I smelled smoke early this morning, so I rushed into my room and found my computer mouse burning with large flames. Black smoke filled the room. I quickly extinguished the fire, but exhaled a lot of smoke in the process and my room is in a bad shape now, covered with black particles (my modular synth as well). Fortunately we avoided the worst, but the fact that this can happen is still shocking. It's an older wired, optical mouse from Gigabyte
