Breadboard and meter a circuit.

[Lightium]

Does somebody want to breadboard my circuit and measure the output with oscilloscope?

 

[Nigel Goodwin]

Well it looks completely non-functional, what's with Q2 base/emitter?.

 

[Lightium]

Oh no, it oscillates at a variety of frequencies.

 

[Lightium]

Q2? The power supply is so small there is no need for biasing.

Q2? The power supply is so small there is no need for biasing.

Q2 base emitter junction connects the supply directly to the top of R2, so the emitter of Q1 is only 0.7V below it's collector, with 2.3V just wasted across R2. I'm doubtful if it will work on only 0.7V, but in any case why use a 3V supply and throw 2.3V of it away?

mmm, I'll keep going and look at what you say and fix it.
