For extended cooking processes that take weeks, months, or even sometimes years, there is not currently a good kitchen-top device that can maintain temperatures above and below room temperature. This is where ‘chamber’ comes in. Using a Peltier cooler (a solid state heat transfer device), ‘chamber’ can heat or cool to maintain set temperature over long periods of time.

‘chamber’ is great for sourdough bread starters, pickling, mushrooms, yogurt, and other long processes. Below are a few photos of the functioning prototype that I’m using to keep my sourdough starter at 26 deg C.
