We used this PCB as part of an educational workshop about electronics. The instructions and exercises for the students are in the folder edu_resources. Unfortunately they are just available in German for now. Feel free to translate them and file a pull-request.
You can find a list of the required parts in the 1-click-BOM.csv file. It lists all the respective products at part resellers. However, for some standard parts such as the 5 mm LEDs and the switches you might want to consider buying them in bulk from another supplier because it'll be much cheaper. Here are some links:
The PCB was designed using KiCAD in combination with the svg2shenzhen plugin for Inkscape. A big thank you to badgeek for developing and maintaining this awesome piece of software which got me into PCB designe in the first place
PCBs were manufactured by PCBWay (sponsored). Order process was very simple, customer service friendly and the quality of the PCBs is great! Thanks to PCBWay for sponsoring this project and thus made our christmas workshop with local students possible.
