NiHaoMike 8 Posted September 18, 2015 Share Posted September 18, 2015 I recently got a renewed interest in HD audio and decided to work with my best friend on an open source HD DAC. I selected MSP430 since it's easy to work with using Energia and an Arduino is overkill for what I'm using it for. (I normally use PICs, but then my friend, who is new to embedded programming, would have a hard time contributing.) https://github.com/NiHaoMike/OpenDAC-HD yosh, bluehash, Fmilburn and 2 others 5 Quote Link to post Share on other sites
spirilis 1,265 Posted September 18, 2015 Share Posted September 18, 2015 Is that totally using an old 3.5" HDD case as an enclosure? Freaking sweet! Quote Link to post Share on other sites
bluehash 1,581 Posted September 18, 2015 Share Posted September 18, 2015 Make a PCB. Make a PCB. Seriously..cool stuff! Is the drive motor being used for volume control, I cannot make it out. Quote Link to post Share on other sites

dubnet 238 Posted September 18, 2015 Share Posted September 18, 2015 Is it electronics, or is it art? Both! Took me back to the days of point to point construction used in old radios and TVs. spirilis 1 Quote Link to post Share on other sites
NiHaoMike 8 Posted September 19, 2015 Author Share Posted September 19, 2015 The volume control is a rotary encoder on the front panel. The motor was left in simply because it was too difficult to remove. Once the top cover is screwed on, the entire unit is quite well shielded. That "freestyle" construction method was good enough for Jim Williams. There are more pictures on the Github, including schematics, output waveform comparisons, and even a picture of my best friend and I holding the unit. tripwire and spirilis 2 Quote Link to post Share on other sites
