This is without doubt one of the most entertaining threads while also being the most difficult to read. I love it.

Dear Sirs engineers
As I slowly but surely approach the finishing of Pumpkin/shunty, I would like to take the opportunity by the horns and try to manage with serious measurements.
I am totaly newby in this matter.
Will you help me?
The conditions:
1.
I own an scope.
But no signal generator.
And square waves outputed by the PC sound card are not clean.
What should I do?
Trully yours

just set that drek by the book and enjoy ;
later - when you buy obladioblada outputin' thingie , you can measure and test everything ............... windows, doors , bleeekbleeek horns, Alephs, Pumpies ...... whatever you like

edit:
scusi if answer from non-engineer doesn't suit you .........

Aye Aye Captain,
I will behave this way because you're ma master,
(but later want little manu to learn measuring with scope)
BTW : Thank you very much for this nice Pumpkin Project.

It is not what you may think it is.
Its non-figurative art.
... And yes its nice

well - I didn't think anything ........ figurative ;
it's nice , without thinking .
damn nice .

Do you think it deserves a closer view?

pumpkin on +- 25v ?? Willit work OK?........

it will work on +/-24 , why not .......
Hey... I just noticed...... You didn't answer my question! .....geeezzzz

Sorry to interrupt all the intelligent discussions - and adding noise to the nice signal all of you have been generating.
Doing some calculations:
So if corner freq, F = 1/(2 x pi x R x C)
(where R = R1 X R2 / R1+R2, and R1=shunt resistor of output and R2 = input impedance of F4)
And if I use 3.3uF for C4, C5.
R = 100k x 47k / (147k) = 31973
therefore F = 1.51Hz?
So give a factor of 10 where it starts to fall off the curve - so my calculations shows that it is good for 15Hz?
Correct?

just shoot for it , besides-you can always place nice little Wima as bypass for output caps ...... ya know these little red thingies ..... 2u2/63V

But, but, but those little red thingies have already been soldered in and they are really tiny at u47/250V
