An open source universal audio amplifier called ‘U-AMP‘ @ GmanModz, that is available on GitHub: Using what I learned getting digital audio working on each systems, I set out on a new project I would call “U-AMP” (Universal-Amp). This would be ONE pcb which has the features of seamlessly integrated speakers and headphones with a […]
Audio DAC for Raspberry Pi
https://www.electronics-lab.com/audio-dac-raspberry-pi/
Small single-board computers like the Raspberry Pi are ideal for use as small stand-alone network audio players. With Volumio and other specialized Linux distributions, putting together an audio player is remarkably easy. And as Elektor staff member Ton Giesberts shows in the referred article, you can also use this approach to build a high-end audio […]
