Hacked Fridge

To control the temperature of your fermenting beer, you need a way to cool and heat it. This is usually done by hacking a fridge to install a heater inside and to give BrewPi control over the compressor.

Solid state relays (SSRs) are used to control 110V or 230V AC power to the heater and cooler with a small control signal from the BrewPi Spark.
