At the Maker Advent Opening on 29 November 2025 at the Chemnitz Stadthalle, I hosted a workshop where participants created an origami star with a small LED light inside. The theme was to combine technology and craft — bringing together the Christmas season, origami from my home country Japan, and minimal electronics. People of all ages joined and enjoyed a warm, creative time with paper folding and simple electronic assembly.

I designed this star pattern based on Prof. Jun Mitani’s pentagonal box in his book "曲線が美しい立体折り紙".The pattern I created is open source. Please feel free to use it.



I’ll upload a video tutorial on how to fold it soon.
