       @blog This is one of the reasons I like Flakes because everything is sandboxed by default. You can clone, build and run one with a single command now and you also don't need NixOS because Flakes will run on any distro and even macOS.

       If you have a spare Raspberry Pi Pico then with a few jumper wires you have yourself a high bandwidth logic analyser (a digital oscilloscope). This is thanks to the open source Sigrok project who make the PulseView app. This was extremely useful in seeing how my bit-banging was off when addressing WS2812 LED strips. The built-in protocol analyser is showing the information contained within the signal and this blew my mind at how easy it was to do.
