Added a Raspberry Pi Zero W to an old radio to make a physical internet radio. The tuner output is routed into the Pi's microphone input and can be sent to the loudspeaker, or music can be streamed from the internet, a local NAS, or from an attachable USB storage.

I am seeing more and more people on various social platforms finally realize what a cancer Python is.

Me, a glorious embedded C programmer, who knew all along.

Might make a bike computer or add this to a set of garden sensors I made previously. These displays look great in full sunlight.

Set about playing with a cheapo e-paper display over the weekend. Waveshare has some great code for use with the STM32 that I adapted for use with STM32CubeIDE.

I could have chosen a better test image, though...

Set about talking to some WS2812 addressable LEDs over the weekend and made this demo up. There's a sheet of paper in front of the LEDs to make the colors more pronounced.
The processor is a cheap STM32F401 board which sends the whole string of all 7 LED colors to its PWM timer over DMA.
Colors are advanced every 10 ms. Every 1 ms, the colors are blended by a weighted average to smooth out the effect. Overall, the LEDs look like they update at 100 Hz.
