I was trying to make a low pass filter

Not that I'm an electro genius, but I rather think that's quite a strange low pass filter.
Normally, a low pass filter is a capacitor serially connected to the thing you want to connect to the filter, and a resistor parallel connected to that.
And a high pass filter is a resistor serially connected to it and a capacitor parallel connected.
And eh, (or it might be vice versa)
-edit- Well, I think I saw it wrong

I used "crocodile clips" a couple of years ago to experiment with such, maybe you can download an evaluation version of that somewhere to check...
(I'm not going to calculate to check for errors in this whole thing atm)

I understand, but eventually you'll discover it's just a hell of a lot work
Good to understand electrics, though :-)
