Vojislav "Voja" Antonić (, ʾ, 12 July 1952) 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. Biography While in school, Voja Antonić found a passion for HAM radios. He obtained a licence and a callsign to broadcast his own waves. One day, the state police seized all CB Band units known to operate in the country, creating a new trend for HAM radio units which bored Voja Antonić who decided to move on towards new digital technologies. His first creation with a microprocessor was Conway's Game of Life machine which shows its state using 16x16 matrix of red LEDs. Without a computer, Voja Antonić wrote the code on paper and operated the input in the system byte by byte using rotary switches. LEDs being expensive back then, it took him months to buy and install the last LEDs. A replica of his machine reportedly worked flawlessly almost continuously for 40 years. When personal computers arrived on the market, they were not accessible in Yugoslavia. Voja Antonić asked a friend in the USA to disassemble a TRS-80 Model I and send it to him and received it labelled as "technical junk". He received it, reassembled it, and started his new computer passion. While studying at the Faculty of Dramatic Arts in the late 1970s, he started to build computer systems capable of rendering animations. Prior to the Winter of 1981/1982, the Skiing Federation of Serbia timed the competitors using regular stopwatches and hand signaling. The upcoming Balkan competition required this to be improved and more precise. In 1981, Antonić created a small, battery powered computer packed together with liquid crystal display, printer and keyboard in Samsonite suitcases. Over the years five different models were built, named from "Arbitar" to "Arbitar 5", and were used for many years. In 1982, he designed an alarm system for Elektronika inženjering. While on holiday in Risan, Montenegro in 1983, Antonić learned of the interesting way to have the CPU generate video signal, using an Zilog Z80A microprocessor instead
