worst working oscillator

bad things:
* frequency is dependent on transistor gain, 
  the most variable thing in the circuit
* giant inductor required to maintain 
  oscillation
* the transistor must have high gain, 
  or the inductor must be even larger
* because the frequency is dependent on
  transtitor gain, it logically must also depend 
  on the inductor's parasitic resistance
* it might also depend on the transistor's 
  parasitic capacitance

I invented this kind of oscillator years ago, but the best resonance is on higher frequencies check this http://everycircuit.com/circuit/4598437118214144

@hurz: Nice! Yours isn't dependant on the gain at all, which is good. The current flow is interesting, much different to mine.

I dont expect that thing is working in real. Give it a try http://everycircuit.com/circuit/6696002877915136

ahahaha! @hurz: at high speed, it's basically a Pierce oscillator with one of the capacitors being parasitic capacitance in the transistor. My link above is identical in structure to this: http://everycircuit.com/circuit/5282621172219904
