I created this 5-key macropad, which features an ergonomic layout for fingers to reach the keys with ease. It also features a status LED, along with a capacitor.
Challenges: I had a difficult time with the proportions and getting them right because KiCAD threw me off by so much..
Total time: It took me the entire long weekend to do this..
