	tl;dr: Frustrated by the loss of album artwork in the streaming era, the author built "Pentaton LP," a 12"x12" AirPlay streamer featuring a 17" 1920x1920 IPS display designed to mimic a vinyl sleeve on display. The project required learning PCB design (a custom carrier board for a Radxa CM3), FreeCAD modeling, 3D printing, and low-level Linux work, plus a custom protocol extension to bypass AirPlay's low-resolution (500x500) artwork limitation. The device idles under 2W, wakes on streaming, and triggers the amplifier automatically; a Kickstarter is being considered.
	HN Discussion: ↑Admiration for the project with curiosity about specific technical details or challenges ↑Enthusiasm for the concept and interest in buying or expanding features like lyrics •Questions about learning hardware skills and sourcing components as a hobbyist ↓Suggests simpler alternative solutions like a Mini PC with foobar2000 would suffice •Tangential reflection on PCB manufacturing accessibility and local fabrication shops
