So, this is the back side of the lowpass filter I designed. It's nothing special and yes, I know my work down here breaks like 10 billion soldering and development rules (Such as using the legs of the components instead of wire and my solder beads being not great) But part of why I am doing these experiments are for learning how to solder properly, as I haven't been taught how to properly.

You also might realize that I forgot to add an output from the odd placement of the two audio jacks. In fact, I initially built this filter so it was filtering and bypassing all forms of potential output and had to fix it, which may have been easy, but it was annoying.

I made this last night at around 11PM and finished around 11:45, so I was a little tired and didn't pay too much attention to perfecting it. Now, if I ever design these for sale, I will do far better, but since this is a prototype, all that matters is that it is a working proof of concept in my eyes!
