This is LED lantern modification project. I take this “kosa 6011 LED” camping lantern and made a deep modification – replaced all the internals with custom made ones – colorful piranha LEDs, PWM-controlled by STM32F103 microcontroller. Then I made a custom firmware for it with different operating modes – like flame imitation and various types of color change algorithms. See more details in the video below.

This ain’t a commercial project and I’m not going to monetize it, so I decided to share my project files, if someone will like to repeat it or use it for own education.
I’m not sure this LED lantern is available outside Russia/CIS with the same name “kosa c6011 LED”, but since it is a Chinese-made thing, I’m pretty sure it available under some different name / brand.
Check this video about the project, I made 2 versions of the video.
