my own original oscillator
alsetalokin4017:
I think bsfeechannel has the correct explanation. Ian.M has also described "oscillators" that I have encountered. Faulty connections to the die that are intermittent can really drive one crazy. It's good to have substitute parts to swap out when puzzling events like that happen.
But I love a ring oscillator. Especially when they run on "free energy" LOL.

joeqsmith, you stole my idea of a spark gap oscillator! I have the capacitor I used in the circuit as proof! 8)

I just saw on this site that ham radio was dead in 2019.

Nice! Every hobbyist needs a few of these in there stash.

Haha you guys are really funny.
Thanks Joe Smith again, for redrawing the schematic to a more professional topology. I saved a png to my hard disk just for something to remember.
I dont know what's going on, I dont even know what im supposed to post next to be on this forum, we dont share what we know? I dont understand.
The spark gap oscillator was great, that must be the simplest oscillator of all.
AlsoToken, thanks for showing me your work, too, but this electronics business doesnt seem like programming the way ppl are constantly kidding around I had no idea about it going to be this way.
I see that you have a capacitor based oscillator as well!!!! but urs looks dif.(better) thanks.
So my idea isnt new? I wish ppl would just tell me...
Rerouter:
Currently the majority of the thread seems to suspect it is either the buzzer being the non linear element or that there is a defect in a LED that is letting it act like a spark gap or to be more precise. Similar to a bimetallic regulator where it heats up breaks connection then cools down and repeats
Remove the buzzer and replace both LEDs with new ones and we can rule out both of those options.
Most of the derailment of the thread came about because at first glance the circuit does not make sense in how it could oscillate. It takes something misbehaving to fit most of the current expected thoughts on how it operates
As such I think it triggered some of the people that reguarly have to debunk impossible devices such as free energy scam circuits. And in such cases engineers tend to attack with sarcasm.
