Homemade Volumio player with OLED display, I2S DAC, amp relay switch

Описание: Here is a DIY guide for a compact and light-weight Volumio player, running on Raspberry Pi Zero W. Has an OLED display for spectrum analyzer(using MPD_OLED plugin), a low-cost I2S DAC module, and an automated amplifier on/off function. The housing was designed in Fusion 360 for 3D printing and costs 30 US dollars or less in total to build.

IMPORTANT NOTICE
Procedures in this tutorial include handling of AC mains circuitry, albeit at a very simple level.
Please take measures to protect yourself and your device from any dangers involved.

Although the whole set of information for this project, including the source file for my design, is being shared, this video assumes some level of knowledge of electronics, Raspberry Pi projects, and general DIY skills: Visit my previous tutorials to get familiarized with similar projects and related technics, which you can find below.
