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 …

Speed up CircuitPython LED animations 10x!

In many LED animations, you need to apply an operation to all LEDs as fast as possible. Often this is “fadeToBlackBy”, i.e. “dim all LEDs by some amount”. There are some common effects that you can easily get back using that and one other action. For example: the Cylon effect is “Turn an LED on, [...]
