I want to design a basic Oscillator circuit with an NPN transistor. My predictions: When C1 charges up to 0.7 volts, it will open up the npn transistor and allow 3 v dc to flow to the LED. C1 is then discharged and the process repeats itself. My schematic:

I want to take an audio signal, and shift the waveform 180 degrees. How would I do this? I have read that if you take a simple class a amplifier, and feed the signal into the base of the NPN transistor, you will get an output that is shifted 180 degress. Example: Will this work?
