I still don't understand properly what an oscillator IS... I know its switching back and forth SOMETHING multiple times a second... but I do not understand its applications... maybe wait a few more months and they will teach us in electronics class? They just asked us to throw together about 3 oscillators and did not tell us how it works (though I already knew, wtf is its application??? I can't learn just from a few blinken LEDs, I need some explanational text, speech or video. XD so someone please explain to me what an oscillators function is because mr. scime will not tell us and the only girl in that period. :P he did give us a bipolar LED which I found quite an oxymoron...

An oscillator's purpose in life is to take boring old DC current and change it into AC. Once something is AC, you can use that to switch a MOSFET, to step up or step down voltage of your choosing. It is the basic principle behind almost all SMPS topologies.

Different oscillators using different components allow for versatility. Simplicity and efficiency are things that come to mind when choosing an oscillator.
