Been learning more about DSP design for audio. It's really interesting because for what I am wanting to build, an anaolog guitar pedal can be conceptualized as a black box ASIC.
Been trying to learn more about the people who lived where I do now, but 1000s of years ago after seeing an ancient mound on a hime a week ago.
It's been pretty mind blowing. I live in America so it's not as easy it as is in many other parts of the world.
There is an ancient structure nearby that was levelled to make a paper factory. When that factory was torn down, the only artifact from that site was recovered.
