My current actual project is producing a couple of high speed ramps from a Raspberry Pi Pico so I can make an oscilloscope with an X-Y input into a kind of raster display (256x256 because the DACs I have are 8 bit).
In reality though, most of the day went on putting insulation into the garage. This is great too. My last Raspberry Pi project was building a temperature sensor and it's really made me aware of how cold it is in the garage (despite a heater trying to keep things above 0C).
