This was my second task given by university, the task was to develop a working pair of traffic lights using only logic gates, counter and 555 timer. To get higher grade you have to design the system with least amount of chips.
First commercial electronics project I've had. Basically the company had this problem, that emplyees knew when to have a break but somehow always forgat when it finishes. Well, the company asked me if I can make a system which controls the bells in their company.
For a contest to get to space center in USA I developed a game called "Puzzle of planets" in like two weeks. It is a simple game where you have to put together peaces of planets, after you complete the puzzle, it shows you information about the planet, like when it was discovered, how big it is and other intersting facts.
Again one of my unfinished projects. Basically what I wanted to make is a smart room where I can control the music and light in the room wirelessly through web interface. Not only that, my vision was that there would be a built in embedded system in the wall, so I made a light weight stand alone app as well.
