I built a pocketable embedded device for students with Raspberry Pi Pico: PicoCharts! Working on this project was really fun, I improved my coding and hardware skills along the way. I also get to use it every day!
I am proud of how slick the final product is. It is very easy to use and thin so it is quite practical.
The hardware was quite challenging in this project as it involved soldering very samll (30 AWG) wires and making them reasonably tidy. This was difficult as I have little soldering experience and bad tools. But I upgraded to decent solder and a Pinecil and things went a lot more smoothly!
