RSS Bot Posted February 17, 2023 Share Posted February 17, 2023 I don’t think I’ve ever written about open-source hardware headphones. But that’s precisely what Ploopy offers with an amplifier based on a Raspberry Pi RP2040, a Texas Instruments PCM3060 24-bit DAC, and an amplifier circuit, as well as 3D printed parts and open-source firmware written in C. As we’ll see further below the project is reasonably well documented, and you can either build it from scratch, purchase a fully-assembled kit, or something in the middle. I suppose you could even do some knitting since woven covers are part of the build just in case making your own PCBs and 3D printing parts are not your things. The electronics are comprised of two boards: The Gould amplifier board with the Raspberry Pi RP2040, Texas Instruments PCM3060 24-bit 96/192 kHz DAC, and several TI OPA1688 audio operational amplifiers The Mazzoleni driver flex boards going into the left and right rings with a [...] The post Ploopy – 3D printed open-source hardware headphones feature Raspberry Pi RP2040 MCU, TI PCM3060 24-bit DAC appeared first on CNX Software - Embedded Systems News.
