I have intensively been in for electronics and technology since I was thirteen. Since then I have spent twenty years of intensive work in the field of electronics (analog, digital, micro-controller programming, automatics, cybernetics…). I was lucky to have my parents support me from the very beginning, with literature, electronic instruments and material.
In the age fourteen I became a real fanatic obsessed with electronics, neglecting all the other aspects of life common for my generation. The common way of education didn’t suit me because it was inadequate for my needs, so I switched to my own system which made my learning fun and efficient. This self-schooling was based on theoretical research which I confirmed in practice afterwards. In case it was proven in practice that the device does not work according to the theory I thought I had conquered, I would get back to researching it until I would succeed in confirming the theory in practice.
Until the age of 17 I had won several gold medals in high-school category, the fondest of which to me is winning the first prize in automatics and cybernetics on the territory of former Yugoslavia (Slovenia, Croatia, Serbia, Macedonia, Kosovo, Bosnia and Herzegovina). This was, at the same time, a very important confirmation of the knowledge I had acquired and the correctness of my own studying methods, because I won in the area of electronics I didn’t have in school.
The project with which I won this competition was the remote-controlled model of a car controlled by a computer I had assembled. I had also written the program in the machine language for the Z80 microprocessor, as well as designed the interface and the drivers. This project provided me with a convincing victory because something like that was unseen at that time here.
After high-school, when I was 18, I went to serve the Army for a year, in Pula and Sibenik.
There I used the opportunity to study the newest electronic systems I ad access to. I had to use all kinds of ways to get the information about the electronics clamed to be the most advanced at the time, which alone evoked an unseen curiosity in me. In one of my last actions I was caught red-handed when I, out of curiosity, disassembled a rocket-launch system, the price of which was estimated to a $1.000.000. Fortunately, I succeeded to prove that my action was not to create a diversion, but was of educative character.
After serving the Army I did my first serious project.
The spectral sound analyzer was the device I designed when I was 19. It contains a great number of analog-digital filters controlled by a computer I assembled and designed especially for this purpose, as well as the algorithm in the operating system, written in the machine language, of course. 
It was a very effective device which multiplied the emotions felt while listening to music.
I spent six months designing this device and searching for the optimal characteristics which would enable a synchronized coupling between music, light and emotions evoked by music.
After designing this device I spent some time testing it with a rock group so I could get final results of the effect the device has on the audience.
Especially obsessed with artificial intelligence, I worked on purely theoretical projects. The vision of the electronic system for simulating the artificial intelligence was hard to achieve due to the element of emotions which would have to be woven into the system, without which the system would be just an expert system.
Mt previous ideas of expert and artificial intelligence systems brought me to the idea for designing the spectral sound analyzer.
The studying of emotions and the artificial intelligence, bio-feedback experiments, the attempt to embrace intellect with intellect al lead to psychic crisis due to which I left that research permanently. These crisis came because of the complete loss of creativity, that is, coming down to an average level of creativity, which I experienced as a catastrophe. When I was 22, due to the loss of creativity, I changed my way of living, starting repairing electronic devices (radio and TV sets, wireless phones, computers, professional slot-machines, gambling machines etc.). A year later I opened an official repair service for all kinds of electronic devices. In a short period of time the business developed so that I have to hire help. At the same time, one company from New Zealand offered me a visa and a job in the area of electronics. The obligations in my own business prevented me from taking the opportunity in time.
Shortly after that came a devastating inflation of the Yugoslavian currency, so the exchange rate was about 1DM per 1.000.000.000 dinars, and the average monthly pay was about 30DM.
My repair service couldn’t survive in such conditions because the electronic parts came from abroad, where the prices stayed the same.
With the beginning of war and dividing Yugoslavia (1991), I closed my business. After two years in repairs I got my creativity and the will for designing the electronic devices back, so I opened my unofficial laboratory for design and development. The first developing jobs were tied to casinos which, at that time, were the only ones with income. At the time (1993), a very large number of engineers and repairmen were unemployed and worked for the needs of casinos. Considering that I was late with joining that business, I had to offer new solutions which would get me jobs. In only a month, not just that I entered the business, but I also pushed all the leading engineers in my town out of the business. (Nis is flooded with engineers of electronics because of the "Electronic Industry of Nis")
This was provided to me by my good preparation and the possibilities I could offer because I was the programmer, the repairman, the electronic designer and the developer of the existing machines all at the same time.
The slot machines, and the poker machines of the Austrian "Tab-Austria" company flooded Yugoslavia at the time.
For the needs of casinos I developed a special type of an EPROM simulator and the system for it written in the machine language for the processor 6502.
With this program I easily broke the protection and fixed the programs, which was required of me by the owners (inputting the casinos’ commercials, programmable lowering of winnings, setting the stakes higher due to the inflation, networking the machines for remote controlling and accounting which could all be done by the owner from home using a modem, making special purpose viruses etc.).
I did this for a year after which period came the saturation of the market and the interest for these machines was no more.
The market value of these machines fell from 3000DM down to only 150DM.
By writing a completely new program for the micro-controller board of the poker machine (slot machine) and with minimum hardware changes (placed in a different case, of course) I turned a useless gambling machine into a powerful, 1500DM worth alarm system.
Encouraged by this success, as well as the economical logic, I continued transforming the gambling machines (especially using the micro-controller blocks and the monitors) into a series of completely different devices.
Those devices were firstly from the area of the traditional medicine, and then the modern medicine.
One of the really valuable and useful devices is "Vision I", which is proven multi-efficient applied in acupuncture. This is especially noticeable in acupuncture anesthetics.
After designing the "Vision I" device, I went to a medical fair in Belgrade to find a company to put "Vision I" in mass production. At the very beginning of the fair I got an offer from the "BIOTEHNA" company’s representative, that "BIOTEHNA" would take over "Vision I". Inexperienced in negotiations and administrative problems, and mostly out of curiosity, I decided to talk to other representatives at the fair.
I met with a manufacturer of medical equipment for rehabilitation and recreation. This manufacturer was not in alternative medicine, but "Vision I" interested them because it represented a highly automated device which proved me able to provide them with a high level of automation in their production program.
We drew up a contract according to which it was necessary to, in only a month, form the idea for the device for curing, rehabilitation and recreation of the spine, also design the measuring and regulation systems, write the operating system in the machine language (about 27kB) and, of course, realize it all. In exactly a month the product was realized and presented to the health department. After the successful tests, the Federal Ministry for Science and Technology helped this program with significant financial support.
The MDP company and the author of the device (I was hired to automate it), eng Milenko Pupovic, won the gold medal at the invention fair "INPEX XII" in Pittsburgh.
It is patented all over the world and the American patent number is: U.S. PAT. 5.609.566.
For this company I also designed the electronics for the intensive care bed. These electronics have an aim to enable the immobile patients to adjust the bed to different positions (for sitting, lying, eating, etc.) by a remote controller.
This bed is also patented in many countries, and in the U.S. under: U.S. PAT. 4.847.929. I designed the electronics for this bed also.
The both projects were quickly realized and put into mass production thanks to my wife, eng Ana Tomic.
From these projects further on I have worked only as a part of a team, which had been unusual before. I worked in the MDP company for more than a year, and after that period I decided to leave it permanently. The main reasons for such a decision was an insufficient motivation for work and an offer from a friend which helped me bring a life decision I had dwelled upon for years, whether to leave the country or not. Aware that the market is too small and poor for the products I dealt with, but then again not certain of it because I hadn’t checked it in practice (which is always right) wasn’t proper. So, before the final decision on leaving the country, I presented my products at the medical equipment fair.
This fair was in Belgrade, from April 23^rd until April 27^th 1996.
That was the 21^st international exhibition of medical and pharmaceutical equipment and devices, called "Medipharm 96".
There I presented my own products.
Those are the "Vision II", the sterilizer lamp, the "Ford’s lane" for nurses, the electronic stethoscope, the alarm device, and the reflex meter. I experienced the real teamwork when I was forced to finish all the products in 35 days due to the beginning of the fair and my obligations toward the MDP company (before leaving the company I had trained the new engineers for working with my projects for the electronics for the production program of the MDP).
I got the full support and help from my wife, girlfriend at the time. She worked on the reflex meter and the "Ford’s line". My parents and my brother made the plastic parts, casts, printing, my friends helped me with the booklets for the fair etc.
Besides all that, it was necessary to design a vacuum machine needed for the plastic parts. All these devices were home made, almost to the tiniest details (painting, printing, electronics designing, programming of the micro-controller board etc.). The products, although home made, and in a rush, weren’t below the quality of factory products.
Although I came through as a great designer and constructor, my conscious still burns because of the ones who helped me because I turned out to be a bad businessman and manager.
There was no authoring protection for my products, so the Bulgarian manufacturer copied my ideas and, with great advertising, and a much lower price started making sterilizer lamps, which didn’t even work properly because they used the ordinary tanning lamps, similar to the expensive and the only efficient Siemens sterilizer lamps.
Also, for this production program, great advertising fund is required, especially because the products are new.
For the "Ford’s lane" for nurses, the application of which would be very useful in Yugoslavian hospitals, I got an unofficial explanation from a high medical executive that any additional control of the extremely low-paid nurses would only lead to their revolt and strike.
"Vision II", useful in neuropsychiatry (because it contains the powerful reflex meters, the MIND machine for clinical evoking of epilepsy etc.) turned out useless, not because the attest wasn’t done due to the short time, but because they didn’t even have enough funds for common reflex hammers needed by every neuropsychiatrist, let alone for the electronic devices.
One by one, the devices were rejected, not because of technical, but sociological reasons, which I couldn’t influence as a constructor.
At this fair I met the real situation and the proportions of the crisis, as well as all the problems of the manufacturers.
The jobs of advertising and distributing the products didn’t leave any time for the jobs I like and know how to do, electronics and technology, but were only for businessmen and managers (the area which I find hard and boring). Right after the fair I did another project which I had not been able to finish for the fair (the dental camera). Although I knew that the market was uninterested in this camera, regardless its quality and low price, considering that I used one of my ideas to avoid using the expensive optical cables and adapters, I still finished this project.
However, there is interest for this camera.
The chairman of businessmen of Serbia  Dr med.Radojko Aksic, the famous Yugoslavian dentist with a private practice was interested in the project and gave me useful information about my dental camera (it was then for the first time that I found out about a similar product in the U.S.).
The knowledge of the camera already put into mass production in the U.S. was a great disappointment to me. The thought of the following jobs of presenting the new product, and all the problems connected to the poverty and meaninglessness of high-tech work in Yugoslavia kept me from the efforts of popularizing the dental camera.
As usual, my interest for my product stops when it is completed.
Numerous projects weren’t even mentioned here although there are a lot of more important and interesting projects (the pulse generator, the mural printer for extremely large formats which is small itself, the extremely powerful speaker of small dimensions, nothing like the existing speakers, a new way of filming large spaces etc.). These projects weren’t mentioned because the had not been realized in natural dimensions and conditions due to, for me, great development expenses.
The importance I give them is earned by the practical tests and positive results achieved with smaller models.
I mentioned the products I finished, which are used in practice, and the existence of which I can prove because I have almost all the prototypes.
Also, for some products, which I was hired to design, I can not mention them because I’m bonded by the contract.
Many projects I didn’t mention because this biography would be too long.
