I’ve made it in 2016 and this is a DIY project.
Now I’m sharing this project for free. Also on YouTube made a tutorial how to make it for yourself. But now it is only in polish language. I will made english version in the future.
To make it You must use some electronics:
Battery CR 2032 or CR 1632 – also 2025, 1625 fits.
SMTS switch – small one with 5mm fi
Slowly changing colors programmed LED – 5mm
Some copper wire – I use wires from Ethernet Cable. 🙂
