Oscilloscopes are surprisingly easy to use once you’re familiar with a few basic controls. They’re extremely useful for testing and can provide newcomers with a whole new way to view the world of electronics and electricity, plus they look impressively cool/awesome while in use!
I was lucky enough to score my own ‘scope during my early days of exploring electronics, and being a primarily ‘visual learner’, using the device was a bit like strapping on a jetpack of understanding/learning/discovery. So if you’ve ever been intimidated by the amount of knobs & switches on an oscilloscope … well don’t be. Find yourself a cheap used model to experiment with (they do show up @ tagsales and such), locate the basic controls I use in the above vid, and start investigating.
