Cheap stereo line out I2S DAC for CircuitPython / Arduino synths

I am a big fan of these PCM5102A I2S DAC boards (3 for $15! affilliate) for playing around with audio synthesis, for example in this video about new `synthio` CircuitPython library or this repository about Mozzi Arduino synthesis. They have pretty high-quality audio output up to at least 16-bit @ 44.1kHz and separate out all …

QTPy-knob: Simple USB knob w/ CircuitPython

I like minimal solutions to problems. I was playing with a CircuitPython-enabled QT Py on a breadboard with and a rotary encoder and I ended up making a USB knob, like many others have done before. But I realized: waitaminute, I can literally just plug the encoder directly onto the QT Py… Thus was born [...]
