, journalist, and writer. He is known for creating a build-it-yourself home computer Galaksija and originating a related "Build your own computer Galaksija" initiative with Dejan Ristanović. This initiative encouraged and enlightened thousands of computer enthusiasts during the 1980s in the Socialist Federal Republic of Yugoslavia. Antonić has donated many of his personal creations to the public domain. He was also a magazine editor and contributed to a number of radio shows.

The Galaksija was a build-it-yourself computer designed by Voja Antonić. It was featured in the special edition Računari u vašoj kući of a popular eponymous science magazine, published late December 1983 in Belgrade, Yugoslavia. Kits were available but not required as it could be built entirely out of standard off-the-shelf parts. It was later also available in complete form.
