after getting a bit burnt out from working on my custom mp3 player, i went back to work on my older project, downbeat. after adding a bunch of features to downbeat, and FINALLY finishing it, i’m now back to work on my mp3 player! from now on, it should be known as the mochi player!

i also recently discovered a neat tool called cosmos.so that i started using for this project. it’s sorta like pinterest, but with a much better ux, and you can add images from anywhere. it’s actually really cool!

anyways, back to the actual tech. after working on naicha68 for a while now, i’ve gotten more experienced in pcb design, so i actually realized that my current setup might not be ideal. rather than having a codec chip to just handle all the audio decoding and processing, i was using a digital-to-analog converter, then manually playing the audio with the firmware. this would make designing the pcb a lot riskier, since there are more spots that could go wrong electrically.
i recently bought a adafruit vs1053 codec breakout board so i can test the vs1053 codec and write some firmware for it. this way, when i get the pcb, i should (theoretically) be able to just upload the firmware and have it work!

so yeah, i just got audio playing and the next step is to organize the filesystem in a neat way, and render some basic ui to the display!
