Low Pass Filter
I have been looking into building the GBZ, but I have been doing some research before I start. I understand most of the guide, but I am really confused on how to make the low pass filter. I have tried looking at wermy's guidehttp://www.sudomod.com/game-boy-zero-guide-part-5/, Adafruit's guide https://learn.adafruit.com/adding-basic ... o?view=all, and SP33's guide viewtopic.php?f=22&t=480but I don't know that much about electronics and am even more confused. Why does wermy's prototyping board have the angles/curves, when other ones don't? Anyone with an explanation?

Re: Low Pass Filter
You can use any style of prototype board, Wermy likely just happened to use one like that, I personally used a strip board, as long as you follow the diagram in SP33's guide you will be fine. Or like posted in the other thread you commented in, just buy the Kitchbent one.
The other option, is to skip the low pass filter all together, which I have done in my most recent build, and the audio seems fine. Or try USB audio, I haven't done that, but i've heard it sounds much better than PWM audio.

Re: Low Pass Filter
Easy way is to purchase some boards I made available on OSHPark for like $3PitchForkNinja wrote: ↑Tue Apr 25, 2017 5:26 pmI have been looking into building the GBZ, but I have been doing some research before I start.
