My name is Rasoul Mojtahedzadeh. I was born and raised in Tehran, IRAN, land of the culture, science and professional poets. I was always an excellent student in school and loved science. While in high school I enrolled in an electronic appliances repairing school and I immediately fell in love with everything that I was learning about electronics. I built many electronic circuits and assembled many kits because I was really curious to find out how the circuits work. So I decided to go to university and learn all about the electrical and electronics theory and engineering tips and tricks. I am holding a bachelor's degree in electronics engineering from K.N.Toosi University of Technology in Tehran, IRAN.

I have been working in Automotive Electronic Systems Industry for 5 years. My speciality is Engine Control Unit (ECU). Actually my team at AESCO company, have developed the first generation of ECU for the biggest car maker in the Middle East Irankhodro company. Currently, I'm in Stockholm, Sweden to continue my education in Systems, Control and Robotics at KTH university.

   
  I have done many electronic projects and I am currently working in robotics field. Some of my works are listed below. If you have any question about me or the projects, please don't hesitate to contact me.

A concave-hull estimator.

This is the under developed concave-hull estimator algorithm to generate the best perceived shape for the given Dot Points.
   

950Mhz Frequency Counter
An accurate frequency counter based on ATmega8 microcontroller and a 10.000MHz TCXO .
   

LC-Meter
A LC-Meter based on AADE design one. It is implemented as an add-on for the Frequency Counter. The switches are replaced with miniature relays and they are controlled by the frequency counter.

A picture of actual connection between the LC-Meter and the Frequency Counter.
   

1~500MHz Wattmeter
A RF Wattmeter based on AD8307, Analog Devices low cost, DC - 500 MHz, 92 dB logarithmic amplifier. I found an article about it at ARRL website and decided to build it.
   



Dual Stepper Motor Controller
I made a dual stepper motor controller system to control an Air-Foil motion in the Air Tunnel of Aerospace Department of AmirKabir University of Technology.
