Hey HN,

I've finally finished my dream music streamer featuring a vinyl-sleeve-sized square display, a custom carrier PCB for a compute module and a 3D printed case, running a custom-compiled kernel, Alpine mini rootfs and a small C app driving the display.

I did not think that this was doable by a hobbyist at all, let alone using free/open source software only (KiCAD, FreeCAD, VSCode). Turns out I was wrong!

My passion project is an LP-sleeve-sized music streamer built around an ARM compute module, a custom PCB carrier board and an industrial 17" square display.

Hey HN! I always liked to see and touch the cover artwork of the CDs and LPs I bought in the past, but in the end the convenience of digital streaming won me over and I accepted no (or stamp-sized) artwork. Lately I’ve been missing this more and more and ultimately decided to try to do something about it. So I built a streamer from the ground up.

Happy to answer any questions, this is my first PCB design and 3D model all in one project.
