dsaylingI dig and buy a lot of gizmos, like a EM meter a Geiger counter, dacs bulb amplifiers, tools etc... I saw this and looks pretty neat but I am completely ignorant of what kind of uses this item has does it have any practical applications for a regular Joe like me?
MonetUnless you actively work with electronics, it's pretty useless. Oscilloscopes are used to visualize variations in electrical signals. So like a multimeter, it will measure the voltage of signal, but displays it graphically so you can see the actual waveform of the electrical signal.
