Many of us plan to turn Raspberry Pi or a similar single-board computer into a retro music player. There are several projects that we discussed using Raspberry Pi as a controller to build an 80s style music player. However, these projects use bulky hardware, which may not be as portable as this one. Chinese designer […]

joesugar @ ceworkbench.wordpress.com has designed a S/PDIF Sound Card using the PCM2906 IC. In the belief that I’d rather build than buy I decided to update one of my previous projects, a PCM2904 based sound card, to include an S/PDIF interface. The update was a cinch because TI has a pin-for-pin replacement for the PCM2904 (the […]

Tomasz Ostrowski has tested some cheap USB sound cards as low speed oscilloscope interfaces/recorders. He writes: I’ve tested some cheap ($1) USB sound cards for DC sampling capability, in particular for using as low speed oscilloscope/signal recorder. Some (http://tomeko.net/dsoundscope/c_media.php or one from this thread: http://www.elektroda.pl/rtvforum/topic3106124.html) don’t seem to work despite removing DC blocking capacitor, but […]
