Its not making a sound out of the speaker connected (not the buzzer anymore.)
And I think theres no diodes in it,  except for that led.

I can hear it through the speaker,  it sounds like really quiet thunder that slowly dies off,   and on a good rekick,  it lasts for quite a while but its dieing off.

If I can improve the volume + evenness,  maybe it could last for longer as well!

And i can confirm that the diodes are unnescesary! =)

Most of us would describe your oscillator as a bad connection, or a noisy pot. :horse:
.  That took much longer than I thought it would.

If you really believe that an RC oscillator can't be built, you are not paying attention.  So watch and learn.

Why does your scope have Space Invaders at the bottom of the screen?

Where are we going, and why are we in a handbasket?

I just modified the resistor topology again,   and its slightly better,  but I got back from buying a pack of smegz from the local deli, and I got back and a wire was pulled out of its socket on my VPS!  wheres my tin foil hat!!! :scared:
