Toot

A team of our students made a programmable Christmas tree that is on display at the entrance to the math building.

It's a real feat of engineering and programming, and I am very proud of our students. It has 500 color led lights that are fully programmable. The students wrote software for measuring the xyz coordinates of each light, and made a programmable interface that anyone can use at https://jelka.fmf.uni-lj.si (in Slovenian “jelka” means "fir") to make their own pattern. They wrote a Python library, a Docker interface, and even created a custom Scratch-like visual programming language for controlling the lights. And 3 simulators, as apparently one was not enough. It's all at the web site.

If you are or know a teacher who would like their students to participate, see the contact tab on the web page.

@andrejbauer

Last year, the students were inspired by the wonderful @standupmaths video from 2020; from what I understand, the project grew significantly since then :)

@andrejbauer That’s a very nice project, and seasonally appropriate.
