Hello, I am from Slovakia, I study at Slovak University of Technology, Faculty of Electrical Engineering and Information Technology, Robotics. I liked electronics all my life, but only about half year ago, after sight of EEVblog, I started to pay more attention to electronics, I bought my first oscilloscope (Rigol DS1102E) on Daves recommendation and also bought my first real meter, Fluke 187, also on Daves recommendation. I could afford those, because I started to work at company, which does Process automation. The project I am just working on, is my Diploma thesis. After it is finished, it will be Developement kit for XBee with HMI. HMI will consist of 4*20 character LCD module, PIC micro (18f2320). encoder and few diodes. This whole solution should be used in learning process, to accustom student with XBee technology and to prevent them from connections and blowing up the XBee, or their circuits.
