I ran a webcam pointed at a fermentation of Kombucha capturing frames using fswebcam running on a Raspberry Pi server. It ran for a few weeks.
You can see the Kombucha SCOBY’s forming in the video. The setup is behind the PC monitor with a desk lamp and camera pointing towards the back of the desk. This gives fairly steady ambient lighting. I grew a dozen SCOBY’s for the Summer Fermentation Class that was held on June 29th 2015.
The video should be viewable most of the time unless I am servicing the Raspberry Pi or I pulled the plug on it during a nasty storm.
