this is one of the trouble shooting threads for the super simple oscillator if you have problems its a good place to start .

Getting the SUPER SIMPLE OSCILLATOR to oscillate

The SUPER SIMPLE OSCILLATOR keeps causing headaches, because while it’s a SUPER SIMPLE CIRCUIT (and SUPER CHEAP; the active component costs you a couple of cents) it’s not necessarily a SUPER SIMPLE BUILD, as can be seen in the recurring “oscillator trouble” threads in this forum. So I thought I’d post some suggestions for how to build the oscillator step by step, in a way that will at least tell you if you’ve managed to get it to oscillate. I’ve tested this with a variety of transistors, and h…
