Hello reader (yes, you, at the back) – apologies for no recent updates,but I’m back with the third in the series of adventures in getting some brewday control developed using the Raspberry Pi platform. Interestingly, this comes only days after the 2 millionth Raspberry Pi was shipped! In the last article I described the simple circuits we’re going to use to control the relays and also to connect the temperature sensors to the Pi. The code remains to be detailed (as does building the permanent circuits). The code to read the temperature is easy and essentially just pulls the data from

So, continuing on from my previous post on starting to use the Raspberry Pi for brewery control, this is a post about the interface aspects of HLT control. There’s a bit of circuitry here to interface the GPIO ports of the Pi to a mains powered element – the Pi shouldn’t be switching mains voltages and currents without some isolation – there’s far too much risk involved, both for the Pi and for the brewer… Usual, obvious disclaimer – folow these instructions at your own risk – you are responsible for your own actions; if you’re unsure, get someone to check

First up, this is not a post about framboise, lambic fruit or any other style beer with fruit – though I have some good ideas to work on homebrew-wise, including a gooseberry witbier and a sloe porter. More of that later. This is instead about first steps towards some brewery automation, and I’m looking to use the opportunity to start to use and learn about the Raspberry Pi. I have some control already later in the brewing process with using an ATC to control the fermenting fridge, but this is about introducing some control earlier  in the brewing process. My first
