Voja Antonić

Voja Antonić (Serbian: "Воја Антонић", "pronounced Voya Antonich", IPA2|'ʋɔja 'antɔniʨ) is a Serbian inventor, journalist and writer. He was also a magazine editor and contributed to a number of radio shows but he is best known for creating a build-it-yourself home computer Galaksija and originating a related "Build your own computer Galaksija" initiative with Dejan Ristanović. The result of this initiative is, perhaps, his crowning achievement - he encouraged and enlightened thousands of computer enthusiasts during 1980s. Mr Antonić donated many of his personally initiated creations to the public domain, whenever they related to the common man or a fellow engineer.

Notable Electronics Projects

1976. Conway's Game of Life

After reading a book on Z80 microprocessor motivated Voja Antonić to create something with it. His first creation with a microprocessor was Conway's Game of Life machine that shows its state using 8x8 matrix of red LEDs. The machine reportedly worked flawlessly almost continuously since creation to at least 2006 (time of writing of this article).

Pictures and descriptions (in Serbian language) can be found on [http://www.paralax.co.yu/pr76.htm his web site] .

1981. Sport Event Arbitration System

Prior to the Winter of 1981/1982 [http://www.skijanje.co.yu/Takmicenja/klubovi.htm Smučarski savez Srbije] (en. Skiing federation of Serbia) timed the competitors using regular stopwatches and hand signalling. Upcoming Balkan competition required this to be improved and more precise and the skiing federation contacted Mr. Antonić to create a system for precisely timing each competitor.

The result was a small, battery powered computer packed together with Liquid crystal display 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 to come.

1982. Alarm System

1983. Galaksija

In 1983 Mr. Antonić learned of the interesting way to have the CPU generate video signal, without the use of specialized video circuitry. He thought of this as a good idea for an inexpensive, "build-it-yourself" computer. "Galaksija" (pronounced Galaxiya, meaning Galaxy) was featured in the special edition Računari u vašoj kući (Computers in your home) of a popular science magazine of the same name, published late December 1983 in Belgrade, Yugoslavia.

Voja Antonić essentially released Galaksija to public domain and never required any compensation for it. He wanted it to be a project anyone can undertake and received only the compensation for writing the magazine "article" itself, not the computer.

Initial estimates were that between 100 to at most 1000 Galaksijas will be built. End result was at least 8,000.

----Actually, there is alternative history of Galaksija startup connected with 6502 and ZX81 video generating code and hardware. I will write it soon. Promise.----

1993. Digital Photo Printer

1999. Engineer's Assistant

In 1999 Voja Antonić created a logic analyzer, probe, serial interface receiver and frequency counter device based on Microchip Technology PIC16F84 microcontroller. It eventually became Microchip's "application note 689" (AN689) but was subsequently removed. Although the work was published, compensation for his efforts, Microchip in-circuit emulator "MPLAB-ICE 1000" was never sent to Mr. Antonić. Microchip claimed that it was prevented by ongoing sanctions against Yugoslavia.

Do nonexistent things exist? - a guide to critical thinking

Increases in superstition and popularity of various fortune tellers at the very end of 20th century prompted the sceptic in Voja Antonić to try to do something about it. He decided that the best way is to write his first book, "Da li postoje stvari koje ne postoje - vodič za kritičko razmišljanje" (Serbian language, ISBN 86-902159-1-3). Excerpts can be found on [http://www.paralax.co.yu/knjiga.htm author's personal web site] .

To provoke interest, the book was packaged with a "dowsing pendulum" alongside the binding edge of the book. As per author's own word, this was done to make just an appearance of controversy. A chapter of the book deals with ideomotor effect and explains how there is nothing controversial about it.

Non-Prophecy from Kremna - a study of deception

Continuing his sceptical interest in fortune telling, Voja Antonić took action against a prophecy popular in Serbia, made by self-proclaimed prophets Miloš and Mitar Tarabić from Kremna village by the city of Užice. He uncovered that twelve issues of the book Prophecy from Kremna were all different and altered over time.

During his research he visited Kremna where he was offered the "original handwritings" of Mitar Tarabić, who was illiterate.

Name of original (in Serbian language): "Kremansko neproročanstvo: studija jedne obmane", ISBN 86-902159-2-1. Excerpts can be found on [http://www.paralax.co.yu/kp.htm author's personal web site] .

Patents that won't change the World

Being a proven inventor, Voja Antonić took pleasure in browsing other people's inventions and patents. He could not avoid noticing that many patents are at the very least naïve or just impossible. To top it all, he wanted to address the increasing appearance of people referring to patent applications as if they were actual patents. The result is yet another book, currently only (freely) available in electronic form, on [http://www.paralax.co.yu/patenti.htm author's personal web site] (in Serbian language).

Possibly related to this book, Voja Antonić humorously presents how to build a "Vampire detector" on [http://www.paralax.co.yu/pr00.htm his personal web site] . The periscope-like device exploits the assumption that vampires do not have a reflection in the mirror and allows the operator (viewer) to quickly and easily switch between the straight-through and periscope views. He states that he will not apply for a patent because "Albert Einstein is no longer working in the patent office and nobody else would be capable of understanding the true value of this invention".

hort stories

Voja Antonić wrote a number of short stories for his appearances in "Modulacije" (eng. "Modulations") radio show hosted by Zoran Modli. He personally read them during live public broadcasts. Later he made them available on [http://www.paralax.co.yu/price.htm his web site] (in Serbian language).
