Here's a peek at new newest brewing contraption. This is a Temperature Controller for my fermentation chamber (FC). This will help to maintain a constant temperature for fermentation. The FC will be a deep freezer chest, stored in the garage. The Controller has high and low temperature settings and will operate the two outlets below the control screen. If the temperature rises, the cooling circuit will turn on power to the deep freezer to reduce the temperature. If the temperature drops too low, the heating circuit will power a Brewpad (waterproof heating pad) to warm up the wort. Constant temps mean happy yeast and happy yeast means yummy beer.
