Firstly, I am starting my senior year in Electrical Engineering once school starts, and I feel that I am in dire need of some more "hands on" experience with the equipment. At my uni, the EE degree is split up into a Physics path, and a technology path. I'm thinking that may be a bad idea though, because most of my class mates (in the Physics program) are surprisingly inexperienced with most of the equipment. At any rate, I would like to start playing around with circuits at home. I have breadboards readily available, resistors, diodes, mosfets, opamps, basic electronic devices like that. My biggest question is: Power supply. I could try a 9v battery, per se, but how "ideal" of a source would that be? Also, that seems pretty inconvenient. Also, perhaps something like an oscilloscope? I realize these cost thousands of dollars, but isn't there any software I can use to read an output signal, for example? At home, I also have a device to measure resistance, voltage, current, and probably some other stuff I'm not aware of. I'm afraid to call it what I think it is (multimeter), because I always hear a new name for it. That is a clear indicator of my technical inexperience, so I would really take any advice/comments I can get. Thanks in advance.
