my own original oscillator

Hey ArthurDent,  what is the mystery component.  Im not experienced enough to know yet.
And loved the vid thanks,  felt all warm and fuzzy inside.

PPl that just dont want to try things...   :-//

Yeh but the buzzer has a diode in it, it just went in by accident.  The other side is diodeless (double dioded) but I dont think it matters.

I actually want it without the diode as well.

If there is a buzzer, add it to your drawing.  Clear pictures, etc.   I have no problem trying to replicate your circuit but the first thing is I need a VERY clear understanding of what you have built.  As it stands now, I do not have that.   What you have shown in your first schematic shouldn't oscillate.   Then again, I have made a few oscillators that I would have thought wouldn't have as well.

Gunn diode, which behaves just like a neon bulb, just much faster and operates at much lower voltage.

Tunnel diode. Gunn diode is another story.

How does it show it doesnt oscillate.   Theres just another way to look at the circuit than the way I was when I designed it.

Heres the issue at hand.


charges capacitor
+ _w__________| |____out__ -


capacitor discharges on release of the positive pole,  battery bypasses capacitor, i dont want this.
                      _______     
                      |           z
+ __w_______|__| |__|__out___ -


extra negative connection  supplied, now current that takes the discharge path will be diverted from the output.
                             -
                             z
                      ____|__     
                     |           z
+ __________|__| |__|__out___ -


so, the issue u were having with me is this is equivilent:
       -                   
       z                     
       |               _______     
       |              |           z
+ __|________|__| |__|__out___ -


Im saying no worries bro you might be right.



And why it works more info:

this is ONE HALF.
  INVERTER WIRE
    -
    |  -
    |  z                     
    |  |               _______     
    |  |              |           z
+ |_|________|__| |__|__out___ -


Then the second half is the first halfs inverter, and vice versa.

So they are inverting each other.


    -
    z
    |------------------ feedback inversion
    |-----------------+ (gutter pole, what i called it,  in the position you put it)
    |------
   ___    |
   ___    |
    |------
    |
    |  -(gutter pole - where u put it.)
    |  z                     
    |  |               _______     
    |  |              |           z
+ |_|________|__| |__|__gotofeedbackinverter___ -



So you can see quite humourously,  that each side is inverting the other.

Gaaahhh!  Please don't do that. Just sketch and photograph, like you did before.

Yes, there is a slight element of "hazing" or "jumping in" going on here but what did you expect, really? There are thousands of examples of correctly sketched simple schematics on this site to look at, there is even "DaveCAD" .  So when you come onto a new block you really should at least try to speak the idiom, feel me? Use standard symbols so we can understand what you are communicating, and be ready to put up with a little mockery, as you are learning.

What does your "buzzer" element do if it is just connected directly to the battery?
